Multi-Stakeholder Dialogue on Climate Risk Assessment and adaptation options prioritization for the Transgabonaise road corridor PPP project
This first Multi-Stakeholder Climate Risk Dialogue will present the preliminary results of the high-resolution climate hazard modelling outcomes, and vulnerability assessment of the road corridor project.
Event description:
As part of the Global Center on Adaptation’s support to the Transgabonaise road corridor project under the Africa Adaptation Acceleration Program (AAAP), a Multi-Stakeholder Climate Risk Dialogue was organized to present results from the climate risk assessment with the African Development Bank, and project partners including the Societe Autiroutiere du Gabon (SAG), and the government of Gabon’s departments of Environment, Weather, and transport.
Historical weather trends, in Gabon, show an increase in mean annual temperatures of +1ºC since 1981, and decrease in mean annual rainfall, at an average rate of 3.8 mm per month per decade since 1960, with regional disparities. The technical assistance provided by the GCA will support an in-depth understanding of future climate hazards under different climate change scenarios, and across the different regions crossed by the 900km road corridor, and led to identify and provide a cost-benefit analysis of adaptation and resilience options to mitigate these current and future climate hazards.

This First Multi-Stakeholder Climate Risk Dialogue will present the preliminary results of the high-resolution climate hazard modelling outcomes, and vulnerability assessment of the road corridor project. Especially, the project stakeholders will discuss the main climate hazards that have been highlighted, including extreme temperatures, extreme precipitation, drought intensity, and how these climate events might impact the assets and transport services. The discussion with local stakeholders will contribute to ensure robustness of the project outcomes.
