Assessing the impact of gold mining on forest cover in the Surinamese Amazon from 1997 to 2019: A semi-automated satellite-based approach

The Amazon rainforest has faced extensive deforestation for decades due to urban growth, agricultural expansion, logging and mining. Mining however has been relatively understudied in the Amazon. The objectives of this study were: (1) to develop an effective cloud-based classification approach coupled with an innovative semi-automated reclassification method; (2) to quantify the mining extent and its impacts on forest cover in Suriname from 1997 to 2019; and (3) to evaluate the impact of mining on the structure and health of the forest. Landsat 5 and 8 images were used for the initial land-use/land-cover classification using the classification and regression trees algorithm in Google Earth Engine. The resulting classified maps were reclassified in a semi-automated model to correct misclassifications between mining and urban pixels. The final maps were used to analyse the expansion of mining and its impacts on forest cover, structure (using the fragmentation metric effective mesh size), and forest health (using the phenology metric peak greenness). The combined approach resulted in an improvement in mining detection accuracy from 72% (65% producer, 79% user) to 89.5% (84% producer accuracy, 95% user). The results showed that mining increased from 69.4 km2 in 1997 to 431.6 km2 in 2019, an increase by 522% over 22 years, which led to 421.3 km2 of forest loss, of which 85% was due to artisanal and small-scale mining (ASGM). The loss of forest for ASGM resulted in greater fragmentation, with a decrease in effective mesh size by 122.8 km2 compared to a decrease by 83 km2 caused by industrial mining. Mining also caused a decrease in the health of the surrounding forest, with a larger decrease in peak greenness due to ASGM compared to industrial mining. The results demonstrate the potential of this approach that leverages cloud-based machine learning with a semi-automated reclassification to allow for rapid, accurate, and potentially global mining detection.

The Impact of Gold Mining on Children's Education in Lele Village District of Buru.

Gold mining also affects the education sector of local children, one of which is LeleVillage, located in Lolong Guba Sub-district, Buru Regency. This problem ispresented through qualitative research with descriptive methods that aim todescribe the conditions and situations related to the impact of waste gold mining inLele Village. The analytical methods used are participatory problem analysis andstakeholder analysis. The waste of gold mining in Lele Village is significant enoughto affect community income. However, the impact on education can be that childrenexperience a setback because children who participate in work tend to ignoreschool. When faced with economic problems, they have no choice, especially sinceworking in this waste gold mine is quick to make money. Therefore, it requires theattention of the local government as well as indigenous peoples to care aboutresolving the phenomenon of children working in mining areas, as well asschool-age people who do not continue their education.

VALIDATING AN ENVIRONMENTAL MANAGEMENT ACCOUNTING PRACTICES FRAMEWORK FOR THE GREENING OF ZIMBABWEAN GOLDMINING

The impact of gold mining on the environment remains a challenge despite its footprint being less than other mineral mining or farming. Through a comprehensive literature review, a conceptual framework was previously developed based on qualitative propositions to integrate environmental management accounting practices to address the impact of gold mining on the environment and other stakeholders. This work aims to enhance and validate our framework through interviews at mining companies and validate the resultant framework via a focus group at one of the mining companies. Some important findings from the interviews and the focus group are that government should play an active role in encouraging innovation in greening the sector, managing the environment, and providing safe water. The sector should be regulated and monitored; waste should be reduced through EMAPs, including Activity-Based Costing. Participants were less knowledgeable of other EMAPs, such as Material Flow Cost Accounting and Life Cycle Costing. Regarding sustainability, the sector’s negative impacts outweigh its positive contribution through failure to invest in greener technology. Illegal mining has further damaged the image of gold mining. Implications for theory and practice, management and policymakers are considered. Future work will involve case studies in Zimbabwean gold mines.

PENEGAKAN HUKUM TERHADAP PERTAMBANGAN EMAS TANPA IZIN (PETI) SEBAGAI UPAYA PENGENDALIAN DAMPAK LINGKUNGAN DI KECAMATAN SINTANG KABUPATEN SINTANG

Gold mining without a permit is one of the activities that results in a decrease in environmental quality, because gold mining activities use mercury to separate gold ore from rocks until the refining process. The purpose of this study is to identify and analyze the implementation of law enforcement against gold mining without a permit and controlling the environmental impact of gold mining without a permit in Sintang District, Sintang Regency. The type of research is sociological juridical. Data collection by interview and observation was then analyzed by qualitative methods. Unlicensed gold mining is caused by economic factors, education and the community feels they have the right to manage natural resources. Gold mining law enforcement without a permit applies criminal law with the imposition of fines and is still not optimal due to several constraints on the location of miners moving around, the absence of regional regulations related to PETI and community resistance. The government's efforts to control environmental impacts on water pollution from PETI activities are monitoring water quality conditions on a regular basis.

