Grassland and savannah ecosystems in Argentina, Colombia and Paraguay harbour common social-cultural, economic and environmental values. They are home to unique biodiversity, ensuring water and food security, providing habitat for species, supporting livelihoods, and maintaining the cultural identity of rural and indigenous peoples. They also suffer from climate and land use change. Protected areas and low-impact cattle ranching practiced by local and indigenous communities can help safeguard these biomes. Through its 3 pillars “Protect, Manage, Restore” the project supports upscaling of existing sustainable management practices, creating resilient, connected and productive landscapes featuring sustainable food production with an aim to halt biodiversity loss and support climate change mitigation and adaptation. It will raise awareness of grasslands and savannahs on the global conservation and climate agendas, focusing on community research and south-south exchange.
