Located in a narrow grassland corridor between the semi-desert and a mountain range in Northwest China, the research area Urumqi Region is despite its semi-arid climate in a relatively favourable hydrological situation. The nearby mountains provide water for settlements and agriculture, making human development possible in the first place. Due to the development of agriculture, population and economy during the last sixty years and the increasing water consumption, a demand- and population-driven water scarcity exists today and is expected to aggravate. At the same time, the effects of climate change and land use transformations on the hydrological system and the water availability are uncertain. This study evaluates the recent and future situation by combining a hydrological water balance model for the simulation of the water supply based on scenarios of climate and land use change with a socio-economic model for projecting the future water demand including predicted growth of population and economy.

Sustainable development in the already vulnerable MENA Region faces several challenges, among which is climate change. Though the MENA Region is not a main contributor to climate change, it is predicted that several vital sectors will be negatively impacted, which is a threat to the sustainability of its socio-economic development. Water availability in the MENA Region is expected to be negatively impacted by climate change due to the predicted reduction of rainfall and increased evaporation. In addition, domestic and agricultural demands for freshwater will dramatically increase due to the expected temperature rise, which will enlarge the already existing gap between supply and demand in several MENA countries. It is important to note that the negative impacts on water resources will directly translate to other sectors due to their strong connectivity with the water sector. These sectors are food security, health, ecology, environment, economy and social. Predicted sea level rise due to melting of the poles is expected to result in land use change, which will in turn have severe social and economic consequences. Proper mitigation and adaptation options that take into consideration the multi-dimensional nature of the climate change impacts are imperative to conserve these sectors and to sustain the socio-economic development of the MENA Region. The objective of this book is to provide readers with state-of-the-art knowledge of diverse experiences related to the possible climate change impacts, mitigation and adaptation options in the MENA Region, and to identify and to deliberate upon the research needs and concepts against the background of increasing threats to ecosystems, economy and human health.

Establishing the mechanism of realizing the value of ecological product is an important way to realize land use change, agricultural production transformation and reduce environmental pollution. In recent years, consumers' demand for ecological products has been increasing while the supply is seriously insufficient. The realization of ecological product value faces various bottlenecks, including the realization mechanism of ecological product value, land use variation and the temporal dynamics of land use change, and the driving forces behind land dynamics and their socio-ecological feedbacks. Meanwhile, the relationship between the realization of ecological product value, land use transformation and changes in agricultural production mode are still unclear. In the process of realizing the value of ecological products, how to realize agricultural production and land use transformation, and environmental improvement is also a constant concern to be solved desperately.

This book presents papers from an international conference, held in Bonn, Germany in February 2005, that dealt with integrated water resources management in industrialized and developing countries. The papers detail such emerging concepts as blue and green water, virtual water, the water footprints of nations, multi-agent modeling, linkages between water and biodiversity, and social learning and adaptive management.

Global climate change is expected to have major impacts on water resources and aquatic ecosystems. This prospect presents planners, who are already struggling to meet the demands of growing populations and economies, with new challenges. This volume examines these challenges and the resulting conceptual issues for water planning and project evaluation practices. The book is the first attempt to consider whether and how water resources, planning principles and evaluation criteria should be altered in view of the potential impacts of anthropogenically induced climate change. The principles and procedures that are in use today along with new approaches to nonstructural flood plain management, watershed management, water markets, and wetland banking will serve as the basis for the policies and strategies that deal with climate variability and anticipated change. This collection of papers reviews what water management ideas work, which ones need to be changed, and how planners and managers should begin incorporating aspects of risk and uncertainty into management decisions to deal expertly with climate change.

Describes the water management community¿s needs for climate change info. and tools to support long-term planning. Technical specialists and program managers have worked with their planners, water operators, and environmental compliance managers to identify the information and tools most relevant to their programs. They also have engaged and consulted with other Federal, State, and local agencies and stakeholder groups that have a role in water and water-related resource management to identify complementary priorities and individual perspectives. This report will help focus research and technology efforts to address info. and tools gaps relevant to the water management user community. Charts and tables. This is a print on demand report.

The quantitative assessment of the impact of climate change on water availability and water resources management requires knowledge of climate, hydro(geo)logical and water resources models, and particularly the relationships between each of them. This book brings together world experts on each of these aspects, distilling each complex topic into concise and easy to understand chapters, in which both the uses and limitations of modelling are explored. The book concludes with a set of case studies using real-life examples to illustrate the steps required and the problems that can be faced in assessing the potential impacts of climate change on water resource systems. For students, scientists, engineers and decision-makers alike, this book provides an invaluable and critical look at the information that is provided by climate models, and the ways it is used in modelling water systems. A key focus is the exploration of how uncertainties may accrue at each stage of an impacts assessment, and the reliability of the resulting information. The book is a practical guide to understanding the opportunities and pitfalls in the quantitative assessment of climate change impacts and adaptation in the water resource sector.
