About the NEXUS

The challenge of thinking in a Water, Energy and Food Security Nexus perspective is central to the Green Economy and the consideration of sustainability development goals.

The Bonn2011 Nexus Conference from 16-18 November 2011 resulted, among others, in this online resource platform, which presents a large variety of documents, presentations, news, messages and other Information from various sources on the Nexus. It aims to demonstrate the relevance of a Nexus approach for sustainable development and raises awareness that more systemic thinking is needed.

If rivers run dry or we pollute them, it’s not just wildlife that suffers; water companies, farmers and power utilities are affected too. This is why governments from South Africa to Sweden have prioritised ...  the maintenance of river flows in laws, policy or guidelines. The maintenance of river flows is critical to determining the future success or failure of meeting the water security challenge. The trade-offs referred to in abstract food-water-energy nexus debates often take tangible form when decisions are made about how to use rivers like the Itchen, Godavari, Great Ruaha or Yangtze. Yet we hear little in nexus debates about these vital freshwater ecosystems. By Dave Tickner

Water-Food Nexus

Every food item we eat needs water for its production, but different foods require different amount of water. What do you think consumes more water: a steak, a glass of milk, a piece of bread or a cucumber? The short answer to this question is that the steak is the biggest water consumer. - by Ylva Ran

However, this answer is not enough, it is much more complex than it seems and requires that we understand more of the complexity behind water use in agricultural production. Regardless of whether you think livestock products is a key ingredient of your every meal or not, it is an important part of human diets globally, especially in low-income countries. 1 billion people in these countries depend on livestock, and it has a significant value for battling malnutrition in many places around the world.

In response to nexus challenges EPSRC, with input from other research councils, is running a sandpit in the water energy food nexus in order to try to engender a radical change in the research undertaken in this field in the UK. This complex area presents multi-dimensional research challenges that require a multidisciplinary and interdisciplinary approach to addressing them. It is expected that £4-5 million of Research Council funding will be made available to fund research projects arising from this sandpit with additional computational modelling support from STFC.

The Water Risk Filter

The “Water Risk Filter” is the first tool to quantify water-related risks for all industries in all countries. This tool helps companies and investors ask the right questions about water. It allows you ...  to assess risks and offers guidance on what to do in response. It’s too easy not to use. More than 1,500 organizations from 32 industry sectors have assessed facilities located in almost all of the 405 largest river basins, as well as in hundreds of smaller basins all over the world. You can look at specific facilities or agricultural commodities, each with an automated basin assessment and questionnaire to evaluate direct operations.

Interview: IUCN Director-General Julia Marton-Lefèvre answers key questions on the Water-Energy-Food Security Nexus

Many industries use water, need water, rely on water for their production. Whether this is food production, energy generation, water supply services, their business cannot work without water. Yet, with ...  so much demand, how do we ensure the sustainability of this resource? Considering the inter-dependencies, how can these sectors work more effectively together? And how can we learn from what works and benefit from Nexus solutions that already exist? In this interview, Julia Marton-Lefèvre, IUCN Director-General addresses key issues concerning the interlinkages between the water, energy, food security nexus and proposes solutions for a more sutainable future.
