The book is a comprehensive manual of practice for execution of afforestation and tree planting programmes in arid and semi-arid tropics. It includes a compact running account of the technology of afforestation and the relevant principles and practices in management of afforestation projects. It provides a wide range of structured information and a number of model designs which can be gainfully put to use by the field level supervisors as also by the managers concerned with planning and control of such projects. Written by a practising specialist, the book is invaluable for anyone concerned with the practice of afforestation and tree planting, be he a tree hobbyist or a school teacher, a professional forester or a senior policy maker in government, an industrialist or a philanthropist, an environmental activist or a member of a community service organization.

Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.

Forests and Forest Plants is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Forests are an essential part of Earth's life support systems. Forest resources are essential for humankind. They provide both vital goods and services. They provide food, fuel, shelter, soil and water protection, and filter the air we breathe. This publication on Forest and Forest Plants provides the user with such information as to create an awareness of the value of our forestlands and the products and environmental services they provide. The three volumes on Forests and Forest Plants are organized starting with first the necessity of : the World's Forest Resources – including classification and distribution of forest, urban forestry and agroforestry; Important Tree Species including trees in reclamation and arid zone forestry; Forests and Forest Products including wood and non word products; the Role of Forests in the Biosphere – preserving biological diversity, functions in the hydrological cycle, etc.; and Conservation and Breeding of Forest Trees – what is being done to improve our forest resources - silviculture, tree nurseries, and forest protection. The theme Forest and Forest Plants has led to the conclusion that there are substantial difficulties in matching environmental concerns and sustainability with an ever-increasing world population. Thus there is a tension between maximizing for food, wood and production on the one hand and implementing sustainable development and environmental protection on the other. These three volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

This book contains a selection of papers presented at the first International Symposium on Windbreak Technology, summarising the available worldwide literature on windbreaks and the response, both positive and negative, to wind protection. State-of-the-art information is presented on general design criteria, and principles of planting and establishment for a wide range of conditions and objectives. It provides descriptive information of tree and shrub species for arid, semi-arid, temperate and tropical areas, and their use in windbreaks.
