“…Additionally, when exposed to different environmental conditions, ecosystems may adapt their behavior by reducing or increasing their water use to the water availability (Zhang et al, 2020). Similarly, direct human interventions, such as the conversion of natural forests to fast-growing monoculture plantations in many parts of the world has significantly altered forests, making them more susceptible and vulnerable to disturbances (Schelhaas et al, 2003;Levia et al, 2020). However, humans also have the ability to positively influence the water cycle through vegetation, by promoting sustainable agricultural practices and integrated forest management with a simultaneous focus on biodiversity, recreation and timber production.…”

“…Under continued global warming, precipitation and temperature extremes are expected to further increase and the hydrological cycle is likely to further accelerate (Allen et al, 2010;Kovats et al, 2014;Stephens et al, 2021). In addition, natural land cover change and anthropogenic activities of land-cover change and land-use management can substantially alter a catchment's water balance (Brown et al, 2005;Wagener, 2007;Fenicia et al, 2009;Jaramillo and Destouni, 2014;Nijzink et al, 2016a;Hrachowitz et al, 2020;Levia et al, 2020;Stephens et al, 2020Stephens et al, , 2021. Considering the unprecedented speed of change, Milly et al (2008) declared that stationarity is dead and no longer should serve as a default assumption in water management.…”

Abstract. To predict future hydrological behavior in a changing world, often use is made of models calibrated on past observations, disregarding that hydrological systems, hence model parameters, will change as well. Yet, ecosystems likely adjust their root-zone storage capacity, which is the key parameter of any hydrological system, in response to climate change. In addition, other species might become dominant, both under natural and anthropogenic influence. In this study, we propose a top-down approach, which directly uses projected climate data to estimate how vegetation adapts its root-zone storage capacity at the catchment scale in response to changes in magnitude and seasonality of hydro-climatic variables. Additionally, the Budyko characteristics of different dominant ecosystems in sub-catchments are used to simulate the hydrological behavior of potential future land-use change, in a space-for-time exchange. We hypothesize that changes in the predicted hydrological response as a result of 2 K global warming are more pronounced when explicitly considering changes in the sub-surface system properties induced by vegetation adaptation to changing environmental conditions. We test our hypothesis in the Meuse basin in four scenarios designed to predict the hydrological response to 2 K global warming in comparison to current-day conditions using a process-based hydrological model with (a) a stationary system, i.e. no changes in the root-zone storage capacity of vegetation and historical land use, (b) an adapted root-zone storage capacity in response to a changing climate but with historical land use, and (c, d) an adapted root-zone storage capacity considering two hypothetical changes in land use from coniferous plantations/agriculture towards broadleaved forest and vice-versa. We found that the larger root-zone storage capacities (+34 %) in response to a more pronounced seasonality with drier summers under 2 K global warming strongly alter seasonal patterns of the hydrological response, with an overall increase in mean annual evaporation (+4 %), a decrease in recharge (−6 %) and a decrease in streamflow (−7 %), compared to predictions with a stationary system. By integrating a time-dynamic representation of changing vegetation properties in hydrological models, we make a potential step towards more reliable hydrological predictions under change.

“…However, it should be noted that our experiments excluded the effect of lateral soil water ow from meltwater (Jiang et al 2021), which could reduce the source of water input and then might underestimate soil seepage. Future researches would be needed for quantifying those belowground hydrological, together with the grassland degradations and the resultant surface heterogeneity (Levia et al 2020).…”

“…However, previous researches are usually based on model simulations (Ge et al 2011;; few observational studies have been conducted in cold areas (Dai et al 2019;Yang et al 2016). Therefore, quantifying the soil seepage and its underlying environmental controls would further improve our knowledge of the ecohydrological processes and the estimations of water resources over alpine regions (Ireson et al 2013;Levia et al 2020).…”

The soil seepage is an important component for quantifying hydrological processes while remains unclear in high-altitude alpine meadows. The shallow soil seepage was continuously measured by an auto-logged micro-lysimeter (diameter = 30 cm, depth = 30 cm) from July 2018 to June 2019 in a piedmont summer pasture of alpine meadow on the Northeastern Qinghai-Tibetan Plateau. The results showed that all the shallow soil seepage events occurred during the non-frozen period from April to September and the accumulative amount was 106.8 mm, which consumed about 1/5 annual precipitation. The maximum and minimum monthly soil seepage was 30.7 mm in September and 1.0 mm in April, respectively. The binary Logistic model revealed that daily half-hour rainfall frequency (R2 = 0.37, individual explanatory power) and amount played significant roles in the daily soil seepage odds (R2 = 0.50). The best subsets regression analysis showed that the same-day rainfall amount (R2 = 0.59), the first 3-day rainfall frequency, and the first 4-day solar radiation accounted for 73% of variations in the daily soil seepage amount. Monthly soil seepage correlated with monthly rainfall frequency significantly (R2 = 0.74, p = 0.005). Our results highlighted that precipitation, including its amount and frequency, was the key determinant of the probability and amount of the shallow soil seepage in the piedmont summer pasture of alpine meadow. These findings would be helpful for improving predictions of the water budgets of piedmont alpine meadows.

“…Therefore, responsibility for this crisis does not fall on all of humanity equally, but on a specific way of living on this planetcapitalism -which is rooted in legacies of colonialism and ongoing unequal global relations and exploitation. This crisis of modernity becomes evident in innumerable instances, from the loss of forests in central Europe to climate change and monocultural plantations [49], to deforestation in Brazil (to make way for farmland) [35], oppression of minorities or women to racism, with roots in colonialism and slavery. It is perhaps the -at the time of writingstill ongoing global Covid-19 Pandemic which embodies this most vividly.…”

HCI’s Role in the Capitalocene: Lessons Learned from an HCI Master Course Across the Globe

Various concepts have attempted to capture the nature of the contemporary political-economic system of globalised capitalism and its disastrous consequences for the planet, including World System Analysis or the Capitalocene. Especially Decolonial thinkers see its roots in colonialism. The resulting modernity/coloniality structures many aspects of human life everywhere, including gender identities, relationships amongst humans and with nature. Technology plays a vital part, requiring reflections on how HCI researchers can react to these challenges. In a class of an HCI master program, we have attempted to jointly begin to understand HCI's role in the capitalocene by studying relevant concepts and empirically investigating specific local yet connected phenomena. With participants being distributed across the globe, we were able to study different shared yet locally specific phenomena inspired by multisited ethnography. In this paper, we report on the structure and experience of the class as well as our findings.
