The practice of using untreated wastewater for irrigation is widespread but has been largely ignored because the norm has always been that wastewater should be treated before use. Increasing water scarcity, lack of money for treatment and a clear willingness by farmers to use untreated wastewater have led to an uncontrolled expansion of wastewater use. It is therefore important to better document the practice of irrigation with untreated wastewater in order to find out how it can be improved within the financial possibilities of very low-income countries.

Farming communities in water-scarce regions increasingly practice the use of urban wastewater in agriculture. Untreated urban wastewater is generally considered unacceptable for direct use because of potential health risks. However, in many parts of the world, poor farmers in peri-urban areas use untreated wastewater. This situation is considered likely to continue even in the foreseeable future due to the high investment cost associated with the installation of treatment facilities.

The books provides a timely analysis in support of a paradigm shift in the field of wastewater management, from ‘treatment for disposal’ to ‘treatment for reuse’ by offering a variety of value propositions for water, nutrient and energy recovery which can support cost savings, cost recovery, and profits, in a sector that traditionally relies on public funding. The book provides new insights into the economics of wastewater use, applicable to developed and developing countries striving to transform wastewater from an unpleasant liability to a valuable asset and recasting urbanization from a daunting challenge into a resource recovery opportunity. “It requires business thinking to transform septage and sewage into valuable products. A must read for water scholars, policy makers, practitioners, and entrepreneurs". Guy Hutton, Senior Economist, Water and Sanitation Program, Water Global Practice, World Bank “This book provides compelling evidence and real solutions for the new ‘resource from waste’ approach that is transforming sanitation, boosting livelihoods, and strengthening urban resilience”. Christopher Scott, Professor and Distinguished Scholar, University of Arizona “This book shows how innovative business thinking and partnerships around resource recovery and reuse fit well within an inclusive green economy and climate change adaptation and mitigation strategies”.

Like in many parts of the world, water resources in sub-Saharan Africa (SSA) have been pivotal for human survival, economic growth, social development, and practicing certain religion and cultural ethos. However, in spite of the intrinsic values of water, its use and management in sub-Saharan Africa has not been without limitations. The demand for water resources is increasing mainly due to rapid population growth, industrialization and urbanization and dealing with water-related issues has been complex and challenging for sustainable growth. Whilst there are various efforts by national governments, non-government organizations and communities to effectively and efficiently utilize and manage water resources, there are few comprehensive studies in sub- Saharan Africa that show the impact of the efforts on poverty reduction. Although certain reports indicate that many SSA countries lack clear vision on how water use can be harnessed with pro-poor growth and how poor communities can be capacitated to use water for poverty reduction, there are little exhaustive studies that clearly show familiar and innovative water use and management interventions followed by communities, national governments and other stakeholders, and demonstrate the challenges and successes of the same. Cognizant of the knowledge gap, in 2012 OSSREA launched a research project on ordinary and innovative water use and management patterns and practices in SSA, with a view to generate new knowledge on unexploited opportunities that could enhance the contribution of water resources to poverty reduction. This anthology documents various issues including water use and management in agriculture especially in irrigation projects in Ethiopia, Kenya, Uganda and Zimbabwe; water harvesting in Kenya and Uganda; the role of local water use institutions in Ethiopia; and water source maintenance and protection in Uganda.

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.

Soil and water salinity is a major challenge for the agricultural community and policy makers in terms of meeting the burgeoning population’s demand for food and other agricultural commodities. In coastal regions, climate change and sea level rise will aggravate the problem with more and more areas becoming saline due to intrusion of sea water. As such there is a pressing need for modern tools and innovative techniques for the identification of salty soils and poor-quality waters, crop production, soil reclamation and lowering the water table in waterlogged areas. Tackling next-generation problems such as contamination of soil and underground water due to fluoride and arsenic, as well as developing multi-stress tolerant crops is also a high priority. Further, techniques for domesticating halophytes, mangrove-based aquacultures, using seaweed cultures as agricultural crops and integrated farming systems need to be perfected. This book addresses all these aspects in detail, highlighting the diverse solutions to tackle the complex problem of salinity and waterlogging and safer management of poor-quality waters. With chapters written by leading experts, it is a valuable resource for researchers planning future investigations, policy makers, farmers and other stakeholders, and for students wanting insights into vital issues of environment.

Global trends such as urbanization, demographic and climate change that are currently underway pose serious challenges to sustainable development and integrated resources management. The complex relations between demands, resource availability and quality and financial and physical constraints can be addressed by knowledge based policies and reform of professional practice. The nexus approach recognizes the urgent need for this knowledge and its interpretation in a policy- relevant setting that is guided by the understanding that there is a lack of blueprints for development based on integrated management of water, soil and waste resources in the Member States. Generation and application of knowledge is both a priority for individual but also institutional capacity development.
