Nagavarapu has interdisciplinary projects that examine environmental outcomes in Mexico and Brazil. In Brazil, he looks at the relationship between changes in agricultural prices, wages and forest cover with particular focus on the issue of uses of sugar cane for ethanol. In Mexico, he works with marine biologists Heather Leslie and Sheila Walsh to look at the management of fisheries resources. In particular, the team is examining the extent to which cooperatives can more effectively manage fishing resources through establishment of rights over certain fishing grounds.
