Drought,social agents and the construction of discourse in Andalusia

Despite the severity of the last droughts in Spain, there has not been any significant shift in the current planning strategies, due to a significant resistance to abandoning traditional practices against this hydrological risk. To better understand the origin of this resistance, the changing role of the relevant stakeholders in the debate and the key issues, this paper is aimed at undertaking a discursive analysis of the information conveyed by the media in hydrological years 2004–2005 and 2011–2012, through the application of the software Atlas.ti.     

Monitoring morphological changes along the coast of Huelva (SW Spain) using soft-copy photogrammetry and GIS

This contribution deals with the use of different sources of data (field surveys with total station and GPS, air photographs and topographic maps) as well as their integrated digital treatment in a GIS context to quantify the morphological changes in a ridge of coastal dunes in the southwest of Spain. The results show very high and increm enting rates of foredune retreat significant losses of foredune surface and a clear negative sedimentary balance (lowering and inland migration) in its recent evolution (1979–1996). Two processes can explain this evolution: (1) marine erosion and (2) the reactivation of aeolian deflation. The combined use of GPS (code/phase) and soft-copy photogrammetry seem to provide the best for monitoring future changes.