Satellite-Based Mapping of Gold-Mining-Related Land-Cover Changes in the Magadan Region, Northeast Russia

Gold mining generates major environmental impacts like landscape degradation, accumulation of waste rock dumps, and water contamination by suspended solids. Russia ranks third in the world in gold production, but the impact of gold mining has not been previously estimated for its vast northeastern part. This study provides a detailed overview of land-cover changes associated with gold mining in the Magadan region (northeast Russia) in the 21st century, where alluvial gold production has increased by a third in the last 20 years. A long-term series of Landsat and Sentinel-2 images obtained in July and August are used to compile two datasets of mining-impacted areas with totally removed vegetation for 2000–2002 and 2022. We calculated the NDVI difference and then discriminated mining-related vegetation losses from other bare areas, using additional data like the classification of landforms based on the digital surface model and the data on mining allotments. The total area of gold-mining sites was estimated as 41,206 ha in 2000–2002 and 72,602 ha in 2022, with an increase of 26,031 ha over the past 4–6 years. Moreover, this is a lower-boundary estimate, without taking into account man-made reservoirs and historical mines recovered by vegetation. The spatial distribution of mining sites has not changed significantly over the past two decades and has a maximum in the western part of the region. We found that the floodplains of the Berelekh and Debin Rivers (large tributaries of the Kolyma River) are most heavily impacted by gold mining with a removed vegetation canopy occupying 16.0% and 11.2% of their area. Along with the land degradation assessment, we found that 19,900 ha of historical gold-mining sites in the Berelekh River basin are recovered by vegetation, which is comparable in size to the areas impacted by mining over the past 20 years.

Environmental Impacts of Gold Mining—With Special Reference to South Africa

Gold mining has serious negative environmental impacts, especially due to pollution emanating from tailings storage facilities (TSFs, tailings dams, slimes dams). The most important forms of pollution from TSFs are acid mine drainage (AMD) and high levels of potentially toxic elements (PTEs). AMD arises from the high levels of pyrite in the mining ores, which become oxidised in the TSFs where the pyrite is exposed to atmospheric oxygen. The sulphate produced from oxidation of the sulphide in the pyrite dissolves in water to form sulphuric acid, a very strong acid. pH levels in the extremely low range of 3–4 are common. At such low pH the mobilities of numerous metallic PTEs present in gold mine tailings become extremely high, causing them to move into the environment in AMD. AMD acidifies soils to very low pH levels at which the mobility and plant-availability of metallic PTEs are very high, causing toxicities. Very disconcerting is that AMD and PTE pollution is in some cases continueing unabated at high rates even more than 70 years after a mine has been abandoned. Rehabilitation of TSFs to contain AMD and PTEs within them is very expensive and there seems to be reluctance to fully commit to their rehabilitation. Rehabilitation of TSFs is also extremely difficult. There does not yet seem to be any guidelines for their effective rehabilitation.

Farmers' perception of the impact of gold mining on shrinking agricultural land and their livelihood in the Asutifi-North District

Gold mining has contributed significantly to Ghana's economy and has since been extracted by both large-scale industrial miners as well as illegal artisanal and small-scale miners (ASGM). Despite its employment generation and national income contribution, gold mining has emerged as the major competitor to agriculture in terms of land use with devastating environmental effects. Consequently, there has been a surge in the practice of ASGM in Ghana over the years, particularly in the Asutifi-North District where NGGL is operational. This has led to shrinking agricultural land due to increasing ASGM in the District. Yet the complexities surrounding the symbiosis between large-scale mining, ASGM and agriculture remain unstudied. Additionally, understanding the perception of farmers on gold mining and what motivates farmers to venture into ASGM amidst farming remains unclear. In this work, we used both descriptive statistics and principal component factor analysis to examine the complexities surrounding large-scale mining, ASGM, and agriculture, and farmers' perception of mining. Multi-staged sampling comprising both purposive and random sampling techniques was employed, questionnaires were administered to 300 farmers and 5 key stakeholders were interviewed from 5 mining communities in the district. Results indicate that mining is the biggest competitor to farming in terms of land use and the increase in land lease to the large-scale gold mining firm (NGGL) over the years has resulted in to increase in illegal artisanal gold mining. Additionally, the result from the principal component factor analysis showed that among several reasons, a farmer's livelihood constitutes the single most important reason that compels farmers to venture into ASGM with a scale reliability coefficient (Cronbach's α) of 0.6276.

