Book Description
This volume is a synthesis of the NASA funded work under the Land-Cover and Land-Use Change Program. Hundreds of scientists have worked for the past eight years to understand one of the most important forces that is changing our planet-human impacts on land cover, that is land use. Its contributions span the natural and the social sciences, and apply state-of-the-art techniques for understanding the earth: satellite remote sensing, geographic information systems, modeling, and advanced computing. It brings together detailed case studies, regional analyses, and globally scaled mapping efforts. This is the most organized effort made to understand the dominant force that has been responsible for changing the Earth’s biosphere. Audience: This publication will be of interest to students, scientists, and policy makers. This volume includes a CD-ROM containing full color images of a selection of illustrations which are printed in black-and-white in the book.

Book Description
Tropical forests are vital for social, economic and ecological reasons. They play an important role in ecosystem processes [ such as the biogeochemical and hydrological cycle ] they provide habitat for wildlife and serve as source of biodiversity and they offer protection against soil erosion [Kremen et al., 2000 and Condit et al., 2002]. The forest contains large trees standing, 30 to 50 meters in height, creating continuous canopy of foliage. The enclosed canopy, shades tree forest floor, inhibiting the development of much undergrowth, creating an open forest formation. Piercing into the tree canopy, reveals a multistory appearance of broad leaf, evergreen vegetation. The forest is a treasure trove of different animal and plant species. Forest and woodlands cover nearly 40% of the earth’s land surface and they are the most biologically diverse ecosystems in most part of the world. The tropics consist of a diversity, occurring between the latitudes of the tropic of Cancer and the tropics of Capricon, north and south of the equator. These ecosystems are currently experiencing the highest rates of destruction in the world. More than 90% of dry forests have been destroyed and less than 2% of what remains is protected. Because of the climatic and forest structure, dry forests are easier to clear for agriculture, the soil is more fertile and the land is more suitable for livestock. Forest area has increased slightly since 1980 in industrial countries, but, has declined by almost 10% in developing countries. Tropical deforestation probably exceeds 1,30,000 sq. km a year. Less than 40% of forest globally are relatively undisturbed by human action. Many developing countries today, rely on timber for export earnings, at the same time; millions of people in tropical countries still depend on forests to meet their every need. Since time immemorial, forest has provided a valuable source of economic life for human populations. Yet, the ways in which, forests are used and valued, depends largely on people’s economic needs and priorities in a particular place or at a particular time, balanced against the relative scarcity or abundance of forest resources. Over recent years, a complex array of social, economic and political changes have altered human demands on forest. These changing demands have had devastating impact on forest status and integrity. This book is an outcome of the own work, experience and research on tropical forest for the last 30 years. I hope, this will provide to readers, concise, sufficient and recent information on tropical forest of the world.
