Catalan irrigation management: between efficiency, compatibility of uses and social legitimacy

En los años precedentes, el regadío y su gestión han devenido protagonistas de un debate social que cuestiona los límites económicos, ambientales y territoriales de su práctica en espacio y tiempo. Las construcciones hidráulicas como los canales de regadío han ocupado un papel central en el intento de “dominar” el recurso agua y controlar así el territorio. Sin embargo y, con el paso del tiempo, tanto la modernización de regadíos tradicionales como la promoción de nuevos regadíos han sido progresivamente cuestionadas ante el auge de las demandas ambientales y la promoción de la gobernanza como mecanismo favorecedor de acuerdos entre partes interesadas. En Cataluña, la gestión del regadío debe hacer frente tanto a los requisitos de eficiencia como a la compatibilidad entre usos consuntivos y no consuntivos así como a la legitimación social de proyectos que sobrepasan el interés sectorial. El análisis de la realidad asociada a los regadíos históricos del Bajo Ter y de la Muga así como del proyecto en ejecución del canal Segarra-Garrigues enfatiza en la necesidad de promover un modelo de gestión territorial del regadío capaz de integrar y legitimar distintos puntos de vista en competencia.In previous years, irrigation and its management have become protagonists of a social debate that questions their economic, environmental and territorial limits in space and time. The hydraulic constructions as irrigation canals have played a central role in the attempt to “dominate” the water resources and so control the territory. However and after some time, both the modernization of traditional irrigation as the promotion of new irrigation projects are called into question due to the rise of environmental demands and promoting governance as a mechanism favourable to agreements between stakeholders. In Catalonia, the irrigation management must deal both efficiency requirements as to the compatibility between consumptive and non-consumptive water uses well as the social legitimacy of projects that exceed sectoral interest. The situation analysis of Bajo Ter and Muga historic irrigation canals and the running project of Segarra-Garrigues irrigation canal emphasize the need to promote a territorial management model capable of integrating and legitimize different competing water views

The Social, Political, and Environmental Dimensions in Designing Urban Public Space from a Water Management Perspective: Testing European Experiences

Urban areas are increasingly experiencing extreme weather events, especially related to water (e.g., droughts, heatwaves, floods), which are devastatingly impacting infrastructure and human lives. Compact cities, conceived to create more robust, effective, and sustainable environments, are under pressure to increase their resilience by co-producing adaptive strategies mainly focused on the urban public space. However, public space design tends to face environmental challenges without sufficiently exploring their intersection with social issues (citizens living conditions and vulnerability) and political structures (governance). This contribution delves into how urban public space interventions are (not) moving towards achieving urban resilience in an integrated way instead of sectoral. A triple-loop approach has been developed and tested in ten urban public spaces in European compact cities in the last 25 years. The results report how most projects reinforce the social dimension by promoting citizen well-being through new quality standards in public spaces, excluding some citizenry’s vulnerable segments (immigrants, women, and disabled). The political dimension reinforces hard adaptation measures to manage water resources, although increasing attention is put on nature-based solutions, and most projects ensure participation processes. Finally, the environmental dimension is the most transversal by increasing land conversion, ensuring flooding mitigation, and enhancing adaptive capacity

Pesca marítima recreativa i conservació dels peixos litorals: el cas del cap de Creus.

En aquest article s'analitza l'impacte biològic de cadascuna de les modalitats de pesca recreativa (pesca des d'una embarcació, pesca des de les roques, marisqueig i pesca submarina) sobre les espècies costaneres del cap de Creus i es determina les característiques socioeconòmiques d'aquesta activitat d'esbarj

Low-power pedestrian detection system on FPGA

Pedestrian detection is one of the key problems in the emerging self-driving car industry. In addition, the Histogram of Gradients (HOG) algorithm proved to provide good accuracy for pedestrian detection. Many research works focused on accelerating HOG algorithm on FPGA(Field-Programmable Gate Array) due to its low-power and high-throughput characteristics. In this paper, we present an energy-efficient HOG-based implementation for pedestrian detection system on a low-cost FPGA system-on-chip platform. The hardware accelerator implements the HOG computation and the Support Vector Machine classifier, the rest of the algorithm is mapped to software in the embedded processor. The hardware runs at 50 Mhz (lower frequency than previous works), thus achieving the best pixels processed per clock and the lower power design
