Geography case studies on Sri LankaHi, my name is Phil Brighty. The title for the blog Geosrilanka comes from the fact that I lived and worked in Colombo  for nearly 7 years, and came to really love the country and its people. You will find case studies focussed on geographical  issues in a developing country: Sri Lanka. Up until recently South Asia has been a neglected are for study; however, it is a rich area for study geographically and,  just as importantly, offers new material for students. As a teacher I was always on the lookout  to get away from the same old examples everyone uses…which is why I set up this blog. I hope you find the case studies useful.Apart from Geosrilanka I write mainly for for GeoFactsheets.. However, I have also published in The Geographical Review, and Geofile Online.Before that I was Head of Geography at The Sixth Form College Colchester and then was based at Colombo International School as HOD and Head of Secondary School. In the past I have been an A level examiner for OCR, AQA and also an examiner for IB diploma geography.Sri Lanka is a great place to undertake fieldwork for A level geography..most places are accessible and value for money; plus for students it can be the trip of a lifetime because with careful planning they get to experience what regular tourists never can:If you are interested click on the live link above to find out more..What would be interesting to know is how people are using the case studies..are students being referred to the site? are teachers using them in class or as research and prep for lessons?The blogs are very much summaries of often large numbers of links, websites etc. If anyone wants to know more, wants help with resources, especially with Sri Lanka in mind, then I would be happy to respond.There is an opportunity to comment so do send comments in and I will put them up.Making sense of the Sri Lankan monsoonDengue Update; dengue cases could top 150,000 this year!Colombo Garbage Dump CollapseThe Indian Ocean Monsoon part 1: is the monsoon becoming less predictable?Dengue UpdateChallenges ahead for the Sri Lankan Garment IndustryNext Up:  The Monsoon, Drought and Global Warming in Sri Lanka; prospects and problems Sri Lanka has just experienced its worst drought for more than forty years. Reservoir levels fell to around 33% of capacity and many tanks dried up or are at low levels. Agriculture, particularly rice padi production has been decimated. One estimate suggested that by November 2016 only 35% of the  nation’s rice padi had been cultivated and that over 1.2 million people have been directly affected by food shortages and loss of income. H.E.P. production was also affected and led to power cuts being imposed during the latter part of the year.This was the picture for southern India and Sri lanka as of May this year:source: IWMIYou can find this map for yourself on the IWMI site (they are based in Colombo) and also on the Relief Web site; When it is amplified you will see that a large area of Sri lanka and Tamil Nadu are speckled brown (severe or extreme drought). This was a situation that had been developing for some time but it has come to a head in 2017.Droughts can be categorised in a number of ways;So what we now understand is that rainfall levels fell way short of normal; i.e. there was a rainfall deficit which affected pretty much everywhere apart from the south west of the island, as this map re-printed from Global Risk Insights shows: With the exception of the North West around Puttalam it is the DRY zone which has been affected most. This is the zone which tends to rely on the North-East monsoon for its rainfall. So that means November / December. For the rest of the year high temperatures prevail. High temperatures lead to high evapo-transpiration rates (water loss from the soil and plants) and the soil dries out, storage tanks and reservoirs shrink.source roar media networkSo long as the monsoon rains return in November then all is well and the cycle continues supporting padi production, animal grazing and so on. However, what if the rains are much less than usual? Then soil moisture isn’t replenished and farmers run out of water. That is drought on 3 levels!So what happened to the monsoon in 2015/6/7 especially the North-East Monsoon? Without rainfall data for 2016/7, we can only speculate but anecdotally at least all the evidence points to a failure in the 2016 North East monsoon especially in the Dry Zone. This is borne out by the pattern of rainfall deficit shown on the  rainfall data map where there is a high rainfall deficit pretty much everywhere, South-West excluded.Possibly this is part of a long term trend. Looking at rainfall data  for the period 2000- 2015 there is a suggestion that in the dry zone rainfall may be declining:(Even then the paradox is that whilst rainfall levels may have not dropped that much in some areas the view of senior meteorologists is that  the rains are coming in more intense bursts, that is shorter periods of more intense rain with longer hotter periods between them (attributed to a general rise in temperatures across the South Asia region giving rise to  enhanced convective activity or storm clouds) So the significance of this is that the more intense the rainfall the more of it will run away(surface run-off) rather than soaking into the ground and recharging water tables.)The other information we have to factor in is that 2015/6 were both strong El Nino years. El Nino is associated with suppressed convective uplift (the sort that stops rain clouds forming)  2016 also saw the Indian Ocean Dipole in negative phase so the Eastern Indian Ocean was warmer than normal which brought heavy rains to Western Australia but suppressed rainfall over southern India and Sri Lanka.So the dark brown areas are areas of negative rainfall anomaly; i.e. much less raeinfall that normal. You may just be able to make out a big smear of brown across southern India and Sri Lanka. It means that rainfall was well down on the average for June and August.The El Nino has weakened and is now in neutral as is the IOD but clearly the climate system has taken time to revert. What we won’yt know for a few months yet it how the October/November inter-monsoon period is going to react or what will happen to the North east Monsoon.a.  As of 20 August, more than 1.2 million people across 19 out of 25 districts remained affected by drought. Northern, North-Central and Eastern Provinces were reporting low levels of water for agricultural, drinking and household use. The failure of two harvests in 2017 has raised concerns for the food security and livelihoods of affected communities. (relief web).b.  Reservoirs  fell to dangerously low levels, many at only 30% of normal levelsc.  Plus increasing numbers of people are not getting either enough food or the income to buy food. The country’s rice harvest is likely to be down about 17 percent from the 4 million tons recorded in 2013, which would make it the lowest in six years. (IRIN). This has led to Sri Lanka having to import riced. There is a definite geographical pattern to the impact of this drought. It is the (mainly) poorer and more vulnerable communities of the North and East, still weakened by the effects of the Civil War,  who are suffering most as this graphic taken from a local newspaper indicates;What this drought has shown above all is that water insecurity has become a major issue for Sri Lanka.Plus there is not enough water transfer capacity to mover water from the wetter mountain zones into the dry zone to irrigate crops and support the population.All of which makes Sri Lanka vulnerable to climate shocks such as the current drought.2.  Hydro Electric Power generationDuring normal years when reservoirs are at capacity Sri Lanka can generate around 50% of its needs from HEP. Currently the country is supplying just 34% of its power supply from HEP meaning an increasing reliance on imported fossil fuels which pollute the environments and impact on an already delicate balance of payments situation for the country.Plus there are other factors which impact on water demand to take into account:All the indications are that climatic hazard events will become more, not less frequent in the coming decades. So, what to do?2. Conserve waterSo here you can see untreated effluent running into the Kelani River from a local cand here is a fairly typical scene in a watercourse by a low income settlementIn rural areas with agricultural runoff pollutes rivers and streams. In urban over-crowded cities, there is biological contamination of ground water.  