Water is a crucial resource; and its quality and availability constitute powerful determinants of sustainable health, economic growth and social development. Globally, water is a major challenge and there is need to explore the prime place of water towards the successful delivery of United Nation’s Sustainable Development Goals in sub-Saharan Africa.

Tackling today’s water-related challenges and expanding relevant frontiers demand a scientific approach and a collaborative convergence of the humanities, social sciences, and natural sciences. This topical collection on water sustainability in Africa is an interdisciplinary assemblage of research, responses, conversations, perspectives, and creative approaches to the water, health and climate nexus. It offers new ideas, African viewpoints, indigenous knowledge and local content in dealing with water challenges.

Keywords: Water, sanitation and hygiene (WASH); Drinking water treatment options; Aquatic environments and One Health; The arts and humanities for water and health; Water education, literacy and awareness; Water governance and resource management; Risks, vulnerability and resilience assessment; Water, Climate change and food security; Water, women and gender concerns; Wastewater treatment and bioenergy

Water scarcity and lack of sustainable water and groundwater are global issues nowadays. There is a growing demand throughout the world for sustainable watershed development, management, and planning. The demand is more significant in the rain-fed and drought-prone areas of earth surface, where watershed management is poorer and groundwater is limited. The main Attention of this proposal is to improve the groundwater, watershed management, suggesting the water conservation structures, water budgets, identify the groundwater potential zone, surface runoff, land use influence on ground and surface water and use of remote sensing and GIS. For the preparation and implementation of various projects conservation majors are involved and hence, manage and improve the watershed function. In this proposal, for the planning of groundwater development many accurate, latest and fast results technologies can be summarized. These technologies are Modflow software, machine learning, artificial intelligence, and geospatial techniques.

This proposal will discuss, land use/ land cover, rainfall, groundwater conservation zone, water conservation structures, groundwater flow, watershed development, ground and surface water budgets and development of water resources. This proposal mainly focused on the recent technology and application area are of groundwater flow modeling software, wavelets techniques, remote sensing, GIS, methods in rainfall trends, water conservation techniques in the field of watershed development, groundwater planning, changes of land use, monitoring and modeling of groundwater and aquifer mapping, hydrological modeling, and sustainable land management.

Keywords: watershed management; water conservation methods and structures; ground and surface water budgets; groundwater modeling; aquifer modeling; remote sensing and GIS.

This Collection supports and amplifies research related to SDG 6.
