From the napoleonic cadastre to the ecological network "trame verte": the destiny of small suburban wetlands in the Nord-Pas de Calais region (France).

Abstract : The literature on wetlands mostly concerns a limited number of “emblematic” natural spaces and neglects the existence of a large number of small wetlands, which are rarely mentioned when not outright forgotten. The needs of the regionnal planning in the urbanized regions modify appreciably the outlook of land planners on the latter areas, because they become the support of projects which fit within the framework of the Sustainable development.
This situation calls for a renewal of classic approaches and analytical tools, such as used in the context of the National Research Programme into wetlands. Through the examples of the Guînes marsh, the Sensée valleys and the Haute Deûle (Nord-Pas de Calais), the point is less to characterise and circumscribe wetlands, and to understand how they work, than to define and examine the human interventions, past and present, and their effects on spaces and landscapes. Research was therefore articulated around two main investigations:
- the first is a historical study of the successive states of the landscape and of the relationships between society and its environment. The approach consisted in reconstructing past land covers from archival documents and aerial photographs,
- the second is a study of what is currently at stake in wetlands and how they are being appropriated by local and regional public policies.
Those marshes used to be characterized, until recent time, by contradictory evolutions, their present integration into the regional urban landscape is gradually erasing their differences and could compromise their future as natural spaces. In the long run, what is the possible evolution of these suburban wetlands?