Except for pipe-borne water supply, irrigation and hydro-power schemes, in general water resources in Sri Lanka are managed very poorly. Regulations are available to control most water related problems but enforcement of these regulations is lacking. … and this is the point. Water is becoming an increasingly scarce resource. There is a real need to conserve existing supplies and re-cycle water effectively.3.  Develop exiting inter – basin water transfer schemes. In other words mover water by pipeline and channel transfers from the wetter areas to the dry zone. The Mahaweli River basin project initiated in the 1970’s  was intended to take water from the mountains to the dry zone; and it does. But is that enough? Question rather than answer and obviously any addition to existing arrangements would be expensive. The question is; does the government even consider whether adding to existing water transfer schemes is worth investigating?4. Innovative methods; harvesting rain water. I found this extract printed in the Daily Mirror 2016;Water that falls on a roof of 1,000 sq m in Colombo (average rainfall is 2,000 mm) during a period of one year would be around 2,000 cubic meters (i.e 2 million litres or app. 400,000 gallons). The actual cost of this amount of water would be around Rs. 90,000. The rainwater that falls on the roofs of extensive buildings such as hospitals, schools, housing complexes etc. could be collected in tanks in the premises itself. Water thus collected could be used for numerous domestic purposes. Currently we use chlorinated water suitable for drinking to wash cars, water plants, clean toilets etc. Using rainwater for these activities would reduce water bills, save purified water, which could be used for drinking purposes. Once the collection system is installed there is no additional cost involved except on pumping of collected water to the main water supply system. (Dr CS Weerearatna Daily Mirror October 2016)source pinterestThis is one simple idea which involves collecting rainfall from roofs and storing it in large tanks either fully or partially underground. The only costs involved are the installation costs plus the cost of pumping the water from the tank. Is this being promoted by the government? It doesn’t seem to be. But these are simple low-tech solutions, so it is surprising that so little is being done.This article began by charting the development of the latest drought to hit Sri Lanka. Monsoons will fail from time to time, that is a given. Although we understand more now about why droughts  occur  we are powerless to stop them happening. All of which means that when they do occur it is important to have strategies in place to help people cope; to reduce their vulnerability to drought. Sri Lanka is not alone , in facing the dilemma of what to do and how to do it. Water security is an issue throughout South Asia. What this drought has done is bring into sharp focus the need to be planning now for the next drought or Sri Lanka will simply have to go through this crisis all over again.Rainfall in Sri Lanka is not predictable and monthly averages mean very little. Although the 3 main rainy seasons start pretty much on time (give or take a fortnight) the amount of rain that falls during those seasons is variable from year to year,and in the North and East the dry season may be getting drier. So why is the monsoon so variable both from one year to the next and over longer periods?First a little bit of simplified theory.Surface temperature, air pressure and surface windsthings you need to know if you don’t already:a.  heating from below – convectionb.  warm ( less dense ) air rising over cooler (more dense air ) – frontal rainfallc.  where two air masses meet or converge – convergence.Rising air is associated with cloud formation and rainfall. (air cools, condenses – cloud and rain)a.  cooling from below which causes air to become heavier at the base and sink towards the surface.. orb.  upper atmosphere convergence below the tropopause which forces the air downwardsDescending air is associated with dry conditions ( descending air heats up)The diagram below gives a general idea of how that works. Air in a low pressure cell rises into the upper atmosphere until it reaches the boundary with the troposphere ( the tropopause) where it is prevented from rising and moves sideways. Being much colder and/ or where there is upper atmosphere convergence, the air sinks back to the surface creating a circuit if you like. Fig 13.  Surface winds move from high pressure to low pressure There are three processes at work and because they operate semi-independently of one another it makes the understanding of how the monsoon operates tricky. The Inter – Tropical Convergence Zone ( ITCZ )The ITCZ is a zone of rising air (Low Pressure) located around the equator where the water (SST’s) is warmest. This is convective uplift. Rising air is associated with cloud formation and rain. At around 30 degrees of latitude either side of the ITCZ are regions of descending air. The sub-tropical high pressure belts. Surface winds blow from the high pressure belts inwards towards the ITCZ.Fig 2. Global Circulation PatternsNotice the don’t flow at right angles to the equator. The actually move as curved lines; north -east to south – west in the northern hemisphere, ( The North East Trade winds) and south – east to north west in the southern hemisphere (the South East Trade winds). This is due to the coriolis force; check it out here.So why do winds migrate?Fig 3 The migration of the ITCZFig. 4and what this shows is that:Figure 5 is a more detailed version of the process.Fig 5Notice the region of high pressure in the southern Indian Ocean. This is called the Mascarene High; for more try out this link. I will get back to this later in the blog.So the migration of the ITCZ explains the seasonal reversal of wind patterns and broadly when that happens. However, it doesn’t explain why both the North East and the South West monsoons are so variable in terms of how much rain falls. That is because there are other forces at play which have a direct impact on the pattern of SST’s which in turn control surface air pressure and winds.They areEl Nino is a Pacific Ocean event, right? Well yes it is, but what happens in the Pacific Ocean has a knock on effect on the circulation patterns in the Indian Ocean; and it is complicated.A.  More backgound: The Walker Circulation PatternThe Walker circulation is an ocean-based system of air circulation that influences weather and is the result of the difference in surface pressure and temperature over the western and eastern tropical Pacific Ocean. Normally, the air over the tropical western Pacific is warm and wet with a low pressure system, (rising air) and the cool and dry eastern Pacific lie under a high pressure system (descending air).This creates a pressure gradient and causes surface air to move east to west, from high pressure in the eastern Pacific to low pressure in the western Pacific. Higher up in the atmosphere,west-east winds move in the reverse direction to complete the circulation.Fig 6 ENSO neutralWhat you need to notice is that there is a major zone of uplift over south east Asia. Also note the area of descending air over the Middle East and the weaker uplift zone over East Africa. That helps to maintain a predominant west to east surface air flow over the Indian Ocean Basin which reinforces the monsoon.So if you are ok with that then let’s look at how the El Nino upsets everything;B.  