The 4 Returns framework: a guide to holistic landscape restoration is a product of true team effort with many contributions from the Commonland team and partner organisations. We would like to acknowledge and thank all our landscape partners. A special thanks goes out to those who have travelled the journey with us from the beginning: Living Lands, Grounded, AlVelAl, Wij.land, and Wide Open Agriculture, for the insights and knowledge that we have built up collectively over 12 years of testing the 4 Returns framework in landscapes. These form the basis of this guidebook. 

We would also like to thank our partners Wetlands International and the Landscape Finance Lab for their vital contributions to the 4 Returns framework in the UN Decade on Ecosystem Restoration publication on the 4 Returns framework in 2021, and to the further development of tools and processes for the 4 Returns framework, which brought this guidebook to the next level. This incorporates the 5 elements from the Little Sustainable Landscape Book (2016) with refinements from the Landscape Finance Lab.
