Public course in climate change to be offered at UA

The University of Arizona's Humanities Seminars Program is offering a climate change course open to the public to show impacts to Southern Arizona and the world.

UA’s Landmark Commitment to Carbon Neutrality

With a new renewable energy strategy, the University of Arizona aims for more than just sustainability. It has its sights set on radical leadership in the field.

Rethinking Milk: Science Takes On the Dairy Dilemma

Walter Willett, MD, DrPH and David Ludwig, MD, PhD say the science behind dietary recommendations is thin. And they say eating too much dairy may cause harm to both our bodies and the planet.

The “Plant Whisperer” Offers Guidance on Learning the Language of Your Plants

Looking for expert advice on optimizing the environmental conditions in your greenhouse for better plant growth and crop production? The University of Arizona’s Controlled Environment Agriculture Center and the UA College of Agriculture and Life Sciences’ Biosystems Engineering department are hosting a joint seminar featuring Peter van Weel, PhD.

As Groundwater Depletes, Arid American West is Moving East

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.

Science Gets Up to Speed on Dry Rivers

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.

Spring has arrived weeks early in the South. Flowers are blooming, and that could be a problem.

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.

USA National Phenology Network Aids Management of Pest Insects With Life-Stage Forecast Maps

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.

Study: One-Third of Plant and Animal Species Could be Gone in 50 Years

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.

Greenhouse Vegetable Education Abounds in Arizona

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. 

When in Doubt About Your Vegetable Crop, Scout it Out

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.
