Digital tools: mining the data
An African NPO combines traditional investigative reporting techniques with data analysis and geo-mapping to help track eco-offences
Assessment of eight coal mines in Mpumalanga showed pollution of both surface and underground water resources.
South Africa has laws and processes in place that cater for public participation in the environmental impact assessments (EIAs) needed before most new developments can go ahead, including mining. The problem is that many local residents affected by these developments struggle to access critical information about what is happening – often they have to read about them in small type on notices pinned to fences and trees, or in obfuscated newspaper advertisements.
At an Editors’ Lab Hackathon in 2013, a team from Oxpeckers Investigative Environmental Journalism, a non-proﬁt organisation that combines traditional investigative reporting with data analysis and geo-mapping tools to expose eco-offences and track organised criminal syndicates in southern Africa, put together an innovative solution: build a digital app that would alert residents to developments happening in their neighbourhood. The app would enable users to search for new developments in their area, give inputs where appropriate, and register to receive alerts whenever new information became available.
This was the start of #GreenAlert, an open-source web and mobile platform that provides citizens with a simple tool to track EIAs and other land-use change notices, and that aims to stimulate public engagement, improve accountability and promote civic engagement through active citizenry. Based on the #GreenAlert project, Oxpeckers went on to build a similar initiative in the mining sector. Called #MineAlert, this app is a centralised tool for users to access, track, and share information and documents on mining applications and licences.
The ﬁrst iteration was launched in April 2016, the second in 2018 expanded the platform to map risks posed to water resources by mining activities, and the third iteration, launched in August 2019, empowers users to track and share water-use licences approved for mining. Both tools are citizen-focused, web-based apps that aim to promote transparency and an informed citizenry. Using location-based email alerts for development and mining applications, they also provide online access to important documents, such as environmental authorisations, and mining social and labour plans.
The ideal implementation of these platforms would be to update the data inputs via an API (application programming interface) linked to the relevant government departments. Oxpeckers are working on this option, and in the meantime populate the tools with data obtained under South Africa’s Promotion of Access to Information Act (PAIA), and information provided by users. Long-term impacts of the extractives industry, such as acid mine drainage, are adding to the problems of drought, water security and climate change across South Africa. Rural communities are usually the ﬁrst to experience ﬁrst- hand the negative impacts on freshwater resources.
“Since the platinum mine began operating in our area there’s been polluted water discharged into our rivers. Our livestock drink from there and are dying. Our community is angry,” tweeted one community member, Mathapelo Thobejane, during a recent #MineAlert community symposium. Most communities affected by mining have no prior knowledge that a mine is planned in their area, what the conditions of related permits such as water-use licences are, or how to go about addressing negative impacts. They often don’t know how to seek redress when things go wrong, other than to become angry.
Goals for rehabilitating derelict and ownerless mines are often not met. Water pumped out of these abandoned mines leaches heavy metals, including aluminium, cadmium, iron, and manganese, into nearby water reserves and pollutes the quality and quantity of potable water. With these risks in mind, #MineAlert partnered with South Africa’s Water Research Commission (WRC) to develop simpliﬁed, user-friendly maps that pinpoint identiﬁed strategic freshwater areas most vulnerable to mining activities. The WRC had collated data on water systems, geology, mining activity and ecosystem vulnerability around South Africa, and built models to estimate risks posed to freshwater resources.
#MineAlert translated this complex data into a series of heat-map layers that provide instant visualisations of the risks to freshwater sources and ecosystems posed by mining activities. The visualisations span all mineral provinces, with a greater level of detail in areas where mining frequently takes place. As a country that is considered to be one of the driest countries per capita in the world, South Africa depends greatly on its strategic water source areas. These are natural “water factories”, supporting growth and development needs that are often situated far away.
Strategic water source areas (SWSAs) cover just 8% of the country’s surface but supply 50% of the annual runoff, according to the WRC. They supply 50% of the population with water, 64% of the economy and about 70% of the water that is used by agriculture. Although 21 SWSAs have been identiﬁed, only 11% of them receive formal protection. The #MineAlert Mining your Water map layer, launched in August 2019, drills down into granular data on priority freshwater resources to investigate the impacts of mining on those.
It pinpoints where water-use licences granted for mining project are situated in SWSAs – and shares the conditions that apply to the licences. Knowing what conditions and guidelines mining companies should adhere to in terms of water-use regulations is a useful way of tracking and understanding the impacts of mining on water resources, and of holding the companies involved to account. The need to monitor water-use applications and licences was emphasised by a recent Oxpeckers investigation that exposed sweeping water permit violations at mines across South Africa.
