Chronological and Administrative/Legal History

There has been a long-drawn-out legislative battle between the government bureaucracy and politically influential cultivators of seasonal cash crops over the Maha Kudugala Apple Farm lands since its opening up in the 1970s. A total extent of 126 ha consisting of three land blocks each of 89 ha, 12 ha, and 5 ha respectively, is located entirely within the upper-most watershed mainly of Kurundu Oya in the Maha Kudugala GN Division of the Pidurutalagala (Pedro) Conservation Forest. The elevational range in the cultivation area is 1500 m – 2100 m (over 5000 ft.) having steep slopes mostly over 60o, (See Figure 1)

This land is also located within the ‘Central Environmental Fragile Area’ (a geographic entity that consists of the lands with sensitive natural ecosystems highly vulnerable to landslides which play a crucial role in sustaining water resources) depicted in the 2008-2030 National Physical Policy Plan and also in its updated version of 2017-2050 (Govt. Gazette No. 2127/15 – 12 June 2019).

The earliest records indicate that this land has been included in a forest area that has been declared way back in 1938 as state land for which survey plans were subsequently drawn up in 1942. The forest range was designated in this survey plan as Kurundu Oya Mukalana – the primary watershed forest of the Kurundu Oya. This 1942 survey plan refers to the entire forest range as a Climate Reserve for the protection of the sources and courses of streams arising from this forest area’ (FSPP 84B and 84C in the survey plan) highlighting its importance in watershed protection even at that time. It was later designated as Maha Kudugala Proposed Forest Reserve and included as a part of the Pidurutalagala Proposed Reserve according to the Forest Conservation Act which was resurveyed in 2004 and declared as a Conservation Forest by the Gazette No: 1527/22 on 14 Dec. 2007.

Cultivation History

Upon a request by the Nuwara Eliya District Co-ordinating Committee made on 08 Oct. 1970, the Forest Department had apparently issued a ‘no objection’ letter dated 11 Dec. 1970 to release 300 acres of this forested state land on the basis of a long-term lease in Maha Kudugala Proposed Forest Reserve for the cultivation of apple trees as a co-operative project to 97 members of the Ragala/Walapane Apple Growers’ Co-operative Society. However, these cultivators not only deviated from the original agreement to grow apple trees but also had not paid the annual lease for the land blocks leased out to them over several years. Consequently, upon a recommendation by the Forest Department, the then Secretary, Ministry of Lands and Land Development issued a directive on 23 March 1978 to the Government Agent/Nuwara Eliya to transfer back the entire land area to the Forest Department for reforestation. Since these directives were apparently not honoured by the apple farm cultivators, the issue has gone no less than to the highest legislative/executive authority – the President of the country.

The then HE President issued a directive in June 1990, approving the recommendations made by the Secretary, Ministry of Lands, Irrigation and Mahaweli Development on 14 May 1990 that all the occupants of the apple farm land (the members of the Ragala/Walapane Apple Growers’ Co-operative Society) to be evicted for deviating from the specific cultivation practices for which the land was originally leased out namely, for the cultivation of apple trees, thus causing extensive damage to this fragile landscape. The land to be reclaimed was once again recommended to be reforested.

However, the members of the apple growers’ co-op society (those with LDO permits as well as those who have established their long-term residence in the area) moved the Court of Appeal that the quit notice issued by the DFO, Nuwara Eliya in 1992 and the related actions pending in the Magistrate Court at Walapane be quashed. However, the Appeal Court issued the judgment on 20 Sept 2016 that the eviction order issued in 1992 is a legally valid document and that all ten notices requesting the repeal of the DFO order be annulled.

