On July 8, 2025, in Dakar, Senegal, the African Development Bank (AfDB) convened a pivotal workshop to advance the Water-Energy-Food-Ecosystem (WEF-E) Nexus Initiative—an effort to break down sectoral silos and reimagine development through systems thinking. With Africa’s population on track to reach 2.6 billion by 2050, participants agreed: siloed planning is a luxury the continent can no longer afford. The gathering brought together ministers, regional bodies, technical experts, and financiers to test an investment framework that aims to channel blended finance into cross-sector projects addressing multiple development needs at once.
The core ambition of the WEF-E Nexus Initiative is to treat water, energy, food, and ecosystems not as four separate challenges, but as one interdependent system. The Bank used the Dakar meeting to refine a ten-year pipeline of investment-ready projects supported by an inclusive governance model. Among those in attendance were representatives from regional economic communities, river-basin organizations, development finance institutions, national planners, and private investors.
One of the clearest takeaways from the meeting was the call to “break the silos.” Implementing the WEF-E nexus, participants stressed, requires political will, institutional coordination, and access to innovative finance mechanisms. Delegates also rallied behind the idea of treating water infrastructure as a regional public good that can catalyze intra-African trade and prosperity. Population growth featured heavily in the discussions—Africa is set to add more than one billion people in just 25 years, with direct consequences for demand on water, energy, and food systems.
AfDB Director Mtchera Johannes Chirwa highlighted the role of special initiatives like the WEF-E Nexus in bringing together diverse stakeholders to amplify development impact. Researchers and policymakers alike acknowledged that Africa is underperforming on global WEF-E indicators, largely due to fragmented governance and water insecurity. Unless integrated approaches are adopted, the performance gap is expected to widen in the face of climate change and urban expansion.

To tackle these structural challenges, the AfDB’s investment framework will bundle water, energy, and agriculture assets into cohesive, bankable projects. This approach aligns with the Bank’s broader electrification campaign—Mission 300—and its commitments made at the Dakar-2 Summit on food systems. Financing strategies include the use of concessional guarantees and results-based grants to attract commercial capital and reduce risk, helping bridge Africa’s estimated $100 billion annual infrastructure funding gap.
Encouragingly, signs of regional momentum are emerging. In mid-July 2025, the East Africa FEW Conference in Mbeya, Tanzania, brought together academics and engineers to explore technical solutions to water-energy-food security. Earlier in the year, the UN Office for Sustainable Development and the Stockholm Environment Institute (SEI) held a hybrid workshop in Addis Ababa focused on governance tools and systems modelling for better policy alignment. Meanwhile, on the ground in Kenya’s Ewaso Ng’iro Basin, a pilot project led by SEI Africa is demonstrating how ecosystem-based adaptation can be integrated into WEF planning.
Looking ahead, several next steps will determine the pace and effectiveness of the Nexus Initiative. Countries are being urged to integrate nexus goals into their national development strategies and budget cycles. The AfDB plans to finalize a list of cross-sector, shovel-ready projects by the end of 2025, based on the feedback gathered in Dakar. Public awareness and capacity building efforts are also ramping up, with the Bank using social media platforms like Facebook and X to keep stakeholders engaged. In parallel, new WEF-E indicators are being developed to help countries monitor trade-offs and co-benefits, with the goal of improving Africa’s performance on global sustainability indices.
The bottom line for sustainability watchers is clear: the AfDB is moving from theory to action. If its WEF-E investment framework succeeds, it could unlock billions in financing, reduce duplication of development efforts, and build the resilience of African communities facing mounting resource pressures. In a future where every drop of water, watt of energy, and kilogram of food must count, integrated planning is not just strategic—it’s essential.
