“…The best performance is to approach the best state of water environment governance. The TOPSIS model is an "approximate ideal solution ranking" method, which is mainly used in system engineering to solve the problem of multiobjective decision-making with finite schemes [29,30]. Compared with other methods, the TOPSIS method has no strict requirements for the indicator data, sample content, and data distribution, but can make full use of the original data in the evaluation index with less loss of information.…”

The performance of the regional water environment integrated governance is affected by many factors. This study took place in Henan Province, China, as the research area, and constructed an index system through the comprehensive consideration of three target layers based on the Ecological-Social-Economic (ESE) framework. Due to advantages such as strong objectivity and operability, the improved entropy-weight technique for the order of preference by similarity to the ideal solution (TOPSIS) model can greatly overcome subjective human interference and render the evaluation results more reliable. Therefore, it was introduced to evaluate the water environment integrated governance in Henan from 2007 to 2016. By applying the obstacle degree model, the obstacle factors were then diagnosed. The results of this study show that the overall performance of the integrated governance was generally improved in Henan from 2007 to 2016. Performance levels of the three target layers exhibited different trends, of which the social and economic benefits presented a linear increase year by year, but the ecological benefits presented a fluctuating downward trend. The obstacle on the Henan water environment integrated governance mainly comes from the ecological and economic benefits index. Therefore, a series of countermeasures have been proposed as a means of improving the governance performance in Henan.the new era. To promote the construction of ecological civilization, the governance of environmental pollution must be accelerated as soon as possible. In this study, research into the issue of water environment integrated governance has gradually become a focal point. The formulation of a scientific and reasonable mechanism to evaluate the performance of water environment integrated governance is currently a significant issue in both the theory and practice of water environment improvement.The shortage and serious pollution of water resources are severe obstacles to meeting the demand for clean water [5,6]. Academic research on the water environment governance from different perspectives has been emerging in an endless stream [7]. At present, the research mainly includes the vulnerability of water resources [8], evaluation of water quality [9], and methods of urban water governance [10]. The construction of evaluation indexes has gradually changed from the traditional viewpoint of 'water ecological' to the more comprehensive evaluation of ecology, society and economics [11,12]. For example, Fekete and Stakhiv studied the establishment of such indicators for a performance evaluation index system, and outlined a conceptual framework for indicators suitable to guiding both the water management planning as well as implementation evaluation [13]. On the basis of the ILBM (Lake Basin Management Initiative), Chidammodzi and Muhandiki built an indicator system from two aspects, namely the water resource subsystems and socioeconomic subsystems for the evaluation of water environment governance in the Lake Malawi Basin [14].The existing rese...

“…As explained before, the Multi-Attribute Theory (MAUT) method was selected to interpret the identified attributes and the Analytical Hierarchy Process (AHP) was used to assign weights to the selected attributes. This approach has been used in similar studies in the field [15][16][17]22,57], and is considered useful and adaptable [46]. Table 1 summarizes the attributes and indicators (with codes) identified to assess the sustainability of RWSS with their corresponding weights and data collection methods.…”

“…The tool can also be used in contexts similar to that of the case study (e.g., community-managed, gravity-fed systems with household connections). In general, available tools (such as the one developed in this paper) can be used to assess individual systems [5,15], with some focusing on systems accessing a specific type of water source, such as groundwater [16].…”

“…There are a number of studies that have developed multidimensional assessments of rural water supply systems in developing countries using multi-criteria analysis, specifically the Analytical Hierarchy Process (AHP). In some of these studies, AHP is used to select suitable alternatives for water provision [11,12], whereas others focus on the assessment of water supply services at a country level [13], district level [14], the individual family level [5,15], or the collective water system level [16,17]. Molinos-Senante et al [17] assessed and compared 40 rural water supply systems in Chile.…”

Rural water supply systems (RWSS) in developing countries typically have deficiencies that threaten their sustainability. This research used Multi-Criteria Analysis and the Analytical Hierarchy Process to identify indicators that can be used to assess the sustainability of RWSS. The assessment tool developed is composed of 17 attributes with 95 quantifiable indicators. The tool enables the assessment of the sustainability of RWSS, using data collected through semi-structured interviews, social cartography, technical inspection, household surveys, and water monitoring. The tool was applied in a case study of a RWSS in the Andean region of Colombia, illustrating a participatory, holistic, and structured assessment that provided a single sustainability measure for the system (3.0/5.0). The tool’s completeness is represented by its extensive attributes and indicators that deliver a robust baseline on the state of a system, help identify improvement strategies, and monitor system performance over time that can assists rural community organizations with RWSS management.

“…The use of Moringa olefeira (MO) seed extract has been identified as a water treatment technology suitable to the landscape of a developing country [10]. It has been demonstrated in literature that MO seeds contain active agents which have the capacity to sequestrate a variety of pollutants in water [11][12].Suarez et al [13] have shown that the MO seed has the ability to inactive bacteria and flocculate other organic matter in water.…”

The absence of comprehensive programs in regulating release of lead to the environment in growing cities situated in developing countries results to widespread intrusion of lead bioaccumulation in their primary sources of food. As a result, a significant increase in lead related diseases continually grows in many low income regions. In an attempt to provide a means of minimizing lead bioaccumulation, we test the extent to which Moringaoleifera seeds (MOS) removes lead (II) ions in aqueous solution. A box-behnken experimental design was used to obtain the optimal conditions in the lead (II) removal process. MOS dosage, initial lead (II) concentration, and pH were found to have significant effects on the percent removal of lead (II) in solution. Actual values of these independent variables were chosen on the basis of preliminary experimental results. Optimum conditions were found to be: MOS dosage 10.0 g/L, initial lead (II) concentration 20.0 ppm, and pH at 5.5. Lead removal using MOS was also performed at optimal conditions. In conclusion, a high lead (II) removal using MOS strongly suggests its potential to be used as a means of treating liquids highly contaminated with lead.
