Comprehensive Framework

Changing climate conditions affect mining operations all over the world, but so far, the mining sector has focused primarily on mitigation actions. Nowadays, there exists increasing recognition of the need for planned adaptation actions. To this end, the development of a practical tool for the assessment of climate change-related risks to support the mining community is deemed necessary. In this study, a comprehensive framework is proposed for climate change multi-risk assessment at the local level customized for the needs of the mining industry. The framework estimates the climate change risks in economic terms by modeling the main activities that a mining company performs, in a probabilistic model, using Bayes’ theorem. The model permits incorporating inherent uncertainty via fuzzy logic and is implemented in two versatile ways: as a discrete Bayesian network or as a conditional linear Gaussian network. This innovative quantitative methodology produces probabilistic outcomes in monetary values estimated either as percentage of annual loss revenue or net loss/gains value. Finally, the proposed framework is the first multi-risk methodology in the mining context that considers all the relevant hazards caused by climate change extreme weather events, which offers a tool for selecting the most cost-effective action among various adaptation strategies.

Climate Change Risks

<p>Climate change poses significant challenges for many industrial activities around the world, including mining. Changes in precipitation patterns and the increasing frequency of extreme weather events can trigger severe droughts or flash floods that can easily disrupt the minerals value-chain and increase environmental pollution risks. This research focuses on evaluating climate change risks faced by the mining industry in Chile during the period 2035-2065 under the assumptions of the RCP 8.5 scenario (business as usual).  This research presents risk maps, at the national scale, based on different databases that describe the location and characteristics of the mining infrastructure and spatiotemporal analysis of daily precipitation changes between present climate conditions and future predictions. The present climate conditions are depicted by historical observations for the period 1980-2010 while the future predictions are represented by an ensemble of 34 downscaled Global Circulation Models (GCMs) from the CMIP5.  On one hand, the results show that mining operations located in northern and central Chile (Atacama, Coquimbo and Valparaiso regions), will face significant flash flood risks due to the predicted increase of extreme precipitation events for 2035-2065. On the other hand, the results suggest that mining operations located in the regions of Coquimbo, Valparaiso, Biobio, Libertador G.B.O, and Metropolitan area of Santiago are those under the most significant risks due to droughts. The results obtained in this research are part of a more comprehensive project titled “Climate Risk Atlas of Chile”, developed by the Center for Climate and Resilience Research (CR2) and the Center for Global Change of Universidad Católica de Chile (https://arclim.mma.gob.cl/), which analyses the risks of climate change for different industries of the Chilean economy.</p>

Abstract The Eastern African region is witnessing changes in climate conditions and rising sea levels due to the influences of global warming interacting with weather phenomenon such as El Nino and La Nina. These trends, as well as more intense extreme weather events, highlight the urgent need for appropriate adaptation responses at both the national and local level. This is especially the case for the numerous small islands of the region that are particularly vulnerable to climate change. This paper reports on a study that examined coping and adaptation responses to climate and non-climate stressors amongst coastal communities on two Zanzibar islands (Pemba and Unguja) in Tanzania. The study focused on three of the primary livelihood activities on the islands, namely, seaweed growing, fishing, and crop and livestock farming. Using mainly survey data, we explored the responses of farmers, fishermen, and seaweed growers to multiple shocks and stressors. We further investigated responses that were discontinued for various reasons, as well as any barriers to adaptation encountered by these communities. We found that coastal communities in both Kiuyu Mbuyuni, Pemba and Matemwe, Unguja face a range of interrelated shocks and stressors linked to their livelihood activities, some of which they were able to respond to primarily through coping strategies. However, their attempts to adapt in the longer term as well as to venture outside their traditional activities were constrained by several barriers. Some of these barriers operate beyond the individual and community capability to overcome, whilst others - like social and cultural barriers – can be addressed at the local level but need a concerted effort and political will. We draw the findings together into a conceptual framework to help unpack the implications these hold for coastal communities on the two islands. We then suggest ways to build resilience in local livelihoods and overcome barriers to climate change adaptation in the future.

