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
An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics. Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and agroforestry systems as well as ecosystem studies from the dipterocarp forest region of Southeast Asia. Additionally, case studies include work from Guyana, Costa Rica, the Philippines, Malaysia, Australia and Nigeria.

Book Description
The Ecology of Sumatra distills for the first time the information found in nearly 1,500 scholarly works relevant to an understanding of the full range of natural and man-made ecosystems on the island—many of them available only in Dutch, German or Indonesian. It was originally prepared by a team working at the Centre for Resource and Environmental Studies (CRES) at the University of North Sumatra to supplement existing documents. This new version is aimed at general readers and includes a section on recent development on Sumatra, as well as an additional bibliography of recent publications. It contains hundreds of line drawings, tables, maps and photographs. It is hoped that The Ecology of Sumatra will prove useful to resource managers, ecologists, environmental scientists and local government personnel, and be enlightening to Sumatra’s inhabitants and visitors. It should also be of great interest to anyone wanting to learn about Southeast Asian biology.

Book Description
In this translation of the French edition (L'U. de Saint-'etienne, 1999), the author treats the interrelated factors that inform plants' adaptations to their environments. Applying ecophysiological principles to identify mechanisms of dysfunction in ecosystems, he presents data-based cases for: less stressful growing methods (e.g., using cultivars
