Project Overview

Climate change and associated variability in water resources pose serious challenges for water managers in the southwestern United States and northwestern Mexico. Urban areas confront the future challenges of rapid growth and intensified water demand related to socioeconomic changes and climate-related uncertainties, such as droughts, flooding, and the potential of reduced water supply.

Rapid growth in these areas has increased the vulnerability of urban water users to climatic changes. Looking toward a 20-year horizon, this project has focused on research to develop adaptive long-term planning for water management in four urban "hotspots" in the North American monsoon-affected corridor of Arizona and Sonora:
Tucson, Hermosillo,  Ambos Nogales (Nogales, Arizona and Nogales, Sonora), and Puerto Peñasco.

This project, supported by the National Oceanic and Atmospheric Administration’s Sectoral Applications Research Program (NOAA-SARP), examined stakeholder-researcher engagement to develop regionalized adaptive water management strategies to reduce urban and rural vulnerabilities and build resilience. Working closely with urban water managers and civil preparedness planners in the Arizona-Sonora region, this project developed vulnerability assessments and site-specific adaptive management scenarios at the 5-, 10-, and 20-year horizons for the identified urban areas. In addition to support from NOAA-SARP, the project benefited from support and collaboration from the Climate Assessment for the Southwest Program (CLIMAS) and the Inter-American Institute for Global Change Research (IAI).

Goal and Activities 

Goals 

 Institutionalize the use of climate information by decision-makers in southern Arizona and northwest Mexico to foster longer-term adaptive planning and increase resiliency under conditions of uncertainty.
 Address the impacts of climate variability and climate change in vulnerable urban and rural areas.
Regionalize climate science production and utilization by water managers and other stakeholders through the development and field-testing of a binational, bilingual climate outlook summary.

Activities 

 Use climate diagnostic information to identify and assess societal vulnerabilities posed.
 Socioeconomic and demographic change, climate variability and change, and emerging water demand uncertainties.
 Assess the institutional and policy implications of identified vulnerabilities.
 Work with stakeholders to develop adaptive management strategies for mid-long term scenarios.
