Taiwan's rapid economic and industrial growth has put enormous pressure on its natural environment. This is especially visible in the coastal zone, where risks such as sea-level rise, coastal erosion, land subsidence , and flooding threaten the already vulnerable ecosystems. Ecosystem-based disaster risk reduction (Eco-DRR) is a management strategy...

Caota Sand Dunes Geopark was established in June 2020 and conserves a landscape of coastal sand dunes at the Taoyuan coastline. This is the first geopark in Taiwan to promote the value of coastal dunes, recognizing their ecological value and their protection function in the face of climate change. This geopark has been actively promoted and attract...

Coastal erosion is a common issue and has increasingly become one of the stark challenges along the Vietnamese coastline, in the age of global climate change. Large parts of the coast have already been eroded over the past decades and exacerbated by climate change effects, coastal erosion remains a serious threat to coastal habitats and residents....

Vietnam attracts many tourists owing to its unique and diverse geological landscapes. The Vietnam tourism development strategy until 2030 sets a target to make tourism a more sustainable economic sector, in which the advantages of natural resources and development of a variety of tourism products are promoted. Binh Thuan province in central-south V...

Both natural and anthropogenic forces could play significant roles in coastal erosion in Western Taiwan and Central Vietnam's coastlines. Intensive socio-economic development, sea level rise, more frequent and strong intensity of disasters are predicted to occur in a future of global climate change, which poses an urgent need for coastal hazard man...

Coastal environments are deteriorating worldwide due to a combination of human activities and natural stressors, such as land-use change, coastal erosion, sea level rise, pollution, etc. These degraded environments are vulnerable and can become a driver for disaster risk. As a countermeasure to these challenges, Nature-based Solutions (NbS) gain mo...

Vietnam is a country that is heavily affected by global climate change, with the coastal zone and low-lying river deltas being especially vulnerable. The coastal zone has rapidly evolved over the past few decades, as coastal tourism and other social-economic developments and industries all seek fortune and exploit resources in this area. Along w...

In this paper we present new data on tsaganomyid species from the Oligocene of Mongolia. This group of rodents, endemic to Mongolia, China, and Kazakhstan, is not well known. In the context of the well-dated sediments from the Taatsiin Gol and Taatsiin Tsagaan Nuur, Valley of Lakes, we were able to establish their occurrence precisely. We present a...
