Globally, the demand for meat products is growing at 1.8% per year due to increasing populations, economic growth and rapid urbanization. Agropastoral and pastoral systems cover 45% of the earth’s usable surface and supply 9% of global meat production, while mixed crop-livestock farming systems produce 54% of the total meat and 90% of the milk … Continue reading »

Got Milk? Dairy found essential to prehistoric development in Africa–new research
Petroglyphs and pictographs in the Jebel Acacus, Libyan Sahara (photo on Flickr by Carsten ten Brink / 10b travelling). This month’s publication of a scientific article on new evidence of livestock herding in prehistoric Africa is stirring interest. ScienceDaily, for example, reports the following: Chemical analysis of pottery reveals first dairying in Saharan Africa nearly 7,000 years … Continue reading »
Livestock genes identified to unlock protection from animal plagues
West Africa’s ancient (humpless) N’Dama cattle (white) are genetically resistant to the disease trypanosomosis while East Africa’s Improved Boran (humped) cattle are susceptible to this tsetse-transmitted disease (photo credit ILRI/Elsworth). Xinhuanet, the Chinese Xinhua News Agency online service, reports on an international research team that used a new combination of approaches to find two genes … Continue reading »

Aid Netherlands has picked up news of a paper published last month in a leading scientific journal about a breakthrough in determining the genes responsible for controlling a tsetse fly-transmitted disease of livestock that has devastated Africa, and held back farming on the … Continue reading »
‘New science’ is ‘networked science’: The data-crunching workflows and pipelines behind a recent gene discovery
The single-celled parasite Trypanosoma brucei (appearing in blue), which causes sleeping sickness in humans and trypanosomiasis in livestock, amongst the red blood cells of its mammalian host (photo credit: Parasite Museum website). Having been domesticated in Africa some 8,000 or more years ago, the N’Dama, the most ancient of African cattle breeds, has had time to … Continue reading »
Study finds gene clues to African cattle disease
Reuters reports the following yesterday. ‘Scientists studying the tsetse fly-borne disease “sleeping sickness” and a devastating version found in cattle say they have found two genes that may in future help rescue the livelihoods of millions of farmers in Africa. ‘In a study in the Proceedings of the National Academy of Sciences (PNAS) journal on … Continue reading »
Intensify–not expand–tropical croplands where you can, new study recommends
A small-scale mixed crop-and-livestock farmer in Oyo State, Nigeria (photo credit: ILRI/Mann). From the University of Minnesota come this news yesterday of a new scientific paper showing the environmental importance of intensifying rather than expanding tropical farmlands to feed the world’s growing human populations and to provide poor people with livelihoods. ‘According to a study … Continue reading »
Livestock: Lengthening the shadow?
The environmental impact of meat is something of a well-done dish. Rajendra Pachauri, head of the Intergovernmental Panel on Climate Change (IPCC), and Sir Paul McCartney are just two of the public figures who have called on us all to eat less meat in order to curb the rate at which the world warms. The … Continue reading »
Scientists warn of livestock greenhouse gas boom
Soaring international production of livestock could release enough carbon into the atmosphere by 2050 to single-handedly exceed ‘safe’ levels of climate change, says a study. Scientists combined figures for livestock production in 2000 with Food and Agriculture Organization projections for population growth and meat consumption by 2050. They found that the livestock sector’s emissions alone … Continue reading »
Just who should reduce their consumption of meat, milk and eggs to reduce livestock greenhouse gas emissions?
Milk from a dairy cow kept by a household in the highland farming community of Embu, Kenya, generates a regular income that helps this family pay for their children’s school fees (photo by CGIAR/Mann). Agricultural systems analyst Mario Herrero, of the International Livestock Research Institute (ILRI), takes issue this week with a paper published 4 … Continue reading »
