The authors behind this study say that climate change has substantially increased the prospect that crop production will fail to keep up with rising demand in the next 20 years.

Yet another paper adding to the growing body of evidence that productionist approaches to addressing food security challenges are unlikely to be sufficient (at least not without unacceptable environmental cost).  Shifts towards more plant based diets and measures to address food waste are also needed.

Researchers at the University of Gothenburg, Sweden, have published a study in the journal Global Change Biology claiming that rising levels of atmospheric carbon dioxide have a negative impact on the protein content of wheat grain and thus its nutritional quality.

The Bioenergy Strategy commits the UK Government to further work to investigate the merits of temporarily flexing or otherwise relaxing biofuels mandates at times of agricultural price pressures. The current paper presents work by Defra analysts to explore some of the potential implications of this idea.   

A life cycle comparison between processed ready meals and their home-made equivalent were published in a special edition of the journal Ambio (Ambio: A Journal of the Human Environment, vol. xxxiv number 4-5 June 2005). The conclusions are that there's not a lot to choose between the two. The home cooked meal used slightly less energy but generated slightly more GHG emissions (a result of different waste disposal assumptions).
