In a quiet corner of Narok, Kenya, the dense green of the Mau Forest meets a patchwork of farmland—a boundary not just of ecology, but of human choice. This edge, like thousands of others across the globe, holds a hidden promise: that how we use land today can shape a future where nature thrives, climate goals are met, and economies grow. A groundbreaking study led by the University of Minnesota, analyzing 146 countries, reveals that smarter land use isn’t just possible—it’s already within reach. For decades, the narrative has been that protecting nature comes at the expense of economic progress. But this research flips the script, showing that the world’s lands are currently operating far below their full potential, trapped inside what scientists call a “landscape efficiency frontier”—a sweet spot where biodiversity, climate action, and economic value can rise together.
The study, published in Science, integrates biophysical and economic data to map what each country could achieve if land were managed more strategically. The results are staggering: across the 146 nations studied, better land use could unlock an additional 200 billion metric tons of CO₂ equivalent in climate mitigation—more than a 20% increase—without sacrificing biodiversity or expanding farmland. At the same time, net economic value from agriculture, forestry, and livestock could soar by over $350 billion, an 80% gain. These improvements don’t rely on futuristic tech or sweeping policy overhauls. Instead, they come from two proven strategies: restoring forests in areas where they grow best and intensifying crop production in regions with low yields, particularly in lower-income countries.
Lead author Stephen Polasky, a Regents Professor at the University of Minnesota, emphasizes that the goal isn’t to pit conservation against development, but to show that both can advance. “We know we're facing both a climate crisis and a biodiversity crisis, but usually, the pushback against doing something about either is that it's going to cost too much,” he said. “One of the main reasons for doing this study was to show, in fact, that there are ways where we can be more efficient and address climate and biodiversity without bankrupting people.” The findings are already being put to work—teams are collaborating with the World Bank to run country-specific models that can guide real-world decisions.
Becky Chaplin-Kramer, Global Biodiversity Lead Scientist at World Wildlife Fund-US, called the research a turning point: “This proves that the supposed tradeoff between protecting nature and growing economies is false.” The study doesn’t yet account for all ecosystem services—like clean water or pollination—but even in its current form, it offers a powerful tool for policymakers and investors. As nations grapple with overlapping crises, this work offers not just data, but hope: that with smarter choices, the land beneath our feet can heal the planet and sustain us all.