Impact of gold mining on the water quality of the lom river, Gankombol, Cameroon

The aim of this paper is to assess the impact of gold mining on the water quality of the Lom River at Gankombol (Adamawa Cameroon). Forty-eight (48) water samples are systematically collected during the dry and the rainy season. These water samples are characterized to determine the physico-chemical parameters, major ions and metals. A local geological study is conducted to determine the relationship between the geological units encountered and water contamination. Hydrochemical assessment, multivariate statistical analysis (MSA) and geostatistical modeling (GM) are used to assess contamination. The results indicate that the waters of the Lom River draining the gold mining site are acidic to neutral (5.3–6.9), very turbid (117–510 NTU) with high concentrations of suspended solids (22.89–471 mg/L). The mean concentrations of Fe, Pb, and As exceed the limits set by the World Health Organization (WHO) standards. Pb, As, Cd and Hg concentrations decrease in the rainy season mainly due to dilution by rainwater. The predominant water type is Ca–Mg–HCO3. This surface water is unsuitable for drinking purpose (997.5, Water Quality Index >300) with high level of metal pollution. MSA reveal strong linear correlations between EC-TDS, EC-Na+, TDS-Na+, Pb–As, Cl− –SO42- and TSS-Cd suggesting that the correlated parameters can have common origin. Finally, GM reveal that the lowest values of metals and pollution indices are found upstream of the gold mining site. The weathering of geological units encountered, mining activities and seasons have a major influence on the water quality. Therefore, it appears that decision-makers must take immediate action to decrease pollution and adopt suitable and sustainable remedial solutions.

Public Perception of the Socio-economic and Environmental Impact of Gold Mining in Buru Regency

The existence of gold mining activities in Buru Regency has a positive and negative impact on socio-economic and environmental conditions in the community. This study used a survey method with 107 respondents. The selection of respondents used purposive sampling techniques. The analysis technique uses a likert scale to see people's perceptions of the socioeconomic and environmental impacts of gold mining activities. The results showed that the community quite agreed with the existence of gold mining activities. This can be seen from the results of the data analysis obtained, where in the category of social impact perception, the total score is 1,099. That is, on the social impact of society as a whole argues in agreement. Further, in the category of economic impact, the number of scores is 1, 740. That is, on the economic impact of society as a whole argues in the agreement. In this category of environmental impact perception, a score of 1,124 was obtained. That is, on the overall environmental impact the community argues disapproval. The policy implication of the results of this study is that the management of gold mining in Buru Regency must minimize negative externalities that occur and carry out programs to strengthen the local economy, and in the long term also reclaim the former mining area.

History, Socioeconomic Problems and Environmental Impacts of Gold Mining in the Andean Region of Ecuador.

Mining in Ecuadorian territory comprises three stages of Ecuadorian history: pre-Columbian, colonial, and republican times. In its beginnings, this activity did not have regulations or a legal foundation. The first Mining Law dates back to 1830, and it has been modified until the most recent update in 2009. The Andean region consists of 10 provinces, 9 of which have registered gold concessions, the most important of which are Loja, Azuay, and in recent years, Imbabura and Pichincha, which are the provinces with the highest number of reported concessions. The objective of this study focused on analyzing the historical and current situation of Artisanal and Small-scale Mining (ASGM) and the emergence of large-scale (industrial) mining. For the elaboration of this study, different methodological techniques were used, such as literature review, field interviews, and expert judgment validation. The main findings show that the provinces of Loja, Azuay, Imbabura, and Pichincha are the most conflictive areas in the region due to the impacts caused by mining activities. In socio-economic terms, there are conflicts between inhabitants in favor and against these activities and problems associated with human health. In environmental terms, the findings suggest historical contamination of water sources by heavy metals, which has altered the surrounding aquatic and terrestrial systems. Finally, the study concludes that implementing public policies should be promoted to balance socio-economic and environmental aspects in gold mining activities in the Andean region of Ecuador, strengthening the use of new technologies and education to raise awareness of the serious effects of mining activities.

