San Juan
Puerto Rico
San Juan is projected to face prolonged drought conditions and elevated risks of arbovirus transmission and malaria in the future. In response, the city implements and plans a range of technology-enabled climate resilience solutions. These include battery storage backup power systems for residential and commercial energy security, and disaster response logistics to enhance transportation capabilities during emergencies. Additionally, resilient building design focuses on planning and construction methods to withstand climate impacts. The health sector benefits from emergency response equipment, mobile units, and sanitation solutions, emphasizing the importance of shelter during crises. Through these current and proposed initiatives, San Juan aims to bolster its resilience to the climate hazards it will experience in the coming years.
