“…En el caso del Plan Regulador Comunal, a pesar de que es el úni-co instrumento de planifi cación territorial de carácter normativo en la comuna, que entre sus disposiciones tiene como función referirse al uso de suelo o zonifi cación, no considera el riesgo de tsunami dentro de sus criterios de zonifi cación. Andrade et al (2010) considera que los IPT frente a las nuevas dinámicas de los procesos de cambio en Corral no están lo sufi cientemente adaptados a la naturaleza y velocidad de las transformaciones que ocurren, en particular las asociadas al desarrollo inmobiliario y a la ocupación industrial, como tampoco respecto de las necesidades de protección de las zonas frágiles, a partir de criterios de mayor sensibilidad que los aplicados hasta ahora.…”

RESUMENEl análisis de la evolución del repoblamiento y uso de áreas afectadas postsunami, cobra importancia después de los últimos eventos catastrófi cos de Chile y Japón. Sin embargo, por tratarse de eventos recientes, se carece de una perspectiva de largo término. El presente estudio explora la evolución del repoblamiento y actividades productivas de un poblado ícono de la destrucción generada por una catástrofe ocurrida en Chile, hace medio siglo: el terremoto y tsunami de 1960 en Corral. El estudio se desarrolló a través de tres métodos: i) análisis de fotografías aéreas antiguas, ii) encuestas a sobrevivientes, y iii) análisis de los Instrumentos de Planifi cación Territorial (IPTs) entre 1960 y 2009. Los resultados indican que las áreas inundadas en 1960 fueron nuevamente repobladas y que la percepción actual frente al riesgo es baja. Por otro lado, se detectó la falta de carácter normativo de esta temática en los IPTs vigentes a nivel comunal.Palabras clave: Tsunami 1960, desastre, gestión del riesgo. ABSTRACTPost-tsunami analysis of the evolution of resettlement and land use changes in affected areas has become particularly important following the latest catastrophic events in Chile and Japan. Nevertheless, due to the recent nature of these events there is a lack of long-term perspectives. The present study explores the evolution of resettlement and productive activities within a town representative of the destruction generated by the catastrophe that occurred in Chile half a century ago: the earthquake and tsunami of 1960 in Corral. The study used three main methods: i) analysis of old aerial photographs, ii) interviews with survivors, and iii) analysis of Instruments of Territorial Planning (IPTs) between 1960 and 2009. The results show the 1960 inundated areas were resettled again and that the current risk awareness is low. Additionally, it was detected that there is a lack of regulation regarding this topic in the IPTs in existence at a local level.

“…[14]). These characteristics are configured by their unique climate, hydrology and geomorphology [15], especially in more natural areas, making these spaces very valuable from the ecologicalenvironmental point of view and particularly attractive for human settlement [16]. This particular set of conditions gives rise to a growing interest in the spatial planning of coastal zones, with the aim of balancing the numerous demands on the land and preventing the effects of natural hazards.…”

“…The principal instruments are the Communal [Municipal] Regulatory Plans (PRC), which act as norms and bring together the guidelines and standards of higher levels of government, such as the Intercommunal Regulatory Plan [79][80][81]. However these "instruments of a normative character (IPT) are not properly suited to the nature and speed of the transformations which are occurring in coastal zones, in particular associated with housing development and industrial occupation, nor to the need to protect fragile zones based on more sensitive criteria than have been applied to date" [16].…”

Coastal zones are very dynamic and fragile environments, constituting a landscape ever more heterogeneous, fragmented and with increasing levels of complexity due to the changing relationship between man and nature. Integrated coastal zone management therefore requires detailed knowledge of the system and its components, based-to a large extent-on technical and scientific information. However, the information generated must be in line with the political requirements necessary for decision-making and planning. Thus the use of indicators to give a simplified view of the many components of the territory, and at the same time to provide important information about patterns or trends, becomes a tool of the utmost importance. These indicators can be understood as measurable characteristics of the environment, which facilitate comprehension of the processes occurring at different scales and serve as a reference to inform the population and support decision-making. The aim of the present note is to demonstrate briefly the need to develop geographical-environmental and natural risk indicators to facilitate comprehension of the dynamic of spatial and temporal landscape patterns, particularly in coastal environments. This approach offers an historical summary of the natural, socio-economic and political processes which currently make up the territory, and which without doubt will continue to influence it in the future. At the same time, it is proposed that information should be integrated on the basis of this framework with a view to generating spatial decision support systems in a context of planning and integrated management of the coastal zones of Chile.

Identifying and analyzing the effects of anthropogenic drivers on ecosystems is a critical step in conservation planning. This chapter identifies and analyzes the evolution of direct and indirect drivers of change in the ecosystems of Chile's Patagonia region. We analyzed native forest degradation, mining expansion, tourism, energy generation, agriculture and livestock, and fisheries and aquaculture production as direct drivers. As indirect drivers we included demographic dynamics, economic growth, and institutional factors. Using a cluster analysis, we identified eight types of municipalities that reflect differentiated territorial characteristics and dynamics in terms of these drivers. These included municipalities characterized primarily by dynamics of urban growth, mining, tourism, aquaculture, forest exploitation, livestock development, and particularities in the ethnic composition of the territories, as well as municipalities where the drivers were concentrated in a non-distinguishable way. This diversity of situations suggests the need for differentiated conservation strategies that target the specific pressures on the different ecosystems and territories of South Patagonia.
