This irrigation and drainage paper is intended to provide guidance to national planners and decision-makers, agricultural and municipal managers, field engineers and scientists, health and agricultural field workers, wastewater treatment plant operators and farmers. Consequently, it covers a broad range of relevant material, some in considerable depth but some more superficially. It is meant to encourage the collection, treatment and use of wastewater in agriculture in a safe manner, with maximum advantage taken of this resource. Informal, unplanned and un-organized waste water use is not recommended, nor it is considered advisable from the health or agricultural points of view.

This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

In recent times, the coalescence of different pressure has put a major strain on water supply globally. The level of water abstraction is reaching its natural limits, and this calls for a dramatic shift in water utilization concepts. This publication addresses the economic and financial issues and the methodology and procedures involved in the analysis of water recycling projects as part of a comprehensive water planning process. The issue is dealt within the wider context of water resources and covers human health, water quality, acceptability, institutional constraints, and other factors, all of which have economic implications and affect the feasibility of reuse schemes. The recycling of urban wastewater is a key link in Integrated Water Resource Management that can fulfill several different, but interrelated objectives. These are expressed as win-win propositions, delivering simultaneous benefits to farmers, cities and natural environmental systems, part of solutions to the urgent global problems of food, clean water, the safe disposal of waters and the protection of the vital aquatic ecosystems.

This book presents a conceptual and practical tool for those involved directly or indirectly in the planning and management of basic provision of water supply, wastewater and stormwater services in metropolitan regions by offering insights into governance paradigms and institutional arrangements for urban wastewater reuse in agriculture from Australia and India. Instead of focusing on the technical aspects of designing and building infrastructure, it provides a better understanding of the institutional and governance challenges of managing urban wastewater, particularly for reuse in agriculture. As water supplies fall and water stress increases in many areas, the potential of wastewater as a resource is being widely recognized. Today, wastewater (re)use has become an attractive option for conserving and expanding available water supplies. While wastewater (re)use can have many applications, its use in agriculture is the most established, and the one with the longest tradition. Given the growing competition for freshwater from industry and cities, without doubt there is going to be a rapid increase in the global use of treated wastewater, making improved wastewater use in agriculture an emerging priority. Even though it is a vast resource if we reclaim it properly, often most wastewater is wasted. Therefore, in order to realize the full potential of this resource, decision support in policy design and implementation (Institutions and Governance) is key. Institutions and governance frameworks need to provide for the rights of access, rights of ownership, rights to manage source and treated water and the obligations of final use of recycling operations.

The objective of this paper is to provide a review of the characteristics of wastewater used for irrigation, and the reasoning behind the international guidelines presently used in regulating wastewater reuse for agriculture. This paper presents various systems of wastewater treatment available and discusses their benefits and shortcomings. A selective review of recent empirical studies identifies major impacts both positive and negative impacts of wastewater irrigation. Finally, the paper provides the review of environmental valuation techniques for analyzing impacts of wastewater uses in agriculture, and suggest a framework for application of some of these techniques. This framework will be applied to a developing country case study (Faisalabad area in Pakistan), in the ongoing IWMI research program.

In the countries of the Middle East and Northern Africa, reclaimed wastewater is recognized as a non-conventional water resource. However, substandial amounts are still discharged into water courses without further treatment. The objective of this research was to analyse the technological, regulatory, institutional, financial and socio-cultural opportunities, seen as incentives; and the constraints, perceived as disincentives, which influence the adoption of wastewater treatment and reuse. Fieldwork was carried out in Jordan and Tunisia, countries which have made great strides in raising the proportion of re-used wastewater. Unexpectedly, farmers and customers proved well-prepared to use reclaimed water in irrigation, and to buy crops raised in the irrigated fields. Abu-Madi stresses the need for raising the price of freshwater, reflecting its true scarcity, thus creating a stronger incentive to utilise reclaimed wastewater.

"The MENA region is the driest in the world. Irrigated agriculture consumes the largest volume of water resources due to the continuous demand for food production. A huge potential for satisfying this increasing demand exists in the reuse of municipal wastewater in agriculture. This book emphasizes the importance of appropriate water policies and the enabling institutional setting in successful wastewater management and reuse. The in-depth-analysis is presented through the case study of Jordan."--Page 4 of cover.

The purpose of this study is to provide an updated and comprehensive database of information on the status and progresses made on the use of treated wastewater in Lebanon, to highlight data gaps and inconsistencies, and assess the potentialities of TWW using a case study approach in Caza (Province) through a GIS multilayer analysis. The study is based on the work of the FAO project 'Coping with water scarcity - the role of agriculture – Phase III', active in Lebanon since 2011, which seeks to st rengthen the safe use of treated wastewater in agriculture and deals with the agricultural component of water scarcity. The study also presents a tool to support the Government of Lebanon to meet its stated objectives for agricultural water management and to develop new policies on the use of TWW. It will further contribute to the achievement of a number of existing national strategies relating to water, agriculture, environmental management and desertification.
