The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.

Nestled between the Rocky Mountains to the west and the High Plains to the east, Denver, Colorado, is nicknamed the Mile High City because its official elevation is exactly one mile above sea level. Over the past ten years, it has also been one of the country's fastest-growing metropolitan areas. In Denver's early days, its geographic proximity to the mineral-rich mountains attracted miners, and gold and silver booms and busts played a large role in its economic success. Today, its central location—between the west and east coasts and between major cities of the Midwest—makes it a key node for the distribution of goods and services as well as an optimal site for federal agencies and telecommunications companies. In Metropolitan Denver, Andrew R. Goetz and E. Eric Boschmann show how the city evolved from its origins as a mining town into a cosmopolitan metropolis. They chart the foundations of Denver's recent economic development—from mining and agriculture to energy, defense, and technology—and examine the challenges engendered by a postwar population explosion that led to increasing income inequality and rapid growth in the number of Latino residents. Highlighting the risks and rewards of regional collaboration in municipal governance, Goetz and Boschmann recount public works projects such as the construction of the Denver International Airport and explore the smart growth movement that shifted development from postwar low-density, automobile-based, suburban and exurban sprawl to higher-density, mixed use, transit-oriented urban centers. Because of its proximity to the mountains and generally sunny weather, Denver has a reputation as a very active, outdoor-oriented city and a desirable place to live and work. Metropolitan Denver reveals the purposeful civic decisions made regarding tourism, downtown urban revitalization, and cultural-led economic development that make the city a destination.