ENSO events; El Nino and La NinaEl Nino is an ocean sea surface temperature event that is now pretty well understood. During El Nino events the normal Walker circulation pattern weakens, allowing warmer water to migrate eastwards towards the coast of South America. At the same time the main zone of uplift (low pressure) moves towards the central Pacific and in the western Pacific the surface airflow reverses to become west to east.Notice now that there is descending air (high pressure) over South East Asia, and a strengthened zone of upfift over East Africa. The net effect is to establish an easterly airflow over the Indian Ocean, working against the South West Monsoon in particular.Fig 7So what you might expect is that in El Nino years the South West Monsoon is weaker over South Asia. This in turn can lead to reduced rainfall, and possibly, drought conditions.La Nina is the reverse of El Nino so far as the Pacific Ocean circulation is concerned. Here the warmer water moves into the western pacific intensifying the zone of uplift over South East Asia ; the cell moves westwards effectively. Notice the zone of uplift over East Africa has gone.. bad news for those areas.. but the west to east airflow over the Indian Ocean pattern strengthens intensifying the South West Monsoon.Fig 8So to summarise so far: the two influences on rainfall we have looked at areIt is worth noting that these events act independently of one another..But now we have to add the third element; The Indian Ocean DipoleC.  The Indian Ocean Dipole First identified in 1999, the Indian Ocean Dipole refers to spatial differences in sea surface temperature over the tropical Indian Ocean. There are three phases:Fig 9Increased convection over the western Indian Ocean (warmer air rise = low pressure = rain) has a knock on effect for the monsoon; why?ok so remember that the SW Monsoon rules in May – August; the ITCZ migrates northward and the winds blowing from the SE become south westerlies when they are dragged across the equator into the northern hemisphere. ( check out figs 3&4 ) Plus being warmer the relative humidity of the air is increased. This should mean the monsoon intensifiesFig 10Here the pattern reverses. To the west of India there is a zone of descending air which surpresses the moisture content of the surface winds and leads to lower rainfall. D. Putting it all togetherThese three influences don’t necessarily synchronise with one another and are pretty much independent of one another as well.Generally ENSO impacts the Indian Ocean by re-organising the atmospheric circulation but so does the Indian Ocean Dipole.SoBut as I wrote earlier.. it now gets tricky.2.  Not only that but the ENSO and Dipole events vary independantly, in intensity and impact.Last point; various phases of both ENSO and the IOD can occur concurrently but at different relative strengths. Confused yet?One example; a moderate El Nino such as occurred in 1997 should have lead to a poor monsoon over India but it didnt. this was because it was outweighed in influence by a stronger positive IOD event and in 1997/8 India received above average rainfall. This puzzled many meteorologists and led to the discovery of the IOD in 1999.So what doe the evidence show? The following table illustrates how the different events have come together to affect the monsoon in recent years.An IOD event can offset the impact of El Nino or La Nina although in 2004 it was El Nino that “won”.  So that’s what it comes down to.. a dynamic system driven by variations in sea surface temperature which drive atmospheric circulation patterns.The complicating factors are that:Looking then at all of this: It does shed some light, however, on why monsoon rainfall is highly variable and, therefore, so difficult to forecast. It also may help us to understand why South Asia is prone to periodic drought; the subject of the next article.Footnote: Don’t forget Global Warming!!According to Dr. Evan Weller abased at Monsah University in Australia global warming is set to complicate matters even more.As climate changes, so sea surface temperatures will rise, but the increase won’t be even. Some regions will warm more than other regions. Over the eastern Indian Ocean, the waters to the north are predicted to warm faster than those in the south. This will have the effect of  pushing the ITCZ further north over the eastern Indian Ocean. It will also affect the SST  gradient north to south and that impacts on pressure differences and ultimately circulation patterns. The question is how will this interact with ENSO and IOD events and what effect will that have on the climate of South Asia. It may well serve to intensify the south west monsoon but there is no agreement on that at the moment. It is also possible that the location of the warmer water pool in the Indian Ocean (both positive and negative phases) may shift in location and this could also affect the local surface wind patterns. There is still much that is not understood!What is happening to the Indian Ocean monsoon? Has it become less predictable? Is it becoming affected by global warming? and finally, are droughts in Sri Lanka getting worse as a result?The monsoon rains are important not only for agriculture in the region but also power generation.  Sri Lanka generates around 40% of its electricity from H.E.P. for example. So getting an understanding of how the monsoon seasons work is really quite important for a whole range of reasons. a.  In the first of three linked articles I am going to be ysing rainfall and drought data to find out what is actually going on.b.  The second article will look at what drives the monsoon, in particular the interplay of 3 factors and how they lead to changing patterns of sea surface temperature ( SST ), pressure and wind patterns, and how this affects rainfall. The three phenomena are:c.  The third article will focus on patterns of drought in Sri Lanka.For this article I am using rainfall data for 4 stations; Batticaloa, Jaffna, Colombo and Galle. I had data for the period 2000 – 2015 and added to that data for the same locations for the period 1985-90. (I would have liked more ie; 1980 – 2000 but I couldn’t access the data).So my sample size is  small and skewed towards the later period but it does give some indication of trends.I chose some simple statistical methods to yse the data;  I looked at each month in turn  over the 15 year period and calculated for each month and for each station:The coefficient of variation  ( Cv )is a measure of the spread of data that describes the amount of variability relative to the mean. It is calculated by dividing the standard deviation by the mean.values close to zero indicate that the the data set shows a lower degree of variability and vice versa; In the results section  I will give just the Cv (not the mean or SD ) So if the data shows a Cv of say 0.50 what that suggests is that for any one year  the actual rainfall received will be in a wide range: 50% above and below the mean. Let’s say average rainfall is 500mm for a month then with a Cv of 0.5  the actual rainfall could be expected to fall within a wide band 250 mm to 750 mm.Not very predictable.I carried out the same calculation for the 1985-90 periods so that I could compare the two. I also looked at the pattern of rainfall through the year to see if it changes at all. I wanted to know the following: The location of the 4 weather stations The monsoon seasons in Sri Lanka;There are four monsoon seasons in Sri Lanka:That has an impact on the rainfall distribution for different parts of the country;                                                                                                           SWM                                            SIMnote: what becomes apparent is that where the monsoon seasons are concerned you cannot generalise; Sri Lanka is different from the sub continent of India. Even within India there are significant departures from the generalised “norm”; so the lesson is not to accept broad generalisations from text books where climate is concerned.                                                                                                                                                                        