“…Key environmental indicators can be incorporated into the assessment and the methods can be applied to data from any region. The results can be used to rank production alternatives according to their relative effectiveness (Sattler et al 2010;Lv 2007). This is the first time these approaches have been used to assess multiple EAPs in China.…”

“…Nitrate leakage risk assessment using fuzzy logic Fuzzy logic provides highly flexible frameworks enabling integration of various types of information (including words, and thus qualitative human thought processes) in the analysis of complex systems and decisions (Sattler et al 2010). It has already been used to evaluate fertilizers' environmental impact, and specifically nitrate leakage (Sattler et al 2010;Uthes et al 2011), using a MATLAB and Fuzzy Logic Toolbox Release XXX model (The MathWorks, Inc., Natick, MA, USA).…”

“…It has already been used to evaluate fertilizers' environmental impact, and specifically nitrate leakage (Sattler et al 2010;Uthes et al 2011), using a MATLAB and Fuzzy Logic Toolbox Release XXX model (The MathWorks, Inc., Natick, MA, USA). Briefly, input data are translated by the fuzzy-logic model into a consistent language, processed according to rules and fuzzy membership functions, then the results from the rule-based assessment are translated into output values through a final defuzzification step ( Fig.…”

“…Effects of these two parameters on nitrate leakage under the five local EAPs (Table 2) were assessed. ( 2 ) A s s i g n m e n t o f m e m b e r s h i p f u n c t i o n s (fuzzification) Due to the uncertainties surrounding nitrate leakage from agricultural land and the complexity of factors involved, the impact of land use-related factors on nitrate leakage can often only be expressed as generalizations, rather than using specific values (Sattler et al 2010). Thus, interrelations can only described by approximate rules, e.g., if the amount of applied nitrogen is 'large', then the risk of nitrate leakage is 'high', rather than quantitatively, e.g., if the amount of applied nitrogen is 200 kg/ha, then 50% of the applied amount of N will be leached to groundwater.…”

“…1 The main components of the fuzzy-logic system lower the nitrate leakage risk. Thus, the promotion of EAPs should focus on those assigned high index values (Sattler et al 2010). As an example, the calculation of nitrate leakage risk for the M1 (Minimum and no tillage) practice is presented in Fig.…”

Agricultural nonpoint source pollution in China has been the major environmental problem, so environmental-friendly agricultural practices (EAPs) must be promoted to improve environmental quality. However, the most suitable practices for each agricultural region must first be identified. Thus, in the presented study a fuzzy-logic method and a revised empirical formula were used to assess nitrate leakage and N 2 O emissions, respectively, and to compare five EAPs in Xinxiang, a major grain-producing county in Henan Province, China. The required information was collected in face-to-face interviews with 10 extension service experts from the county, using a questionnaire to explore their opinions of the EAPs currently adopted by smallholder farmers, as well as the amounts, frequencies, varieties and proportions of nitrogen fertilizers applied annually. The results indicate that reduced tillage, soil testing and fertilizer recommendations would be the most appropriate practices to initially promote on a large scale in Xinxiang.

Agri-environmental measures are payments to farmers to reduce environmental risks or to preserve cultivated landscapes. These measures are codified in European Union regulations. Poor spatial targeting is one of the major causes of low cost-effectiveness in agri-environmental measures. Existing studies on spatial targeting focus primarily on selected individual measures; hence, they do not allow for conclusions at the program level, where the planning and implementing of decisions on a number of different measures has to be made. In this study, we analyzed the impacts of two spatial targeting options (targeting of erosion-reducing measures on erosion vulnerable areas; targeting of grassland extensification on N-pollution vulnerable areas) on the cost-effectiveness of the single measures and the entire agri-environmental program of the federal state of Brandenburg in Germany. The methodological steps included an analysis of empirical data on land use and program participation, an expert-based environmental impact assessment and a spatial allocation procedure based on linear programming. The environmental impact assessment delivered goal-specific index values for each measures-land parcel combination expressing the suitability of the measures for contributing to four regionally relevant program objectives. The cost-effectiveness of the measures and the program were calculated by putting budgetary costs in relation to the achieved environmental index sum. The calculated cost-effectiveness of the program in 2006 was 89.6% of the simulated optimal cost-effectiveness. The spatial targeting of erosion-reducing measures on erosion vulnerable areas caused an increase in the cost-effectiveness at the measures level and almost no changes at the program level. The spatial targeting of grassland extensification on N-pollution vulnerable areas, despite also improving the cost-effectiveness of this measure, had negative effects on the cost-effectiveness of the program.
