Abstract

The study also highlights the importance of building water and sanitation utilities' technical, operational, policy-based and forward-planning capacities. The present challenge is therefore to devise ways of enhancing the sector's institutional capacities, not only for the application of circular economy principles in water management in the region but also for meeting the challenges associated with the current innovations being driven by artificial intelligence and big data solutions. Doing so will make it possible to leverage activities and projects that will make a direct contribution to the achievement of Sustainable Development Goal 6.
