Until well into recent times, a high level of connectivity existed among ecosystems. Through the ever-increasing extent and intensity of human exploitation of natural resources, however, the pattern of human activities as islands in a sea of nature has become reversed in most of the worlds regions. Habitat fragmentation is now one of the most important causes of the decline in biodiversity.
This book tells the story of times past, when wetlands were considered as wastelands and decision makers and managers were unaware of their benefits, a time when the adverse impacts of hydropower and irrigation schemes on ecosystems and people downstream seemed unimportant. Today wetland ecosystems are viewed as essential elements in integrated river basin planning, which draws upon the most appropriate modern science and traditional knowledge.
