City visioning and the turn to community:The case of Derry/Londonderry

In the 1980s, urban re-imaging and place marketing were vital elements in the strategies of post-industrial cities aiming to redefine their role, make themselves more competitive and attract global investment and tourists. By the early 1990s, the questionable effects of trickle-down economics on deprived housing estates and the rediscovery of the 'community' as a social partner shifted both the substance and process of vision exercises. This paper examines the experience of building an input into a city vision that aimed to address social and ethno-religious segregation in Derry/Londonderry. Designing a consensus statement for a city that cannot agree its name, was wrecked by bloody violence and has its hinterland fractured by a contested international border, is a difficult and delicate process. The city had a population of 105 800 people in 1998, but is divided by the river Foyle between the mainly Catholic Cityside (to the north and west) and the mainly Protestant Waterside (to the south and east). The analysis connects with the literature on urban policy that emphasises the importance of argumentation and democratic debate in strategic planning and local regeneration (Forester, 1989; Healey, 1996). The paper concludes by arguing that strategies for 'listening' would help to shape a vision that could mobilise community interests around some common urban regional issues and help to promote social and ethno-religious polarisation as mainstream policy concerns.

Productive Synergies in the City

The chapter focuses on the development of sustainable growing infrastructure in the city at two scales. Firstly the development of a large-scale city wide fuel productive landscape through the development of algae arrays in Liverpool and their connection through urban agriculture systems to develop a closed-cycle food and energy system where waste is food and secondly a hyper-localised neighbourhood food production system in Salford UK that utilises a closed cycle aquaponic system to re-invigorate an urban food desert.

The author develops a three-part model for the implementation of urban agriculture based on hardware (the technological system), software (the biological components) and interface (the links to food and other social networks). The conclusion being that it is possible to develop urban agriculture in cities if their implementation is seen as a process, rather than a static design. Also that as the benefits of such systems are wider than purely the physical outputs of the system in terms of energy and food, and thus we should re-evaluate the purely economic model of appraisal to include these.

Neuromusculature of Macrogyrodactylus clarii, a monogenean gill parasite of the Nile catfish Clarias gariepinus in Egypt

Phalloidin fluorescence technique, enzyme cytochemistry and immunocytochemistry in conjunction with confocal scanning laser microscopy have been used for the first time to describe the nervous and muscle systems of the viviparous monogenean gill parasite, Macrogyrodactylus clarii. The gross spatial arrangement of muscle and associated cholinergic, peptidergic and aminergic innervations has been examined. The central nervous system (CNS) consists of paired cerebral ganglia from which emanate three pairs of longitudinal ventral, lateral and dorsal nerve cords, connected at intervals by transverse connectives. The CNS is better developed ventrally than dorsally or laterally, and has the strongest reactivity for all neuroactive substances examined. Structural and functional correlates of the neuromusculature of the pharynx, haptor and reproductive tracts have been examined. Results implicate acetylcholine, FMRFamide-related peptides (FaRPs) and serotonin in sensory and motor function in this monogenean, although confirmatory physiological data are obviously required.
