TLDR
A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here.Abstract:
Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably. A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here.read more

Mapping paddy rice planting area in rice-wetland coexistent areas through analysis of Landsat 8 OLI and MODIS images
Yuting Zhou,Xiangming Xiao,Yuanwei Qin,Jinwei Dong,Geli Zhang,Weili Kou,Cui Jin,Jie Wang,Xiangping Li +8 more
TL;DR: The results of this study demonstrate the potential of the phenology-based paddy rice mapping algorithm, via integrating MODIS and Landsat 8 OLI images, to map paddyrice fields in complex landscapes of paddy Rice and natural wetland in the temperate region.

Energy and protein feed-to-food conversion efficiencies in the US and potential food security gains from dietary changes
TL;DR: In this article, the authors quantified caloric and protein conversion efficiencies for US livestock categories, and then used these efficiencies to calculate the food availability gains expected from replacing beef in the US diet with poultry, a more efficient meat, and a plant-based alternative.

An exploratory study of food waste management practices in the UK grocery retail sector
TL;DR: In this article, the authors investigate how managers of major UK grocery retailers address the problem of food waste in their day-to-day operations and reveal that while food waste recycling and price reductions are mainstream, food donations are ad-hoc and largely occur at managerial discretion.

The alignment of agricultural and nature conservation policies in the European Union
TL;DR: The European response to the competing demands for land resources may offer lessons globally as demands on rural land increase.

Land Clearing and the Biofuel Carbon Debt
TL;DR: Converting rainforests, peatlands, savannas, or grasslands to produce food crop–based biofuels in Brazil, Southeast Asia, and the United States creates a “biofuel carbon debt” by releasing 17 to 420 times more CO2 than the annual greenhouse gas reductions that these biofuel reductions would provide by displacing fossil fuels.
The state of food insecurity in the world 2011: how does international price volatility affect domestic economies and food security?
TL;DR: In this paper, the authors highlight the differential impacts that the world food crisis of 2006-2008 had on different countries, with the poorest being most affected, and present policy options to reduce volatility in a cost-effective manner and to manage it when it cannot be avoided.

TL;DR: Should past dependences of the global environmental impacts of agriculture on human population and consumption continue, 109 hectares of natural ecosystems would be converted to agriculture by 2050, accompanied by 2.4- to 2.7-fold increases in nitrogen- and phosphorus-driven eutrophication of terrestrial, freshwater, and near-shore marine ecosystems.
