The aim of the workshop is to collect information on traditional African processing technologies with emphasis on cassava as a livestock feed, to review the marketing and economics of cassava by-products, to recommend strategies for future research and development on the processing and utilization of cassava as a livestock feed, and to disseminate up-to-date information on cassava.

A study to determine carbon sequestration potentials and soil attributes was conducted in Borana rangelands of southern Ethiopia under communally grazed areas, grazing enclosures (rangelands enclosed for 20 years for dry season grazing) and rangelands managed by prescribed fire for more than five years after fire application. Soil attributes were collected from three soil depths (0–10 cm, 10–20 cm and 20–30 cm) and both aboveground and belowground carbon were estimated in all treatments.

Data from slaughter (LWT) and warm carcass (HCWT) weights and dressing-out percentages (CYD%) of 209 Uda (Sahel) and 26 Djallonke sheep and 105 Djallonke goats were analysed by fitting a least-squares fixed-effects model. The model consisted of the effects of breed and sex on LWT and CYD% and the effects of breed, sex and LWT (as covariate) on HCWT for the sheep data. The effect of sex alone on LWT and CYD% was fitted for the goat data. As for the goat carcass data, HCWT was regressed on LWT for each sex subclass. Effect of breed significantly affected all carcass traits in the sheep.

2012 will be the second year of operation of the CGIAR research program on Climate Change, Agriculture and Food Security (CCAFS). The 2012 business plan lays out the key activities in 2012, situated within the larger strategic framework of CCAFS. At the time of writing, many of the overarching principles for the operation of CGIAR Research Programs (CRPs) are still being produced by the Consortium Office (e.g. monitoring and evaluation strategy), so some of the proposed activities in 2012 may need to be modified as the year unfolds.
