Blockchain Revolution: How the Hive community is bringing clean water to villages in Ghana

This week we meet McSamm who fell violently ill from contaminated water in rural Ghana. He didn’t just recover though, he revolutionized access to clean water. Partnering with Hive’s blockchain community, he raised funds to install 22 boreholes in remote villages. These often solar-powered systems (minimizing electricity costs) now deliver safe water to 300,000+ people - with villagers maintaining ownership and young people learning blockchain skills for future projects.

Jungle Guardians: Greenbug’s AI sound sensors battle illegal mining & wildfires in South America’s remote rainforests

Unusual noises and AI are stopping illegal logging and saving crops in Brazil. We met Greenbug founder Marcelo Vieira at Web Summit Rio and he revealed how Greenbug’s AI-powered acoustic sensors listen 24/7 for threats in ecosystems like the Amazon. These ‘digital guardians’ detect illegal mining equipment, smuggling boats, wildfires, and even invasive species - sending real-time alerts with geolocation to rangers and farmers before disasters escalate.

The programme is presented by Gareth Mitchell and the studio expert is Ania Lichtarowicz.

No Internet for a year: Why Equatorial Guinea has kept Annobón island offline

For 12 months, the people of Annobón, an island province of Equatorial Guinea, have lived in a digital blackout - cut off from the world with no explanation. Why would a government deliberately silence its own citizens? In this episode of Somewhere on Earth, we speak with Tutu Alicante (EG Justice) and Felicia Anthonio (Access Now) about the shocking reality of one of the world’s longest-running internet shutdowns. Digital rights groups are now demanding action - but will the world listen? 

From oil giant to climate ally? How Petrobras is unlocking emissions data for the world

What if the key to fighting climate change wasn’t just more data - but making it accessible to everyone? In a groundbreaking partnership, Brazil’s Petrobras and tech hub CESAR have transformed dense emissions reports into an interactive public dashboard tracking G20 nations’ climate progress. Could making this complex scientific data easily accessible and understandable bring real change?

The rising energy cost of AI & how tech impacts sustainability

The growing demand for AI comes with a staggering energy price tag. Research by Alex de Vries reveals that AI could consume nearly half of global data centre power by the end of 2025, surpassing even cryptocurrency mining. As models like DeepSeek AI advance, so does their electricity consumption, raising urgent questions about sustainability. How can tech companies balance innovation with environmental responsibility? And could policy changes or more efficient hardware help reduce AI’s carbon footprint? Digiconomist Alex De Vries is on the show.

Fighting food waste with tech: The app rescuing surplus meals

Startups like Food to Save are tackling another global crisis: food waste. By connecting restaurants, bakeries and takeaways with unsold meals to people who need them, the app turns nearly expired - but perfectly safe - food into affordable "Surprise Bags." Could this model work worldwide? From Kenya’s food waste challenges to AI predicting food insecurity using satellite data, innovative solutions are emerging. Hear from Food to Save’s co-founder Lucas Infante on how tech can help reduce waste—one meal at a time.

Next-Gen Black Boxes: Saving lives with Real-time Data

Traditional black boxes—Cockpit Voice Recorders (CVR) and Flight Data Recorders (FDR)—have critical flaws. CVRs often overwrite audio after just two hours, while FDRs require physical recovery, delaying crash investigations. Honeywell’s new HCR-25 solves these issues with a 25-hour CVR and live satellite data streaming, ensuring instant access to flight data even if the physical box is lost. This tech could have transformed probes like the Air India 171 or Air France 447 investigations, where recovery took years. Though retrofitting costs are high, global regulators are pushing adoption to prevent future tragedies.

Frost Away: How Chile’s Tech Shields Farmers
