This is a very interesting paper that reviews the literature on the relationship between consumption and GHG  emissions, between population and emissions, and the interactions among all three. It raises doubts that improvements in technology, or shifts in patterns of behaviour (consumption) will be sufficient in addressing GHG emissions unless combined with a greater focus on population growth (scale effects). 

The Global Network of Science Academies (IAP) comprising the world’s 105 science academies, have issued a statement highlighting the relevance of population and consumption to the future of both developed and developing countries and reminds policy-makers preparing for Rio+20 of the need to consider a number of issues.

The Prince of Wales’s Charitable Foundation (PCF) has announced initial funding of £200,000 for a pioneering new project to help British farmers improve their productivity in an environmentally responsible way. The Duchy Originals Future Farming Programme will be delivered by the Soil Association, in partnership with Duchy Originals from Waitrose, The Prince of Wales’s organic food business.

This paper, co written by FCRN mailing list member Kurt Schmidinger argues that the ‘missed potential carbon sink’ - - the carbon sequestering opportunity cost of using land for livestock (and presumably for other agricultural commodities as well as for other activities) needs to be taken into account in calculating the CO2eq emissions arising from any activity. 

In 2009, Rockström et al published a paper in Nature which proposed the concept of nine planetary boundaries, which we must keep within if we are not to suffer potentially catastrophic consequences. More recently Nature has published an interesting opinion piece on the boundaries idea.  

The UK’s Environmental Audit Committee has published its report on Sustainable Food.  Its member MPs conclude that “Government must develop a joined-up strategy to change the UK's unhealthy and environmentally damaging food system, as fears mount about global food security.”

WWF has published its latest biennial report on the state of the planet in time for the Rio+20 summit in June. 

In the mailing on 15 May 2012 we highlighted this paper by Seufert et al, published in Nature, which compared yields in organic and conventional farm systems. The study elicited a great deal of media comment and in response the study’s authors have written this interesting piece which you can read here.

A report published by the National Trust entitled What’s your beef? Compares the cradle-to-farm-gate emissions of ten tenanted National Trust farms, selected as representing a cross section of different beef production systems, including 4 organic, 4 conventional but extensive, and 2 semi intensive farms.