A second application submitted by 40 petitioners – all occupants of the said land, seeking to quash the Notice to Quit dated 31 Dec. 1992 issued by the Forest Department under Section 3 of the State Lands (Recovery of Possession) Act No. 7 of 1979 (as amended later), by way of Writ of certiorari was also dismissed (but without costs), at the Court of Appeal on 02 Dec. 2019 as the lands were initially released to promote apple cultivation, and that too not forever. During the delivery of the above judgment by the Appeal Court Judge in 2019 (CA Case No: CA/WRIT/6/2015) the statement made in their submission by the Forest Department that ‘the lands are situated over 5000 ft. altitude and part of the catchment area of the Randenigala Reservoir and the illegal occupation and the cultivation of the said area by unauthorised occupants including the petitioner by using hazardous chemicals severely affect the biodiversity of the entire conservation forest and cause siltation in the Randenigala reservoir’ was quoted in the Judgement statement thus under-scoring the conservation value of this forest landscape. (See Figure 2)

Conservation value of the Maha Kudugala Forest in the Pidurutalagala Range

The NE-facing upper montane rain forests are part of a separate plant geographic unit known as the Montane Intermediate Floristic Region (G1) which was recognised recently during the preparation of the 6th National Report for the Convention on Biological Diversity. These forests are among the most threatened landscapes within Sri Lanka for their exceptionally rich biodiversity and critical ecosystem services such as watershed and soil conservation functions they perform. In the pre-colonial era, these forest-clad landscapes provided year-round water security to the traditional rural communities of the present-day Walapane and Hanguranketha Divisional Secretariats lying in the eastern escarpments of the central highlands.

IV. Watershed Value

In terms of hydrological importance, the Pidurutalagala (Pedro) reserve was ranked number three (no. 3), just behind the Peak Wilderness and the Knuckles range, out of all the natural forests in Sri Lanka surveyed during the National Conservation Review (NCR 1996) conducted by the IUCN-The World Conservation Union with funding from the FAO. The main reason for gaining such a high rank is the contribution of fog interception by the natural forests to feed the streams originating from the forests thus ensuring year-round water security. According to the methodology used in the IUCN-sponsored NCR (1996), the horizontal precipitation by way of fog interception that feeds the streams foregone by converting forest into agricultural land use is about 860,000 cubic meters per annum (Personal communication by Prof. Nimal Gunawardena).

This is a substantial quantity of water in view of the issues currently faced by the Walapane Water Supply Scheme located downstream and the farmers who have been using the stream water of the Kurundu Oya for their subsistence for generations. Therefore, leaving the forests in the upper catchments is very important to regulate the stream flow since studies have shown that the fog contribution is significant, especially during the dry season. The NCR survey further indicated that there are 13 streamlets fed by the area covered specifically by the apple farm area and the lack of natural forest cover seriously affects the regulation of stream flow, which normally controls flash floods, soil erosion, and landslides.

One of the most harmful consequences of converting forests into intensive vegetable cultivation is the on-farm soil erosion and sedimentation of downstream reservoirs. The field studies in Nuwara Eliya district have shown that the soil erosion from intensive cultivation is about 100 t/ha/year whereas the soil erosion from the natural forest is as low as 0.3 t/ha/year. Almost all of such eroded soil released to the Kurundu Oya from the Apple Farm area ends up in the Randenigala Reservoir since there is a very steep gradient along the Kurundu Oya. This high level of soil erosion also increases the water purification cost at the Walapane Water Supply scheme due to the increased expense for chemicals to remove sediments from water and operate the pumps to flush out sediments from the filters at frequent intervals.

Heavy inputs of inorganic fertiliser, pesticides, and weedicides in vegetable and other cash crop cultivation in this area contaminate both surface- as well as ground-water thus affecting the drinking water quality of the downstream communities.

