The Regional Land Management Plan (PROT) is an administrative planning instrument introduced in Chile in 2018 by Law n. 19.175, constitutional organic law on regional government and administration, whose national policy has been adopted in 2021 and whose regulations are under development. In the framework of the Chilean regionalization process, the legislator sought with the PROT to decentralize to the regions key administrative planning competences for sustainable development and the climate crisis. The instrument is regulated by a regulatory framework largely composed of recently adopted norms that have not been fully implemented, in particular due to the recent introduction by the Climate Change Framework Law of 2022, of the climate variable in numerous administrative procedures. The introduction of the latter impacts the creation, adoption and implementation of the PROT creating new duties for the Administration and making procedures more complex. This study, based on a dogmatic and critical analysis of the set of norms that regulate the PROT, argues that the absence of a stable and coherent regulatory framework, as well as the increase in conflicts between public entities, represent major obstacles to the fulfillment of the objectives of the instrument in terms of prevention and mitigation of the effects of climate change.El Plan Regional de Ordenamiento Territorial (PROT) es un instrumento de planificación administrativa introducido en Chile en 2018 por la Ley n. 19.175, orgánica constitucional sobre gobierno y administración regional, cuya política nacional ha sido adoptada en 2021 y cuyo reglamento está en curso de elaboración. En el marco del proceso de regionalización chileno, el legislador buscaba con el PROT descentralizar a las regiones competencias de planificación administrativa clave para el desarrollo sustentable y la crisis climática. El instrumento está regulado por un marco normativo compuesto en gran medida por normas de reciente adopción que no han sido aplicadas plenamente, en particular debido a la reciente introducción por la Ley Marco de Cambio Climático de 2022, de la variable climática en numerosos procedimientos administrativos. La introducción de ésta impacta la creación, adopción e implementación del PROT creando nuevos deberes para la Administración y complejizando los procedimientos. Este estudio, basado en el análisis dogmático y crítico del conjunto de normas que regulan el PROT, sostiene que la ausencia de un marco normativo estable y coherente, así como el aumento de conflictos entre entes públicos, representan obstáculos mayores al cumplimiento de los objetivos del instrumento en cuanto a la prevención y mitigación de los efectos del cambio climático.The Regional Land Management Plan (PROT) is an administrative planning instrument introduced in Chile in 2018 by Law n. 19.175, constitutional organic law on regional government and administration, whose national policy has been adopted in 2021 and whose regulations are under development.
