Addis Ababa, Ethiopia. African countries have been urged to abandon fragmented policy responses and adopt integrated solutions linking climate, water, energy and food systems to accelerate sustainable development.
The call was made on April 26, 2026 by Mama Keita during the opening of a high-level dialogue bringing together the Opportunity and Issue-Based Coalition 4, the Regional Collaborative Platform for Africa and United Nations Resident Coordinators in Addis Ababa.
Speaking at the United Nations Economic Commission for Africa headquarters, Ms Keita said Africa is facing overlapping crises including climate shocks, rising debt burdens and tightening global financial conditions that are increasingly interconnected and mutually reinforcing.
She said the continent is grappling with a $1.3 trillion annual financing gap for achieving the Sustainable Development Goals (SDGs), part of a global shortfall estimated at $4 trillion.
“Climate shocks are already reducing GDP by between 2 and 5 per cent annually in vulnerable African economies,” she said, warning that disruptions in global maritime routes are also affecting the supply of energy and fertilisers, with direct consequences for food prices and economic stability.
Ms Keita questioned whether Africa can effectively address climate change without tackling water security, or ensure food security without reliable energy, stressing that these sectors are deeply interlinked.
“We can no longer treat these as separate challenges,” she said, adding that silo-based policies and isolated institutional approaches have led to inefficiencies, missed opportunities and slower progress towards the SDGs and Agenda 2063.
She emphasised the need for a Climate–Water–Energy–Food nexus approach, describing it as a shift from managing individual sectors to managing interconnected systems, with the aim of maximising synergies while reducing trade-offs.
Despite emerging examples of integrated solutions across the continent — such as linking water management with renewable energy and improving irrigation systems — Ms Keita said progress remains limited and uneven.
She said the key challenge is not recognising the interlinkages, but ensuring that policies, institutions and financing systems are aligned to respond effectively.
To accelerate progress, Ms Keita outlined three priority areas.
First, she called for stronger policy coherence across sectors, including improved coordination between ministries and the integration of nexus thinking into national development plans.
Second, she urged African countries to scale up innovative financing, including blended finance, green and blue bonds and carbon markets, alongside strengthening domestic resource mobilisation. She noted that tackling illicit financial flows — estimated at $88 billion annually — would be critical in unlocking resources for development.
Third, she stressed the importance of investing in data, science and institutional capacity to support evidence-based decision-making and effective implementation.
“At its core, this is about the choices we make,” she said. “Do we continue with fragmented approaches that deliver incremental progress, or do we embrace integrated solutions that match the scale of our challenges?”
She added that Africa’s future will depend not on how well individual sectors are managed, but on how effectively their interconnections are addressed.
“The nexus is not an option; it is a necessity,” she said.
Ms Keita reaffirmed the commitment of the Economic Commission for Africa to support member states through policy research, technical assistance and regional coordination to translate discussions into concrete action.