Based on data shared in parliament by the Department of Water and Sanitation, the article showed a radical increase in the number of mines flouting water-use regulations.holding the companies involved to account. The data Oxpeckers uses on its digital platforms is aggregated and analysed in journalistic investigations. For example, in 2015 Oxpeckers investigated whether the mining industry in South Africa was abiding by the undertakings that companies, by law, make to rehabilitate mines that are no longer in use.
Drawing on the mining licences data shared on #MineAlert, and working with other Oxpeckers team members, journalist Mark Olalde sourced and collated data on mine closures and the ﬁnancial provisions for rehabilitation of end-of-life mines. He spent 21 months pestering government departments for information, formally submitting requests under the PAIA and travelling from pillar to post to secure the data.”Thursday mornings were for sitting in the office with a cup of freeze-dried, instant coffee,” Olalde recalls.
“#PAIAday, as I called this weekly ritual, was my method for prying as much formerly secret information as possible from the country’s Department of Mineral Resources (DMR) into the public domain. Between sips of coffee, I would call/email/pester every provincial DMR office on my list for the week.” Olalde then curated and analysed the datasets to produce a series of investigations on mine closure trust funds, ﬁnancial provisions for rehabilitation and closure certiﬁcates, starting with ‘Mine closures: What’s happening in your backyard?’.
His second investigation, ‘Coal mines leave a legacy of ruin’, revealed that since at least 2011 no large coal mines operating in South Africa had been granted closure. This means the mines have not been rehabilitated and were simply abandoned, leaving a legacy of local and global pollution. The third and ﬁnal investigation, ‘R60-billion held for mines that are never closed’ exposed “a failed system of mine closure in which there is little oversight, large mining house carry the brunt of responsibility for ﬁnancial provisions that are never used and mines that are never fully closed”.
This work on mine closures not only liberated previously unseen datasets but has been discussed during parliamentary committee meetings and has resulted in the government amending the regulations pertaining to Financial Provision for Prospecting, Exploration, Mining or Productions Operations. The revised regulations will repeal and replace the Financial Provisioning Regulations of 2015 and include changes in the calculation of ﬁnancial provisions.
The Department of Environmental Affairs is drafting new regulations to govern ﬁnancial provisions for mine closures that could fundamentally transform how clean-ups are funded. Previously governed by the Mineral and Petroleum Resources Development Act, ﬁnancial guarantees and other aspects of mine closure now fall under the National Environmental Management Act. The new regulations come with more stringent requirements for transparency, including for auditing ﬁnancial provisions, which are proposed to occur every three years and to include “independent specialists”.
Will rising temperatures make some areas uninhabitable for animals and humans? Will today’s coastal towns be under water in future? These are the type of questions scientists all over the world are trying to answer by predicting how local climates and the global climate will change over the next decades. Climate modelling is an incredibly complex science. Carefully generated algorithms that try to consider all the variables are fed into powerful computers that calculate how climates might change. The variables that influence the climate include things like how cloud cover affects sunlight penetration, how air flows over mountain ranges and across oceans, how the sun heats up different parts of land and sea at different rates, and how much pollution is in the air over different parts of the world.
Oxpeckers set about demystifying the science with ClimaTracker, a geojournalism tool that uses interactive maps and journalism to make complex climate modelling easily accessible. Its aims include working with civil society and government entities to inform vulnerable communities and to assist in strengthening their responsive capacity by reporting on both good and bad adaptive practices for building resilience.
Using heat maps based on climate modelling data generated by researchers at the Council for Scientiﬁc and Industrial Research (CSIR), ClimaTracker features a temperature timeline that shows how much average temperatures have changed and are likely to change in the future. Farming maps, based on a climate model called ACRU developed by Professor Roland Schulze at the University of KwaZulu-Natal, show how these temperature increases will affect the average yearly primary production in different parts of South Africa over the next 100 years.
Food security is one of the biggest worries associated with climate change; what do rising temperatures and changes in agricultural production mean for the average household? Oxpeckers has created the ClimaTracker Food Basket Calculator to show the costs of climate change in real terms. The tool offers a gamiﬁed user experience that brings the message home by letting users calculate and compare their average food basket costs from year to year. Users select items they are most likely to purchase in a shopping trip to get an idea of how much crop and animal product costs have increased, or decreased, over the year.
All this information is useful for journalists reporting on climate change, adaptation and food security. Again, using and linked to the data that powers the platforms, Oxpeckers created and published a series of related journalistic investigations.
