As we collectively address the global climate and nature crises, it is absolutely critical to engage youth as agents of change, creative entrepreneurs and innovators. Through education, science and technology, young people are scaling up their efforts and skills to accelerate concrete actions. Through the support and partnership provided by the GEF Small Grants Programme (SGP), youth are acquiring knowledge and skills to build a more sustainable future, while actively engaging in developing a green and blue economy. This publication brings together great examples of youth innovations and intergenerational efforts on inclusive nature-based solutions to demonstrate SGP's approach to empowering young people through its grant-making process and encouraging their engagement in global issues such as climate change, biodiversity loss, and pollution.
