Description

Food and Natural Resources provides an understanding of the interdependency of food and natural resources that affect society. It is hoped that through these discussions a more complete understanding of these timely issues will emerge. This base of knowledge will help individuals and government leaders develop and implement the types of programs that will result in the effective use and management of land, water, energy, and biological resources for improved food production and a higher standard of living for everyone. The book begins by examining the intrinsic dynamics of natural ecosystems—especially the land, water, atmosphere, energy, and biological components. This is followed by chapters on the availability and interrelationships between population size, arable land, water, energy, and other biological resources; the loss of wild species of plants and animals; the availability of agricultural land for crops and livestock; and the impact of land degradation on food and other resources. Subsequent chapters discuss water use in agriculture; the mechanization of agriculture and food production; the principles and practices that can make agriculture environmentally and economically sound and sustainable; and the impact of population growth on the environment and food supply.
