Reducing food’s environmental impacts through producers and consumers

TL;DR: Cumulatively, the findings support an approach where producers monitor their own impacts, flexibly meet environmental targets by choosing from multiple practices, and communicate their impacts to consumers.

TL;DR: In this paper, a new global food emissions database (EDGAR-FOOD) was developed to estimate greenhouse gas (GHG; CO2, CH4, N2O, fluorinated gases) emissions for the years 1990-2015, complemented with land use/land use change emissions from FAOSTAT emissions database.

Comparative analysis of environmental impacts of agricultural production systems, agricultural input efficiency, and food choice
Abstract: Global agricultural feeds over 7 billion people, but is also a leading cause of environmental degradation. Understanding how alternative agricultural production systems, agricultural input efficiency, and food choice drive environmental degradation is necessary for reducing agriculture's environmental impacts. A meta-analysis of life cycle assessments that includes 742 agricultural systems and over 90 unique foods produced primarily in high-input systems shows that, per unit of food, organic systems require more land, cause more eutrophication, use less energy, but emit similar greenhouse gas emissions (GHGs) as conventional systems; that grass-fed beef requires more land and emits similar GHG emissions as grain-feed beef; and that low-input aquaculture and non-trawling fisheries have much lower GHG emissions than trawling fisheries. In addition, our analyses show that increasing agricultural input efficiency (the amount of food produced per input of fertilizer or feed) would have environmental benefits for both crop and livestock systems. Further, for all environmental indicators and nutritional units examined, plant-based foods have the lowest environmental impacts; eggs, dairy, pork, poultry, non-trawling fisheries, and non-recirculating aquaculture have intermediate impacts; and ruminant meat has impacts ~100 times those of plant-based foods. Our analyses show that dietary shifts towards low-impact foods and increases in agricultural input use efficiency would offer larger environmental benefits than would switches from conventional agricultural systems to alternatives such as organic agriculture or grass-fed beef.

Multiple benefits of legumes for agriculture sustainability: an overview
TL;DR: In this paper, the authors proposed that legumes have high potential for conservation agriculture, being functional either as growing crop or as crop residue, and they also perform well in conservation systems, inter-cropping systems, which are very important in developing countries as well as in low-input and low-yield farming systems.

Comparing environmental impacts for livestock products: A review of life cycle assessments
M. de Vries,I.J.M. de Boer +1 more
TL;DR: Differences in environmental impact among pork, chicken, and beef can be explained mainly by 3 factors: differences in feed efficiency, differences in enteric CH4 emission between monogastric animals and ruminants, and differences in reproduction rates.
