    <jats:p>Water resources face an unparalleled confluence of pressures, with agriculture and urban growth as the most relevant human-related stressors. In this context, methodologies using a Nexus framework seem to be suitable to address these challenges. However, the urban sector has been commonly ignored in the Nexus literature. We propose a Nexus framework approach, considering the economic dimensions of the interdependencies and interconnections among agriculture (food production) and the urban sector as water users within a common basin. Then, we assess the responses of both sectors to climatic and demographic stressors. In this setting, the urban sector is represented through an economic water demand at the household level, from which economic welfare is derived. Our results show that the Nexus components here considered (food, water, and welfare) will be negatively affected under the simulated scenarios. However, when these components are decomposed to their particular elements, we found that the less water-intensive sector—the urban sector—will be better off since food production will leave significant amounts of water available. Moreover, when addressing uncertainty related to climate-induced shocks, we could identify the basin resilience threshold. Our approach shows the compatibilities and divergences between food production and the urban sector under the Nexus framework.</jats:p>

    <jats:p>The population of the African continent is significantly increasing which has given rise to societal, economic and environmental changes. This will generate an increase in demand for food, water and energy. Thus, strategies for sustainable management of natural resources need to be adopted urgently in order to match the future needs and to ensure sustainable development on the continent. The Water Energy Food (WEF) nexus is one the avenues for studying the current and future interactions and interdependencies of the WEF sectors under different scenarios and challenges in the effort towards establishing sustainable use of natural resources. Policies around the nexus approach are few or absent at the continental and countrylevels. This paper is a first review on the adoption of the Nexus in two model African countries, Morocco and South Africa. The review compares the water, energy and food sectors and the related national policies, plans and frameworks. The data related to the WEF Nexus revealed key difficulties of availability in both countries. A comparative analysis of the situation in both countries demonstrated differences in policies relating to the WEF Nexus across the sectors: water, energy, and agriculture. Additionally, the paper explores the relevance of technology-assisted frameworks for the WEF nexus and also analyzed risks to agriculture and food security in the context of the reviewed countries.</jats:p>
