“…However, the typically high water quality found in forest headwater areas is negatively affected by the phenomenon of acid rain, when the atmospheric acid deposition (the airborne emissions of sulphur and nitrogen) increased due to the forest canopy area and roughness [22]. Acidification has probably affected aquatic ecosystems of the Jizera Mountains since the 1850s [15,17,31]. Atmospheric deposition reached its peak in the late 1980s and caused the widespread acidification of fresh water sources.…”

“…From 1984 to 1988, mature spruce stands (showing a 30% defoliation) were harvested by clear-cutting followed by reforestation with coniferous stands again. After the clear-cut, grass-dominated Junco effuse and Calamagrostietum villosae became a new dominant community there [17]. Through reforestation, in the 1990s, several exotic species (blue spruce-Picea pungens, black spruce-Picea mariana, etc.)…”

“…Atmospheric precipitation inputs at the Jizerka catchment are affected by both elevation and vegetative canopy [17]. Therefore, the hypsometric method was used to extrapolate point observations of gross precipitation, canopy throughfall, and the atmospheric deposition of acid components (sulphate, nitrate, and ammonia).…”

“…Evidence of water quality deterioration on a global scale during the last century has been associated mainly with poor watershed management [13,14]. In downstream areas, water quality has deteriorated mostly due to pollution at point sources, but headwaters are affected predominantly by large-scale air pollution (emissions of SO 2 , NO x , and NH 4 ) and subsequent atmospheric acid deposition [15][16][17].…”

In headwaters, snowmelt affects the replenishment of water resources as well as the occurrence of natural hazards. The environmental impacts of snowpack were analysed in a small forest catchment (Jizera Mountains, Czech Republic) in the context of forest dynamics, atmospheric deposition, and climate, 1982–2021. Snowmelt dominates in March–May with 41% of the long-term annual water yield; however, there is also seasonal acidification of stream water. Forest clear-cutting together with air pollution control has contributed to a decrease in the acid atmospheric load, but, in the spring, streams’ pH is often below the environmental threshold of 5.3. Snowmelt volumes did not show significant transformation with forest canopy and do not affect summer low flows. Peak flows in the springtime do not exceed summer flash floods (frequencies up to 0.13 against 0.02). Mean annual air temperature is increasing by 0.26 ± 0.08 °C per decade with more intensive warming (0.64 ± 0.1 °C per decade) in the winter season. The seasonal reduction in snowpack duration and maximum snow water equivalent (5.5 ± 1.2 days and 34 ± 8.6 mm per decade) corresponds with the largest drop in snow cover duration reported in zones of seasonal temperatures ranging from −5° to +5 °C.

“…Water availability and its conservation are among today's top global concerns (Křeček & Haigh, 2019;Li et al, 2021), and upstream areas play strategic roles in the water conservation of complex and dynamic landscapes (Booij et al, 2019;di Matteo et al, 2017;Křeček et al, 2021;Marhaento et al, 2018). Upstream areas consider playing a pivotal role in recharging groundwater (Irawan et al, 2009;Zheng et al, 2019), mitigating flood occurrences while maintaining river discharge persistence (Marhaento et al, 2018;Nugroho et al, 2013;Suryatmojo, 2015), and providing multiple ecosystem services for locals (e.g., Nugroho et al, 2020).…”

Kawasan hulu daerah aliran sungai telah lama dianggap memainkan peran strategis dalam konservasi air pada lanskap yang kompleks dan dinamis. Sementara banyak studi telah meneliti pentingnya upaya konservasi air, studi yang berfokus pada pengelompokan niat penduduk untuk terlibat dalam inisiatif konservasi air di hulu daerah aliran sungai masih belum banyak dipelajari. Untuk memahami bagaimana warga mengelompok, kami mengklasifikasikan warga di dua desa (Cibeusi dan Sanca) berdasarkan pendapat mereka yang khas terhadap variabel Theory of Planned Behavior (TPB), yaitu sikap, norma subjektif, kontrol perilaku yang dipersepsikan, niat perilaku, dan perilaku terhadap inisiatif konservasi air. Secara total, 200 kuesioner yang dapat digunakan dalam analisis telah diambil. Hasil penelitian menemukan bahwa warga dapat dikelompokkan menjadi dua kluster yaitu “pendukung konservasi air” dan “pendukung pasif”. Pendukung konservasi air dicirikan dengan kesepakatan yang tinggi pada semua variabel TPB, sedangkan pendukung pasif adalah sebaliknya. Temuan ini menegaskan bahwa persepsi masyarakat tidak homogen, tetapi merupakan kelompok individu yang memiliki pemikiran berbeda. Lebih lanjut, studi saat ini berimplikasi bahwa pengelola sumber daya air harus menyadari fakta bahwa masyarakat dapat dikelompokkan ke dalam kelompok yang berbeda berdasar pendapat dan kepentingannya masing-masing. Rancangan kebijakan, strategi, dan intervensi yang efektif harus dirancang sesuai dengan kelompok yang berbeda tersebut. ABSTRACTUpstream areas have long been considered to play strategic roles in the water conservation of complex and dynamic landscapes. While earlier studies have examined the importance of water conservation efforts, studies that focused on clustering residents’ intention to engage in water conservation initiatives in the upstream areas remain understudied. To understand how residents are clustered, we classify residents in two villages (Cibeusi and Sanca) based on their distinctive opinions of the Theory of Planned Behavior (TPB) variables, i.e., attitudes, subjective norms, perceived behavioral control, behavioral intention, and behavior toward water conservation initiatives. In total, 200 usable questionnaires were retrieved. The study finds that residents are clustered into two clusters named water conservation supporters and passive supporters. Water conservation supporters are characterized by high agreement on all the TPB variables, while passive supporters are the opposite. These findings confirm that communities are not homogenous but constitute a distinctive group of like-minded individuals. Furthermore, the current study implies that water resource managers should be aware of the fact that residents are clustered into distinct groups with their own opinions and interests. The design of effective policies, strategies, and interventions must be arranged according to those different groups.
