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

Agricultural land suitability analysis: State-of-the-art and outlooks for integration of climate change analysis
TL;DR: In this paper, the impact of climate change on future land suitability and how this can be addressed or integrated into ALSA methods is discussed, and the authors emphasize that incorporating current and future climate change projections in ALSA is the way forward for sustainable or optimum agriculture and food security.

Estimating wheat yields in Australia using climate records, satellite image time series and machine learning methods
TL;DR: In this paper, the authors provided accurate estimates of actual wheat yields across the Australian wheat belt based on machine-learning regression methods, climate records and satellite image time series, and two ensembles of support vector regression with radial basis function emerged as the single best learner.

Assessment of nitrate leaching loss on a yield-scaled basis from maize and wheat cropping systems
TL;DR: In this article, the authors conducted a meta-analysis on 32 published studies reporting both NO3ⓘ − leaching losses and crop yields in the maize (N = 20) and wheat (N= 12) systems.

Food Security and the Dynamics of Wheat and Maize Value Chains in Africa and Asia
TL;DR: In this paper, the case of wheat and maize value chains and their contribution to food security in Africa and Asia is reviewed, where the authors identify drivers transforming food systems and disentangle their effects on food security.

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.
