The Government of St. Kitts and Nevis (SKN) is committed to tackling the adverse impacts of climate change through the implementation of ambitious policies and actions enshrined in its Nationally Determined Contributions (NDCs), in consensus with the Paris Agreement. However, in order to anticipate, prepare for, and respond to hazardous events, trends, or disturbances related to climate variability and change, the Government of St. Kitts and Nevis needs to strengthen existing institutions and systems including addressing the inadequate legislative, regulatory, and operational frameworks and staff capacity as well as deepen private sector and other stakeholders’ involvement in climate action. It is against this background that the Government of St. Kitts and Nevis is proposing this Readiness to strengthen key national institutions that have limited climate change capacity to support the effective development and implementation of climate change interventions as well as raising awareness, and crowding private sector investment for climate action. More specifically, the aim of this readiness is two-fold: (1) to enhance the capacity of the St. Kitts and Nevis Meteorological Services (SKNMS), National Emergency Management Agency (NEMA), Nevis Disaster Management Department (NDMD) and St. Kitts and Nevis Geographic Information System (SKNGIS); and (2) to strengthen private sector involvement in climate action including engagement with the GCF through capacity building and direct support through the development of concept notes.
