The project aims to respond to the problem of the degradation of municipal heritage and the rubbish and lack of cleanliness in urban spaces, involving the population and offering simple and sustainable alternatives. The implementation phase is based on two axes: environmental awareness-raising activities (health and environment); upgrading families' living spaces. The methodology is based on mobilising the resident population, from the perspective that their involvement in the various processes guarantees greater suitability of the changes made and an effective commitment to conservation and maintenance. This is how the figure of neighbourhood mediators came about. They are a response to problems identified in the area, especially those where traditional solutions have proved insufficient. This community mediation is interesting in that, by experiencing these problems themselves, they will be catalysts for behavioural change through their intervention.
