Sustainable intensification (SI) has emerged in recent years as a powerful new conceptualisation of agricultural sustainability and has been widely adopted in policy circles and debates. It is defined as a process or system where yields are increased without adverse environmental impact and without the cultivation of more land. Co-written by Jules Pretty, one of the pioneers of the concept and internationally known and respected authority on sustainable agriculture, this book sets out current thinking and debates around sustainable agriculture and intensification. It recognises that world population is increasing rapidly, so that yields must increase on finite land and other resources to maintain food security. It provides the first widely accessible overview of the concept of SI as an innovative approach to agriculture and as a key element in the transition to a green economy. It presents evidence from around the world to show how various innovations are improving yields, resilience and farm incomes, particularly for ‘resource constrained’ smallholders in developing countries, but also in the developed world. It shows how SI is a fundamental departure from previous models of agricultural intensification. It also highlights the particular role and potential of small-scale farmers and the fundamental importance of social and human capital in designing and spreading effective innovations.

From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. Since 1950, however, the yield per unit of land area for major crops has increased dramatically. Much of the increase in yields was because of increased inputs of energy. Between 1950 and 1985, the farm tractor fleet quadrupled, world irrigated area tripled, and use of fertilizer increased ninefold. Between 1950 and 1985, the total energy used in world agriculture increased 6. 9 times. Irrigation played a particularly important role in the rapid increase in food production between 1950 and 1985. The world's irrigated land in 1950 totaled 94 million hectares but increased to 140 million by 1960, to 198 million by 1970, and to 271 million hectares in 1985. However, the current rate of expansion has slowed to less than 1 % per year. The world population continues to increase and agricultural production by the year 2000 will have to be 50 to 60% greater than in 1980 to meet demands. This continued demand for food and fiber, coupled with the sharp decline in the growth rate of irrigation development, means that much of the additional agricultural production in future years must come from cultivated land that is not irrigated. Agricultural production will be expanded in the arid and semiarid regions because these regions make up vast areas in developing countries where populations are rapidly rising.

Sustainability is extremely important in dryland farming under global climatic change. Technology devised by various agricultural institutions is provided in this book.Variation in environmental factors may influence entire ecological system which may not be ideal for agriculture. Under such global scenario , plant growth is under geopardy. New varieties have to be developed to suit the varied climate or crop strategy in view of crop domain suiting ideal available temperature has to be framed to make dryland farming sustainable .Various agrotechnology needs to be adapted to avoid depletion in productivity. Global climatic change in future may limit the productivity of available varieties. Corporate farming may come to rescue the problem under present scenario. Various agrotechnologies described in this book may help the farmers and planners to overcome the situation in future. Critical problems have been dealt with probable solutions to suit the requirements .Multicropping system , organic farming, , watersheds promotion, reclamation of degraded soils, soil health cards, use of portrals of weather forecast, early harvest on physiological maturity and use of instant remedies timely under unfavourable season shall ease the failure of crop . Long outstanding demand has thus fulfilled with this book.

Drylands cover 41 percent of the earth' s terrestrial surface. The urgency of and international response to climate change have given a new place to drylands in terms both of their vulnerability to predicted climate change impacts and their potential contribution to climate change mitigation. This book aims to apply the new scientific insights on complex dryland systems to practical options for development. A new dryland paradigm is built on the resources and capacities of dryland peoples, on new and emergent economic opportunities, on inward investment, and on the best support that dryland science can offer.

It is known that dryland farming is not remunerative due to several constraints. Location specific technologies have been evolved for yield stabilization in dryland farming and conservation of fragile ecosystem by sustainable use of soil and water resources. Drought and flood situations are experienced some where in the country inspite of pletifull resources of waters unshine hours but poverty among farmers still exists. This is a point of sereous concern. Agrotechniques are alone the answer for low productivity (0.8 t/ha) of 90% rainfed farming. To feed over one billion gallowping population of country, there is a need to increase the productivity to 1.5 t/ha by 2010 AD. This book deals with seed, soil, watersheds, crop, weed and nutrient management use of weather forecast, measure to save crops under abiotic stresses like drought and flooding, selection of crops and variety, reclamation of degraded land, organic recycling, agro-meterological approaches, water requirement, early harvest on physiological maturity, agro-hydro modelling and suitable medicinal and aromatic crops to make dry farming remunerative for welfare of common farmers. This is the first comprehensive book where large number of agro-techniques are incorporated. Chapters are written by eminent scientists of national repute who have devoted their life time to solve probable problems of dryland. Agro-techniques can well be adopted with ease by farmers through extension agencies to avoid bankrupsy. Book includes all relevant aspects of rainfed farming and is therefore a valuable addition in Dryfarming and meets the expectations of all those interested in rainfed farming in the country and abroad. Long outstanding demand has thus fulfilled with this book. The novel approach of editor has made the readers task quick and minimized their efforts by compiling all agro-techniques together at one place for benefit of farmers.

This contributed volume describes management practices based on interdisciplinary and convergence science approaches from different disciplines of agricultural science to enhance the resilience of dryland agriculture. The main focus of this book is to address the current issues and trends along with future prospects and challenges in adopting salient agricultural management practices in drylands globally under a climate-change scenario. Climate change and global warming have profound repercussions on increasing frequency, severity, and duration of droughts and/or floods, which may have implications for future productivity of dryland agriculture, e.g., more water shortages or abundances and high or low runoff rates, diminished crop yields, and reduced water productivity. In past few years, many technological advancements and management strategies have been evolved to tackle the climate-induced risks of dryland agriculture considering interdisciplinary and convergence approaches that integrate knowledge from multi-disciplines. This book is an attempt to bridge the gap in literature by unraveling controversies and characteristics of dryland ecosystems under the changing climate and dealing with detailed procedures of applying the advanced practices adapted to climate change for management of dryland agriculture. This edited book is of interest to ecologists, economists, environmentalists, geologists, horticulturalists, hydrologists, soil scientists, social scientists, natural resource conservationists and policy makers dealing with dryland agriculture. This book offers a broad understanding of dryland agriculture and assists the reader to identify both the current as well as the probable future state of dryland agriculture in a global context.
