东非维多利亚湖环境问题对策:原因和政策方案分析
Mitigation of Environmental Problems in Lake Victoria,East Africa:Causal Chain and Policy Options Analyses
摘要
维多利亚湖是一个国际性水域,为沿岸社区提供着很多极其重要的环境服务,在过去30多年的时间里,该湖泊受到周边人类各项相互关联的活动越来越显著的压力,例如过度捕捞、外来物种入侵、工业污染、富营养化和泥沙淤积等。本文分析了维多利亚湖过度捕捞和污染问题产生的根源,并提出了政策性建议,这些建议有助于修复和减轻该湖的环境退化问题。
Lake Victoria is an international waterbody that offers the riparian communities a large number of extremely important environmental services.Over the past three decades or so,the lake has come under increasing and considerable pressure from a variety of interlinked human activities such as overfishing,species introductions, industrial pollution,eutrophication,and sedimentation.In this paper we examine the root causes for overfishing and pollution in Lake Victoria and give possible policy options that can help remediate or mitigate the environmental degradation.
