“…Ages of elevated lacustrine landforms on the southwestern Tibetan Plateau. Lake numbers: 44 = Nariyung Co (Li et al 1982); 45 = Chen Co (Li et al 1982); 46 = Dajia Co ; 47 = Peiku Co (Li et al 1982;Kong et al 2011;W€ unnemann et al 2015); 48 = Drolung Co (Kong et al 2011). bon dating of aquatic plant remains and/or biogenic carbonate is the spatial and temporal variability of the reservoir effect (Yu et al 2007b). This age offset is extremely large in some lakes (Mischke et al 2013), for example the Dalianhai Lake (Chen et al 2012) and Heihai Lake (Lockot et al 2015), and may have varied significantly within single lakes (Hou et al 2012).…”

Geomorphic evidence suggests that shorelines of 100–200 m above the modern lake levels were common across the Tibetan Plateau during late Marine Isotope Stage (MIS) 3. The timing of this lake‐level highstand is mainly based on radiocarbon ages. Problems surrounding the ages of lacustrine sediments at or beyond the limit of the radiocarbon‐dating method have created a need for alternative geochronometers. Chronological advances during the last decade have renewed interest in the timing of events beyond the limit of radiocarbon dating. Here, we synthesize published data for elevated lacustrine landforms of 48 lakes on the Tibetan Plateau, in order to provide a thorough perspective on the timing and pattern of lake‐level changes in this alpine area during the late Quaternary. The ages of these elevated shore features reveal a long‐term trend of relative lake‐level fall from at least MIS 5, instead of a peak in MIS 3, as previously thought. Dating lacustrine terrace sequences reveals that the rate of lake‐level fall ranged from ~1 to 3 mm a−1, comparable with that of related river downcutting across the plateau. Palaeoclimatic proxy records point to a sustained drying since the Last Interglacial, suggesting that long‐term aridification might be the culprit for this widespread and progressive lake‐level fall.

“…Paiku Co (85°35.12′E, 28°53.52′N, 4,580 m a.s.l.) is located at the source of the Menqu River Valley and at the northern foot of Xixiabangma Mountain in the central Himalayas (Wünnemann, Yan, & Ci, ), as shown in Figure . With a surface area of 270–280 km 2 which accounts for approximately 11.7% of the total area of the basin (approximately 2,400 km 2 ), Paiku Co is hydrologically closed with evaporation as the primary water loss pathway.…”

Glaciers and snow cover are important constituents of the surface of the Tibetan Plateau. The responses of these phenomena to global environmental changes are sensitive, rapid and intensive due to the high altitudes and arid cold climate of the Tibetan Plateau. Based on multisource remote sensing data, including Landsat images, MOD10A2 snow product, ICESat, Cryosat-2 altimetry data and long-term ground climate observations, we analysed the dynamic changes of glaciers, snow melting and lake in the Paiku Co basin using extraction methods for glaciers and lake, the degree-day model and the ice and lake volume method. The interaction among the climate, ice-snow and the hydrological elements in Paiku Co is revealed. From 2000 to 2018, the basin tended to be drier, and rainfall decreased at a rate of −3.07 mm/a. The seasonal temperature difference in the basin increased, the maximum temperature increased at a rate of 0.02 C/a and the minimum temperature decreased at a rate of −0.06 C/a, which accelerated the melting from glaciers and snow at rates of 0.55 × 10 7 m 3 /a and 0.29 × 10 7 m 3 /a, respectively. The rate of contribution to the lake from rainfall, snow and glacier melted water was 55.6, 27.7 and 16.7%, respectively. In the past 18 years, the warmer and drier climate has caused the lake to shrink. The water level of the lake continued to decline at a rate of −0.02 m/a, and the lake water volume decreased by 4.85 × 10 8 m 3 at a rate of −0.27 × 10 8 m 3 /a from 2000 to 2018. This evaluation is important for understanding how the snow and ice melting in the central Himalayas affect the regional water cycle.

“…due to the combination of tectonic, volcanic, and anthropogenic activities (Murwanto, 2014). Even though the lake (surface water) has strong correlation with climate, the shallowing of the lake is not only linked to local or global climatic variations, but also to non-climatic influences, such as tectonic activities, changes in local catchment morphology, and human activities (Coulthard et al, 2005;Dietze et al, 2010;Zhang et al, 2013;Wünnemann et al, 2015). Gomez et al (2010) stated that the hydrographic network in Borobudur was strongly disrupted by volcanic activities, generating an alternation of fluvial and lacustrine settings in the basin.…”

In 2015, the number of international tourists who visited Borobudur temple declined and did not reach the government target. It was because there was only one attraction in the temple. After visiting Borobudur, most of tourists move to another place such as Yogyakarta. They know about the temple, but not its past environment when the temple was built. The history and past environment of Borobudur temple could be developed as additional tourist attractions to make them stay longer in that area. Geological condition and the evidences of an ancient lake could be developed as tourist objects. It is very interesting and could be developed to educate visitors in geo-archeology. The aim of this research is to develop archeological (temple) tourism based on geology and past environment. Although many researches on geo-archeology have been done, the results which relate to tourism are still not widely applied yet. The methods used are secondary data analysis and a field survey to investigate the potential of tourist stop sites. The potential tourist attractions were determined by geomorphology, lithology outcrops, stratigraphy, environment, and accessibility. The result is ten stop sites which could be used to describe the paleoenvironment in Borobudur based on geosciences. These tourist objects could explain the environment in the past related to the temple reliefs and ancient human activities.
