The world is facing severe and growing challenges in maintaining water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these challenges facing water resources management; and modeling at this scale can provide essential information for policy makers in their decisions on allocation of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

The study was on the performance of the decision support system for agrotechnology transfer (DSSAT) and the soil water atmosphere plant (SWAP) under an acid sulphate soil. The comparison of these models was done as a prerequisite to the selection of an appropriate model, which is capable of simulating water management scenarios, water balance and crop growth, to be coupled with an adaptive optimization algorithm that can be used to explore water management options

Because of a growing and more affluent population, demand for agricultural products will increase rapidly over the coming decades, with serious implications for agricultural water demand. Symptoms of water scarcity are increasingly apparent, threatening ecosystem services and the sustainability of food production. Improved water productivity will reduce the additional water requirements in agriculture. However, there is a tradeoff between the quantity of water used in agriculture and the quality of return flow. Where yields are low due to limited nitrogen (N) and water supply, water productivity can be enhanced through higher fertilizer applications and improved water management. This limits the amount of additional water needed for increased food demand, thus leaving more water for environmental requirements. But it also increases the amount of nitrate (NO3–N) leaching, thus adversely affecting the water quality of return flows. This paper quantifies the tradeoff between enhanced water productivity and NO3–N leaching and shows the importance of the right management of water and N applications. Using the Decision Support System for Agro-technology Transfer (DSSAT) crop model, several scenarios combining different water and N application regimes are examined for maize (Zea mays L.) in Gainesville, FL, USA. Without adequate water, nitrogen use efficiency (NUE) remains low, resulting in substantial NO3–N leaching. Too much water leads to excessive NO3–N leaching and lower water productivity. The lack of N is a cause of low water productivity but too much of it leads to lower NUE and higher losses. The paper concludes that increased NO3–N leaching is an inevitable by-product of increased water productivity, but its adverse impacts can greatly be reduced by better management of water and N application. The paper briefly shows that leaching can be reduced and water productivity increased by split application of N-fertilizer. This implies that improved water and nutrient management at field- and scheme-level is a prerequisite to limit adverse impacts of agriculture on ecosystems, now and especially in the future.

A framework of climate change (CC) analysis is developed using the Decision Support Framework models of the Mekong River Commission (SWAT hydrological, IQQM basin simulation and hydrodynamic iSIS models) to analyze impacts of CC and water resources development on Mekong flow regime. This analysis is based on six model run scenarios defined as combinations of a development scenario, either baseline or 20-year plan and a climate dataset, either observed or from regional downscaling model simulating the past in 1985-2000 or projecting the future climate in 2010-2050. The projected climate shows a slight increase in precipitation throughout the Mekong basin except in the delta. Temperature is projected to increase by 0.023°C/year. During the high-flow season, impacts of CC and development are in contrasting directions. The development brings a decrease of about -8 to -17% of river flow but CC increases +2 to +11%. The combined effect causes changes in discharge from +3% to -13% depending on CC scenarios and location of stations. In the low-flow season, both CC and development will increase river flow, with +30 to +60% due to development and +18 to +30% due to CC. The combined effect is up to +40 to +76%. While development reduces the flooded area, CC will make it larger in a wet year. Salinity intrusion area in the delta could be larger in a dry year under CC but development can reduce the affected area. The analysis shows that adaption strategies are needed to achieve the development objectives under CC conditions.

There is continuing debate about the role of water productivity and the potential to increase it in response to significantly increased water demand to meet the future needs for food—estimated to be roughly double that of today by 2050. The debate centers round the relative potential benefits of enhancing rainfed agriculture, improving irrigation and expanding areas of both. All expansion and intensification options will require significantly more water to be used, often in places where the ecosystem impacts of agriculture are already severe. Improvement in water productivity can result from improving the provision and management of the other factor inputs of crop production. There is considerable debate on the ability of other inputs—typically nitrogen—to substitute for water. This paper describes a set of simulations undertaken with well calibrated maize (Zea mays L.) crop model in Decision Support System for Agro-technology Transfer (DSSAT). The simulations investigate the response to nitrogen under rainfed conditions in Florida, and show that neither the transpiration ratio nor the harvest index are constant in practice, and that fertilizer use can enhance water productivity, even in quite high yield conditions and that the transpiration ratio can be increased by N fertilizer application at low levels of crop water use.

The report aims to provide critical input to the Mekong River Commission’s (MRC) regional Climate Change and Adaptation Initiative (CCAI) which was launched shortly after the formulation of this project. The CCAI is a collaborative regional initiative designed to address the shared climate change adaptation challenges of LMB countries in response to the potential effects of climate change on the socio-economic characteristics and natural resources of the LMB region. MRC has identified need for a more informed understanding of the potential impacts from climate change. To contribute to this aim, the purpose of this report is: 1. To present the framework of climate change analysis and its application to the Basin Development Plan (BDP) Scenarios; 2. To present the results from the application of the Decision Support Framework (DSF) models of the Mekong River Commission (MRC) in order to analyse the impacts of climate change and selected BDP Scenarios on flow regimes; 3. To present climate change impacts on floods and fisheries in the LMB; 4. To present the impact of climate change on the productivity of major crops grown in the basin and their consequences on the overall food security of the basin considering future population growth. 5. To present the results of applying simple adaptation strategies related to agriculture and food security; and 6. To determine further studies necessary to identify suitable adaptation strategies for dealing with such impacts.

This important collection reprints the most significant papers and case studies on the prevention and resolution of conflict over water resources. It focuses in particular on the human dynamics that are involved when conflicts over water resources impact on different interest groups, economic sectors and legal or political boundaries. It addresses key issues which arise at both the local and the international level, including amongst others: How do people interact in these situations of conflict? What methods do they use to find a compromise? What institutions do they create - either jointly or unilaterally - to help overcome problems in the future?
This interdisciplinary collection will be essential reading for professional water practitioners throughout the world, including engineers, economists, geographers, geologists, and political scientists concerned with water disputes and conflict resolution. It will make a significant contribution to the study of water as an essential theme in the increasingly important topic of environmental security.
