Comunitarius is a volunteer group of researchers, students and local leaders in Brasilia, Brazil who aim to positively transform cities and improve food security by introducing sustainable urban planting initiatives. The volunteers first identify locations where community members are affected by hunger and poverty. They then host campaigns to obtain donations of seedlings, organic manure, land and basic equipment. In the project’s final stage, volunteers mobilise community members to plant, grow and cultivate their own food. Along with this project empowering community members, it also increasing green spaces in urban areas.
