In 2020, the Global Water Partnership-Caribbean (GWP-C) began supporting the Government of the Dominican Republic (DR) to develop estimates of increased risk of flooding and landslides due to rainfall projections under climate change scenarios. This technical study was completed in the last quarter of 2020. It is one of a series of activities and outputs by GWP-C to inform the preparation of the country’s submission for the second round of Nationally Determined Contributions (NDCs) and is part of the Climate Action Enhancement Package (CAEP) from the NDC Partnership.
