Visit to South Devon Coast and National Park upland moors (i.e. Dartmoor and Exmoor)

On Tuesday 19 November, my supervisor (Duncan Russel) and me made a long tour through Devon, which is in the south west of England, to visit possible sites which we will study as cases for the BASE project (i.e. the South Devon Coast and National Park upland moors). We first visited the South Devon Coast, and passed along Dawlish and Teignmouth. The coast here suffers from erosion, and the sandy beaches are nearly gone. There is a railway along the coast, which provides a double function being an infrastructure connection as well as a sea wall protecting the inhabitants behind it against flooding. Due to rising sea levels, and coastal erosion, the railway has become increasingly under pressure. The question rises what to do next? If the railway would be relocated more land inwards, there might be less incentive to maintain and preserve the sea wall; how will the houses be protected in future? Who decides about possible relocation of the railway? Which impacts may be expected if the railway stays or if it would be relocated? The sandy beaches along the South Devon Coast have typically attracted a lot of tourism. As the sandy beaches are eroding, there is also a question how tourism will respond to that. And subsequently, how the villages and towns which used to profit from beach tourism will respond. In our study, we will look into these kinds of issues. Here a photo of the coast at Dawlish (photos by Duncan Russel).

Flood risks for the villages and towns at South Devon Coast are also under influence of peak run-off from the stream upwards situated upland moors. The peat layer in the upland moors (i.e. Dartmoor National Park and Exmoor National Park) absorbs and then slowly releases water from precipitation; functioning as a sponge and naturally protecting the downstream areas from peak run-offs. This peat layer provides a habitat for specific flora and fauna. The landscape of the upland moors of Dartmoor and Exmoor is typically highly appreciated for its recreational value. Under influence of increasing temperature and intensive grazing regimes (by sheep, cattle and ponies), the peat layer of the upland moors is expected to decompose and shrink. When this peat layer becomes thinner it will be less able to hold water. As a consequence - together with events of peak precipitation - chances of flash floods are likely to increase. The peat layer may also decompose when agricultural uses increase in the National Parks of Dartmoor and Exmoor. Who are in charge of the management of this peat layer in the upland moors? Which adaptations or interventions may be developed to address the influence of climate changes (such as changes in temperature and precipitation)? Who would decide about these possible interventions and their implementation?
