The study of the impact of vegetation on climate temperatures and hydrology is a new discipline.
This multi-disciplinary activity seeks to provide key notions about the role of vegetation and to give contextual results.
It is difficult to generalise results given the variability of various determining factors which are more or less wellknown.
The term "vegetation", for example, covers a wide diversity of species with different physical and physiological properties: resistance to drought and evapotranspiration, colour and albedo, density and leaf persistence, etc. Local meteorological conditions (sun, wind,and hydrology) vary significantly in the urban environment. Management also plays a major role which is complex to standardise and evaluate.
The impact of vegetation in a polluted environment is no longer questioned, but adaptability remains a question which requires a great deal of research.
Ecosystemic services are fundamental to the urban environment.Major cities must confront demanding environmental objectives which may sometimes seem contradictory, such as densification to limit urban spread, biodiversity maintenance, anticipating and limiting climate change, the reduction of greenhouse gases and providing a healthy and agreeable environment for the inhabitants. These issues must be taken into account at every level of urban spatial intervention and be monitored over time. Practically speaking, this requires constant interrogation about the relative roles of urban and vegetation forms. Unlike a botanical garden, our aim is not to register a maximum number of plant specimens in an encyclopedic manner. Rather, the aim is to carefully choose endemic plants or introduce exotic plants which have a great capacity for adaptation and can interact directly with our urban environment. We will specifically target medicinal plants, creating the possibility to reintroduce them and study them in an urban context.
