Researchers have found that there is a considerable chance that the evolution of pest resistance will outpace human innovation. The idea that weed control is a collective problem requiring collective action emerged relatively recently, said George Frisvold, an agricultural and resource economist at the UA.
The UA is an international leader in climate science, impacts and policy. We use paleoenvironmental techniques to reconstruct past climates and computer models to understand future conditions. We look at how patterns of drought and heatwaves change and cause water shortages, increase wildfire risks, reduce crop production and food security, threaten defense installations, and affect human health and ecosystems. We work with partners to deliver usable climate science and to create effective responses that help people focus on adaptation, resilience, and risk reduction in the face of climate change.
