Book Description

Arid Land Irrigation in Developing Countries: Environmental Problems and Effects covers the proceedings of the International Symposium on Arid Land Irrigation, held in Alexandria, Egypt on February 16-21 1976. This book is organized into eight sections encompassing 46 chapters. The opening section deals first with the benefits of arid land irrigation and the effective use of water in irrigated agriculture. This section also tackles the public health and socio-economic impacts of irrigation, as well as the planning and managing of irrigation and drainage systems. The next section discusses the results of some case studies on arid land irrigation, such as in districts in Mexico, Iran, and Egypt. Other sections explore the influence of irrigation on changes in hydrological processes and cycle, soil fertility, water quality, and biological balances. The closing sections consider the human problems in irrigation areas, with an emphasis on the problem of schistosomiasis and malaria. These sections also look into the viewpoints of specialist agencies of the United Nations on arid land irrigation. This book will be of value to agriculturists, economists, and researchers.

Book Description

The international conference Arid Lands: Today and Tomorrow drew more than 400 participants from over 3 S countries to Tucson, Arizona, for one week in October of 19 8 S. The diversity of presenters, disciplines and subject matters addressed contributed to an interesting and informative conference. The papers presented in this volume represent the efforts of scientists and other individuals who, through their various disciplines, are addressing the problems of and opportunities presented by the arid lands of the world. A committee of five scientists reviewed for substance. relevance and their contribution to the conference the 284 abstracts that were submitted. They selected 146 for presentation at the conference and of those papers presented, 128 were received for inclusion in the proceedings.

Book Description

Originally published in 1992, this book dispels some of the myths that surround water resource problems of arid lands and the notion that there are simple ‘once and for all’ solutions. Population growth, industrialization, environmental mismanagement and land degradation have led to droughts, poverty and famine with the result that the need for space, food and key natural resources such as water has become the most critical issue in global development. Nowhere is this crisis more apparent than in arid lands, where water resources provide the key to economic and environmental development. The authors argue that as the arid land environment is highly variable the key to success is flexibility. The book is divided into four sections, dealing with the geography of the arid realm; the water resource problems they face: the methods available for enhancing water supplies and finally, management of this resource. The book will be of use to undergraduate and postgraduate student and for those actively engaged in the development of arid land water resources.

Book Description

Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.

Book Description

This publication contains guidelines to sustain irrigated agriculture and protect water resources from the negative impacts of agricultural drainage water disposal. Using case studies from Central Asia, Egypt, India, Pakistan and the US, this study highlights four broad groups of drainage water management options and provides information to enable assessment of their impact and contribution towards development goals and to facilitate the preparation of drainage water management plans and designs. The options are: water conservation, drainage water re-use, drainage water disposal and drainage water treatment. The full texts of the case studies can be found on the attached CD-ROM.

Book Description

Traditional Arid Lands Agriculture is the first of its kind. Each chapter considers four questions: what we don’t know about specific aspects of traditional agriculture, why we need to know more, how we can know more, and what research questions can be pursued to know more. What is known is presented to provide context for what is unknown. Traditional agriculture, nonindustrial plant cultivation for human use, is practiced worldwide by millions of smallholder farmers in arid lands. Advancing an understanding of traditional agriculture can improve its practice and contribute to understanding the past. Traditional agriculture has been practiced in the U.S. Southwest and northwest Mexico for at least four thousand years and intensely studied for at least one hundred years. What is not known or well-understood about traditional arid lands agriculture in this region has broad application for research, policy, and agricultural practices in arid lands worldwide. The authors represent the disciplines of archaeology, anthropology, agronomy, art, botany, geomorphology, paleoclimatology, and pedology. This multidisciplinary book will engage students, practitioners, scholars, and any interested in understanding and advancing traditional agriculture.

Book Description

This revised and updated new edition retains the clear and powerful argument which characterized the original. It gives a valuable analysis of the theory and practice of sustainable development and suggests that at the start of the new millennium, we should think radically about the challenge of sustainability. Fully revised, this latest edition includes further reading, chapter outlines, chapter summaries and new discussion topics, and explores: the roots of sustainable development thinking and its evolution in the last three decades of the twentieth century the dominant ideas within mainstream sustainable development the nature and diversity of alternative ideas about sustainability the problems of environmental degradation and the environmental impacts of development strategies for building sustainability in development from above and below. Offering a synthesis of theoretical ideas on sustainability based on the industrialized economies of the North and the practical, applied ideas in the South which tend to ignore 'First World' theory, this important text gives a clear discussion of theory and extensive practical insights drawn from Africa, Latin America and Asia.

Book Description

Three themes run through this book, the first is the history of the Nile; the second is the degree to which the present Sudanese landscape reflects the operation of former geological processes; the third is the interaction between man and environment, not always to the benefit of either. A land between two Niles is an interdisciplinary account of the origins and characteristics of the alluvial plains of the lower Blue and White Nile. The contributors have focussed their attention upon this region for several reasons. Although the Gezira plain itself only occupies about one percent of the total area of the Sudan, the high quality long-staple cotton grown there provides nearly two-thirds of the country’s total export revenue.
