Download or read book Resource Use Patterns and Resource Use Efficiency in Crop Agriculture written by Arun Kumar Nandi and published by LAP Lambert Academic Publishing. This book was released on 2012-05 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rational use of agricultural resources is very crucial for increase in agricultural production, productivity and farm income, for improvement in the living standard of rural masses and for growth with social justice. This book tries to address various issues in crop agriculture and examines resource use patterns and resource use efficiency in West Bengal agriculture where farming system is dominated by the marginal farmers. A modest attempt has been made in this book to measure farm level overall productive efficiency in terms of unit cost of production on application of three sigma rule and specific input-use efficiency based on stochastic frontier production function analysis and curve fitting to reduce the gap between theory and practice in this regard. Efficiency differentials across size groups of farms by different approaches and structural change and labour absorption in agriculture are examined based on aggregated and disaggregated data at secondary and primary levels. Academicians, researchers, and policy makers in the field of agricultural economics will be the beneficiaries of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Achieving zero hunger and food security is a top priority in the United Nations Development Goals (UNDGs). In an era characterized by high population growth and increasing pressure on agricultural systems, efficiency in the use of natural resources has become central to sustainable agricultural practices. Fundamentally speaking, eco-efficiency is about maximizing agricultural outputs, in terms of quantity and quality, using less land, water, nutrients, energy, labor, or capital. The concept of eco-efficiency involves both the ecological and economic aspects of sustainable agriculture. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape, as well as farmers’ economic needs. This book examines the latest eco-efficient practices used in agro-systems. Drawing upon research and examples from around the world, it offers an up-to-date overview, together with insights into directly applicable approaches for poly-cropping systems and landscape-scale management to improve the stability of agricultural production systems, helping achieve food security. The book will be of interest to educators, researchers, climate change scientists, capacity builders and policymakers alike. It can also be used as additional reading material for undergraduate and graduate courses on agriculture, forestry, soil science, and the environmental sciences.

Download or read book Sustainable Intensification written by Jules N. Pretty and published by Routledge. This book was released on 2012-06-25 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Download or read book Coupling Field Data with Modeling Tools to Evaluate Resource Use Efficiency and Environmental Impacts in California Agriculture written by Cara N. Fertitta and published by . This book was released on 2017 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sustainability of California agriculture depends on its ability to adapt to climate change and to mitigate it. Though field and laboratory experiments provide important data to this end, they require time and resources that limit the pace of progress. Coupling these data with modeling tools can accelerate agroecological research and highlight important directions for more comprehensive in vivo studies. Here, we use a combination of field data and modeling tools improve our understanding of stress tolerance and to rapidly assess the environmental impacts of various agricultural products. Chapter one evaluates water use dynamics in Sorghum bicolor cv. (Photoperiod LS) grown in California's Imperial Valley (IV) and the implications for stress tolerance. Coupling field data with an optimization model, we found sorghum to exhibit high heat tolerance at the expense of water use efficiency (WUE). However, the extent to which WUE was compromised varied in response to soil water status, suggesting sorghum adjusts its water use patterns depending on the type and severity of stress present. In chapter two, we assessed the environmental impacts associated with biofuel production using IV sorghum as a feedstock. We used field data to parameterize a crop model, allowing us to evaluate a wide range of nitrogen (N) management scenarios for feedstock production. Crop model output was coupled with life cycle assessment models to quantify the well-to-wheel environmental impacts of each production scenario. Overall, biofuels from IV sorghum had about 1/3 the global warming potential (GWP) of gasoline, but had much greater impacts to local air and water pollution. Efficient use of N was an important pathway for mitigating adverse impacts. Using a similar experimental framework, chapter three evaluates the GWP of California rice under a range of irrigation schedules varying in the severity and frequency of drainage events during the growing season. Severe and frequent dry-downs provided the greatest greenhouse gas mitigation potential, but showed potential to reduce grain yields, compromising the advantages of this practice from a global perspective. Our work highlights the diverse and valuable contributions of data-model fusion in preparing California for the conditions and demands of twenty-first century agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: The National Research Council's Science and Technology for Sustainability Program hosted two workshops in 2011 addressing the sustainability challenges associated with food security for all. The first workshop, Measuring Food Insecurity and Assessing the Sustainability of Global Food Systems, explored the availability and quality of commonly used indicators for food security and malnutrition; poverty; and natural resources and agricultural productivity. It was organized around the three broad dimensions of sustainable food security: (1) availability, (2) access, and (3) utilization. The workshop reviewed the existing data to encourage action and identify knowledge gaps. The second workshop, Exploring Sustainable Solutions for Increasing Global Food Supplies, focused specifically on assuring the availability of adequate food supplies. How can food production be increased to meet the needs of a population expected to reach over 9 billion by 2050? Workshop objectives included identifying the major challenges and opportunities associated with achieving sustainable food security and identifying needed policy, science, and governance interventions. Workshop participants discussed long term natural resource constraints, specifically water, land and forests, soils, biodiversity and fisheries. They also examined the role of knowledge, technology, modern production practices, and infrastructure in supporting expanded agricultural production and the significant risks to future productivity posed by climate change. This is a report of two workshops.
