Co-operative Approach in Water Catchments

Stakeholders:• Water management

authority

• Local water supplier

• Ch. of Agriculture

• Farmers spokesman

• Advisory service

Approx. 115 Co-operations

cover ca. 280.000 ha statewide

ca. 10.000 Farmers


Nr.: 7



NLWKN

The Co-operative Approach

• Free Advisory Service– Individual voluntary consulting service for

agriculture, forestry and market gardening

• Voluntary Agreements– Negotiation of Voluntary Agreements to implement measures for

groundwater protection

(Catalologue of Measures, e.g. catch crops, maize with undersown grass, N reduced crop rotation systems, new techniques for slurry application …)

• Efficiency Control


Nr.: 8



NLWKN

Lessons learned from the co-operative approach

in LS• Evident reduction of diffuse pollution by the co-operative approach.

• A sustainable water resources management needs a strong stakeholder participation.

•The implemantation of measures needs to be accompanied by an advisory service.

• Efficient monitoring strategy is necessary.

Forward looking strategies in view of EU WFD

Compliance with the requirements of the WFDmeans a reduction of diffuse pollution – 2010implementation of measures!

WAgriCo – ObjectivesBased on longtime experience in (ground-)water protection strategies in LSand the UK working on strategies for large scale implementation:

• Concepts for measure planning and implementation of measures to reduce diffuse pollution – based on a stakeholder approach

• Reduction requirements and impact of measures

• Concept for impact monitoring

• Implementation of integrated PoMs into Agri-Environmental Programmes

• Statewide and international transfer of experience from the pilot areas to enhance the stakeholder approach

Modelling the effects of measures implementationModelling the effects of measures implementation

1. Which are the target areas (individual hydro-

geological units as part of the gw-bodies)) for measure implementation in LS?

2. What reduction is required in the individual hydro-

geological units?

3. What can be achieved by optimum implementation?

Advisory Service

Impact Monitoring

Innovative Approach: • Funding an improved N-efficiency on farm level • Farmer is free in his decision for optimising strategies • Sound support by advisory service

Constraints• Data collation is very time consuming• Very heterogeneous database according to farmtype • Statewide comparable and reliable data base is

necessary according to EU requirements

Work will continue (e.g. standardisation)

Discussion to integrate this approach into an advisory measure


Nr.: 26



NLWKN

• Efficient measure planning and implementation should be accompa-nied by advisory service!

• Multi-level advisory service (basic, intensive)

• Assignment with initial and further training

NLWKN

• There is evidence for considerable reductions in NO3-concentrations by the application of the investigated measures. - But reduction targets are not achievable in all areas only with action-oriented measures (e.g. high percentage of arable land and high livestock density).

• Measures implementation has to be supported by qualified advisory services.

• Additional effects have to be considered:

- more intensive production due to increase of agricultural commodity prices

- expected reduction of N-surpluses due to new version of fertilizer ordinance in LS

• Additional efforts have to be made to achieve the targets of the WFD:

- increase of N-efficiency on the farms by consultancy and education

- innovative measures (e.g. „result-oriented measures“)

- technical solutions (e.g. „storage capacity”)
