Significant wetland loss in Ontario has resulted in the loss of important ecosystem services which help to mitigate the effects of global change. This research aimed to create a multi-criteria index for identifying where suitable sites for wetland reconstruction are spatially distributed in Ontario’s Mixedwood Plains. The index is intended as a decision-making tool for reaching wetland reconstruction goals such as those outlined by the Ontario MNRF’s plan to restore historically lost wetland area and function. By incorporating ecosystem services, the index will indicate areas where wetlands would be most beneficial. The resulting index generated a raster with a range of suitability based on seven criteria. Soil drainage and Agriculture were the most important criteria and weighed most heavily in the index. Overlay analysis indicated that suitable sites were clustered in areas which had historically undergone wetland loss or are areas of existing wetlands.

Purpose – This paper examines the nature and function of cost accounting at the Newcastle Infirmary, a large voluntary provincial hospital, established in 1751. In particular, the paper adds to the literature on accounting within early voluntary hospitals by identifying the relative contributions of the costing system to planning and controlling the operations, assisting decision making and holding managers accountable for their performance. Design/methodology/approach – The paper relies primarily on original documents preserved in the archives of the Newcastle Infirmary. Findings – Although evidence was found of quite sophisticated costing systems, the findings suggest that the majority of the information was produced ex post by the hospital management to demonstrate good stewardship and to engender financial support. Research limitations/implications – More cases are needed of other hospitals to ascertain how typical the Newcastle Infirmary was of the voluntary hospital sector in the nineteenth century. Originality/value – Although there are other studies of accounting within British voluntary hospitals, and studies of the use of accounting to drive decision making in profit-making organisations during the nineteenth century, none have investigated the use of accounting as a decision-making tool in a voluntary hospital.

The growing pressure on society due to global change requires better integration of ecosystem services (ES) into decision-making. Despite a growing number of ES assessments, Europe-wide information on recent changes of multiple ES is still rare. This study aimed at analysing changes in ES values between 2000 and 2018 across Europe based on land use/land cover (LULC) distribution. We mapped 19 ES for 52 ecoregions and identified six major groups of ecoregions with similar LULC distribution and trends. Our results indicated that provisioning ES mainly increased in the forest-dominated region (G2), decreasing in the near-natural grassland region (G1), the region with agricultural mixed systems (G3), and the intensively-used steppic region (G6). Regulating ES slightly decreased in G1 and G6, but increased in G2 and the wetland-dominated region (G5). Cultural ES had generally low negative trends for most ecoregions. In addition, our results revealed ecoregions with differing trends in ES that could be related to specific socioeconomic developments. Our findings provide spatial and quantitative information that can be used for policy development at European national and regional levels—as well as for monitoring of ES.

Abstract Coastal ecosystems are linked to socio-economic development, but simultaneously, are particularly vulnerable to anthropogenic climate change and sea level rise (SLR). Within this scope, detailed topographic data resources of Spercheios River and Maliakos Gulf coastal area in Greece, combined with information concerning the economic value of the most important sectors of the area (wetland services, land property, infrastructure, income) were employed, so as to examine the impacts of three SLR scenarios, compiled based on the most recent regional projections reviewed. Based on the results, in the case of 0.3 m, 0.6 m and 1.0 m SLR, the terrestrial zone to be lost was estimated to be 6.2 km2, 18.9 km2 and 31.1 km2, respectively. For each scenario examined, wetlands comprise 68%, 41% and 39% of the total area lost, respectively, reflecting their sensitivity to even small SLR. The total economic impact of SLR was estimated to be 75.4 × 106 €, 161.7 × 106 € and 510.7 × 106 € for each scenario, respectively (3.5%, 7.5% and 23.7% of the gross domestic product of the area), 19%, 17% and 8% of which can be attributed to wetland loss. The consequences of SLR to the ecosystem services provided are indisputable, while adaptation and mitigation planning is required.

Decision Making Tool

The choice of alternative techniques in urban stormwater drainage (infiltration and detention systems), in the course of a project, is most often made with a poor understanding of site constraints, and the possibilities afforded by these techniques. This gives rise to extra costs and also subsequent malfunctioning. To arrive at feasible choices, we have formalised the decision-making process, taking account of the multiple criteria and the large number of partners involved. At present, we are developing a decision-making tool for alternative techniques in urban stormwater management at the preliminary study stage. The first phase makes it possible to eliminate solutions which are unworkable (elimination phase). It is aimed at the designer. Work on the next phase (the decision-making phase), which is more complex, is in progress. It will make it possible, in collaboration with all the partners involved, to choose a stormwater drainage strategy which will best suit the objectives and the wishes of the partners. It uses multi-criteria methods.