A land use management plan (still in the draft stage) prepared by the LUPPD/Ministry of Environment and Wildlife Resources (MEWR) under a UNDP/World Food Programme funded project titled ‘Addressing Climate Change Impacts on Marginalised Agricultural Communities Living in the Mahaweli River Basin” (https://docs.wfp.org/api/documents/WFP-0000128802/download/), has identified and classified 297 water sources in Walapane DS Division fed by the three streams – Beliul-, Kurundu-, Halgan Oya into three water quality classes [Class 1 (127 – good), II (114 – fair), and III (26 – poor)]. This report strongly recommends that it is crucial to maintain a suitable land cover (tree-dominated), particularly on the higher slopes to reduce the runoff by increasing infiltration and minimising soil erosion. The UNDP report further recommends that the home gardens with seasonal cash crop cultivation in the slopes over 60% in the Walapane DSD need to be relocated, if possible. Alternatively, cultivation of these seasonal crops (vegetables and potatoes) should not be permitted in these home gardens and their land cover needs to be improved considerably by introducing tree crops (agroforestry practices) with intensive conservation measures. Since the Apple Farmlands are located further up in the watersheds of the three streams (Fig. 2 map on the right), the same evidence-based recommendations given in this report are applicable to them as well.

Biodiversity Value:

A recent biodiversity sensitivity ranking analysis conducted by University-based researchers using eight taxonomic groups namely, mammals, birds, reptiles, amphibians, freshwater fish, dragonflies and damselflies, butterflies, and land snails has clearly identified the Kurundu Oya Mukalana that includes the Apple Farm area harbor a high concentration of endemic and range-restricted fauna See Fig. 3 below.

V. Impact on National Commitments to Global Conventions:

As a signatory to the three Rio Conventions (UNFCCC, UNCBD, and UNCCD), Sri Lanka is under obligation to achieve the national conservation targets within a set time frame (by 2030). Among these are i) restore and improve degraded forests (80% in the Dry Zone and 20% in the Wet Zone) ii) Increase the forest cover from 29% to 32% iii) Reduce the rate of soil degradation to improve land productivity and Soil Organic Carbon (SOC) stocks and iv) reduce soil erosion of lands cultivated with annual and plantation crops.

Under the UNCCD, the Sri Lankan Government has reaffirmed its commitment to Sustainable Development Goals (SDG) 15 and Target 15.3 and participated in the Land Degradation Neutrality Target setting Programme (LDN-TSP) to identify national targets. (file:///E:/CP-%20SAM%20-%20Ch.%203%20_%20Montane%20zone/Apple%20Farm/Sri%20Lanka%20LDN%20Country%20Commitments.pdf). Among the Land Degradation Neutrality (LND) measures identified as national priorities, the following measures listed in the LDN national report (Box 3 on page 7) are directly relevant to the Apple Farm issue.

Change the policy of regularising the encroachment of state lands,

Halt the cultivation of annual crops in steep lands and facilitate the conversion of such lands to perennial crops,

Encourage the adaptation of sustainable management practices through incentives.

Summary

In summary, the above-detailed review of both scientific and legal evidence along with the nationally pledged commitments to the three international conventions (UNCBD, UNFCCC, and UNCCD), unequivocally underscores the fact that the current land use practices in the Apple Farm lands are being carried out in violation of National Policies and Legislation (National Physical Policy Plan, Forest Conservation Act, Soil Conservation Act, National Policy on Protection and Conservation of Water Sources, their Catchments and Reservations in Sri Lanka [2014]) and also contravening the legally binding international commitments made to the three Rio Conventions that Sri Lanka is a signatory to.

At present Sri Lanka is moving towards a green economic environment encouraging investments for sustainable and transformative green development projects addressing the nationally important sustainability issues viz. rapid loss of biodiversity, impacts of accelerated land degradation compounded by changing climate, especially on the critical upper watersheds of major river basins.

In such a situation, the current state of affairs on the Apple Farm Land issue creates serious precedence in environmental and social mismanagement and misgovernment, thus severely impacting our national drive toward achieving Sustainable Development Goals by 2030 and Land Degradation Neutrality targets through green economic pathways during this Decade of Forest Restoration (2021-2030).

Iain Douglas-Hamilton: Science, courage, and the battle for elephants

Published

on

Iain Douglas-Hamilton

Passing of Iain Douglas-Hamilton, a man who dedicated his life to conservation and whose life’s work leaves a lasting impact on our appreciation for, and understanding of, elephants.

