Comparing cultural ecosystem service delivery in dykelands and marshes using Instagram: A case of the Cornwallis (Jijuktu'kwejk) River, Nova Scotia, Canada

摘要: Abstract Climate change and sea level rise threaten coastal areas around the world. In Bay of Fundy area Canadian Maritime Provinces, there are 364 km dykes protecting 32,350 ha drained agricultural land. The Nova Scotia Department Agriculture is in charge dyke maintenance on its coast, making decisions about which to reinforce for new climate conditions, realign (shorten), simply abandon. Decision-makers need better understand how people value use dykeland compared with marsh ecosystems they replaced, will return if abandoned or realigned. Cultural ecosystem services (CESs) refer nonmaterial contributions from nature human beings' subjective psychological aspects that affect their quality life. We analyzed CESs delivered by dykelands marshes Cornwallis (Jijuktu'kwejk) River using 4 months Instagram data. results show two different portraits: 1) were more associated aesthetics, recreational use, social relations, female users; 2) (particularly a restored freshwater wetland study area) used males locals artistic educational value. Foreshore salt largely unmentioned dataset may indicate did not consciously benefit this ecosystem. Social media data valuable providing large-scale quantitative understanding land cover/land alternatives supplement other in-depth analysis, while having limitations regarding noise user bias, as well concerns ethical issues ongoing accessibility.
