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.

The link between energy and water greatly impacts the food sector, the EDF says. Stakeholders are increasingly talking about the energy-water-food nexus and how to manage growing populations and the demand ...  on all three resources, the organization says. The EDF recommends creating a systematic approach to solve the interconnected issues the link energy, water, food and climate change. The EDF points to a declaration submitted to the Secretary-General of the United Nations by 300 delegates from 33 countries centers on the idea that Earth and the communities that live on it are part of a system.

Science Unstained

The event Smart Solutions for 2050: “Water, Food, Energy, Climate” was sponsored by Shell. The blogger debates the inpact of this fact on the event itself, as this is the topic of the blog: “We think the ...  public discussion of science and technology should be kept public. We appreciate that private funding is a big part of science, but it doesn’t have to frame public debate about it.”

Water-Energy Nexus

The energy-water nexus is gaining traction with diverse stakeholders around the world and it is becoming increasingly clear that we cannot plan for our planet’s future if we do not consider energy and water together. - By Kate Zerrenner.

Most recently, the United Nations celebrated World Water Day, launching a yearlong effort to highlight the global energy-water nexus, the chosen theme for 2014. In honor of World Water Day, the International Energy Agency (IEA) released its annual World Energy Outlook report, the first analysis of its kind to look at the impacts of water scarcity on the global energy sector. This signals a big step in the global understanding of the importance of the energy-water nexus, and reveals important insights on how regions, nations, and industries must cope with less water in a changing climate.

Nexus in Egypt

The study focuses on food security, energy supply and water management and how these sectoral parts can be brought to the water-food-energy nexus. State-owned German implementing agency Gesellschaft für Internationale Zusammenarbeit (GIZ) commissioned the study.

The water, energy and food security nexus means that the three sectors — water security, energy security and food security — are inextricably linked and that actions in one area more often than not have impact in one or both of the other areas. These linkages have always been present, but the world population hurdles towards 8 billion with increasing demands for basic services and growing desires for higher living standards.

Developing countries will be the most vulnerable to increased pressure on water and energy resources, and the impacts of climate change, as they often lack the regulatory framework and infrastructure to mitigate increasingly variable water supply.
