Fig Trees Could Hold the Key to Turning CO2 into Stone, Offering Climate Change Solutions

Speedy summary

• Recent research highlighted that certain fig tree species in Kenya can sequester carbon dioxide (CO2) as calcium carbonate, effectively turning CO2 into “stone.”
• This process, called the oxalate carbonate pathway, is achieved through calcium oxalate crystals formed by thes trees which gradually convert to calcium carbonate with the help of microbial communities.
• calcium carbonate storage in soil offers advantages like increased pH and longer-lasting carbon sequestration compared to organic methods.
• notable species include Ficus wakefieldii, identified as particularly effective at storing CO2.
• Further studies are planned to examine the efficiency of this method across varied environments and explore its broader applications in combating climate change.

Indian Opinion Analysis

This research underscores a novel dimension in climate change mitigation strategies-utilizing specific trees for inorganic carbon sequestration. India could find valuable insights here given its longstanding afforestation programs and diversity of flora. Emphasis on planting species capable of similar CO2 conversion processes might bolster ecological restoration efforts while contributing to global carbon reduction targets. Scaling such initiatives would require rigorous scientific input to ensure compatibility with local ecosystems and balance between food production needs and conservation aims. Enhanced focus on tree-based solutions aligns seamlessly with India’s commitment under international frameworks like the Paris Agreement, complementing broader renewable energy developments.
