Résumé :
This paper explores how policy structure, institutions, and political climate impact the ability of the Surface Mining Control and Reclamation Act (SMCRA) to ensure the reclamation of surface coal mines. We conduct a policy review that traces the impacts of the three parts of SMCRA; Reclamation Standards, Reclamation Bonding Requirements, and the Abandoned Mine Land fund. We examine the implications the act and its approach have for the mining industry and their ability to reclaim mining areas. We find that each of the three parts of SMCRA’s approach face substantial problems in their implementation. Though largely a positive force for internalizing the environmental costs of surface mining, those issues commonly elucidated in the public choice literature reduce the efficacy of the policy approach and call into question the act’s ability to ensure reclamation occurs. Both in the structure of the bonding requirements and in the regulatory structure created by the act, misaligned incentives sometimes hamper effective reclamation. Further, the funds created under SMCRA to reclaim and restore mined lands have often been directed towards projects that are politically expedient for politicians instead of those that would best serve the fund’s original reclamation purpose. After revealing these problems and putting them in the context of the public choice literature, we suggest updates to the current policy that would align reclamation incentives and better ensure that the reclamation of surface mines occurs. We emphasize the cooperative elements of SMCRA and suggest how other countries, especially those without major existing frameworks for handling reclamation, can emulate the successes of SMCRA while avoiding its implementations snags.

Résumé :
<p><strong>Abstrak</strong>. Lahan bekas tambang timah berpeluang untuk dimanfaatkan sebagai areal pertanian dalam upaya pemenuhan kebutuhan pangan dan mengatasi persoalan lingkungan pasca penambangan. Tujuan makalah ini adalah untuk mengkaji upaya reklamasi lahan bekas tambang timah untuk dijadikan areal pertanian di Kepulauan Bangka Belitung. Luas seluruh izin usaha penambangan (IUP) yang telah diterbitkan oleh pemerintah pusat dan daerah dan dimiliki oleh perseroan di darat sebesar 327.524 ha, sedangkan luas IUP di laut 183.837 ha. Aspek biofisik lahan sangat menentukan keberhasilan reklamasi lahan bekas tambang timah. Pemanfaatan lahan bekas tambang timah sebagai areal pertanian menemui sejumlah kendala biofisik lahan, seperti bentang lahan (lanskap) yang tidak beraturan, hilangnya lapisan atas tanah (top soil), rendahnya status kesuburan tanah, dan terganggunya kualitas air kolong. Selain aspek biofisik, upaya reklamasi juga patut mempertimbangkan aspek sosial ekonomi, seperti status kepemilikan lahan, pengetahuan dan keterampilan petani, dan kelayakan biaya usaha tani. Penyimpanan tanah pucuk, penataan lahan, penggunaan amelioran, pengembangan Legume Cover Crops, implementasi Integrated Farming Systems, dan perbaikan kualitas air kolong di lahan bekas tambang timah diyakini mampu meningkatkan kualitas dan daya dukung lahan bekas tambang timah untuk areal pertanian. Reklamasi lahan bekas tambang timah juga membutuhkan partisipasi aktif masyarakat, pemerintah daerah, dan perusahaan tambang timah. Kegiatan reklamasi yang mampu memberikan manfaat bagi masyarakat setempat untuk berusaha tani di lahan bekas tambang timah dapat dijadikan sebagai salah satu indikator keberhasilan reklamasi pasca penambangan.</p><p><strong>Abstract</strong>. Abandoned tin-mining lands have the potential to be used as agricultural areas in order to fulfill food demand and solve the environmental problems derived from mining activities. The purpose of this paper is to assess the reclamation measures on abandoned-tin mining areas which could be used as agricultural areas in Bangka Belitung Islands. The total areas of the mining business license (IUP) issued by the central and local government and owned by the company are 327,524 ha in inland and 183,837 ha in the sea. Biophysical aspects largely determines the success of reclamation of abandoned tin-mining areas. Utilization of abandoned-tin mining areas as agricultural areas is facing land biophysical constraints, such as undulating landscape, losses of top soil, low soil fertility status, and disruption of water quality of tin-mining pond. In addition to the biophysical aspects, reclamation efforts should also consider the socio-economic aspects, including land ownership status, knowledge and skills of farmers, and the feasibility of the cost of farming systems. Conservation of top soil, arrangement of land, development of legume cover crops, implementation of Integrated Farming Systems, and improvement of water quality in the area under the former tin mine are believed to improve the quality and carrying capacity of abandoned tin-mining areas to be used as agricultural areas. Reclamation of abandoned tin-mining areas also requires the active participation of the community, local government, and tin mining company. Reclamation activities that can provide benefits to local communities for farming in tin mined land can be used as one indicator of the success of the post-mining reclamation.</p>

