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.

Community-oriented conservation of natural resources and promotion and protection of trees in drylands are examples to deal with climatic adversities. This book provides knowledge on climatic, ecological, social and economic condition of dry areas and lay out approaches and strategies to restore degraded lands. There are 15 chapters and first five deals with physiography of Rajasthan, drylands ecology, problems of land degradation, its economic evaluation and the approaches and strategies of restoration and rehabilitation. Next two chapters describe the problems of sand drift, salinity, water logging and effluent inflicted areas and strategies to control them. Chapters 8-10 deal with seed production, quality planting materials, genetic improvement, propagation and planting techniques. Chapters 11-12 describe methods of rain water harvesting and irrigation, and resources conservation for seed sowing and favouring regeneration and successions. Effective management of pests/diseases in nurseries and plantation, growth and yield prediction equations and models, and people's perception and participation in managing forest resources have been described in last 3 chapters. Purpose of this publication is to strengthen the forest functionaries and readers with wide ranging knowledge on land degradation, desertification and eco-biology of drylands; and methods to restore and rehabilitate degrading forest (lands) to increase forest cover, enhance resilience and people livelihoods and improve environmental conditions. Academician, researchers, forest managers, non-government organizations, extension agents and environmentalists can use it in developing, conserving and managing drylands ecosystems for its long lasting beneficial effects. This book is also useful to policy makers in effective planning of restoring, protecting and conserving dryland's ecological and socioeconomic services.

The book is a comprehensive manual of practice for execution of afforestation and tree planting programmes in arid and semi-arid tropics. It includes a compact running account of the technology of afforestation and the relevant principles and practices in management of afforestation projects. It provides a wide range of structured information and a number of model designs which can be gainfully put to use by the field level supervisors as also by the managers concerned with planning and control of such projects. Written by a practising specialist, the book is invaluable for anyone concerned with the practice of afforestation and tree planting, be he a tree hobbyist or a school teacher, a professional forester or a senior policy maker in government, an industrialist or a philanthropist, an environmental activist or a member of a community service organization.

Ecosystem Science is a highly interdisciplinary field of global significance. This series - copublished by Higher Education Press (HEP) and De Gruyter Publishers - is devoted to prominent topics in the fundamentals of ecosystem science and its application. The series is targeted to an international audience of scientists and practitioners, while maintaining a strong emphasis on reaching scholars and the general public in China. This will be accomplished by publishing all ESA books in both English and Chinese.

An argument that the perception of arid lands as wastelands is politically motivated and that these landscapes are variable, biodiverse ecosystems, whose inhabitants must be empowered. Deserts are commonly imagined as barren, defiled, worthless places, wastelands in need of development. This understanding has fueled extensive anti-desertification efforts—a multimillion-dollar global campaign driven by perceptions of a looming crisis. In this book, Diana Davis argues that estimates of desertification have been significantly exaggerated and that deserts and drylands—which constitute about 41% of the earth's landmass—are actually resilient and biodiverse environments in which a great many indigenous people have long lived sustainably. Meanwhile, contemporary arid lands development programs and anti-desertification efforts have met with little success. As Davis explains, these environments are not governed by the equilibrium ecological dynamics that apply in most other regions. Davis shows that our notion of the arid lands as wastelands derives largely from politically motivated Anglo-European colonial assumptions that these regions had been laid waste by “traditional” uses of the land. Unfortunately, such assumptions still frequently inform policy. Drawing on political ecology and environmental history, Davis traces changes in our understanding of deserts, from the benign views of the classical era to Christian associations of the desert with sinful activities to later (neo)colonial assumptions of destruction. She further explains how our thinking about deserts is problematically related to our conceptions of forests and desiccation. Davis concludes that a new understanding of the arid lands as healthy, natural, but variable ecosystems that do not necessarily need improvement or development will facilitate a more sustainable future for the world's magnificent drylands.
