Drylands cover 41 percent of the Earth's land surface. This publication presents the results of the first global assessment of trees, forests and land use in these lands. The assessment breaks new methodological ground: it relies on the visual interpreation of freely available satellite images, carried out by more than 200 experts in a series of regional workshops. Using a tool called Open Foris ollect Earth, developed by FAO in collaboration with Google, participants gathered and analysed information for mrore than 200 000 sample plots worldwide. For each region, the report summarizes the distribution of forests, other wooded land and other land uses including grasslands, croplands, built-up areas and barren land, across all drylands and by aridity zone. It also estimates tree canopy cover, shrub cover, forest type and presence of trees outside forest. Indicatng that the global drylands contain more than one-quarter of the world's forest area, and that trees are present on 31 percent of the world's dryland area, the report provides a baseline for future monitoring and will support countries in their efforts to identify appropriate investments for the restoration and sustainable management of drylands.

Community-oriented conservation of natural resources and promotion and protection of trees in drylands are examples to deal with climatic adversities. This book provides knowledge on climatic, ecological, social and economic condition of dry areas and lay out approaches and strategies to restore degraded lands. There are 15 chapters and first five deals with physiography of Rajasthan, drylands ecology, problems of land degradation, its economic evaluation and the approaches and strategies of restoration and rehabilitation. Next two chapters describe the problems of sand drift, salinity, water logging and effluent inflicted areas and strategies to control them. Chapters 8-10 deal with seed production, quality planting materials, genetic improvement, propagation and planting techniques. Chapters 11-12 describe methods of rain water harvesting and irrigation, and resources conservation for seed sowing and favouring regeneration and successions. Effective management of pests/diseases in nurseries and plantation, growth and yield prediction equations and models, and people's perception and participation in managing forest resources have been described in last 3 chapters. Purpose of this publication is to strengthen the forest functionaries and readers with wide ranging knowledge on land degradation, desertification and eco-biology of drylands; and methods to restore and rehabilitate degrading forest (lands) to increase forest cover, enhance resilience and people livelihoods and improve environmental conditions. Academician, researchers, forest managers, non-government organizations, extension agents and environmentalists can use it in developing, conserving and managing drylands ecosystems for its long lasting beneficial effects. This book is also useful to policy makers in effective planning of restoring, protecting and conserving dryland's ecological and socioeconomic services.

Tree-based production systems have enormous potential to reduce vulnerability and increase the resilience of households living in dryland regions of Sub-Saharan Africa. Trees are key providers of biomass, which is critical for many livelihood needs. Wood from trees is the leading source of energy in many dryland countries and is an important construction material. Foliage and pods from trees and shrubs are the most important source of feed for camels and goats, which are the dominant livestock species in the more arid parts of the drylands. Trees and shrubs offer enhanced sources of the organic matter needed to improve the structure and raise the fertility of soils used for agriculture. Many parts of trees provide different medicinal products for people. And fruits and vegetable foliage harvested from trees are important seasonal food sources for people living in drylands, and for sale. The benefi ts from trees take on added value when one considers that they are relatively impervious to many of the shocks that affect other production systems, especially livestock keeping and agriculture. Trees, with their deep rooting systems, maintain their standing value and offer some production even in drought years. They are therefore a good buffer against climatic risk and are a critical element in a diversifi cation strategy designed to maintain levels of consumption and income in good times and bad. In addition, their value can be tapped when it is most needed: wood from trees can be harvested throughout the year, and many annual tree products are harvested at times different from the times when annual crops are harvested. Tree-Based Production Systems for Africa’s Drylands identifi es some of the most promising investment opportunities at the level of tree-based systems, species (products), and well-defi ned management practices for accelerating rural economic growth in the drylands.

Leavened with humor and rueful wisdom, Nold's pithy descriptions zero in on each plant's outstanding ornamental characteristics while giving the reader an accurate idea of what to expect from the plant's performance in the garden." "Although Nold addresses himself primarily to western gardeners, anyone with an interest in hardy, drought-tolerant plants will find in these pages an abundance of tempting possibilities with which to experiment."--BOOK JACKET.
