Under SAI, global temperatures would be lower than in the SSP2-4.5 climate change scenario.
This affects malaria transmission by shifting EIR toward lower intensity valuesโmeaning fewer infectious mosquito bites.
*Cooler climate = lower EIR
5/ The length of the malaria transmission season (LTS) and overall malaria cases are also projected to decline under SAI compared to SSP2-4.5. This suggests SAI could mitigate some malaria risks associated with warming climates.
6/ Which Countries See the Biggest Changes?
The biggest reductions in EIR (๐ฆinfectivity) from 2045-2069 are projected in India & Bangladeshโthe most populous and malaria-prone nations.
Other South Asian countries (Afghanistan, Iran, Bhutan, Nepal, Pakistan) also see declines.
๐จ๐ฆCould Solar Geoengineering Reduce Malaria?๐ฆ๐จ
A new study funded by @DegreesNGO suggests Stratospheric Aerosol Injection (#SAI) could lower malaria risk in South Asia by shortening transmission seasons & lowering mosquito infectivity.

2/ Rising temps are expanding malaria-prone areas. This study examined malaria risk in 7 climate-vulnerable South Asian countriesโAfghanistan, India, Iran, Bangladesh, Bhutan, Nepal & Pakistanโunder moderate climate change (SSP2-4.5) vs. a cooler world with SAI (ARISE-SAI-1.5).
3/ Using a dynamic malaria model, researchers analyzed 3 key transmission indicators:

Brazil secured a $247M investment to restore 54,000 hectares of forests in the Amazon and Cerrado. This initiative will cut 7.75M tonnes of COโ and create 21,000 jobs.
@_Capture6, a CA-based company whose integrated system converts waste brine into both fresh water and carbon removal solutions, raised $27.5M in Series A and project funding.
A 16-year experiment in Panama shows that tree diversityโnot just tree plantingโsupercharges carbon storage. Diverse forests stored 57% more carbon than monocultures.

2/ The study, published in Global Change Biology, analyzed 16 years of data from the Sardinilla experiment in Panama.
Researchers planted forests with 1, 2, 3, or 5 tree species and tracked how carbon moved through the ecosystem.
3/ KEY FINDINGS
More species, more carbon:
โข5-species forests stored 57% more carbon in tree biomass than monocultures (35.7 vs. 22.8 Mg C/ha).
โขThese benefits strengthened over time, even under climate stress.
