The environmental impacts of beef cattle production and their effects on the overall sustainability have become a national international concern. Our objective was to quantify important in United States. Surveys visits farms, ranches feedlots were conducted throughout seven regions (Northeast, Southeast, Midwest, Northern Plains, Southern Northwest Southwest) determine common practices characteristics production. These data along with other information sources used create about 150...
The need to assess the sustainability attributes of United States beef industry is underscored by its importance food security locally and globally. A life cycle assessment (LCA) US value chain was conducted develop baseline information on environmental impacts includ`ing metrics cradle-to-farm gate (feed production, cow-calf, feedlot operations) post-farm (packing, case-ready, retail, restaurant, consumer) segments. Cattle production (cradle-to-farm gate) data were obtained using integrated...
The growing importance of rice globally over the past three decades is evident in its strategic place many countries’ food security planning policies. Still, cultivation emits substantial greenhouse gases (GHGs). Indica and Japonica sub-species Oryza sativa L. are mainly grown, with holding largest market share. awareness, economics, acceptability a food-insecure rice-consuming population were surveyed. impact parboiling on was studied factors which most impacted stickiness investigated...
A comprehensive national assessment of the sustainability beef is being conducted by U.S. industry. The first 7 regions to be analyzed Kansas, Oklahoma, and Texas. survey visits throughout region provided data on common production practices. From these data, representative ranch feedyard operations were defined simulated for varying climate soil conditions using Integrated Farm System Model. These simulations predicted environmental impacts each operation including cradle-to-farm gate...
A comprehensive life cycle assessment of United States beef will provide benchmarks and identify opportunities for improvement. On-going region-specific data collection is characterizing cattle production practices a more accurate assessment. This study reports information obtained via online surveys on-site visits from 2 7 regions: the Northern Plains (Nebraska, North Dakota, South Dakota) Midwest (Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Wisconsin). Ranch responses (n = 512)...
The production of hydrogen fuels, via water splitting, is practical relevance for meeting global energy needs and mitigating the environmental consequences fossil-fuel-based transportation. Water photoelectrolysis has been proposed as a viable approach generating hydrogen, provided that stable inexpensive photocatalysts with conversion efficiencies over 10% can be discovered, synthesized at scale, successfully deployed (Pinaud et al., Energy Environ. Sci., 2013, 6, 1983). While number...
An assessment of the sustainability beef production in Kansas, Oklahoma, and Texas region requires information on their practices. A voluntary survey was conducted for ranches feedyards along with site visits to gather Responses represented 0.8% cows maintained 9% cattle finished region, a wide range size types operations. Most characteristics cow-calf stocker did not vary much across states, but there were differences cow stocking rates forage from wetter east side drier, semiarid...
A comprehensive life cycle assessment of the beef value chain in United States is being conducted to provide benchmarks and identify opportunities for improvement. Region-specific data are collected accurately characterize cattle production practices. This study reports information obtained via surveys on-site visits from 2 7 regions: Northwest (Idaho, Montana, Oregon, Washington, Wyoming) Southwest (Arizona, California, Colorado, Nevada, New Mexico, Utah). Responses ranches (defined as...
As part of the United States Beef Sustainability Program, a nationwide characterization regional beef production practices was conducted. Data on cattle were gathered through voluntary surveys and on-site visits in Northeast Southeast, last 7 cattle-producing regions studied. Participating farms ranches (n = 817) represented 1.2 1.0% cows respectively. Responses from finishing operations 55) 4 23% fed Herd sizes reported larger Southeast than Northeast; however, stocking rates similar....
Reuse of wastewater for aquaculture improves the efficient use water and promotes sustainability but potential effects endocrine disrupting compounds including estrogens in are an emerging challenge that needs to be addressed. We examined biological wastewater-borne on African catfish (Clarias gariepinus) raised a stabilization pond (WSP) functioning municipal treatment plant, polishing (WWP) dysfunctional reference (RP) unimpacted by wastewater, located Ghana. Measurements estrogen...
Optimal placement of sensors in protected cultivation systems to maximize monitoring and control capabilities can guide effective decision-making toward achieving the highest levels productivity other desirable outcomes. Reinforcement learning, unlike conventional machine learning methods such as supervised does not require large, labeled datasets thereby providing opportunities for more efficient unbiased design optimization. With objective determining optimal locations a greenhouse,...
Irregular changes in the internal climates of protected cultivation systems can prevent attainment optimal yield when environmental conditions are not adequately monitored and controlled. Key to indoor environment monitoring control potentially reducing operational costs strategic placement an number sensors using a robust method. A multi-objective approach based on supervised machine learning was used determine installation positions system. Specifically, gradient boosting algorithm, form...
A comprehensive life cycle assessment of the US beef value chain requires collection region-specific data for accurate characterization country's diverse production practices. Cattle in Hawaii is very different from rest country due to its unique ecosystem and geographic location. survey cattle producers provided information on herd size characteristics, grazing management, forage feed sources, marketing. Ranch responses represented 44% state's cows with operation sizes varying 5 10,000...
This chapter shows results obtained from analyzing samples of vegetables taken at the farm gate and selling points in Accra, Kumasi Tamale. Microbiological data are based on a total about 1,500 vegetable different sampling along distribution chain – gates categories sellers Tamale Kumasi. Fecal coliforms helminth eggs were mainly used as fecal contamination indicator organisms. For chemical contaminants, heavy metals pesticides irrigation water analyzed, while estrogens an example for...
Cradle-to-farm gate environmental impacts of beef production in two cattle producing regions were assessed as part an ongoing national sustainability study the U.S. value chain launched by Beef Checkoff. Region-specific data on common ranch and feedlot management practices characterized from producer surveys site visits each 10 states within Midwest Northern Plains regions. This information was used along with appropriate climate soil to simulate representative operations predict Integrated...
