Issues in Ecology, Issue 09: Water in a Changing World
This report illustrates the disruption of the global water cycle as a result of human activities. The global hydrological cycle’s surface and ground water processes are detailed. The global distribution of freshwater resources and its accessibility to human populations is discussed. The increasing human demand for fresh water sources is addressed, while explaining the differences betwee...

Use of Acacia by Maasai nomadic herders of southern Kenya during drought, and its ecosystem-level consequences.
This collection of twelve photographs illustrates how the Maasai use Acacia during prolonged drought, and the impacts of that use on long-term ecosystem processes. The Maasai are the largest group of nomadic livestock herders in eastern Africa. They greatly contribute to Kenya's beef industry, and cattle are their most important livestock. The Masai live in savanna ecosystems having well-defined...

Where Does Water Go When it Rains?
This short film includes interviews with water researchers and presents basic concepts of hydrologic cycle. Understanding where water goes is important for understanding the environmental effects of many of our activities, from land development to fertilizer use or how will harvesting trees change the likelihood of flooding or landslides.

Extreme droughts in the southeast- How do we sustain ecosystem services?
Predicted increased variability in rainfall together with the effects of fast-growing population centers, hydropower development, and irrigated agriculture will likely continue to alter landscape and biotic diversity of freshwater ecosystems in the Apalachicola-Chattahoochee-Flint (ACF) River Basin in Alabama, Georgia and Florida. Adaptations to these climatic changes among water users provide...
