Dissemination of these BMPs is executed through information, advice and training. Implementation measures of the BMPs are part of a proposal for sustainable reductions of point sources. Surveys of stakeholders and farmers in six pilot areas have been conducted to understand the level of awareness which exists in the various countries and to evaluate various elementsto propose a strategy to avoid point sources. Key elements for a sustainable strategy are: Changes in operator behaviour, improvement of technical and infrastructural status. Technique and infrastructure are seen to be the enablers. Key technical / infrastructural requirements need to be enforced to ensure that an implementation of Best Management Practices can be performed (among others most obvious is the need for rinsing water tanks). The challenge is to change operator behaviour. Here information,advice and training are considered the key measures. To reduce point sources the awareness and necessary monitoring processes need to include all operators in a water catchment area. The TOPPS project can be seen in the context of the political initiatives related to the thematic strategy and the Water Framework Directive. 收起
