Transboundary Environmental Impact Assessment as instrument to abate conflict among basin countries of international rivers

国际河流或湖泊流域的流域国家同意以《埃斯波公约》为基础的跨界环境影响评估框架的先决条件如下：水体污染影响所有流域国家，如里海的情况。两个国家共享河流流域，一个国家位于其中一些河流的上游，而另一个国家位于其他河流的上游，例如加拿大和美国共享的河流。随着区域经济一体化进程的推进，流域国家在各个领域相互依存，湄公河流域就是一个例子。

Following prerequisites were identified for basin countries of international river or lake basins to agree to a framework of transboundary environmental impact assessment based on the Espoo Convention : Pollution of water body affects all the basin countries as in the case with Caspian Sea. Two countries share river basins, and one country is situated in upstream for some of them, while the other country is in upstream for the rest, e. g. rivers shared by Canada and the United States. Basin countries are mutually dependant on various sectors thanks to progress of regional economic integration, like in the Mekong River basin.
