The United Nations says it’s time to overturn the myth that pesticides can feed the world and come up with better, safer ways of producing our food.

Grasses are better able to withstand drought or high temperatures than many other plants in large part due to changes in their pores, called stomata. Stanford scientists have discovered how grasses produce these altered pores, which could someday lead to crops that can better survive climate change.

Three researchers at the University of Regina have been awarded a provincial research grant to study the role of agricultural dugouts in greenhouse gas capture.

Dr. Kerri Finlay, Dr. Peter Leavitt, Dr. Gavin Simpson of the biology department, along with Dr. Helen Baulch of the University of Saskatchewan, were recently awarded $255,030 from the Saskatchewan Ministry of Agriculture's Agriculture Development Fund.

At University of Toronto Mississauga, a plastic tower sprouts produce including curly starbor kale, buttercrunch and collard greens.

Rising almost six feet off the ground and illuminated by high output fluorescent bulbs, the indoor farm wall grows plants hydroponically – with nutrient solution, instead of soil. The water nourishes the roots, collects in a gutter and then recirculates back to a nutrient tank that feeds back into the hydroponic system.

You are what you eat, as the saying goes, and while good dietary choices boost your own health, they also could improve the health care system and even benefit the planet. Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care. As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.

For decades, phosphorous has accumulated in Wisconsin soils. Though farmers have taken steps to reduce the quantity of the agricultural nutrient applied to and running off their fields, a new study from the University of Wisconsin–Madison reveals that a “legacy” of abundant soil phosphorus in the Yahara watershed of Southern Wisconsin has a large, direct and long-lasting impact on water quality.

Change is never easy. But when it comes to adopting new agricultural practices, some farmers are easier to convince than others.

New research investigating the transition of the Sahara from a lush, green landscape 10,000 years ago to the arid conditions found today, suggests that humans may have played an active role in its desertification. 

The desertification of the Sahara has long been a target for scientists trying to understand climate and ecological tipping points. A new paper published in Frontiers in Earth Science by archeologist Dr. David Wright, from Seoul National University, challenges the conclusions of most studies done to date that point to changes in the Earth's orbit or natural changes in vegetation as the major driving forces.

On a plate, a single banana seems whimsical—yellow and sweet, contained in its own easy-to-open peel. It is a charming breakfast luxury as silly as it is delicious and ever-present. Yet when you eat a banana the flavor on your tongue has complex roots, equal parts sweetness and tragedy.

A Montana State University assistant professor of sustainable food systems who has conducted research all over the world is turning her attention to maple syrup.

Some farmers in the United States and Canada have noticed that the quantity and quality of their maple syrup is changing with climate variability, said Selena Ahmed from MSU's Department of Health and Human Development in the College of Education, Health and Human Development. Ahmed is co-leading a team of researchers who are investigating these observations.
