Описание: Arid and semi-arid regions can be defined as environments in which water is the limit- ing factor for bio-systems. Meeting the first demand, namely, supplying water to the agricultural communities and urban centers, involves, in many instances, the over-exploitation and misuse of nat- ural water resources.

Автор: XiuJun Wang; Zhitong Yu; Jiaping Wang; Juan Zhang Название: Carbon Cycle in the Changing Arid Land of China ISBN: 9811070210 ISBN-13(EAN): 9789811070211 Издательство: Springer Рейтинг: Цена: 102480.00 T Наличие на складе: Есть у поставщика Поставка под заказ. Описание: This book integrates the analyses of organic carbon and carbonate accumulation in soil and lake sediment in a typical arid region of China that has experienced significant climate and land-use changes.It demonstrates that carbonate accumulation greatly exceeds organic carbon in both soil and sediment. It also shows that intensive cropping with sound land management in the arid land not only increases soil organic carbon stock, but also enhances accumulation of soil carbonate, particularly in subsoils. Carbon accumulation in the lake sediment increased between 1950 and 2000, after which it declined, and the authors explore how human activity and climate change may have caused the changes in carbon burial in the lake sediment.This book is of interest to researchers in a number of fields such as soil science, limnology and global change, as well as to the policy-makers.

This book introduces state-of-the-art approaches, methods and research, focusing on smart management of rainwater. In addition, it provides an overview of projects from across the world, illustrating how rainwater-smart management has been implemented in drylands. Focusing on the scientific perspective it demonstrates how rural dryland agriculture can be improved. It also documents the wealth of rainwater-smart know-how available today, and replicates and transfers results to other countries and regions, to encourage cross-sector interactions among various stakeholders, such as practitioners from governmental and public organisations, policy- and decision-makers, and teaching staff from academic scientific institutions.
The contributors showcase vital lessons learned from research, field projects and best-practice examples. They address the integrated use of rainwater harvesting management with landscape restoration practices and water-, and climate-smart agriculture for food security and poverty alleviation in arid and semi-arid areas. Original research, combined with the contributors’ synthetic approach, lays a foundation for new concepts and ideas. Through case studies and research reports, the book discusses all the relevant issues necessary for the comprehensive analysis and successful implementation of the technologies in rainwater management. Highlighting the working principles and technical recommendations with regard to cost-efficient rainwater-smart solutions, it is of interest to practitioners. It is also a valuable resource for academic specialists, professionals and students, since many development agencies are funding rainwater harvesting for irrigation purposes.

Описание: This book discusses the complexity of the interacting abiotic and biotic environment of wetlands across different spatial and temporal scales. It reveals how management based on poor knowledge causes more damage than repair.
Water demand in southern Africa continues to rise, as urban areas expand and as agricultural water demand rises to meet the millennium development food security goals. Water resource availability in the northern Limpopo Basin has declined over the last 30 years, and will decline further under climate change. In this study, water resources modelling is used to quantify the effect of water resources strategies and climatic conditions on water resources availability. This is coupled with water balance modelling to evaluate the potential of alluvial aquifers, which form the beds of sand rivers.
The greatest benefit for the least impact comes from strategies providing for better land and soil/water management, such as changing from maize to small grains, production of livestock fodder and conservation agriculture. Small dams are a key resource to rural communities, and change to Multiple Use Systems through abstraction of water for irrigation has clear benefits locally. There is also great potential for the exploitation of alluvial aquifers for water supply. Better management of existing large dams, together with conjunctive use of alluvial groundwater and several reservoirs could increase productive use of water and significantly improve livelihoods without the construction of new reservoirs.
