A new study published by the African Institute for Development Policy (Afidep) has reignited a long-standing debate about the intersection of population growth and climate change. The research, which comes at a crucial time ahead of the 29th Conference of Parties (COP29) in November 2024, challenges the prevailing assumption that population growth is a secondary factor in global greenhouse gas (GHG) emissions, instead suggesting that family planning and population control must be integrated into climate action strategies.
The Prevailing Focus on High-Income Nations
For years, the global climate conversation has been dominated by the responsibility of high-income nations, whose per capita emissions and consumption patterns have contributed disproportionately to global GHG emissions. The Paris Agreement and subsequent climate summits, including COP28, have focused largely on mitigation efforts led by wealthy nations, with low-income countries expected to adapt to the impacts of climate change despite having contributed relatively little to the crisis. This has created a narrative where climate action is often framed in terms of industrial consumption and energy use in the global north, while population growth in developing countries has been considered a secondary or even irrelevant issue.
However, the Afidep study, led by Prof. Nyovani Madise, Director of Development Policy and Head of Afidep Malawi, calls for a broader perspective, one that acknowledges the role of population dynamics in shaping future emissions and environmental pressures. Madise argues that while high-income nations bear much of the current responsibility for emissions, fast-growing countries like Nigeria, Ethiopia, and the Democratic Republic of Congo—expected to see significant population increases by 2050—must also be part of the conversation.
The Role of Population Growth in Climate Change
One of the key findings of the Afidep study is that population growth in developing countries, particularly those on the verge of economic expansion, could exacerbate climate challenges in the future. Prof. Madise points out that populous countries such as India, China, and Nigeria already play a major role in global emissions, but that the evidence on the link between population growth and climate change has been mixed. While many studies have focused on consumption patterns in industrialized nations, Afidep’s research suggests that rapid population growth could lead to unsustainable development paths in low-income countries as they industrialize and urbanize.
The study challenges the dominant framework of climate action, which emphasizes mitigation efforts by high-income countries and adaptation strategies for low-income, low-emitting nations. While this approach may make sense in the short term, it is insufficient for addressing the long-term impacts of rapid population growth in the developing world. The Afidep report calls for integrating voluntary, rights-based family planning into climate strategies, arguing that addressing population growth could be a crucial component of reducing future emissions.
Voluntary Family Planning as a Climate Solution
A central argument of the study is that reducing population growth through voluntary, ethical family planning initiatives could provide a simple and effective strategy for curbing future emissions. According to the report, empowering couples to achieve their desired family size, while simultaneously addressing issues such as education, poverty, and environmental sustainability, can create a virtuous cycle that benefits both people and the planet.
“Reducing childbearing is arguably a simpler and more effective strategy for lowering emissions than overhauling consumption patterns in already industrialized nations,” Madise states. However, she is quick to emphasize that this must be done through empowering choices rather than coercion, pointing to the failures of past population control policies, such as China’s one-child policy, which were criticized for human rights violations and unintended consequences.
The Youth Factor: A Sustainable Path Forward
One of the more optimistic findings of the Afidep research is the potential role of younger populations in shaping a climate-friendly future. While older generations tend to have higher per capita energy consumption and are often resistant to changes in behavior, younger populations represent an opportunity to build a more sustainable path forward. Afidep’s study suggests that fertility intentions in these younger generations can be influenced by climate-conscious policies, leading to reduced emissions in the long term.
“Age structure matters,” the researchers argue, noting that younger people are more likely to adopt sustainable consumption patterns and embrace new technologies that can mitigate climate impacts. This demographic shift could be particularly important in regions like Sub-Saharan Africa, where the population is expected to continue growing rapidly in the coming decades.
A Critique of the Climate Justice Narrative
While Afidep’s findings align with the goals of climate justice, which emphasize the disproportionate responsibility of high-income nations to bear the financial burden of climate action, the study critiques the narrow focus of this movement. Prof. Madise and her team argue that while the responsibility of industrialized nations is undeniable, the role of population growth in developing countries cannot be overlooked.
The study warns that low-income nations, particularly those in Africa, are at risk of following the same unsustainable development paths that Western countries took during their industrialization. Rapid urbanization, land-use changes, and rising energy demands in countries like Nigeria and Ethiopia will inevitably lead to greater environmental pressures, increasing the risk of climate-induced disasters and resource scarcity.
Development Aid and Sustainable Solutions
To address these challenges, Afidep’s research calls for a rethinking of development aid priorities. Rather than focusing solely on short-term adaptation strategies, the report advocates for long-term investments in sustainable agriculture, renewable energy, and voluntary family planning initiatives. These measures, the researchers argue, could help fast-growing, low-income nations avoid the environmental pitfalls of rapid industrialization while ensuring that their populations have access to the resources they need to thrive.
“Unfortunately, the financial support required for these up-front investments has yet to materialize,” the report notes. More than 100 countries have committed to reducing their GHG emissions by 45 percent by 2030 and reaching net zero by 2050, but current trends suggest that the world is not on track to meet these targets. Without substantial financial and technological support from the global north, low-income nations will struggle to sustainably meet their food security and energy needs, leading to continued environmental degradation.
Ethical Considerations in Population Control
The idea of linking population control to climate action is not without controversy. Historically, efforts to reduce fertility rates have often been met with ethical concerns, particularly when they involve coercive measures. The Afidep study emphasizes that any population control efforts must be voluntary and rights-based, allowing individuals and families to make their own decisions about childbearing.
Past efforts to promote “population engineering” or fertility reductions, such as China’s one-child policy or India’s forced sterilization programs, were abandoned due to human rights violations and unintended consequences. Afidep’s approach focuses on empowering individuals through education, healthcare, and family planning, rather than imposing limits on fertility.
The Road Ahead: COP29 and the Future of Climate Action
The release of Afidep’s research just ahead of COP29 is expected to spark renewed discussions about how population dynamics and climate action should be integrated into global climate policies. While the debate over the role of population growth in climate change is likely to remain contentious, the study’s findings offer a fresh perspective on how voluntary, ethical family planning initiatives can contribute to a more sustainable future.
At COP29, world leaders will need to grapple with the complex challenges of reducing emissions, promoting sustainable development, and addressing the needs of rapidly growing populations. Afidep’s research provides a timely reminder that climate action must be comprehensive, addressing not only the emissions of wealthy nations but also the demographic trends that will shape our planet’s future.
