This book was released on 2012 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: While agricultural production statistics are reported on a geopolitical - often national - basis we often need to know the status of production or productivity within specific sub-regions, watersheds, or agro-ecological zones. Such re-aggregations are typically made using expert judgments or simple area-weighting rules. We describe a new, entropy-based approach to making spatially disaggregated assessments of the distribution of crop production. Using this approach tabular crop production statistics are blended judiciously with an array of other secondary data to assess the production of specific crops within individual "pixels" - typically 25 to 100 square kilometers in size. The information utilized includes crop production statistics, farming system characteristics, satellite-derived land cover data, biophysical crop suitability assessments, and population density. An application is presented in which Brazilian state level production statistics are used to generate pixel level crop production data for eight crops. To validate the spatial allocation we aggregated the pixel estimates to obtain synthetic estimates of municipio level production in Brazil, and compared those estimates with actual municipio statistics. The approach produced extremely promising results. We then examined the robustness of these results compared to short-cut approaches to spatializing crop production statistics and showed that, while computationally intensive, the cross-entropy method does provide more reliable estimates of crop production patterns.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation agriculture is a sustainable production model that not only optimizes crop yields, but also reaps economic and environmental benefits as well. The adoption of successful conservation agriculture methods has resulted in energy savings, higher organic matter content and biotic activity in soil, increased crop-water availability and thus resilience to drought, improved recharge of aquifers, less erosion, and reduced impacts from the weather associated with climate change in general. Agricultural Impacts of Climate Change examines several important aspects of crop production, such as climate change, soil management, farm machinery, and different methods for sustainable conservation agriculture. It presents spatial distribution of a daily, monthly and annual precipitation concentration indices, Diffuse Reflectance Fourier Transform Infrared Spectroscopy for analyzing the organic matter in soil, and adaptation strategies for climate-related plant disease scenarios. It also discusses solar energy-based greenhouse modeling, precision farming using remote sensing and GIS, and various types of machinery used for conservation agriculture. Features: Examines the effects of climate change on agriculture and the related strategies for mitigation through practical, real-world examples Explores innovative on-farm technology options to increase system efficiency resulting in improved water usage Presents examples of precision farming using climate-resilient technologies

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores the interplay between the biophysical and economic geographies of climate change impacts on agriculture. It does so by bridging the extensive literature on climate impacts on yields and physical productivity in global crop production, with the literature on the role of adaptation through international trade in determining the consequences of climate change impacts. Unlike previous work in this area, instead of using a specific crop model or a set of models, we employ a statistical meta-analysis that encompasses all studies available to the IPCC-AR5 report. This permits us to isolate specific elements of the spatially heterogeneous biophysical geography of climate impacts, including the role of initial temperature, differential patterns of warming, and varying crop responses to warming across the globe. We combine these climate impact estimates with the Global Trade Analysis Project model of global trade in order to estimate the national welfare changes that are decomposed into three components: the direct (biophysical impact) contribution to welfare, the terms of trade effect, and the allocative efficiency effect. We find that when we remove the spatial variation in climate impacts, the terms of trade impacts are cut in half. Given the inherent heterogeneity of climate impacts in agriculture, this points to the important role of trade in distributing the associated welfare impacts. When we allow the biophysical impacts to vary across the empirically estimated uncertainty range taken from the meta-analysis, we find that the welfare consequences are highly asymmetric, with much larger losses at the low end of the yield distribution. This interaction between the magnitude and heterogeneity of biophysical climate shocks and their welfare effects highlight the need for detailed representation of both in projecting climate change impacts.

This book was released on 2018-11-29 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change poses a threat to food security and nutrition, largely through its impacts on agricultural production. To help developing countries identify where adaptation measures are most needed, IFPRI conducted a multiyear study to assess the potential impact of climate change on the agriculture sector through 2050, taking into account the likely landscape of political and economic challenges that policy makers will face. The study integrated results from climate and economic models, and included detailed biophysical and bioeconomic analyses of Guatemala, Honduras, El Salvador, Nicaragua, and Costa Rica in Central America and Colombia and Peru in the Andean region of South America. Analysis was done at a 50-kilometer resolution for a detailed distribution of the direct climate shocks, and at the country level to show aggregate economic shocks.

