Applying value of information methods to prioritize elements for water quality management with an example of linear alkylbenzene sulfonate in the Yodo River, Japan

Technical assessment and decision making for the environmental recovery of waterways and their banks: a science-based protocol

“…On the other hand, water resources globally are degraded by a multifaceted combination of stressors, resulting from a variety of drivers (Beechie et al 2010). Problems of degradation in rivers and their adjacencies can be physical, chemical and/or biological, and the degradation process is usually linked to soil erosion, pollution, missing of riparian vegetation and excessive fishing (Le et al 2014). These can occur at different intensities, because of both the nature of the degrading activity and the local environmental factors.…”

“…Establishing criteria to recover the ecological properties of water resources would be helpful to decision makers, especially in cases where little data and financial budgets limit the development of appropriate management plans, and consequently, result in the degradation of many rivers (Le et al 2014).…”

The expected value of perfect information in unrepeatable decision-making

“…Many applications have been made in different branches of science and technology, including agriculture (Meza et al, 2003); medicine (Felli and Hazen, 1998;Welton et al, 2011;Briggs et al, 2012) ; pharmacy (McCullagh et al, 2016); and engineering (Chazarra et al, 2017;Le et al, 2014). This last article forms part of an interesting monograph about the value of information that includes numerous other references (Keisler, 2014).…”

Modelo de avaliação da qualidade da água utilizando geoquímica e bioindicadores

“…Le et al (2014) ressaltam que a eficiência para a tomada de decisão quanto à gestão da qualidade da água é fundamental para redução de custos financeiros e ambientais. Os autores propõem em seu estudo um modelo de qualidade de água aglomerado, com sensibilidade e análise de incerteza, e um domínio de gerenciamento, incluindo a estimativa de perda e valor da análise da informação e consequentemente, indo além dos valores máximos e mínimos determinados pelos órgãos ambientais para os parâmetros de qualidade da água.…”

“…According to Rodriguez et al (2014) in the last few years, the political and technical factors with the quality modelling water, monitoring of nutrients and sediments, pesticides and pollutants in the ponds and rivers influenced in the environmental policy changes. Le et al (2014) emphasizes that the efficiency of the decision-making regarding water quality management is fundamental to reduce financial and environmental costs. The authors suggest in their study a quality model of water pattern with the sensibility and unsureness analysis and with a management domination including the loss estimative and the data value analysis.…”
