The United Nations Office at Nairobi (UNON), on behalf of Climate Technology Centre and Network (CTCN), United Nations Environment Programme (UNEP) invites qualified interested firms to submit Expression of Interest (EOI) to participate in the upcoming solicitation for provision of technical assistance implementation of the Technical Assistance on "Development of a Marine Dynamics database for the Panamanian coasts to assess vulnerability and climate change impacts to sea level rise." United Nations Environment Programme (UNEP) on behalf of the Climate Technology Centre and Network (CTCN) requires the services of an institution to deliver the technical assistance as approved by National Designated Entity from Panama. The overall objective of the Technical Assistance is to develop key tools for risk assessment in Panamanian coasts in order to implement climate change adaptation measures in marine-coastal zones. The main activity of this assistance is the development of high-resolution numerical databases on marine dynamics. Also, this technical assistance will ensure the elaboration of procedural tools for coastal risk assessment based on the data generated, recommendations for nature-based adaptation measures for the coast (nature-based solutions), capacity transfer to the Climate Change Directorate of the Ministry of Environment, and the realization of high impact graphic material on the communities at risk previously identified. Some of the expected outcome, outputs and activities are; • Development of high-resolution numerical data of marine dynamics (Coastal Flood Elevation Points on: (meteorological tide + astronomical tide + waves and mean sea level rise projections) at a resolution of less than 30 km for the Panamanian Atlantic and Pacific coasts at different return periods (10, 15, 50 and 100) and under different emission scenarios. • Methodological tools (procedural guides) for the generation of marine dynamics data and their use in coastal risk assessment • Assessment and recommendation of adaptation measures for the coastal zone with nature- based solutions • Technical capacity building through training for officials of the Climate Change Directorate of the Ministry of Environment. • Development of high impact artwork for communities at risk The complete details of the requirement will be provided in the tender documents that will be issued to bidders after this request for EOI is closed.
