Volcanic Ash: A Unique Carbon Capture and Land Degradation Solution
While atmospheric carbon rightfully holds much of the spotlight in climate change discussions, climate change also exacerbates the often overlooked issue of land degradation, which the UN Food and Agriculture Organization describes as a “silent crisis” threatening food stability and agriculture across the globe.

Alt Carbon in Darjeeling: Brewing better soil from India’s tea country
Enhanced rock weathering capitalizes on Darjeeling’s proximity to the Himalayas and a region of high temperatures, heavy rainfall, humidity, acidic soils, and large basaltic rock deposits.
Enhanced Weathering for Corn: Promise, Limits, Direction
Two recent field studies offer the clearest evidence yet of how enhanced rock weathering behaves in the U.S. Corn Belt.
COP30 InPlanet Discussion: Gigaton-Scale Carbon Removal in Brazil
To align with guidelines of the IPCC, carbon dioxide removal (CDR) must scale rapidly to gigatonne levels over the coming decades. This was the theme of a panel discussion at the COP30 Blue Zone, where Dr. Christina Larkin, vice president of science and research at InPlanet, Dr. David Manning, professor of soil science at Newcastle University, and Dr. Injy Johnstone, an environmental lawyer and NetZero expert, further explored issues raised by the InPlanet paper Unlocking Gigatonne-Scale Carbon Removal with Strategic Tipping Point Frameworks. Together, they explored the ...
Resilient Cacao Emerges Through Enhanced Weathering Strategies
Cover of Plants, People, Planet (Vol. 7, November 2025).
Cacao’s climate footprint is far larger than most consumers imagine, and incremental efficiency gains will not be enough to secure the crop’s future. A new paper in the journal Plants, People, Planet proposes a dual strategy: agroforestry for resilience and enhanced rock weathering (ERW) for carbon removal. However, it remains to be seen how scientific promise intersects with institutional constraints.
The paper begins with an overlooked but fundamental point: chocolate is a high-emissions commodity. ...
Tera: Upcycling Sugar Cane Bagasse into Biochar
The production of biochar in Africa could reduce carbon in the atmosphere and provide farmers with a solution to soil degradation in the region.
From Mine to Field: A Circular Economy Approach
A new study places soil remineralization within the wider idea of a circular economy: rock dust should not be treated as waste but as potential inputs for farming systems.
Permaculture in Practice: Michael Pilarski and the Movement to Re-Green the Planet
Michael Pilarski is a celebrated permaculture and agroforestry instructor who has taught courses on the subject in the United States and abroad since 1988.

CDR in the Tropics: Building Trust, Markets, and Climate Solutions
When Jill Raval steps onto a stage, whether under the lights of a classical Indian dance performance or in front of a global audience of climate entrepreneurs, she carries the same sense of rhythm and intent. “I wasn’t a good student,” she admitted with a laugh during the Pioneering CDR in the Tropics webinar hosted by Milkywire on October 8, 2025. “I was much more into dancing.”