– Prince William

In Africa on 08 December, 2025, when the sun slipped below the horizon, it did not only give an end for that day, but it also marked the end of a man whose knowledge and courage saved Africa’s elephants. This gentleman was none other than Iain Douglas-Hamilton! There is a beautiful African proverb that says, “When an old man dies, a library burns to the ground,” and it resonates well with Iain’s demise.

Iain pioneered behaviour research on elephants, and he was the first to highlight the elephant poaching crisis in Africa. Also, the adventures he went through to save the elephants will inspire generations.

From Oxford to Africa

The Life of the Last Proboscideans: Elephants”, authored by Muthukumarana, stands as an awardwinning, comprehensive study that integrates elephant evolution, anthropology, biology, behaviour, and conservation science.

Iain was born on 16 August, 1942, into an aristocratic family, the son of Lord David Douglas-Hamilton and Ann Prunella Stack. His parents were a distinguished couple in Britain: his father, a Scottish nobleman, served as a squadron leader in the Royal Air Force, while his mother was a pioneering figure in physical fitness and a prominent advocate for women’s rights. After finishing his school, Iain was admitted to Oxford University to study zoology. At the age of 23, for his PhD, Iain travelled to Tanzania to study the behaviour of elephants at Lake Manyara National Park. This was a daring and humble beginning that would change how the world understood elephants. He learnt to recognise individual animals based on their tusks and ears. He observed their family bonds, their grief, and their intelligence. These findings made the scientific community identify elephants as sentimental beings. During this period, he married Oria Rocco, and together they had two children, Saba and Mara.

Battle for the elephants

When ivory poaching swept across Africa and devastated elephant populations, Iain did not withdraw in despair. He confronted the crisis head-on, guided by science, rigorous data, and unwavering resolve. Through extensive aerial counts and field studies, he laid bare the scale of the tragedy—revealing that Africa’s elephant numbers had collapsed from an estimated 1.3 million to just about 600,000 in little more than 10 years.

It was largely thanks to his work that the global community saw—perhaps for the first time—the full scope of the crisis. His efforts played a pivotal role in pushing forward the 1989 international ban on ivory trade, a landmark moment for wildlife conservation.

In 1993, Iain founded Save the Elephants (STE), an organisation that would become the heart of elephant conservation efforts in Kenya and across Africa.

At STE, he pioneered the use of GPS-tracking and aerial survey techniques to monitor elephant movements, protect them from poaching, and plan safe corridors for them in increasingly human-dominated landscapes. These methods have since become standard tools in wildlife conservation worldwide.

Beyond technology and science, Iain was a mentor. He inspired — and continues to inspire — generations of conservationists, researchers, and everyday people who care deeply about wildlife. Through his books (such as Among the Elephants and Battle for the Elephants), documentaries, lectures, and personal example, he invited the world to see elephants not as trophies or commodities, but as sentient beings — worthy of awe, study, and protection.

Iain and Sri Lanka

In 2003 Iain came to Sri Lanka for the first time to attend the “Symposium on Human-Elephant Relationships and Conflict” as the keynote speaker. On that day he concluded his address by saying, “When I hear the talk of Problem Animal Control, I always wonder whether our species has the capacity for its own self-regulation or Problem Human Control in a humane and wise manner. HEC stands for Human Elephant Conflict, one of our focuses of this conference. How I wish it could come to stand for Human Elephant Coexistence, based on a recognition that other beings also need their space to live in. We are a long way from that, but I am sure that many of the findings of the talented body of researchers in this room will begin a stepwise progress in answering some of these fundamental problems.”

