Sunday March 22 2015, was World Water Day. I woke up on that beautiful spring morning in Vienna to the rising sunshine through a slit in the curtains and the lovely humming of birds returning from their winter hideouts some thousands of kilometers away. It was clear to me: winter has ended and spring is here. But there was another thing on my mind that beautiful Sunday morning: the theme of 2014 World Water Day, the water-energy nexus. How can anyone operationalize this concept?

The nexus refers to the notion that global systems are strongly intertwined and heavily interdependent; that systems thinking and planning is required to address persistent global challenges in an integrated way. It is a beautiful concept, no doubt, but what do we do with it?

I joked in my travels and engagements on nexus issues last year that 2014 in my view was the most nexus year. Much has been achieved in 2014: raising awareness of the linkages between water and energy ; demonstrating  that integrated approaches and solutions to water-energy issues can achieve greater economic and social impacts; identifying policy formulation and capacity development issues through which the international development community, in particular the UN system can contribute; and identifying key stakeholders and actively engaging them in the discussion on the post-2015 development agenda.

But so far, much of the work on the nexus has been on advocacy, to galvanize interests and mobilize support at the global level. As a result, the concept received widespread global attention and acceptance. The real question now is: How can we transform those commitments and interests into operational frameworks for programs and initiatives? I woke up thinking of three areas:

  1. Supporting nexus assessment to understand the interactions between various nexus dimensions as countries review and roll out new policies. The objective will be to inspect the performance of current policies in terms of resource use efficiency and productivity in order to facilitate the technical interventions that will be required.
  2. Strengthening consultations and engagement among relevant sectors for various nexus dimensions. This will help decision makers anticipate, plan, and manage interventions collectively and to re-think policies and strategies to deal effectively with a range of complex interactions that are interlinked and interdependent.
  3. Reinforcing the enabling environment to facilitate the transitions that are required. This will require action to support key institutions, policy transitions and facilitating public/private funding mechanisms and investment frameworks that are required for nexus interventions.

How do we do this? First, we need to understand the interactions for a given unit of management. It could a country, a river basin, a municipality, a region or sub-region. Then we need to get various spheres of interest engaged in constructive dialogue, both in planning and in resource allocation and utilization. And probably even more importantly we need to provide the institutional, financial, and human capacity requirements to turn ideas into actions.

The challenges are huge in some regions but progress can be achieved with significant multiple gains if we get the assessments right, if we can get key sector actors to continuously talk to each other, and if are able to strengthen the enabling environment to facilitate actions. We need to act before the interest we have generated in the last couple of years diminishes.