Climate change: perceptions and experiences
Although nearly 60% of Africans are aware of climate change, some of the continent’s most influential countries lag behind in widespread awareness
Across the continent, African citizens have begun to witness the consequences of climate change, driven by human industrialisation and the pursuit of economic growth. Climate change is a gradual process of average climate modiﬁcation, which is what has made it difficult to track or detect based only on human personal experience. Every day we experience variations in temperature according to the time of day or season of the year. This makes it challenging for ordinary citizens to really comprehend the risks associated with a global average temperature change of 1.5 or 20C.
Factors that influence Africa’s vulnerability to climate change stem from its high dependence on natural resources, limited ﬁnancial and institutional capacity, low GDP per capita and high levels of poverty. Employment in agriculture remains high across the continent; as of 2019 an average of 44% (of total employment) was in agriculture. The graph below provides the estimates for agricultural employment for African countries that have more than 40% of total employment in agriculture. Long-term temperature and rainfall variations will have a serious impact on the livelihoods of African citizens.
Agriculture remains an important economic activity for more than half the continent and will be a sector greatly affected by climate change. In the recent Afrobarometer Round 7 (2017- 18) Survey, “climate change” was not identiﬁed as the most important problem respondents believed their government should address, although many respondents cited water supply (23%), food shortages (17%) and agriculture (9%) as urgent issues that needed to be addressed. Those responses are embedded in the issues that climate change poses for African citizens. Climate change will certainly have an impact on any developmental progress made in these areas by African governments.
Preparing for, and adapting to, the effects of climate change will require a coordinated effort across the continent. North Africa will witness a reduction in arable land and a shortening of crop-yielding seasons due to a predicted decrease in rainfall and increase in average surface temperature. Similarly, East Africa and southern Africa are regions sensitive to climate variability and most farming practices are dependent on seasonal rainfall. West Africa’s vulnerability also relates to climate-sensitive economic activities such as livestock rearing, rain-fed agriculture, ﬁsheries and forestry.
The Intergovernmental Panel on Climate Change (IPCC) predicts that, under a high-emissions scenario, land temperatures over the African continent are likely to rise faster than the global land average. National governments are well aware of the risks climate change poses for future development on the continent, but under-resourced and fragmented institutional frameworks have caused most countries on the continent to be among the least prepared to adapt to climate change, according to the Notre Dame Global Adaptation Initiative Index.
Building up resilience and capacity will require a coordinated effort by both national governments and their populations at large. Perceptions of climate change are arguably guided by national government and business rhetoric on the topic as well as by the personal experiences of ordinary citizens with regards to weather pattern variability. Afrobarometer’s Round 7 Survey conducted 45,823 interviews across 34 African countries, covering almost 80% of the continent’s population, between 2016 and 2018.
The survey included nine questions relating to climate change. The ﬁrst question asked respondents to rate climate conditions compared to a decade ago; some 48% answered “worse” or “much worse”. An overwhelming majority of respondents from Uganda (85%), Malawi (81%) and Lesotho (79%) had witnessed worse weather conditions for agricultural activities. Only 23% of Mozambicans agreed that climate conditions had worsened, but this ﬁeldwork was conducted prior to the devastating cyclones that hit the country in 2019.
Figure 3 indicates the distribution of respondents who had heard about climate change and believed they had experienced “worse” weather conditions over the past decade. Less than half of the South African citizens had heard about climate change and even fewer believed it had made weather conditions worse. Most ordinary citizens had heard of climate change, but opinions were mixed on whether it had made weather conditions worse.
Citizens were asked to rate whether extreme weather events such as drought or flooding had become “more” or “less” severe where they lived over the past decade. Almost half the respondents reported drought as being somewhat or much more severe, while 28% thought it had become less severe. Figure 4 shows the countries where drought has worsened. In early 2017 drought hit Uganda and its impact was felt most along its so- called “cattle corridors” and into its agricultural sectors. During this period, food insecurity rose to acute levels across most of the eastern and northern parts of Uganda.
The severity of flooding was similarly seen as much worse in both Uganda (73%) and Madagascar (67%), which could be closely linked to the increase in drought intensity. When examining the demographic splits for the continent, respondents living in rural areas were more likely to observe worse weather patterns than those living in urban areas. There was a similar contrast among age groups; respondents over the age of 56 were more likely to provide a more negative view of historical weather changes than the younger age groups.