A few years ago Iain’s organisation STE collaborated with the Sri Lankan Wildlife Conservation Society for research activities aimed at reducing human-elephant conflict. In 2016 when the Sri Lankan government was going to destroy the confiscated illegal African elephant ivory, I made a request for Iain to write a congratulatory message to Sri Lanka’s President and Prime Minister for the wise decision they had taken. Iain sent me a four-page meaningful letter written by him, and he was joined by 18 other conservation organisations. In his letter he mentioned, “I want to offer my congratulations to the government of Sri Lanka for the laudable decision to destroy ivory stocks…” Sri Lanka is sending a message to the world that ivory should be without worth; elephants have value when alive. This is a critical message to send, particularly to the religious world, as they are sensitised about the threat religious ivory poses to elephant populations in Africa.”

Fortunately, Iain’s conservation is taken up by his children, especially his eldest daughter, Saba. In 2016 and 2024 she came to Sri Lanka for a lecture hosted by the Galle Literary Festival. Also in 2019, for the Wildlife and Nature Protection Society’s 125th Anniversary, Saba and her husband visited a gala dinner that was held to fundraise for conservation projects.

A difficult path

Iain’s path was never easy. He endured personal peril many times: from hostile terrain and unpredictable wild animals to being shot at by poachers while conducting aerial patrols over war-torn national parks.

Yet despite the danger, despite setbacks — flooded camps, lost data, shifting political tides — his conviction never wavered. His was a life marked by resilience. He refused complacency. He refused to surrender. And through every hardship, he remembered why he began: to give elephants a future.

Iain was also a pilot, and as the old English saying goes, “Pilots don’t die; they simply fly higher.” In that spirit, I wish the same peaceful ascent for Iain. My heartfelt condolences are with Iain’s family.

Awesome power of gratitude

Published

on

When you hear the word gratitude the first impression you get is a tail-wagging dog. If you feed a dog one day, it will wag its tail even if you meet it after a few years. That is gratitude. In addition, dogs are great teachers. They are at home in the world. They live in the moment and they force us to stay with them. Dogs love us and remain grateful unconditionally not for our bodies or bank accounts.

Small children are taught to say ‘Thank you’ for any favour they receive from others. They do not know that the two words can have positive effects on your health and the well-being of others.

Some time ago I had to call emergency services as I found one of my family members was unconscious. Within minutes an ambulance arrived and the paramedics whisked the patient away to the nearest hospital. He was in intensive care for a few days and returned home. We were marvelled at the impact of a handful of strangers who took charge of the patient at a critical time. I immediately wrote thank you notes to those who saved the patient’s life. I knew that it was a small gesture on my part. However, it was the only way I could express my gratitude to a dedicated team.

Selfless people

Later I realized that there are a large number of selfless people who do life-saving work, but they never expect anything in return. How volunteers saved a large number of flood victims is a case in point. The flood victims may not have expressed their gratitude in so many words. However, they would have felt a deep sense of gratitude to the volunteers who saved them.

Why do people come forward to help those facing natural disasters and other dangerous situations? A recent research in the United States shows that sharing thoughts of gratitude and performing acts of kindness can boost your mood and have other positive effects on your health. Almost all religions teach that gratitude does have a good impact on your happiness. Professor of Psychology Willibald Ruch says that gratitude is among the top five predictors of happiness.

By showing gratitude you can make positive changes in your own life. If you feel a sense of gratitude whenever you receive something that is good for you, it will be a healthy sign. You cannot get such a feeling in a vacuum because others have to play their roles. They can be your loved ones, friends, strangers or even people in authority. Gratitude is how you relate to them when you see yourself in connection with things larger than yourself.

Gratification lifestyle

Strangely, many people do not pause to appreciate what others are doing for them. For this you have to blame your gratification lifestyle. With the popularity of social media the young people feel that they are the centre of the universe. They seem to think there is no necessity to thank those who help them.

Why should we thank others even for minor favours? Recent studies show that those who express gratitude increase their own happiness levels. They also lower their blood pressure levels to a great extent. On the other hand, they will be able to sleep well and improve their relationships. They are also less affected by pain because of the positive impact on their depression.

