Drought poses a significant challenge to resource managers in the Caribbean. In Puerto Rico and the Virgin Islands, limited water storage capacity, aging water infrastructure and primarily rain-dependent agriculture make the territories particularly vulnerable to drought. While many entities work to monitor, research and communicate about drought, no overarching framework previously existed to facilitate knowledge-sharing between them, and drought-related initiatives tended to be siloed by entity, with little synergy among efforts. To better leverage existing knowledge and initiatives in the region, the USDA Caribbean Climate Hub worked with partners from the National Drought Mitigation Center, NOAA National Integrated Drought Information System, NOAA National Weather Service and other local partners to initiate the Caribbean Drought Learning Network (CDLN). The recently established CDLN links climate researchers, service providers, advisors, managers, and producers in a peer-to-peer network to strengthen collaboration and communication in drought research and management.
