This is a commemorative publication to celebrate the GEF Small Grants Programme's (GEF SGP) 30 years of local action, global impact. The publication highlights the important role of local communities, civil society and Indigenous Peoples, youth, women, and persons with disabilities in addressing global environmental issues – such as biodiversity loss, climate change mitigation and adaptation, land degradation, international waters, and chemicals and waste management – while improving well-being and livelihoods. Throughout its journey, SGP has continuously evolved and has now grown into a unique global delivery mechanism to scale up local actions that can develop and deliver solutions to these multiple challenges.