They may not know that positive effects of gratitude are long lasting. Research shows that those who write thank you notes improve their mental health. There was also a decrease in their bodily pains. What is more, they feel more energetic in completing their daily activities. Unfortunately, schools and universities do not teach the value of gratitude since it is fairly a new field of study. Researchers are still trying to find out its cause and effect relationship. We know that those who perform acts of gratitude can sleep well. However, we do not know the reason for it. Researchers are wondering whether gratitude leads to better sleep or sleep leads to more gratitude. They also probe whether there is another variable that leads to gratitude and improved sleep.

Children

Despite such controversies, we know for certain that gratitude can benefit people at any stage of life. Most elderly people remain grateful for their children and grandchildren who support them. Elderly people cannot regain their physical strength or mental agility. Therefore they focus on gratitude. They are thankful to their children and grandchildren for their present situation.

How do gratitude recipients react? Research shows that those who receive thank you notes or acts of kindness experience positive emotions. You feel happy when someone holds a door open for you. Similarly, you are happy if you receive some unexpected help. Recently I was pleasantly surprised to see that someone has credited a big sum of money to my bank account in appreciation of a small favour I had done.

When you thank someone they are more likely to return the favour or pay kindness forward. Psychologically, people feel very happy when you thank them. However, some people hesitate to say thank you. The give-and-take of gratitude deepens relationships. In a close relationship husbands and wives do not thank each other. However, there are other ways of showing gratitude. A wife can make her husband feel appreciated. Such a feeling of appreciation will go a long way to strengthen their relationship.

Some people are ungrateful by nature. However, they can learn the art of being grateful. Such people will do well to maintain a gratitude journal. It is something similar to Pinpotha maintained by Buddhists in the past. They can record positive events in the journal. At the beginning this may not be easy. With practice, however, you can do it well. I knew of a man who kept a gratitude journal. Although his family members laughed at him, he did not give up the habit. When he was diagnosed with a terminal disease he used to read his gratitude journal very happily.

Another Christmas, Another Disaster, Another Recovery Mountain to Climb

Published

on

In line with its overall response to Cyclone Ditwah that devastated many parts of Sri Lanka, India has undertaken to set up temporary Bailey Bridges at selected locations. Work on the first such bridge has begun in Kilinochchi on the Paranthan–Karaichi–Mullaitivu A35 road. Indian Army engineers are working with their counterparts. The Indian HC said that 185 tonnes of Bailey Bridge units were airlifted to restore critical connectivity, along with 44 engineers (Pic courtesy IHC)

The 2004 Asian Tsunami erupted the day after Christmas. Like the Boxing Day Test Match in Brisbane, it was a boxing day bolt for Indonesia, Thailand, Sri Lanka, India and Maldives. Twenty one years later, in 2025, multiple Asian cyclones hit almost all the old victims and added a few more, including Malayasia, Vietnam and Cambodia. Indonesia and Sri Lanka were hit hard both times. Unlike the 2004 Tsunami, the 2025 cyclones made landfalls weeks before Christmas, during the Christian Season of Advent, the four-week period before Christmas preparing for the arrival of the Messiah. An ominously adventus manifestation of the nature’s fury.

Yet it was not the “day of wrath and doom impending … heaven and earth in ashes ending” – heavenly punishment for government lying, as an opposition politician ignorantly asserted. By that token, the gods must have opted to punish half a dozen other Asian countries for the NPP government’s lying in Sri Lanka. Or all those governments have been caught lying. Everyone is caught and punished for lying, except the world’s Commander in Chief for lying – Donald J. Trump. But as of late and none too sooner, President Trump is getting his punishment in spades. Who would have thought?

In fairness, even the Catholic Church has banished its old hymn of wrath (Dies irae, dies illa) that used to be sung at funerals from its current Missals; and it has on offer, many other hymns of peace and joy, especially befitting the Christmas season. Although this year’s Christmas comes after weeks of havoc caused by cyclonic storms and torrential rains, the spirit of the season, both in its religious and secular senses, will hopefully provide some solace for those still suffering and some optimism to everyone who is trying to uplift the country from its overflowing waterways and sliding slopes.

