Drought events have critical impacts on agricultural production yet there is little consensus on how these should be measured and defined. This has implications for drought research and policy, which tends to either define droughts purely based on rainfall or focus uniquely on 'hot' droughts when temperature is considered.

Exploit a unique panel of 75 metro areas (‘cities’) across the globe and employ a city-fixed effects model to identify the determinants of within-city changes in air pollution concentration between 2005 and 2011.

Decentralization reforms in Indonesia have led to local communities negotiating logging agreements with timber companies for relatively low financial payoffs and at high environmental cost. This paper analyzes the potential of payments for environmental services (PES) to provide an alternative to logging for these communities and to induce forest conservation.

This paper investigates the direct and indirect impacts of ethanol production on land use, deforestation and food production. A partial equilibrium model of a national economy with two sectors and two regions, one of which includes a residual forest, is developed.
