  Abstract Camping is one of the popular recreational activities in mountain national parks. However, human activities inevitably cause impacts on natural resources, which includes vegetation loss, soil compaction and soil erosion (Hammitt and Cole 1998). The degraded environment also does harm to users experiences in return (Daniels and Marion 2006). In order to provide users with high quality camping experiences meanwhile avoid unacceptable impacts on the natural environment, monitoring and maintenance of campsites are necessary. Researchers in the field of recreation ecology have provided a sort of methods to monitor short-term and long-term changes in the condition of campsites. Methods to detect areal changes in bare ground and vegetation loss on campsites have been widely practiced in previous studies (Marion 1991, Wang and Watanabe 2019). Eagleston and Marion (2017) examined soil loss on campsites by comparing the current soil level around embedded rocks on site with the one recorded in past photographs through visual observation. Wang and Watanabe (2019) adopted Structure-from-Motion (SfM) photogrammetry mapping to obtain detailed profiles of the ground surface on the campsite where gully erosion was observed. However, no studies have been conducted to monitor the volumetric changes in ground surface on campsites that are suffering from soil erosion.This study aims to detect topographic changes of the ground surface and to quantify the volume of soil erosion on the current and former Kuro-dake campsites in the Daisetsuzan National Park (DNP) by SfM photogrammetry surveys.

  Title Efforts to improve sustainable tourism and environment sustainability: understanding from local peoples perspective in Sagarmatha National Park and Buffer Zone, Nepal Himalaya Type

  Abstract Nature- and culture-based tourism have been prevalent pathways for most of the worlds indigenous people (McLaren, 2003). Tourism has been a significant component of Nepals economy.Mountain tourism plays a leading role in Nepals tourism industry. Sagarmatha National Park and Buffer Zone (SNPBZ) is the third-largest visited protected area in Nepal (Ministry of Culture, Tourism, and Civiation, 2020). Rapid development of tourism has brought remarkable changes in SNPBZ. Spoon (2012) and Stevens (1991, 1993) discussed tourism impacts on cultural values and lifestyle of mountain residents. Nepal (2005)argued the unequal power structures and income differences induced by tourism in the park. Tourism is one of the essential elements to realize sustainable mountain development. To realize sustainable tourism, it is vital to enhance the well-being of residents and visitor experience in mountain regions. Therefore, this study aims to investigate the efforts made by local residents to improve sustainable tourism and environment sustainability in SNPBZ.

  Title Monitoring and predicting trail erosion in Daisestuzan National Park in Japan Type
  Year 2021 Publication The 10th MMV Conference: Managing outdoor recreation experiences in the Anthropocene – Resources, markets, innovations Abbreviated Journal

  Abstract Mountain trail erosion is one of the geomorphological phenomena, which is generally caused by surface water and human trampling. Mountain trail erosion is one of the most serious problems in many national parks of Japan. Such examples are observed on trails in Mt. Rausu-take (Shiretoko National Park), Mt. Rishiri-san (Rishiri Rebun Sarobetsu National Park), Mt. Daisetsuzan (Daisetsuzan National Park), and Mt. Miyanoura-take (Yakushima National Park). Volcanic ashes cover trails in most of these mountains, and snow remains until the time when many trekkers come. For these reasons, trails in these mountains are eroded rapidly and deeply. Therefore, it is important to conduct studies to predict further erosion. Mountain trail erosion has been traditionally studied by surveying cross-sectional changes at certain sites. The method of surveying cross section can be conducted quickly and simply for park managers to understand changing magnitudes of mountain trail erosion for a long period. In Japan, this method has been used mainly in Daisetsuzan National Park, and numerous data have been already accumulated in some trails. However, magnitudes of mountain trail erosion are understood in just two dimensions by this method. Furthermore, the largest limitation of this method is that the eroded/deposited area is understood only at the measured sites and does not produce the eroded/deposited volume of the entire trail segment with a certain length, which is more important for trail management. This study, conducted in Daisetsuzan National Park (DNP), Japans largest national park, has three objectives: (1) to show digital elevation models (DEMs) of the mountain trails including the surrounding ground surface, and to estimate the change of the eroded volume from 2014 to 2021; (2) to predict further erosion in the near future; and (3) to understand a relationship between the trail erosion and the number of trekkers.
