A review summarizes how machine learning has been applied over the past decade to groundwater availability research, focusing on groundwater level prediction and groundwater potential mapping studies in Africa. The work compiles relevant papers, categorizes the machine learning algorithms, and analyzes the geological and climate inputs by frequency of use. Results indicate fuzzy-based approaches are most common, hydrology/hydrogeology variables dominate level prediction, geology is most studied for mapping, and precipitation receives the greatest climate attention. The review concludes that expanded research is needed and highlights machine learning’s value for water-resource management and decision-making.","Review  \nReview of machine learning algorithms used in groundwater availability studies in Africa: analysis of geological and climate input variables  \nHaoulata Touré1 · Cyril D.

However, the continent faces challenges with groundwater scarcity due to factors like population growth, climate change, and over-exploitation. Over the past ten years, machine learning has been increasingly and successfully used in groundwater availability studies across the world. This review paper explores the application of machine learning techniques in groundwater availability studies including groundwater level prediction and groundwater potential mapping studies by focusing on some of the studies conducted in Africa. The methodology involved downloading relevant papers, identifying and categorizing the machine learning algorithms employed, and quantifying their use. Geological and climatic variables were also identified, analyzed, and categorized to measure their usage frequency. The different algorithms and input variables extracted from each paper are graphically represented in this document highlighting the most employed ones. The findings suggest that more research needs to be conducted on the use of machine learning algorithms on this topic in Africa. In the reviewed papers Fuzzy-based algorithms are commonly used. The groundwater level prediction studies primarily focus on input variables related to hydrology/hydrogeology, while for potential mapping, geological aspects are the most investigated variables. In terms of climate, precipitation receives the most attention in the reviewed studies. The study highlights the potential of machine learning in improving water resource management and decision-making in the region.  \nKeywords Groundwater level prediction · Groundwater potential mapping · Machine learning · Africa  \n1 Introduction  \nGroundwater, which is the water occupying all the voids within a geological stratum is the main source of potable water for the majority of Africans [1]. According to the United Nations of Environment Programme (UNEP), 75% of Africans, mainly in Northern and Southern Africa, rely on groundwater as their primary drinking water supply [2] . It has been estimated that around 2 billion of the global population relies on groundwater as their primary water source [3]. This includes  \n* Cyril D.
