Water footprint and consumption of hydropower from basin-constrained water mass balance

Fewer Basins Will Follow Their Budyko Curves Under Global Warming and Fossil‐Fueled Development

“…However, an earlier study shows that movements in Budyko space in (some of) these basins follow spatial patterns of reservoir impoundment and agricultural expansion (D. Wang & Hejazi, 2011). Many other studies find that movement in Budyko space relates to specific signals of human developments such as reservoir impoundment (Jaramillo & Destouni, 2015; Levi et al., 2015; Sun et al., 2021), forestry (Jaramillo et al., 2018), environmental impacts on forests (Renner et al., 2013), to name a few. As such, the space‐for‐time substitution must be valid, at least in these cases of the scientific literature where movement in Budyko space relates to particular drivers and is based on observations.…”

“…To date, the interpretation of movement in Budyko space has been used for a large set of applications, such as to determine: (a) how hydroclimatic change manifests in different biomes (van der Velde et al., 2014), (b) hydroclimatic change global effects of water use and water footprint estimations (Jaramillo & Destouni, 2015; Sun et al., 2021), (c) the influence of forest characteristics on water yield resilience to climate warming (Creed et al., 2014), (d) hydroclimatic change and implications for land water management (Piemontese et al., 2019), (e) the existence of shifts in hydroclimatology (Heidari et al., 2021) and drought (Maurer et al., 2021), and (f) the hydrological effects of vegetation change (Z. Chen et al., 2021). Our study elucidates the implications of using CMIP6 outputs to recognize drivers of changes in water fluxes and water partitioning (i.e., the evaporative ratio) and its effects on applications of the Budyko framework for separation and identification of drivers and responses.…”

“…Nr. of Basins and Percentage Not Following Their Budyko-Curve Trajectories From 1901-1950to 2051-2100, Relative to 1901-1950 relates to specific signals of human developments such as reservoir impoundment Levi et al, 2015;Sun et al, 2021), forestry (Jaramillo et al, 2018), environmental impacts on forests (Renner et al, 2013), to name a few. As such, the space-for-time substitution must be valid, at least in these cases of the scientific literature where movement in Budyko space relates to particular drivers and is based on observations.…”

Distinctive Patterns of Water Level Change in Swedish Lakes Driven by Climate and Human Regulation

“…This is aligned with our findings showing that the mean annual DS in Sweden has been mostly decreasing since 1995 (DS AT = −3.8 cm/yr). Regarding the effects of regulation, the influence of water regulation schemes on water resources is not only bound to snow‐dominated areas but also evident in other world regions (e.g., Botter et al., 2010; Jaramillo & Destouni, 2015; Sun et al., 2021; Zamora et al., 2020). For instance, Xie et al.…”

Hydropower Scenarios in the Face of Climate Change in Ecuador

“…The International Renewable Energy Agency (IRENA) establishes that between 2010 and 2020, the global weighted average power factor for hydroelectric changed from 51% in 2015 to 46% in 2020 in commissioned projects, which shows that hydropower is losing efficiency by around 1% per year by the climate change affections around the world [28], [29]. Therefore, to standardize the term power factor throughout the document, it is defined as a measure of the efficiency of an electrical system because it represents the performance and energy used to transform it into effort [30].…”
