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.

This book provides a unique synthesis of concepts and tools to examine natural resource, socio-economic, legal, policy and institutional issues that are important for managing urban growth into the future. The book will particularly help the reader to understand the current issues and challenges and develop strategies and practices to cope with future pressures of urbanisation and peri-urban land, water and energy use challenges. In particular, the book will help the reader to discover underlying principles for the planning of future cities and peri-urban regions in relation to: (i) Balanced urban development policies and institutions for future cities; (ii) Understanding the effects of land use change, population increase, and water demand on the liveability of cities; (iii) Long-term planning needs and transdisciplinary approaches to ensure the secured future for generations ahead; and (iv) Strategies to adapt the cities and land, water and energy uses for viable and liveable cities. There are growing concerns about water, food security and sustainability with increased urbanisation worldwide. For cities to be liveable and sustainable into the future there is a need to maintain the natural resource base and the ecosystem services in the peri-urban areas surrounding cities. This need is increasing under the looming spectre of global warming and climate change. This book will be of interest to policy makers, urban planners, researchers, post-graduate students in urban planning, environmental and water resources management, and managers in municipal councils.

Despite the importance of nutrient-water interactions, they are often ignored in analysis. After discussing the interrelationships between soil nutrients and water and reviewing methods for determining nutrient balances, this report describes an array of available methods for soil nutrient valuation and provides a discussion of four nutrient valuation studies, which together cover a range of scales, perspectives, and geographic contexts. It also includes case studies from Ghana, Mexico, sub-Saharan Africa, and an examination of possible approaches to valuing soil organic matter and its various functions--an often ignored area in literature.

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.

The book focuses in detail on learning and adapting through partnerships between managers, scientists, and other stakeholders who learn together how to create and maintain sustainable resource systems. As natural areas shrink and fragment, our ability to sustain economic growth and safeguard biological diversity and ecological integrity is increasingly being put to the test. In attempting to meet this unprecedented challenge, adaptive management is becoming a viable alternative for broader application. Adaptive management is an iterative decision-making process which is both operationally and conceptually simple and which incorporates users to acknowledge and account for uncertainty, and sustain an operating environment that promotes its reduction through careful planning, evaluation, and learning until the desired results are achieved. This multifaceted approach requires clearly defined management objectives to guide decisions about what actions to take, and explicit assumptions about expected outcomes to compare against actual outcomes. In this edited book, we address the issue by pursuing a holistic and systematic approach that utilizes natural resources to reap sustainable environmental, economic and social benefits for adaptive management, helping to ensure that relationships between land, water and plants are managed in ways that mimic nature.

The book promotes the study and application of the agro-ecology for developing alternatives to the complex problems of resource depletion, environmental degradation, a narrowing of the agrobiodiversity, consolidation, and industrialization of the food system, climate change, and the loss of farmland. This book covers food systems approaches, and seek experiences in an ecofriendly that are on-farm, participatory, change-oriented, and backed by broad-based methodologies for sustainability analysis and evaluation. The objectives of this book are: (1) to understand the role sustainable agricultural productivity, and its importance to the sustainable soil management, (2) to restore the soil health to transforming agriculture for sustainability, and (3) to understand the matching of management rules in the climatic perspective.