NEMnote the vertical scales on the two graphs are not the same; the graphs are there for illustrative purposes onlyOf the two, Batticaloa looks like it is the most vulnerable to drought for two reasons; when the rains failLooking at the data there are a couple of general points to begin with: Which bring me on to the last point in part one; why is the rainfall so unpredictable? The reason is that there are several factors at play.all of which affect sea surface temperatures, and therefore pressure and wind systems.Simple it isn’t?As a taster then here is something to be thinking about.ENSO events:weak            2004/5, 2006/7moderate      2002/3, 2009/10very strong    2015/6IOD dipole:positive:         2006, 2012negative:        2010You could have a look at the summary of rainfall data above and see where there may be potential match – ups.Part 2 looks at how it all works( for those who are interested in the detail; I have the raw data available on request )The average Cv for 1985-90 is 0.67; the average Cv for 2000-2015 is 1.01However the Cv for the NEM is marginally lower for the period 2000-15Concentrating on the period 2000-2015:The average Cv for 1985-90 is high; 0.86 and is even higher in 00-15; 0.97Looking at the period 2000-15A possible question to investigate is the degree to which Jaffna may be affected by the SIM given its location.Common to bothat around 0.06 the Cv for both periods (85-90 and 00-15) is highLooking at the period 2000-15In comparison with Colombo the Cv’s are slightly lower than for Colombo but still >0.5 for both periods but there is no significant difference between the Cv values for the two time periods.Looking at the period 2000-15Common to Colombo and Galle     Colombo generates well over 1000 tons of garbage every day most of which ends up at the Meethotumulla rubbish dump on the outskirts of the city., because until now there has been no alternative site for waste disposal in the city (if you discount the cs that is; which many residents seem to see as an alternative waste dump)On April 14th a large section of the dump collapsed onto the surrounding settlement resulting in an estimated 28 deaths, ( although this figure may well rise) displacing a further 625 people and extensively damaging 145 houses.The sheer scale of the dump, which dominates the skyline around should have been enough to warn authorities of the need to take action. source: Hiru News The dump contains an estimated 24 million tons of garbage (made up of all types of waste) rising to upwards 90 metres and covers around 7 hectares. It dominates the entire area.In May 2016 the dump had to be closed for 10 days due to extensive flooding and the Colombo Municipal Council was forced to obtain a court order to remove 3000 tons of accumulated waste to the Piliyandala site to the south of the city.Questions:On 15th April, The Daily Mirror (Sri Lanka) published a scathing attack on the authorities, by the pressure group; Decent Lanka 2015,  in the wake of this latest disaster the headline of which reads: “Dump, dumber, dumbest” The article lays the blame squarely at the feet of local and national politicians: please click on this link and read the article:Key quotes (source Daily Mirror. lk)The relevance of water in this context, is that percolating water destabilises loosely compacted mounds of garbage and slope failure is always going to be the most likely outcome. The surprise is that this disaster has taken the authorities by surprise. It was a disaster waiting to happen.The garbage dump would have become saturated by water percolating down through the unconsolidated waste.Therefore, the garbage and the mound would have become “top heavy”. Water seeping out at the base of the tip would have further de-stabilised the base of the mound, and the slope failed.To quote American Geophysical Union (AGU): blog Dave Petley“It is undeniable that this site was unsafe.  The garbage mound is clearly too high and too steep, inviting a rotational failure.  With houses so close to the toe of the slope the hazards were severe.. This is another case in which we know and understand the hazards, but fail to manage them.  The results are once again tragic.”This photo taken by the Sri Lankan Airforce shows clearly what happened. The base of the slop failed and half of the mound fell away onto the houses below.The question is not how this disaster could have been prevented BUT:I found this extract in Ceylon Today:The Ministry of Megapolis and the Western Province Chief Minister are at loggerheads over the Meethotamulla Garbage Dump, says Provincial Council Member from Kolonnawa Saliya Wickremesinghe. He noted that last May Western Province Chief Minister Isura Devapriya had promised a solution, which involved negotiations with a British company that provided waste management solutions. Speaking to Ceylon Today, Wickremesinghe added that Devapriya then promised to commence work at the site within six months from last May. So far, the people of Meethotamulla had not witnessed any progress.A case of “fiddling while Rome burns” to borrow a metaphor.It would be unfair though,  to blame the lack of a solution on the current government alone. This dump dates back to days of the previous regime. So both should shoulder the responsibility along with Colombo Municipal Council who administer the site. The fact is that nothing has been done to make this dump safe, and so the worst fears of the local residents have been realised.What this latest episode does do, however, is to bring into sharp focus the absence of any coherent solution to Colombo’s garbage crisis. In another blog I examined one possible solution; the Aruwakkala project. However, even this proposed solution is not straightforward and raises significant environmental concerns over its viability; click on this link to articlethe proposed site for the garbage dump close to PuttalamCurrently there are no secure and safe Sanitary Landfill sites in Sri Lanka and incineration is not considered to be viable due to the high moisture content of much of the waste.So to quote a phrase: “what to do?”It is an inconvenient truth that sanitary landfill sites will need to be found for the growing volume of urban waste. If the government’s plans for Megapolis in Western province materialise then even more waste is likely to be generated in future. Planning needs to begin now!Perhaps the authorities could look again at incineration plants but they come with their own “health warnings” in terms of pollutant gases escaping into the atmosphereOtherwise the accent has to be on generating less waste and recycling more of the waste that is produced. Some community recycling schemes have been implemented amongst middle and lower income communities, for example: Community Based Solid Waste Management Project in Matale and Ratnapura Cities undertaken by the Colombo based NGO Sevanatha (www.sevanatha.org.lk). The fact is that:However, it doesn’t get done, partly because communities don’t buy in to these projects unless they can see the potential for some financial gain. Partly because the political will is not there.And there are other constraints:It is unlikely that one solution alone will be enough to deal with what is fast becoming a crisis. Responsible land fill, incineration and recycling are all aspects of the solution. What it does need is for politicians to focus on finding a solutions rather than dispute with one another. It is all very well to develop ambitious plans for a brighter tomorrow for Sri Lanka; viz the Megapolis project (see elsewhere in this blog); however, they need to get the simple basics of good environmental management right first.Some useful referencesClimbing out of the garbage dump : Envirtonmental FoundationSevanatha: http://www.sevanatha.org.lkThe headline photo: source Sri Lankan Air ForceEvery year on average over 200 elephants are killed and 60 to 80 people lose their lives as aresult of elephant attacks. With maybe no more than 5000 to 6000 elephants left in the wild in Sri Lanka time seems to be running out for the Sri Lankan wild elephant.At one time wild elephants could be found in most parts of the island. Now they are confined mostly to the north-central region of the island. They were driven out by hunting; for example on the Horton Plains where elephants once used to be plentiful, as well as the land clearances which created the vast tea and rubber estates.Elephants and People; the old daysThe traditional agriculture of the intermediate and dry zones is called Chena. It