As the scale of devastation goes, no natural disaster likely will surpass the human fatalities that the 2004 Tsunami caused. But the spread and scale of this year’s cyclone destruction, especially the destruction of the island’s land-forms and its infrastructure assets, are, in my view, quite unprecedented. The scale of the disaster would finally seem to have sunk into the nation’s political skulls after a few weeks of cacophonic howlers – asking who knew and did what and when. The quest for instant solutions and the insistence that the government should somehow find them immediately are no longer as vehement and voluble as they were when they first emerged.

NBRO and Landslides

But there is understandable frustration and even fear all around, including among government ministers. To wit, the reported frustration of Agriculture Minister K.D. Lalkantha at the alleged inability of the National Building Research Organization (NBRO) to provide more specific directions in landslide warnings instead of issuing blanket ‘Level 3 Red Alerts’ covering whole administrative divisions in the Central Province, especially in the Kandy District. “We can’t relocate all 20 divisional secretariats” in the Kandy District, the Minister told the media a few weeks ago. His frustration is understandable, but expecting NBRO to provide political leaders with precise locations and certainty of landslides or no landslides is a tall ask and the task is fraught with many challenges.

In fairness to NBRO and its Engineers, their competence and their responses to the current calamity have been very impressive. It is not the fault of the NBRO that local disasters could not be prevented, and people could not be warned sufficiently in advance to evacuate and avoid being at the epicentre of landslides. The intensity of landslides this year is really a function of the intensity and persistence of rainfall this season, for the occurrence of landslides in Sri Lanka is very directly co-related to the amount of rainfall. The rainfall during this disaster season has been simply relentless.

Evacuation, the ready remedy, is easier said than socially and politically done. Minister Lal Kantha was exasperated at the prospect of evacuating whole divisional secretariats. This was after multiple landslides and the tragedies and disasters they caused. Imagine anybody seriously listening to NBRO’s pleas or warnings to evacuate before any drop of rainwater has fallen, not to mention a single landslide. Ignoring weather warnings is not peculiar to Sri Lanka, but a universal trait of social inertia.

I just lauded NBRO’s competence and expertise. That is because of the excellent database the NBRO professionals have compiled, delineating landslide zones and demarcating them based on their vulnerability for slope failure. They have also identified the main factors causing landslides, undertaken slope stabilization measures where feasible, and developed preventative and mitigative measures to deal with landslide occurrences.

The NBRO has been around since the 1980s, when its pioneers supplemented the work of Prof. Thurairajah at Peradeniya E’Fac in studying the Hantana hill slopes where the NHDA was undertaking a large housing scheme. As someone who was involved in the Hantana project, I have often thought that the initiation of the NBRO could be deemed one of the positive legacies of then Housing Ministry Secretary R. Paskaralingam.

Be that as it may, the NBRO it has been tracking and analyzing landslides in Sri Lanka for nearly three decades, and would seem to have come of age in landslides expertise with its work following 2016 Aranayake Landslide Disaster in the Kegalle District. Technically, the Aranayake disaster is a remarkable phenomenon and it is known as a “rain-induced rapid long-travelling landslide” (RRLL). In Kegalle the 2016 RRLL carried “a fluidized landslide mass over a distance of 2 km” and caused the death of 125 people. International technical collaboration following the disaster produced significant research work and the start of a five-year research project (from 2020) in partnership with the International Consortium on Landslides (ICL). The main purpose of the project is to improve on the early warning systems that NBRO has been developing and using since 2007.

Sri Lankan landslides are rain induced and occur in hilly and mountainous areas where there is rapid weathering of rock into surface soil deposits. Landslide locations are invariably in the wet zone of the country, in 13 districts, in six provinces (viz., the Central, Sabaragamuwa, Uva, Northwestern, Western and Southern, provinces). The Figure below (from NBRO’s literature) shows the number of landslides and fatalities every year between 2003 and 2021.

