With climate change posing a threat to food production around the world, scientists are developing a form of virtual time travel that can offer farmers in many countries a glimpse of their future by identifying regions where growing conditions today match those that will exist 20 years from now, according to a new report from the CGIAR Research Program on Climate Change, Agriculture and Food Security.

Climate change could significantly alter water flows in major river basins in Africa, presenting a new barrier to nascent efforts to better manage water for food production and to resolve potential cross-border water conflicts all over southern Africa, according to research findings presented at this week's Third International Forum on Water and Food in Tshwane, South Africa.

A team of Michigan State University researchers secured a $700,000 grant to help farmers in Zambia and Kenya overcome the challenges faced from changes in climate. The project, which will link climate change to coping strategies and impacts on food production, food security and incomes for farm families in those areas, is funded by the US Agency for International Development Bureau for Food Security, Office of Agriculture, Research and Transformation.

 | Plants may have the genetic flexibility to respond to climate change. In experiments with the common European plant Arabidopsis thaliana, a team of researchers led by Brown University scientists learned that climate is the agent that determines the suite of genes that gives the plant the best chance of surviving and reproducing throughout its natural range. The finding may unlock the molecular basis for other plants' adaptability to climate change. Results appear in Science. ...> Full Article |
Responding to appeals from African leaders for new tools to deal with the effects of climate change on food production, the CGIAR Research Program on Climate Change, Agriculture and Food Security has released a series of studies focused on "climate proofing" crops critical to food security in the developing world.

Climate and growing seasons are changing, and a Michigan State University professor is helping farmers adapt to those changes. Ask farmers if they believe in climate change and political views tend to temper their responses. However, if asked if they've noticed changes in how weather has affected their work, farmers will cite numerous trends, said Jeff Andresen, MSU associate professor of geography and Michigan's state climatologist.

The Basque Institute for Agricultural Research and Development, Neiker-Tecnalia, is leading an international project with the goal of developing new potato varieties which are tolerant to the effects of climate change, as well as to identify already existing cultivars that are capable to resist these effects.

 | Climate change is likely to make plants more vulnerable to infectious disease, which will threaten crop yield and impact on the price and availability of food. Dr Adrian Newton, presenting his work at the Society for General Microbiology's Spring Conference in Harrogate, explains how exploiting diversity in crops is the best option to improve food security in a changing climate. ...> Full Article |
 | Chemical changes in tree leaves subjected to warmer, drier conditions that could result from climate change may reduce the availability of soil nutrients, according to a Purdue University study. ...> Full Article |
 | The effects of climate change and population growth on agricultural land area vary from region to region, according to a new study by University of Illinois researchers. Regions with relative high latitudes -- China, Russia and the US -- could see a significant increase in arable land in coming years, but Africa, Europe and India and South America could lose land area. ...> Full Article |
Improving land management and farming practices in Australia could have an effect on global climate change, according to a study published in the International Journal of Water.

 | Sensitive to drought due to its high water requirement, rice is particularly vulnerable to how global climate change is altering the frequency and magnitude of floods and droughts. Now plant scientists at the University of California, Riverside, have made a discovery that can greatly benefit rice growers and consumers everywhere. The researchers have demonstrated in the lab and greenhouse that rice that is flood tolerant is also better able to recover from a drought. ...> Full Article |
Wheat growers in the Southwest have a better idea about how to adjust to climate change in the decades ahead, thanks to US Department of Agriculture scientists in Arizona.

The ability to stay ahead of climate change is vital to the agricultural industry -- crops thrive or diminish based upon climate variables. Research collaboration between the University of Idaho, Washington State University and Oregon State University -- all western land-grant institutions -- aims to help agriculture anticipate climate change and protect and increase yields. The research, led by Idaho, is funded by a $20 million grant from the USDA.

 | Large-scale crop failures like the one that caused the recent Russian wheat crisis are likely to become more common under climate change due to an increased frequency of extreme weather events, a new study shows. ...> Full Article |
Scientists synthesize information about interactions of climate change, plant pathogens and forests in a new report for managers titled "Review of Literature on Climate Change and Forest Diseases of Western North America." This project includes an online "Annotated Bibliography of Climate and Forest Diseases of Western North America." Citations and summaries for over 1000 records of journal articles and working papers on forest pathogens and climate are retrievable by author, topic, species or geographic area.

Winter chill, a vital climatic trigger for many tree crops, is likely to decrease by more than 50 percent during this century as global climate warms, making California no longer suitable for growing many fruit and nut crops, according to a team of researchers from the University of California, Davis, and the University of Washington. The study will appear July 22 in the online journal PLoS ONE.