Occupation also played a role in the kind of response citizens gave: six out of 10 respondents whose occupations were in agriculture, ﬁshing or forestry observed worse or much worse climate conditions over the past decade. Exposure to news from any source was also associated with higher levels of awareness. However, those who got their daily news from either the internet or social media sources were much more likely to have heard of climate change. Part of being informed about climate change is understanding the meaning of the concept itself. Citizens were asked whether climate change meant negative, positive or other changes in weather patterns and on average two-thirds associated it with negative changes in the weather.
Figure 5 indicates whether those who had said “yes” to hearing about climate change had in fact an understanding of its negative effects on weather patterns. Zimbabwe stands out in that although most of their respondents had heard of climate change, only 31% thought it might be an adverse phenomenon. Among the continent’s most politically influential countries such as Ghana, Nigeria and South Africa, only around one in four citizens had a basic awareness of climate change. Overall, Africa’s perceptions of climate change lack any uniform pattern and awareness remains as varied as its natural environment.
Many countries are experiencing changes in their weather patterns and evidence suggests these are having a dire impact on farmers and food security. Although nearly 60% of Africans are at least aware of climate change on average, some of the continent’s biggest players lag behind in widespread awareness and understanding. Collective awareness and an understanding of climate change by ordinary citizens will be crucial when governments try to adapt and mitigate its consequences for socio-economic development. Capacity building for early warning systems and mitigation strategies are important to assist those citizens who are most vulnerable to the effects of climate change.
Zimbabwe President Emmerson Mnangagwa announced during a press briefing, that his government has postponed independence day celebrations and discouraged locals from travelling to all affected countries, even though the country has no detected cases so far of the COVID-19 coronavirus, in Harare on March 17, 2020.

Amid a spiralling economic and political crisis, President Emmerson Mnangagwa addressed the people of Zimbabwe on Tuesday 4 August. His speech, although sudden – four days after his government’s violent clampdown on the July 31 citizen protests – was highly anticipated. There may have been a desperate hope in some sections of the bruised citizenry that the president would, perhaps in the remotest of ways, acknowledge their suffering and hint at atoning for the state’s brutality. However, the ‘crocodile’ neither acknowledged the legitimacy of the widespread grievances against his leadership nor took any responsibility for bringing the country to this precipice. Instead, President Mnangagwa argued that his administration “has been undermined by the divisive politics of the opposition, sanctions, cyclones, droughts and now COVID19”, and blamed widespread protests on “a few rogue Zimbabweans acting in league with foreign detractors.” The President’s speech exposed a tone deaf and intransigent government at war with its long-suffering citizens.
For the past two decades Zimbabwean citizens have engaged in diverse, valiant efforts to use every legally available avenue to expedite democratic reform. Many Zimbabwean citizens have made heroic efforts to shed light on the gross corruption and mismanagement that has characterised ZANU-PF’s rule and created a staggering man-made disaster. They are currently caught between a regime willing to go to any lengths to crackdown on dissent, the need to navigate the day-to-day difficulties of securing precarious livelihoods, and the fear of contracting COVID-19. In the face of an unrelenting regime and rising from the crushed hopes of 31 July 2020 protests, Zimbabwean citizens have grafted the #ZimbabweanLivesMatter campaign onto ‘the energy and anger of the global’ outcry that #BlackLivesMatter. Can the South African government, whose President has taken an unequivocal stance on #BlackLivesMatter continue on an indeterminate posture on the plight of its neighbour’s black lives? Their economic and political fate, as aptly observed by SAIIA CEO Elizabeth Sidiropoulos, is intertwined with its own and that of the region.
South Africa is ideally placed to push for change in Zimbabwe, with the two countries sharing many social, political, and economic ties. South Africa remains one of the country’s most important trading partners. Zimbabwe imports 40 percent of its total imports and exports 75 percent of its total exports to South Africa. However, despite the countries’ growing stake in each other’s fates, South Africa’s response to the deepening crisis across the Limpopo leaves much to be desired. Zimbabwe is now considered one of the four most food-insecure countries in the world, alongside Yemen, Somalia and South Sudan. More than 60 percent of Zimbabwe’s 15.6 million people are considered food insecure. Around one in three children under 5 years old suffer from stunted growth as a result of chronic malnutrition. The country has the highest inflation rate in the world at around 800 percent, and the International Monetary Fund (IMF) projects economic contraction of 10.4 percent in 2020, following a 12.8 percent contraction in 2019.
