UN report says 1 million species are in danger of extinction.

Loss of groundwater may accelerate drying trends in the eastern United States, according to research that applied supercomputing to create an in-depth model of how groundwater will respond to warming.

Nonperennial rivers are a major—and growing—part of the global river network. New research and science-based policies are needed to ensure the sustainability of these long-overlooked waterways.

Thanks to an abnormally warm winter, green leaves are sprouting and flower buds are bursting weeks early across the Southeast this year. Spring has sprung prematurely, and depending on the weather during the next two months, this could have detrimental effects on this vegetation.

The University of Arizona’s Annual Greenhouse Crop Production and Engineering Design Short Course is fast approaching. The event takes place March 2-6 at the University of Arizona Controlled Environment Agriculture Center (CEAC), is focused on vegetable production and includes three full days of lectures, one day of hands-on training workshops at CEAC, and an optional commercial greenhouse tour. 

Insect pests can be a grower’s worst enemy, so high-quality, leafy vegetables often depend on insecticides. But to use insecticides cost-effectively, growers must apply only when there is a need. Thus, scouting fields for insect pests plays an important role in making informed management decisions.

Insect pests cause billions of dollars in damage each year and they spread numerous dangerous diseases. If professionals attempting to control pest insect species had information about when those species reached the developmental stages at which they are most vulnerable to control measures, management efforts could be more economical, more effective, and less damaging to nontarget species and the environment.

University of Arizona researchers studied recent extinctions from climate change to estimate the loss of plant and animal species by 2070. Their results suggest that as many as one in three species could face extinction unless warming is reduced.

"Nobody saw it coming this soon," one scientist said. "It's likely the forests won't be coming back as we know them."

Synthetic chemicals that were released into the environment for the first time 80 years ago have been linked to harmful health effects, and more of them are migrating slowly from the soil, according to University of Arizona research.

As the global population is projected to reach nearly 10 billion by the year 2050, the demand to sustainably produce healthy, affordable fruits and vegetables is more pressing than ever.
