The food, energy and water sectors are inextricably interlinked and face many common challenges in an era of growing natural resource scarcity, increasing environmental externalities, and lack of good governance. The importance of those linkages can be further seen through the adoption of the Sustainable Development Goals, which includes a set of goals and targets on food (SDG2), water (SDG6) and energy security (SDG7). It will be extremely challenging to achieve these goals equitably, efficiently and by 2030 due to important interlinkages and growing natural resource scarcity. This paper assesses implications for the nexus based on changes from the energy side: among the three sectors, the energy sector is most dynamic and while many linkages between the food and water sectors have been studied, energy has been neglected. This study assesses the impact of a carbon tax on fossil fuels on food and water outcomes.
