Rice blast (Magnaporthe oryzae) is a key concern in combating global food insecurity given the disease responsible for approximately 30% of rice production losses globally-the equivalent feeding 60 million people. These increase price and reduce consumer welfare security. staple crop more than half world's population so any reduction would have substantial beneficial effects on livelihoods. In 2012, researchers US began analyzing feasibility creating blast-resistant through cisgenic...
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...
This article presents a cradle-to-grave analysis of the United States fluid milk supply chain greenhouse gas (GHG) emissions that are accounted from fertilizer production through consumption and disposal packaging. Crop on-farm GHG were evaluated using public data 536 farm operation surveys. Milk processing collected 50 dairy plants nationwide. Retail consumer estimated primary data, design estimates, publicly available data. Total emissions, based primarily on 2007 to 2008 2.05 (90%...
A life cycle assessment was conducted to determine a baseline for environmental impacts of cheddar and mozzarella cheese consumption. Product loss/waste, as well consumer transport storage, is included. The study scope from cradle-to-grave with particular emphasis on unit operations under the control typical cheese-processing plants. SimaPro© 7.3 (PRé Consultants, Netherlands, 2013) used primary modeling software. ecoinvent inventory database background processes (Frischknecht Rebitzer, J...
Dairy farms in the United States are diverse and although regional dairy production farm strategy has been evaluated for environmental impact, a comprehensive national assessment is important to define priorities sustainable intensification. We estimated footprints of using process-level simulation cradle-to-farm gate life cycle assessment. representing sizes management practices found six regions were simulated with Integrated Farm System Model (IFSM). Regional determined as an average all...
Dairy farms in the United States have changed many ways over past 50 yr. Milk production efficiency has increased greatly, with ∼30% fewer cows producing about twice amount of milk today. Other improvements include increases crop yields, fuel farm equipment, and most resources used on (e.g. electricity, fuel, fertilizer). These led to changes environmental impact farms. Through simulation representative dairy 1971 2020, nutrient losses farmgate life cycle assessments greenhouse gas (GHG)...
Greenhouse gas (GHG) emissions were evaluated from crop production through the on-farm portion of milk supply chain for five regions in USA derived publicly available data and 536 surveys farm operations collected dairy nationwide. The weighted national average footprint at gate was 1.23 kg carbon dioxide equivalent (CO2e) per fat protein corrected (fat, 4%; 3.3%). Regional differences GHG produced can be primarily traced to management practices. Feed-to-milk conversion efficiency is shown...
There is an increasing need for life cycle data bio-based products, which becomes particularly evident with the recent drive greenhouse gas reporting and carbon footprinting studies. Meeting this challenging given that many bio-products have not yet been studied by assessment (LCA), those are specific limited to certain geographic regions. In attempt bridge gaps LCA practitioners can use either proxy sets (e.g., existing environmental apples represent pears) or extrapolated derive new pears...
Australia is one of the two largest exporting nations for beef and lamb in world USA a major export market both products. To inform Australian red meat industry regarding environmental performance exported food products, this study conducted first multi-impact analysis supply chains including all stages through to warehousing USA. A large, integrated dataset based on case farms regional survey was used model from representative production regions eastern Australia. Per kilogram retail-ready...
Livestock production is important for food security, nutrition, and landscape maintenance, but it associated with several environmental impacts. To assess the risk benefits arising from livestock production, transparent robust indicators are required, such as those offered by life cycle assessment. A central question in approaches how burden allocated to products manure that re-used agricultural production. incentivize sustainable use of manure, should be considered a co-product long not...
Bacterial Panicle Blight (BPB), caused by Burkholderia glumae, is a bacterial disease in rice (Oryza sativa) that reduces yield and quality for producers consequently creates higher market prices consumers. BPB the simultaneous occurrence of high daily minimum temperatures (~22°C) relative humidity (~77%), which may increase under current scenario global warming. This study hypothesized economic damage from warming cause an losses, though at decreasing rate per degree. Thus, this estimates...
Life cycle assessments of have been completed documenting the environmental sustainability beef, but these studies often focused on specific cattle production systems with an emphasis global warming potential. A need exists for a national-scale full life assessment beef through consumption in United States. Process level simulation archetypical throughout nation were combined information gathered harvest, processing, retail, and to provide inventory data cradle-to-grave assessment. set 18...
Data from 536 United States of America dairy farms were used to test algorithms for milk beef allocation. A wide range rations was represented, pasture-based large confined animal operations. Variety in the classes sent provided a very robust dataset. We report an empirical relationship causal allocation ratio (ARc) based on detailed analysis farm rations, allocate whole emissions between and beef: ARc = 1–4.39∙BMR; with BMR defined as kg sold per annually. USA green house gas allocated...
Due to its genetic similarity with commercial rice, red rice is one the most damaging weeds in direct seeding systems. Using an integrated approach estimate economic, environmental, and food security impact of infestation U.S. as empirical case study, we find that losses under a moderate scenario from 2002 2014 amount 5.7 million tons or 6%, environmental cost $457 million. The resulting production loss enough feed 12 additional people year. We extend these findings selected Asian countries...