Résumé :
Abandoned mine lands (AMLs), which are considered some of the most dangerous anthropogenic activities in the world, are a source of hazards relating to potentially toxic elements (PTEs). Traditional reclamation techniques, which are expensive, time-consuming and not well accepted by the general public, cannot be used on a large scale. However, plant-based techniques have gained acceptance as an environmentally friendly alternative over the last 20 years. Plants can be used in AMLs for PTE phytoextraction, phytostabilization, and phytovolatilization. We reviewed these phytoremediation techniques, paying particular attention to the selection of appropriate plants in each case. In order to assess the suitability of plants for phytoremediation purposes, the accumulation capacity and tolerance mechanisms of PTEs was described. We also compiled a collection of interesting actual examples of AML phytoremediation. On-site studies have shown positive results in terms of soil quality improvement, reduced PTE bioavailability, and increased biodiversity. However, phytoremediation strategies need to better characterize potential plant candidates in order to improve PTE extraction and to reduce the negative impact on AMLs.

Résumé :
Background. Pennsylvania, with thousands of abandoned coal mines and miles of streams polluted with acid mine drainage, has the largest domestic coal mining burden contributing to deterioration of communities. Objectives. To evaluate contextual aspects by examining associations between coal abandoned mine lands (AML) and community measures of socioeconomic deprivation, social disorganization, and physical disorder. Methods. AML exposure data from the Reclaimed Abandoned Mine Land Inventory System were used to create density, diversity, accessibility, and clustering metrics. The three community context outcome measures were comprised of 14 census variables. In community-level analyses, 10 AML variables were evaluated separately with each dimension of community context, adjusting for covariates, in communities with and without abandoned mines. Results. We observed consistent associations between higher AML burden and worse socioeconomic deprivation, negative relations with social disorganization, but no statistically significant associations with physical disorder. Six of 10 AML variables were associated with socioeconomic deprivation, many consistently exhibiting exposure-effect patterns of worse deprivation with greater AML. Conclusions. Higher AML was associated with higher socioeconomic deprivation. These results can help prioritize the use of Surface Mining Control and Reclamation Act funds and inform decisions regarding Marcellus shale drilling to prevent analogous environmental degradation and public health impacts.

Résumé :
Mining activities for mineral resources over the years have resulted in major soil damage. Due the removal process of desired mineral materials, soil textures have been destroyed, various nutrient cycles have been disturbed, and microbial communities have been altered, affecting vegetation and leading to the destruction of wide areas of land in many countries. Therefore, soil restoration of abandoned mining lands became a very important part of sustainable development strategies and also prescribed by law in several countries. The main aims of this study were to develop an ecological land restoration strategy to the degraded lands due former kaolin, quartz sand, and iron mining located in Aghireșu and Căpușu Mare in Cluj County, in the Northwestern part of Transylvania from Romania and monitor soil quality changes over 40 years. To assess the effectiveness of soil reclamation of mine lands, 30 soil profiles were examined and 450 soil samples were collected from three depths (0–20 cm, 20–50 cm, and 50–80 cm) and subjected to physical and chemical analyses, and compared for their sustainable and beneficial use. All the proposed plant covers (natural grassland, pasture cover, black locust, Norway spruce, and scots pine) significantly improved the overall soil quality with the increasing years of reclamation following various patterns. Pasture cover most significantly enhanced the soil’s microbial activity, organic carbon, nitrogen, phosphorus, and potassium content followed by natural grassland. The results of this study show that considerable changes in soil quality was reached by revegetation of these abandoned mine lands restoring their ecological integrity and self-sustainability.

