The WRRC 2019 Conference, "Arizona Runs on Water: Scarcity, Challenges, and Community-based Solutions", will include a new participatory element. We are soliciting case studies that describe a community water challenge/solution, including the barriers or opportunities that have hindered or helped the community work toward a solution. You can submit your case-study through a simple online form where you can indicate your interest in presenting a three-minute lightning talk during the conference session. You don't have to attend the conference to contribute. All submissions will be included in a compendium of case studies as a follow-up to the conference. Submissions are due by close of business today, Friday, January 11, to be eligible for presenting at the conference. Lunch speakers must be registered for the conference, which will take place on February 1, 2019 (8 am - 2 pm), at the Black Canyon Conference Center, 9440 N. 25th Ave., Phoenix, Arizona.
