Abstract [en]

The chemical stabilization, or immobilization, of trace elements (metals and metalloids; TE) in contaminated soil has been studied for decades. A vast number of scientific publications are available on the method performance in laboratory settings, reporting that the application of various soil amendments to contaminated soil reduces TE mobility, bioavailability and toxicity. The most commonly used soil amendments include organic matter, iron oxides, phosphates, ashes, and lately biochar, alone or in combination with each other and/or lime. Most of the implemented field studies show a certain degree of improvement in soil and/or vegetation status following amendment. Regardless the positive performance of the technique in the laboratory, field validations and demonstrations remain scarce. The establishment of a field experiment often involves permits from authorities and agreements with site owners, both of which are considerably more time-consuming than laboratory tests. Due to conservative institutional structures, public authorities have been slow to adopt alternative remediation technologies, especially when the total TE concentration in soil remains the same and all of the associated risks are not yet convincingly described. For this reason, researchers should also focus on enhancing public knowledge of alternative remediation techniques so that future projects which aim to demonstrate the effectiveness of in situ immobilization techniques under natural conditions will be supported.

Abstract [en]

This paper performs a quantitative analysis of iron ore prices, and is an extension of Wårell (2014), which analyzed the change in iron ore pricing regime on iron ore prices using data from 2003 until September 2012. However, considering that the iron ore market still was characterized by surging prices in 2012, it is of interest to see if the same conclusions hold today when the latest commodity boom has come to an end. The quantitative analysis uses monthly data between January 2003 and June 2017, and performs both statistical tests for structural breaks and a reduced price regression of the most important factors for iron ore prices during the time period. The overall results indicate that the change in pricing regime does not have a significant impact on the iron ore prices when extending the time period; rather, it is the end of the commodity boom in 2014 that is picked up as a structural break in the price series. Furthermore, results regarding whether the variables are cointegrated are more inconclusive when analyzing the entire commodity boom. However, the result that GDP growth in China has had the strongest impact on iron ore prices is though robust when extending the time period. To conclude, even though the commodity boom now has come to an end the developments in China still seems to be the most influential factor determining international iron ore prices.

Abstract [en]

The way in which mining contributes to job opportunities in the region where it takes place has become increasingly important for the industry’s relations to the local community. The employment impacts of mining are however far from straightforward to assess. Considering these uncertainties about real-life job impacts, it is vital that there are sound assessments of these employment effects. The purpose of this paper is to apply a novel econometric approach to assess mining-induced job multipliers in the empirical context of northern Sweden. This analysis employs data on the number of employees in selected non-mining sectors and in the mining sector, respectively, and covering the relatively recent mining boom period (2003-2013). We also highlight differences across the two main mining counties in northern Sweden. The results show a positive statistical relationship between increases in the number of employees in the mining sector and changes in the number of employees in other sectors. The private services sector is particularly affected, while the industrial sector also benefits in the specific case of mining municipalities. The results also indicate relatively large inter-county differences, in turn highlighting the importance of addressing the context-specific circumstances when estimating the employment effects of mining.

Abstract [en]

Land use should meet current and future societal needs while keeping conflicts bounded and functional (e.g. at a minimum). Analysis of mapped data has become an important part of understanding and managing land use. This paper discusses the economic characteristics of geological information in relation to land use conflicts and the impact of adopting different pricing models for the provision of geological information. Moreover, we highlight some aspects that may make geological maps less pertinent than other geoinformation sources, given the often scarce data, slow diffusion and the high cost of investing in additional information.

Abstract [en]

The exploitation of minerals in Europe is a necessary activity for securing continued growth and development of the European society. In order to ensure this, it is vital that access to mineral deposits is safeguarded, which is why there is currently an increased focus on “defining mineral deposits of public importance” in Europe. However, there are a number of countries that have already defined mineral deposits of public interest on a national level, for example Sweden. The main purpose of this paper is to analyse the definition of mineral deposits of national interest in Sweden. The paper further aims at discussing the value of geological information in this process.

Abstract [en]

The purpose of this paper is to analyze long-run electricity demand behavior in the Swedish mining industry with special emphasis on the impact of energy prices and private research and development (R & D) on electricity use. Methodologically, we estimate a generalized Leontief variable cost function using a panel data set of nine mining operations over the time period 1990-2005. Since the lower boundary of a set of short-run cost functions confines the long-run cost function, we can compute the long-run own- and cross-price elasticities of electricity demand. The empirical results indicate that long-run electricity demand in the mining industry is sensitive to changes in the own price, and already in a baseline setting Swedish mining companies tend to allocate significant efforts towards improving energy efficiency, in part through private R & D. From a policy perspective, the results imply that taxes (and tax exemptions) on electricity can have significant long-run impacts on electricity use. Moreover, future evaluations of so-called voluntary energy efficiency programs must increasingly recognize the already existing incentives to reduce energy use in energy-intensive industries
