This paper reviews socioeconomic and political impacts of the extractive industry based on a global literature review. It reveals 27 different impacts (23 socio-economics and 4 political) associated with the industry. The socioeconomic impacts found in literature are: income, employment, livelihood, poverty, exports, training and skills development, community development, service access, land and assets impacts, health, security, gender, safety and accidents, education and literacy, culture, child labor, impacts on tribal people and agriculture. The 4 political impacts are children rights, corruption, human rights and human trafficking. The lack of documented impact data for several operational mines is a crucial issue highlighted in the review. Though it is a requirement for all mining companies to report data, the review reveals that this requirement is hardly adhered to. Inadequate mining monitoring is to be blamed for lack of data and documentation. The paper concludes with the need for more research to evaluate net returns to mining which should be used to determine the level of investment that should go back to the community. The need for comprehensive monitoring and results documentation is also recognised.

The soils of three fumaroles and one mining site, all with high metal content, were surveyed for the presence of metal-resistant sulfate-reducing bacteria and their potential application in the bioremediation of acid mine drainages. By means of selective soil enrichments a bacterial consortium was isolated from an Icelandic fumarole that displayed very high sulfate reduction in the presence of a mixture of 0.75 g/L of Fe, 0.20 g/L of Zn and 0.080 g/L of Cu. Under these conditions the bacterial consortium reduced 91% of the added 3.9 g/L of sulfate after 28 days, precipitating 100% of the Fe, 96% of the Zn and 97% of the Cu during the same time. Both total bacterial numbers and numbers of culturable sulfate-reducing bacteria remained unchanged when grown in media containing metals, suggesting low or absent inhibitory effects of the metals on the bacterial consortium. PCR-DGGE profiles of the sulfate reducing bacterial communities obtained from the Icelandic fumarole sample showed tha...

The maintenance of information systems is one of the greatest problems in the software life cycle. It is the most conflictive, costly, less planificable; and the process requiring the most resources. In spite of this reality, most organizations do not possess methodologies for software maintenance. These facts, key to the imperative need of controlling the maintenance process, have carried us to propose a maintenance methodology. In this paper an adjustment of the ISO/IEC 12207 standard for the processes of life cycle maintenance is presented. This methodology is being used by Atos ODS, one of the most important European consultants on software outsourcing and maintenance

The mining industry has played a significant role in the development of South Africa by being a top employer and foreign exchange earner. With the large workforce, labour unions have also emerged as an important factor that moderates how people, companies, and the government interact. In recent years, union-led mass actions have been on the limelight due to their violent nature that endangers human life, the reputation of the stakeholders, and compromises the economic contributions of the mining sector. The intent of this research was to investigate the impact of the labour unions on the mining industry in South Africa. The research was accomplished through a qualitative research approach, which involved a critical review of the literature and thematic analysis. By drawing from secondary sources, the research is able to avoid the tedious, time consuming, and expensive process of gathering primary data. The objectives of this research are reflected in the findings made. The research established that labour unions have an imperative role in dealing with issues concerning employee welfare. This involves identifying the challenges, communicating, and bargaining for better solutions to be implemented. The structure of the unions facilitates the interaction of the government, companies, workers, and the union in addressing the inherent matters that affect performance in the mining industry. Collective bargaining is the primary mode of negotiation employed, but in some cases, violation of agreement leads to industrial actions such as strikes, which are detrimental to all parties. To improve the role of labour unions in the mining sector, there is a need to address the conflicts of interest among the different parties to ensure that there is a consensus in how collective bargaining is achieved.

Coal fly ashes (CFA) are generated in large amounts worldwide. Current combustion technologies allow the burning of fuels with high sulfur content such as petroleum coke, generating non-CFA, such as petroleum coke fly ash (PCFA), mainly from fluidized bed combustion processes. The disposal of CFA and PCFA fly ashes can have severe impacts in the environment such as a potential groundwater contamination by the leaching of heavy metals and/or particulate matter emissions; making it necessary to treat or reuse them. At present CFA are utilized in several applications fields such as cement and concrete production, agriculture and soil stabilization. However, their reuse is restricted by the quality parameters of the end-product or requirements defined by the production process. Therefore, secondary material markets can use a limited amount of CFA, which implies the necessity of new markets for the unused CFA. Some potential future utilization options reviewed herein are zeolite synthesi...

Despite the poor working conditions, between 2003 and 2007 Chilean miners organised the longest and largest strikes in the country since the 1980s, obtaining one of the most important recent victories of the Latin American labour movement. This article uses this experience to illustrate the importance of the links between precarious workers and political activists. Drawing on 18 months of extensive fieldwork conducted at several mining sites in Chile, the article contends that the analysis of precarious workers' organisations needs to consider workers' access to different organisational resources, and the role that political parties' militants play in such access, particularly in the Global South.

