This paper takes as its starting point the mainstream projections that in future, global food production will need to increase by another 60–110% by 2050, to keep up with anticipated increases in human population and changes in diet (it should be noted, however, that the need and feasibility of such increases is contested (see), with many arguing that dietary change and waste reduction can reduce the need for production increases (see)).

The ‘2016 Food, Water, Energy and Climate Outlook’ by the MIT Joint Program on the Science and Policy of Global Change finds that even if commitments from the  COP21 climate agreement are kept, many staple crops in various regions are still at risk of crop failures through extreme events, but at the same time, yields in many regions are projected to increase.

Recent assessments have strongly suggested that meeting the widely agreed target of limiting global warming to less than 2°C will require the deployment of substantial carbon sinks in addition to measures to curb greenhouse gas (GHG) emissions. This perspective article examines the latest research and thinking on the ability of agricultural soil management to reduce GHG emissions and promote soils as carbon sinks, and the practical feasibility of implementing available soil management practices

Alternative cropping systems such as organic or conservation agriculture are often expected to lead to enhanced soil carbon storage as compared with conventional systems, and therefore to hold potential to contribute to climate change mitigation via carbon sequestration.

Permaculture is described here as a grassroots movement whose participants attempt to live in a sustainable way, taking inspiration from natural ecosystems in trying to live off the land as much as possible. The idea behind permaculture is to rely as much as possible on perennial crops, to recycle and reuse materials, and reduce waste.

According to the latest joint OECD-FAO report Food Outlook which analyses global food markets, the coming decade will likely see an end to a period of high agricultural prices, although prices are expected to rise for livestock relative to those for crops.

As the climate changes, and food demand increases, crop varieties suited to these conditions need to be developed. The authors of this paper warn that crops yields around the world could fall within a decade unless action is taken to speed up the introduction of new varieties. They propose three ways to improve matching of maize varieties in Africa to a warmed climate: reduce the BDA (the process of breeding, delivery and adoption), breed under elevated temperatures and act to mitigate climate change.

Taking as their starting point a hypothetical zero-deforestation for agricultural production, where people would refrain from clearing any further forests for agricultural purposes, the researchers behind this study look at both supply side and demand side measures to assess how changes in production and diet can assist in halting deforestation

More than three-quarters of the world's food crops are at least partly dependent on pollination and in many regions over 40 percent of the bees and the butterflies are threatened with extinction, according to a new report entitled Thematic Assessment of Pollinators, Pollination and Food Production.

This article in Nature Climate Change titled Cropping frequency and area response to climate variability can exceed yield response, suggests that previous studies may have underestimated the impact of climate change on the world’s food supply.

In this paper, researchers from a range of research institutions investigate the likely ‘transformational adaptations’ that will be necessary over the next century to maintain agricultural yields in sub-Saharan Africa.

This article in Nature Climate Change argues that the global climate and agriculture research community needs to put increased emphasis on mixed crop-livestock farm systems and their interplay with climate adaptation and mitigation. Written by authors from CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and the International Livestock Research Institute (ILRI), the piece outlines mixed farming systems' value to national development, climate adaptation and resilience building, farmers’ livelihoods and the globe’s food demand.
