Under the Franco regime the Atlantic coast of Andalusia became the high-density hub of the Spanish chemical industry. The atlas of mortality by areas shows that something must be happening to cause the high cancer rates in the area. The atlas shows that, from Algeciras to Huelva, the densely packed factories must be considered as new, occasional cities that have arisen without taking into account the existing urban settlements. It is grotesque to come across formal strategies in their appropriation of public space; strategies stemming from the failure of urban planning to satisfy its needs and relieve the conditions of temporary shelters and irregular settlements built to accommodate temporary community groups. Permanent and transient citizens create entire communities, who demand living space for a diversity of methods; the occupation of vacant sites, recycled wasteland, self-builds; pinpointing and individualising neighbourhoods in order to preserve memories and rights and defining temporary constructions. Despite being considered “civil disobeyers” by the local government, these citizens have come together in a resistance movement as “urban guerrillas” who justifiably claim their rights on the planet, and oppose artificial urban growth processes, precariousness and the loss of public and natural space supported by municipal government policies. Meanwhile, these administrative solutions offer protection to the designers of urban spaces, to those who generate unlimited speculation and use green areas as industrial or building land in order to superimpose a new skyline to keep tourists and new “owners” happy. These governments also carry out a continuous “image clean-up” to try to justify their policies, replacing people’s cultural expressions with others that serve their objectives.
