Emerging global threats, such as biological invasions, climate change, land use intensification, and water depletion, endanger the sustainable future of lakes reservoirs. To deal with these a multidimensional view on protection exploitation reservoirs is needed. The holistic approach needs to contain not just development economy society but also take into account negative impacts this growth environment, from that, balance between three dimensions can be sustained reach future. As such, paper provides comprehensive review opportunities challenges for via critical analysis their contribution individual subsets Sustainable Development Goals (SDGs).

The Himalayas are dotted with a multitude of freshwater lakes varying sizes. These serve as the sole source water for multiple major human settlements in region and backbone to socio-economic services. Here, we provide comprehensive review available literature on hydro-ecology important Indian Northwestern (INWH). Numerous studies have been performed past but reported regional journals, scientific reports government research institutions local conference proceedings very few publications international journals.

Lake chlorophyll responses to drought are related to lake type, connectivity, and ecological context across the conterminous United States

Abstract Local and regional‐scaled studies point to the important role of lake type (natural lakes vs. reservoirs), surface water connectivity, ecological context (multi‐scaled natural settings human factors) in mediating responses disturbances like drought. However, we lack an understanding at macroscale that incorporates multiple scales (lake, watershed, region) a variety contexts. Therefore, used data from LAGOS‐US research platform applied local year timeframe 62,927 US reservoirs across 17 ecoregions examine how chlorophyll responds drought various We evaluated changes relative each lake's baseline year.

Anthropogenic forcing leads to an abrupt shift to phytoplankton dominance in a shallow eutrophic lake

Freshwater Biology, Journal Year: 2024, Volume and Issue: 69(3), P. 335 - 350

Published: Jan. 10, 2024

Abstract The timing and causes of lake eutrophication are often obscured when multiple anthropogenic disturbances coincide in space time. This issue is particularly problematic for shallow lakes arid regions that experience strong climatic forcing which alters hydrology water levels, further conflates causal drivers. We used Utah Lake (Utah, U.S.A.) as a model system to examine how natural hydrological variability influence ecosystem structure large climates. Paleolimnological analyses sedimentary biogeochemistry, pigments, DNA, morphological fossils were identify shifts primary production evaluate the relative regional climate‐driven humans on structure.

The Alqueva reservoir is essential for water supply in the Alentejo region (south of Portugal). Satellite data are to overcome temporal and spatial limitations situ measurements, ensuring continuous global quality monitoring. Data between 2017 2020, obtained from OLCI (Ocean Land Color Instrument) aboard Sentinel-3, were explored. Two different methods used assess reservoir: K-means group reflectance spectra into optical types (OWT), empirical algorithms estimate parameters. Spatial (in five areas reservoir) (monthly) variations OWT parameters analyzed, namely, Secchi depth, turbidity, chlorophyll a, phycocyanin concentrations. One cluster has been identified representing typical presence microalgae reservoir, mainly July October more intense northern reservoir.

Lake Cajititlán is a small, shallow, subtropical lake located in an endorheic basin western Mexico. It characterized by strong seasonality of climate with pronounced wet and dry seasons has been classified as hypereutrophic lake. This eutrophication was driven improperly treated sewage discharges from four municipal wastewater treatment plants (WWTPs) excessive agricultural activities, including the overuse fertilizers that reach through surface runoff during rainy season. nutrient rich caused algal blooms, which have led to anoxic or hypoxic conditions, resulting large-scale fish deaths occurred immediately after study investigated changes phytoplankton community season association between these physicochemical water quality environmental parameters measured lake’s basin. Planktothrix Cylindrospermopsis were dominant genera cyanobacterial community, while Chlorophyceae, Chrysophyceae, Trebouxiophyceae classes dominated microalgae community. However, results showed significant temporal shift communities induced The findings this suggest climatic variations cause high seasonal rapid (Chlorophyll- , DO, NH 4 + NO 3 – ) composition Finally, alternation phosphorus nitrogen limitation observed season, clearly correlating presence when limited nitrogen. evidence presented supports idea death could be mainly anoxia, Based on our review literature, first using throughput 16S rRNA 18S amplicon sequencing.

Improvements of the coupled WRF-Lake model over Lake Nam Co, Central Tibetan Plateau

Climate Dynamics, Journal Year: 2020, Volume and Issue: 55(9-10), P. 2703 - 2724

Published: Aug. 6, 2020

Abstract A series of model sensitivity simulations are carried out to calibrate and improve the Weather Research Forecasting Model coupled with a one-dimensional lake (WRF-Lake) based on observations over Lake Nam Co. Using default parameters, solution WRF-Lake exhibits significant biases in both thermodynamics regional climatology, i.e., higher surface temperature (LST), earlier onset summer thermal stratification, overestimated near-surface air precipitation induced by lake’s excessive warming moistening impacts. The performance is improved through adjusting initial profile, maximum water density (Tdmax), roughness length, light extinction coefficient. Results show that initializing spring observation mitigates LST overestimation reduces timing error stratification. By further Tdmax from 4 °C observed value 3.5 °C, increase June mid-July enhanced buildup stratification more accurately predicted. Through incorporating parameterized length decreasing coefficient, better reproduces daily evolution vertical profile. calibrated effectively over-lake at 2 m height regions downwind lake. This suggests an scheme within essential for realistically simulating lake–air interactions climate lake-rich Tibetan Plateau.
