This paper details the findings of a meta-analysis of published data on the impact of increasing temperatures on the global and regional yield of wheat, rice, maize and soy. 

This article takes a closer look at the telecoupling between China and Brazil based on their soybean trading relationships. Telecoupling is the term used to describe the interconnectedness or coupling of natural and human systems and it indicates that there are complex socioeconomic and environmental interactions over distances.

This article examines how big food companies contend with some of the issues involved in efforts to improve the sustainability of their raw material supply chains. It argues that these large companies often operate in long, complex, and traditionally non-transparent supply chains that make it difficult for them to exert real influence over producers. ‘Big food’ is the description given to the world’s largest and most influential companies in the food and beverages markets.

A key ingredient in junk food is vegetable oil. 60% of this oil is from oil palm and soybean, production of which has been expanding in Southeast Asia and South America, resulting in widespread deforestation and biodiversity loss. In this article, the authors calculate the amount of current deforestation due to vegetable oil consumption (through junk food) and extrapolate vegetable oil demand to predict the deforestation future consumption patterns would cause by 2050.

This paper by researchers in the US and Australia reports the findings of a long-term field-trial-based investigation into the effect of elevated carbon dioxide concentrations (CO2) on soy yield and drought tolerance. Their findings challenge the widely-held belief that crop yield will be increased by elevated CO2 (the so-called CO2 fertilisation effect) both because of increased photosynthetic rate, and because of lower susceptibility to drought: it has long been assumed that in higher CO2 conditions, stomatal conductance will be lower, leading to slower water loss from the leaves, slower water uptake from the roots, and consequently more moisture remaining in the soil for longer, thereby sustaining crops in limited rainfall.

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.

This report by the Food and Agriculture Organisation of the United Nations (FAO) aims to inform decision-making that focuses on reducing impacts on natural capital.

Some scientists have suggested that Africa's wet savannahs could be ideal for growing crops needed to meet the growing demand for food and bioenergy. In this paper however, researchers from Princeton University and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) warn that farmland conversion of these savannahs will come at a much higher cost than previously thought.

Global Forest Coalition and Brighter Green have just released a new report, “Meat from a Landscape Under Threat: Testimonies of the Impacts of Unsustainable Livestock and Soybean Production in Paraguay.”