is a version of slash and burn. Chena cultivation is dependent on the rainfall, so at the onset of the monsoon, a patch of forest was cleared and cultivated for about 4 to 5 months and then abandoned. This then created low scrub/ woodland ( secondary regeneration) which is the habitat the elephants preferSo, traditional Chena cultivation was compatible with maintaining the elephant population and, in fact, meant that people and elephants didn’t come into contact as often as they do now. The elephants simply moved on to abandoned and regenerating forest when the farmers moved on to open up another patch of forest.What has changed?The extension of sedentary agriculture in the centre and east of the country which began in earnest in the 1970’s was the single change that brought elephants and people into close contact and which has put the elephants at  risk of extinction.The main causal factor is the  Mahaweli River Development Scheme (an irrigation scheme) Aimed at agricultural development it was begun in the 1960’s but accelerated after 1977.The Mahaweli schemeThe project had a number of inter-related aims:Settlers were encouraged onto the newly irrigated lands with the promise of land, a house and irrigation water. Apart from rice, the staple of Sri Lanka, farmers were encouraged to diversify into sugar cane, soya, corn, vegetables, fruit and cash crops.The area under rice cultivation almost doubled to 87,000 hectares whilst rice production rose from 164 million tonnes p.a. to 471m tonnes p.a.Land under other crops also doubled in area as a result of the  programme. However large areas of secondary forest were lost and the traditional chena system was largely  abandoned because it was not profitable.and you have to question why large areas around Udawalawe in the South have been turned over to sugar cane production and at what cost? Surely a crop that Sri Lanka doesn’t really need; ask the 20% or so who are type 2 diabetics for example…And the result:The Farmer’s story Kalawagala is a small agricultural village with approximately 200 + families and a population of around 1200. The farm economy is centered on padi (or rice) cultivation, vegetables and fruit.Hinnimama is typical; along with his family he farms around 3 acres and grows padi rice plus melon, pumpkin, okra, sweet corn, green grains long beans sesame and brinjal. Some farmers may also keep a few buffalo from which they sell curd. Apart from rice which is irrigated all the rest rely on the seasonal monsoon.He would expect to grow crops in three cycles through the year (which he calls Chena) ; the more water demanding crops first and so on, and make around 100,000 rupees plus sales of rice surplus; each cycle yields around 30000 rupees dependent on amount of rain.For Hinnimama there are 2 problems:He told me that:There are electric fences surrounding the village, which are supposed to keep out the elephants, BUT the elephants kick them over causing the electric current to fail and they walk through the gaps. (one ranger told me he had even seen an elephant jump a fence). The fact that the fences are poorly maintained doesn’t help Hinnimama to have much confidence that the Department of Wildlife Conservation (who are responsible for managing the situation) can do much to help him.As a result, Hinnimama sleeps out in temporary shelters on his fields most nights. He has little choice and he feels he has no alternative but to drive away the elephants with whatever means he can employ. These methods can include shouting, using firecrackers or home made explosives, raising the voltage on the electric fences, poisoning, digging pits and possibly (although he wouldn’t say so) shooting the elephants.The elephants storyRecent research has uncovered a lot more information about the Sri Lankan elephant:from the Sunday TimesTo accommodate there elephants the number and size e of protected areas needs to be much biggerelephant countryElephants were well established before commercial farming pushed into the interior. In simple terms they were there first. However, they have been squeezed out of their traditional “range” lands. Their alternatives have been shrinking every year.The net result has been that elephants and villagers are increasingly competing for the same space with disastrous results all round.Managing the Human – Elephant conflictSo far the main response has been to try to keep elephants and farmers apart. This has been attempted in the following ways:Problems a fence pushed over by an elephantThe Main Point:Translocation of elephants into protected areas keeping them there and finding enough food for them is just not sustainable; a new approach is needed.New Management for OldOne such approach is suggested by The Centre for Conservation and Research in Sri Lanka:They argue that Management of outside areas can be achieved by regulating Chena cultivation, so that:This means going back to a form of slash and burn; Chena. But Chena farmers would need to be financially supported and that does not appear to be a likely outcome. In any case would the government be able to persuade the second/third generation farmer/ settlers to accept this? It seems unlikely.The Sri Lanka Wildlife Conservation Society (SLWCS) takes a more practical view.The idea is to engage with people at the grassroots level:Mission: “to build capacity, foster leadership and empower citizens to support sustainable, long term conservation success.”They adopt a range of innovative approaches which are all aimed at helping the local people live in harmony, not in conflict with elephants, and which are sustainable.Here is a summary of some of their projects:In one of the newer projects they are experimenting with beehive fences, where beehives are strung out along fence boundaries. Elephants stay away from bees and so the hope is that a network of such fences will deter elephants form invading farmers landsee: http://elephantsandbees.com/sri-lanka-beehive-fence-progress/SummaryThe future for elephants in Sri Lanka is far from secure. There are signs in the media and in various pronouncements from the authorities that the threat to the Sri Lankan elephant is now being taken increasingly seriously.Tourism can  play a part. Around 20% of tourists visit Sri Lanka hoping to see elephants in the wild. What would the loss of the wild elephant do to the tourist trade? What does the decimation of the elephant population do for the image of Sri Lanka?The key to protecting the elephant is a multi layered strategy;If villagers can be helped to see the economic sense of maintaining the elephant population (I think arguments about biodiversity don’t cut much ice), then this may be the way forward in terms of putting a stop to the pointless and very sad loss of life we are seeing today.Stop PressReport from the Sri Lanka Wildlife Conservation Society is worth a real close look; check it out now In 2014 an estimated 300,000 men and women left Sri Lanka to work primarily in the Gulf States. The majority of men went into the construction industry whilst the women accepted jobs as housemaids. They went because they wanted to provide for a better life for their families, and the government was happy for them to go; not least because the money they send back (remittances ) amounts to $7billion; or 9% of GDP.What the migrants didn’t know or expect was that the contracts they were promised would never materialise and many of them would end up working in conditions which amount to modern slavery.This recent report in the Sri Lankan Daily Mirror is a good place to start: www.dailymirror.lk/article/Fotune-favoured-Rani-from-the-jaws-of-death11936Sri Lanka does not rank highly on the Global Slavery Index, yet pollsters estimate there are approximately 26,000 Sri Lankans trapped in a form of modern slavery in 2016;My guess is that you might find this hard to believe, but that is because:You can think of three groups of factors; geographers will already be familiar with them:The top destinations are Saudi Arabia, Qatar, The Emirates and Kuwait with smaller numbers heading to Oman and Jordan. Whilst Western province is the biggest exporter in terms of numbers; in terms of the % of the population it is, in fact Ampara