We drink it, swim in it and depend on it, yet we rarely think about it until something goes wrong.

In this episode of Nature Unheard, we’re joined by Katrina Charles, Professor of Environmental Health Risks at Oxford University, and Dr Saskia Nowicki, Senior Research Associate, to explore why clean freshwater is so easy to take for granted, and what it will take to protect it in a changing climate.

As the year draws to a close, Nature Unheard unwraps a special end-of-year episode looking back at the conversations that shaped 2025, and ahead to what they could mean for 2026.

From breakthroughs in AI for climate action to major biodiversity milestones, advances in coral reef science and the rise of nature-tech start-ups, our hosts revisit the ideas, insights and moments that defined the year.

And because it’s the festive season, there’s a twist. After a year of extraordinary guests and unforgettable “nature unheard” moments, Rachael and Adonai are put to the test by Emma. Were they really paying attention, or did some wisdom remain, well… unheard?

Next episode is coming up on 08 January 2026!

In a world racing to monitor forests, wildlife and climate impacts with cutting-edge technology, millions of people still lack the basic digital tools and connectivity needed to benefit from or contribute to these efforts.

This episode explores how digital exclusion affects communities, environmental data and the ability of countries to respond to climate change. Host Rachael Barza speaks to Reina Otsuka, Global Lead, Digital for Nature and Climate for the United Nations Development Programme (UNDP) about the “digital fault lines” shaping today’s climate and nature agenda, and what it will take to close them.

The episode also examines the new and creative tools emerging across the EBRD regions, including Palmear, a startup using acoustic technology to monitor tree health. While such tools offer powerful new ways to “listen” to nature, the episode explains how they can only create impact if digital infrastructure and inclusion keep pace.
