Agroforestry, the word coined in early seventies, has made its place in all the developed and the developing countries of the world and is now recognized as an important approach to ensuring food security and rebuilding resilient rural environments. India has been an all-time leader in agroforestry. The South and Southeast Asia region comprising India is often described as the cradle of agroforestry. Almost all forms of agroforestry systems exist across India in ecozones ranging from humid tropical lowlands to high-altitude and temperate biomes, and perhumid rainforest zones to parched drylands. The country ranks foremost among the community of nations not only in terms of this enormous diversity and long tradition of the practice of agroforestry, but also in fostering scientific developments in the subject. Agroforestry applies to private agricultural and forest lands and communities that also include highly erodible, flood-prone, economically marginal and environmentally sensitive lands. The typical situation is agricultural, where trees are added to create desired benefits. Agroforestry allows for the diversification of farm activities and makes better use of environmental resources. Owing to an increase in the population of human and cattle, there is increasing demand of food as well as fodder, particularly in developing countries like India. So far, there is no policy that deals with specifics in agroforestry in India. But, the Indian Council of Agricultural Research has been discussing on the scope of having a National Agroforestry Policy in appropriate platforms. However, evolving a policy requires good and reliable datasets from different corners of the country on the subject matter. This synthesis volume containing 13 chapters is an attempt to collate available information in a classified manner into different system ecologies, problems and solutions, and converging them into a policy support.

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.

Over the years, the interactions between land, ocean, biosphere and atmosphere have increased, mainly due to population growth and anthropogenic activities, which have impacted the climate and weather conditions at local, regional and global scales. Thus, natural hazards related to climate changes have significantly impacted human life and health on different spatio-temporal scales and with socioeconomic bearings. To monitor and analyze natural hazards, satellite data have been widely used in recent years by many developed and developing countries. In an effort to better understand and characterize the various underlying processes influencing natural hazards, and to carry out related impact assessments, Natural Hazards: Earthquakes, Volcanoes, and Landslides, presents a synthesis of what leading scientists and other professionals know about the impacts and the challenges when coping with climate change. Combining reviews of theories and methods with analysis of case studies, the book gives readers research information and analyses on satellite geophysical data, radar imaging and integrated approaches. It focuses also on dust storms, coastal subsidence and remote sensing mapping. Some case studies explore the roles of remote sensing related to landslides and volcanoes. Overall, improved understanding of the processes leading to these hazardous events will help scientists predict their occurrence. Features Provides information on the physics and physical processes of natural hazards, their monitoring and the mapping of damages associated with these hazards Explains how natural hazards are strongly associated with coupling between land–ocean–atmosphere Includes a comprehensive overview of the role of remote sensing in natural hazards worldwide Examines risk assessment in urban areas through numerical modelling and geoinformation technologies Demonstrates how data analysis can be used to aid in prediction and management of natural hazards

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.
