For many it’s a reason to highlight the very real and critical challenges the population of the planet are facing in terms of water and how it interconnects with food, energy and global warming or in other words – the Nexus.
Nexus is a word you’re likely to hear more about over the coming years as it’s a relatively new (and strikes me as obvious) way of thinking that recognises the critical interdependence of water, energy and food. The short video clip below from the IIEA video explores the deep connections between the three essential resources and highlights the need for nexus thinking to help meet the world’s needs, as it grows from 7 to 9 billion by 2050.

To survive the impending environmental crisis and our increasing dependence on water and energy as the global population grows, decision makers are going to have to talk and agree with one another as well as engage with all communities, from industrial, business and local as well as global, and discuss integrated approaches and solutions to water-energy-food issues.
Irrigation for Agriculture accounts for 70% of global freshwater withdrawls
UN Water reports that “water for irrigation and food production constitutes one of the greatest pressures on freshwater resources. Agriculture accounts for around 70 percent of global freshwater withdrawals, even up to 90 percent in some fast-growing economies. The world population is expected to rise from 7 billion people today to 9 billion in 2050, leading to a 60% increase of the food needed globally and a 19% increase of agricultural water consumption.”
It strikes me that it’s going to take some very strong leadership qualities to pull off a combined wind-energy-food policy that’s not worried about votes and re-elections but has the interest of the planet in mind and not just those of the of rich and powerful energy and agribusiness’. It’s also going to take a shift in our own perceptions in that we’re going to have to wake up and accept that life isn’t always going to be as comfortable as we’ve known it.
“Water and energy are among the world’s most pre-eminent challenges. This year’s focus of World Water Day brings the issues to the attention of the world,” said Michel Jarraud, Secretary-General of the World Meteorological Organization and Chair of UN-Water, which coordinates World Water Day and freshwater related efforts UN system-wide. “These issues need urgent attention – both now and in the post-2015 development discussions. The situation is unacceptable. It is often the same people who lack access to water and sanitation who also lack access to energy, ” said Mr. Jarraud.
The 2014 World Water Development Report (WWDR) – a UN-Water flagship report, produced and coordinated by the World Water Assessment Programme, which is hosted and led by UNESCO – is released on World Water Day as an authoritative status report on global freshwater resources. It highlights the need for policies and regulatory frameworks that recognize and integrate approaches to water and energy priorities.
If you’d like to view the report or find out more about World Water Day and why it’s so important that we all begin to understand the Nexus way of thinking, and begin to engage in collaborative discussions about it, please take a few minutes to look at the UN Water Day website and some of the links and videos it recommends.
It’s really quite eye-opening and even if your interest is only brief, at the very least it may urge you to think twice before flushing that toilet so readily or rinsing vegetables under a running tap, and may help to give an understanding of the energy it takes to allow you to do just that.
