PJ Santa (Pedro J. Santa Rivera)
Principal Consultant in Watershed-Wide Adaptation, Blue-Green Infrastructure, and Nature-Based Solutions
PJ Santa is an expert in watershed-wide adaptation, blue-green infrastructure, and nature-based solutions, pioneering cutting-edge models for urban hydrology, environmental stewardship, and climate resilience within the emerging "blue-green data economy of the future". His transdisciplinary approach integrates hydrology, ecology, urban systems, climate adaptation, and technology applications, advancing decentralized, community-driven, and data-informed strategies to build climate-resilient watersheds and adaptive cities.
As Strategic Director and Principal Consultant at Urban Hydrologics LLC, PJ Santa is at the forefront of developing the Urban Hydrologics Virtual Twin and the Strategic Adaptation Framework, leveraging key environmental variables—water quantity, water quality, community, and ecology—to create holistic, scalable solutions for tropical watersheds. His vision is to empower watershed residents as active stewards of decentralized blue-green infrastructure, ensuring climate adaptation efforts drive economic resilience, restore ecological corridors, enhance open spaces, and improve public health outcomes through climate action.
PJ Santa’s expertise in strategic consulting for watershed-wide adaptation began in 2011 in Singapore, where he spent over a decade leading island-wide climate adaptation initiatives that optimized urban drainage networks, integrated blue-green infrastructure, enhanced connectivity, and developed climate-resilient smart urban districts. His work has shaped policy frameworks, technical guidelines, handbooks, cost-benefit analyses, and masterplans for tropical cities and islands, advancing urban hydrology and decentralized blue-green infrastructure solutions.
With offices in Singapore and San Juan, Puerto Rico, PJ Santa continues to lead transformative projects in urban hydrology, climate technology, and resilient infrastructure, integrating nature-based solutions across inland and coastal environments. Puerto Rico serves as a vital case study, showcasing how tropical islands can harness blue-green infrastructure, digital climate metrics, and policy innovation to scale climate adaptation solutions globally.
