Abstract

Purpose

This paper aims to understand the impacts of climate changes on groundwater resources in the African continent in which groundwater components constitute one of the most indispensable resources for development.

Design/methodology/approach

Observed data are used for the first time to illustrate the manifested impacts of climate changes on the groundwater resources either directly or indirectly, this includes the comparison between isoheytal maps as well as water level data versus time.

Findings

The results of the analysis suggest that climate change is likely to impact groundwater resources, either directly, e.g. via changing precipitation patterns, or indirectly, e.g. through the interaction of changing precipitation patterns via changing land‐use practices and water demand. These changes may concern both groundwater quantity and quality. Climate change will affect groundwater recharge rates, i.e. the renewable groundwater resource, and groundwater levels. Any decrease in groundwater recharge will exacerbate the effect of sea‐level rise. In inland aquifers, a decrease in groundwater recharge can lead to saltwater intrusion of neighbouring saline aquifers, and increased evapotranspiration in semi‐arid and arid regions may lead to the salinisation of shallow aquifers.

Originality/value

In Africa, climate change and variability have the potential to impose additional pressures on water availability, water accessibility and water demands which will directly be impacted on eradicating poverty as a direct consequence of climate changes on sustainable development in Africa. A more refined understanding from specialists should be addressed to raise public and stakeholder awareness in this respect.
