Research and Conservation Interests:
Insect taxonomy, ecology and conservation
- revitalising insect taxonomy by rightly marrying conventional taxonomy to the modern techniques and linking these efforts to conservation and sustainable management of natural resources.
-understanding the impacts of various ecosystem processes on insect diversity, in order to define conservation plans to the benefits of insect diversity.
- ‘Conservation bio-control’: An ecological and practical approach to the management of crop arthropod pests by careful landscaping and scientific manipulation of uncultivated vegetation in agro-ecosystems.
-review the conservation policies and liason with the policy makers to bring scientific rigor to make the policies robust.
Deliberative democratic approaches in conservation
The experiences have taught us that our conventional conservation paradigms are largely top down and ill suited to the current day conservation needs. Even the much celebrated participatory / joint conservation efforts are not different.
I try to address some of the conservation issues faced by Vembanad Lake (Kerala)- the largest tropical wetland ecosystem on the southwest coast of India and a designated Ramsar site , through a deliberative democratic process. In the process of deliberative democratic conservation the conservation, policies and priortisation are done through consensus evolved through deliberations among various stakeholders and transfer of responsibility over its harvest and management to them.
