Around 2,700 scientists from 47 countries have signed a letter supporting a scientific paper by Defenders of Wildlife that concludes President Donald Trump's border wall is a threat to biodiversity. "To say the only way we can deal with human security is a wall — as opposed to electronic surveillance at the line or other means that have proven more effective — is a false pretense," said Gary Nabhan, the W.K. Kellogg Chair in Southwest Borderlands Food and Water Security at the UA.
Issues of governance, including the examination of institutional, legal, and decision-making contexts, are a key focus of national and international environmental research at the UA. Faculty work on diverse topics, including water rights; transborder environmental management; collaborative approaches; the interplay of law, biology, and conservation practice; international climate policy; political ecology; international development; and environmental governance on indigenous and tribal lands.
