The United Nations Food and Agriculture Organization estimates that the global agricultural sector could potentially reduce and remove 80 to 88 percent of the carbon dioxide that it currently emits. By adopting more-sustainable approaches, small-scale agriculture in developing countries has the potential to contribute 70 percent of agriculture’s global mitigation of climate change. And many of these innovations have the potential to be replicated, adapted, and scaled up for application on larger farms, helping to improve water availability, increase diversity, and improve soil quality, as well as mitigate climate change.

Climate change is making extreme weather much more likely. As the 2012 drought in the USA shows, extreme weather means extreme food prices. Our failure to slash greenhouse gas emissions presents a future of greater food price volatility, with severe consequences for the precarious lives and livelihoods of people living in poverty. This briefing draws on new research commissioned by Oxfam which models the impact of extreme weather – like droughts, floods and heat waves – on the prices of key international staple crops in 2030. It suggests that existing research, which considers the gradual effects of climate change but does not take account of extreme weather, is significantly underestimating the potential implications of climate change for food prices. This research shows how extreme weather events in a single year could bring about price spikes of comparable magnitude to two decades of long-run price rises. It signals the urgent need for a full stress-testing of the global food system in a warming world.
FAO, IFAD, and WFP issued a joint statement on food prices: "In responding to high food prices, the things we must avoid doing are just as important as the things we should do. In particular, countries must avoid panic buying and refrain from imposing export restrictions, which, while temporarily helping some consumers at home, are generally inefficient and make life difficult for everyone else. Above all, however, we must understand that high food prices are a symptom, and not the disease. So while the international community must take early action to prevent excessive price increases, it should also move to act on the root causes behind such surges."
New report by Lars Hein and Rik Leemans. The large majority of biofuels to date is “first-generation” biofuel made from agricultural commodities. All first-generation biofuel production systems require phosphorus (P) fertilization. P is an essential plant nutrient, yet global reserves are finite. We argue that committing scarce P to biofuel production involves a trade-off between climate change mitigation and future food production. We examine biofuel production from seven types of feedstock, and find that biofuels at present consume around 2% of the global inorganic P fertilizer production. For all examined biofuels, with the possible exception of sugarcane, the contribution to P depletion exceeds the contribution to mitigating climate change. The relative benefits of biofuels can be increased through enhanced recycling of P, but high increases in P efficiency are required to balance climate change mitigation and P depletion impacts. We conclude that, with the current production systems, the production of first-generation biofuels compromises food production in the future.
Dar es Salaam — Recent research done by different scientists in Africa has shown that production of important crops especially maize will decrease by 30% for the period of 20 years due to the effect of Climate Change.
The most affected areas according to scientists are in the Southern and Eastern Africa including Tanzania.
That was revealed by the Assistant Director of Environment in the Vice President's Office, Mr Richard Muyungi in Dar es Salaam last week during the agriculture workshop organized by Agriculture Council of Tanzania (ACT).

CGIAR Climate's insight:
While there is broad agreement that the increased focus on climate change and agriculture provides important opportunities, the case studies suggest that it is too early to say whether these opportunities translate into benefits for the poorest and most vulnerable groups and how this should happen in practice.
The failure of the discussions on agriculture in Doha could be used as an opening to better understand what is at stake, and under what conditions concepts such as ‘climate smart agriculture’ could improve the lives of poor and vulnerable farmers.
Young scientists are invited to submit applications for participation in a Networking Conference on Integrated Science.
The ISSC and ICSU, in collaboration with the DFG, are planning to assemble a large group of young researchers with diverse research perspectives to reflect on Food Futures and debate relevant issues as part of a series of conferences on Integrated Science. The aim is to bring together creative multidimensional, interdisciplinary and transdisciplinary perspectives to address such a complex topic like food systems. These early career scientists will ask what are and will be the challenges related to food, now and in the future, and they are expected to devise the next generation of research programmes and projects, looking for a suitable definition and means to reach global sustainability goals.
