Water resources and land use planning systems in Portugal—Exploring better synergies through Ria de Aveiro
The paper discusses the relevance of a stronger articulation between land use and water resources systems to enhance the success of the Water Framework Directive. Using article 11 of the WFD, this paper assess (i) how the Spatial Planning and Urban Development Law as well as the Portuguese Water Law converge to promote better integration of water resources into spatial planning, (ii) how their prospects are developed at the regional basis, namely through the Regional Spatial Development Plan and River Basin Management Plan, and (iii) how these are prepared to inform other planning instruments at the local level. It shows through a spatial analysis of the regional land-use plan and the river basin plan as applied over the Ria de Aveiro estuary area, the conflicts and opportunities for stronger synergies. The paper concludes with a critical analysis of the integration of the spatial planning and water resources planning systems in Portugal, and reveals new insights and challenges for more productive synergies between these systems.
