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.

Définition
Sens technique

Expression inventée sur le modèle de la Trame Verte et Bleue, appliquée à la continuité écologique des sols. Largement ignorés pendant de nombreuses années, ces derniers sont pourtant essentiels au fonctionnement des écosystèmes. Ce terme désigne le réseau écologique en profondeur, à préserver et restaurer.

Artificialization of soils

Sens commun

Transformation d'un sol à caractère naturel ou agricole par des actions d’aménagement, pouvant entraîner son imperméabilisation totale ou partielle.

d'après Ministère en charge de l'environnement, OFB et PLanete-info
Sens technique

Phénomène qui consiste à transformer un sol naturel, agricole ou forestier, par des opérations d’aménagement pouvant entraîner une imperméabilisation partielle ou totale, afin de les affecter notamment à des fonctions urbaines ou de transport (habitat, activités, commerces, infrastructures, équipements publics…). En France comme dans d’autres pays, du fait de l'étalement de notre urbanisation et de nos infrastructures, l'artificialisation des sols augmente.

Cette réduction est préjudiciable à la biodiversité, au climat et à la vie terrestre en général : Accélération de la perte de biodiversité ; Réchauffement climatique ; Amplification des risques d'inondations ; perte de productivité agricole ; Accroissement des dépenses liées aux réseaux (routes, électricité, assainissement) ; Ajout d’autre nuisance à la biodiversité (nuisance…

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".

Buffer zone

Updated on 04/07/2018
Définition
Sens commun
Strip of land between cultivated areas and a natural habitat, arranged to limit the effects of agriculture on this habitat (e.g. an area developed on the banks of a river to protect the riverine habitat and limit inputs of soil, nutrients and pesticides into the waterways).

Groundwater recharge

Updated on 13/07/2018
Définition
Sens technique

According to the hydro-geological meaning, a water volume supplying an aquifer over a given time. Rainfalls are mainly recharging groundwater. Unconfined groundwaters are recharged rather fast at each rainfall event. The rise in water levels and rainfall events are observed on a piezometric curve.

Elevation of the piezometric record

Updated on 13/07/2018
Définition
Sens technique

Elevation defined either in NGF level (French levelling network) or in relative depth. The NGF level, established under the control of the National Geographic Institute (IGN), is the reference. NGF can indeed express altitudes in one and unique reference system, i.e. as compared to the same and unique fundamental point (or "origin-zero" or point zero). The "0" level is the average sea level in Marseilles. This point is used to determine the altitude of any other point. The elevation of the piezometric record can also be expressed in relative depth with respect to the benchmark of the

Piezometric record

Updated on 13/07/2018
Définition
Sens technique

The piezometric record is the collecting of the evolutions in time of the monitored groundwater level or piezometric level (see piezometric level). It consists of measurements that link the water level to a given date. Depending on the variability of groundwater level, the measurements are more or less close in time. The measurements obtained are positive or negative with respect to the measurement benchmark: they are positive when the groundwater level is below the benchmark measurement (the most common cases) and negative in the opposite case (artesian wells). Artesian: a well is artesian when the water is gushing. A record is represented by a curve which is time-slotted to be stored in a succession of points, each point representing a groundwater level at any given time. Points are linked to each other by means of a code that indicates whether a point is related to the preceding point in time. If the point is not related, it is then the initial point of a new part of the record…

Piezometric level

Updated on 13/07/2018
Définition
Sens technique
Level reached by water at one point and at a given time in a pipe reaching the groundwater sheet. The piezometric level can be transferred to a piezometric map. Some non-operated wells are used to measure this level, they are piezometers or observation wells. This level corresponds to the groundwater pressure; it is usually indicated in NGF metres (French Surveying and Levelling). When this level is above ground level, the groundwater is called artesian: water is gushing out. The piezometric maps established with all measured data give a graphical representation of the groundwater surface and can track its evolution over time and identify its direction of flow.

Groundwater ridge

Updated on 13/07/2018
Définition
Sens technique
Groundwater divide. Line at zero flow (no flow) between two adjacent groundwater basins. On each side of this ridge, the values of the measured piezometry (see this term) are lower than those measured (or estimated) on the ridge.
