Caracterización del proceso histórico de balnearización del frente litoral de Puerto Madryn (Chubut) desde sus inicios hasta la actualidad
The objective of this paper was to analyze the occupation of the coastline of Puerto Madryn, province of Chubut, from its foundation to the present day. It describes the process of seaside resort development and identifies the different models of facilities built on the beach. For this purpose, a bibliographic and photographic review and a documentary search were carried out and events, actions and social processes that have modified the coastline from 1865 were recorded. The geo-historical approach complemented by Dagwood's "sandwich" methodology was applied. The compilation of facts and specific actions for the occupation of the studied waterfront allowed the identification of a continuous process of coastal transformation. Six temporal sections were distinguished; they illustrate relevant changes in the processes of anthropic intervention on this space: 1865-1914, 1915-1929; 1930-1959; 1960-1979; 1980-1999, 2000-present. It is concluded that the occupation of the coastline and the consequent territorial transformation has been taking place with greater intensity for over two decades through a sustained process of coastal seaside resort development and its associated impacts. The seaside resort models described in this study lay the foundations for the proposal of actions for the sustainable occupation of the dune-beach system in Puerto Madryn's waterfront.
