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.

Electric fishing

Updated on 04/12/2018
Définition
Sens commun

Method used to evaluate the abundance of fish species in a portion of a stream and to precise the different populations. It consists in the creation of an electric current which attracts fish. Then, paralyzed by electricity, they rise to the surface, which helps their identification and counts. After a little while, fish are free to circulate in the stream again.

Marine Environment Action Plan (PAMM)

Updated on 04/12/2018
Définition
Sens technique
Planning document aiming to achieve the good ecological status of marine waters, adopted under the Marine Strategy Framework Directive. Each PAMM focuses on a marine sub region, a sea space that is homogeneous in terms of ecological functioning. It consists of five elements, reviewed every six years: initial assessment of the status of the marine sub-region, definition of the good ecological status to be achieved, environmental objectives to achieve good ecological status, monitoring programme for assessing the status of marine waters, a programme of measures including the actions to be implemented to meet the environmental objectives and thus achieve good ecological status. Adopted by the Coordinating Prefects of the Marine Sub-Regions, the PAMMs, during their implementation process, organise a consultation with the stakeholders of the maritime and coastal world, through the maritime councils of the sub-regions (CMF), as well as a public consultation. In metropolitan France, four sub-regions are covered by a PAMM: the Channel-North Sea, Celtic Seas, Bay of Biscay and the Mediterranean Sea.

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.
