Paper compares Czech and German methodology for the disproportionate costs evaluation.

ABSTRACT: The EU Water Framework Directive requires all water bodies within EU member states to achieve the “good status” by 2015/2021/2027. As it has proved to be very challenging for many water bodies, demand for cost proportionality analysis has increased dramatically, because disproportionate costs are one of the justifiable reasons for a deadline extension. This has led to development of many approaches across Europe. Among others, the Czech official methodology based on monetary cost-benefit analysis and the German “New Leipzig approach” based on criteria and cost threshold were introduced in 2015. Both approaches estimate costs of achieving the “good status”, but differ significantly in evaluating benefits. The Czech methodology identifies various categories of benefits, monetizes them and later compares them with costs of measure implementation. The German methodology determines how proportionate it is to spend on measures based on past public expenditures, objective distance to the “good status” and generated benefits. Both methodologies were tested on a small Stanovice catchment in the Czech Republic with similar results, which allows for a comparison of the two approaches they represent. Achieving the “good status” is viewed as cost-proportionate. Application of both methodologies is associated with numerous problems (e.g., data availability, estimate accuracy), which are further discussed in the paper.

Are socio-demographic variables relevant factors of municipal waste generation?

ABSTRACT: Increasing pressure of the European Union on diverting municipal waste from landfills requires an active role of households and commands a radical change of their behavior. Knowledge of behavioral patterns enables an effective design of municipal waste management systems. Based on several factors influencing environmental behavior, this paper aims at analyzing differences in municipal waste generation among Czech municipalities using socio-demographic factors. A set of 12 characteristics for 5445 Czech municipalities was investigated. Using ordinary least squares regression, we developed a model with eight indicators describing household size, gender, completed education level and diverse housing characteristics. Even though the model explains only 5.1% of waste generation variability among Czech municipalities, it is statistically significant. Other factors such as age or population density do not improve the model significantly. The resulting model will be used as a basis for further spatial analysis.
