I am interested in interdisciplinary research on issues related to natural resource management. Much of my previous as well as current work focuses on resource use and its links to conservation and local livelihoods in the aquatic ecosystems of Western Ghats Biodiversity Hotspot in South India. With my broad academic and research background in fisheries science/aquaculture (Mahatma Gandhi University-India; University of Madras-India; Institute of Hydrobiology of the Chinese Academy of Sciences- P. R. China) and conservation biology (Durrell Institute of Conservation & Ecology, University of Kent –UK), I am also interested in addressing research questions related to small scale fisheries governance and sustainable aquaculture.
Freshwater fish are intricately linked to the livelihoods of local communities in the Western Ghats Hotspot providing a range of benefits including a source of food for the local population and income for the fishers and market traders in the region. Freshwater fisheries in this region are however under increasing pressure due to dwindling populations of important harvested species coupled with poor governance and institutional support. The growing concerns over actual and/or potential depletion of many species, and the social and economic hardships that will befall upon people in such resource-dependent communities makes conservation and management of small scale artisanal fisheries an urgent priority. However, the data-sparse nature of such fisheries has meant that their management is an ultimate challenge.
I use a combination of biological, socio-economic, ethno-ecological and management methods, to improve the understanding of freshwater fish species, corresponding small scale fisheries and their role in the livelihood portfolio of local communities in the Western Ghats, with an aim to develop policy recommendations for conservation and management.
Donors and Collaborators
My research in the Western Ghats has been funded by international agencies and organizations like Critical Ecosystem Partnership Fund (CEPF), North of England Zoological Society/Chester Zoo (UK), Rufford Foundation (UK), Endangered Species International (USA), National Science Foundation (USA) and the Columbus Zoo (USA). In addition, I am also involved in projects funded by the Chelonian Research Foundation (USA) and the Oriental Bird Club (UK) as a co-investigator. I also collaborate with a number of national and international organizations, research institutes and universities including the Ashoka Trust for Research in Ecology and Environment (ATREE, India), IUCN-Freshwater Biodiversity Program (Cambridge, UK), New England Aquarium (Boston, USA), Durrell Institute of Conservation and Ecology (Kent, UK), Institute of Sufficiency Economy Research and Promotion at Chiang Mai University (Thailand) and the Department of Zoology at the University of Kerala (India) in research and policy issues relevant to biodiversity conservation and sustainable use.
