Territorial user rights fisheries (TURFs) are an alternative marine management strategy that gives marine users property rights over defined marine areas. However, this marine management strategy is only effective if it is enforced, i.e., there are effective mechanisms in place to (1) monitor marine areas to detect poachers; (2) institutional or local capacity to apprehend poachers or non-compliers; and (3) political will to punish non-compliance. In these articles, we discuss our work assessing the drivers of enforcement on the central coast of Chile in South America.