Trincomalee and Puttalam who export the biggest % of their population; (around 3%) annuallyThe migrants are often recruited by unscrupulous and unregulated agents on the promise of high incomes. The agents or employers not only pay their fares, but also arrange for passports and visas, sometimes illegally.Migrant labourers often receive a monetary advance as an incentive to work overseas. What they are not told, or don’t realise is that these incentives will bind them into debt upon arrival in their host country. Worse is to follow: recruitment agencies in the host country regularly commit fraud by changing the agreed upon job, employer, conditions, or remuneration after the worker’s arrival.A recent report alleged that the police and other officials in Sri Lanka accept bribes, and some sub-agents reportedly work with officials to procure forged or modified documents, or genuine documents with falsified data, to facilitate travel abroad for those desperate for a better life. The problem is that these documents are not legal. The migrant enters a country with these documents and is immediately at the mercy of their employers who could report them at any moment.The report also observed that the Sri Lankan government does not have the ability to regulate sub-agents under the SLBFE, which officials recognized as a problem contributing to trafficking.The situation is made worse because the migrants have little knowledge of the situations they are going to end up in. For domestic workers in particular, this involves the Kefala system, which ties the domestic worker to one employer, effectively giving that employer full control over the migrant worker. (click on the link to check this out)The reality is that the migrants end up in slavery. Their passports are often taken from them. Employers routinely pay well below what the workers were promised, and sometimes refuse to pay their workers at all. Housemaids in particular live under conditions similar to house arrest: subject to mistreatment, abuse and both physical and sometimes sexual violence.The situation for the women who end up in domestic work can be grim and there are plenty of examples you can find for yourself by going online: For example have a look at:see link; serious violence in the Gulf Statesthis an extract from another victim’s story“Even if I went to bed at 3:30 a.m., I had to get up by 5:30 a.m I had continuous work until 1:00 a.m., sometimes 3:00 a.m…. Once I told the employer, “I am a human like you and I need an hour to rest.” She told me, “You have come to work; you are like my shoes, and you have to work tirelessly.”The conditions were getting worse. I told the employer that I wanted to leave but she would not take me to the agency. [Her husband] would say, “You want to go, you want to go?” and he would pull my hair and beat me with his hands. He went to the kitchen and took a knife and told me he would kill me, cut me up into little pieces, and put the little pieces of me in the cupboard By this time they owed me four months’ salary.There are more and more innocent women going abroad, and planning to go. It is up to the women to care of themselves. The [Sri Lankan] government gets a good profit from us; they must take care of us. They must do more to protect us.”Kumari Indunil, age 23, a former domestic worker in KuwaitThis You Tube clip speaks for itself and needs nothing extra from meSimple answer? Nobody cares!To begin with  there is a need to collect data to improve understanding of:Mapping the results allows NGOs and government organisations to focus initially on areas which are hotspots of out-migration to the Gulf and then to develop a better understanding of the migration process.After that there are two approaches that could be considered.2.  Help local people to develop small scale businesses using cheap forms of credit and support from local NGO’s like Sevanatha and The Institute of Women in Management  and the women’s co-operative bankcheck out the links and you will see that what they do is:What the above can do is help to create cohesive communities and develop viable economic alternatives to migration for local people.3.  Educate people to the stark realities of life on a construction site in Qatar or imprisoned in a home in Saudi Arabia : a negative reason not to go.AT the same time pressure must come from politicians, NGO’s the media and local people to force the authorities to ensure all agents are properly registered and licensed via the SLBFE for example. The issue of licences must be on the basis of conditions, which are stringent, open, and subject to scrutiny and enshrined in law. All agents should be required to lodge a bond with the authorities to be used to meet the costs of repatriation, and loss of earnings where migrants fall foul of local practices in the Gulf and need to return home.Unlicensed agents must be prosecuted, along with corrupt government officials and police, as must those who knowingly mislead clients and do not exercise a duty of care. At present very few licensed agents are audited and few are ever prosecuted.b.  Addressing the situation in the Gulf States The surest way to force a change in attitudes amongst employers in the Gulf is to dramatically cut down the flow of migrant labour. In that respect the SLBFE should be taking pro-active steps to warn migrants of the potential situations they could find themselves in.In the meantime: there are issues to overcome:Steps that should be taken:Within the Gulf States the embassies of the “exporting” countries should at least have staff fully trained to support abused victims. There should be a list of all addresses where migrants are living; regular checks made on them visits to ensure health and well being, wages are being paid, and they are not subject to mistreatment or abuse.Key legal reforms are needed to ensure the most vulnerable workers, particularly domestic workers, who must be covered by basic labour law protection.Steps must be taken to make certain victims are not further traumatized by arrest and detention if they run away to escape violence or exploitation.Despite their contributions to their host countries, women migrants are not generally assured of basic protection. A simple 40-day mandatory training programme by the SLBFE does not simply address the concerns of those who seek foreign employment. Employers and recruiters alike must be held responsible for their role in exploiting the helpless workers.What this needs, however, is co-operation between the sending countries and the host countries. However, if the host governments are unwilling to comply then governments like that of Sri Lanka should take steps to stop the flow of migrants to those countries, which they can do at the exit airports. Although painful in the short run tapping the economic potential of the poor at home, turning them into productive individuals through community and self help schemes could be a way forward and would spare many the fate that awaits them at the hands of  employers in the Middle East. https://www.youtube.com/watch?v=Z7pkhFnwXkImeasures should be taken to challenge perceptions about migrant workers, in order to recognize their values and contribution to the development of the country.See more at: http://www.dailymirror.lk/115002/Vague-promises-of-greener-pastures-for-migrant-workers#sthash.iHusvVN2.dpuf The informal tourism sector is growing in Sri Lanka and Hiran Cooray Chairman of the Tourist hotels of Sri Lanka for one thinks it’s a good thing.  ( see  report in the Daily Mirror )So do I.By his reckoning 2/5th of tourists coming to Sri Lanka now stay in rented apartments, villas and homestay accommodation many of which are rented out via organisations such as Homestay.com Trip Advisor, AirB&B and the like.So why is this a good thing? Let’s start with the positive side.