As countries advance the new round of Nationally Determined Contributions (NDC 3.0), strengthening the capacity of National Meteorological and Hydrological Services (NMHSs) to deliver robust, decision-ready climate information is more critical than ever.
With support from the CREWS West Africa Project, the World Meteorological Organization convened a French-speaking regional workshop on Climate Scientific Information for NDC 3.0 in Lomé, Togo, hosted by the Agence Nationale de la Météorologie du Togo (ANAMET). The workshop brought together experts and national stakeholders from Burkina Faso, Cameroon, Comoros, Guinea, Madagascar, Rwanda and Togo to enhance their ability to apply climate science in national climate planning and implementation.
“Access to reliable, relevant, and usable climate science information is an indispensable lever for guiding public policies and climate investments.”
— Dr. Tindano Komlan, Secretary-General of the Ministry of Transport of Togo, emphasized the importance of science-based policymaking at the opening ceremony.
Through this CREWS-supported initiative, participating countries strengthened their ability to generate and communicate decision-ready climate information for NDC development and implementation, including through hands-on use of practical tools and methodologies.
The workshop helped countries to:
- Improve climate data quality control and homogeneity assessment for stronger evidence bases
- Calculate and interpret climate indices and trends to inform national climate priorities
- Apply tools such as ClimPACT, Climate Information Portal (CIP) and the Climate Services Dashboard to produce usable outputs
- Strengthen the science–policy interface and the National Frameworks for Climate Services (NFCS) through co-production discussions with sector representatives
- Build NMHS capacity to translate climate science into policy-relevant inputs for NDCs and related plans
Participants rated the workshop highly for practical relevance (4.79/5), reporting clear gains in technical skills and increased confidence in using climate science information to support policies, decisions, and services. They also highlighted the need for continued assistance—particularly on applying climate data to policy planning, strengthening NMHS service delivery, and improving data collection and analysis for both adaptation and mitigation.
By strengthening the capacity of NMHSs to generate, interpret, and communicate robust climate science, CREWS is helping ensure that the new generation of NDCs is grounded in reliable evidence and aligned with national development priorities.
This support enables countries to design more ambitious and implementable adaptation and mitigation actions, enhance transparency and reporting, and strengthen their readiness to access climate finance.
Through continued collaboration, CREWS contributes directly to embedding science-based decision-making at the heart of NDC 3.0 processes across West Africa.
