Thar Desert in India is one of the most well-investigated and densely populated regions amongst the world arid zones. A blend of crop and animal husbandries, conservative land use practices, coping mechanisms to minimize adverse effect of drought and a frugal lifestyle have been the characteristic features of its dwellers. Recent increase in biotic pressure has interacted with the fragile environment to create fearsome environmental problems. Governmental responses were prompt in form creating a strong research infrastructure for multi-disciplinary and multi-location research and demonstration on the one hand and in huge investment in irrigation from internally and externally sourced water, desertification control program and an accelerated socio-economic and infrastructure development, softening content of drought and strengthening of livelihoods on the other. Unlike several publications on the Thar, the current effort attempts a comprehensive, pragmatic and off-beat analysis of various developments and goes further to show how the situation today is a blend of both resource degradation and economic development. Recent studies have helped rebuild the past climate history that shows that the climate has been fluctuating during the geological history but reports suggest also that current anthropogenic global warming makes the desert more vulnerable in near future. An attempt has been made also to peep into the future of the Thar.

Drought is a natural hazard characterized by lower than expected or lower than normal rainfall having slow but widespread impact. This book focus on drought management and mitigation in agriculture and allied sectors. The chapters cover Basic concepts, assessment, monitoring, forecasting, early warning, vulnerability and adaptation to drought and mitigation and management strategies. Management of different land use systems under drought and finally socio economic impact and livelihood issues of drought are also focussed. It would be useful to a wide range of stakeholders, i.e. planners, researchers, students and interested public. This will also serve as text book as well as supplementary reading for courses in agronomy, ecology, geography and agro meteorology besides administration and disaster management units.

Over the years, economic considerations have overtaken the sustainability issue. Low and erratic rainfall, frequent droughts, the increasing costs of cultivation, lower compensation of labour and inputs have made farming in the arid regions a challenging enterprise. Employment opportunities in sectors other than agriculture have enticed many to cross the floor. The largest segment of the farming community, however, is constrained to make a living from farm related activities. With the opening of markets for international trade in farm commodities, the competition has toughened for the resource-constrained farmers of the arid regions of the country. On the other hand, useful technologies have been generated by researchers on many alternative systems, which could be adopted. In this scenario, the farmers could benefit greatly by inducing diversification in the farming systems and by strengthening the traditional systems. With this backdrop, a National Symposium on Livelihood Security and Diversified Farming Systems in Arid Region was organized by the Arid Zone Research Association of India at the Central Arid Zone Research Institute, Jodhpur, from January 14-16, 2006. Selected papers presented at the symposium and invited articles have been included in this compendium and are grouped in sections on Diversification, Strengthening the Traditional Farming Systems, Enhancing Resource Use Efficiency, Livestock-based Farming Systems, Value Addition, Socio-economic Issues and Transfer of Technology. Currently, food, water and energy crises are of global concern. The challenge ahead is to strike a balance between basic needs of a large population and to maintain the pace of development. Diversification of farming systems may contribute towards achieving this goal to some extent. It is hoped that the book will provide options for diversification of the existing farming systems and benefit there from.

Biotechnology is an emerging field of science and as such the government of India is laying a large and exclusive impetus on it. Plant tissue culture is the basic and the most important aspect of Biotechnology. All the molecular biological and biotechnological findings can only be realized in material by the plant tissue culture. Therefore, plant tissue culture has been introduced as a compulsory course in the Undergraduate and Postgraduate syllabi of all the Agricultural Universities, ICAR institutes and other plant science related educational organizations. This book has been designed to benefit the students, the research scholars and the scientists for developing a level of self-confidence to conduct the experiments independently and can acquire the practical skills along with the basic know-how about the techniques being used. Each chapter is devoted to a separate aspect of plant tissue culture and the chapters are arranged in the order of increasing technical complexity. The opening chapters present a brief historical survey of the field of plant tissue culture, a background in sterilization techniques. Various components of the nutrient medium have been dealt in greater detail. The text deals with the experimental details of each and every technique. The protocols have been simplified legibly to include details and notes that we hope will help the user avoid unnecessary errors and confusion. All the applications of plant tissue culture have been very well discussed and the techniques associated with them described in detail. This being a complete book on Plant tissue culture will solve all types of problem of the users who will not have to use other resource books for the same purpose.

Vertebrate pests cause considerable damage to environment, agriculture and biodiversity apart from transmitting diseases. The problem is more pronounced in tropical Asia and Africa with non-human primates, elephants, several species of ungulates, rodents, frugivorous and grainivorous birds causing agricultural losses. In Europe and America the damage is due to carnivore predation on livestock, bird damage in cereal crops and rodent problem in urban and agricultural situations. Although there are several excellent books on rodent pest management both in India and at global level, there is a conspicuous lacuna of published books on vertebrate pest management. Even the few publications on the subject mostly deal with birds, rodents, bears, rabbits, foxes, etc because they are written by Americans or Britishers. Because their emphasis is on the problem prevalent in their countries and evaluation of management options available to them. In contrast the problem in tropics especially in India is unique. Rodents of course, are the most destructive. But what rodents do over twelve months of year is matched by a few nights of devastating crop raids by elephants or week long foraging by monkeys. Sporadic and localized damage is inflicted by several species of birds, bats, wild boar, blue bull, bears, hares, peacock etc. The damage is sometimes so high, it is impossible for a subsistence farmer to accept stoically the loss of his entire food source over a couple of days and nights. However, his options are limited in view of conservations and protection status enjoyed by some of these animals. The problem is compounded by religious sentiments associated with a few of them. This book is an attempt to find an acceptable solution to the problem of crop losses of these less studied but economically important groups of vertebrate pests. Sincere efforts have gone into formulation of recommendations keeping in mind the biological needs of vertebrate pests, their conservation status and suffering of the poor farmer. Many a time the sympathies deservedly go to the speechless marauders of crops as it is man who has shrunk, degraded and destroyed their habitat, deprived them of their natural source of food. There are no choices for vertebrate pests but raid the crops in their range but we, humans have several to survive. The book is an attempt to understand this dilemma.

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 volume contents aspects as crops i.e. Clusterbean, Mothbean, Cowpea, Horsegram, Mungbean, Rice bean, Indian bean, Winged bean and other minor pulses grown in arid and semi-arid regions.
