Bob Dylan once sang that he contained multitudes. So too does integration. More integrated planning of coasts and oceans has long been hailed as a goal and is seen as a pathway towards a more legitimate, cost-effective, equitable and sustainable planning of marine space. However, a reading of the literature indicates that many integration efforts have seemingly failed to reach their potential, and there is no clear understanding of what integration means or how we should best go about achieving it.The paper claims that this uncertainty partially stems from a unnuanced and static treatment of the concept, and a lack of recognition of the multitudes of integration. The paper argues firstly that fragmentation should not uncritically be seen as the antithesis to integration and as a negative property to be avoided. Secondly, there needs to be greater recognition of both the varying degrees of integration and the contextually dependent necessity of different degrees of integration. Lastly, it is more fruitful to see the multitude of nodes in the expanding ‘network of planning’ not as fragmentation, but as differentiation. Such an approach allows us to see integration as a mean towards more sustainable planning of coastal and marine areas, not end in and of itself.
