Quota system to manage water under large-scale irrigation projects

By Mahinda Panapitiya
One of the issues faced by the farmers in areas under the large-scale irrigation projects in Sri Lanka is the water scarcity due to unexpected droughts during cultivation seasons as is the case in the areas under Uda-Walawe, Kala Wewa reservoirs, etc. When this type of situations happens in a country like Sri Lanka, where there is no clearly defined water policy for allocating water for different purposes, the only way to address is the mobilisation of water users to save available water. The main purpose of this article is to explain an approach called Water Quota (WQ) introduced in 2000 in System H under Kal Wewa reservoir to address this type of situations. Explained below is how that approach was implemented under Kala Wewa reservoir in 2000.
Water Quota (WQ) approach
The main objective of the WQ approach was to create a constantly updated Volumetric Awareness among Farmer Organisations under each Distributary Canals (DCFOs) of the water availability in the main reservoir located far away from their farms. For updating, display boards were fixed along the Main Canals (as shown in photo) at the head of each Distributary Canals (DCs) originating from the main canals.
Because of this awareness, each Distributary Canal Farmer Organizations (DCFOs) knew how many gallons (Cubic Metres) of water would be available in the main reservoir for the rest of the cultivation season. For an example, under a project called the Mahaweli Restructuring & Rehabilitation Project (MRRP) launched in 2000 in Kala Wewa area, about 40 such Display Boards were fixed at the head of each distributary canals. As a result of this volumetric awareness, farmers as groups got motivated to save water. Later, that approach was further developed at pilot scale with the help of modern communication technologies such as SMS for updating. This approach is somewhat similar to Quick Response (QR) system recently used to address fuel shortage in Sri Lanka, the only difference being that there is no price tag. When the QR approach was used for water management, it was named as Water Quota (WQ). The motivation factor to save the allocation is the constantly updated Volumetric Awareness among the Farmer Organisations.
Outcome of WQ approach launched in 2000 under MRRP
As a result of the adoption of the WQ approach, the farmers were motivated to save water by adapting efficient on-farm irrigation water management strategies such as construction of wells to capture ground water and anicuts to capture runoff water from the farms. Locally available rain water was also used by the farmers as a strategy save their water quota. They were also motivated to adopt low water consuming export oriented high value crops by diverting from rice cultivation. For example, after the introduction of the WQ approach, the cropping intensity in System H was increased up to 165%. According to a World Bank report MRRP (2003), WQ was recognised as the best water management approach suitable for countries in South Asia. That approach was also accepted by IESL/IWMI as the best water management approach suitable for large scale irrigation culture in Sri Lanka.
Present Situation
After about 2015, attention was paid to the management of water; focus was shifted to the construction of large canals, dams and tunnels instead of agriculture. For example, as the team leader of an assignment launched in 2021 to source funding for rehabilitation of canal network under the Uda Walawe scheme, our team introduced the above approach as the first priority, as done in 2000. However, as it was the case after 2015, the focus of the implementation agencies as well as the funding sources was on repairing the hardware part of main canal.

RuGoesWild: Taking science into the wild — and into the hearts of Sri Lankans

At a time when misinformation spreads so easily—especially online—there’s a need for scientists to step in and bring accurate, evidence-based knowledge to the public. This is exactly what Dr. Ruchira Somaweera is doing with RuGoesWild, a YouTube channel that brings the world of field biology to Sri Lankan audiences in Sinhala.
“One of my biggest motivations is to inspire the next generation,” says Dr. Somaweera. “I want young Sri Lankans to not only appreciate the amazing biodiversity we have here, but also to learn about how species are studied, protected, and understood in other parts of the world. By showing what’s happening elsewhere—from research in remote caves to marine conservation projects—I hope to broaden horizons and spark curiosity.”
Unlike many travel and wildlife channels that prioritise entertainment, RuGoesWild focuses on real science. “What sets RuGoesWild apart is its focus on wildlife field research, not tourism or sensationalised adventures,” he explains. “While many travel channels showcase nature in other parts of the world, few dig into the science behind it—and almost none do so in Sinhala. That’s the niche I aim to fill.”
Excerpts of the Interview
Q: Was there a specific moment or discovery in the field that deeply impacted you?
“There have been countless unforgettable moments in my 20-year career—catching my first King cobra, discovering deep-diving sea snakes, and many more,” Dr. Somaweera reflects. “But the most special moment was publishing a scientific paper with my 10-year-old son Rehan, making him one of the youngest authors of an international peer-reviewed paper. We discovered a unique interaction between octopi and some fish called ‘nuclear-forager following’. As both a dad and a scientist, that was an incredibly meaningful achievement.”