Based on the graphics shown, there would have been about 5,000 landslides and slope failures with nearly 1,000 deaths over 19 years between 2003 and 2021. Every year there was some landslide or slope failure activity. One notable feature is that there have been more deaths with fewer landslides and vice-versa in particular years. In 2018, there were no deaths when the highest number (1,250) of landslides and slope failures occurred that year. Although the largest number in an year, the landslides in 2018 could have been minor and occurred in unpopulated areas. The reasons for more deaths in, say, 2016 (150) or 2017 (250+), could be their location, population density and the severity of specific landslides.

NBRO’s landslide early warning system is based on three components: (1) Predicting rainfall intensity and monitoring water pressure build up in landslide areas; (2) Monitoring and observing signs of soil movement and slope instability in vulnerable areas; and (3) Communicating landslide risk level and appropriate warning to civil authorities and the local public. The general warnings to Watch (Yellow), be Alert (Brown), or Evacuate (Red) are respectively based on the anticipated rainfall intensities, viz., 75 mm/day, 100 mm/day; and 150 mm/day or 100 mm/hr. My understanding is that over the years, NBRO has established its local presence in vulnerable areas to better communicate with the local population the risk levels and timely action.

Besides Landslides

This year, the rain has been relentless with short-term intensities often exceeding the once per 100-year rainfall. This is now a fact of life in the era of climate change. Added to this was cyclone Ditwah and its unique meteorology and trajectory – from south to north rather than northeast to southwest. The cyclone started with a disturbance southwest of Sri Lanka in the Arabian Sea, traversed around the southern coast from west to east to southeast in the Bay of Bengal, and then cut a wide swath from south to north through the entire easterly half of the island. The origin and the trajectory of the cyclone are also attributed to climate change and changes in the Arabian Sea. The upshot again is unpredictability.

Besides landslides, the rainfall this season has inundated and impacted practically every watershed in the country, literally sweeping away roads, bridges, tanks, canals, and small dams in their hundreds or several hundreds. The longitudinal sinking of the Colombo-Kandy Road in the Kadugannawa area seems quite unparalleled and this may not be the only location that such a shearing may have occurred. The damages are so extensive and it is beyond Sri Lanka’s capacity, and the single-term capacity of any government, to undertake systematic rebuilding of the damaged and washed-off infrastructure.

The government has its work cutout at least in three areas of immediate restoration and long term prevention. On landslides warning, it would seem NBRO has the technical capacity to do what it needs to do, and what seems to be missing is a system of multi-pronged and continuous engagement between the technical experts, on the one hand, and the political and administrative powers as well as local population and institutions, on the other. Such an arrangement is warranted because the landslide problem is severe, significant and it not going to go away now or ever.

Such an engagement will also provide for the technical awareness of the problem, its mitigation and the prevention of serious fallouts. A restructuring could start from the assignment of ministerial responsibilities, and giving NBRO experts constant presence at the highest level of decision making. The engagement should extend down the pyramid to involve every level of administration, including schools and civil society organizations at the local level.

As for external resources, several Asian countries, with India being the closest, are already engaged in multiple ways. It is up to the government to co-ordinate and deploy these friendly resources for maximum results. Sri Lanka is already teamed with India for meteorological monitoring and forecasting, and with Japan for landslide research and studies. These collaborations will obviously continue but they should be focused to fill gaps in climate predictions, and to enhance local level monitoring and prevention of landslides.

To deal with the restoration of the damaged infrastructure in multiple watershed areas, the government may want to revisit the Accelerated Mahaweli Scheme for an approach to deal with the current crisis. The genesis and implementation of that scheme involved as many flaws as it produced benefits, but what might be relevant here is to approach the different countries who were involved in funding and building the different Mahaweli headworks and downstream projects. Australia, Britain, Canada, China, Italy, Japan, Sweden and Germany are some of the countries that were involved in the old Mahaweli projects. They could be approached for technical and financial assistance to restore the damaged infrastructure pieces in the respective watershed areas where these countries were involved.
