The uncontrolled increase and lack of regulation of activities in the Mar Menor watershed has caused significant impacts on the lagoon. It has been necessary to update and improve the legal framework, as well as establish greater control over individuals and economic activities regarding the application of the laws to provide greater protection, reverse the pollution of the affected water bodies, and re-establish the boundaries between public and private property. Comprehensive measures have been implemented to strengthen legal oversight on various fronts and to recover natural elements belonging to the public domain through the process of demarcating the Public Water Domain (DPH) and the Maritime-Terrestrial Domain (DPMT).
The advances described in this section seek to establish greater protection against pollution with the necessary regulations to prevent activities harmful to the ecosystem of the Mar Menor and its watershed, strict compliance with existing regulations and the re-establishment of the boundaries between public and private through the process of demarcating the Public Domain.
