South Asian Nitrogen Hub (SANH) Research Study at Dilmah’s Queensberry Estate
Working to Understand the Impact of Nitrogen Pollution from Ammonia on South Asian Forest Ecosystems
Since 2020, the UKRI GCRF South Asian Nitrogen Hub (SANH), in collaboration with Dilmah Tea, Dilmah Conservation, and the University of Peradeniya, has been conducting a study on the impact of ammonia pollution within a tropical forest ecosystem.
A news release on the subject from Dilmah explained emissions of ammonia to air represent a form of nitrogen waste, which is mainly lost from fertilizers and manures, reducing productive output in agriculture.
The project partners established an experimental site within the Rilagala Forest Sanctuary, adjacent to the Dilmah Queensberry Estate. Notably, South Asia has become a hot spot for nitrogen waste, leading Sri Lanka to lead international ambition to halve nitrogen waste by 2030, as declared during the Colombo Declaration of UN Day in 2019. The experimental site has now become a permanent monitoring plot.
Nitrogen, essential for food and protein production, poses a significant threat due to the excessive nitrogen waste generated from fossil fuel burning and the overuse of fertilizers. One key form of nitrogen release into the environment is ammonia, which can have adverse impacts on natural ecosystems and formation of fine particulate matter air pollution, which is damaging for human health.
The SANH research project addresses the pressing need for baseline data on the consequences of nitrogen pollution in much understudied South Asian Forest ecosystems, aiming to provide crucial insights for sustainable nitrogen management policies.
An integral part of this research involves the innovative use of a controlled ammonia enhancement system in forests, making it one of only two such sites globally. In this system the atmospheric ammonia pollution equivalent to a small farm is simulated. A system was developed to release ammonia only under specific wind conditions, ensuring it reaches designated areas where lichen and vegetation research plots are located.
The UKRI GCRF South Asian Nitrogen Hub (SANH) collaborates with 32 leading research organizations across South Asia and the UK. In Sri Lanka, the research team is led by Professor S.P. Nissanka of the University of Peradeniya, in partnership with the Hub lead Prof. Mark Sutton, of the UK Centre for Ecology & Hydrology, Edinburgh. Specific expertise is provided by Dr. Gothamie Weerakoon, an internationally renowned lichen expert based at the Natural History Museum, London who previously collaborated with Dilmah Tea on a book about lichens and Dr. Ajinkya Deshpande, an environmental ecologist at UKCEH.
Professor Nissanka commented: “This is a superb opportunity for Sri Lanka to demonstrate its international leadership in both nitrogen science and policy. The Rilagala experiment on ammonia is the first of its kind in the whole of Asia”.
Professor Sutton added, “We are looking at work to raise awareness by better understanding the key threats. For example, seeing how nitrogen pollution is damaging coral reefs, exacerbating the problem of climate change with coral bleaching, seeing how nitrogen is affecting forest biodiversity, which is little studied, and finally we are looking at bringing those fluxes and flows together.”
Dr. Deshpande, emphasized “This experiment serves as a platform on which other institutes can build, using it as an example of the critical importance of data collection. Our methodology can be replicated elsewhere, broadening the impact of our work.”
In 2020, a research site was established at 1600 meters within the Rilagala Forest Reserve, which had been surrounded by Queensberry Estate tea plantations for nearly two centuries. This site offered ideal conditions and a rich biodiversity of lichen species, serving as effective bioindicators for monitoring nitrogen pollution.
Dr. Gothamie Weerakoon, said “The conclusions drawn from this data are crucial for sustainable farming, crop development, and improved livelihoods. If other corporate sector organizations who support such research, like Dilmah, come forward, it will illuminate the future of Sri Lanka and South Asia.”
Dilmah’s Climate Change Research Centre at Queensberry Estate in Nawalapitiya, the only privately owned climate change center in Sri Lanka, has provided unwavering logistics support to the SANH team, even during the COVID-19 pandemic and economic crises, demonstrating their dedication to climate change research. Local student researchers working on the project are supported by Dilmah through the Climate Research Centre, offering them valuable exposure to international collaborators, and raising awareness about the impact of climate change.

Sri Lanka’s 2026 economic growth predicted to be around 4-5 percent
Sri Lanka’s economic growth for 2026 will be around 4-5 percent, Central Bank Governor Dr. Nandalal Weerasinghe said.
The Governor indicated the estimated economic growth while announcing the Central Bank’s policy agenda for this year, last Thursday.
‘The Central Bank’s 2026 growth estimation is higher than the growth prediction of the IMF and the World Bank and is achievable, the Governor told the media while announcing the Central Bank’s policy agenda for 2026.
Dr. Weerasinghe added: ‘The Central Bank will introduce a benchmark intra-day reference exchange rate this year to ensure transparency in the foreign exchange market.
‘The absence of a reference exchange rate has held back the expansion of the Sri Lankan forex market and discouraged the trading of rupee-denominated derivatives Governor said.
‘The Central Bank last year carried out the necessary preliminary work to implement the benchmark spot exchange rate.
‘The benchmark intra-day reference exchange rate will be introduced in 2026 to foster a transparent foreign exchange market.
‘This benchmark will guide market participants, help reduce volatility and promote more competitive pricing on a given date, thereby enabling the introduction of more innovative products in the foreign exchange market.
‘Sri Lanka’s foreign exchange market has limited derivatives like currency swaps and options aiming to deepen markets and attract inflows.
‘However, these instruments failed after a lack of reliable reference exchange rate amid concerns over excessive speculation, rupee over-appreciation risks and interventions distorting clean floating rates.’
Meanwhile, currency dealers welcomed the move and said it will help to deepen the market.
“This will expand the market with more products and promote rupee-denominated derivatives, a currency dealer from a local bank said.
“It is something the market wanted to fix in derivative prices. This is a pricing mechanism for the rupee, he added.

Sevalanka Foundation and The Coca-Cola Foundation support flood-affected communities in Biyagama, Sri Lanka
With funding support from The Coca-Cola Foundation (TCCF), the Sevalanka Foundation has launched a humanitarian relief programme to support flood-affected communities in Biyagama. The initiative focuses on restoring access to safe water, healthcare services, and essential public facilities during the critical recovery period following the Cyclone Ditwah.
Working closely with the Divisional Secretariat, the program prioritizes the cleaning and rehabilitation of contaminated dug and tube wells, helping address the urgent post-flood challenge of access to safe water. This intervention will also support the cleaning and reopening of essential public spaces, including schools, and Grama Niladhari (GN) offices, enabling authorities and communities to resume daily activities safely. The Sevalanka Foundation and TCCF, as part of the initial response, have also donated water pumps to the Divisional Secretariat to support immediate water extraction and clean-up efforts.
In addition, as the second main component of the project, and based on the guidance of the Medical Officer of Health (MOH), support is being provided to MOH-operated healthcare facilities to restore access to emergency and essential medical services. This support includes sanitization, debris removal, hazard stabilization, and the provision of emergency medical supplies such essential medicines and hygiene products. Medical camps staffed by doctors and senior nurses will be conducted through MOH offices to provide prioritized groups of persons with health, nutrition and hygiene related relief items.
