Supplemental Irrigation in the Near East and North Africa


Book Description

This book is the product of an ICARDA project to define supplemental irrigation in the Near East and North Africa. In cooperation with the Food and Agriculture Organization of the United Nations (F AO) a meeting was held in Rabat, Morocco, on 7-9 December 1987, entitled "Regional Consultation on Supplemental Irrigation"; specialists from 11 different countries were brought together to discuss priorities for supplemental irrigation within their specific regions. The participants were asked to focus on developing an information base using both primary data, results of surveys administered to district level agricultural personnel, and secondary data sources with a particular interest in the application of state-of-the-art knowledge and technology to the problems of supplemental irrigation. The authors have willingly and thankfully responded to the suggestions and criticisms of Ms Kate Ward, Institute of Irrigation Studies, Department of Civil of Southampton, U. K. , who accepted the soporific Engineering, University position of Review Editor and performed miracles. Chapter 2 and parts of chapters 15 and 16 are a partial rendering of a forthcoming book on systems analysis by Janice R. Perrier. The authors recognize the inclusion of this material which outlines the basic philosophical perspective of supplemental irrigation as utilized in the book. The assistance of Mr. Maurice Saade, Agricultural Economist is greatly appreciated for the understanding of Chapter 14. The section on the phenology of cereals near the end of chapter 4 was written by Mr.










Rainfed Agriculture


Book Description

Rainfed agriculture is generally overlooked by development investors, researchers and policy makers due to limited confidence in its ability to increase agricultural production and development. However, research undertaken by a team of leading scientists from global organizations demonstrates its potential in achieving food security, improving livelihoods and most importantly addressing issues of equity and poverty reduction in dryland areas - the hot spots of poverty. On the basis of case studies from varied agricultural and ecological regions in Asia and Africa, chapters discuss the need for adopting new paradigms between rainfed and irrigated agriculture, catchment/micro-watershed management approaches, upgrades in science-based development and more investments in rainfed areas. Yield gaps for major rainfed crops are analysed globally and possible ways and means including technological, social, and institutional options to bridge the yield gaps are discussed in detail. Covering areas such as rainwater harvesting and its efficient use, the rehabilitation of degraded land and assessment methods for social, environmental and economic impacts, this book will be necessary for both academics and policy makers working in water management, agriculture and sustainable development.




Sustainable Intensification of Crop Production


Book Description

This book outlines a new paradigm, Sustainable Intensification of Crop Production (SICP), which aims to produce more from the same area of land by increasing efficiency, reducing waste, conserving resources, reducing negative impacts on the environment and enhancing the provision of ecosystem services. The use of ecologically based management strategies can increase the sustainability of agricultural production while reducing off-site consequences. The book also highlights the underlying principles and outlines some of the key management practices and technologies – such as minimum soil disturbance; permanent organic soil covers; species diversification; selection of suitable cultivars, planting time, age and spacing; balanced plant nutrition; agro-ecological pest management; efficient water management; careful management of farm machinery; and integrated crop-livestock production – required to implement SICP. The green revolution (by using high-yielding crop varieties, mono-cropping, fertilization, irrigation, and pesticides) has led to enormous gains in food production and improved world food security. In many countries, however, intensive crop production has had negative impacts on production, ecosystems and the larger environment, putting future productivity at risk. In order to meet the projected demands of a growing population expected to exceed 9 billion by 2050, farmers in the developing world must double food production, a challenge complicated by the effects of climate change and growing competition for land, water and energy. This book will be of immense value to all members of the scientific community involved in teaching, research and extension activities concerning sustainable intensification. The material can be used for teaching post-graduate courses, or as a useful reference guide for policy makers.
