Nexa
Nexa is a climate and health initiative co-led by Grand Challenges Canada and the Science for Africa Foundation, in collaboration with a global consortium of partners and funders.
We are investing in bold, innovative solutions across Africa, Latin America, and the Caribbean that enable local health actors to turn climate-driven health risk signals into timely health service delivery action, reducing health harms from mosquito-borne infections, extreme heat, and poor air quality.
All proposals must be submitted via the Fluxx portal by July 22, 2026, at 2:00 p.m. ET (6:00 p.m. UTC).
Funding opportunity
Funding focus
Applications must directly address at least one of the following areas of focus:
- Climate-informed early warning and monitoring systems: Innovations that allow health actors to anticipate and respond to the impacts of heat, poor air quality, and/or changing mosquito ecology (resulting in the accelerated spread of malaria and dengue infections).
- Climate-responsive patient care delivery: Innovations that strengthen local response to mosquito-borne infection harms, and/or the health impacts of heat and poor air quality.
What are we investing in?
- Proof of Concept innovations: meaning the testing of early-stage ideas, methods, or products. For more detail on how Nexa defines Proof of Concept, please refer to this helpful guide: Our Investment Approach.
- Transition to Scale innovations: meaning approaches that have already been tested, proven to be effective, and are now ready to be implemented more widely. For more detail on how Nexa defines Transition to Scale, please refer to this helpful guide: Our Investment Approach.
What is the funding amount?
- Proof of Concept funding amounts are up to $200,000 USD per innovation.
- Transition to Scale funding amounts will range between approximately $250,000 – $2,000,000 USD per innovation at the Nexa partners’ discretion, depending on the maturity of the innovation.
Who can apply?
