A Guide for Desert and Dryland Restoration is the first comprehensive book focused on restoring arid regions, and clearly demonstrates that arid lands can be successfully rehabilitated. In addition to restorationists, the book will be an invaluable resource for anyone working in arid lands, including farmers, ranchers, gardeners, landscapers, outdoor recreation professionals, and activists.

"Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally-leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography" "This book brings together the worldwide experience of internationally leading experts to fill this gap in the scientific and technical literature.

This book discusses ways of increasing production/unit area by making full use of the soil and water under the harsh climatic conditions of semiarid areas. This leads to improved sustainability, increased availability of fresh produce, which is vital for human health and higher incomes for small and marginal farmers. Arid and semiarid areas account for almost 70 per cent of the total cropped area of India. In these areas physical constraints like low and erratic rainfall, high temperature, high wind velocity, low fertility, poor soil structure, salinity of soil and ground water all limit reliable crop production. In the absence of any type of aggregation, the soils are highly erodible, lack structure and have a very coarse in texture with low water holding capacity. Intensive agricultural practices, increasing population pressure, climatic changes, environmental pollution, loss of biodiversity, soil erosion, salinization and water depletion are all threatening the sustainability of agriculture. In view of the mounting demand for food, it is vital to link enhanced food production with nutritional security, conservation of natural resources, increasing farmers’ incomes, employment generation through agricultural diversification. Horticulture, particularly of fruit trees, can play a major role in solving the problem of nutrition, as fruits are rich source of vitamins and minerals and have antioxidant properties. Fruit trees, which are mostly deciduous, add leaf litter to the soil, and this ultimately helps to improve the condition of the soil. In addition, fruit trees are known to reduce soil erosion and reduce run off. The trees also play a major role in purifying the environment as they are the known carbon sequesters. Fruit-tree cultivation is a profitable preposition. There is no scope to increase the land surface; all increase in productivity therefore has to be from the available land. This means introducing cropping systems that can meet the basic food, fodder and fuel requirement of farming families.
