To commemorate 30 years of collaboration on arid lands issues, the International Arid Lands Consortium (IALC) is hosting a three-day international conference on arid lands. A key goal of the conference is to underscore the value of the IALC mission
Brown Bag Webinar: International Watersheds Coping with Climate Hazards; Twin-City Solutions at Ambos Nogales and San Diego–Tijuana
Laura M. Norman, Ph.D., Supervisory Research Physical Scientist, US Geological Survey, Western Geographic Science Center
Current climate scenario predictions identify the US-Mexico border as a "hot spot" of climate change, both in relation to increased rainfall intensity and increased temperatures. Twin city areas in the transboundary setting have long histories of management that rely on mutual dependency. Appropriate land use, watershed management, and flood-attenuation plans are critical, yet challenging, especially in cross-border urban areas. Collaboration is imperative for binational sustainable development. This talk summarizes methodologies for predicting watershed response associated with land use and climate change, within a spatial and temporal context. Hydrological modeling will be presented to assess flood vulnerability, simulate the impact of land-use change, and evaluate the impact of potential flood-control interventions. Cross-border geospatial data acquisition and input to models will be described. Results from this research are being used to promote mutualist solutions in Ambos Nogales and San Diego-Tijuana.

Laura Norman is a Supervisory Research Physical Scientist at the US Geological Survey, where she has worked since 1998 on various projects along the US-Mexico border. She is a graduate of the UArizona, where she taught GIS Labs, and is currently an Affiliate who mentors graduate students. Dr. Norman's research uses remotely-sensed imagery and other geospatial data in complex models to predict the fate of non-point source pollutants and identify their sources, consider potential growth scenarios, and document watershed processes. She is well-published on a wide range of topics including environmental health, cross-border policy, regional planning, ecosystem services, and restoration design.
