This book is a comprehensive volume dealing with climate change impacts on agriculture, and which can help guide the redesign of agricultural management and cropping systems. It includes mitigation techniques such as use of bioenergy crops, fertilizer and manure management, conservation tillage, crop rotations, cover crops and cropping intensity, irrigation, erosion control, management of drained wetlands, lime amendments, residue management, biochar and biotechnology. It also includes Management of GHG emissions Crop models as decision support tools QTL analysis Crop water productivity Impacts of drought on cereal crops Silvopastoral systems Changing climate impact on wheat-based cropping systems of South Asia Phosphorous dynamics under changing climate Role of bioinformatics The focus of the book is climate change mitigation to enhance sustainability in agriculture. We present various kinds of mitigation options, ways to minimize GHG emissions and better use of the latest techniques in conservation and environmental-sustainability.

This research investigates the complex relationship between agrobiodiversity and livelihoods in the Central Highlands of Mexico by studying the everyday lives of four key categories of actors: 1) small-scale commercially-oriented maize producers; 2) agricultural research scientists; 3) agricultural extension agents; and 4) maize populations. This inquiry is prompted by a seeming empirical paradox, according to leading theories of agricultural modernization: populations of genetically-diverse locally-bred varieties of maize, along with the diversity of knowledges and practices that maintain them, persistently dominate the small-scale farms of Mexico, even as these varieties are increasingly rendered obsolete, at least within the dictates of a global commodity market, by the recent economic transformations of agricultural modernization. The country's Central Highland region provides a unique opening for inquiry into these dynamic relationships. It is at once home to some of the world's foremost centers of maize research, which partner with regional and multinational biotechnology companies to aggressively promote the adoption of "modern" scientifically-bred maize varieties, and also to small agrarian communities that consistently and, in many cases, exclusively cultivate maize varieties they have bred themselves. Three major questions have been insufficiently explored in academic research: First, how do those involved in maize production, both directly and indirectly, conceive of and engage agrobiodiversity? Second, how do relationships to agrobiodiversity vary within and across maize-centered livelihoods? Third, how do these relationships shape development institutions, agricultural technologies and practices, and trajectories of agricultural change, and whose purposes do they serve as a result -- i.e., why do certain socioecological relationships emerge and persist? My dissertation research addresses these questions by examining the contradictions of agrobiodiversity and agricultural modernization in Mexico's Central Highlands through the perspectives and practical activities of the four groups, enumerated above, whose lives are implicated in the dynamics taking place. Bringing these perspectives together, I argue that processes of uneven agricultural development in the region are highly negotiated, with actors working from within and without existing social and institutional structures to pursue multiple, overlapping objectives. These tensions have produced a dynamic and contradictory landscape of persistent maize genetic diversity, for which adequate explanations are currently lacking. In this research, I find that maize diversity is persisting in the Amecameca Valley because farmers are maintaining economic diversity. This research also finds that, despite all rhetoric to the contrary, the current agricultural development projects at work in the region are undermining, rather than supporting, smallholder maize producer livelihoods.

This book is about climate change and its relation to agriculture and rural livelihoods. It starts by providing a basic understanding of climate change science followed by the relation of climate change to agriculture, the impact of which is discussed based on the particular impact of climate change on plant and animal physiology. The book further discusses the inclusion of the agriculture sector in various international climate change negotiations. It also reviews the cost and opportunities for agricultural projects through international climate change regimes, specifically the Clean Development Mechanism under the Kyoto Protocol. With this background, the book finally proceeds to an explanation of the methodologies used to assess the impact of climate change on agriculture and empirically discusses its impact on agriculture and rural livelihoods in Nepal.