The healthcare system has collapsed, and every day Zimbabwean citizens face persistent fuel shortages and rolling blackouts. The number of Zimbabweans using illegal entry points along the Limpopo River to access medical services and basic commodities has dramatically increased in recent weeks, heightening the chances of cross-border transmission of COVID-19 in both directions. As many desperate Zimbabweans will make the dangerous journey south, the South African government is poorly prepared to deal with an escalating migrant crisis. The country is wrestling with its own record unemployment levels. Increasingly, regional integration and the flow of people, commodities, knowledge and information means that insecurity anywhere is a threat to security everywhere, challenging the principle of non-interference which has guided foreign relations between southern African states and become institutionalized in the Southern African Development Community (SADC). Decades of non-interference, liberation politics, and ‘quiet diplomacy’ on behalf of the ANC has simply allowed a political and military elite in Zimbabwe to plunder the country’s resources, undermine democracy, and create an economic crisis with implications for the wider Southern African region.
A more urgent and concrete stance is imperative. It is befitting therefore that after what had seemed like another bout of silence, the Government of South Africa, through the Department of International Relations and Cooperation (DIRCO) ‘noted with concern the reports related to human rights violations in the Republic of #Zimbabwe’. However, from the Mbeki to Zuma administrations, this political gesturing is well-worn. Building on #ZimbabweanLivesMatter, a campaign that has attracted resounding regional and international intervention calls from ordinary citizens, celebrities, politicians, diplomats and multi-lateral institutions alike, it is now ‘easier for SA and the SADC to begin a meaningful engagement with all stakeholders’. But will they? South Africa in particular has an opportunity as a strategic arbiter to harness all these voices across multiple platforms that can begin the work of persuading stakeholders to come to the negotiating table. It is time for the South African government to boldly break out of the ‘liberation war-pact’ cocoon and stand with the citizens of Zimbabwe.
DIRCO’s emphasis on government to government engagement, reported to have been initiated through a telephonic call between Dr. Naledi Pandor and her Zimbabwean counterpart Dr. Sibusiso Moyo, seems to thwart any hopes for including citizen voices. Dr. Pandor’s non-committal reference to ‘South Africa’s readiness to assist if requested’ does not imbue confidence of a radical departure from previous administrations. President Mnangagwa’s 4 August speech and Government Spokesperson Nick Mangwana’s press release (two days later) declaring reports of human rights violations as ‘false’ are not a request for assistance. South Africa now needs to build the diplomatic muscle required to crack through Harare’s hardball defence. Through the #ZimbabweanLivesMatter campaign, the Zimbabwean citizens’ request for assistance has been unambiguously echoed and clearly endorsed regionally and globally. As well noted by the Executive Director of Good Governance Africa, Chris Maroleng, ‘…it is incumbent on…especially…government… in South Africa to stand up and basically call on the government of Zimbabwe to cease and desist from such anti-democratic behaviour.’ South Africa has a unique opportunity to get it right this time. Many are ready to assist.

Carbon emissions: room to grow
There’s big potential for Africa to participate in international carbon markets given its ability to contribute to greenhouse gas mitigation

Carbon emissions trading is a market-based mechanism for trading pollution credits among countries. It includes a range of policy instruments aimed at assisting industrialised countries to achieve
their emissions targets by allowing reductions to take place where they cost the least.
The trade works in several ways: International Emissions Trading (IET), the Clean Development Mechanism (CDM), and Joint Implementation (JI). The IET system involves a scheme called “cap and trade” in which governments or intergovernmental bodies such as the European Commission (EC) hand out licences to pollute (or “carbon permits”) to major polluting industries within their boundaries.
Industries can then trade these permits with one another to meet their emissions reduction targets.
Cap-and-trade schemes are the most popular way to regulate carbon dioxide (CO2) and other emissions. The scheme’s governing body begins by setting a cap on allowable emissions. It then distributes or auctions off emissions allowances that total the cap. Member companies that do not have enough allowances to cover their emissions must either make reductions or buy another company’s spare credits. Members with extra allowances can sell them or bank them for future use. Cap- and-trade schemes can be either mandatory or voluntary.
Africa accounts for only 2% of the trading in the global carbon market. Of that 2%, South Africa and North Africa enjoy the largest portion of the projects under the Clean Development Mechanism (CDM), the main carbon market resulting from the Kyoto Protocol, with the rest of Africa contributing a paltry 0.6%. According to Oscar Reyes, a researcher with Carbon Trade Watch, these ﬁgures render Africa marginal to the carbon market, and the trade has been irrelevant to the continent’s efforts to tackle climate change. According to the World Bank, China has dominated the CDM market since its inception, accounting for about 66% of all contracted CDM supply between 2002 and 2008, and 72% of the market in 2009.
