Economics and the conservation of global biological diversity

摘要: This paper explores the relationship between economics and biodiversity conservation with minimal recourse to jargon, making issue accessible even non-economist. It deals concepts of cost benefit as they apply biodiversity. Since is an area where no clear measure benefits exists, process project selection for a financial mechanism such Global Environment Facility (GEF) becomes especially complex. The reviews measures biodiversity, assesses what currently known about extinction rates species loss, looks at efforts place value on also investigates question why being eroded, argues that main economic causes erosion are pressures exerted by population growth convert available land, under-investment in recommends policies reduce returns land conversion eliminating subsidies other policy distortions; aim increase conservation, example, conferring enforcing property rights those who sustainably manage resources, instituting mechanisms capture global sustainable use. Finally, considers ways which GEF might alleviate problem
