Water is an essential resource for the realization of the United Nations’ 2030 Sustainable Development Goals. The increasing global food insecurity, hunger, human population, and uneconomical extraction and use of non-renewable resources require, among other things, a substantial intensification of agricultural production. In this context, there has been a need to adopt irrigation technologies, especially in developing countries where agriculture and its allied sectors employ more than 50% of the total population but account for up to 90% of the total freshwater consumptive use. India and Africa are at the crux of this conundrum, where there is an urgent need to build resilience with the already excessively allotted water resources. Innovative and water-efficient irrigation technologies could be one of the windows of opportunity to overcome water scarcity and enhance food security in these regions. This review sought to comparatively explore how irrigation technological interventions could help overcome water security challenges in India and Africa. Literature retrieved from multidisciplinary electronic databases indicated that, as part of the global south, both India and Africa have untapped irrigation potential due to the adoption of individual-centric irrigation. The irrigation approaches that possess the capacity to increase water and food security as well as reduce poverty levels in India and Africa are broadly grouped into micro-irrigation technologies, renewable energy-powered irrigation technologies, flood recession agriculture, and underground transfer of surface flood water for irrigation. Unlike in India, where overexploitation or extraction is the primary driver of water scarcity (physical scarcity), water insecurity in Africa results from poor management (economic scarcity). The adoption of the foregoing interventions is challenged by existing cultural and land tenure issues, limited access to efficient irrigation technologies and credit services, as well as an overreliance on national governments for support. Despite these challenges, opportunities exist for smallholder irrigation expansion. This study indicates that both Indian and African governments ought to offer stimulus packages that encourage holistic farmer-centric irrigation technologies to improve food and water security.
