The households who live in the rural areas of Northern Ghana base their subsistence on natural resources, which are threatened by the progressive desertification and increased frequency of extreme weather events in the region. We draw on a field work and on extensive secondary data sources to...

We develop a new methodology to estimate the elasticity of urban costs with respect to city population using French land price data. Our preferred estimate, which handles a number of estimation concerns, stands at 0.041. Our approach also yields a number of intermediate outputs of independent...

The ICMS-Ecológico is a fiscal transfer mechanism from states to municipalities, implemented in the early 1990's in Brazil, to reward municipalities for the creation and management of protected areas. This paper investigates the efficiency of this mechanism by testing for the presence of...

We build a benchmark framework to study optimal land use, encompassing land use activities and environmental degradation. We focus on the spatial externalities of land use as drivers of spatial patterns : even if land is immobile by nature, location's actions affect the whole space through...

The expansion of crop and pastures to the detriment of forests results into an increase in atmospheric CO2. A first obvious cause is the loss of forest biomass and soil carbon during and after conversion. A second, generally ignored cause, is the reduction of the residence time of carbon when...
