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

Mesophyll photosynthesis and guard cell metabolism impacts on stomatal behaviour
TL;DR: The possible role of various metabolites including sucrose and malate and new evidence that improvements in WUE have been made by manipulating sucrose metabolism within the guard cells are explored.

Closing the yield gap could reduce projected greenhouse gas emissions: a case study of maize production in China.
Zhenling Cui,Shanchao Yue,Guiliang Wang,Qingfeng Meng,Liang Wu,Zhiping Yang,Qiang Zhang,Shiqing Li,Fusuo Zhang,Xinping Chen +9 more
TL;DR: On-farm observations indicate that closing the yield gap alongside efficient N management should therefore be prominent among a portfolio of strategies to meet food demand while reducing GHG intensity at the same time.

Comparative terrestrial feed and land use of an aquaculture-dominant world.
Halley E. Froehlich,Claire A. Runge,Rebecca R. Gentry,Steven D. Gaines,Benjamin S. Halpern,Benjamin S. Halpern +5 more
TL;DR: This study simulates how different forms of aquaculture contribute and compare with feed and land use of terrestrial meat production and how spatial patterns might change by midcentury if diets move toward more cultured seafood and less meat.

Effects of Fertilizer Broadcasting on the Excessive Use of Inorganic Fertilizers and Environmental Sustainability
K.M. Rahman,Dunfu Zhang +1 more
TL;DR: In this article, the authors examined the effects of fertilizer broadcasting on excessive use of fertilizer and environmental risks in Bangladesh and found that the effect of broadcasting was strongly significant, at 1%.

Designing climate-resilient rice with ideal grain quality suited for high-temperature stress
Nese Sreenivasulu,Vito M. Butardo,Gopal Misra,Rosa Paula Cuevas,Roslen Anacleto,Polavarpu B. Kavi Kishor +5 more
TL;DR: It is demonstrated here that the emerging field of systems genetics can help fast-track the identification of novel alleles and gene targets that can be pyramided for the development of environmentally robust rice varieties that possess improved grain quality.

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.