Q: Field biology often means long hours in challenging environments. What motivates you to keep going?
“Absolutely—field biology can be physically exhausting, mentally draining, and often dangerous,” he admits. “I’ve spent weeks working in some of the most remote parts of Australia where you can only access through a helicopter, and in the humid jungles of Borneo where insects are insane. But despite all that, what keeps me going is a deep sense of wonder and purpose. Some of the most rewarding moments come when you least expect them—a rare animal sighting, a new behavioural observation, or even just watching the sun rise over a pristine habitat.”
Q: How do you balance scientific rigour with making your work engaging and understandable?
“That balance is something I’m constantly navigating,” he says. “As a scientist, I’m trained to be precise and data-driven. But if we want the public to care about science, we have to make it accessible and relatable. I focus on the ‘why’ and ‘wow’—why something matters, and what makes it fascinating. Whether it’s a snake that glides between trees, a turtle that breathes through its backside, or a sea snake that hunts with a grouper, I try to bring out the quirky, mind-blowing parts that spark curiosity.”
Q: What are the biggest misconceptions about reptiles or field biology in Sri Lanka?
“One of the biggest misconceptions is that most reptiles—especially snakes—are dangerous and aggressive,” Dr. Somaweera explains. “In reality, the vast majority of snakes are non-venomous, and even the venomous ones won’t bite unless they feel threatened. Sadly, fear and myth often lead to unnecessary killing. With RuGoesWild, one of my goals is to change these perceptions—to show that reptiles are not monsters, but marvels of evolution.”
Q: What are the most pressing conservation issues in Sri Lanka today?
“Habitat loss is huge,” he emphasizes. “Natural areas are being cleared for housing, farming, and industry, which displaces wildlife. As people and animals get pushed into the same spaces, clashes happen—especially with elephants and monkeys. Pollution, overfishing, and invasive species also contribute to biodiversity loss.”

Q: What role do local communities play in conservation, and how can scientists better collaborate with them?
“Local communities are absolutely vital,” he stresses. “They’re often the first to notice changes, and they carry traditional knowledge. Conservation only works when people feel involved and benefit from it. We need to move beyond lectures and surveys to real partnerships—sharing findings, involving locals in fieldwork, and even ensuring conservation makes economic sense to them through things like eco-tourism.”
Q: What’s missing in the way biology is taught in Sri Lanka?
“It’s still very exam-focused,” Dr. Somaweera says. “Students are taught to memorize facts rather than explore how the natural world works. We need to shift to real-world engagement. Imagine a student in Anuradhapura learning about ecosystems by observing a tank or a garden lizard, not just reading a diagram.”
Q: How important is it to communicate science in local languages?
“Hugely important,” he says. “Science in Sri Lanka often happens in English, which leaves many people out. But when I speak in Sinhala—whether in schools, villages, or online—the response is amazing. People connect, ask questions, and share their own observations. That’s why RuGoesWild is in Sinhala—it’s about making science belong to everyone.”

Q: What advice would you give to young Sri Lankans interested in field biology?
“Start now!” he urges. “You don’t need a degree to start observing nature. Volunteer, write, connect with mentors. And once you do pursue science professionally, remember that communication matters—get your work out there, build networks, and stay curious. Passion is what will carry you through the challenges.”
Q: Do you think YouTube and social media can shape public perception—or even influence policy?
“Absolutely,” he says. “These platforms give scientists a direct line to the public. When enough people care—about elephants, snakes, forests—that awareness builds momentum. Policymakers listen when the public demands change. Social media isn’t just outreach—it’s advocacy.”

Benjy’s vision materalises … into Inner Vision

Bassist Benjy Ranabahu is overjoyed as his version of having his own band (for the second time) is gradually taking shape.
When asked as to how the name Inner Vision cropped up, Benjy said that they were thinking of various names, and suggestions were made.
“Since we have a kind of a vision for music lovers, we decided to go with Inner Vision, and I guarantee that Inner Vision is going to be a band with a difference,” said Benjy.
In fact, he has already got a lineup, comprising musicians with years of experience in the music scene.
Benjy says he has now only to finalise the keyboardist, continue rehearsing, get their Inner Vision act together, and then boom into action.
“Various names have been suggested, where the keyboard section is concerned, and very soon we will pick the right guy to make our vision a reality.”
Inner Vision will line-up as follows…
Anton Fernando

Benjy Ranabahu:
Ready to give music
lovers a new vision
(Lead guitar/vocals): Having performed with several bands in the past, including The Gypsies, he has many years of experience and has also done the needful in Japan, Singapore, Dubai, the Maldives, Zambia, Korea, New Zealand, and the Middle East.

Can Sri Lanka’s premature deindustrialisation be reversed?

