Abstract. This study aimed to develop a risk-based approach for determining control areas to manage non-point source pollution, developing a framework to prioritize catchments by considering the characteristics of polluted runoff from non-point sources. The best management, decision-making, and scientific approaches, such as the technique for order of preference by similarity to ideal solution (TOPSIS) and the Delphi technique, are required for the designation of control areas and the application of the best management practices to the control areas. Multi-criteria decision-making (MCDM) methods can handle the diversity and complexity of non-point source pollution. The Delphi technique was employed for selecting the assessment criteria/sub-criteria and determining their weights. Sub-criteria for each catchment unit were scored with either a quantitative or qualitative scale. All non-point pollution sources in mainland Republic of Korea were included, with the exception of a few islands, with catchment prioritization and pollution vulnerability evaluations shown as thematic maps. This study contributes to the field by developing a new risk-based approach for ranking and prioritizing catchments; this provides valuable information for the Ministry of Environment to use to identify control areas and manage non-point source pollution.

“…3.0) decision support software, was employed (Janssen and van Herwijnen 1994). With this software it was possible to evaluate the performance of criteria/sub-criteria using a range of analytical methods, while it was also possible to carry out uncertainty and sensitivity analyses related to variations in the criteria/sub-criteria weightings (Chon et al 2012). In this study we used the elementary MCA analysis based on the weighted summation method.…”

Preventing food wastage is a key element of sustainable resource management. But as food waste is still generated at high volumes, priority is placed on its proper management as a resource, maximising sustainability benefits. This study, by integrating a multi-criteria decision analysis with a sustainability assessment approach, develops a screening and decision support framework for comparing the sustainability performance of food waste management options. A structured process for selecting criteria based on the consideration of environmental, economic and social aspects related to region-specific food waste system planning, policy and management has been developed. Two food waste management options, namely the use of food waste disposal units, which grind food waste at the household's kitchen sink and discharge it to the sewer, and the anaerobic co-digestion of separately collected food waste with sewage sludge, were selected for comparison due to their potential to create synergies between local authorities, waste and water companies, with local circumstances determining which of the two options to adopt. A simplified process used for assessing and comparing the two food waste management options in the Anglian region in the UK, indicated that there are benefits in using the framework as a screening tool for identifying which option may be the most sustainable. To support decision-making, a detailed analysis that incorporates stakeholders' perspectives is required. An additional use of the framework can be in providing recommendations for optimising food waste management options in a specific region, maximising their sustainability performance.

Water pollution by nitrogen originates at diffuse and point sources. In surface aquatic systems, nitrate is one of the most problematic forms of nitrogen, causing phytoplankton and macrophyte growth and consequently water eutrophication. This study evaluated whether the Soil and Water Assessment Tool (SWAT) model can simulate nitrate load in a rural watershed in daily and monthly time increments. The study investigated 462 km² of the upper part of the Stör catchment, a typical rural lowland catchment located in Northern Germany. The results showed that simulations of nitrate load at monthly increments are better predictors of observed data than daily simulations. The most effective practices to minimize the NO3-N load were the reduction of nitrogen fertilizer application and the increasing of conservation areas, such as field filter strips.Keywords: land use, nitrogen pollution, non-point pollution, SWAT model. Melhores práticas de manejo para reduzir a poluição por nitrato em uma bacia hidrográfica rural na Alemanha RESUMOA poluição da água causada por nitrogênio é originada por fontes difusas e pontuais. Em sistemas aquáticos superficiais, o nitrato é uma das formas mais problemáticas de nitrogênio, causando crescimento de fitoplâncton e de macrófitas e consequentemente a eutrofização da água. Este estudo teve o objetivo de avaliar se o modelo Soil and Water Assessment Tool (SWAT) pode simular a carga de nitrato em uma bacia hidrográfica rural em séries diárias e mensais. Foram investigados 462 km² da parte superior da bacia hidrográfica do rio Stör, uma bacia de planície tipicamente rural localizada no norte da Alemanha. Os resultados mostraram que as simulações de carga de nitratos em incrementos mensais são melhores preditores de dados observados do que simulações diárias. As práticas mais efetivas para minimizar as cargas de NO3-N foram a redução da aplicação de fertilizante nitrogenado e o incremento de áreas de conservação, tal como as faixas filtro.Palavras-chave: nitrogênio, polluição difusa, modelo SWAT, uso da terra. 889Best management practices to reduce nitrate pollution ...Rev.