India and Brazil rank second and third on the list of sellers in terms of volumes transacted. One reason why the African carbon market is less attractive relates to how electricity is generated. Access to electricity is a major challenge across much of Africa, with less than 25% – and, in some countries, as little as 5% – of the population enjoying access to grid electricity. Thus, the World Bank has calculated that the 47 countries in sub-Saharan Africa, with a combined population of 800 million people, generate as much power as Spain, with a population of 45 million.
The lack of carbon-reduction investment opportunities in the power sector and the limited number of carbon-intensive industries outside northern Africa and South Africa implies that the rest of the continent is not well positioned to influence the direction of the debate around carbon trading. The types of projects that could deliver livelihood beneﬁts to Africans, such as renewable and other small- scale energy projects, are not “cheap” options of carbon abatement, and are therefore less likely to attract the big investors. Given the limited opportunities for expanding the carbon market in Africa through the CDM, attention has shifted to projects that can be delivered through the voluntary market.
These include improved stove and tree planting projects, which have been controversial for a variety of reasons, including the difficulties involved in verifying the offsets. According to ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university, a tree can remove seven tons of carbon dioxide from the atmosphere during its life. If so, some ﬁve billion trees would need to be planted per year to counter current emission levels globally. Moreover, planting trees to soak up carbon can have detrimental knock on effects. As Robert Jackson argued in a December 2005 presentation at Duke University in North Carolina, growing plantations of fast-growing trees uses a lot of water.
This can reduce “the water available for drinking and irrigation, and harm local aquatic ecosystems”, according to the journal Nature (December 2005). Moreover, “forest soils are saltier and more acidic, compared with other types of plant cover such as crops or grasslands”, Jackson and his colleagues found. Developing countries, particularly those in sub-Saharan Africa (SSA), remain marginalised in global carbon markets despite signiﬁcant mitigation opportunities in agriculture and forestry. However, Africa has signiﬁcant potential for renewable energy, a key driver of the carbon emissions reduction.
Yet Africa’s share of the carbon markets remains low, as already mentioned. It is puzzling, therefore, that the proponents of carbon trading continue to tout the beneﬁts it offers to the poor in Africa,
in the face of mounting evidence to the contrary. For instance, a project in the Bukaleba Forestry Reserve in Uganda, intended to offset the greenhouse gas emissions (GHGs) of a coal-ﬁred power plant to be built in Norway, clearly illustrates the conflict of interests of the offset company, host countries, and the needs of local communities.
The Ugandan government received a meagre once-off fee of $410 and an annual rent of about $4,10 for each hectare of plantation – an absurdly low lease price, given the huge carbon credits the Norwegian company (Tree Farms) was aiming to sell. The project was also responsible for evicting 8,000 people living on the land from 13 villages, depriving them of their livelihoods, and probably driving them to clear land elsewhere. Africa’s share of voluntary carbon markets is also still small, then, as compared to the rest of the world. It’s a huge shortfall considering the potential beneﬁts of carbon offset revenue for sustainable development on the continent.
However, many African countries, including Kenya, Ghana, Mozambique, Uganda and the Democratic Republic of Congo have seen a surge in international demand for offset projects in the voluntary carbon markets such as delivering clean cook stoves and water puriﬁcation devices, which are likely to increase participation in these markets (Bloomberg Energy, 2013). There are several reasons why Africa has failed in the carbon markets. Some scholars have blamed this on uncoordinated marketing efforts, as well as regulatory and policy challenges. They argue that the implementation thereof and global connections can make it a challenge for carbon trading to work.
There have also been circumstances under which baseline-and-credit CDM schemes have resulted in the maltreatment of indigenous peoples and their environment. Other scholars argue that cases of trade fraud and accounting discrepancies have hindered the development of these markets in Africa, with constraints ranging from the structure of the carbon markets themselves to the continent’s own unique situation; the perennial challenges of doing business in Africa have also affected its access to international carbon markets.
Yacob Mulugeta from the University of Surrey’s Centre of Environment and Sustainability says adequate legal and institutional frameworks are lacking, or are weak, and barriers to trade and investment, which may inhibit access to new technologies, and the high investment risks in some African countries, have also resulted in potentially lower prices for CERs. Another barrier to trade, he says, is the overall policy framework in potential host countries, which may include policies not conducive to CDM, for example high levels of taxation, high interest rates, a lack of support for foreign direct investment and uncertainties around ﬁscal policies.
Financing has also been cited as a major barrier to renewable energy and energy efficiency (RE/EE) projects, which deliver carbon emission reductions and sustainable development beneﬁts to low-developed countries in Africa. But Africa’s potential to participate in international carbon markets is large, given its ability to contribute to greenhouse gases mitigation. Its potential for renewable energy generation, climate smart agriculture and extensive forestry sector all provide huge GHG mitigation potential. There are also vast areas of low productivity land where management could be altered to increase carbon stocks and create credits.
