Agroforestry, the inclusion of woody perennials within agricultural landscape, has been both a traditional landuse approach developed by subsistence farmers and a livelihood option promoted by managers and international development efforts. Agroforestry systems range from subsistence livestock and pastoral systems to home gardens, alley intercropping and biomass plantations. These different components may account for substantial integration of green infrastructures into the agriculture sector, which may enhance a wide range of ecosystem services.
Geospatial analyses with remote sensing data show that in 2010, 43% of all agricultural land globally had at least 10% tree cover and that this has increased by 2% over the previous ten years. By combining this tree cover analysis with carbon storage estimates across different geographic and bioclimatic zones, it was estimated that agricultural land holds 45.3 PgC globally, where trees contribute for >75%. Thus, while tree cover on agricultural land is providing an important contribution for global mitigation, it is not systematically accounted for in either national or global carbon estimates for agricultural land.
The inclusion of tree cover is a significant feature of agriculture in all regions, but its extent varies significantly across different regions (e.g. more significant in Central America and less in East Asia). The average tree canopy cover in agricultural land increases strongly with increasing humidity and it is also influenced by population density with patterns varying across regions, thus depending on different regional socio-cultural contests.
