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: 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 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge generation and transfer mechanisms are being transformed in important and controversial ways. Investment in research and development has increased in response to recognition that scientific productivity is tightly connected to economic dynamism. Patent protection has been expanded in order to stimulate higher levels of private investment. Intellectual property rights held by public organizations and researchers are now increasingly transferred to private organizations to accelerate the diffusion and enhance the value of knowledge produced by public agencies and universities. Additionally, new institutions such as university offices of technology transfer, venture capital markets, and a variety of consortia in knowledge-intensive industries are being established throughout the United States and in other parts of the world. These changes have led to a repositioning of the state in systems of innovation and an increase in the proprietary character of technical information. The purpose of this book is to review and analyze i) contemporary transitions in agricultural knowledge generation and extension arrangements from an empirical perspective, and ii) emerging and contradictory perspectives as to how knowledge systems can be assessed effectively. The authors aim to provide the reader with a better understanding of the implications of new biotechnologies and new intellectual property rights regimes on public-private relations in science, the extent to which benefits from scientific knowledge are being appropriated by private sector actors, the diversity and possible outcomes of privatization initiatives in extension, and prospects for public goods production and ecological sustainability given contemporary trends. The book presents contrasting views on the degree of complementarity and substitution between private and public sector investments in research and extension. Recognizing that the labels `public' and `private' are incomplete and at times misleading descriptions of the structure and function of coordinating bodies in social systems, the analyses highlight ways in which public and private spaces and modes of functioning combine. In addition to illustrating a broad range of analytic methodologies useful for studying organizational questions in knowledge systems, the authors identify the implications of a range of past and potential institutional innovations.
Download or read book Impacts of Landscape Change on Water Resources written by Manoj K. Jha and published by MDPI. This book was released on 2020-11-13 with total page 180 pages. 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.

This book was released on 2023-09-12 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic development has long been acknowledged for its beneficial effects on human well-being. In the context of economic globalization and vertical specialization, increasing the quality of export products is more critical and necessary to export success and sustainable development. The product's quality is inextricably linked to its manufacture and production, which need various types of energy and raw materials. Meanwhile, the adoption of more environmentally friendly and cleaner energy sources contributes to the achievement of sustainable production. Therefore, product quality may provide a new perspective from which to investigate the systematic relationship between greener and renewable energy sources, sustainable production and environmental regulations, as well as the nature of export competitiveness. Generally, export product quality has referred to the quality of manufactured products within the product lines. Quality refers to the relative price of a country's varieties within their respective product lines. Product sophistication assesses the composition of the aggregate exports. Different varieties of same product as per quality level are being produced by several developing and emerging economies. Within any given product line, quality converges both conditionally and unconditionally to the world's benchmark; increases in institutional quality and human capital are associated with faster quality upgrading. In turn, faster growth in quality is associated with more rapid output growth.
