However, we find that even the richest countries are facing critical deficits in WEF. In addition, we observe that land is the base of WEF and is positively correlated with all of its elements.

To evaluate the role of money in the WEF nexus, we also convert all the elements of the nexus, in energy units. Therefore, we have used the data of gross domestic product (GDP) and the price of electricity of each country in order to convert money to stable energy units. Money controls the trading, but money is just a convention and not a stable measure. However, the elements of WEF are not equally distributed, and the dynamics of trading drives the distribution of goods. The water–energy–food (WEF) and land nexus is a basic element of prosperity.