Résumé :
Connectivity modeling approaches for abandoned mine lands (AML) patches are limited in post-mining landscape restoration, especially where great land use changes might be expected due to large-scale land reclamation. This study presents a novel approach combining AML patch sizes with a proximity index to characterize patch-scaled connectivity for determining the spatial positions of patches with huge sizes and high connectivity. Then this study propose a scenario-based method coupled with landscape-scale metrics for quantifying landscape-scaled connectivity, which aims at exploring the optimal reclamation scheme with the highest connectivity. Using the Mentougou District in Beijing, China, as a case study, this paper confirmed which patches should be reclaimed first to meet the predetermined reclamation numbers; then this paper tested three different reclamation scenarios (i.e., cultivated land-oriented, forest-oriented, and construction land-oriented scenarios) to describe the impact of the different development strategies on landscape connectivity. The research found that the forest-oriented scenario increased connectivity quantitatively, showing an increase in the integral index of connectivity (IIC) and other landscape-scale metrics. Therefore, this paper suggests that future land-use policies should emphasize converting AML into more forest to blend in with the surrounding land-use categories. The findings presented here can contribute to better understanding the quantitative analysis of the connectivity of AML patches at both the patch scale and the landscape scale, thus providing scientific support for AML management in mine-site rehabilitation.

Résumé :
Abstract: The environment which is a part of ecosystem is being polluted due to urbanization, rapid industrialization increased demands for resources in our day to day lives have left no resources untouched. Various anthropogenic activities such as mining and milling operations, which include grinding, screening, concentrating ores and removal of tailings, disposal of mine and mill waste water release toxic metals into the natural environment affecting the lithosphere. Reclamation is the process of restoring the environmental soundness of these distressed mine lands. It consists of governing all kinds of physical, chemical and biological inconvenience of land area or soil such as fertility, pH, microbial activities and different soil nutrient cycles that make the destructed land soil fertile. The main aim of the reclamation is to bring back the fertility of soil by increasing its N, P, K values and Carbon contents. There are various remediation technologies available for removal of heavy metal from contaminated mine soil, in this paper we have discussed in-situ remediation, physical remediation, chemical remediation and biological remediation technologies which are implemented across the globe.

Résumé :
Abandoned mine lands (AMLs) associated with past coal-mining scar Pennsylvania’s landscape with environmental and safety hazards. Reclamation projects eliminate and reduce hazards AMLs pose. Due to the large number of AMLs and limited funds, precedence is given to reclaim the most hazardous sites first. These sites are identified through an assessment process that assigns priorities to AMLs. However, priorities are out-dated and do not accurately reflect the current spatial distribution of land use and census data. This article presents a GIS methodology for the prioritization of AMLs using the process of extrapolation and focal statistics. By incorporating current assessment techniques into GIS with current land use and census data, AML priorities were reassigned to accurately reflect the current spatial landscape. Results indicate that current AML priorities assigned by the state do not accurately reflect current land use and census data and underestimate the safety hazards of many sites, including high priority sites.

Résumé :
Abandoned mines and mining-related activities typically cause environmental problems related to erosion and pollutant transport. Traditional methods of smelter reclamation plan design are hampered by the lack of data integration and by time-consuming analysis. The proposed spatial decision-support system will minimize these problems as data integration and analysis are offered within one computerized environment. A geographical information system (GIS), remotely sensed data, erosion modeling, and multicriteria decisionmaking (MCDM) methods have been integrated to support reclamation procedures better. Integration of the digital data sources and analysis will produce more realistic, up-to-date models of damaged lands. This methodology is applicable to any number of damaged sites, including mine sites, smelter sites, widespread hazardous-waste sites, and areas negatively impacted by intense agriculture or forestry. The system has been tested at the Anaconda smelter site, an Environmental Protection Agency superfund site near Butte, Montana. The primary surficial problems are related to metal toxicity and transport. In addition to producing a description of the physical conditions at the entire site, the system provides spatial decision-support capabilities for generating and evaluating revegetation strategies for the site with the use of different priority schemes.

