I am a Lead Environmental Economist in the World Bank, where among a host of other things, I coordinate the climate change work agenda in the South Asia Region. Prior to this I was Professor in the School of Economics at the University of Adelaide in Australia. My publications and research interests have spanned many areas of economics including development economics, game theory, environmental economics and macroeconomics. In the past I have advised numerous international agencies such as the OECD, FAO, UNESCO and governments. The environment and conservation of endangered species are matters of long standing interest and concern to me. I have published numerous papers on the economics of endangered species conservation – an issue where solutions remain highly elusive and ever more challenging.
