Plant science the answer to food security?

Among the biggest challenges is a growing global population expected to reach nearly 10 billion by 2050, which will need to be fed without degrading more natural resources. Other challenges include regions around the world suffering from increased salinity in soil, water supplies tainted with fertilizer, declining crop yields due to plant disease, and intensifying droughts. The agricultural powerhouse of California, for instance — responsible for producing about half of the United States’ vegetables, fruits and nuts — has entered the fourth year of a historic drought with no relief in sight. Danforth scientists are developing crops to withstand these environmental stressors as we brace for the impacts of climate change.
“Human-induced climate change is here and now. It’s not just something we need to think about for our grandchildren,” says Kathy Jacobs at the second National Adaptation Forum in St. Louis, where she joined more than 800 representatives from the private and public sector in May.
Jacobs directs the Center for Climate Adaptation Science and Solutions at the University of Arizona and coauthored the 2014 National Climate Assessment, which evaluates and summarizes the impacts of climate change on the United States. When the report — the third of its kind since the passage of the Global Change Research Act of 1990, which mandated the development of a comprehensive US climate change research program — came out last May, the consensus among its roughly 300 authors was clear: Don’t waste any more time on denial. The science of climate change is well understood and, increasingly so, its impacts.
