Book Description
Dryland mountains are of great strategic value to regional and global development. They provide up to 90% of the freshwater supply to surrounding dry lowlands with more than a quarter of the world's biodiversity hotspots found in drylands mountains. Yet these mountains regions are under increasing threat from climate change and unsustainable forms of land use, including mining and tourism. This publication presents the socio economy and environment of dryland mountains, the current threats they face, and good practice in sustainable development. It concludes with key messages for policy and decision makers.

Book Description
Many dryland regions contain archaeological remains which suggest that there must have been intensive phases of settlement in what now seem to be dry and degraded environments. This book discusses successes and failures of past land use and settlement in drylands, and contributes to wider debates about desertification and the sustainability of dryland settlement.

Book Description
More than 200 million people living in dryland regions of Sub-Saharan Africa make their living from agriculture. Most are exposed to weather shocks, especially drought, that can decimate their incomes, destroy their assets, and plunge them into a poverty trap from which it is diffi cult to emerge. Their lack of resilience in the face of these shocks can be attributed in large part to the poor performance of agriculture on which their livelihood depends. Opportunities exist to improve the fortunes of farming households in the drylands. Improved farming technologies that can increase and stabilize the production of millet, sorghum, maize, and other leading staples are available. Irrigation is technically and economically feasible in some areas and offers additional opportunities to increase and stabilize crop production, especially small-scale irrigation, which tends to be more affordable and easier to manage. Yet many of these opportunities have not been exploited on a large scale, for reasons that include lack of farmer knowledge, nonavailability of inputs, unfavorable price incentives, high levels of production risk, and high cost. Future production growth in drylands agriculture is expected to come mainly from raising yields and increasing the number of crop rotations on land that is already being cultivated (intensifi cation), rather than from bringing new land into cultivation (extensifi cation). Controlling for rainfall, average yields in rainfed cropping systems in Sub-Saharan Africa are still much lower than yields in rainfed cropping systems in other regions, suggesting that there is considerable scope to intensify production in these systems. Furthermore, unlike in other regions, production of low-value cereals under irrigation is generally not economic in Sub-Saharan Africa unless the cereals can be grown in rotation with one or more high-value cash crops. The long-run strategy for drylands agriculture, therefore, must be to promote production of staples in rainfed systems and production of high-value cereals (for example, rice), horticultural cops, and industrial crops in irrigated systems. Based on a detailed review of currently available technologies, Improved Crop Productivity for Africa’s Drylands argues that improving the productivity and stability of agriculture in the drylands has the potential to make a signifi cant contribution to reducing vulnerability and increasing resilience. At the same time, it is important to keep in mind that in an environment characterized by limited agro-climatic potential and subject to repeated shocks, farming on small land holdings may not generate suffi cient income to bring people out of poverty.

Book Description
A richly illustrated atlas of the world’s deserts and drylands, their ecosystems, and their environments Deserts and drylands account for more than 40 percent of land on our planet. Characterized by a lack of water and extreme temperatures, they are the result of atmospheric stability, large landmass characteristics, rain shadows, and cold ocean currents. They appear harsh and hostile, but deserts and drylands are also exceptionally beautiful environments. Desert ecosystems often teem with diverse forms of life that exhibit astonishing ingenuity in the face of such forbidding conditions. The World Atlas of Deserts and Drylands takes readers on a guided tour of some of the most awe-inspiring desert environments on Earth, explaining their environmental and ecological dynamics and describing the techniques used to categorize and map them. From the ever-expanding Gobi of Mongolia and China to the ancient Namib of coastal Africa, this is the ultimate reference book for deserts. Features a wealth of color photos, maps, and infographics Describes the resilient and complex biodiversity of the world’s desert and dryland terrains Covers subtropical deserts, continental deserts, rain shadow deserts, and ocean margin deserts Addresses the challenges posed by global warming and human activity, and discusses solutions and opportunities Written by a team of leading experts

Book Description
Ecohydrology emerges as a new field of research aiming at furthering our understanding of the earth system through the study of the interactions between the water cycle and vegetation. By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently spread in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the drylands around the world. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters collected in this book have been contributed by authors with different expertise, who work in several arid areas around the World. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.
