In 2017, hurricanes Irma and Maria were forecast to hit the Dominican Republic. ClimaPlan, a USAID project working with the Dominican municipality of Las Terrenas, recognized that these hurricanes would provide an opportunity to identify the strengths and weaknesses of the city’s climate resilience and adaptation capacity. Fortunately, neither Hurricane Irma nor Maria made landfall in Las Terrenas. However, heavy rainfall, storm surges and high winds damaged infrastructure and businesses and impacted a local economy that is based heavily in tourism.
The project team conducted a Post-Event Assessment of Resilience (PEAR) to document the impacts of the hurricanes and the sensitivity of the people, the power system and other municipal assets to the storms. The PEAR process consists of five steps, beginning with a pre-assessment and ending with a post-event assessment based on field visits and analyses.
ClimaPlan’s PEAR provided several insights, including that electricity distribution is one of the most critical services vulnerable to climate change. Due to its distributed geographic coverage and interconnected nature, electricity distribution is exposed to a broad range of climate stressors. In addition, electrical supply disruptions can have cascading effects that impact all other services.
Las Terrenas’ resourceful approach to turning a negative event into a productive one serves as a model for conducting PEAR and for recognizing the benefits of assessing climate resilience on a local scale.
The PEAR reaffirmed the need for stronger land use planning and enforcement. It also provided specific strategies and recommendations that could be included in municipal and land use plans to increase the resilience of the power sector and other key municipal services. Las Terrenas’ resourceful approach to turning a negative event into a productive one serves as a model for conducting PEAR and for recognizing the benefits of assessing climate resilience on a local scale.
A new paper in the Resources to Advance LEDS Implementation (RALI) Series summarizes the PEAR process in Las Terrenas and how the results can help to improve climate resilience capacity at the city level.
The RALI paper summarizes the findings of the assessment, including an evaluation of the impacts of the hurricanes on power services; a description of the measures taken by the power utility, city and other entities; and identification of key lessons and strategies to increase resilience to future climate events.
The authors would like to thank Dr. Alejandro Moreno for his invaluable work supporting the PEAR assessment of Las Terrenas.
