Climate change (CC) is characterized by rising temperatures, which alters the natural water cycle due to the disruption of the water balance (Gaines, 2016). Simultaneously, impervious surfaces resulting from urbanization process contributes to both water dysfunction (limited infiltration and increased runoff) and the urban heat island formation, causing thermal discomfort to residents (Yu et al., 2017). To adapt cities to the effects of CC, planners encourage the implementation of solutions such as alternative water management techniques, provision of green-blue infrastructure and pervious surfaces or architectural design for buildings, all of which may reduce high temperature and regulate water flows (Kabisch et al., 2017).
Spatial planning documents are capable of driving the use of adaptation solutions. In France, through the Local inter-municipal Urban Plan (PLUi), communities attempt to frame urban development to be consistent with their political project and the national sustainable development objectives (Dameron, 2018). However, as the PLUi offer leeway of interpretation to both building project owners and planning and building permits instructors, local authorities are not always certain that the outcome will match the initial intentions. To best achieve their stated objectives, planners must evaluate ex ante the effectiveness of their document. To assist communities in this process, the MANIPUR project is developing a PLUi evaluation method that combines content analysis, multi-criteria spatial analysis and hydro-climatic modelling (Molines et al., 2020).
In this communication, we will present our first results on the creation of a semi-automated method, specifically the proposition of an adaptation solutions typology suited to the rules of a PLUi and translated into a GIS spatial analysis. The main spatial planning document of Nantes will be used to illustrate the application of our method, so as to analyze its capacity to integrate CC adaptation solutions.
