About GreFA

Green Foster Action believes in action result-based approaches for climate action and environment conservation.

Green Foster Action Uganda (GreFA) is a youth-led non-profit organization legally registered in Uganda. Founded in 2022, GreFA is inspired by young people and grass root communities that stand up collectively to protect the environment and their rights. GreFA works with social movements and grass-root organizations in exposing authorities that hold power and corporations that oppress communities that face climate change impacts, water scarcity, energy deficiency, poverty, and insufficient food production, leaving people vulnerable and unable to meet their basic needs. GreFA advocates for accountability, equity, and justice.

Why now?

The political and environmental contexts that have changed in the past years have been the foundation upon which the design of our Strategic Plan was developed. GreFA has built a presence at country and regional levels ever since it was founded in 2022. We strongly believe that the voice of Civil Society Organisations(CSOs) now has a far broader reach than in the past years.

Civil Society Organisations are facing constraints to action due to regressive forces from climate change-denying regimes. They face threats, violence, unlawful arrests, or even death. A further challenge is declining donor support for advocacy work as development aid shifts ever more toward Humanitarian Assistance and Trade-Focused Economic Growth Media use of the descriptions ‘emergency’ or ‘crisis’ when referring to climate change or biodiversity loss is a strong indicator of changing attitudes and narratives which need to be addressed.
