Still Department of Geography and Institute for Computational Earth System Science, University of California, Santa Barbara, USA Abstract Sugar cane cropping for biofuel production reduces water discharge from a northern Indian basin and threatens downstream communities. Regulators want to partition blame between climate change–induced declines in mountain snowpack and excessive evaporation from poorly managed fields. In the same basin, a tiger is found shot. Is it the nuisance animal that has been tormenting local communities, or is it a different animal poached from the upland forests? Insight into these issues may lie in a new approach to analyzing and interpreting isotopic data. Published 31 March 2009.
