En un mundo en constantes transformaciones, donde las geografías urbanas adoptan nuevas morfologías, áreas urbanas, edificios y espacios abiertos atraviesan ciclos de alta y baja utilización durante los cuales existen momentos de transición, incertidumbre e inmovilidad. Factores como desastres naturales, cambios económicos o políticos pueden llevar al entorno construido a un estado de incerteza entre viejo y posible nuevo destino. Este fenómeno ha llevado a los diversos actores, a repensar y muchas veces reactivar este tipo de espacios a diversas escalas, dando lugar a transformaciones al interior de la ciudad ya construida a partir de procesos de reconstrucción sobre sí misma como principio genérico. Ello desde diversas prácticas compuestos por el prefijo re –que desde variados puntos de ingreso– buscan construir la ciudad desde la tabula plena, en lugar de la tabula rasa, planteando el futuro a partir de la reutilización de las huellas anteriores, reactivando e iniciando nuevos ciclos al interior del palimpsesto. En este contexto general, la tesis de doctorado La Tabula plena que cambia: Valle Central de Chile a través de Talca y sus muchos pequeños cambios significativos explora como este fenómeno –predomínate en ciudades del norte global, mayoritariamente imposibilitadas de seguir creciendo– se manifiesta en el Valle Central de Chile. Una región geográfica que debido a recurrentes terremotos, genera, acelera e impulsa las condiciones para una constante transformación de su tejido urbano consolidado, posicionándola como un área particular y fértil, a nivel mundial, para estudiar el fenómeno. Ello desde un contexto donde expansión y transformaciones en la ciudad ya construida suceden simultáneamente. La investigación parte de la hipótesis heurística de que muchos pequeños cambios significativos, ocurridos en la tabula plena, en su conjunto están radicalmente transformando las ciudades del Valle central de Chile. Para examinar esto, se analiza el caso de Talca entre 2008-2024, indagando cómo los numerosos términos urbanísticos iniciados con el prefijo re, empíricamente han modificado la ciudad. Ello a fin de indagar ¿Cómo se manifiestan las transformaciones ocurridas en la tabula plena de la ciudad en Valle Central de Chile?, ¿Qué revelan estos cambios sobre las dinámicas urbanas en la ciudad ya construida? ¿Es necesaria una comprensión integral del fenómeno? Los hallazgos se presentan en una tesis estructurada en cuatro capítulos, que, tras exponer las transformaciones, se adentra en la necesidad de generar una denominación capaz de generar un cuadro de comprensión integral del fenómeno, útil para iniciar una instrumentalización efectiva que ayude a los distintos actores a dialogar pos de construir un proyecto urbano –explicito o implícito– en resonancia con la posibilidad de concebir la ciudad, el espacio urbano y sus componentes como recursos renovables.

Abstract
In a world of constant transformations, where urban geographies adopt new morphologies, urban areas, buildings, and open spaces go through cycles of high and low utilization, within which moments of transition, uncertainty, and immobility emerge. Factors such as natural disasters, economic shifts, or political changes can bring the built environment into a state of uncertainty—caught between an old and a potential new destiny. This phenomenon has led various actors to rethink—and often reactivate—these types of spaces at multiple scales, resulting in transformations within the already-built city through processes of reconstruction upon itself as a generic principle. These processes are articulated through various practices formed around the prefix re—which, from multiple entry points—seek to build the city from the tabula plena rather than the tabula rasa, projecting the future through the reuse of previous traces, reactivating and initiating new cycles within the palimpsest. In this broader context, the doctoral research The Changing Tabula Plena: Chile’s Central Valley through Talca and Its Many Small Significant Changes explores how this phenomenon—predominant in cities of the Global North, where further expansion is often no longer possible—manifests in Chile’s Central Valley. A geographic region that, due to recurrent earthquakes, generates, accelerates, and fosters the conditions for the constant transformation of its consolidated urban fabric, positioning it as a particularly fertile ground, on a global scale, for studying this phenomenon. All of this occurs within a context where expansion and transformation of the already-built city happen simultaneously. The research is based on the heuristic hypothesis that many small significant changes, occurring within the tabula plena, are collectively and radically transforming the cities of Chile’s Central Valley. To examine this, the case of Talca between 2008 and 2024 is analyzed, investigating how numerous urban planning concepts prefixed by re- have empirically modified the city. This leads to key research questions: How are the transformations of the tabula plena manifesting in the cities of Chile’s Central Valley? What do these changes reveal about urban dynamics within the already-built city? And is a comprehensive understanding of the phenomenon necessary? The findings are presented in a thesis structured in four chapters which, after laying out the transformations, delve into the need to establish a denomination capable of offering an integrated conceptual framework of the phenomenon—one that can initiate effective tools to help various actors engage in dialogue toward building an urban project—explicit or implicit—that resonates with the possibility of conceiving the city, the urban space, and its components as renewable resources.File | Dimensione | Formato | |