Overcoming the challenges that hinder their exploitation could see Africa increase its ability to tap into the international carbon markets. If Africa is to beneﬁt in the carbon market, it will need to start leveraging other sources of ﬁnance, increasing its investments in renewable energy, catalysing the continent’s carbon markets by putting in place regulatory systems, and increasing public funding for seed capital for carbon reduction projects. Africa will need to develop and implement its own climate and carbon ﬁnance strategy, built on the recognition that the continent can contribute most effectively to mitigating climate change by promoting sustainable land-use practices.
Extractives: green industrialisation
The business case for greening the extractive industry is strong, especially with the growing trend of ethical investing

Everything we consume has its origins in either agriculture or the extractive industries. Our smartphones are laden with minerals and metals. Even agricultural fertilisers come from mined minerals. But the way we’ve extracted, historically, has been both ecologically and socio- economically destructive. Across many jurisdictions, mineral and hydrocarbon extraction has produced negative externalities – a divergence between private returns and social costs. In other words, it’s left holes in the ground, decimated ecosystems and imposed a healthcare burden on workers.
Acid mine drainage (AMD) in South Africa provides one example. It occurs when pyrite (fool’s gold) comes into contact with oxygenated water. The consequent oxidation process produces sulphuric acid. Pyrite is a common minor constituent in South Africa’s coal and gold ore bodies. Mining fragments these bodies and large quantities of acidic water are released into the environment, initially into the groundwater and ultimately into streams and rivers, rendering the water toxic to varying degrees. Large settlements in the Witwatersrand area now live with the risks posed by this toxic water and associated sinkhole formation.
AMD expert Terence McCarthy notes that mining has funded much of South Africa’s development, but as it enters its twilight “we are now beginning to grasp the environmental damage that the [gold mining] industry has caused and will continue to cause in the decades to come. We have also seen the impact that coal mining has had, particularly on water quality in the Olifants River system.” We must learn from these experiences and prevent further coal mining in key freshwater catchments and rivers.
Beyond AMD, a recent court settlement in the Gauteng High Court in Johannesburg awarded a total of R5 billion in compensation to mine workers afflicted by silicosis or tuberculosis contracted while mining at six of South Africa’s gold mining companies between 1965 and 2019. Had these costs appeared on the offending companies’ ﬁnancial statements, they likely would not have been offloaded onto the adjacent communities who could least afford it. Globally, estimates suggest that 24.5 deaths are attributable to each Terawatt hour of coal-ﬁred electricity produced.
Coal is a health hazard, not only to those who mine it but also to those who live near coal-burning power stations. In addition to mining’s direct negative externalities, the short-term rents generated by mining have often precipitated authoritarian consolidation, inequality, corruption and generally poor governance. Elites have captured the spoils at the expense of broad-based beneﬁt. This malaise is part of a broader problem – our economic models (and resultant activity) have ignored planetary boundaries, the limits of what our interconnected life-support systems can sustain. We are consequently at risk of inducing catastrophic climate change.
If greenhouse gas emissions are not severely curtailed, or biodiversity-killing pollution not upended, ecological disaster awaits. Global collective action is now required to change the way that we produce and consume. A major part of that new policy direction has to entail the greening of the extractive industries and the integral connection of mining to green industrialisation. Not only is this possible; it’s imperative. The business case complements the moral case. Such a reorientation would simultaneously address the negative legacy effects of mining and create sustainable links to other sectors of the economy.
The technological quest for a low-carbon economy is well underway. Transport and energy revolutions are upending old systems. Electric vehicle and renewable energy production, however, require signiﬁcant quantities of minerals and metals – double the volume currently mined, according to the World Bank. But most remaining coal and hydrocarbon deposits will have to be left in the ground, rendering the need for a “just transition” away from dirty technologies to clean ones. To support this transition, the mining industry needs to be reoriented to supplying the minerals and metals required for generating and transmitting renewable energy, for building electric vehicles, and continued inputs for other products such as smartphones and batteries.
Through the adoption of new technologies, we can mine in a less environmentally destructive manner. This would also create upstream opportunities to produce the capital equipment required for less environmentally invasive mining methods. Practically, what might this look like? To begin with, unmanned aerial vehicles (UAVs) can transform geological exploration. Sensors on UAVs can detect geothermal activity, which helps exploration ﬁrms to drill and sample only in areas where resources are indicated. In the production phase, robots can work in hazardous environments instead of people, improving mine safety considerably.
