By Kate Zerrenner (EDF) and Dylan Dupre (CalCom Energy). Across the US, farmers face unrelenting pressure to conserve both water and energy. From California to Texas, recent droughts and declining groundwater levels require more pumping to provide irrigation water for crops. Pumping water takes energy, as do many other precision agriculture tasks involved in running a successful farm today. This symbiotic relationship between water and energy use – often called the energy-water nexus – is taking...// more
By Anders Jägerskog. Groundwater is fast disappearing in the Middle East and North Africa region. Under a business-as-usual approach to the use of these scarce resources, it is estimated that they will be gone in about 30 years.

"I do not think we need to abandon the Nexus concept," says Oliver Taherzadeh. "The Nexus agenda has sparked an interesting and necessary discussion around the reconciliation of environmental goals.

This growing city also has a powerful role to play in the future of Texas and the United States in terms of climate change and air quality, as evidenced by its initiatives around...// more

Yet, while this water crisis has been making headlines worldwide, nobody’s talking about the connection between water and energy. In a rapidly changing climate, we should.// more
By Kate Zerrenner. Energy Secretary Rick Perry is trying to prop up coal and nuclear companies under the guise of enhanced “resiliency.” The Department of Energy’s (DOE) proposal does not define resiliency, nor does it even make clear what resiliency means in the context of the electric grid.// more
By Raimund Bleischwitz. The major changes that have occurred across the world call for a new approach to sustainability – one that is driven from the bottom up, rather than by governments.// more

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.
