Land is a key input in economic production and production-waste sink. This links land to the causes of and responses to climate change. The dominant climate action ideas are based on the concept of 'land tenure security' which, in a global context marked by land-based inequities, means ratifying what already exists. This reinforces undemocratic social structures and institutions that themselves contribute to climate change. A restructuring of global land politics is called for, without which any analyses of and responses to climate change are at best superficial, and at worst, flawed and self-defeating. What is needed is to acknowledge the pervasive land-based social inequities in the world, and to end such inequities by pursuing a redistribution of a range of access to a range of land and resources in ways that categorically benefit the working people.
