The system of drainage channels and natural stream channels in the Albuquerque metropolitan area is a source of concern because of potential local flooding and water-quality problems. Rapid urbanization since 1970 has increased precipitation runoff to these channels, which in many instances return flow to the Rio Grande. As an important element of the City of Albuquerque’s water-resources...

There is a lack of knowledge and understanding of how widespread use of pesticides may affect bees as they move across a diverse agricultural landscape. Studies have shown there are impacts to honey bees due to exposure to pesticides including neonicotinoid insecticides and fungicides, but the effects of these compounds on native pollinators are largely unknown.
