Marine Strategy Framework Directive

Updated on 25/02/2019
Définition
Sens technique
Directive 2008/56/EC of the European Parliament and of the Council establishing common framework and objectives for the protection and conservation of the marine environment by 2020. Member States shall assess the needs in the marine areas under their jurisdiction and develop their own strategies to achieve good ecological status of marine waters for which they are responsible. These strategies are designed to ensure the protection and restoration of European marine ecosystems and the ecological sustainability of economic activities linked to the marine environment.

Collecting system

Updated on 26/10/2022
Définition
Sens technique

Any system which, by measurement, observation or any other method, can acquire knowledge data on: aquatic environments, water resources and uses, pressures (and associated impacts) exercised on the environments and resources, and related economic data. It may be monitoring networks, surveys (water prices, economic activities), inventories (wetlands, lakes, flood-risk areas, protection perimeters ...), etc.

Ecological status

Updated on 13/07/2018
Définition
Sens technique
Assessment of the structure and functioning of aquatic ecosystems associated with surface waters. It is based on criteria called quality elements which can be biological (presence of living plants and animals), hydro-morphological and physico-chemical. The ecological status has five classes: very good, good, fair, poor and bad. For each type of water body, it is characterized by a deviation from reference conditions (conditions representative of surface water which is not or very little influenced by human activity). The "very good" ecological status is defined by very small differences due to human activity compared to the reference conditions of the type of water body considered. The "good" ecological status is defined by small deviations due to human activity compared to the reference conditions…

Ecological potential

Updated on 13/07/2018
Définition
Sens technique
Goal to be achieved by 2015 for artificial water bodies and heavily modified water bodies in accordance with the Water Framework Directive 2000/60/EC. The ecological potential of an artificial or heavily modified water body is defined with reference to the most comparable type of surface water bodies. Compared to the values of quality elements for the most comparable type of surface water bodies, the values of good potential take into account the artificial or heavily modified characteristics of the water body. The ecological potential has four classes: good, moderate, poor and bad. Meanwhile the chemical objective remains unchanged.

Quantitative status

Updated on 13/07/2018
Définition
Sens technique

Estimate of the balance between, on the one hand, abstractions and needs related to supply inputs to surface water, and on the other, the natural recharge of groundwater. The quantitative status has two classes: good and poor. Good quantitative status of groundwater is achieved when abstractions do not exceed the turnover capacity of the available resource, taking into account the necessary supply inputs to surface water ecosystems, directly dependent sites and wetlands.

Chemical status

Updated on 13/07/2018
Définition
Sens technique
Water quality assessment based on the concentrations of pollutants including priority substances in particular. The chemical status has two classes: good and poor. Good chemical status of surface water is achieved when the concentrations of pollutants do not exceed the environmental quality standards. Good chemical status of groundwater is reached when the concentrations of pollutants do not show any effect of salt water inflow, do not exceed the quality standards and do not prevent achieving the objectives for associated surface water.

Decree

Updated on 19/06/2018
Définition
Sens commun

Regulatory act signed either by the President of the Republic or by the Prime Minister. The decrees called "State Council decrees" can only be taken after collaboration with the Council of State. The decree is a statutory text issued by the executive power and intended to clarify the special terms and conditions for the application of a law passed by the parliament. It is most often complemented by implementation decrees.
