The world's demand for food is expected to double within the next 50 years, while the natural resources that sustain agriculture will become increasingly scarce, degraded, and vulnerable to the effects of climate change. In many poor countries, agriculture accounts for at least 40 percent of GDP and 80 percent of employment. At the same time, about 70 percent of the world's poor live in rural areas and most depend on agriculture for their livelihoods. 'World Development Report 2008' seeks to assess where, when, and how agriculture can be an effective instrument for economic development, especially development that favors the poor. It examines several broad questions: How has agriculture changed in developing countries in the past 20 years? What are the important new challenges and opportunities for agriculture? Which new sources of agricultural growth can be captured cost effectively in particular in poor countries with large agricultural sectors as in Africa? How can agricultural growth be made more effective for poverty reduction? How can governments facilitate the transition of large populations out of agriculture, without simply transferring the burden of rural poverty to urban areas? How can the natural resource endowment for agriculture be protected? How can agriculture's negative environmental effects be contained? This year's report marks the 30th year the World Bank has been publishing the 'World Development Report'.

As economic crises, growing inequality and climate change prompt a global debate on the meaning and trajectory of development, increasing attention is focusing on 'social and solidarity economy' as a distinctive approach to sustainable and rights-based development. While we are beginning to understand what social and solidarity economy is, what it promises and how it differs from 'business as usual', we know far less about whether it can really move beyond its fringe status in many countries and regions. Under what conditions can social and solidarity economy scale up and scale out - that is, expand in terms of the growth of social and solidarity economy organizations and enterprises, or spread horizontally within given territories? Bringing together leading researchers, blending theoretical and empirical analysis, and drawing on experiences and case studies from multiple countries and regions, this volume addresses these questions. In so doing, it aims to inform a broad constituency of development actors, including scholars, practitioners, activists and policy makers.

PGPR have gained world wide importance and acceptance for agricultural benefits. These microorganisms are the potential tools for sustainable agriculture and the trend for the future. Scientific researches involve multidisciplinary approaches to understand adaptation of PGPR to the rhizosphere, mechanisms of root colonization, effects on plant physiology and growth, biofertilization, induced systemic resistance, biocontrol of plant pathogens, production of determinants etc. Biodiversity of PGPR and mechanisms of action for the different groups: diazotrophs, bacilli, pseudomonads, and rhizobia are shown. Effects of physical, chemical and biological factors on root colonization and the proteomics perspective on biocontrol and plant defence mechanism is discussed. Visualization of interactions of pathogens and biocontrol agents on plant roots using autofluorescent protein markers has provided more understanding of biocontrol process. Commercial formulations and field applications of PGPR are detailed.

This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

A Companion to Environmental Geography is the first book to comprehensively and systematically map the research frontier of 'human-environment geography' in an accessible and comprehensive way. Cross-cuts several areas of a discipline which has traditionally been seen as divided; presenting work by human and physical geographers in the same volume Presents both the current 'state of the art' research and charts future possibilities for the discipline Extends the term 'environmental geography' beyond its 'traditional' meanings to include new work on nature and environment by human and physical geographers - not just hazards, resources, and conservation geographers Contains essays from an outstanding group of international contributors from among established scholars and rising stars in geography

Recent changes in the global economy and in Southeast Asian national political economies have led to new forms of commodity production and new commodities. Using insights from political economy and commodity studies, the essays in Taking Southeast Asia to Market trace the myriad ways recent alignments among producers, distributors, and consumers are affecting people and nature throughout the region. In case studies ranging from coffee and hardwood products to mushroom pickers and Vietnamese factory workers, the authors detail the Southeast Asian articulations of these processes while also discussing the broader implications of these shifts. Taken together, the cases show how commodities illuminate the convergence of changing social forces in Southeast Asia today, as they transform the terms, practices, and experiences of everyday life and politics in the global economy.

Rents to Riches> focuses on the political economy of the detailed decisions that governments make at each step of the natural resource management (NRM) value chain. Many resource-dependent developing countries pursue seemingly shortsighted and suboptimal policies when extracting, taxing, and investing resource rents. The book contextualizes these micro-level outcomes with an emphasis on two central political economy dimensions: the degree to which governments can make credible intertemporal commitments to both resource developers and citizens, and the degree to which governments and inclined to turn resource rents into public goods. Almost 1.5 billion people live in the more than 50 World Bank client countries classified as resource-dependent. A detailed understanding of the way political economy characteristics affect the NRM decisions made in these countries by governments, extractive developers, and society can improve the design of interventions to support welfare-enhancing policy making and governance in the natural resource sectors. Featuring case study work from Africa (Angola, the Democratic Republic of Congo, Ghana, Niger, Nigeria), East Asia and Pacific (the Lao People's Democratic Republic, Mongolia, Timor-Leste), and Latin America and the Caribbean (Bolivia, Chile, Ecuador, Mexico, Trinidad an dTobago_, the book provides guidance for government clients, domestic stakeholders, and development partners committed to transforming natural resource into sustainable development riches.

A major task of our time is to ensure adequate food supplies for the world's current population (now nearing 7 billion) in a sustainable way while protecting the vital functions and biological diversity of the global environment. The task of providing for a growing population is likely to be even more difficult in view of actual and potential changes in climatic conditions due to global warming, and as the population continues to grow. Current projections suggest that the world's temperatures will rise 1.8-4.0 by 2100 and population may reach 8 billion by the year 2025 and some 9 billion by mid-century, after which it may stabilize. This book addresses these critical issues by presenting the science needed not only to understand climate change effects on crops but also to adapt current agricultural systems, particularly in regard to genetics, to the changing conditions. Crop Adaptation to Climate Change covers a spectrum of issues related to both crops and climatic conditions. The first two sections provide a foundation on the factors involved in climate stress, assessing current climate change by region and covering crop physiological responses to these changes. The third and final section contains chapters focused on specific crops and the current research to improve their genetic adaptation to climate change. Written by an international team of authors, Crop Adaptation to Climate Change is a timely look at the potentially serious consequences of climate change for our global food supply, and is an essential resource for academics, researchers and professionals in the fields of crop science, agronomy, plant physiology and molecular biology; crop consultants and breeders; as well as climate and food scientists.