Available in PDF, EPUB and Kindle. Book excerpt: Wracked by poverty, famine, and drought, Africa is typically represented as agriculturally stagnant, backward, and crisis-prone. Living Under Contract, however, highlights the dynamic, changing character of sub-Saharan agrarian systems by focusing on contract farming. A relatively new and increasingly widespread way of organizing peasant agriculture, contract farming promotes production of a wide variety of crops--from flowers to cocoa, from fresh vegetables to rice--under contract to agribusinesses, exporters, and processers. The proliferation of African growers producing under contract is in fact part of broader changes in the global agro-food system. In this examination of agricultural restructuring and its effect upon various African societies, editors Peter Little and Michael Watts bring together anthropologists, economists, geographers, political scientists, and sociologists to explore the origins, forms, and consequences of contract production in several African countries, particularly Kenya, the Gambia, Zimbabwe, and the Ivory Coast. Documenting how contract production links farmers, agribusiness, and the state, the contributors examine problematic aspects of this method of agrarian reform. Their case studies, based on long-term field work and analysis on the village and household level, chart the complex effects of contract production on the organization of work and the labor process, rural inequality, gender relations, labor markets, local accumulation strategies, and regional development. Living Under Contract reveals that contract farming represents a distinctive form in which African growers are incorporated into national and world markets. Contract production, which has been a central feature of the agricultural landscape in the advanced capitalist states, is an emerging strategy for "capturing peasants" and for confronting the agrarian question in the late twentieth century.

This book was released on 2021-03-17 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: On top of a decade of exacerbated disaster loss, exceptional global heat, retreating ice and rising sea levels, humanity and our food security face a range of new and unprecedented hazards, such as megafires, extreme weather events, desert locust swarms of magnitudes previously unseen, and the COVID-19 pandemic. Agriculture underpins the livelihoods of over 2.5 billion people – most of them in low-income developing countries – and remains a key driver of development. At no other point in history has agriculture been faced with such an array of familiar and unfamiliar risks, interacting in a hyperconnected world and a precipitously changing landscape. And agriculture continues to absorb a disproportionate share of the damage and loss wrought by disasters. Their growing frequency and intensity, along with the systemic nature of risk, are upending people’s lives, devastating livelihoods, and jeopardizing our entire food system. This report makes a powerful case for investing in resilience and disaster risk reduction – especially data gathering and analysis for evidence informed action – to ensure agriculture’s crucial role in achieving the future we want.

This book was released on 2019-07-11 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although formal social impact assessment of changing technologies in U.S. agriculture is still in its infancy, scholars have been documenting the effects of new technology throughout the twentieth century. In this collection, Prcfessors Berardi and Geisler bring together historically relevant research and a carefully chosen cross section of contemporary work. Their review of the literature is followed by an evaluation of the effects of mechanization on labor and production, written in 1904, which provides a backdrop for papers from the 1940s and 1950s examining the mechanization of agriculture in the South, in the Midwest, and in rural areas in general. Subsequent chapters offer present-day insights on such topics as the socioeconomic consequences of automated vegetable and tobacco harvesting, center-pivot irrigation, and organic and no-till cultivation. The authors also look at compensation and adjustment programs for displaced labor, the relationship between technology and agribusiness growth, and the effectiveness of university programs that prepare students to perform social impact assessments in agriculture. The edited proceedings of a spirited roundtable discussion on new directions for the study of the social impacts of farm technology and the political economy of agriculture provide the thought-provoking conclusion to this overview of the field.

Available in PDF, EPUB and Kindle. Book excerpt: Changes in land use and land cover can have many drivers, including population growth, urbanization, agriculture, demand for food, evolution of socio-economic structure, policy regulations, and climate variability. The impacts of these changes on water resources range from changes in water availability (due to changes in losses of water to evapotranspiration and recharge) to degradation of water quality (increased erosion, salinity, chemical loadings, and pathogens). The impacts are manifested through complex hydro-bio-geo-climate characteristics, which underscore the need for integrated scientific approaches to understand the impacts of landscape change on water resources. Several techniques, such as field studies, long-term monitoring, remote sensing technologies, and advanced modeling studies, have contributed to better understanding the modes and mechanisms by which landscape changes impact water resources. Such research studies can help unlock the complex interconnected influences of landscape on water resources in terms of quantity and quality at multiple spatial and temporal scales. In this Special Issue, we published a set of eight peer-reviewed articles elaborating on some of the specific topics of landscape changes and associated impacts on water resources.
