On December 6 and 7, 2022, a Regional Training Workshop on Gender Mainstreaming in End-to-End Early Warning Systems for Flood Forecasting and Integrated Flood Risk Management has been held in San José (Costa Rica). The workshop was aimed at enhancing the capacities of national and local actors in Costa Rica on gender mainstreaming in ‘end-to-end’ early warning systems for flood forecasting (E2E-EWS-FF) and Integrated Flood and Risk Management (IFRM). Over 20 people participated including officials from meteorological and hydrological offices, Bomberos de Costa Rica, Red Cross Costa Rica and other disaster management offices, gender experts, and community volunteers. The entire workshop was designed and conducted by the WMO and K&I with support from the Instituto Meteorológico Nacional de Costa Rica. Gabriele Quinti (K&I) gave three presentations. The first was on the Monitoring and Evaluation of E2E-EWS-FF and Integrated Flood and Risk Management from a gender perspective; the second covered Gender analysis, Gender responsive planning and Gender responsive budgeting; and the third dealt with relevant instruments, international and regional commitments, and funding on gender mainstreaming in natural risk management.
