The present paper attempts to identify the spatial patterns of soil nutrients at a waste disposal site in Haizhou opencast coal mine using geostatistical approach.108 soil samples were collected and analyzed for pH,organic matter(OM),NHN,available phosphorus(AP)and available potassium(Ak).The results indicate that nutrients exhibited different spatial distribution and only NHN exhibited strong spatial dependence and a relatively large nugget *** high content of OM,NHN,AP and Ak was seen in the northeastern part,whereas pH was higher in central north and southern parts of the waste disposal *** identification of the spatial variability and heterogeneity of soil properties and especially nutrients in waste disposal sites allows the assessment of soil quality and revegetation potential while it defines the possible need for amendments and the most feasible revegetation scheme.

The integration of sustainable development challenges and opportunities into the decision making process during the design and/or implementation of multi-disciplinary mining projects is generally not supported by decision support systems(DSS). A new hybrid decision support tool, which features an integrated assessment of sustainable development issues as they apply to mining projects, is hereby proposed. The proposed DSS framework, named ‘‘Acropolis DSS", can be used to assist involved stakeholders in critical decisions, especially when addressing issues such as stakeholder participation, transparency,and trade-offs. The proposed DSS is based on a multi-criteria decision analysis combined with the multi-attribute utility theory.

Assessment of agricultural production sustainability is a multi-dimensional task that involves the quantification of various economic,social and environmental indicators at different scales and uncertainty *** this context,a particularly challenging approach is proposed involving the appropriate selection of the most representative criteria that ensure economic viability,eco-friendliness and social development,in order to overcome the limitations of other methodological approaches that are often vague and *** this study,a holistic methodology that integrates life cycle analysis(LCA),environmental risk assessment(ERA)along with on-site farm and regional surveys using the multi-criteria environment of the Analytical Hierarchy Process(AHP)is designed for the identification of the most sustainable agricultural management practices at regional *** on a set of 13 representative sub-criteria,the proposed approach was applied to Pistacia vera *** in Aegina island,Greece,where narrow range of resources is available,groundwater supply is scarce and of poor ***,three alternative scenarios,*** scenario representing the current production(BL)as well as Composting(CO)and Biochar Use(BU)scenarios aiming at sustainability improvement were *** of multi-criteria and sensitivity analyses suggest that the optimal sustainable management scenario is CΟ,which involves on-site composting of organic solid waste,mainly produced at farm site,and subsequent application in the *** proposed methodology shows significant potential as a valuable multi-criteria tool that can be easily adapted at regional level to assist decision makers such as farmers and their associations,policy makers,local and regional authorities to efficiently explore a range of alternative farm management practices and thus identify pathways toward sustainability.
