To apply the integrated approach to best effect, the level of catchment, river basin or sub-basin should be considered, where appropriate.

The most important gaps in knowledge concern : 1) transfer and degradation processes (a better understanding and quantification of the fundamental transfer processes by which dioxins and PCBs move between the different environmental media and of the degradation processes occurring within these media is needed); 2) bio-accumulation and bio-magnification processes; 3) domestic incineration of wood (there is an information deficit concerning the amount and the composition of wooden fuels used for room heating and cooking purposes); 4) reservoir sources (the contribution to human exposure, the behaviour and degradation processes and decon ...[+++]tamination methods require examination); 5) open uses of PCBs; 6) carry-over rates and transfer factors for dioxins and PCBs from soil and feed to animal tissues and products (milk, eggs).

River basins are considered as the management unit for water resources and each has a "Plan de Cuenca" (Basin Plan), whose main objectives are to achieve a highly satisfactory level of supply in quantity and quality, best possible use of the resources available through savings and more efficient management, the diversification of the resources in its origin and reduced vulnerability of water supply systems.

Ways of mitigating the impact of nutrient wastes that deserve consideration by Member States and private enterprises include: integrating aquaculture into coastal and river basin area management, placing production facilities in areas with good water exchange, using improved feed and feeding methods, and fallowing (site rotation of cages in order to speed recovery of the bottom layer).
