Nature based Solutions (NbS)

Updated on 21/09/2020
Définition
Sens commun

Les Solutions fondées sur la Nature (SfN) sont les actions qui s’appuient sur les écosystèmes afin de relever les défis globaux comme la lutte contre les changements climatiques, la gestion des risques naturels (inondations, sécheresse, submersion marine), la santé, l’accès à l’eau, la sécurité alimentaire…

Les SfN visent à protéger, restaurer et gérer de manière durable les écosystèmes : la préservation des forêts, les rivières en bon état, la restauration et  le fonctionnement des zones humides, tout concourt à agir au plus près du terrain (actions locales pour un objectif global). Il est impératif que la société adopte une combinaison de solutions inspirées par la  nature, dérivées de la nature et fondées sur la nature : Il s'agit bien d'intérêt mutuel. La nature y gagne, et les territoires qui prennent ainsi soin des cycles naturels, du bon état des milieux ont aussi tout à y gagner.

En effet, des écosystèmes sains, résilients, fonctionnels et diversifiés fournissent de nombreux services écosystémiques et permettent donc le développement de solutions au bénéfice de nos sociétés et de la biodiversité, dans le cadre des changements globaux.

Master plan for urban planning and development

Updated on 04/07/2018
Définition
Sens technique
Planning document with a regulatory purpose setting out basic guidelines for an agglomeration and harmonizing State programmes as well as those of local authorities, public institutions and services. The master plan for urban planning and development (SDAU) is thus a coherent framework for action for urban planning and the restructuring of urban areas. In the Urban Planning Code, the expression "the Master Plan for Urban Planning and Development" was replaced by the "Master plan".

Flood warning

Updated on 08/04/2020
Définition
Sens commun

Warning issued in advance by the departmental flood forecasting services. In the event of heavy rainfall or hydrological alert, a flood warning is sent to the Prefect, who then alerts the mayors of the catchment areas concerned.

Source
according to OFB
Sens technique

Warning issued in advance by a special state service (flood forecasting service). In the event of a rainfall or hydrological alert (triggering when thresholds are exceeded), the flood forecasting service offers the Prefect the alert of the mayors of the watersheds concerned. As a severe overflow flood, the flood warning service broadcasts, for prefects and mayors, hydrological situation bulletins and information on the evolution of water levels . In 1994, 54 flood warning services monitored 16,000 km of waterways in France using automated measurement networks.

Dam release

Updated on 06/09/2018
Définition
Sens technique
Operation to lower water level and increase outflow rates to discharge some of the sediment retained by a dam. A dam release consists in opening the gates, thus limiting the silting of the dam reservoir and the risk of flooding. This operation, although common in the management of harnessed rivers, can have adverse effects on the downstream environment (decrease of oxygen levels in water, obstruction of fish gills by suspended solids, etc.).

Groundwater/river exchange

Updated on 06/09/2018
Définition
Sens commun
Exchange of water in one direction or the other between an aquifer and a river. Depending on the level of the water line, and on the season, groundwater feeds the river or is fed by it, particularly during floods. In the case of karst, these relationships are important and localised.

Silting

Updated on 06/09/2018
Définition
Sens technique
Deposit of fine sediments made of rock particles and silt or clay. Siltation is a form of sedimentation with mud. Streams carry a few million cubic meters of sediment each year. Their deposit causes the silting of these rivers, canals, and bodies of water. This quite natural phenomenon is accentuated by a flat topography, low flows, erosion processes, as well as industrial and urban discharges.
