*First title in a major new series *Addresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental security *Draws from scientists having a multitude of disciplines to approach this important problem In a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.

Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income. Presenting recent research findings on salt stress, water stress and stress-adapted plants, this book offers insights into new strategies for increasing the efficiency of crops under stressful environments. The strategies are based on conventional breeding and advanced molecular techniques used by plant physiologists, and are discussed using specific case studies to illustrate their potential. The book emphasizes the effects of environmental factors on specific stages of plant development, and discusses the role of plant growth regulators, nutrients, osmoprotectants and antioxidants in counteracting their adverse affects. Synthesising updated information on mechansisms of stress tolerance at cell, tissue and whole-plant level, this book provides a useful reference text for post graduate students and researchers involved in the fields of stress physiology and plant physiology in general, with additional readership amongst researchers in horticulture, agronomy, crop science, conservation, environmental management and ecological restoration.

The world has become obsessed with the Western notions of progress, development, and globalization, the latter a form of human and economic homogenization. These processes, through the aegis of the United Nations, are comparatively monitored. Those nations deemed to be ‘lagging behind’ are then provided with foreign aid and developmental assistance. For nearly seventy years, India has sought its place in this global endeavour; yet, even today, abject poverty and backwardness can be observed in districts in almost every state; with the highest concentration of such districts found in the state of Bihar and a cultural enclave, known as Mithila. Development in India has been elusive because it is difficult to define; and because the Western concepts of development and progress have no absolute equivalents within many non-Western settings. As a consequence, development programmes often fail because they are unable to ask the right questions, but equally important is the political economy derived from foreign aid. For politicians, there is no long-term benefit to be derived from successful development. In general, foreign aid only serves to corrupt governments and politicians and, in the end, does very little for those who need help. The struggling states of Bihar and Mithila serve as extreme examples of India‘s problems. Development here has been thwarted by a hereditary landed aristocracy supported by religion, casteism, custom, social stratification, tradition, and patterns of behaviour that can be traced back millennia. In turn, all these have been masterfully manipulated by co-opted politicians, who have turned politics into a veritable art form as this volume comprehensively demonstrates.

In 2009, more than 40,000 people died prematurely in Sindh, Pakistan because of an illness associated with an environmental health risk. This means that almost one of every five deaths that occurred that year was caused by environmental factors. Loss of natural resources and impacts from natural disasters also represent development challenges. Increased salinity and waterlogging result in loss of agricultural crops. In addition, hydro-meteorological hazards recurrently affect Sindh, as illustrated by the devastating effects of the 2010 and 2011 floods. For Sindh's population, these problems mean pain and suffering, and reduced opportunities for economic advancement. The costs of all these phenomena are equivalent to 10% of Sindh's Gross Domestic Product. Climate change may exacerbate these challenges. Sindh's environmental and climate change problems call for urgent responses. A number of feasible interventions could be carried out to address the categories of environmental degradation that have the highest impacts on Sindh's population. Many of those interventions have positive benefit-cost ratios, meaning that every rupee invested in them would result in health and social benefits worth more than one rupee. Addressing these challenges also calls for targeted institutional strengthening and policy improvements, particularly after the 18th Constitutional Amendment devolved environmental management responsibilities to provincial governments. The underlying goal of this book is to facilitate and stimulate sharing of information on these phenomena, and to provide an interdisciplinary framework for bringing about improved environmental conditions in Sindh. It includes a methodology that enables the identification of environmental and climate change priority problems; the analysis of interventions to address such problems; the establishment of a social learning mechanism to continuously improve Sindh's responses and build resilience in the face of climate variability and change; and opportunities for the potential involvement of different stakeholder groups to decisively tackle climate change and deteriorating environmental conditions.
