Description

Overview

Nexa is a funding opportunity launched by Grand Challenges Canada and the Science for Africa Foundation, in collaboration with a global consortium of partners and funders. The initiative seeks bold, innovative solutions that address climate-related health challenges in Africa, Latin America, and the Caribbean.

The programme focuses on supporting locally developed approaches that enable health actors to use climate-driven health risk information to improve timely health service delivery and reduce health impacts.

Key Details

Purpose and Strategic Focus

Nexa aims to support innovative solutions that bridge climate intelligence and health system responses. The programme addresses the growing impact of climate change on public health by enabling local health actors to identify risks earlier and implement timely interventions.

The initiative seeks to strengthen locally driven innovation ecosystems and improve resilience against climate-related health threats.

Priority Areas

The funding opportunity focuses on solutions that help translate climate-related health risk signals into actionable health service delivery responses, particularly in relation to:

• Mosquito-borne infections: Solutions that improve prediction, prevention, monitoring, or response to climate-sensitive infectious diseases.
• Extreme heat: Approaches that reduce health risks associated with rising temperatures and heat events.
• Poor air quality: Innovations addressing health impacts linked to air pollution and environmental exposure.

Eligible solutions are expected to connect climate data, health information, and practical interventions that can improve outcomes in affected communities.
