“…Arthropod abundance was highest in wastewater irrigated fields and lowest under rainfed and well water conditions. A possible explanation for this may be the higher quantity and quality of the foliage, stimulated by nutrient-rich wastewater, thereby attracting herbivorous insects, as observed in Ouagadougou, Burkina Faso by Stenchly et al [ 13 ], who recorded high abundances of orthopterans and hymenopterans in spinach fields ( Spinacia oleracea L.) irrigated with wastewater. Another explanation could be the well-developed olfactory system of insects [ 50 ], which allows the rapid detection of carbohydrates in irrigation wastewater [ 51 ].…”

“…In addition, the shift in agricultural land use from wind-pollinated crops, such as sorghum ( Sorghum bicolor Moench ), millet ( Pennisetum glaucum (L.) R.Br . ), and maize ( Zea mays L.), to crops that rely on insect pollination for seed and fruit development, such as okra ( Abelmoschus esculentus (L.) M oench) , pepper ( Capsicum annum L.), and garden eggs ( Solanum aethiopicum L.) [ 13 ], has led to increased dependence of West African farmers’ livelihoods and food security on the existing biodiversity [ 14 ]. Cities are hotspots of biological invasions.…”

Urban and peri-urban agricultural (UPA) production systems in West African countries do not only mitigate food and financial insecurity, they may also foster biodiversity of arthropods and partly compensate for structural losses of natural environments. However, management practices in UPA systems like irrigation may also contribute to disturbances in arthropod ecology. To fill knowledge gaps in the relationships between UPA management and arthropod populations, we compared arthropods species across different irrigation sources in Tamale. During a 72-h sampling period, 14,226 arthropods were caught with pitfall traps and pan traps from 36 fields. These specimens comprised 13 orders, 103 families, 264 genera, and 329 taxa (243 identified species, 86 unidentified species) and categorized into five feeding guilds (carnivores, decomposers, herbivores, omnivores, and pollinators). Species richness, species accumulation curves, and diversity functions (richness, evenness, and dispersion) were calculated to characterize the arthropod community. Non-metric multidimensional scaling was applied to examine structural similarity of arthropod communities among sites. To account for the effects of soil-related data, we furthermore applied a redundancy analysis. Arthropods grouped according to the irrigation water source, whereby the dipterans were most dominant under wastewater conditions. Here, particularly the eye gnat, Hippelates pusio, a disease-causing vector for humans, accounted for the dipterans. The occurrence of three alien ant species suggested community shifts through invasive species, while the occurrence of seven ant species (at least one ant species occurred under each water source) that form mutualistic relationships with aphids highlighted future risks of aphid pest outbreak. Future studies on these taxa should specifically target their ecological and economic effects and potential countermeasures.

“…If wastewater treatment is performed correctly, it can turn waste into a useful resource. If not, it could potentially lead to environmental pollution, and even endanger human civilization (Gilcreas, 1966;Arshad et al, 2017;Stenchly, Dao, Lompo, & Buerkert, 2017). Therefore, the selection of an appropriate wastewater treatment plan is a critical part of the scientific treatment of wastewater.…”

As the need for environmental protection and resource sustainability has increased in recent times, wastewater treatment has become increasingly important. In this paper, a group decision-making model for plans selection in wastewater treatment is proposed. In order to deal with uncertainties and multiple attributes in wastewater treatment, an intuitionistic fuzzy set is employed to evaluate wastewater treatment plans effectively. A distance measure is defined to obtain an objective weight measuring the expert’s judgment. More specifically, experts first use group decision-making on the various plans with an intuitionistic fuzzy set. Meanwhile, Due to the decision-makers psychological behavior, the prospect theory is applied. Next, the various plans are ranked by The Order of Preference by Similarity to Ideal Solution (TOPSIS) method and prospect theory. Finally, an illustrative example of wastewater treatment plans selection is used to verify the proposed model.

“…Therefore, the volume that is generated during the production of biogas is not totally reusable in another process. In addition, the inadequate application on soil can cause potential risks to human health and the environment, as it also contains heavy metals, potential pathogens and recalcitrant organic pollutants (Stenchly, et al, 2017;Nkoa, 2014). Some techniques are employed in order to avoid these problems.…”

The oil/gas, ethanol, biodiesel and biogas industries generate wastewater known as produced water, vinasse, crude glycerin and methanogenic digester´s based effluents, respectively. Microalgal systems have been suggested as a suitable and adaptable biological approach for the treatment of such wastewaters. The advantage of such an approach is the combination of treatment with the accumulation of algal valuable bioproducts. This systematic literature review aims to analyze scientific and patent production with bibliometric analysis. Another aim is to discuss the algal bioremediation strategies that were adopted by the cited industries for treating their distinct effluents. Data was obtained using scientific papers and patents published between 2000 to 2020 (335 scientific papers and 104 patents). The United States contributed with the largest number of articles, followed by China and Brazil. Meanwhile China, South Korea and the United States are the major owners of patents. This work identified that microalgal based system is successful in bioremediating several pollutants and that glycerol significantly improves algal performance for bioproducts production. Nonetheless, the efficiency of this process is hindered either by the adopted strategy applied before the cultivation stage or after this process. For instance, variables such as nutrient supplementation, turbidity and salinity corrections were identified as pivotal for process performance. Thus, the full-scale process is directly associated to the correct integration of wastewater production and proper management of microalgae systems.
