Contexte et Justification

In a world increasingly confronted with complex environmental, economic, and social challenges, territories play a central role as catalysts for sustainable development. Although rich in natural resources, they remain particularly vulnerable to growing pressures such as water scarcity, climate change, and rapid population growth.

With the global population projected to exceed 9 billion by 2050, it is crucial to reshape the relationship between territories and nature and to promote innovative and cross-cutting approaches to ensure the resilience of ecosystems and communities.

Applicable across various scales, from local to global, the Nexus WEFE approach offers a transformative framework to address these issues while preserving ecosystems, enabling the optimization of synergies and the design of tailored strategic and scalable solutions, applicable across local, regional, and global levels.

The new edition of the Nexus Forum 2025 aligns with the global momentum to advance the Sustainable Development Goals (SDGs) and Africa’s Agenda 2063, where municipalities, cities, and regions play a central role in addressing interdependent crises related to health, climate, biodiversity, and social inequalities.

This vision is supported by international initiatives such as Race to Resilience, Race to Zero, and the Coalition for Ambitious Multilevel Partnerships (CHAMP), launched during COP28, along with the Baku Climate Unity Pact adopted at COP29.

As the climate crisis intensifies and challenges grow increasingly interconnected, multilelevel cooperation has become imperative to minimize losses and damages, ensure the resilience of territories and accelerate the implementation of global commitments.
