His active research program lies at the intersection between wider economic and political processes and the equity and sustainability outcomes of decentralised nature resource management at the local level. His current projects are in Nepal and Australia. Recently completed research projects are – a) the environmental planning stalemate concerning the Malabar Headland Sydney; b) collaborative planning in Queensland, and c) the politics of equity and sustainability in decentralised natural resource management in NSW. He has also completed projects in equity and sustainability in Nepalese community forestry. He uses a ‘critical realist’ and ‘pragmatic approach’ to environment and development problems in which rigorous explanation is generally balanced with the provision of policy alternatives. Krishna focuses on grounded analysis of socio-ecological dynamics through a multi-scale perspective where the role of unequal power relations in constituting a politicised environment is a central theme. His research projects give particular attention to the ways in which problems of natural resource management are linked to systems of social hierarchy and political and economic control which affect poor and minority groups. Most of his work has been based on empirical social science research or action-research, particularly in South Asia (Nepal and India) and Australia.