Underground deposits can be accessed through relatively minor invasion, akin to laser or “keyhole” surgery. A 2015 paper, ‘A vision of Zero Entry production Areas in Mines’ (ZEPA), co- authored by four scientists from Lulea Tekniska Universitet Institut in Sweden, proposes that in mines “all work processes should be remotely operated or automated, while special mine robots should be developed for the preventive maintenance of equipment and safe retrieval operations”.
The Kankberg Gold Mine in Sweden exemplifies the art of the possible. Boliden (the mining company), in partnership with Ericsson, ABB and Volvo “plans to eventually operate with no personnel in the mine itself”. Connecting different technologies such as a 5G wi-fi network and a Smart Ventilation system, the mine is now completely automated. The resultant process optimisation has saved 54% of the mine’s energy consumption. This represents a saving of 18 MW a year on a mine that previously consumed 34 MW a year.
In South Africa, mining consumes about 15% of the country’s national electricity supply, equivalent to roughly 5,100 MW. If the sector could reduce this demand by half, it would free up 2,550 MW from a supply-constrained grid. The industry paid 86 cents per kilowatt hour (kWh) for coal-fired power in 2017/18. A reduction of 2,550 MW a year would represent a cost saving of R2.25 million. Further cost savings would be wrought if a larger portion of power was sourced from renewables, as global procurement prices of solar PV power are now around the equivalent of 26c/kWh. Procuring renewable energy and decreasing overall demand is therefore eminently sensible business practice for the mining industry, with positive spillover beneﬁts for society and the environment.
Note that modern mines need to achieve a plant recovery rate of at least 90% to cover escalating ﬁxed costs. With declining grades and the need to mine deeper ore bodies, new methods are required to reduce rock movement, mine more selectively, and achieve quality over quantity. Motivated by these requirements, “in-place” mining and processing at the point of extraction is gaining traction. It will deliver a smaller surface footprint, reduced tailings generation and low-capital-intensive mines. Mining projects could attract ﬁnancing more easily and deliver returns more quickly than with the conventional model.
Emerging digital technologies in automated rock-face mapping, material characterisation and fragmentation analysis, and rock preconditioning can also be built into the equipment and preprogrammed for speciﬁc mines. The machines that cut hard rock are now able to identify and exploit natural rock cleavages to make cutting more efficient. Declan Vogt of the Centre for Scientiﬁc and Industrial Research (CSIR) in South Africa notes: “If rock can be cut rather than blasted, mining can become continuous, leading to process and efficiency improvements.”
Crushing technology is also becoming nimbler, making obsolete the big crushers typically required at processing plants. Employing upstream technology at the rock face, to selectively mine and pre-concentrate material for subsequent metal extraction, avoids the many negative environmental impacts usually associated with mining. In the case of copper, crushing is among the largest components of a mine’s energy consumption and greenhouse gas emissions. These can be drastically reduced by in-pit mobile crushing, which, according to research scientists Terry Norgate and Nawshad Haque, “eliminates the need for trucks by having the shovel feed the run-of-mine ore directly to a continuous and dedicated belt conveyor handling system”.
Of course, these new technologies are disruptive. Mining will become less directly labour-absorptive and more capital-intensive. But they may also result in lower cost margins and greater wealth creation, which can be allocated towards research and development initiatives that develop local upstream or side-stream capacity. As economist Ricardo Hausmann famously pointed out in 2014, Finland did not become wealthy because it turned its forests into furniture; it became wealthy because the quest for more efficient tree cutting methods produced Nokia. How? Through the development of appropriate technology.
One copper mine in Zambia is charting the way in this respect. Sentinel Mine, adjacent to Kalumbila, is a “pocket of effectiveness” – an example of how mining should and could be done. Input crushing and investments in data analysis, artiﬁcial intelligence and machine learning are already a feature. Once the ore body is depleted, the river – currently diverted – will be restored. Every effort is being made to prevent soil and water contamination. The surrounding forest, part of the ecological restoration programme funded by the mine, currently supports a sawmill and furniture-making factory. When the mine closes, the factory will continue, and the entire concession converted to a nature reserve with a ﬁve-star tourism offering.
The town itself is separated from the mine and boasts an industrial development zone, which can tap into upstream, side-stream and downstream links with mining. The business case for greening the extractive industries is strong, especially with the growing trend of ethical investing and the importance of environmental, social and corporate governance (ESG) reporting. Internalising the cost of negative externalities, it turns out, is a sound business investment
