The Land Matrix is an independent land monitoring initiative that promotes transparency and accountability around large-scale land acquisitions (LSLAs) in low- and middle-income countries across the world. By capturing data on its website, the initiative aims to stimulate debate on the trends and impacts of LSLAs, facilitate wide participation in collecting and sharing data about these deals, and contribute to the growing movement towards open data. In this way, it seeks to support greater public involvement in critical decisions that affect the lives of land-users and strengthen their positions in the processes that govern access to land.
