What is a Nexus?

A nexus is a connection or series of connections linking two or more things. The world’s food, water and energy systems are tightly interlinked. Water is needed to extract energy and generate power; energy is needed to treat and transport water; and both water and energy are needed to grow food.

The world’s growing population will put pressure on global demand for food, water supplies and cleaner energy in the coming decades.

As a result, this relationship between energy, water and food is appearing on the agendas of governments, NGOs and businesses across the world, challenging policy makers at the highest levels to collaborate and work together across industries and sectors to develop sophisticated and innovative global solutions.

But policy shapers know they need to support the development of nexus thinking long before it reaches corporate, government and non-governmental organisations. The NXplorer programme introduces this nexus challenge and complex way of thinking to young people, equipping them with the understanding and skills that could offer solutions to these fundamental challenges.

Case Studies

Each of these case studies highlights a different challenge, or set of challenges, relating to the nexus. They present real, relevant and complex issues that require NXthinking to bring about positive change.
