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.”
In this report commissioned by Center for Global Development, researchers at Chalmers University, Linköping University and Vienna University describe how international trade with agricultural and wood products is an increasingly important driver of tropical deforestation. More than a third of recent deforestation can be tied to production of beef, soy, palm oil and timber.
This blog discusses the June Business Forum meeting organised by the Food Ethics Council which saw businesses and NGOs coming together to consider how industry and government discusses issues of food consumption and choice now, and how this might need to change.
This paper published in PNAS - Proceedings of the National Academy of Sciences of the United States of America - looks at the environmental costs of food production and in particular livestock based food production. The paper is based on annual 2000–2010 data for land, irrigation water, and fertilizer from the USDA, the Department of the Interior, and the Department of Energy.
This report from Centre for Agricultural Strategy at the university of Reading discusses the use of soya in UK livestock feeds. It describes how UK livestock production has become increasingly intensive over the last 20 years with a declining number of livestock farms rearing fewer, more productive animals, which require more nutrient dense feeds, containing a higher proportion of high quality protein. As UK agriculture has been unable to meet all of the demand from for vegetable protein, imported soya bean meal has largely filled the gap.