Ecofeminism and the women in mining movement share common interests in gender and the environment. Ecofeminists have, however, ignored the experiences of women who work in mining. Equally, the women in mining movement has failed to draw... more

Comparative study of the mining policies in the eleven western, or public land, states. Qualitative factors are evaluated using cluster analysis, and clusters are analyzed for similarities and differences. Results are compared to the Fraser Institute Survey of Mining Companies. It was found that the variation in mining policy in the west can provide evidence for regulatory capture of state governments by the mining industry.

Neste texto apresentamos os conflitos pela água decorrentes da atividade mineral deflagrados pelo avanço dos agentes do neoextrativismo brasileiro na última década. A partir da análise dos dados do CEDOC-CPT, entre 2011 e 2020, identificamos o incremento em mais de sete vezes dos conflitos relacionados à água no campo brasileiro. As violações de diferentes formas de apropriações e negações do acesso aos bens hídricos recaíram sobre as populações tradicionais, em especial pescadores e ribeirinhos. Nessa década, as mineradoras assumiram o protagonismo nos conflitos pela água, com destaque para os grandes desastres sociotécnicos de barragens de mineração: as bacias do rio Doce e do rio Paraopeba e em Barcarena. Soma-se a esses o derramamento de petróleo no litoral brasileiro. Todos esses eventos vêm produzindo efeitos de grande amplitude espacial e duradouros no tempo, que não se limitam ao ano da ocorrência.

The Anthropocene has arrived riding a wave of pollution. From "forever chemicals" to oceanic garbage patches, human-made chemical compounds are seemingly everywhere. Concerned about how these compounds disrupt multiple lives and ecologies, environmental scholars, activists, and affected communities have sought to curb the causes of pollution, focusing especially on the extractive industries. In Worlds of Gray and Green, authors Sebastián Ureta and Patricio Flores challenge us to rethink extraction as ecological practice. Adopting an environmental humanities analytic lens, Ureta and Flores offer a rich ethnographic exploration of the waste produced by Chile's El Teniente, the world's largest underground mine. Deposited in a massive dam, the waste—known as tailings—engages with human and non-human entities in multiple ways through a process the authors call geosymbiosis. Some of these geosymbioses result in toxicity and damage, while others become the basis of lively novel ecologies. A particular kind of power emerges in the process, one that is radically indifferent to human beings but that affects them in many ways. Learning to live with geosymbioses offers a tentative path forward amid ongoing environmental devastation.

The industrial and small-scale mining industries have provoke serious environmental degradation in the form of deforestation, soil erosion and soil and water contamination by Hg and other heavy metals. Remote sensing and GIS technologies were used to investigate the temporal and spatial extent of environmental degradation from 1986 to 2000 in the Tarkwa mining area. While most of the study area was a healthy ecosystem in 1986, by 2001, over 60% of the land was degraded to the point where it could not be used for any commercial activity. An additional 35,000 ha of land has been polluted and remediation would be very expensive. This state of environmental degradation through mining activities was further aggravated by extreme human population encroachment of the region. This study puts into perspective the need for the government to institute strict environmental regulations to protect mining areas.

The environmental impact of arsenic and heavy metals on a 105 km2 area of the historical and recent mining site of Villa de la Paz-Matehuala, San Luis Potosí (Mexico) was evaluated. Results of soil samples reported concentrations between 19–17 384 mg kg-1 As, 15–7200 mg kg-1 Cu, 31–3450 mg kg-1 Pb and 26–6270 mg kg-1 Zn, meanwhile, the concentrations in dry stream sediment samples were found to vary between 29–28 600 mg kg-1 As, 50–2160 mg kg-1 Pb, 71–2190 mg kg-1 Cu, and 98–5940 mg kg-1 Zn. The maximum arsenic concentration in pluvial water storage ponds (265 μg L-1), near the main potential sources of pollution, exceed by 5 times the Mexican drinking water quality guideline (50 μg L-1). The arsenic concentrations in water storage ponds and stream sediments decrease as distance from the potential sources increase. A special case is the `Cerrito Blanco' area located 5 km east of Matehuala, where the highest arsenic concentration in water was found (>5900 μg L-1), exceeding by 100 times the established guideline, thus representing a severe health risk. The results suggest that arsenic and heavy metal dispersion from their pollution sources (historical and active tailings impoundments, waste rock dumps and historical slag piles), is mainly associated in this site with: (1) fluvial transportation of mine waste through streams that cross the area in W–E direction; and (2) aeolian transportation of mineral particles in SW–NE direction. Finally, control measures for pollution routes and remediation measures of the site are proposed.
