Profile

My research focus is on land and water resources development & management leading to sustainable ecosystems, agriculture, and water and food security. The continuous increasing global population will put more pressure on land and water as they are the most important natural resources, as far as water supply, agriculture and ecosystem sustainability are concerned. The greatest challenge that scientists, engineers, economists and policy makers face today is guaranteeing water and food security for the ever increasing global population while managing land and water resources without damaging the vital eco-systems. Development and management of water resources has become a very complex issue since water is considered a social good. Changing climate has put additional pressures and complexities on land and water resources. Maintaining economic efficiency, social equity and ecosystem sustainability while achieving water and food security for people therefore, has been received much attention today than ever before. Thus, interdisciplinary/transdisciplinary approaches are needed to develop and manage land and water resources. On-going research works: (i) Mapping spatio-temporal variability of soil hydraulic and physical properties using EMI in managed and natural landscapes in Western Newfoundland; (ii) Hydrogeophysical characterization of agricultural soils with integrated GPRI-EMI; (iii) Quantitative and qualitative inventory of organic waste in support of enhanced valorization through integrated re-use; (iv) Water retention properties of agricultural soils in western Newfoundland amended with Biochar; (v) High value added agricultural production through on-farm, integrated, re-use of nutrients from dairy liquid waste streams; (vi) Long term climatic data analysis and trend prediction: upcoming challenges for agricultural management in western Newfoundland;  (vii) Interdisciplinary water resources management (IWRM) in the context of climate change, gender and equity issues in Sri Lanka.
