Indicator yet to be developed for food availability at different trophic levels. The year in which this environmental objective is expected to be achieved has not yet been determined. Therefore, '999912' is reported for 'Timescale'. Closure of Frisian Front for all fishing (2.8%) (North Sea Agreement 4.40). Further consultation between the fishing sector and NGOs to determine whether there are further possibilities for establishing no-fishery zones within the areas closed to bottom-disturbing fishing (North Sea Agreement 4.39) Understand changes in trophic level relationships and their impacts (MONS, 2030). If necessary, take additional measures based on lessons learnt (after 2030).

Indicators under development: Hydrographical conditions indicator (D7); Phyto plankton composition further development See also environmental target 5.3 indicators, nutrient inputs and abstraction: Year-round nutrient concentrations (N total and P total). Concentrations of chlorophyll a Primary production (gC/m2/y). In EIA and licensing, consider effects of mitigation through site selection and design of wind farms and other initiatives that may affect stratification. Research through Wozep and OSPAR (2030).

Indicators under development: Total nitrogen load from the rivers Concentrations of nitrogen (winter DIN) and chlorophyll a in WFD coastal waters. (NL-D5C1-KRW-2023) Concentrations of nitrogen (winter DIN) and chlorophyll a in river plumes (OSPAR assessment areas) (winter-nutrient-concentrations-qsr23-ospar) and (chl-a-concentrations-qsr23-ospar) River basin management plans 2022/2027 After implementation of WFD measures, determine in OSPAR context the remaining task and its action perspective for chlorophyll a concentrations in river plumes; this serves as input for the 2028 RBMPs. Nitrates Directive Action Programme Implementation plan of OSPAR's North-East Atlantic Environmental Strategy 2030 (NEAES). Progress D5T1 (2018): The updated environmental target also focuses on reducing nutrient inputs, but with the aim of lowering chlorophyll a concentrations in coastal waters.

Indicator under development: total nitrogen load at border measuring points. The year in which this environmental objective is expected to be achieved has not yet been determined. Therefore, '999912' is reported for 'Timescale'. NL is putting this on the agenda in international river commissions.

Indicators under development: Year-round nutrient concentrations (N total and P total). Concentrations of chlorophyll a Primary production (gC/m2/y). Studies for EIAs and permits for new activities. An assessment framework may be developed for this purpose, e.g. in relation to choice of location and level of nutrient extraction or input.

Indicator under development: Total nitrogen load OSPAR identifies which interventions can contribute to retention, e.g. through deployment of nature-based solutions (2030). Implementation after evaluation.
