‘. . . [A]ccording to a new study published in the Proceedings of the National Academy of Sciences, . . . [Africa] will . . . need to dramatically increase its agricultural efficiency. Right now, Africa imports 20% of its cereal needs, despite having a quarter of the world’s arable land. . . . With a population expected to expand by another 1.3 billion people by 2050, Sub-saharan African countries will have to import half of all needed cereals in the next 30 years, if drastic changes to agricultural methods aren’t taken, the study concluded.

New publication warns of rising use of antibiotics and other antimicrobial drugs in farm animals
Delia Grace, a veterinary epidemiologist colleague of Robinson’s at ILRI, was recently asked by the UK Department for International Development (DFID) to write a paper, now under external review, on antimicrobial resistance linked to agriculture. Continue reading
Livestock in poor countries need drugs to stay alive and productive, but how to avoid the rise of ‘super bugs’?
Developing-country livestock keepers need more and better drugs to keep their animals alive and productive, and there are increasing numbers of livestock in the South, where there is increasing use of antimicrobial drugs, and poor livestock keepers will be hurt the most by development in pathogens of antimicrobial resistance. So what’s needed to avoid ‘super bugs’ arising? A new PNAS paper has this to say. Continue reading
Having your cake and eating it too–Working both the production and consumption ends of ‘the meat question’
The Food Climate Research Network (FCRN) site has published (10 Apr 2014) an interesting comment on an interesting paper by Petr Havlík et al., Climate change mitigation through livestock system transitions, published in Feb 2014 in the Proceedings of the National Academy of Sciences (PNAS). Continue reading
The roads not taken: Should 1bn overfed people eat less meat? Or 1bn hungry farmers become more efficient?
The Butcher, by Marc Chagall, 1910 (via Wikipaintings). Should you become vegetarian to help mitigate against global warming? Well, you could, or you might try just eating less meat, if you’re one of some 1 billion people chronically eating too much food. On the other hand, you might try helping some 1 billion small-scale livestock … Continue reading
Yet more evidence that agriculture–particularly livestock agriculture–needs to be part of climate discussions
The farmyard, by Marc Chagall, 1954 (via Wikipaintings). Without big interventions, the future of food security looks bleak. So says an article in One Billion Hungry: Can We Feed the World Website. The clear message from . . . the IPCC Fifth Assessment Report is the urgent need for farmers to adapt to a changing … Continue reading
Research shows vast differences in livestock systems, diets and emissions–FCRN on PNAS paper
Tara Garnet, of the Food Climate Research Network (FCRN), at Oxford University, recently highlighted a paper published recently in the Proceedings of the National Academy of Sciences (PNAS). The paper, Biomass use, production, feed efficiencies, and greenhouse gas emissions from global livestock systems, is written by livestock scientists at the International Livestock Research Institute (ILRI, Kenya) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO, Australia).

What livestock eat (and don’t eat) determines how productive, and efficient, they are–PNAS study
Napier grass (aka ‘elephant grass’), a major feed supplement for dairy cows and other ruminant animals in Kenya (photo credit: Jeff Haskins). Even though research has shown that [greenhouse gas] GHG emissions from the Western world far outweigh those from the developing world, livestock keeping methods in Africa are increasingly becoming a key subject. Europe, … Continue reading
Livestock and global change: Livestock live talk at ILRI on 28 November 2012
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
