Free Online edX Course // Sustainable Development: The Water-Energy-Food Nexus

Securing the supply of water, energy, and food is one of the greatest global challenges of our time. Learn all about sustainable development and global changes in this free online course.

About this course

This course focuses on sustainable development and global changes - vital issues for humanity. There is specific attention paid to the challenges in developed and developing countries and their transition from unsustainable to sustainable practices.

The course is an introduction to sustainable development and its relation to the Water-Energy-Food Nexus. This connection between three critical resources offers a conceptual tool for achieving sustainable development. It has become increasingly important to understand the interdependencies and interrelationships between the three resources. Finding new approaches to manage the nexus could contribute significantly to achieving the Global Sustainable Development Goals (SDGs).  

Topics of this course include

  • Finding new ways to face water challenges and opportunities
  • Renewable energies
  • Energy efficiency
  • Sustainable agriculture
  • Climate change
  • Rethinking established ways of resources management
  • Types of virtual water
  • The interrelationship between local and global challenges and economic as well as population growth
  • The role of technology in the WEF nexus as well as managing the nexus at local, regional, and global levels.

This course gives you a solid understanding of the connection between water, energy, and food, and enables you to manage resources in a sustainable and effective way. You’ll build skills and knowledge that are key for sustainable development into the future.

What you'll learn

  • Global challenges and their limited resources
  • How human activities can affect the climate change
  • The concept of sustainable development and global Sustainable Development Goals (SDGs)
  • Water scarcity, virtual water, and water footprint
  • How to deal with energy challenges and opportunities
  • The 'nexus' between water, energy, and food (WEF) and their security
  • Desalination in the framework of the WEF nexus
  • Dealing with the WEF nexus at local and regional levels

Nexus Modelling // Involving the Water–Energy–Food Nexus in Integrating Low-Income and Isolated Communities

By Brenda Cansino-Loeza and José María Ponce-Ortega. This work presents a general mathematical programming model for satisfying water, energy, and food needs in isolated and low-income communities involving different process integration approaches. As a case study, the community with the lowest index of poverty and marginalization from the State of Guerrero in Mexico is presented. The problem consists in determining the optimal and sustainable configuration to satisfy the energy, water, and...

Video // Green Pumps for Jordan’s Water to combat Climate Change

This video explains how highly energy efficient water pumps can contribute to improve water, energy, and food security in the water scarce country Jordan. At the same time, CO2-emmissions are lowered, which marks a significant contribution in meeting Jordan´s Nationally Determined Contributions (NDCs) to the Paris Agreement.
