Abstract:
This article summarizes some major factors that influence the
Water–Energy–Food (W–E–F) Security Nexus and how they are
perceived in different basins. These findings are based on a
survey that was undertaken for the Global Catchment Initiative
(GCI) within the Global Water System Project (GWSP)
complemented by case studies for a transboundary basin (the
Lake Winnipeg Basin), a national basin (Yellow Basin in China),
and a number of the basins in a nation (India). The analysis also
includes ranking of river basin issues related to the WEF Nexus
based on the views of experts in nine basins. Based on this
analysis, factors that have affected the evolution of the W–E–F
Nexus, including the applications of Earth observations, are
discussed. The study concludes that the W–E–F Nexus could
be an effective vehicle for advancing water and sustainability
issues and recommends research and demonstration projects
to test the extent to which the WEF framework could be helpful
in increasing understanding and collaborative governance
approaches.
