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

Integrated landscape approaches to managing social and environmental issues in the tropics: learning from the past to guide the future
James Reed,James Reed,Josh van Vianen,Elizabeth Deakin,Jos Barlow,Terry Sunderland,Terry Sunderland +6 more
TL;DR: It is suggested that, despite some barriers to implementation, a landscape approach has considerable potential to meet social and environmental objectives at local scales while aiding national commitments to addressing ongoing global challenges.

Consumer Attitudes Towards Environmental Concerns of Meat Consumption: A Systematic Review
Ruben Sanchez-Sabate,Joan Sabaté +1 more
TL;DR: The results show that consumers aware of the meat impact on the planet, willing to stop or significantly reduce meat consumption for environmental reasons, and who have already changed their meat intake for ecological concerns are a small minority.

Spatial decoupling of agricultural production and consumption: quantifying dependences of countries on food imports due to domestic land and water constraints
TL;DR: In this article, the authors quantified to what extent water and land constraints limit countries' capacities, at present and by 2050, to produce on their own territory the crop products that they currently import from other countries.

Food vs. fuel: the use of land for lignocellulosic 'next generation' energy crops that minimize competition with primary food production.
TL;DR: In this paper, the authors present the vision for bioenergy in terms of four major gains for society: a reduction in C emissions from the substitution of fossil fuels with appropriate energy crops, a significant contribution to energy security by reductions in fossil fuel dependence, for example, to meet government targets, new options that stimulate rural and urban economic development, and reduced dependence of global agriculture on fossil fuels.

Back into the Wild – Apply Untapped Genetic Diversity of Wild Relatives for Crop Improvement
TL;DR: This review highlights the significance of crop wild relatives for crop improvement by providing examples of CWRs that have been used to increase biotic and abiotic stress resistance/tolerance and overall yield in various crop species, and discusses the surge of advanced biotechnologies, such as next‐generation sequencing technologies and omics.

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.

Forecasting agriculturally driven global environmental change
David Tilman,Joseph Fargione,Brian G. Wolff,Carla M. D'Antonio,Andrew P. Dobson,Robert W. Howarth,David W. Schindler,William H. Schlesinger,Daniel Simberloff,Deborah L. Swackhamer +9 more
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.
