How the Trans Africa Pipeline (TAP) Can Solve the Sahel Region's Water Crisis
with Dr. Romila Verma & Dr. Rod Tennyson

What if water infrastructure could do more than deliver clean drinking water? What if it could transform economies, support food security, reduce climate migration, and unite communities across borders? In this 3-part series, we explore the story of the TransAfrica Pipeline (TAP), a visionary project to bring clean, desalinated water across the Sahel through a 7,000-kilometre pipeline powered by renewable energy. Through conversations with co-founders Dr. Rod Tennyson and Dr. Romila Verma, we unpack how water connects to everything: agriculture, innovation, migration, environmental justice, and community resilience. TAP is more than a pipeline. It's a call to imagine water systems built with care, innovation, and the future in mind. Episode 1: The Pipeline That Could Transform a Continent How do you build a continent-sized water system? In this episode, we explore what it takes to design a 7,000-kilometre pipeline to bring clean water across one of the driest regions in the world. Co-founders Dr. Rod Tennyson and Dr. Romila Verma share the origin story of TAP, a visionary infrastructure project that combines solar-powered desalination, salt recovery, and lightweight materials to deliver sustainable water access across the Sahel. Episode 2: The Social Side of Water Water isn't just about pipes and pumps. It's about people, culture, and values. We go beyond infrastructure to explore the social, ethical, and ecological dimensions of water access. Dr. Verma introduces her Four Pillars of Water Sustainability (science, governance, economics, and cultural connection) and how these ideas can reshape how cities, towns, and regions manage water today. Episode 3: Why Solving Africa's Water Crisis Matters Everywhere From climate change to migration, the African water crisis is deeply connected to global challenges and global solutions. In the final episode of this series, we explore why water scarcity is not just a regional issue, but a global one. Through the lens of TAP, we ask: what does global responsibility look like in a time of water crisis, and what can we do to build a more secure, just, and caring future?
