Particularly in the context of the EU Deforestation Regulation agroforestry land must be clearly distinguished from forest land. A first attempt to estimate the global area of agroforestry was made by Zomer et al. (2009)1who suggested that agroforestry covers about 46%(>10% tree cover) of the agricultural land globally. For Europe, they estimated an impressive 40% (91 million ha) of agricultural land covered by agroforestry. Later studies, using a pan-European database called LUCAS (Land Use and Land Cover Data)2, derived a wide range of estimates ranging from 11.4 Mha3to 15.4 Mha4to 20.3 Mha5or even 40.8 Mha6. Methods using LUCAS in Europe therefore have accuracy and methodological issues7, which can best be resolved by open access national farming statistics8. Agroforestry has significant climate change mitigation potential because it stores carbon in biomass and soil. Of all man-made systems which also contribute to food production, agroforestry stores the highest amounts of carbon9,10,11. Temperate agroforestry systems store less carbon compared to tropical systems, but as a large part of Europe is covered by agriculture (about 40%of the total land area), giving a large potential for additional carbon storage. The DigitAF project is exploring different methods to estimate the extent of agroforestry and Trees outside the Forest. This project has received funding from the European Union’s Horizon Europe research and innovation programme. Grant agreement: 101059794 References 1Zomer et al. 2009. Trees on Farms.

Currently there are 108.9 million hectares of agricultural land (59%of the agricultural area) without any trees. There is much to be done to improve this estimate at EU level, and DigitAF intends to replace the 100m Copernicus Tree Cover Density product with the 10m version and to use LPIS data rather than Corine. An "integrated rural land-parcel-registry" would greatly facilitate this move to land-diversity mapping and potential CAP "payment by results" schemes. Figure 1. Tree cover density (% tree cover in 100 m pixels) in cropland/grassland in the 39 EEA countries12. The deep red areas are priority planting areas where tree cover density is particularly low. They are usually on mineral soils where agroforestry will make the greatest contribution to carbon sequestration. Copernicus tree cover density 2018 superimposed on CORINE agricultural land 2018.

The LPIS integrator homogenizes this data and allows panEuropean query and viewing. A harmonized and better accessible LPIS registry could form the foundational basis for estimating agroforestry area and a "geospatial carbon removals registry“. www.digitaf.eu Scan to download this poster from Zenodo!
