Due to the constant growth of human population and anthropological activity, it has become necessary use sustainable affordable technologies that satisfy current future demand for agricultural products. Since nutrients available plants in soil are limited need increase yields crops is desirable, chemical (inorganic or NPK) fertilizers been widespread over last decades, causing a nutrient shortage due their misuse exploitation, because uncontrolled these products, there latent environmental health problem globally. For this reason, green biotechnology based on microalgae biomass proposed as alternative development improvers crop cultivation phytoremediation. This review explores long-term risks using both (cancer hypoxia) environment (eutrophication erosion), well potential substitute fertilizer different treatments application methods implementation soil; additionally, can be source carbon mitigation wastewater treatment agro-industrial processes.

<p>Cyanobacterial blooms, occurring frequently in eutrophic freshwaters worldwide, are considered as potential hazards to ecosystems and human health, it is often difficult expensive control their outbreaks large lakes through reduction of nutrient loadings. Biomanipulation, launched an ecology-based solution the 1970s, was once believed be effective way counteract cyanobacterial blooms. It divided into traditional biomanipulation (TB) nontraditional (NTB) that use filter-feeding <i>Daphnia</i> fish, respectively. There have been numerous reviews on former, yet few latter. Here, we first revisit debate digestibility cyanobacteria silver bighead carp. Then, review 42 experiments clearly mention changes reveal substantial reductions abundance by carp 88% cases. In particular, a whole-lake experiment Lake Donghu, increased stock effectively decreased <i>Microcystis</i> blooms from coverage 87% 2021 0% 2022. Finally, discuss possible factors related NTB��s effectiveness depends not only standing stock, niche divergence shape preference fish but also trophic status waterbodies. Particularly, feed more colony-forming than filamentous cyanobacteria, capable increasing small-sized algae. NTB can used prevent or diminish poorly grazed <i>Daphnia</i>, providing sustainable in-lake ecotechnology combat heavy waterbodies.</p>

Sustainable lake restoration: From challenges to solutions

Wiley Interdisciplinary Reviews Water, Год журнала: 2023, Номер 11(2)

Опубликована: Авг. 31, 2023

Abstract Sustainable management of lakes requires us to overcome ecological, economic, and social challenges. These challenges can be addressed by focusing on achieving ecological improvement within a multifaceted, co‐beneficial context. In‐lake restoration measures may promote more rapid ecosystem responses than is feasible with catchment alone, even if multiple interventions are needed. In particular, we identify methods that support the overarching societal target circular economy through use nutrients, sediments, or biomass removed from lake, in agriculture, as food, for biogas production. this emerging field sustainable techniques, show examples, discuss benefits pitfalls, flag areas further research development. Each lake should assessed individually ensure approaches will effectively address lake‐specific problems, do not harm downstream ecosystems, cost‐effective, delivery valuable services, minimize conflicts public interests, eliminate necessity repeated interventions. Achieving optimal, results relies multidisciplinary close interactions between environmental, social, political, economic sectors.

Explore before you restore: Incorporating complex systems thinking in ecosystem restoration

Journal of Applied Ecology, Год журнала: 2024, Номер 61(5), С. 922 - 939

Abstract The global movement for ecosystem restoration has gained momentum in response to the Bonn Challenge (2010) and UN Decade on Ecosystem Restoration (UNDER, 2021–2030). While several science‐based guidelines exist aid achieving successful outcomes, significant variation remains outcomes of projects. Some this disparity can be attributed unexpected responses components planned interventions. Given complex nature ecosystems, we propose that concepts from Complex Systems Science (CSS) are linked non‐linearity, such as regime shifts, ecological resilience feedbacks, should employed help explain an perspective. Our framework, Explore Before You Restore, illustrates how these impact by influencing degradation recovery trajectories. Additionally, incorporating CSS into typical project cycle through a assessment phase suggest need is explicitly included improve outcomes. To facilitate inclusion make it workable practitioners, describe indicators methods available teams answer key questions up assessment. In doing so, identify outstanding science policy tasks needed further operationalize restoration. Synthesis applications . By illustrating non‐linear threshold behaviour trajectories, our framework Restore demonstrates incorporate thinking We argue cycles, more broadly, international guidelines, may significantly

Practices for Eutrophic Shallow Lake Water Remediation and Restoration: A Critical Literature Review

Lake water has been impaired with nutrients due to the synergic action of human-made activities and climate change. This situation is increasing eutrophication around globe faster than before, causing degradation, loss its uses, water-associated economic health effects. Following Sustainable Development Goal 6, more precisely target 6.6, nations are already behind schedule in protecting restoring water-related ecosystems (i.e., rivers lakes). As concerns escalating, eutrophic remediation practices keys for those lake waters. Diverse methodologies have investigated focusing on nutrient that limit primary productivity phosphorus), but few applied in-lake remediation. Thus, objective this paper provide an overview critical comments approaches facing Information successful cases possible challenges/difficulties peer-reviewed literature presented. should be useful supporting further project selection by stakeholders involved.

Can reductions in water residence time be used to disrupt seasonal stratification and control internal loading in a eutrophic monomictic lake?

Journal of Environmental Management, Год журнала: 2021, Номер 304, С. 114169 - 114169

Anthropogenic eutrophication caused by excess loading of nutrients, especially phosphorus (P), from catchments is a major cause lake water quality degradation. The release P bed sediments to the column, termed internal loading, can exceed catchment load in eutrophic lakes, those that stratify during warm summer periods. Managing challenging, and although range approaches have been implemented, long-term success often limited, requiring lake-specific solutions. Here, we assess manipulation residence time inhibit Elterwater, shallow stratifying English Lake District, UK. Since 2016, additional inflowing has diverted into inner basin Elterwater reduce its time, with intention limiting length stratified period reducing loading. Combining eight years field data Before-After-Control-Impact study process-based hydrodynamic modelling enabled quantification intervention effects on stratification length, column stability, concentrations chlorophyll P. Annual was reduced around 40% (4.9 days). Despite this change, continued developed hypolimnetic anoxia. As result, there little significant change (as total or soluble reactive phosphorus) concentrations. Summer 2 days shorter 7% less stable intervention. Our results suggest insufficient induce large enough physical changes improve quality. However, minor management measure had some impact larger may potential reductions Future assessments requirements should combine multi-year observations provide improved understanding effect size required alter structure lake, leading increased oxygen for
