According to 2022 statistics published by the US EPA, enteric fermentation (a digestive pathway that produces gasses in the gut) by cattle accounted for around 3% of total US greenhouse gas emissions when converted to carbon dioxide equivalents. We spoke with Dr. Glenn Duff, from New Mexico State University to learn more about the research he and his team are conducting to measure gas fluxes and emissions from cattle in pursuit of improving efficiency and lowering emissions from this sector.

Agrivoltaics is the combination of agriculture and photovoltaics to create co-benefits across food, energy, and water systems. There is a lot of research being conducted around the benefits and best practices for implementation of agrivoltaics. We spoke with two experts, Dr. Greg Barron-Gafford from the University of Arizona, and Dr. Brandon Bestelmeyer, research leader at the Jornada Experimental Range, to learn more about this fairly new technology.

Flows in the Rio Chama, a tributary of the Rio Grande in northern New Mexico,
have dwindled from drought and rising temperatures as well as diversion for agricultural irrigation. These diminished flows threaten groundwater resources and habitat for endangered plants and animals. Paul Tashjian, Director of Freshwater Conservation with Audubon Southwest, tells us about solutions that have been implemented to alleviate pressures on the Rio Chama and other waterways, bringing back flows for the natural habitat.

We speak with the directors of two non-profit organizations who are turning problems into solutions by getting nutritious food that would normally go to waste back into our food system and into the hands of those who can use it - reducing waste, methane emissions, and fighting food insecurity all at the same time.
