"A tradable development rights (TDR) program focusing on biodiversity conservation faces a crucial problem defining which areas of habitat should be considered equivalent. Restricting the trading domain to a narrow area could boost the range of biodiversity conserved but could increase the...

"This paper relaxes some key assumptions in the probabilistic approach to fiscal sustainability. First, the authors identify structural breaks over the sample period used to estimate the covariance matrix of the shocks to the debt ratios. Second, the assumption of normality of the shocks is...

"Conservation of high-biodiversity tropical forests is sometimes justified on the basis of assumed hydrological benefits - in particular, the reduction of flooding hazards for downstream floodplain populations. However, the "far-field" link between deforestation and distant flooding has been...

This issue of environment matters celebrates the 2010 international year of biodiversity and describes some of the challenges and opportunities in protecting biodiversity for the benefit of humankind. From the world's highest mountain ranges to the lowland plains, and from the great oceans and...

The World Bank's mission is to alleviate poverty and support sustainable development. Climate change is a serious environmental challenge that could undermine these goals. Since the industrial revolution, the mean surface temperature of earth has increased an average 2 degree Celsius due to the...

Climate change is a serious environmental challenge that could undermine the drive for sustainable development. Since the industrial revolution, the mean surface temperature of earth has increased an average of 1degree celsius per century due to the accumulation of greenhouse gases in the...
