This book preserves and scientifically interprets the African foreknowledge on water resources management. It offers insight into the relevance of the traditional knowledge and practices to modern approaches on sustainable water management. The African continent has partially preserved its natural habitat for centuries. In this book, this knowledge is combined with the current scientific understanding. The traditional practices are categorized as: i) water harvesting, ii) water transportation, iii) water storage and conservation, iv) water treatments, v) myths and folk stories about water management or conservation, vi) water resource management systems, and vii) soil-water-forest conservation/management systems sub-topics. The findings presented here are in line with SDG 6, which aims at ensuring availability and sustainable management of water and sanitation for all by the year 2030.