“Tourists staying within the local communities pass the revenue directly to the bottom of the income pyramid, fast-tracking grass root level economic development.” Hiran CoorayNot everyone (Chinese apart maybe) wants to stay in an hotel. A significant number of tourists like to do their own thing, explore local areas eat when they want in and around local Sri Lankans, and so on. They don’t want to be “trapped” in a cramped and possibly quite expensive hotel room. They like the space and informality that the informal sector can offer and when you can stay in an apartment in Havelock City for example.. at a much lower cost.. well why wouldn’t you?Havelock City; example of apartmentdoing away with the negatives :So does  the hotel sector needs to worry? No of course not. Sri Lanka can offer world class tourist accommodation for those who want it; plus Colombo is set become a signicant business hub in South Asia so the growth of business tourism which depends on quality hotels is almost assured.It’s just that not every one can afford the prices that some city centre hotels charge in Colombo for example.(I could add from my experience that for the money sometimes the service could be a whole lot better, some hotel staff could be a little less “up themselves” but that is for another blog.)Where it is possible to agree with the Hotels Association is that it is not a level playing field because the informal sector are mainly unregistered and do not have to pay the tourist tax and development levy paid by the hotel chains.True but the owners do pay local and regional taxes; adding the other costs could simply cause them to raise their rentals to a level where they would not get business so thinking about applying these extra costs or banning the advertising of short term rental and homestay on the web (as has happened in New York for example) is not a step to be taken lightly.That said there is a case for regulation to be introduced in homestay and private rentals to ensure quality and value for money.In the meantime there is very little data available on the growth of the informal sector at present and maybe it would be worth conducting research so that all concerned know what it is they are discussing.So time to start asking questions;To judge by the Air B&B site much of it is in and around Colombo. If that is so then is it a bad thing? Getting more people to visit Colombo and stay for longer, not necessarily in the city centre can only be good for the economy.As I wrote in an earlier blog; A Paradise Lost ; see https://geosrilanka.wordpress.com/2015/06/16/sri-lanka-tourism-is-it-just-a-case-of-re-branding/, my belief is that Sri Lankan tourism needs a balanced portfolio of investment; homestay and apartment rentals are.   a part of that, (as is mass tourism) because it has the value of bringing tourists much closer to an understanding of Sri Lankan life and culture.After all, there is nothing better than hanging out around Water’s Edge on a Saturday night along with the thousands of families who come to chill, enjoy the street food , and relax over an affordable beer maybe.. and you don’t get to do that at The Cinnamon Grand As flood waters start to recede  they have been replaced by a different flood; the flood of blame and recrimination.  A number of journalists have been quick to lay blame in several areas, including the meteorological office, the disaster management centre and the government. However, whilst journalists and politicians wasted time looking for scapegoats others got on with a much more important job; getting help and aid to the flood victimsThe government would have it that the flood  was the result of all those poor people who built on marshland.  As a result they have said that they will be removing upwards of 2500 families from unauthorised sites; (see Sunday Times 12th June) This is either ignorance or political sophistry.“The squatter families will not be offered compensation or alternative locations, Sri Lanka Land Reclamation and Development Corporation (SLRDC) Chairmnan W.M.A.S. Iddawala told the Sunday Times. He said that in a survey carried out after last month’s devastating floods, the corporation had identified the squatter families which should be evicted.” Sunday TimesWhile some properties may have inhibited the flow of flood water in and around the cs they did not cause the flood.Building on marshland does not cause a flood. It might put people in harm’s way, but it doesn’t cause a flood to happen.The sheer volume of water falling on an unprotected catchment is what caused the flood.So why the evictions? We can only guessA good place to start is to define what vulnerable means in this context. Two aspects need to be borne in mind;Why were so many people exposed to this devastating flood and its longer term impacts? A  number of factors contributed to render the population vulnerable;Population densities in the Colombo area source: researchgateIn all more than 150,000 people were temporarily displaced by the flood. Although relatively few homes were completely lost many have suffered water damage, small shops kades and bakehouses have lost their stocks of goods to sell, livelihoods have been wrecked, many have lost all their possessions in the flood and will find it hard t replace them.This is Imi’s story. She lives with her mother and infirm grandparents in Welivita, part of Kaduwela to the north-east of the city. This is what the flood meant to families such as hers.The Disaster Management Centre should have been the body to co-ordinate flood relief efforts. However, at the height of the flood it was under 2 metres of water; not ideal. They did warn of the impending flood and they did issue evacuation alerts and to be fair other measures were put in place once the flood struck:However, good as this was there doesn’t seem to have been much coordination of the relief effort.  The President did instruct the local officials the Grama Niladahri to visit all affected areas and people in their districts to get an idea of what the problems were, and who was in most need of help but according to this Sunday Times report the response was at best patchy.and there were problems:Questions have also been raised about where all the foreign aid went because it certainly didn’t reach many of the victims if newspaper reports are to be believed. This from the Sunday Times 12th June:“Three weeks after floods ravaged many of the areas adjoining the Kelani river communities are waiting for the government machinery to move in to provide aid, rebuild houses and provide other relief. Flood victims stranded in Kelaniya, Kelanimulla and Angoda areas, this week, claimed there was no responsible officer at grassroots level to monitor the process of distributing dry rations to the destitute.”In the vacuum left by what some see as government ineptitude local volunteer groups sprung up in different districts across the city. One such group was the Welivita volunteers. Initially they came together to help their friend Imi (see above) However, they could see the need for a wider effort and within in a short time they:They did this in the space of two weeks: and you can check out their page Welivita Volunteers where you will get full details on what they did, how they did it and also a good selection of photos which graphically illustrate their work;So the point about their work was that it was:After the 2004 Tsunami the people were told that in future the government would be ready; those scenes of chaos in 2004 could not happen again..that does not seem to be the case. Looking through recent newspaper articles it would seem that the government effort raises more questions than answers;After events like this one governments all over the world (certainly in the UK) drone on about lessons to be learned.. evidence is that those lessons are rarely learned. However, there are some take away points:There are two stages to a flood event like this:Initially the need is for search and rescue; the military are best placed to do this; I suspect that if they had been in charge the rescue operation would have been properly coordinated and way more efficient. They have the helicopters to overfly flooded areas and provide first hand intelligence to direct the rescue effort plus they have a command network that would be effective in these situationsOne thing is for sure; the river will flood again whether people are living on marshland or not. The question as ever, is will the government be ready? In Sri Lanka large hydro power potential has been fully utilised. There is no space to add in more