Transparency and Informed Decision-Making are Crucial
As climate disasters proliferate and intensify, the need to explore unconventional tools to mitigate the effects of global warming has become increasingly pressing. One such tool is solar radiation modification (SRM), a group of large-scale interventions that aim to reduce global temperatures by increasing the amount of sunlight reflected away from Earth. However, the risks and benefits of SRM remain uncertain, highlighting the need for a thoughtful policy approach. In Africa, SRM efforts could have significant economic and social implications, diverting attention and funding away from other pressing priorities such as expanding energy access and supporting a just transition. It is essential that African policymakers and academics engage in informed discussions about SRM, guided by principles of transparency and accountability.
SRM Research is Still in its Infancy
The current state of SRM research is characterized by a focus on modeling and small-scale experiments. The most studied option, stratospheric aerosol injection (SAI), involves releasing large amounts of sulfur particles into the upper layer of the atmosphere. This process has natural analogues, such as volcanic eruptions, which can decrease temperatures. However, the potential environmental and socioeconomic risks associated with SAI, including its effects on precipitation and human health, are not well understood.
- The asymmetrical power dynamic between those funding research and those working to increase oversight of SRM must be acknowledged and addressed.
- Private-sector entities are already developing SRM technologies, which will require public authorities to establish clear rules for testing and deployment.
Facilitating Knowledge-Sharing and Inclusive Governance
To move beyond colonial forms of engagement, it is essential to facilitate knowledge-sharing between Africa and the Global North. This can involve increasing transparency, debating potential risks, and emphasizing that no single technology is a panacea. African governments, NGOs, and philanthropic organizations must engage with the fact that private-sector entities are developing SRM technologies.
| Benefits of Knowledge-Sharing | Challenges to Knowledge-Sharing |
|---|---|
| Increased understanding of SRM technologies and their implications | Power imbalance and potential for unequal distribution of resources |
| Improved governance and oversight of SRM | Resistance to change and lack of capacity-building in some African countries |
African Governments Must Prepare for the Future
African governments are grappling with the challenge of balancing climate-related investment and economic development. Trapped in a cycle of debt distress, many are struggling to restore fiscal stability, finance counter-cyclical measures to put their economies on a more sustainable trajectory, and adapt to the growing climate threat. A series of dialogues organized by the African Climate Foundation and the Alliance for Just Deliberation on Solar Geoengineering highlighted the need for better information-sharing and capacity-building in African governments, civil society, and academia when it comes to SRM. These meetings emphasized that SRM must not exacerbate inequalities and undermine climate action.
Conclusion
In conclusion, the design and governance of SRM will play an important part in determining its impact. Developing a nuanced understanding of these early-stage technologies across Africa can help guide long-term decision-making. As global warming accelerates, engaging with SRM at the regional, national, and local levels will be crucial to creating an inclusive, transparent, and accountable solar-geoengineering ecosystem on the continent. Saliem Fakir and Shuchi Talati, co-founders of the African Climate Foundation and the Alliance for Just Deliberation on Solar Geoengineering, respectively, are calling for a thoughtful policy approach to SRM in Africa. Their efforts highlight the need for transparency, informed decision-making, and inclusive governance in this rapidly evolving field.
