Advances and Challenges in the Water Footprint Assessment Research Field: Towards a More Integrated Understanding of the Water–Energy–Food–Land Nexus in a Changing Climate

[...]Section 5 includes a call for action to develop papers that advance the research on WF assessment in the water–energy–food–land nexus in the context of climate change, trying to overcome the silos that prevent a more integrated management of water resources. 2. [...]most efforts have focused on reducing greenhouse gas emissions to achieve the climate targets of the Paris Agreement. Hydropower represents another example of a technology with low emission generation, but with a substantial WF [23,34]. [...]considering all footprints is necessary to better understand the impacts of the energy sector and improve decision-making regarding the energy transition [29]. [...]in the context of climate change, a greater understanding of different countries’ dependencies on the availability of water in other parts of the world for producing the different consumer products is key.
