The Global Landscapes Forum (GLF) is the world's largest science-led platform on sustainable land use. To date, we have connected 3,000 organizations and 25,000 people through our gatherings in Warsaw, Lima, London, Paris, Marrakech and Jakarta - with 32 million others online. With science and traditional knowledge at the core, GLF aims to spark dialogue and follow-through to impact in addressing some of the most complex and multi-stakeholder problems facing our communities. Recognizing the complexity of sustainable landscapes and the need for holistic approaches, the GLF is founded on four principles, aiming to engage 1 billion people: connecting, sharing, learning and acting.
