“…The National Research Council Committee on Best Practices for Risk‐Informed Remedy Selection, Closure and Post‐Closure of Contaminated Sites states “the decision‐making process requires the balancing of risk against benefit” (2014). In these publications, risk acceptability is operationalized in several ways, including (1) an explicit recognition that zero risk is not the goal (Delage et al., 2019 ); (2) a need to make tradeoffs with factors besides risk, such as cost (Latinopoulos, Mylopoulos, & Mylopoulos, 1997 ; Li, Huang, & Xue, 2014 ; Manap & Voulvoulis, 2014 ); and (3) discussion of the risk appetite or risk tolerance of the decisionmakers (Leach Bennett et al., 2011 ; Lipton & Gillett, 1992 ; Mirabi, Mianabadi, Zarghami, Sharifi, & Mostert, 2014 ; Opitz‐Stapleton et al., 2019 ). This theme is the one that is most aligned with the decision analysis modeling tool, multicriteria decision analysis.…”

Risk‐based Decision Making Definition: A Scoping Review of Food, Agricultural, Environmental, and Medical Literature

Risk‐based decision making (RBDM) is a term that is used frequently as an aspirational goal in many fields, including health, engineering, environmental science, regulatory and, more recently, food safety. When RBDM is used in the literature, many different types of criteria are used to characterize a decision process as being “risk‐based.” Like the parable about the blind men and the elephant, everyone is confident they know what RBDM means even though there is no universal definition. The use of RBDM is gaining wide acceptance and implies a level of rigor and focus that many decisionmakers and stakeholders are interested in adopting. However, without one clear definition, there are questions about what a RBDM approach really means. This study summarizes peer‐reviewed and gray literature that uses the term “RBDM” from the last 50 years in the agricultural, environmental, and medical areas. The criteria discussed were identified and organized into themes. A foundational definition is proposed to represent the most fundamental use of RBDM in the literature, and three themes covering the additional concepts presented in some of the literature were identified and added as themes within the definition. Results from this research will inform practitioners interested in following the principles of RBDM, and will help guide researchers who are interested in advancing this approach. The most immediate use will be to guide the development of a roadmap for a risk‐based food safety system for low‐ and middle‐income countries and to aid the global food safety community in moving toward RBDM.

Before joining the European Union, Serbia faces a big task related to the treatment and purification of wastewater. The capital of Serbia, Belgrade, and some larger cities do not have wastewater treatment plants. Although there are no plants in larger cities in Serbia, they still exist on the territory of the state itself. However, either they are not in good condition, or they do not work with the projected capacity or they do not work at all. This paper presents the model for risks quantification for the planning and design processes of wastewater treatment plants in which the risks are divided into 6 categories: legal, financial and economic, logistics, environmental protection, management and design risks. 37 risks have been defined, analyzed and evaluated by the experts participating in the Delphi method. Experts in various fields dealing with the planning, design or construction of wastewater treatment plants were selected to assess the risks through 2 rounds of Delphi methods and reach the consensus on major risks. By using statistical methods, it is determined that the experts reached the consensus after which each risk received its own relative weighting coefficient. Risk model has been initially verified by experts from Delphi team on two projects during construction phase. This model is important in the initial phases of the project, when the investor starts the project, as well as in the design phases.

“…Focusing on materials consumption and carbon emissions, Giannetti et al (2013) applied emergy-based indices to assess the sustainability of two alternative domestic wastewater treatment processes. Other studies had a different focus, as the discussion of uncertainties and trade-offs when implementing water and wastewater treatment projects (Mirabia et al, 2014), the use of material and energy resources for new projects (Vassallo et al;2009), and technical aspects behind the generation of electricity by sewage sludge digestion (Björklund et al, 2001).…”

Water resources are under pressure because of human activities. Its management faces the challenge of enhancing long-term water security while minimizing undesirable economic, social, and environmental impacts along with its production chain. Since water and wastewater treatment plants are designed to maintain and conserve freshwater provisioning services, it is paramount to understand how it operates before proposing options for sustainability. At this point, the diagnosis phase claims for methods scientifically-based, systemic, and more objective to provide information for decision-makers towards strategic management of water resources. This work applies the five-sector sustainability model (5SenSu) to assess Brazil's twenty major water and wastewater treatment companies (WWTC) to quantify their sustainability levels that allow ranking procedures and the establishment of benchmarks for improvements. Under comparative basis, results identified the top-three sustainable companies, CORSAN, CASAN, and SANEPAR, which should be considered examples of best practices. Specifically, the following best-ranked companies in each sector within 5SenSu should be used as benchmark patterns for more oriented best practices: SANEAGO, sector 1; AGESISA, sector 2; CORSAN, sector 3; CASAL, sector 4; MA, sector 5. This work contributes to the advancement in modeling sustainability assessment of human-managed systems (applied in WWTCs in this present study) from a systemic and epistemologically rooted approach, avoiding shortcomings and misleading discussions on the sustainability issue. Quantifying sustainability of WWTCS from 5SenSu allows the identification of those sectors/indicators that requires immediate cleaner production practices by decision-makers to improve overall sustainability, besides identifying those companies more aligned with the requirements of UN SDGs.
