Download or read book COVID 19 Food System Frailties and Opportunities written by Claire Kremen and published by Frontiers Media SA. This book was released on 2023-11-21 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global coronavirus pandemic is revealing major weaknesses, inequities and system-wide risks in global food systems, giving renewed urgency to foster pathways to greater food system sustainability and resilience. Due to rising unemployment, supply chain disruptions and other responses to the pandemic, such as disruptions to social assistance programs in some countries, predictions suggest a near doubling of food insecurity globally. Nutritional changes are also occurring, as food availability and access changes, leading to substitution of dry, canned or processed foods for healthier, fresh ingredients, for some communities, and the reverse for others. These food security and nutritional changes are likely to be as impactful on human health as the virus itself. As a system-wide shock, the pandemic reveals weaknesses of global supply chains. The media highlighted empty supermarket shelves alongside food dumping in situations where producers locked into disappearing food service outlets were unable to access new markets. Farmers with long-standing reliance on migrant agricultural labor that can no longer travel across international borders under lockdown struggle to access support for the upcoming harvest season. The pandemic highlights well-known inequities for marginalized food systems employees; as essential workers are exposed to greater risks of contracting the virus in food-processing, agricultural and grocery store settings, but have little choice in accepting these conditions in order to keep these low-paying jobs. The pandemic reinforces another well-known food system inequity: marginalized and impoverished minorities often suffer from diet-related diseases (i.e. cardiovascular diseases, diabetes) and/or malnutrition that place them at greater risk of morbidity and mortality from the coronavirus. Lockdowns and border closures are reducing economic opportunities such as day labor and agricultural markets in some regions, such as much of Africa; ensuing risks of food and nutrition insecurity for vast segments of the population threaten to set back development, increase social conflict, and catalyze migration. Finally, the current pandemic shines a spotlight on the systemic risk of infectious diseases to emerge and become globalized through local bushmeat markets and international wildlife trade, and how wildlife hunting and trade is influenced by land use changes, including by industrial agriculture. At the same time, adaptive responses to the coronavirus illustrate how more resilient and sustainable food systems could evolve going forward. To avoid supply chain disruptions, communities are increasing their reliance on local food systems, including an increase in urban gardening and community-supported agriculture programs. Small-scale farmers are innovating to connect with buyers and with each other, including through new online marketing initiatives. Entrepreneurs are identifying foods that would otherwise be wasted and directing them to food banks. Retailers and wholesalers are re-configuring their distribution networks to shift food to where it is needed most. Food pantries, local producers and food businesses are also collaborating with municipal governments to address food security gaps arising from COVID-19 impacts.

Download or read book Root Zone Water Quality Model written by Lajpat Ahuja and published by Water Resources Publication. This book was released on 2000 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication comes with computer software and presents a comprehensive simulation model designed to predict the hydrologic response, including potential for surface and groundwater contamination, of alternative crop-management systems. It simulates crop development and the movement of water, nutrients and pesticides over and through the root zone for a representative unit area of an agricultural field over multiple years. The model allows simulation of a wide spectrum of management practices and scenarios with special features such as the rapid transport of surface-applied chemicals through macropores to deeper depths and the preferential transport of chemicals within the soil matrix via mobile-immobile zones. The transfer of surface-applied chemicals (pesticides in particular) to runoff water is also an important component.

Download or read book Conservation Agriculture written by L. García-Torres and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Available in PDF, EPUB and Kindle. Book excerpt: Precision conservation is a reality, and we are moving towards improved effectiveness of conservation practices by accounting for temporal and spatial variability within and off field. This is the first book to cover the application of the principles of precision conservation to target conservation practices across fields and watersheds. It has clearly been established that the 21st century will present enormous challenges, from increased yield demands to climate change. Without improved conservation practices it will not be possible to ensure food security and conservation effectiveness. Readers will appreciate the application of the precision conservation concept to increase conservation effectiveness in a variety of contexts, with a focus on recent advances in technology, methods, and improved results. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.
Download or read book Toward Sustainable Agricultural Systems in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2010-07-25 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.
