This paper “unpacks” the nexus concept, and the authors aim to understand the differences between water, food and energy resources, especially in terms of spatial scales. To do so, they use physical indicators to show the differences in terms of absolute magnitude of production and the distance and volume of physical trade, for seven resource categories: water withdrawal, crops, animal products, bio-energy, coal, oil and natural gas.
