To commemorate 30 years of collaboration on arid lands issues, the International Arid Lands Consortium (IALC) will host a three-day international conference, Addressing the Environmental Challenges of Arid Lands. The conference, to be held May 24–26, will celebrate IALC collaborative research and projects and examine current and future challenges in IALC’s regions of focus. A key goal of the conference is to underscore the value of the IALC mission: promoting peace through collaborative research and demonstration projects in the arid lands of the world. The conference will feature keynote presentations and panel discussions on Water and Agriculture, Land and Natural Environment, and Forests and Fire and will emphasize the broader value of collaborative multinational research and problem-solving to address issues that confront the sustainable use and management of arid lands globally. The conference is free to attend with preregistration.
