    Coastal areas are considered as one of the most vulnerable and dynamic environments onearth. Besides more than 50 % of the world population lives along the coastal fringe and the tourism has grown very fast. Often human settlements have developped without much respectto the dynamic coastal processes. This is pointed out by an overview of the characteristics of coastal areas. Thus for example man didn’t 't and doesn’t 't take very much in account the consequences of the rising of the sea level. At this moment man experiences several problems, which he actually induced himself.The issue of coastal erosion is discussed. In a reaction to the phenomenon of "coastalerosionman has (especially in the last decades) used a lot of coastal defence techniques.These techniques are reviewed and evaluated There is a distinction between the hard (e.g. seawalls, groynes, ...) and soft coastal defence structures (e. g. beach nourishment). The advantage of the soft techniques is that the damage they do to the coastal dynamics and the ecology are not so radical as the damage the hard techniques do. When defining the mostappropriate technique, priority is of ten given to the economic aspects and touristim, rather than to beach dynamics and safety of the coastal area. In order to prevent this and to realize asustainable coastal defence management, it is suggested to incorporate the coastal defence in integrated systems of Coastal Zone Management (CZM).At last the concept of CZM is explained en the CZM-techniques are discussed This illustrates the tact that the holistic approach and the variety of techniques (especially EIA and CZM- plans) in CZM are very suitable for coastal defence management. Nevertheless, looking to the future, one should take care that in the multiplicity of interests in the coastal area (and CZM) the natural dynamic processes play a central role in the management.
