Global climate change is a natural process that currently appears to be strongly influenced by human activities, which increase atmospheric concentrations of greenhouse gases (GHG). Agriculture contributes about 20% of the world's global radiation forcing from carbon dioxide, methane and nitrous oxide, and produces 50% of the methane and 70% of the nitrous oxide of the human-induced emission. Managing Agricultural Greenhouse Gases synthesizes the wealth of information generated from the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) effort with contributors from a variety of backgrounds, and reports findings with important international applications. - Frames responses to challenges associated with climate change within the geographical domain of the U.S., while providing a useful model for researchers in the many parts of the world that possess similar ecoregions - Covers not only soil C dynamics but also nitrous oxide and methane flux, filling a void in the existing literature - Educates scientists and technical service providers conducting greenhouse gas research, industry, and regulators in their agricultural research by addressing the issues of GHG emissions and ways to reduce these emissions - Synthesizes the data from top experts in the world into clear recommendations and expectations for improvements in the agricultural management of global warming potential as an aggregate of GHG emissions

As the last quarter of 2015 begins, production data show that total red meat and poultry production, aggregated over the first three quarters of 2015, increased by less than 1 percent over the same period of 2014. In the first three quarters of 2015, beef production is about 3 percent below production in the same period last year. Cattle prices so far in 2015 have averaged almost 3 percent above prices in the same period of 2014. Production effects of disease outbreaks link the pork and poultry sectors, but in divergent directions: the pork sector continues to recover from the effects of porcine epidemic diarrhea (PEDv) outbreaks last year, with total production in the first three quarters of 2015 almost 8 percent ahead of the same period in 2014. The poultry sector is recovering from Highly Pathogenic Avian Influenza (HPAI), the effects of which has fallen so far on the turkey sector (2 percent lower production) and the egg sector (5 percent lower production). Turkey prices have averaged almost 6 percent above the same period last year; average egg prices are almost 36 percent above the same period of 2014. Broiler production is up in 2015 by 4 percent.

Farmland tenure shapes many farm decisions, including those related to production, conservation, and succession planning. The relatively advanced age of many farmers raises questions abut land ownership, especially how land will be transferred to the next generation of agricultural landowners and operators. This study provides a descriptive baseline analysis of land ownership and then focuses on more detailed aspects of land tenure, including non-operator landlords, rental agreements, the acquisition and transfer of land, and how decisionmaking is shared by landlords and their tenants. The report is designed to support broad discussions related to agricultural land ownership and to provide a starting point for more detailed statistical analysis. Figures and tables. This is a print on demand report.

For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).

This report is part of a multi-volume technical report series entitled, Running a Food Hub, with this guide serving as a companion piece to other United States Department of Agriculture (USDA) reports by providing in-depth guidance on starting and running a food hub enterprise. In order to compile the most current information on best management and operations practices, the authors used published information on food hubs, surveyed numerous operating food hubs, and pulled from their existing experience and knowledge of working directly with food hubs across the country as an agricultural business consulting firm. The report’s main focus is on the operational issues faced by food hubs, including choosing an organizational structure, choosing a location, deciding on infrastructure and equipment, logistics and transportation, human resources, and risks. As such, the guide explores the different decision points associated with the organizational steps for starting and implementing a food hub. For some sections, sidebars provide “decision points,” which food hub managers will need to address to make key operational decisions. This illustrated guide may assist the operational staff at small businesses or third-party organizations that may provide aggregation, marketing, and distribution services from local and regional producers to assist with wholesale, retail, and institution demand at government institutions, colleges/universities, restaurants, grocery store chains, etc. Undergraduate students pursuing coursework for a bachelor of science degree in food science, or agricultural economics may be interested in this guide. Additionally, this reference work will be helpful to small businesses within the food trade discipline.
