Bibliometric analysis of water–energy–food nexus: Sustainability assessment of renewable energy
2020
Sarkodie, Samuel Asumadu | Owusu, Phebe Asantewaa
Water–energy–food nexus has received global attention, as the interdependency of these resources is crucial to developing conceptual tools for environmental sustainability. Thus, water–energy–food nexus underpins economic development and improves life and well-being. We provide a critical assessment of extant literature on water–energy–food nexus using bibliometric analysis within the last 2 years. Using the keyword “Water-Energy-Food” from 2017 to 2020 in Scopus, data on 235 documents after preprocessing were used for further investigations. We found that scholarly research on water–energy–food nexus is expanding rapidly because of its policy implications. However, results and policy effects were heterogeneous because of a lack of a common conceptual framework of water–energy–food nexus—making the conceptual tool more challenging. Although renewable energy technologies have been described as the antidote for achieving environmental sustainability, however, a sustainability assessment revealed that while fossil fuel energy technologies compete with water withdrawal and consumption, some renewables compete with food for land-use—a situation that requires cost and benefits policy estimation. This article thus highlights that the effect of water–energy–food nexus on environmental sustainability depends on several socioeconomic factors that require attention.
