Book Description
In many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined. This report synthesizes findings from multidisciplinary studies conducted into sustainable wetland agriculture by IWMI and partners in Africa and Asia. It highlights the value of wetland agriculture for poverty reduction as well as the need for more systematic planning that takes into account trade-offs in the multiple services that wetlands provide.

Book Description
In this book the authors argue for a paradigm shift in the way African wetlands are considered. Current policies and wetland management are too frequently underpinned by a perspective that views agriculture simply as a threat and disregards its important contribution to livelihoods. In rural areas where people are entrenched in poverty, wetlands (in particular wetland agriculture) have a critical role to play in supporting and developing peoples' livelihoods. Furthermore, as populations rise and climate change takes grip they will be increasingly important. The authors argue that an approach to wetland management that is much more people focused is required. That is an approach that instead of being concerned primarily with environmental outcomes is centred on livelihood outcomes supported by the sustainable use of natural wetland resources. The authors stress the need for Integrated Water Resource Management and landscape approaches to ensure sustainable use of wetlands throughout a river catchment and the need for wetland management interventions to engage with a wide range of stakeholders. They also assess the feasibility of creating incentives and value in wetlands to support sustainable use. Drawing on nine empirical case studies, this book highlights the different ways in which sustainable use of wetlands has been sought, each case focusing on specific issues about wetlands, agriculture and livelihoods.

Book Description
In recent years, development policy has responded to an increasing concern about natural resource degradation by setting up innovative payment for environmental services (PES) programs in developing countries. PES programs use market and institutional incentives in order to meet both environmental and poverty alleviation objectives. However, their optimal design, implications for the rural poor, and how these initiatives integrate into international treaties on global warming and biodiversity loss are still being discussed. This book addresses these issues by scrutinizing analytical tools, providing policy insights and stimulating debate on linkages between poverty alleviation and environmental protection. In particular, it turns attention towards the role of environmental services in agricultural landscapes as they provide a living for many poor in developing countries. It serves as a valuable reference for academics and students in various disciplines, as well as for policy makers and advisors. This book is a co-publication between Springer and the Food and Agriculture Organization of the United Nations.

Book Description
The study used a combination of landscape-scale synoptic surveys (catchment, reaches) and mesocosm surveys (experimental plots) to assess the impacts of conversion of natural valley-bottom wetlands to farming land on the water quality and retention of sediment and nutrients. The results showed that temperature, pH, electrical conductivity and dissolved oxygen concentration decreased, and total suspended solids (TSS) increased with storm water increase. Nitrogen (TN) and phosphorus (TP) accumulated in the catchment during the dry season and washed into the water courses during the early stages of the higher flows, with subsequent lower concentrations at the end of the rains due to dilution. Large proportions of the annual loads of TSS, TP and TN (93%, 60% and 67%, respectively) were transported during rainfall events that occurred in 115 days. Fishponds acted as temporal traps of TSS, TN and TP at the early stages of farming, and were a source of and TN and TP at the end of the farming period, in contrast to rice farming that generated sediments and nutrients early in the farming period and trapped them at the end of the farming season. Wetlands mostly acted as sinks but sometimes as a source of sediment and nutrients.

Book Description
All statistical evidence confirms that agriculture is the key sector for water management, now and in the next decades. Nevertheless, the rural water development sector fails at present to get priority, compared to other competing sectors, in international fora. Strong and new arguments are needed to bring rural water back "on line." Agriculture policies and investments will need to become more strategic. They will have to unlock the potential of agricultural water management practices to raise productivity, spread equitable access to water, and conserve the natural productivity of water resources base.

Book Description
Under FAO initiative on eco-friendly water management for sustainable wetland agriculture, the Asian Institute of Technology (AIT), as the service provider, prepared the Study Report on Wetland Agriculture and Water Management in Mekong Region study report on wetland agriculture and water management in the Mekong Region for further program formulation. The overall objective is to review the current water management in relation to agriculture and identify the good practices and experiences of water management as a win-win solution for agriculture production and wetland conservation and recommend program formulation on eco-friendly water management for sustainable wetland agriculture. The expected outcome of the overall initiative is sustainable use of wetland to stress both productive and ecological functions of agriculture. The outputs aim to provide the solution as a win-win strategy for wetland and agriculture through eco-friendly water management, which will contribute to the ecological health, function and integrity of the Mekong Wetland Agriculture Ecosystem. Country consultation workshops were conducted for Cambodia, Laos, Thailand, and Vietnam to increase awareness on the issues of sustainable wetland management, and identify the threats, gaps and needs, priorities, and way forward towards sustainable use of wetlands in the Mekong Region.

Book Description
This paper reports on a form of multi-criteria analysis that provides a formal approach for evaluating the suitability of a wetland for specific agricultural uses, and ensures that explicit consideration is given to the possible consequences of such utilization. The method is based on a hybrid of ideas taken from concepts and methodologies related to: environmental flow assessments, land suitability classification and the hazard evaluation procedures used in the design of dams. The approach, which elaborates the idea of working wetlands, is generic, though the examples presented are for case studies from southern Africa.
