A new modelling study published in Environmental Research: Climate indicates that India's forests could nearly double their carbon storage by 2100 under current greenhouse gas emission trends. The study projects vegetation carbon biomass to rise by 35% under low-emissions, 62% under medium, and 97% under high-emissions scenarios. This increase is primarily driven by rising precipitation and elevated atmospheric CO2, enhancing photosynthesis and water-use efficiency. The largest relative increases are projected in desert and semi-arid zones (Rajasthan, Gujarat, Madhya Pradesh), rather than established forest heartlands. Researchers caution that these gains may mask deeper stresses and disruptive forces like deforestation, fires, and pest outbreaks.
- India's forests have the potential to significantly increase carbon storage by 2100, possibly nearly doubling current levels.
- Projected increases in vegetation carbon biomass vary significantly across emission scenarios, with the highest under a high-emissions pathway.

New research confirms that genetically modified mosquitoes can suppress malaria parasites from real-world infections, moving closer to 'Transmission Zero.' Using the CRISPR-Cas9 gene-editing tool, scientists have developed gene drives that either suppress mosquito populations by causing sterility or modify mosquitoes to prevent malaria parasite development without killing the mosquito. A recent Nature study, led by Tibebu Habtewold and Dickson Lwetoijera in Tanzania, demonstrated the effectiveness of modified Anopheles gambiae mosquitoes in blocking malaria parasites from infected children's blood. The research emphasizes the need for extensive ecological risk assessment, regulatory review, and community engagement before wild release, acknowledging that gene drives are an additional tool, not a standalone solution.
- Genetically modified mosquitoes using gene drive technology show potential for malaria control by suppressing parasite transmission.
- Two main types of gene drives are being developed: population suppression (causing sterility) and population modification (preventing parasite development).
- A recent study in Nature demonstrated that modified Anopheles gambiae mosquitoes could block malaria parasites from real-world infections in endemic African settings.
