Land Use on Mars

National space agencies, including NASA, ESA, the Indian Space Agency, and the Chinese space program, all have Mars in sight. Current Mars exploration programs all have human spaceflight in mind for the near future, and eventual plans for exploration often turn to thoughts of permanent settlement or colonization. Several private corporations have also declared their intent to visit, or even colonize, Mars within the next several decades. Whether or not they succeed in their planned time frame, it seems evident that humans have their eyes on Mars.

The patterns of history show us plenty of examples of how land resources have benefited the few over the many, or how conflict over scarce land resources have led to violence and war in extreme cases. Even more fundamentally, the amount of land on a planet is finite, but it is only recently that the practice of homesteading became impossible on Earth. Mars holds the potential for settlers to once again lay claim to open areas of unclaimed land, but is this the best policy for using the resources of space?

In a book chapter published in the Springer edited volume Human Governance Beyond Earth: Implications for Freedom, I discuss my research and thoughts in an effort that will lead “Toward a Sustainable Land Use Policy for Mars.” I discuss the constrains of existing treaties governing the use of space resources, and I present a few possible alternatives for what a land use policy on Mars might look like.
