HILDA+ Global land use change

Understanding the dynamics of land use change is critical in tackling global societal challenges such as food security, climate change, and biodiversity loss. By combining multiple open data streams (remote sensing, reconstructions and statistics) we created the HIstoric Land Dynamics Assessment + (HILDA +), a global map set on annual land use/cover change in 1960-2019 at 1 km spatial resolution.

We estimate that land use change has affected almost a third (32%) of the global land area in just six decades (1960-2019) and, thus, is around four times greater in extent than previously estimated from long-term land use reconstructions.

We identify geographically diverging land use change patterns, with afforestation and cropland abandonment in the Global North and deforestation and agricultural expansion in the South (see figure).
