In the last few years, parallel evolutionary processes in the socio-political, governmental and technological arenas have been providing new pathways for the collaborative generation, coordination and distribution of polycentric information. From a technological perspective, the proliferation of information and communication technologies (ICTs) has boosted the availability of information about our planet, along with its storage, processing and dissemination capabilities. The Worldwide Web and satellite and electronic sensors combined with smart phone technologies have also opened new means for social, political and scientific innovation. From a socio-political standpoint, the implementation of policies that encourage the reutilisation of data and protect the right to information of interested parties, together with growing social demands for transparency, have resulted in an increasing number of governments drawing strategies to open up public data. In this context, this paper addresses two main topics that we deem will be key drivers for improved water governance in the near future. First, it discusses new practices of collaborative and distributed generation and disclosure of information for water governance, and the resulting challenges and opportunities afforded by the use of ICTs. Second, it looks at the interplay between the uptake of ICTs and institutional frameworks, social dynamics and technological structures within which they operate to understand the extent to which ICTs affect decision-making processes and contribute to creating alternative spaces for the production of common services or alternative discourses. Despite the advances in open data policies, findings suggest that there remain significant challenges to take full advantage of the opportunities offered by ICTs, mostly derived from the structural conditions of existing models of decision-making, and information generation and management. It seems that the potentialities of ICTs as transformative tools are conditioned by the regeneration of the context within which decisions are made, that is, the democratic process itself.

Esta comunicación presenta los resultados de la investigación llevada a cabo para el desarrollo de un geovisor diseñado para la explotación y difusión de los datos de escenarios regionales de cambio climático para Andalucía. Este geovisor está basado en la generación de servicios interoperables OGC (Open Geospatial Consortium) de visualización. Este trabajo es fruto de la colaboración entre el Grupo de Climatología del Departamento de Geografía Física de la Universidad de Sevilla y la Consejería de Medio y Ordenación del Territorio (CMAOT) de la Junta de Andalucía. El conocimiento generado en términos de técnicas de geovisualización de BIG DATA espaciales ha sido transferido a la Red de Información Ambiental de Andalucía (REDIAM), con el objeto de poder ser aplicado a otros ámbitos de la información climatológica y ambiental. Los datos de partida proceden de los escenarios regionalizados para Andalucía a partir de técnicas de downscalling estadístico, a partir de la modelización (3 modelos CNMC3, ECHAM5 y EGMAN) y de los escenarios del IV Informe del IPCC (a1b, a2 y b1). Este trabajo ha supuesto la implementación de una base de datos espacial de gran volumen y difícil manejo que ha requerido el desarrollo de una nueva línea de investigación y desarrollos que permitiera el análisis y tratamiento de los datos acumulados para su explotación y difusión. El resultado de esta colaboración es un geovisor que permite consultar para la región, a una resolución de 200 metros, escenarios de temperatura media y precipitación para tres horizontes temporales (2011-2040, 2041-2070, 2071-2100) combinando modelos, escenarios y sus correspondientes indicadores de cambio. ; This paper presents the results of research carried out for the development of a GeoVisor designed for exploitation and dissemination of data of regional climate change scenarios for Andalusia. This GeoVisor is based on the generation of interoperable OGC display. This work is the result of collaboration between the Group of Climatology Department of Physical Geography of the University of Seville and the Environment and Spatial Planning Administration of the Andalusian Government. The knowledge generated in terms of techniques geovisualization BIG DATA space has been transferred to the Environmental Information Network of Andalusia (REDIAM), in order to be able to be applied to other areas of the climatological and environmental information. The input data come from the regionalized scenarios for Andalusia from techniques of statistical downscalling, from modeling (3 models CNMC3, ECHAM5 and EGMAN) and scenarios IV Report of the IPCC (A1B, A2 and B1). This work has involved the implementation of a spatial database of high volume and difficult handling has required the development of a new line of research and development that would allow the analysis and processing of data accumulated for exploitation and dissemination. The result of this collaboration is a GeoVisor that provides access to the region, at a resolution of 200 meters, scenarios average temperature and precipitation for three time horizons (2011-2040, 2041-2070, 2071-2100) combining models, scenarios and corresponding indicators of change.
