Salinisation of land and water is an increasing problem in many areas of the world, particularly in arid and semi-arid regions where irrigation is a contributory factor. This book assesses the extent, human causes and management of salinisation. The first part of the book provides an extended review of general issues, including a history of secondary salinisation, followed by a discussion of the trends in area irrigated, the process of salinisation, extent of land and water salinisation and thei...

Effective communications in all stages of the project cycle (including identification, preparation, implementation and operation) are critical to the success of complex hydraulic infrastructure projects, involving many stakeholders. Being the largest binational water transfer scheme in the world and because of its phasing, the lessons learned in this case study are multifaceted. The LHWP can serve as a model of mutually beneficial development--through demonstrating the benefits of bilateral gove...

In many countries, investments in agricultural water management are seen as a key element of rural development and poverty reduction strategies, but they are often costly. Planning such investments requires a good overview of their benefits and costs and of their sustainability. Guidance is further needed in answering the following three questions: i) where to invest?, ii) who will benefit?, iii) what typology of investment is most appropriate? This report describes a methodology to conduct rapi...

This outstanding reference book deals with effects of various agricultural practices on ground water quality and usage; and ground water management strategies for protection of ground water affected by agriculture.

While addressing the issues of using groundwater in agriculture for irrigation in the developing world, this book discusses the problems associated with the degradation and overexploitation of using it. It explores the practiced and potential methods for its management in the context of agricultural development.

The AQUASTAT Programme was initiated with a view to presenting a comprehensive picture of water resources and irrigation in the countries of Africa, Asia, Latin America and the Caribbean and providing systematic, up-to-date and reliable information on water for agriculture and rural development. This report presents the results of the most recent survey carried out in the 18 countries of the Middle East region, and it analyses the changes that have occurred in the ten years since the first surve...

The guide provides a comprehensive list of issues that should be addressed in operation and maintenance manuals for irrigation and drainage systems, and a listing of published materials and...

Irrigation has been and will continue to be an agricultural and rural investment priority. Development of the irrigation sector faces multiple challenges, including water scarcity and degradation, competition over shared resources, and the impact of climate change. Innovations are needed to address these challenges, as well as emerging needs, and to promote productive, equitable and sustainable water management. These guidelines, produced by an inter-agency team, highlight experiences and lesson...

Water resources are under tremendous pressure due to growing demand, climate change and anthropogenic pollution in Lebanon. Rapidly declining water quality is a key indicator of the water resource degradation that characterizes now both the freshwater and marine environment across the country. The project "Improved Water Resources Monitoring System/Integrated Water Resources Management at regional level in Lebanon", funded by the Swiss Government, is designed to establish a comprehensive water m...
