Freshwater, land, and biologic interactions: Changes and impacts



Water is essential to human life and the functioning of all terrestrial ecosystems. As human population expands and anthropogenic effects induce climate change, many water availability systems are modified and stressed. This stress will be felt differently in various regions, depending on the complex relationships of water, vegetation, land, and human activity. Yet many aspects of the interactive biogeochemical cycles are poorly understood, making it difficult to predict the effect of changes in climate or land use on water as an integral element affecting ecosystem processes and sustainability.