plus the existing schemes are multi purpose, providing necessary irrigation water especially to the semi dry and dry zones. And this places a further limit on the capacity of Sri Lanka to generate additional electricity from major H.E.P. schemesHowever, there are opportunities for the development of privately owned small scale or mini hydro schemes which could add power to the national grid in Sri Lanka. The problem is that  these schemes are causing concern amongst environmentalists because they block streams and threaten the environment of fresh water fish and fragile riverine ecosystems.The Sri Lankan government has ambitious plans to achieve high rates of economic growth in the coming years. However, Sri Lanka barely generates enough energy to satisfy the demands both domestic and industrial right now. To make matters worse, existing power supply has been plagued by disruptions and power outages in the last few months.Since coming online the thermal power station at Norochalai on the east coast has had several reported breakdowns including a fire, a leak, a trip and an instance where generation exceeded design levels, causing a shutdown. The most recent shutdown came in March when an explosion in a stepdown transformer caused an island-wide power outage.It doesn’t help levels of confidence in the electricity generation system to read Sri Lanka’s deputy minister for power and renewable energy, Ajith Perera, saying that the plant had been built with “outdated” technologies and substandard materials.Add in the continuing debate over whether the next thermal power station at Sampur should be built and it  is understandable that the authorities would consider  additions to the grid from  privately owned hydro electric power generation which is both clean and renewable.A mini hydro project works by having water in a river diverted to a powerhouse by means of a dam built across the flow. This water rotates a turbine and flows back downstream. Not all the water can be diverted: a part has to be let flow naturally in the river, according to law.reprinted with permission by Malaka Rodrigoreprinted with permission by Malaka RodrigoThe advantages to the state seem obvious.However, this form of clean energy comes at a cost;Add to that the question of whether the state should be reliant on private companies for additional power generation when their  main motive in building these schemes is arguably profit above any other consideration, including the environmentSome tea estates up in the hills already operate their own private schemes providing power to the tea factories. Theses schemes are generally not taking place in environmentally sensitive areas and are not the focus of this article. What is of concern is applications to develop mini hydro schemes in environmentally sensitive areas such the Sinharaja rainforest reserve.The proposal to build a  mini hydro plant at a waterfall and beauty spot is posing a real threat to Athwelthota river; home to 39 freshwater species 19 of them endemic to Sri Lanka.source YoutubeThe Athwelthota is one of many rivers that flows out from the northern flanks of the Sinharaja rain forest reserve in southern Sri Lanka. Sinharaja is a world heritage site, and the country’s last viable area of primary tropical rainforest. More than 60% of the trees are endemic and many of them are considered rare. There is much endemic wildlife, especially birds, but the reserve is also home to over 50% of Sri Lanka’s endemic species of mammals and butterflies, as well as many kinds of insects, reptiles and rare amphibians.source Google sitesAthwelthota is a paradise for freshwater fish, with a number of species discovered in this unique habitat. The CEJ and the Wildlife Conservation Society of Galle (WCSG) have published a poster showing the indigenous fish that could be endangered by the proposed mini-hydro project in Pilithudu ella, Morapitiya-Athwelthota.If a mini hydro plant is built, some believe that  the change in flow will be a death sentence for many species living in this micro-habitat,In Athwelthota, 39 freshwater species have been recorded, 20 of them endemic to Sri Lanka.Most of the mini-hydro projects are being constructed in the biodiversity rich wet zone, so the damage they cause is actually worse than with the large dams,  Not only the fish but other animals such as amphibians and freshwater crabs too are affected.Athwelthota is also home to Sri Lanka’s only aquatic orchid. Near a waterfall lies a special “spray zone” full of water vapour and this special habitat could be totally lost,Overall 37 projects are under consideration/construction; many in or on the boundaries of the Sinharaja Rain Forest Reserve.Construction is being carried out in the Northern Sinharaja Rainforest buffer zone at Kosgulana, approximately 4km east from the Kudawa main entrance. A dam is being built blocking the Kosgulana river in Sinharaja buffer zone and several acres of rainforest have been cleared and concrete laid along the once pristine and protected riverbank. Large trucks and machinery used for construction have driven a wide track through what was once a small footpath in the Sinharaja buffer zone, between Kudawa and Kosgulana,Another project in the rain forest where 2.5km of concrete penstock has been constructed in the Dellawa district is also said to be “causing massive environmental destruction to the stream, the wildlife and the forest The mini-hydro project will destroy a total 6.5 km stretch of the Anda Dola as water is being diverted from the weir to the powerhouse, several kilometres away. This will result in the local extinction of many endemic and endangered fish species recorded in the Anda Dola.and what impact might this have on tourism going forward.. not everyone wants to dump themselves on a beach for two weeks…Sri Lanka as a country is changing. With the new government there is a greater concern for the environment and a growing resistance on the part of environmentalists to the power of local politicians and businessmen who have been allowed to ignore the environmental laws of the country. It will be interesting to see how successful they are going forward.In any case micro hydro schemes are not the answer to Sari Lanka’s growing energy problem. Put together they will not generate the additional power needed. Neither can the island continue to afford to import large amounts of oil to generate power.Maybe that does mean going ahead with the Sampur coal fired power station in spite of all the objections. Or maybe the government and its foreign funding partners should be looking much more seriously at wind power and solar power as alternatives rather than dumping outmoded and dirty technology on an unsuspecting population.Acknowledgement: I am grateful, as ever, to Malaka Rodrigo for allowing me to take much of the above from his excellent article: Mini hydros; clean energy comes at a high cost to nature featured in his blog: Window to NatureYou should also read his latest blog which is a follow u on the first one athttp://www.sundaytimes.lk/160828/news/flawed-approvals-of-mini-hydro-projects-spell-river-land-destruction-206573.html photo: Hinimama; a local farmer on the edge of Uduwalawe national parkSri Lanka is a unique place to visit for A level field work in Geography, Development Studies and Environmental Studies, even History and Archaeology There is so much to see and do.you can get a clue from the range of articles in the blog, but these are just the first that come to mind; you can get site visits and talks for all of them with a bit of help.On top of that there is also the possibility to add in some more “touristy” stuff; A walk in the Cloud Forest of Horton Plains, the train ride from Colombo to Ella, an elephant safari, tea plantations and a climb up on to Sigiriya.I accompanied my old school, The Sixth Form College, Colchester on highly successful trips in 2014 and 2015..and in fact ended up doing a large part of the organising and teaching.Each student will need an entry visa which they buy themselves online for approx. $35Arranging tours abroad is always challenging but we found  hotels and other organisations in Sri Lanka to be really very efficient and very helpful.
