Using causal maps to support ex-post assessment of social impacts of dams

This paper presents the results of an ex-post assessment of two important dams in Brazil. The study follows the principles of Social Impact Management, which offer a suitable framework for analyzing the complex social transformations triggered by hydroelectric dams. In the implementation of this approach, participative causal maps were used to identify the ex-post social impacts of the Porto Primavera and Rosana dams on the community of Porto Rico, located along the High Paraná River. We found that in the operation of dams there are intermediate causes of a political nature, stemming from decisions based on values and interests not determined by neutral, exclusively technical reasons; and this insight opens up an area of action for managing the negative impacts of dams.

Causal Maps and Indirect Influences Analysis in the Diagnosis of Second-Home Tourism Impacts

This paper proposes a method for diagnosing the impacts of second-home tourism and illustrates it for a Mediterranean Spanish destination. This method proposes the application of network analysis software to the analysis of causal maps in order to create a causal network model based on stakeholder-identified impacts. The main innovation is the analysis of indirect relations in causal maps for the identification of the most influential nodes in the model. The results show that the most influential nodes are of a political nature, which contradicts previous diagnoses identifying technical planning as the ultimate cause of problems.

Estructura y forma de la ciudad a través de la cartografía histórica: Castro Urdiales, Cantabria (1800-1960)

El presente artículo se plantea como objetivo el análisis de la evolución estructural y morfológica de un espacio urbano de rango y tamaño modestos, Castro Urdiales (Cantabria), desde su condición histórica de villa marinera hasta su consolidación como ciudad industrial moderna. Desde una perspectiva metodológica, la parte más substancial del análisis de la dinámica urbanística se apoya esencialmente en el uso de las imágenes cartográficas, como referencias documentales que proporcionan datos y testimonios que no se encuentran en otras fuentes. No obstante, como sucede con otras fuentes documentales, la información obtenida de mapas y planos ha sido combinada y complementada con otro tipo de fuentes coetáneas a las cartográficas. Y, por descontado, se han adoptado las oportunas precauciones, similares a las tomadas con las fuentes escritas, sobre posibles errores de información mediante el contraste y la comparación de unas y otras fuentes, cartográficas y literarias.
