Book Description
This is a report on plants that show promise for improving the quality of life in tropical areas. Because the countries in this zone contain most of the world?s low-income populations this report is addressed to those government administrators, technical assistance personnel, and researchers in agriculture, nutrition and related disciplines who are concerned with helping developing countries achieve a more efficient and balanced exploitation of their biological resources.The 36 plants described here were selected from among 400 nominated by plant scientists around the world. (To keep the project to manageable size, medicinal plants and timber species were excluded.)

Book Description
This is the first book to provide measurements of greenhouse gases from both aquatic and terrestrial environments as well as from hydroelectric reservoirs. This monograph not only presents the state-of-the-art techniques for measuring the emissions of greenhouse gases, but also demonstrates the mechanisms or processes leading to the emissions of greenhouse gases. It offers the reader a synthesis of what we understand of GHG emission after 12 years of research in boreal ecosystems, the estimations of gross and net emissions from hydroelectric reservoirs, the impact of hydroelectric reservoirs on climate change, as well as a comparison of the different alternatives for producing energy in relation to GHG emissions.

Book Description
1.1 Objective and scope These chapters are not intended as a treatise on range management of tropical grazing lands, nor on the agronomy of sown pastures and cultivated fodder crops, aspects of applied science that are only one stage above scientific farming and use of land. An attempt is made to present the vegetation sciences, or botany and ecology in their widest aspects, as the essential background for their application in economic land use and plant and animal husbandry. The basic thesis is that science is global, but that its practical application is restricted to specific biological and socio economic habitats. The region covered is termed the intertropical zone. This comprises the equatorial latitudes, the tropics and subtropics. It is not only that part of the globe lying between latitudes 30° north and south of the Equator, as proposed by some writers (DAVIES, W., 1960; repeated by DAVIES & SKIDMORE, 1966). Rather is it those regions of the world in which, at the lower elevations, certain families and members of the Gramineae and Leguminosae grow wild or can be cultivated. It may be a matter for discussion whether these plants in their wild communities or sown or planted crop mixtures are better indicators of a biological environment than the instruments and criteria of the meteorologists.

Wetlands could be described as land and water at Tropical wetlands: one and the same time, and as such are very specific on the brink ecosystems. Their often rich variety of resources makes them highly valuable to the peoples who live With a few exceptions (like the Everglades in the or regularly stay in them. However, access to them United States), the last remaining large wetlands are to be found in developing countries. Perhaps this can is difficult and those unaware of their services be explained by insufficient financial resources, frequently associate wetlands with such nuisances and calamities as mosquitos, disease, floods, impen lower popUlation density or a different concept of etrable wastelands, etc. As a result these areas are development and well-being. Whatever the reasons, often perceived as obstacles to human development many tropical wetlands still exist and support the and well-being. subsistence of many communities. But for how much History reflects these two views. Wetlands may longer? have been the cradle of great civilizations (like the During the last few decades tropical wetlands Maya, Inca, Aztec, Nilotic and Mesopotamian have also been destroyed or considerably altered. Dams and embankments now prevent water from civilizations), but elsewhere their destruction allowed other societies to develop. For example the Nether spreading into the floodplains of several rivers, like lands literally 'emerged from the waters' thanks to the Senegal, Volta and Nile.

Book Description
It is a privilege to be asked and a pleasurable duty for me to write the foreword of this book. The conservation and wise utilisation of the humid tropical forests, a unique biome, are matters of great concern and importance to millions living within and around these forests and, perhaps, less directly, to the totality of mankind. These forests provide many essential products and services for mankind. The list is lengthy and need not be repeated here. Suffice it to say that there are not many aspects of human activity which do not utilise some of these products, services or derivatives therefrom. Yet it is the view of those most closely associated with the study of these forests that what is known is but a minuscule portion of whatthere is to know. The products and services now utilised, are perhaps some infinitesimal part of the full potential. All over the tropical world, however, these forests are being destroyed. At first, slowly, but now surely gathering tempo. This is true also of Ghana. Tracts offorest land are converted to other uses, often ephemeral and not sustained. Irreversible changes take place in our environment. The gains are shortlived, the losses unobtrusively accumulate and stay forever. The accelerating rate of deforestation, in the face of our relatively scanty knowledge of this biome, is indeed a sad reflection of the state of human affairs. It is in this setting that one welcomes this book by Messrs. J. B. Hall and M. D. Swaine.