This paper focuses on cultural analysis and how people are coping with new situation created by climate change in production of millet. Changes relating to climate change are observed; perceived and understood on a local level. This is an important area of study for anthropologists and it is interest of climate scientists as well. This paper is based on anthropological analysis on climate change effects on finger millet production in Argal VDC of Baglung district, West of Nepal. Millet is a staple food of people of Argal and most of Hill people of Nepal. Millet is not only staple food and associated with nutrition of people. It's also associated with rituals during production and as well as during consumption. Increasing temperature, changing rainfall patterns, extreme weather events are linked with climate change which has direct effect on life of all people but also millet production and ritual activities.

Abstract. The need for assessing the risk of extreme weather events is ever increasing. In addition to quantification of risk today, the role of aggravating factors such as high population growth and changing climate conditions do matter, too. We present the open source software CLIMADA, which integrates hazard, exposure and vulnerability to compute the necessary metrics to assess risk and to quantify socio-economic impact. The software design is modular and object-oriented, offering a simple collaborative framework and a parallelization strategy which allows for scalable computations on clusters. CLIMADA supports multi-hazard calculations and provides an event-based probabilistic approach that is globally consistent for a wide range of resolutions, suitable for whole-country to detailed local studies. This paper uses the platform to estimate and contextualize the damage of hurricane Irma in the Caribbean in 2017. Most of the affected islands are non-sovereign countries and do also rely on overseas support in case disaster strikes. The risk assessment performed for this region, based on remotely available data available shortly before or hours after landfall of Irma, proves to be close to reported damage and hence demonstrates a method to provide readily available impact estimates and associated uncertainties in real time.

Climate change is predicted to have a major impact on people’s lives with the recent extreme weather events and varying abnormal temperature profiles across the world raising concerns. The impacts of global warming are already being observed, from rising sea levels and melting snow and ice to changing weather patterns. Scientists state unequivocally that these trends cannot be explained by natural variability in climate alone. Human activities, especially the burning of fossil fuels, have warmed the earth by dramatically increasing concentrations of heat-trapping gases in the atmosphere; as these concentrations increase, the more the earth will warm. Climate change and related extreme weather events are being exacerbated sooner than has previously been considered and are already adversely affecting ecosystems and human health by increasing the burden and type of disease at a local level. Changes to the marine environment and freshwater supplies already affect significant parts of the world’s population and warmer temperatures, especially in more temperate regions, may see an increased spread and transmission of diseases usually associated with warmer climes including, for example, cholera and malaria; these impacts are likely to become more severe in a greater number of countries. This review discusses the impacts of climate change including changes in infectious disease transmission, patterns of waterborne diseases and the likely consequences of climate change due to warmer water, drought, higher rainfall, rising sea levels and flooding.

Global climate change is increasingly influencing the economic system. With the frequent occurrence of extreme weather events, the influences of climate change on the economic system are no longer limited to the agricultural sector, but extend to the industrial system. However, there is little research on the influences of climate change on industrial economic systems. Among the different sectors of the industrial economic system, the mining industry is more sensitive to the influences of climate change. Here, taking the mining industry as an example, we analyzed the influences of extreme precipitation on the mining industry using the trans-logarithm production function. In addition, the marginal output elasticity analysis method was employed to analyze the main factors influencing the mining industry. It was found that the mining investment in fixed assets, labor input, and technical progress could promote the development of the mining economy, while the extreme precipitation suppressed the growth of the mining industry. The increase in fixed asset investment and the technical progress could enhance the resistance of the mining industry to extreme precipitation, while there was no indication that labor input can reduce the influences of extreme precipitation.

Subject Outlook for the mining sector. Significance Encouraged by this year’s price increases for most of Peru’s mineral exports, the government is seeking to push ahead with plans to attract much-needed foreign investment into the mining industry. This will involve politically contentious moves to deregulate some of the cumbersome procedures that affect investors. Impacts Next year’s growth target of 4% is probably over-optimistic. Social and environmental protests will add to the costs of mining investment in Peru. Once opposition has emerged to projects, it will prove difficult to reverse. Climate change will accentuate problems of water shortage for mining operations.

