Human-kind and ecological systems are currently facing one of the toughest challenges: how to feed more billions of people in the future within the perspective of climate change, energy shortages, economic crises and growing competition for the use of renewable and non renewable resources. This challenge is even more crucial given that we have not yet come close to achieving the Millennium Development Goal of halving the number of people living in extreme poverty and hunger. Scientists and relevant stakeholders are now voicing a clear message: that multiple challenges the world is facing require innovative, multifaceted, science-based, technological, economic and political approaches in theoretical thinking, decision making and action. With this background central to survival and well-being, the purpose of this volume is to formulate and promote relevant theoretical analysis and policy recommendations. The major perspective of this publication is that paradigm and policy shifts at all levels are needed urgently. This is based on the evidence that agriculture in the 21st century will be undergoing significant demands, arising largely from the need to increase the global food enterprise, while adjusting and contributing to climate change adaptation and mitigation. Global Food Insecurity aims at providing structure to effect achievement of this critically needed roadmap.

In 1984, the Conference on Environmental Quality, the Environmental Protection Agency, and the National Science Foundation, convend a series of panel meetings to discuss long-term environmental issues. "Environmental Monitoring, Assessment, and Management" is the result of that prestigious conference. Drawing on contributions from nationally recognized scientists and experts from industry and government, this collection of papers will help to redirect long-term environmental research and development.

In 1984, the Conference on Environmental Quality, the Environmental Protection Agency, and the National Science Foundation convened a series of panel meetings to discuss long-term environmental issues. "Preserving Ecological SystemS" is the result of that prestigious conference. Drawing on contributions from nationally recognized scientists and experts from industry and government, this collection of papers covers geochemical and hydrologic processes and provides overall recommendations for conducting environmental research and development during the next twenty years. In addition, the book offers insights on how environmental analyses can be made more reliable. The book covers global cycles, habitat diversity and genetic variability, improved methods for mitigating the environmental impacts of current technologies, and anticipating the environmental impact of emerging technologies, among other topics.

"Environmental Impacts on Human Health"is the result of that prestigious conference. Drawing on contributions from nationally recognized scientists and experts from industry and government, this collection of papers will help to redirect long-term environmental research and development. The book addresses four topic areas: surface and groundwater processes and pollution; land/soil processes and pollution; atmospheric/oceanic processes and pollution; and multimedia toxic substance/hazardous waste research.