Résumé :
Weathering and transport of potentially acid generating material (PAGM) at abandoned mines can degrade downstream environments and contaminate water resources. Monitoring the thousands of abandoned mine lands (AMLs) for exposed PAGM using field surveys is time intensive. Here, we explore the use of Remotely Piloted Aerial Systems (RPASs) as a complementary remote sensing platform to map the spatial and temporal changes of PAGM across a mine waste rock pile on an AML. We focus on testing the ability of established supervised and unsupervised classification algorithms to map PAGM on imagery with very high spatial resolution, but low spectral sampling. At the Perry Canyon, NV, USA AML, we carried out six flights over a 29-month period, using a RPAS equipped with a 5-band multispectral sensor measuring in the visible to near infrared (400–1000 nm). We built six different 3 cm resolution orthorectified reflectance maps, and our tests using supervised and unsupervised classifications revealed benefits to each approach. Supervised classification schemes allowed accurate mapping of classes that lacked published spectral libraries, such as acid mine drainage (AMD) and efflorescent mineral salts (EMS). The unsupervised method produced similar maps of PAGM, as compared to supervised schemes, but with little user input. Our classified multi-temporal maps, validated with multiple field and lab-based methods, revealed persistent and slowly growing ‘hotspots’ of jarosite on the mine waste rock pile, whereas EMS exhibit more rapid fluctuations in extent. The mapping methods we detail for a RPAS carrying a broadband multispectral sensor can be applied extensively to AMLs. Our methods show promise to increase the spatial and temporal coverage of accurate maps critical for environmental monitoring and reclamation efforts over AMLs.

Résumé :
Former mining sites cause serious environmental problems worldwide as they are contaminated with hazardous levels of metals. Mined lands are characterized by a deserted landscape due to the lack of organic matter in soil. Research analyses confirmed that the structure of soil in abandoned surface mines has affected the occurrence of ecological processes and natural colonization of vegetation cannot take place. Moreover, phytoextraction of metals is possible only in soils with specific parameters. Previously conducted studies proposed the in situ supplementation with biochar, compost or agri-food wastes as a solution to the lack of organic carbon and nitrogen in areas affected by mining. Therefore, the main aim of this review is to investigate what improvements different organic amendments can bring to mining-impacted soils to support plant growth without affecting the bioavailability of metals. We concluded that contaminants are specific to the mining activity, while organic treatments cause the increase of soil pH, which influences, to the greatest extent, the bioavailability of metals.

Résumé :
The article shows the problems of irrigated agriculture in the Volga region at different stages of its formation, starting from the emergence of widespread irrigation in the region in 1966 and up to the present; the reasons for their occurrence identified by the author, together with his like-minded people and students, and the scientific solutions developed by them. It was established why the initial socio-economic function of land reclamation "Creation of a zone of guaranteed grain production in the Volga region" was not implemented. It has been proven that the solution to this problem could be the cultivation of dwarf non-lodging wheat varieties and the use of growth inhibitors, in particular chlorocholine chloride. To achieve high productivity of an irrigated hectare, given that irrigation changes the conditions for the growth of agricultural crops, the regional characteristics of their consumption of moisture and nutrients were studied, on the basis of which new agricultural technologies were developed and introduced. The most important problems of irrigated agriculture in the region are actively developing degradation processes: groundwater rise, secondary salinization, dehumification, soil compaction and destruction of soil structure. The objective and subjective causes of these processes, the patterns of their development in the irrigated agrolandscapes of the Volga region have been established, effective methods have been developed to prevent development and reduce the severity of degradation. Thus, it has been proven that the reduction of infiltration nutrition from the fields and the normalization of the reclamation situation on them can be achieved by using the developed differentiated irrigation regimes for crops; prevention of soil dehumification and an increase in humus content is possible only on the basis of an organo-mineral fertilizer system using the calculated doses of fertilizers determined by the proposed complex calculation method according to the predicted rotational balance of nutrients. It has been established that green manure is an effective method for preventing dehumification, reducing density and restoring soil structure. The primary reason for the development of undesirable soil-reclamation processes in the irrigated agrolandscapes of the Volga region and their low productivity is the nature of irrigated agriculture systems that is not adaptive to natural conditions. To solve this problem, a toolkit has been created for adapting regional farming systems to the environmental conditions of a particular field, which is a set of modern information technologies, including local integrated GIS monitoring and three information-advising systems for managing the water regime, potential, effective fertility and the physical component of the fertility of irrigated crops. soils. Irrigated agriculture has been and remains a very costly industry. This hinders its development, especially during economic crises. To increase the yield of vegetable crops under these conditions, low-cost technologies have been developed: irrigation regimes and systems of mineral fertilizers with drip irrigation and technologies for the use of chelated fertilizers, including types, doses, timing and methods of application. An important problem is the involvement of areas abandoned due to salinization in agriculture. To solve it, for the first time, based on the study of soil-reclamation processes occurring in waste lands, it was established under what conditions their self-reclamation is possible and a method was developed for determining the degree of salinity based on the results of geobotanical monitoring.

