Klappentext With a decrease in per capita land area! increasingly severe soil degradation! and rising global temperatures! the dependence of food security on soil quality is likely to increase exponentially. Food Security and Soil Quality collates! reviews! and synthesizes the available research information on food security and soil quality at a regional scale. It discusses the global food crisis and the impact of soil quality and how soil quality relates to climate change and agronomic productivity. This book is a useful resource for those involved with agriculture! environmental science! natural resources! and food and resource economics. Zusammenfassung The UN Millennium Development Goals' intent to halve hunger by 2015 will not be realized. This title presents an exploration of the problem at hand and the critical steps needed to reverse it. It examines concerns with and approaches to soil quality management in Brazil and China.
