Book Description
Fifteen years ago, approximately half the world population was estimated to live in continental and insular South-East Asia (Burma, Thailand, Kampuchea, Vietnam, Laos, Indonesia, Philippines). Then the region had a population growth of four million people every month, and the problem of malnutrition was acute for the rural population. International agricultural development organisations decided that their primary aim would be to double existing levels of agricultural production and, taking account of population growth, to double it again by the end of the century (Whyte 1976). Today, while global issues have greatly affected the parameters of the problem, the situation remains both serious and difficult. Despite impressive efforts in education and health, Indonesia for example, where population (179 millions) growth eased off only slightly between 1980 and 1990 (from 2. 3 percent to 1. 9 percent), is having to cope with increasing difficulties in managing natural resources and particularly its evanescent forest assets which, until 1986, were the second largest source of national revenue. Indonesia has the second largest surface area of tropical rain forests in the world (after Brazil) and thus all the problems linked with management and disappearance of those forests. The latest estimate gives a figure of 109 million hectares of forest in 1990, of which 40. 8 million hectares are production forests (Anon. -F AO 1990).

Book Description
The rise of American geography as a distinctive science in the United States straddles the 19th and 20th centuries, extending from the post-Civil war period to 1970. American Geography and Geographers: Toward Geographic Science is the first book to thoroughly and richly explicate this history. Its author, Geoffrey J. Martin, the foremost historian on the subject and official archivist of the Association of American Geographers, amassed a wealth of primary sources from archives worldwide, which enable him to chart the evolution of American geography with unprecedented detail and context. From the initial influence of the German school to the emergence of Geography as a unique discipline in American universities and thereafter, Martin clarifies the what, how and when of each advancement. Expansive discussion of the arguments made, controversies ignited and research voyages move hand in hand with the principals who originated and animated them: Davis, Jefferson, Huntington, Bowman, Johnson, Sauer, Hartshorne, and many more. From their grasp of local, regional, global and cultural phenomena, geographers also played pivotal roles in world historical events, including the two world wars and their treaties, as the US became the dominant global power. American Geography and Geographers: Toward Geographical Science is a conclusive study of the birth and maturation of the science. It will be of interest to geographers, teachers and students of geography, and all those compelled by the story of American Geography and those who founded and developed it.

Book Description
The analysis and management of ecosystems rely increasingly on sound geographical knowledge. Ecosystem Geography is a landmark contribution which brings the geographer's tools - maps, scales, boundaries, and units - to the study of ecosystems. The author, a senior geographer and program manager with the U.S. Forest Service, has distilled more than two decades of research on ecosystem mapping and classification. His work has had a growing influence on how government and academic scientists are using ecological data to monitor biodiversity, manage land holdings, and interpret the results of climatic change. Ecosystem Geography features spectacular graphics, including diagrams, photographs, and abundant maps. It will be welcomed by ecologists, geographers, land and resource specialists, and anyone involved in the study of ecosystems.
