The increasing world population is already causing intensive pressure on the most productive areas of the earth's surface. Hopes of improved living standards, if realised, will increase the pressure still further. The need to make better use of less productive areas thus becomes an urgent priority for human endeavour. In this respect, the arid and semi-arid regions of the world, occupying about 11,000 million acres or 4,500 million hectares, roughly one third of the tota11and surface, pose a constant challenge to man's technological skill. Though the possibilities of economic use of the real deserts are inherently limited, there remain vast areas with less extreme conditions where sustained research is capable of yielding substantial gains in pro ductivity. The problem is so large that it can be solved only by the coordinated efforts of workers in many countries and many disciplines. Forestry has a special part to play, not only for its potential value for wood production but still more for the beneficial effects of shelter from desiccating winds which so commonly accompany arid conditions. Mr. KA UL is to be congratulated on his initiative to pool the results of research on afforestation in arid zones in many parts of the world, and to present them in a single volume in the form of separate monographs.

This book is comprehensive source of information on afforestation techniques in arid zones by suitably planning afforestation techniques such as selection of seeds both indigenous and exotic, soil. Working techniques and cultural operations in relation to harnessing otherwise uncertain and erratic rainfall, particular during the period when lack of the soil moisture is must felt and protection against disease and vertebrate pest in hot and cold arid zones. Study on climate, physiology, geology, hydrology, land use patterns, seedling studies, silvicultural characters, of trees and shrub species and their experimental aspects and results in discussed in full in this book by the leading authorities of the world.This is useful reference book to the scientists, researchers, forest officers, students, scholars and should be possessed by the libraries.

The Role of Science in the Development of Natural Resources with Particular Reference to Pakistan, Iran and Turkey is a collection of papers that details issues in power and energy, water resources, forestry and land, agriculture, animal health, and public health. The materials analyze the problems in natural resource from different scientific perspectives. The text first coves the place of research in developing countries, and then proceeds to tackling concerns in fuel, power, and atomic energy. Next, the selection talks about the development of water resources. The next sections of the text deal with forestry and agriculture. The selection also covers concerns in animal and public health. The book will be of great interest to individuals concerned with the condition of world’s natural resource reserves.

In large areas of developing countries the loss of trees is causing erosion and degradation of the soil, posing severe problems for economic development. By translating the ecological benefits of afforestation into economic terms, the author demonstrates how investments that benefit the environment often benefit the economy as well. Both the traditional work of the forestry services and tree plantings by farmers are needed, says the author, if deforestation is to be halted and reversed. With special refrence to Africa, he discusses the underlying reasons for deforestation, suggests policy changes to promote the planting and care of trees, and identifies issues for social and scientific research. A case study of the arid zone of northern Nigeria illustrates the benefits that could be brought about by establishing windbreaks and encouraging farmers to plant trees. Besides preventing soil erosion, improving soil fertility, and thus increasing crop prodution, trees provide fruit, livestock fodder, and much-needed fuelwood and building materials. The author compares the increase in farm incomes as a result of an afforestation program with the decrease in incomes if deforestation and soil erosion were to continue. The analysis will be of special interest to those concerned with agriculture, forestry, rural development, and environmental issues in developing countries.
