The Water-Energy-Food Security Nexus in Practice. Make it happen!

A central aspect of the Green Economy is water, energy and food security in particular for the bottom billion. In order to achieve this, it is of vital importance to consider the interlinkages and the interactions between the sectors. Incoherent approaches and “silo-thinking” will most likely worsen the situation further.

The Bonn2011 Nexus conference was dedicated to these questions. It triggered an international process based on initiatives from different actors. The objective of the event is primarily to inform of the conference results and to demonstrate, by means of practical experiences, what has already happened and what is planned to happen.

It should be illustrated therewith that the sustainable development objectives can only be achieved with cross-sectoral solutions. The Nexus approach will not create more complexity, but consider the impacts in other sectors and identify common solutions. The relevance of such an approach for elaborating sustainable development goals will be discussed.

The Water, Energy and Food Security Nexus Solutions for the Green Economy – Messages from the Bonn2011 Conference

There are numerous ways in which the water, energy, and food sectors are interconnected. Thus “actions in one sector” may either help or harm the other two. Disconnected approaches and silo thinking are more likely to make matters worse. The Nexus perspective helps to increase the understanding of the interdependencies across the water, energy, food and other sectors and policies such as climate and biodiversity. It opens the eyes for mutually beneficial responses and the potential of cooperation.
