About the Nexus Blog

The Nexus Blog is a series of articles published during the Bonn2011 Nexus Conference. It aimed at creating debate and discussion around new approaches to address the critical resource challenges we face, which consider the interconnections within the water, energy and food security nexus.

In order to harness the voices of stakeholders around the nexus approach, the Stakeholder Forum for a Sustainable Future coordinated the Nexus Blog and invited a wide range of contributors with experience and expertise in at least one of the three nexus areas to submit an entry to the Nexus Blog.

The Nexus Blog is closed now.
