Cromarty's society and economy are strongly dependent on water, however, social development has led to the destruction or pollution of many important water bodies in the Cromarty Firth area, one example being the catchment from Loch Eye to Nigg Bay in the north. Loch Eye and Nigg Bay as part of the most important habitats in the highland, supporting internationally important wintering populations of waterbirds, however, the direct discharge of sewage from surrounding farmland into the water bodies has led to poor water ecological status, causing negative impacts on both the natural environment and wildlife. On the other hand, because the site is located on the plain, flooding and sea-level rise due to climate warming are strongly threatening this area.
Because of the complex interactions between water, human society and natural environment, the project aims to enhance water ecology by creating resilient waterfronts that connect society with the environment. The purification capacity of the water bodies is enhanced by ecological interventions that gradually increase the ecological status of the water as it flows from Loch Eye to Nigg Bay across wetlands, buffer strips and salt marshes.
At the same time, wetlands and salt marshes increase the resilience of the coast, acting as a buffer and absorber in the face of flooding and sea-level rise, mitigating the effects of climate warming on the site. Furthermore, the project emphasizes the recreational function of the waterfront and increases the connection between society and the environment by attracting wildlife and visitors through a well-established blue network and green network.
