Sustainability in Irrigated Agriculture


Book Description

This short paper attempts to bring some focus to the discussion, particularly as it concerns irrigated agriculture, by suggesting some central features which characterize the notion of "sustainability" and by suggesting several dimensions which help to define it. In the particular three broad categories are suggested or discussion.




Sustainability of Irrigated Agriculture


Book Description

Irrigated agriculture and the use of water resources in agriculture face the challenges of sustainable development. Research has advanced our knowledge of water use by crops, soil-water-solutes interactions, and the engineering and managerial tools needed to mobilize, convey, distribute, control and apply water for agricultural production. However, the achievements booked in user practice have revealed the need for new developments in the areas of resource conservation, control of environmental and health impacts, modernisation of technologies and management, economic viability and the social acceptance of changes. The contributions to Sustainability of Irrigated Agriculture cover most of the relevant disciplines. Besides its multidisciplinarity, the different origins, experience, backgrounds and practices of the authors provide a wide, in-depth analysis of the various aspects of water resource utilization in agriculture. The papers review scientific, technical and managerial aspects, highlighting the main problems, issues and future developments. The book covers the different aspects of sustainability, including environmental, technical, economic, institutional and social ones. Advances in irrigation science and engineering are dealt with, both on- and off-farm. Special attention is paid to the different components of water quality management, to the transfer of technology, and to capacity building.







Water and Sustainable Agriculture


Book Description

Irrigated agriculture, a vital component of general agriculture, supplies fruits, vegetables, and cereals consumed by humans and grains fed to animals. Consequently, agriculture is the largest user of fresh water globally, and irrigation practices in many parts of the world are biologically, economically, and socially unsustainable. Water management should balance the need for agricultural water and the need for a sustainable environment. Water-use efficiency is the prime challenge in worldwide farming practices where problems of water shortages are widespread. Currently, agriculture is undergoing significant changes in innovative irrigation, fertilizer technology, and agronomic expertise. These elements constitute a vital platform for sustainable agricultural success and for preventing environmental damage. This review presents several processes linked to environmental irrigation, balancing environmental protection with improved agricultural production.




Salinity Management for Sustainable Irrigation


Book Description

Irrigation has long played a key role in feeding expanding populations and is expected to play a still greater role in the future. However, is it sustainable? Can it remain in existence and function continuously and indefinitely? Some pessimists doubt that it is. This volume presents a more positive approach with carefully conditional optimism. It takes the diffuse, voluminous and disparate facts and combines them in a unified exposition. It merges physico-chemical, agronomic, environmental and economic principles into practical recommendations to help ensure the long-term viability and productivity of irrigated agriculture in arid and semiarid regions.




Sustainable Irrigation Management, Technologies and Policies


Book Description

Fresh water is becoming an ever increasingly precious commodity, control of which could lead in the near future to the type of political instability now associated with energy shortages. This book addresses the different aspects of irrigation, including not only the management of water resources and scientific and technical aspects, but also matters related to policy and economics, researchers in academia and industry as well as professional practitioners and policy makers. Bringing together papers from the First International Conference on Sustainable Irrigation Management, Technologies and Policies, the book covers topics such as: Irrigation Controls; Irrigation Modelling; Irrigation Systems and Planning; Irrigation Management.




Optimal Water Management and Sustainability in Irrigated Agriculture


Book Description

As the global demand for food continues to rise, it is crucial to ensure that our agricultural practices are sustainable and efficient, especially when it comes to water management in irrigated agriculture. The sustainability of irrigated agriculture requires the efficient management of the available but limited water resources under the existing constraints. Water demand in irrigation is expected to increase in the near future, and it will be seriously impacted by climate change, especially in arid and semi-arid areas. The irrigation water-use efficiency is key to addressing water shortages and reducing environmental problems. In this context, robust and optimal approaches are used to improve irrigation water efficiency, energy use, and crop productivity, and to mitigate economic losses from water scarcity. The SI brings together 14 research papers addressing various water management aspects in irrigated agriculture. The Issue covers a range of topics such as (a) sustainable practices and crop sequencing, (b) irrigation scheduling and deficit water irrigation, (c) the hydrochemical assessment of water, (d) fertigation and irrigation, and (e) forecasting techniques of reference evapotranspiration.







Irrigated Agriculture in Egypt


Book Description

This book targets the issue of water scarcity in Egypt as a typical example of the world water crisis. Today, the available water resource is facing its limit because of rapid increase in water demand as a result of population growth and changes in peoples’ life-style. The basic idea to solve the problem of water scarcity is that the irrigation sector, the biggest user of water, should increase water use efficiency. However, the real problem is how this can be achieved in view of the crucial need for water in this sector. This book addresses this challenge through case studies from the Nile delta in Egypt. The water problem in the Nile delta, the major source for water in Egypt, is discussed in this book from all its various aspects. This book covers the situation before and after the advent of the Aswan High Dam, so that the reader understands the entire development. Another special feature are the extensive and scientific descriptions of contemporary topics in water and agriculture, especially from the viewpoint of water saving and sustainability. These descriptions are based on field experiments and surveys in a six-year international research project. Topics of this book are local, but their implications are global.
