• Impacts of Climate Variability and Change on Tea Plantations in Sri Lanka (2018 - 2019)
• Modeling the Impacts of a Variable and Changing Climate on Rice and Sugarcane Agricultural Systems in Sri Lanka. (2012 - 2016)
• South Asia Strategy Development for CCAFS and Toolkit for crop yield (2012 – 2015).
• ENSO Impacts on Cereals in Sri Lanka (2009 – 2010)
• Climate Change and Variability and Tea and Coconut (2002 – 2005)
• Climate Variability and Rice Production in Sri Lanka (1998 – 2002) 

This was a collaborative initiative between the Federation for Environment, Climate and Technology and University of Peradeniya which aimed to assess the impacts of climate on the Tea Plantation System in Sri Lanka, with the focus on the impacts on tea production, yield. This was a one-year project sponsored by the Dilmah Conservation Sustainable Agriculture Research Centre – DCSARC, Sri Lanka.  The objectives of the project were to outline the needs assessment and knowledge resource including metadata, Climate Analysis on tea data, identification of climate data for tea sector needs, climate Diagnostics, and analysis of Climate Impacts on Tea.

The Agricultural Model Intercomparison and Improvement Project (AgMIP) was a major international effort linking the climate, crop, and economic modeling communities with cutting-edge information technology to produce improved crop and economic models and the next generation of climate impact projections for the agricultural sector. The project was sponsored by the UK Department for International Development (DFiD).   This work was led by Columbia Climate Center,  NASA-GISS, Oregon University and the University of Florida. The objective of the project was to substantially improve the characterization of world food security due to climate change and to enhance adaptation capacity in both developing and developed countries. The project was done in collaboration with Department of Agriculture, University of Peradeniya, University of Ruhuna, Rajarata University and Sugarcane Research Institute. Through this project climate change assessments were conducted, impact assessments for rice and sugarcane were undertaken and agricultural systems analyze the climate-crop-system economics.  

This project is a component of the South Asia program of the Climate Change, Agriculture and Food Security (CCAFS) programe where initially scoping of the use of climate information for agricultural practices were undertaken with IRI Therefore at the invitation of the Natural Resources Management Centre (NRMC) of the Department of Agriculture, we supported their work on evaluating a toolkit developed by the South Asia project for crop simulation   and  this for Sri Lanka. The toolkit integrated spatial data of weather, soil, crop management practices, crop distribution and crop parameters to provide qualitative and quantitative crop status spatially. The Sri Lanka team was led by the Director of the Natural Resources Management Centre of the Department of Agriculture and the collaborators included staff from the Rice Research Development and Training Institute, and the University of Peradeniya, The Foundation for Environment, Climate and Technology (FECT) played a supporting role by providing the weekly hydro meteorological advisories to the Mahaweli Authority (MASL). This was sponsored by CCAFS and FECT contributed probono.

After our earlier work had shown the significant climate impacts on rice agriculture, under this project we went into details on the role of production, area and yield by district. e assessed the relationship of Sri Lankan rice production; area harvested and yields with rainfall and El Nino – Southern Oscillation (ENSO) to characterize the climate impact better and to help develop seasonal predictions. This project was collaboratively funded by FAO and Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA) through the University of Philippines. The project was conducted as a case study in 11 countries including Bangladesh, Cambodia, China, India, Indonesia, Malaysia, Pakistan, Philippines, Sri Lanka, Thailand, and Vietnam simultaneously.

The project was a global prototype on the use of climate information for Climate Impact Assessment, to generate Adaptation options for Tea and Coconut under the Adaptation and Impact Assessment to Climate Change (AIACC) program. . This project was a three-year collaborative undertaking between five Sri Lankan organizations: the Department of Meteorology (DoM), Tea Research Institute (TRI), Coconut Research Institute (CRI) and University of Peradeniya and IRI. It was funded by the global change system for Training, Analysis and Research (START). We engaged in climatic analysis, impact assessment, development of adaptation strategies and capacity building. We have developed climate change assessments and contributed to an operational prediction scheme for coconut production.

Our work was to show that climate information is useful for understanding rice agriculture and has policy implications.  Our research has indicated a significant relationship between rice production in Sri Lanka and ENSO. These findings are useful to construct the use of seasonal climate predictions for agricultural management and policy-making. We collaborated with colleagues at the Institute of Fundamental Studies(IFS), International Research Institute for Climate Prediction (IRI),  and Department of Agriculture. The work was supported by IFS and IRI.