Résumé :
Introduction. Waste dumps of mine rocks of Novovolynsky mining area have high acidity, considerable content of various salts, namely sulfate ions. This high mineralization is caused by the movement to the water-collection points and the interaction of such water with rock dumps, and besides, on its way wastewater is enriched with products of rocks destruction (sulphates and salts of alkaline earth elements) and coal. Running through the abandoned places and accumulating mineral and mechanical impurities, such water gets new physical and chemical properties, which strongly influence the qualitative parameters of the environment. Analyzing the ecological situation caused by the wastewater pouring from technological dumps in mines № 2, 4, 9 on the investigated site it should be emphasized that at present, there is no storm sewer system on the investigated mines, therefore, rain water from the surfaces of waste heaps and industrial sites spontaneously flow down the lowlands and concentrate with mineral salts. Although it is known that there are considerable water influences in the main and preparatory mining operations, therefore, the collection of created waste water along the perimeter of existing waste heaps in the form of catchwater drains is made. Purpose. The purpose of the work is to investigate the physicochemical properties of wastewater from technological dumps in the Novovolynsk mining area. Methods. In this work chemical methods of wastewater analysis are used. Results. In all water samples, an increase in the content of ammonium salts was determined. As it is known, the main danger of pollution of the hydrosphere with ammonium salts is the saturation of water with ammonia. The content of ammonium salts above 0.1 mg/dm³ indicates pollution of water, since ammonia is the first compound formed during the decomposition of organic nitrogen-containing substances. Simultaneous presence of ammonia, nitrites and nitrates in samples of water shows a significant pollution of this water due to the oxidation of the rock in the dump and its washing-off with water. The increase in water samples of nitrite and nitrate content without the detection of ammonia indicates the isolation of the source of contamination. The content of ammonia and nitrite in water shows the constant source of pollution from the dumps. The presence of nitrates only indicates the end of mineralization processes. Excess ammonia in samples with the subsequent discharges into the river leads to ecological instability of the ecosystem in general, during the process of displacement of nitrogen-sensitive species, functional connections between all parts of the ecosystem (plants, animals, microorganisms) collapse, which leads to a violation of the self-regulation of the ecosystem. As a result of the conducted researches, significant differences in the physical and chemical composition of wastewater from the technological dumps of the Novovolynsk mining area were revealed. The chemical composition of wastewater of investigated mines is characterized by instability. Conclusion. Accumulation of toxic compounds in wastewater from technological dumps creates a significant man-made danger to the water resource potential of the state. It is also relevant to the wastewater contaminated with substances of the 2nd and 4th class of hazard, such as organic compounds of fluorine, nitrogen and radionuclide’s, which are one of the most dangerous for the hydrosphere. To prevent the hazardous effect of wastewater on the ecological state in the investigated area, it is necessary to use natural resources rationally, to conduct demineralization and remediation, vegetative reclamation of disturbed lands.

Résumé :
In the northern Netherlands, the fringes of the peat area adjacent to the salt marshes, with their well-known terp settlements, have been reclaimed and settled since the middle of the Pre-Roman Iron Age. Over time, settlement gradually expanded deeper into the peat area, until the reclaimed peat lands, like most of the salt marshes, were abandoned over the course of the Late Roman Iron Age. In the province of Friesland, two large areas with traces of these early peat reclamations have recently been researched using a combination of modern digital elevation maps and old aerial photographs dating back to the 1940s and 1950s. It proved possible to map 1100 km of former ditches and 508 possible archaeological sites, of which 453 locations had not previously been known. Further research could confirm that 135 of the 508 possible sites are sites of former settlements, of which 65 definitely back to the Pre-Roman Iron Age or the Roman Iron Age and 59 most likely or possibly date back to these periods. The remaining 354 locations still need to be researched, but based on various archaeological indicators, 176 of these could very well be sites dating back to the Pre-Roman Iron Age or Roman Iron Age. Of the mapped former ditches, 413.1 km proved to have been part of artificial drainage systems dating back to the Pre-Roman Iron Age or Roman Iron Age, and a large landscape feature could be identified as a former artificial embankment dating back to the same time period. Although much research is still needed, based on the current dataset it can be concluded that the early peat reclamations were intensively drained, densely settled and well organized. It seems very unlikely that these reclamations were only seasonally occupied, in contrast to what has been claimed by other researchers. Instead, it is much more likely the primary motive behind the early peat reclamations was the creation of an agricultural landscape that was suitable for mixed farming and inhabited year-round.

