This project aims to strengthen skills and synergies in a regional centre of expertise in international development, located in the city of Clermont-Ferrand (France), and its international outreach. This involves funding training activities and research capacity building for stakeholders from the Global South (executives, young researchers, etc.), as well as research activities on development.
Context
Clermont-Ferrand is a hub of expertise in development economics recognized at the French and international level, thanks to the research activities of the Foundation for Studies and Research on International Development (FERDI). Training courses aimed at executives and future decision-makers in the countries in the Global South, provided in particular by the Centre for International Development Studies and Research (CERDI) since 1976, also contribute to this recognition.
The presence of a branch of the Global Development Network (GDN) will now strengthen this hub. This international organization's mission is to strengthen research capacities in Global South countries wishing to benefit from the city's dynamic context.
Through AFD, the French State supports the research and training activities of the Clermont International Development Hub and the establishment of the Clermont-Ferrand branch of GDN within the framework of a single project. This project aims to strengthen the ecosystem of local expertise and to develop synergies between the actors concerned for the benefit of their partners in the Global South.
Goal
This project has three complementary objectives:
- Support for the creation in Clermont-Ferrand of a branch office of the GDN, to enable the network to continue from France its flagship activities (such as its annual conference and the Global Dev blog), as well as to launch an ambitious programme to simultaneously fund research production and capacity building of African research institutions;
- Support for FERDI’s research activities, to enable the foundation to gain visibility and influence on sustainable development issues;
- Strengthening of FERDI’s training activities in partnership with the University of Clermont-Auvergne, including the Master’s degree in “Project Management for Development” (MODEV), which specifically targets executives in countries in the Global South, and setting up additional training activities (development of short and/or distance courses, support for doctoral courses in the South).
Results
The expected impacts of the project are:
- For the actors of the Clermont Hub: strengthening the influence and outreach of the Clermont pole and its actors, allowing them to become a reference on development issues in national and international debates.
- For the partners of the Clermont hub in the Global South, and in particular in French-speaking Africa:
• Improving the skills of managers who receive training (women and men) in the management of development policies and projects;
• Strengthening the research capacities of researchers and partner institutions in the Global South on sustainable development issues, as well as their capacity to participate in public debate;
• Development and/or consolidation of networks of researchers and learners in beneficiary countries;
• Improved public policy dialogue, so that development policy-making in AFD’s partner countries can benefit from the insights of locally based research.

When Research Informs Public Action: A Toolkit to Rethink Monitoring and Evaluation
Completed
2020 - 2025
The coastline of the Gulf of Guinea is lowly elevated and particularly vulnerable to sea level rise triggered by climate change. However, in some places, another important factor has to be taken into account to correctly assess the exposure of inhabitants and ecosystems: the gradual lowering of the land surface. The objective of this research program is to quantify this phenomenon and to understand drivers and processes, especially in coastal megacities and deltas.
Context
The densely populated and lowly elevated coastline of the Gulf of Guina is particularly exposed to coastal erosion and sea-level rise. The entire coastline is currently experiencing alarming erosion rates, ranging from 1 to 15 meter per year between Côte d’Ivoire and Nigeria, mostly because of human activities. The problem is well studied and various programs aim to put in place coastal protection measures. By contrast mid- and long-term vulnerability to sea-level rise triggered by climate change has received less attention in this region.
In addition, to assess the various risks induced by sea-level rise, it is also necessary to consider land surface movements. The gradual lowering of the land surface in some places is called subsidence. The phenomenon is widespread at the global scale, especially in coastal megacities and deltas: 51 to 71% of present-day relative sea-level rise experienced by people worldwide is actually caused by subsidence. The rate can reach several centimeters per year in some places, however coastal subsidence is globally critically under-quantified, and the Gulf of Guinea region is no exception to this.
Objectives
This research program aims to fill the lacune in knowledge on coastal land subsidence and relative sea-level rise along the Gulf of Guinea. It will provide useful space-borne quantifications of current coastal subsidence rates, assess the driving forces of land subsidence and provide first projections of potential future subsidence using numerical models.
Impact will further be created by collaborating with local institutes, connecting to other projects and disseminating findings, data and tools to local stakeholders.
One of the long-term objectives is also to create awareness and agenda setting of this issue of relative sea-level rise in the region, in order to support sustainable development or adaptation projects in coastal areas and policymaking in the region.
Method
The first working group will assess current subsidence rates for the whole coastline, using satellite data to monitor vertical land movement over several years. The results will be combined to satellite elevation data to provide a first assessment of the areas that could be flooded in future decades.
The second working group will focus on the city of Lagos and surroundings, to provide an in-depth analysis of subsidence and to understand drivers and processes. The research team will build a process-based numerical model of subsidence to provide projections of future subsidence rates according to different scenarios.
Then, the methods developed for Lagos will also be applied to 3 or 4 other areas, coastal megacities or deltas, identified as “hotspots” for relative sea-level rise by the first working group.
Knowledge exchange events (seminars and workshops) will also be regularly organized, to disseminate research findings and build a regional community of interest on subsidence and relative sea-level rise.
Results
Results will be shared through scientific papers, technical reports, on-line databases and policy briefs. They will provide valuable information for policymakers and coastal (infrastructural) development projects potentially impacted by relative sea-level rise. In particular, results will help to better calibrate coastal adaptation measures and may also identify areas where the efficiency of natural coastal defences could fail in the future. Understanding the drivers of subsidence will also help to identify potential mitigation measures. The project will also foster public policy dialogue on coastal vulnerability, to favor adaptation projects.
In November 2023, a Research Conversations webinar provided an overview of the current state of knowledge on these issues in the region. The replay is available below:
The ENGULF project team then organized a webinar series to present the main findings of the ENGULF project. The replays are available below.
