Download or read book Fertilizer Quality and its Impacts on Technical Efficiency and Use Intensity in the North China Plain written by Ling Yee Khor and published by Cuvillier Verlag. This book was released on 2014-11-19 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertilizer has helped the growth of agriculture for decades. However, its overuse in some regions has caused environmental and health problems due to pollution and contamination of groundwater. Fertilizer quality is another cause for concern in many countries, as the actual nutrient content may not match the labeled content on the packaging. The North China Plain is a region affected by both fertilizer overuse and quality problems. This study delves into the issue using economic models and survey data of farm households. Is the effectiveness of fertilizer overstated? How do farmers respond to uncertainty in fertilizer quality? Can they differentiate between good and poor quality fertilizer?
Download or read book Realization of Ecological Product Value Land Use Change and Environment written by Hualin Xie and published by Frontiers Media SA. This book was released on 2024-04-15 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Establishing the mechanism of realizing the value of ecological product is an important way to realize land use change, agricultural production transformation and reduce environmental pollution. In recent years, consumers' demand for ecological products has been increasing while the supply is seriously insufficient. The realization of ecological product value faces various bottlenecks, including the realization mechanism of ecological product value, land use variation and the temporal dynamics of land use change, and the driving forces behind land dynamics and their socio-ecological feedbacks. Meanwhile, the relationship between the realization of ecological product value, land use transformation and changes in agricultural production mode are still unclear. In the process of realizing the value of ecological products, how to realize agricultural production and land use transformation, and environmental improvement is also a constant concern to be solved desperately.

Download or read book 2012 Global Food Policy Report written by International Food Policy Research Institute and published by Intl Food Policy Res Inst. This book was released on 2013 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2012 Global Food Policy Report is the second in an annual series that provides an in-depth look at major food policy developments and events. Initiated in response to resurgent interest in food security, the series offers a yearly overview of the food policy developments that have contributed to or hindered progress in food and nutrition security. It reviews what happened in food policy and why, examines key challenges and opportunities, shares new evidence and knowledge, and highlights emerging issues. In 2012, world food security remained vulnerable. While talk about hunger and malnutrition was plentiful, it remains to be seen whether current and past commitments to invest in agriculture, food security, and nutrition will be met. New data from the Food and Agriculture Organization of the United Nations suggest that the world will fall short of achieving the first Millennium Development Goal of halving the prevalence of undernutrition by 2015. Translating commitments into action is thus even more urgent.

Download or read book Resources Use Efficiency in Agriculture written by Sandeep Kumar and published by Springer Nature. This book was released on 2020-09-18 with total page 762 pages. 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 Food Outlook Biannual Report on Global Food Markets written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-06-10 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Against the background of fast expanding trade and a surge in food import bills, which has come to characterise much of developments shaping global food markets in 2020/21, early forecasts for 2021/22 point to resilient food trade and a continuation of strong international prices amidst many supply and demand uncertainties. This report provides supply and demand forecasts for basic foodstuffs, fish and fishery products along with price analysis and policy information. The report’s special feature of this report puts recent trends in global food trade under the spotlight, with particular focus on how commodity flows have measured-up during the COVID-19 pandemic. Contrary to widespread predictions of a collapse in global markets, recent data show that trade continues to reach new heights. A novel metric is introduced that better captures the price momentum underway in international markets. Food Outlook is published by the Markets and Trade Division of FAO as part of the Global Information and Early Warning System (GIEWS). It is a biannual publication (November and June) focusing on developments in global food markets. Food Outlook maintains a close synergy with another major GIEWS publication, Crop Prospects and Food Situation, especially with regard to the coverage of cereals. Food Outlook is available in English. The summary section is also available in Arabic, Chinese, French, Russian and Spanish

Download or read book Integrated nutrients management An approach for sustainable crop production and food security in changing climates written by Amanullah and published by Frontiers Media SA. This book was released on 2024-06-20 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil health and fertility are continuously declining due to the removal of essential plant nutrients from the soils in the current changing climate scenario. Due to less soil organic carbon (SOC) and growing of high-yielding varieties and hybrids further increases deficiencies of both macro and micronutrients that had a negative impact on soil health, crop productivity, food security, and growers. Integrated nutrients management not only increases crop productivity and growers' income but also increases soil fertility, health, and sustainability in changing climates. Integrated nutrients management (INM) refers to the maintenance of soil fertility and improvement in crop productivity with the application of plant nutrients through the combined application of organic fertilizers (animal manures and plant residues), chemical fertilizers (urea, SSP, DAP, etc.) and bio-fertilizers (beneficial microbes).
