CLIMATE CHANGE AND AGRICULTURAL WATERSHEDS
Many scientists predict that the Earth's mean temperature will rise
several degrees, enough to affect the hydrologic regime of entire
regions. A newly released book, "Climate Change and the Global
Harvest: Potential Impacts of the Greenhouse Effect on Agriculture,"
written by Cynthia Rosenzweig and Daniel Hillel, explores these
potential impacts. The authors believe that many of the roles played
by natural ecosystems such as oxygen-carbon dioxide exchange, control
of runoff, evaporation, groundwater recharge and nutrient recycling are
in jeopardy due to climate change. Agriculture may be changed rapidly
and even disappear in some areas due to rising sea levels and saltwater
intrusion. The book explores several aspects of climate change,
including the role of soil resources, water resources, and food
security.