As politicians and economists continue to proclaim that the Sri Lankan economy has achieved ‘stability’ since the 2022 economic crisis, the country’s manufacturing sector seems to have not got the memo.
A few salient points need to be made in this context.
First, Sri Lankan manufacturing output has been experiencing a secular stagnation that predates external shocks, such as the pandemic and the Easter Attacks. According to national accounts data from UNIDO, manufacturing output in dollar terms has basically flatlined since 2012. Without a manufacturing engine at its core, it is no surprise that Sri Lanka has seen some of the lowest rates of economic growth during this period. (See graph)
Second, factory capacity utilisation still remains below pre-pandemic levels. Total capacity utilisation stood at 62% in 2024, compared to 81% in 2019. For wearing apparel, the country’s main manufactured export, capacity utilisation was at a meagre 58% in 2024, compared to 83% in 2019. Given the uncertainty Trump’s tariffs have cast on global trade, combined with the diminished consumer sentiment across the Global North, it is hard to imagine capacity utilisation recovering to pre-pandemic levels in the near future.
Third, new investment in manufacturing has been muted. From 2019 to 2024, only 26% of realised foreign investments in Board of Investment enterprises were in manufacturing. This indicates that foreign capital does not view the country as a desirable location for manufacturing investment. It also reflects a global trend – according to UNCTAD, 81% of new foreign investment projects, between 2020 and 2023, were in services.
Taken together, these features paint an alarming picture of the state of Sri Lankan manufacturing and prospects for longer-term growth.
What makes manufacturing so special?
A critical reader may ask at this point, “So what? Why is manufacturing so special?”
Political economists have long analysed the transformative nature of manufacturing and its unique ability to drive economic growth, generate technical innovation, and provide positive spillovers to other sectors. In the 1960s, Keynesian economist Nicholas Kaldor posited his famous three ‘growth laws, which argued for the ‘special place’ of manufacturing in economic development. More recently, research by UNIDO has found that 64% of growth episodes in the last 50 years were fuelled by the rapid development of the manufacturing sector.
Manufacturing profits provide the basis on which modern services thrive. London and New York could not have emerged as financial centres without the profits generated by industrial firms in Manchester and Detroit, respectively. Complex and high-end services, ranging from banking and insurance to legal advisory to logistics and transport, rely on institutional clients in industrial sectors. Meanwhile, consumer-facing services, such as retail and hospitality, depend on the middle-class wage base that an industrial economy provides.
Similarly, technologies generated in the manufacturing process can have massive impacts on raising the productivity of other sectors, such as agriculture and services. Indeed, in most OECD countries, manufacturing-oriented private firms are the biggest contributors to R&D spending – in the United States, 57% of business enterprise R&D spending is done by manufacturing firms; in China it is 80%.
It has become increasingly clear to both scholars and policymakers that national possession of industrial capacity is needed to retain advantages in higher value-added capabilities, such as design. This is because some of the most critical aspects of innovation are the ‘process innovations’ that are endemic to the production process itself. R&D cannot always be done in the comfort of an isolated lab, and even when it can, there are positive spillovers to having geographic proximity between scientists, skilled workers, and industrialists.
Produce or perish?
Sri Lanka exhibits the telltale signs of ‘premature deindustrialisation’. The term refers to the trend of underdeveloped countries experiencing a decline in manufacturing at levels of income much lower than what was experienced by countries that managed to break into high-income status.
Premature deindustrialisation afflicts a range of middle-income countries, including India, Brazil, and South Africa. It is generally associated with the inability of domestic manufacturing firms to diversify their activities, climb up the value chain, and compete internationally. Major bottlenecks include the lack of patient capital and skilled personnel to technologically upgrade and the difficulties of overcoming the market power of incumbents.
Reversing the trend of premature deindustrialisation requires selective industrial policy. This means direct intervention in the national division of labour in order to divert resources towards strategic sectors with positive spillovers. Good industrial policy requires a carrot-and-stick approach. Strategic manufacturing sectors must be made profitable, but incentives need to be conditional and based on strict performance criteria. Industrial can choose winners, but it has to be willing to let go of losers.
During the era of neoliberal globalisation, the importance of manufacturing was underplayed (or perhaps deliberately hidden). To some extent, knowledge of its importance was lost to policymakers. Karl Marx may have predicted this when, in Volume 2 of Das Kapital, he wrote that “All nations with a capitalist mode of production are, therefore, seized periodically by a feverish attempt to make money without the intervention of the process of production.”
Since the long depression brought about by the 2008 financial crisis, emphasis on manufacturing is making a comeback. This is most evident in the US ruling class’s panic over China’s rapid industrialisation, which has shifted the centre of gravity of the world economy towards Asia and threatened unipolar dominance by the US. In the Sri Lankan context, however, emphasis on manufacturing remains muted, especially among establishment academics and policy advisors who remain fixated on services.
Interestingly, between the Gotabaya Rajapaksa-led SLPP and the Anura Kumara Dissanayake-led NPP, there is continuity in terms of the emphasis on the slogan of a ‘production economy’ (nishpadana arthiakaya in Sinhala). Perhaps more populist than strictly academic, the continued resonance of the slogan reflects a deep-seated societal anxiety about Sri Lanka’s ability to survive as a sovereign entity in a world characterised by rapid technological change and the centralisation of capital.
Nationalist writer Kumaratunga Munidasa once said that “a country that does not innovate will not rise”. Amid the economic crises of the 1970s, former Prime Minister Sirimavo Bandaranaike popularised a pithier exhortation: “produce or perish”. Aside from their economic benefits, manufacturing capabilities are the pride of a nation, as they demonstrate skill and scientific knowledge, a command over nature, and the ability to mobilise and coordinate people towards the construction of modern wonders. In short, it is hard to speak of real sovereignty without modern industry.
