Rubber Research Institute of Sri Lanka

Ministry of Plantation Industries



Adaptive Research Unit

This unit uses both ”Top-down” and “Bottom-up” approaches to refine the technologies available in the large-scale plantation sector in favour of smallholders and plan the future research to cater the smallholder requirements, respectively.  Among the research activities of the unit, developing rubber based farming systems particularly to the non-traditional areas whilst characterizing the socio economic conditions of smallholdings is in top priority.

Obtained the basic degree in BSc Agriculture from the University of Peradeniya and joined RRISL as a Research Officer in 2005. Has completed the PhD on Environmental Economics at the University of Sri Jayewardenepura in 2009 and working as a Principal Research Officer in the Adaptive Research Unit. Currently engage in adaptive research activities and carbon market. Contributed to the rubber industry by developing models for assessment of timber, biomass and carbon in rubber plantations, identifying socio-economic factors affecting the profitability of rubber based intercropping systems, assessing financial and economic viability of rubber cultivation under different cultivation scenarios, shortening the lifespan of rubber for high returns, establishing rubber in Eastern and Northern regions of the country by developing agronomic protocols, characterizing the livelihood and environmental impacts. Have published over 50 scientific publications and was honored by National Awards for Excellence in Agricultural Research in Sri Lanka 2014, National Research Council Merit Award for Scientific Publication in 2014 and Presidential Research Award in 2004.

Current research interests - Rubber cultivation to non-traditional areas; Socioeconomics of rubber cultivation; Carbon trading
