The San Antonio Region is home to a rapidly growing population with developing energy and agricultural sectors competing for water, land, and financial resources. Despite the tight interconnectedness between water, energy, and food challenges, little is known about the levels of communication and coordination among the various officials responsible for making the decisions that affect the management and planning of the three resource systems. This presentation highlights various methods for stakeholder engagement carried out as part of the NSF INFEWS project in the region. It highlights key identified barriers for cross-sectoral communication and offers reflections on lessons learned. **Resource Use**: *License*: [CC-BY](https://creativecommons.org/licenses/by/4.0/legalcode) *Citation*: Daher, B.