Abstract There is presently overwhelming scientific consensus that global climate change is indeed occurring, and that human activities are the primary driver. An increasingly resource and carbon constrained world will continue to pose formidable challenges to major industries, including mining. Understanding the implications of climate change mitigation for the mining industry, however, remains limited. This paper presents the results of a feasibility study on the implementation of a clean development mechanism and greenhouse gases (GHGs) emission reductions in the gold mining industry. It draws upon and extends the analysis of a case study conducted on gold mining operations in Thailand. The results from the case study indicated that total GHGs emissions by company A were approximately 36,886 tons carbon dioxide equivalents (tCO2e) per annual gold production capacity that meet the eligibility criteria for small-scaled clean development mechanism (CDM) projects. The electrostatic separation process was found to release the lowest amount of GHGs, whereas comminution (i.e. crushing and grinding) generated the highest GHGs emissions. By scope, the emission from purchased electricity (scope 2) is the most significant source. Opportunities for CDM projects implementation in the gold mining sector can be found in employing energy efficiency measures. Through innovation, some technical efficiency and technological development in gold processing (i.e. high pressure grinding rolls (HPGR), vertical roller mills (VRM), gravity pre-concentration and microwave heating technologies) that have the potential to reduce energy use and also lower carbon footprint of the gold mining were further discussed. The evidence reviews found that HPGR and VRM abatement technologies have shown energy and climate benefits as electricity savings and CO2 reduction of about 8-25.93 kWh/ton ore processed and 1.8-26.66 kgCO2/ton ore processed, respectively. Implications for further research and practice were finally raised.

Carbon capture, utilisation and storage (CCUS) via mineral carbonation is an effective method for long-term storage of carbon dioxide and combating climate change. Implemented at a large-scale, it provides a viable solution to harvesting and storing the modern crisis of GHGs emissions. To date, technological and economic barriers have inhibited broad-scale utilisation of mineral carbonation at industrial scales. This paper outlines the mineral carbonation process; discusses drivers and barriers of mineral carbonation deployment in Australian mining; and, finally, proposes a unique approach to commercially viable CCUS within the Australian mining industry by integrating mine waste management with mine site rehabilitation, and leveraging relationships with local coal-fired power station. This paper discusses using alkaline mine and coal-fired power station waste (fly ash, red mud, and ultramafic mine tailings, i.e., nickel, diamond, PGE (platinum group elements), and legacy asbestos mine tailings) as the feedstock for CCUS to produce environmentally benign materials, which can be used in mine reclamation. Geographical proximity of mining operations, mining waste storage facilities and coal-fired power stations in Australia are identified; and possible synergies between them are discussed. This paper demonstrates that large-scale alkaline waste production and mine site reclamation can become integrated to mechanise CCUS. Furthermore, financial liabilities associated with such waste management and site reclamation could overcome many of the current economic setbacks of retrofitting CCUS in the mining industry. An improved approach to commercially viable climate change mitigation strategies available to the mining industry is reviewed in this paper.

The effects of climate change and associated extreme weather events such as heat, storms and heavy rainfall lead to considerable damage to property and personal injury worldwide. To counteract the causes and consequences of climate change, many states, regions and cities worldwide declared the status of climate emergency in 2019. As a result, scientists and urban planners intensified their efforts to develop appropriate mechanisms and measures to mitigate and adapt to climate change and its consequences. This paper presents an informal systematic and user-driven governance instrument, which examines the ecological, social and economic effects of urban interventions – the ‘Sustainability Check’. As a target-based assessment tool, it provides decision-makers with information about the extent to which a planned intervention corresponds with future-oriented urban development. The check results from the research project ZUKUR (‘Future of the Urban Region Ruhr’), in which researchers and practitioners from the City of Bottrop (Germany) worked together in a real-world laboratory. The Sustainability Check is novel because it combines elements of an impact assessment tailored to user needs and links sustainable urban development goals with resilient and environmentally just urban development at the local level. Based on the first application, we conclude that the Sustainability Check significantly contributes to developing a future-oriented city. Adapted to the local and context-specific needs of a city, it offers systematic consideration of the requirements of sustainable, resilient and environmentally just urban development in an efficient manner and at the early-stage.
