Its goal is to contribute towards the integrated and sustainable implementation of the WFD.

After addressing the importance of the maritime sector as a whole, the position paper also highlights the fact that recreational use of European waters is also of huge economic significance.

As PIANC points out, the aims of the WFD in promoting sustainable water use are broadly supported by the port, harbours, navigation and dredging sector.

'However, ' says the position paper, 'the WFD also raises issues which are of fundamental importance to the sector and require urgent attention. If the objectives of the WFD are to be achieved in a sustainable manner - compatible with the reality of the maritime and inland waterways sectors - these issues must be addressed.'

The issues in question which the paper highlights include the wider environmental issues of the WFD; the need for clarity, consistency and transparency;

and the practical and economic implications of the WFD.

'The WFD could have potentially adverse consequences for the ports, harbours, the navigation and the dredging sectors, " said the paper. 'Early consideration must be given to the practical implications of the Directive, including possible constraints on activities and operations, increased costs, and delays or uncertainties.'

'Further, ' says the paper, 'the economic analyses need to include an assessment of the financial and economic implications of the WFD for port, harbour, navigation and dredging activities.'
