Substantial urban development (which has accelerated the effects of climate change), water and air pollution, as well as erosive forces have reduced natural habitats along the coast of Lebanon to less than 20%. One unique coastal ecosystem is the sand dunes, which once harboured rare and regional endemic plant species. Although sandy beaches currently occupy around 20% of the Lebanese shoreline, resorts, industries, commercial development and informal settlements have replaced the pre-existing, fragile dune ecosystems. The area under study stretches from the shores of Khalde in the south and the northern limits of Ouzai, the latter being an area dominated by informal settlements that have eroded and polluted the beach sand due to inadequate infrastructure. This has compromised and destroyed the highly specialised ecosystem and deteriorated its functions. Taking into consideration the beneficial functions and unique character of coastal sand dunes, this study presents a putative dune restoration plan that will essentially incorporate the nearby community in a self-sufficient, resilient landscape. A necessary change in the site's zoning plan, particularly in reference to land ownership and use, is needed prior to the implementation of the proposed restoration and integration program. Extensive environmental, spatial and social analyses allow the employment of several site-specific dune stabilisation techniques. The dune reinstatement methods will complement the establishment of a well-designed community in which human and environmental elements are integrated within designated spaces. These allocated interaction zones will act as a buffer between inaccessible dunes near the shore and the densely inhabited neighbourhood further inland. While the study focuses on the restitution of the coastal sand dune ecosystem, detailed design methodologies create a strategy for improving the living conditions within Ouzai. In light of the proposed design, the currently depreciated neighbourhood will experience more open space, enhanced infrastructure, cleaner air and a healthier environment.
