    Can we really put a price on nature? This nature‑finance expert says we must.

    When you clear a forest to plant maize and make charcoal, you’ve already put a price on nature—the future cash flows from the maize and the wood. The problem is that price is far too low. In this episode of The Samuele Tini Show, I speak with Josep Oriol, Managing Partner at Okavango Capital Partners and a leading nature‑finance expert working across Sub‑Saharan Africa. A Catalan who fell in love with African wildlife as a child, Josep trained as a lawyer, moved into venture capital and banking, then finally to Southern Africa to build a different kind of private equity firm—one that backs nature‑positive businesses whose performance depends on how they treat forests, soil and water. Today, Okavango‑backed companies help protect around 8–9 million hectares of land (about twice the size of Switzerland) and create income streams for hundreds of thousands of rural people. We dive into: The mispricing of nature: every land‑use decision—from forest to maize field—is already a price signal, and why that’s dangerous if we ignore the true value of ecosystems. Forest carbon in practice: the story of BioCarbon Partners, REDD+ projects, and rural families living on ~$20/month in cash who now earn income by keeping forests standing. Carbon market backlash: Josep’s response to critics of carbon credits, and why, compared to agriculture, mining or logging, high‑integrity projects are often far more transparent and generous to local communities. Three big opportunity themes: smarter agriculture and agroforestry to boost yields and cut waste, tech for soil, post‑harvest, insurance and finance, monetising ecosystem services via tourism, carbon, biodiversity and water credits—and why fuelwood is still the elephant in the room. Why classic 5‑year 10x PE funds don’t fit Africa: and how Okavango uses longer horizons and flexible instruments (loans with equity options, convertibles, prefs) instead of only straight equity. We close with Josep’s advice for entrepreneurs in nature‑based sectors—live with existential threat, love cash flow and margins, and assume everything will take twice the time and three times the money—and his vision of Africa’s future looking more like South Korea or Malaysia than Europe, if we get the nature piece right. If you care about where climate capital should actually go, this is a sharp, grounded conversation from inside the deal flow.

  2. The Most Underrated Climate Tool You’ve Never Heard Of: Biochar Explained

    The Most Underrated Climate Tool You’ve Never Heard Of: Biochar Explained

    We talk a lot about tree planting, but far less about what happens to all the agricultural and organic waste we burn or dump. That’s where biochar comes in. In this episode of The Samuele Tini Show, I’m joined by Luisa Marin, Executive Director of the International Biochar Initiative (IBI). After 25+ years in conservation with organisations like Conservation International and The Nature Conservancy, Luisa moved into carbon project development—and discovered biochar: a carbon‑rich “black sponge” made by pyrolysing crop residues, prunings, manure and other organic waste instead of letting them rot or burn. 9th December Luisa Marin (1)_ot… Done well, biochar can: Lock away carbon in soils and materials for hundreds to thousands of years Regenerate soils, boosting water retention, porosity and microbial life Cut fertiliser and irrigation needs for farmers Create new revenue streams through products and carbon credits—especially in the Global South Luisa explains how research suggests biochar could remove up to 6% of global annual emissions—roughly like switching off 800 coal plants for a year—and why just 1 gram of biochar can have the surface area of two tennis courts. She also talks frankly about “good biochar” vs “bad biochar”, the importance of standards and lab tests, and the most common mistake she sees: projects chasing carbon money without proper technical and financial feasibility or patient capital. 9th December Luisa Marin (1)_ot… We also hear real examples from Kenya, Zimbabwe, Ghana and Latin America, where farmers and communities are already turning waste into value using both industrial and artisanal kilns—with support from NGOs, digital MRV tools and local governments. 9th December Luisa Marin (1)_ot… If you care about climate action, soil health and future markets in the Global South, this episode is a clear, grounded introduction to one of the most powerful—and underrated—tools on the table.