Résumé :
Introduction: There is an urgent need for reclamation of abandoned coal mine lands in Kuzbass to reduce their adverse effects on the environment. Objective: To assess risks to public health posed by air pollution associated with coal mine liquidation and land reclamation. Materials and methods: We used data on the volume of maximum permissible emissions of the abandoned coal mine area for 2019 to assess the spread and exposure to pollutants at 40 points selected on the map of the city of Prokopyevsk, Kemerovo Region, and to estimate the maximum and mean concentrations of the contaminants. The values of carcinogenic risk and risks of non-carcinogenic effects were calculated in compliance with the Russian Guidelines R 2.1.10.1920–04, Human Health Risk Assessment from Environmental Chemicals, while risks of chronic toxicity were assessed using methods by Shcherbo et al. The calculated risk values were then compared with their acceptable levels. Risks were also assessed with account for the contribution of background concentrations of chemicals. Results: The list of priority pollutants included inorganic dust containing 20–70 % SiO2, nitrogen dioxide, nitrogen oxide, sulfur dioxide, carbon (soot), carbon monoxide, and inorganic dust containing < 20 % SiO2. The estimated maximum and mean concentrations of airborne pollutants during mine reclamation activities were not exceeded at any exposure point. Hazard indices for acute exposures to pollutants exceeded the acceptable level at three points located closer to the sources. Carcinogenic risks did not exceed the level of acceptable risk at any point. Total risks of chronic toxicity were 1.2 and 1.75 times higher than acceptable at two points. Hazard indices estimated with account for the background levels of pollutants were 1.448–2.603 times higher than the acceptable level at all exposure points. The carcinogenic risk assessed taking into account the background levels was found to be acceptable. The most affected (target) critical organs and systems were respiratory organs and blood. Total risks of chronic poisoning assessed with account for background concentrations of ambient air pollutants exceeded the acceptable level by 3.15–5.40 times at all points. Conclusions: Reclamation activities have no significant effect on ambient air quality and health of the population of Prokopyevsk. Total risks of chronic toxicity and hazard indices exceed acceptable levels in residential areas located close to the reclamation site. High hazard indices and total risks of chronic toxicity established at all exposure points taking into account background concentrations of contaminants, are determined by generally poor environmental conditions in the city with the intensively developing coal industry.

Résumé :
AbstractThe highly rugged mountainous land topography of the Novorossiysk industrial agglomeration (NW Caucasus, Krasnodar Krai, Russia) and arid climate limit the restoration abilities of disturbed mine lands. Abandoned waste-rock dumps of a marl quarry occupy an area of ca. 150,000 m2 next to the cement plant, residential districts, and a commercial seaport. To assess the eco-risk, topsoil horizons of urban and mine-site Technosols and background Rendzinas were sampled and analyzed; measurements of particulate matter fractions PM1, PM2.5, PM4, and PM10 were conducted throughout the agglomeration. Fugitive dust emission from the unreclaimed marl dumps raises the PM2.5 content in the air by a factor of 2.68 on average. The high sorption capacity of the fine eluvium results in the accumulation of urban emissions by the dust and contributes to the subsequent soil pollution; the Cumulative Pollution Index of pedochemical anomalies reaches the high-risk level over the areas of up to 5 km2. Environmental threats caused by the mine dumps can be assessed more reliably by means of land zoning based on accumulated environmental damage indicators and the debris flow and waterspout risk calculation. To abate the technogenic impact caused by the mine spoils, reclamation actions must be taken including soil stabilization on sensitive sites by application of geosynthetic cover, hydroseeding of the mixture of soil improvers and seeds of herbaceous plants on the slopes, and anti-erosion plantation of cades (Juniperus oxycedrus L.) and smoke trees (Cotinus coggygria Scop.) at subhorizontal surfaces.
