Abstract
Ecosystem services are the benefits people obtain from ecosystems. Many of these services are provided outside the borders of the land where they are produced. This article investigates who is entitled to these non-excludable ecosystem services from a libertarian perspective. Taking a right-libertarian perspective, it is concluded that the beneficiaries generally hold the right to use non-excludable ecosystem services and the right to landowners not converting ecosystems. Landowners are only at liberty to convert ecosystems if they appropriated their land before any beneficiary used the services and converted the ecosystems before or shortly after the beneficiaries started using the services. This means that the beneficiaries generally hold the right to compensation payments by the landowners in the event of service losses, instead of the landowners holding the right to payments for ecosystem services by the beneficiaries. Taking a left-libertarian perspective, it is concluded that landowners ought to pay for the non-excludable ecosystem services lost as a result of their activities as well as beneficiaries paying for the non-excludable ecosystem services they use. These payments are not made mutually, however, but to a central authority that distributes the returns to the community on an equal per capita basis.
