“…water resources, among others are becoming a great concern. For this reason, the changing climate is posing a great challenge to environmental water management (Capon et al, 2018;Murphy and Kitamirike, 2019) occasioned by unreliable rainfall (Mfitumukiza et al, 2020;Nyakaisiki et al, 2019). The main challenges relate to the demand and supply of water to the community.…”

“…The main challenges relate to the demand and supply of water to the community. For example, the changing climate is driving shifts in global patterns of water and consequently affecting water security (Capon et al, 2018;Egeru et al, 2019). Therefore, the government of Uganda is examining the climate change risks into water resources and supporting integration of climate change adaption (Murphy and Kitamirike, 2019;Mwebaze, 2018).…”

“…Due to the changing climate and environment, e.g. increasing population pressure, water scarcity, loss of wetlands, and soil erosion (Amanyire, 2018;Capon et al, 2018), water management has been zoned to facilitate the implementation of catchment management zones (Egeru et al, 2019;Murphy and Kitamirike, 2019). This is further recommended by Mwebaze (2018) who opined that water allocation should be based on management zones.…”

“…The surface and ground water hydrology of River Mpanga catchment like other water catchments are highly sensitive to the altered precipitation, warming, increased evaporation, sea level rise and altered snow melt projected under many climate change scenarios (Capon et al, 2018). Egeru et al (2019) have projected a net decrease of water resources base by 12.6% over the Nile Basin by 2040.…”

Different sectors globally are experiencing the impacts of changing climate and water resources are among them. This study was conducted with an aim of examining the community views regarding the effect of changing climate on water demand over the River Mpanga Water Catchment. The study employed a cross-sectional survey using 111 household interviews; 14 Focus Group Discussions (FGDs) and 27 key informants interviews (KII). This study considered 14 villages and employed a mixedmethods study design. The analysis was conducted using SPSS software to derive the descriptive statistics. Qualitative information was analyzed using content analysis to conduct an in-depth analysis. The study found that the main source of water is tap water (72.1%) and the main use of water in the study area is domestic water use. This study also found that, breakage in water supply especially during the dry season (10 out of 14 FGDs) and poor quality of water especially the tap water due to chemical treatment (11 out of 14 FDGs) were the major challenges of water the community faced. Additionally, this study observed that 15 out of 27 KII considered drought as a major threat and that the area had experienced decreases in rainfall amounts over the months of January and February. Therefore, this study recommends that the providers of domestic water should invest heavily in technologies for improving water quality and amount; ensure sustainable and equitable rationing of water during scarcity; and promote incentives for water harvesting.

“…A particular focus has been temperature, which is one of the most important factors controlling freshwater survival of salmon (Bartholow 2004, Alexander et al 2015, Martin et al 2017). The literature has expressed similar concerns (Olden and Naiman 2010), noting it is not sufficient in e-flow restoration to mimic natural flow regimes as we enter a future of changing natural baselines (Capon et al 2018). The challenge was succinctly framed in a study to promote both fish and hydroelectric production in the Mekong River (Sabo et al 2017), not as "How much water do we need?"…”

Process-based model of fish incubation survival for designing reservoir operations: a case study for Sacramento River winter-run Chinook salmon

Allocating reservoir flows to meet societal and ecosystem needs under increasing demands for water and increasing climatic variability presents challenges to resource managers. Often, regulated rivers have been operated to meet flow and temperature compliance points that mimic historical patterns. Because it is difficult to assess if this approach is efficient or equitable, new more process-based approaches to regulation are being advanced. This paper describes such an approach with a model of egg incubation survival of Sacramento River winter-run Chinook salmon (SRWRC, Oncorhynchus tshawytscha). Thermal mortality only occurs in a critical window around egg hatching when the embryo is most sensitive to temperature stress. The duration of the critical window has significant implications for Shasta Reservoir operations that are designed to control temperature during SRWRC incubation. Previous operations sought to maintain a low temperature over the entire incubation period. However, model analysis suggests that targeting cold water directly to the critical egg hatching stage provides higher survival while requiring less cold water resources. The calibrated model is publicly accessible through a web interface connected to real-time river and fish databases and a river temperature forecast model. The system is an example of the next step of river management that integrates databases with hydrological and process-based biological models for real-time analysis and for forecasting effects of river operations on the environment.

Twenty‐five essential research questions to inform the protection and restoration of freshwater biodiversity

Freshwater biodiversity is declining at an unprecedented rate. Freshwater conservationists and environmental managers have enough evidence to demonstrate that action must not be delayed but have insufficient evidence to identify those actions that will be most effective in reversing the current trend. Here, the focus is on identifying essential research topics that, if addressed, will contribute directly to restoring freshwater biodiversity through supporting ‘bending the curve’ actions (i.e. those actions leading to the recovery of freshwater biodiversity, not simply deceleration of the current downward trend). The global freshwater research and management community was asked to identify unanswered research questions that could address knowledge gaps and barriers associated with ‘bending the curve’ actions. The resulting list was refined into six themes and 25 questions. Although context‐dependent and potentially limited in global reach, six overarching themes were identified: (i) learning from successes and failures; (ii) improving current practices; (iii) balancing resource needs; (iv) rethinking built environments; (v) reforming policy and investments; and (vi) enabling transformative change. Bold, efficient, science‐based actions are necessary to reverse biodiversity loss. We believe that conservation actions will be most effective when supported by sound evidence, and that research and action must complement one another. These questions are intended to guide global freshwater researchers and conservation practitioners, identify key projects and signal research needs to funders and governments. Our questions can act as springboards for multidisciplinary and multisectoral collaborations that will improve the management and restoration of freshwater biodiversity.
