简介:坦噶尼喀湖(LakeTanganyika)位于非洲东部大裂谷地区,是世界第二深水湖。坦湖流域涉及坦桑尼亚、布隆迪、赞比亚和刚果(金)4个主权国家,是典型的跨界流域,对流域进行有效管理必需经沿岸四国共同协调开展,尤其在流域资源利用和环境保护方面。坦噶尼喀湖目前水环境质量良好,但受气候变化、外来生物入侵、水土流失加剧以及沿岸城市人口增长过快、城市建设无序发展带来的点源和面源污染等自然和社会经济因素的多重影响。沿岸四国由于历史原因,在渔业资源分配和环境管理标准等方面存在较多矛盾和不统一,2008年成立的坦噶尼喀湖流域管理局受四国政府和UNEP等国际组织的支持作为该湖国际性事务的管理机构,主要发挥协调作用推动坦湖流域各国资源利用与环境管理的一体化。在梳理和分析坦噶尼喀湖流域水资源状况及渔业资源状况的基础上,提出该流域当前资源开发利用与利益冲突的问题,阐述了流域管理合作的发展以及流域管理机构的主要特点和结构,并讨论总结了有关经验和结论。
