Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.

This volume provides state-of-the-art information on soil-water interactions in wastewater systems, characterization of wastewater, modes of treatment, safety of wastewater use, water conservation technologies involved in recycling of sewage in fish culture, biogeochemical cycling bacteria and nutrient dynamics, ecosystem resilient driven wastewater reclamation, bioremediation, aquaponics, ecological integrity, culture practices of fish farming, microbial food web phenomena, fish diseases, environmental economics of wastewater, environmental risk assessment, environmental law and regulations. Given its breadth of coverage, the book will be useful to researchers, teachers, students, administrators, planners, farmers and entrepreneurs interested in the profitable use of wastewater in the wastes-into-wealth framework of for the benefit of humanity, and in achieving the targets for sanitation and safe wastewater reuse by 2030, specified in the United Nations’ Sustainable Development Goals. Concerns are growing about the quality and quantity of fresh water, as severe crises are expected in the near future. Climate change has further worsened the strain on inland water resources, with its major impacts on ecosystems and human life. It is most urgent to protect and conserve inland water resources to maintain vital ecosystem functions. Despite the immense nutrient potentials of wastewater in terms of phosphorus, nitrogen and potassium and increasingly high rates of urbanization-based wastewater generation, wastewater has traditionally been overlooked as a resource. This produces a threefold loss – environmental degradation, monetary losses from fertilizers, and water. As a result, municipal wastewater offers a win-win strategy for water conservation and environmental protection, while also turning waste into wealth in the form of fish biomass and allied cash crops. Wastewater-fed aquaculture refers to a unique, integrated biosystem in which the wastes generated by the first system are used by the next subsystem. In wastewater-fed aquaculture biosystems, the organic wastes are recycled into fish biomass mediated through a complex microbial/autotrophic/heterotrophic food web mechanism.

Strategic Perspectives in Solid Waste and Wastewater Management explores conventional and advanced biotechnologies for waste management, including socio-economic aspects, techno-economic feasibility, models and modeling tools, and a detailed life-cycle assessment approach in solid waste (SW) and wastewater (WW). These innovative technologies are highly applicable to current real-world situations. The enormous increase in the quantum and diversity of SW and WW - including waste materials generated due to human activity and their potentially harmful effects on the environment and public health - have led to increasing awareness about an urgent need to adopt novel technologies for appropriate management of both SW and WW. While there is an obvious need to minimize the generation of wastes and to reuse and recycle them, the technologies for managing such wastes can play a vital role in mitigating problems. Besides recovery of substantial energy, these technologies can lead to a considerable reduction in the overall waste quantities requiring final disposal, which can be better managed for safe disposal in a controlled manner while meeting pollution control standards. Outlines appropriate technologies for solid waste and wastewater management systems and their applications Presents and evaluates the Best Available Technology (BAT) and includes global case studies Provides methods for evaluating the way to use appropriate technological systems to develop the best technically and economically feasible projects worldwide Offers an excellent resource for university students to use for their research and dissertations

More than 1 million hectares of urban land in India could be irrigated for crops if wastewater was made safe for use. Lack of systematic data collection by municipalities makes it difficult to accurately assess the wastewater generation or estimate the total amount of urban area under wastewater irrigation, so the potential of urban and peri-urban farming could be even greater. This study attempted to analyze the current status of wastewater generation, its uses and livelihood benefits especially in agriculture, based on national data and case studies from Ahmedabad, New Delhi, Hyderabad, Kanpur and Kolkata.

Focusing on mixed crop-livestock farming systems of sub-Saharan Africa, this review brings together the available knowledge in the various components of the livestock and water sectors. Through an analysis of livestock-water interactions, promising strategies and interventions to improve Livestock Water Productivity are proposed. In the biophysical domain, the numerous interventions relate to feed, water and animal management. These are interlinked with interventions in the socio-political-economic domain. The paper identifies critical research and development gaps in terms of methodologies for quantifying water productivity and integrating different scales, and also in terms of institutions and policies.

In Burkina Faso, at least 1,700 small reservoirs have been constructed, most of them during the last 30 years. Numerous and scattered, these beneficial multipurpose systems combine productive with domestic water uses. However, their environmental and health impacts remain insufficiently documented. This report combines data from different sources into syntheses and national maps, with a focus on water-related diseases. The mitigation of negative impacts requires an integrated approach to specifically identify the enhancing and limiting factors that influence environmental impacts and the transmission of diseases around reservoirs. Public awareness campaigns need to accompany the promotion of preventive and curative measures and the development of alternative water sources for domestic supply.

The Karkheh River Basin is the third largest basin in Iran after Karoon and Dez, and occupies a strategic position on the western boundary of the country. The basin has seen remarkable ancient feats of engineering, and has a long history of wheat and barley production, complemented by horticulture. With the growth of the modern nation-state of Iran, water development has progressed steadily in tandem with rising populations and urbanization. The report aims to understand the historical setting and present situation of water development and allocation, in relation to rural development and agrarian policy. It provides the contextual backdrop for further research on the management of water to improve livelihoods in the basin through integrated and sustainable management of land and water resources. It provides further information on the changes in surface flows out of the component subbasins and looks at the development, use and consequences of groundwater abstraction.

The impact of climate change (CC) on water resources is likely to affect agricultural systems and food security. This is especially true for Nepal, a least developed country, where a high percentage of the population is dependent on agriculture for its livelihoods. It is thus crucial for Nepal’s leaders and resource managers to draft and begin implementing national adaptation plans. This working paper aims to create a more comprehensive understanding of how the impacts of CC will be realized at different scales in Nepal, from household livelihoods to national food security, and the many institutions governing the ultimate adaptation process.