Assessment of Gold Mining Impact on the Vegetation of Itagunmodi-Igun Drainage Basin, Southwestern Nigeria from 1972–2011: A Remote Sensing

Abstract. A GIS-based Normalized Differential Vegetation Index (NDVI) was analyzed using space-based data between 1972 and 2011 as Input data. The result of the NDVI using Landsat 7 ETM+ shows clearly that the values range from 0.19 to −0.31. Mountains and highlands of the Itagunmodi-Igun area revealed stressed vegetation cover between 0.11 to −0.31. The NDVI was also performed on Landsat imageries of four different epoch: 1972, 1986, 2000, and 2010. Results showed that vegetation index ranged from −0.105 to 0.033, −0.25 to 0.480, −0.313 to 0.19 and −0.29 to 0.5 in 1972, 1986, 2000 and 2010 respectively. The analysis revealed that the study area experienced an increase in biomass between 1972 and 1986 but with some areas experiencing outright disappearance of vegetation as indicated by the lower bands of index values in 1972 (−0.105) and 1986 (−0.25). The result showed that the Basin experienced a rapid and significant increase in biomass between 2000 and 2010, as indicated by the lower bands of index values in 2000 (−0.291) and 2010 (0.5). The results of the NDVI in 1972 ranged from −0.105 to 0.033 while NDVI in 1986 ranged from −0.25 to 0.480 which indicated a significant increase in the vegetation index. The results of the NDVI in 2000 ranged from 0.291 to 0.5 also indicated a significant increase in the vegetation index. The study concluded that artisanal mining could cause land and vegetation degradation with consequent loss of biodiversity, ecological modification.

DAMPAK PENAMBANGAN EMAS TERHADAP LINGKUNGAN DI DESA TAMILOUW KECAMATAN AMAHAI, KABUPATEN MALUKU TENGAH

Natural resource management that does not pay attention to the principles of conservation of natural resources and the environment will have negative implications for environmental sustainability. With the discovery of gold on the coast of Tamiouw Village at this time, residents' activities have shifted to gold mining activities in the coastal area of Tamilouw. This study aims to determine the impact of gold mining on the physical environment in Tamilouw Village, Amahai District, Central Maluku Regency, as well as to determine the impact of gold mining on the social and economic environment of the local community. The research was conducted using non-experimental methods, namely exploratory descriptive, field observations and literature study. The results showed that gold mining carried out in Tamilouw Village uses mercury in the process of separating gold from sand, although there are also some people who carryout traditional processing. What some people are worried about is that the disposal of mercury waste is not carried out according to the required procedures, so that it will have an impact on environmental damage. The existence of mining activities does not affect the social aspects, namely education, health and age and gender; while from the economic aspect, it also contributes to increasing people's income.

A Systemic Analysis of the Environmental Impacts of Gold Mining within the Blyde River Catchment, a Strategic Water Area of South Africa

Exploratory modelling of the impact of gold mining on groundwater in a strategic water area of South Africa was undertaken. A systems dynamics (SD) model was developed to simulate the impact of gold mining on water quality, focusing on groundwater contamination risk, within the context of competing developmental priorities around water resource development and the socio-economic gains from gold mining. The model also identified interventions to minimise the impacts by the year 2040. The study area was the Blyde River Catchment (BRC), which is part of the Olifants Water Management Area in South Africa. This area is an important contributor, currently and in the future, to freshwater flows and groundwater in the Olifants River Catchment, which is one of South Africa’s most economically important catchments. The model development process included a causal loop diagram­–based problem conceptualisation, followed by the drawing of stock-flow diagrams and the determining of model parameters based on a combination of background literature, data from environmental impact assessments, and from the national Department of Water and Sanitation. The model showed the potential environmental risks of gold mine wastewater production and interventions to minimise these risks. The most effective intervention identified to reduce the risk of groundwater contamination was the development and use of synthetic-lined tailings dams. The baseline simulation result of sulphate loading of 5430 t/year can be reduced by 3070 t/year to give a simulated sulphate load of 2270 t/year in 2040 using this intervention. In comparison, the simulated wastewater recycling intervention only reduced the sulphate load to 4630 t/year and the wastewater treatment interventions to 3420 t/year. This project contributes to the exploratory modelling of an understudied region of the Olifants River Catchment that is a crucial provider of freshwater flows to the Olifants, which is threatened by increasing gold mining in the upper BRC. The SD model highlighted the importance of protecting the dolomitic aquifers in the BRC for the long term sustainability of the catchment, which is particularly important if groundwater development occurs.
