The International Livestock Research Institute and the World Bank hosted a meeting on livestock in Nairobi on the 12-13 March.  Some of the presentations may be of interest, in particular:

This paper firstly considers the argument that intensification in the Brazililan livestock sector can help reduce land use change pressures (the ‘land sparing’ argument). It then uses an economic model-based analysis to make the point that intensification in the Brazilian livestock sector to increase productivity on a given area of land will only halt deforestation if it is accompanied by policies to alter the fact that extensifive cattle rearing is still marginally profitable.

This discussion paper questions the idea that ‘greener’ economic growth can achieve the reductions in GHG emissions that are necessary – a point that was also powerfully made by Tim Jackson in his 2009  book Prosperity without Growth: Economics for a finite planet.

This article in the Copenhagen Post covers reactions to the Danish government’s proposal to tax sugar  in a manner similar to last year’s introduction of a saturated fat tax.

This study calculates and maps humanity’s green, blue and grey water footprint at a high spatial resolution. 

Aljazeera video series earthrise takes an upbeat look at ecological, scientific, technological and design projects all around the world, from a farm in Australia growing low impact crops using sea water and solar power, to an ingenious project that has dramatically cut rhino poaching on a South African game reserve.

The CCAFS (Climate Change, Agriculture and Food Security) programme have published a new report that looks at the role and effectiveness of private sector CSR activities in the agricultural sector.

The Scottish Aquaculture Research Forum has published a study on Scottish produced suspended mussels and intertidal oysters. The study considered the cradle-to-gate impacts of the shellfish, from spat collection in the case of mussels, and hatching in the case of oysters, through  growing, harvesting, depuration, and packing ready for dispatch.  To illustrate the carbon impacts of the full life cycle, a scenario is included that,  based on various assumptions, illustrates the potential impacts of distribution, retail, consumption and disposal of the shells. 

This article in Science Daily is based on materials prepared by the French Institut de Recherche pour le Développement (IRD)  It argues that Brazil’s reliance on agricultural exports to drive economic growth is environmentally unsustainable and highlights the link between deforestation for cattle grazing, soy production on cleared land which pushes cattle further into the forest, and the sale of high-value timber.  The article states that government controls introduced from the year 2000 have scaled down deforestation from around 20,000 to 6,000 km² per year, but the threat of an increase in world demand is always just over the horizon, with implications for further deforestation.
