Wildlife economics: A study of direct use values in Botswana's wildlife sector

摘要: The wildlife resources in Botswana were studied to determine their direct use values. Cost- benefit analysis was applied develop models for viewing, safari hunting, community-based use, game ranching, ostrich farming, crocodile farming and elephant utilisation product processing. Various planning policy options analysed within the sector. Contingent valuation used estimate economic characteristics of demand wildlife-viewing tourism. A linear programniing model, which optimises contribution activities national income, a framework constraints, developed whole findings confirm that can contribute positively sustainably this happen without loss biological diversity. Wildlife's potential will not likely exceed four percent gross domestic product. flow positive values from sector justifies anticipated public expenditures it. In expansion emphasis should be placed on and, lesser extent, production, community high value areas. Later, as capital, labour management become more abundant, diversified all uses fully. ban consumptive would result 16 less added sector, involve 75 land. Even with some 88 estate cannot generate any medium term. survival depends largely its ability value. This through an array yielding values, land zoning precludes indirect non-use also captured where possible.
