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 Boksburg (South Africa) from 10 to 12 May 2023. The main objective of the workshop was to strengthen the capacities of national actors in SADC countries on gender mainstreaming in ‘end-to-end’ early warning systems for flood forecasting (E2E-EWS-FF) and Integrated Flood and Risk Management (IFRM). The workshop was attended by 30 participants from Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Zimbabwe and Zambia. Participants represented different stakeholders engaged in flood management, such as representatives of the National Meteorological and Hydrological Services, Disaster Management, and Gender focal points. The entire workshop was designed and conducted by the WMO and K&I with support from the South Africa Weather Service. Daniele Mezzana (K&I) contributed to the implementation of the entire workshop, including group work, capitalization of results into recommendations and lessons learned, and training sessions. Moreover, Claudia Colonnello (K&I) led the session devoted to the presentation on key relevant concepts related to Gender mainstreaming and intersectionality in light of their application in disaster/flood management and E2E-EWS, together with Anne Gondwe and Lineo Rakaibe, gender experts from Malawi and Lesotho. Finally, Gabriele Quinti (K&I) gave two presentations. The first was on the Monitoring and Evaluation of E2E-EWS-FF and IFRM from a gender perspective. The second covered relevant instruments, international and regional commitments, and funding for gender mainstreaming in natural risk management.
