Humans and the Anthropocene: a Quest for Survival and Development

In the relentless pursuit of development and survival, humans have inflicted irreparable damage on the planet, a phenomenon now encapsulated in the term "Anthropocene." This era is characterized by human activities being the predominant influence on climate and the environment (Monastersky, 2015). The extraction of resources from nature, which underpins development and sustains life, has led to mass extinctions of species, pollution of water bodies, atmospheric alterations, land degradation, and other irreversible impacts. These consequences underscore the intricate interdependence of all life forms, akin to the mutual exchange of oxygen and carbon dioxide between plants and humans.

The extinction of one species can catalyze the demise of others. In this essay, I will explore the profound impacts of human-induced environmental changes, particularly focusing on the African continent, and argue for urgent action to mitigate these effects, emphasizing the need for global compliance with international environmental protocols.

The Devastating Impact of Resource Extraction

One glaring example of environmental degradation is the rampant extraction of minerals, which has wreaked havoc on ecosystems. In Ghana, the illegal gold mining activity known as "Galamsey" epitomizes this destructive trend. The unregulated excavation of land not only destroys forests but also leaves treacherous open pits, posing lethal risks to humans and animals alike. The process further pollutes water bodies with harmful chemicals, rendering them unsafe for consumption and threatening aquatic life. In 2017, the Ghanaian government undertook significant measures to curb Galamsey, recognizing that continued degradation could eventually necessitate the importation of potable water, a dire scenario for a nation rich in natural resources.

Climate Change: A Global Responsibility

Climate change represents a critical phase of the Anthropocene. Developed countries, including Europe, North America, and Japan, are major contributors to greenhouse gas emissions due to industrial activities (Ziervogel, 2008). The advancements in technology and industrialization have resulted in substantial emissions of carbon gases, contributing to air pollution and climate change (IPCC, 2007). Ironically, developing countries, which contribute minimally to these emissions, bear the brunt of climate change's consequences. The African continent, with its extensive lands in warm climates, is particularly vulnerable (Fleshman, 2007; Pereira, 2017). This essay delves into the factors affecting climate change in Africa and argues for a collective international effort to address this global crisis.

Climate Change in Africa: Challenges and Adaptation

The African continent has experienced a temperature rise of 0.5 degrees Celsius, with projections indicating an increase of up to 2 degrees by the century's end (Shepard, 2017; Pereira, 2017). The past two decades have seen rising temperatures in Northern and Southern Africa, with East African countries like Ethiopia, Kenya, South Sudan, and Uganda reporting similar trends over fifty years (Niang et al., 2014). Although the precise future consequences of climate change remain uncertain (IPCC, 2007), the activities of developed nations continue to exacerbate the problem, compelling Africa to adapt to these changes.

Rainfall, a critical variable for African agriculture, is increasingly unpredictable, with many agricultural systems relying heavily on rain-fed methods (Pereira, 2017). The lack of observational data adds to the uncertainty surrounding rainfall patterns. Changes in rainfall trends, such as onset, duration, and magnitude, have been observed in Botswana, Zimbabwe, and western South Africa (Niang et al., 2014). The south-western part of South Africa faces drier conditions, while the southeast experiences wetter conditions during the austral summer. However, a potential delay in the start of the rainfall season during austral spring complicates agricultural planning.

One illustrative case is the shrinking Lake Chad, which has severely impacted local fishermen who depend on it for their livelihoods. Over three decades, the lake has diminished significantly, attributed to climate-induced reductions in rainfall (Fleshman, 2007). Water scarcity is a pressing consequence of climate change in Africa, with some regions experiencing increased rainfall while others, like the Sahel, face arid conditions (Niang et al., 2014; Fleshman, 2007). These fluctuations in water supply affect agriculture, social structures, economic stability, and even security across the continent.

Conflict and Resource Scarcity

The UN Secretary-General Ban Ki-moon warned the Security Council on April 17, highlighting that "throughout human history, people have fought over natural resources." Changing weather patterns risk polarizing societies and marginalizing communities, thereby heightening the potential for conflict and violence. In Africa, water-related conflicts are already prevalent, with Darfur in western Sudan exemplifying the dire consequences of water scarcity. The struggle for access to clean water has claimed countless lives, and similar tensions loom over the River Nile, potentially involving Egypt, Sudan, and Ethiopia, as well as the Volta Lake between Ghana and Burkina Faso.

The Agricultural Dependency and Vulnerability

Agriculture dominates Africa's economy, with an average of 70 percent of the labor force engaged in this sector (UNECA, 2009). Communities heavily rely on agricultural produce and natural resources, making them particularly susceptible to climate change impacts (FAO, 2007). Not only does drought threaten agricultural productivity, but the increasing acidity of the ocean, due to its absorption of carbon dioxide, jeopardizes fish populations and quality, particularly in West Africa. Countries like Cote d'Ivoire, Ghana, Liberia, and Togo face declining fish harvests due to ocean acidification and severe coastal erosion, potentially leading to demographic shifts (Shepard, 2007).

Climate change has also reduced access to arable land. Africa's vulnerability is exacerbated by rapid population growth, which encroaches on productive land. Rising temperatures and erratic rainfall render many lands unsuitable for certain crops, raising food security concerns. For instance, maize, a warm-weather crop, thrives in daily temperatures above 15 degrees but not exceeding 45 degrees (FAO, 2016). As arable land diminishes and resources become scarce, forced migration becomes a reality, leading to concentrated populations and reduced agricultural output.

Global Responsibility and Mitigation

The inability to tackle persistent socioeconomic inequality in Africa further complicates climate change adaptation. Low development levels hinder the continent's capacity to withstand harsh climate conditions, as effective adaptation and mitigation require substantial financial resources (Niang et al., 2014). Adaptation involves taking appropriate measures to address climate change's negative effects (Ziervogel, 2015). Providing farmers with access to relevant information empowers them to make informed decisions, minimizing future climate-related impacts (Ziervogel, 2015). Scientists and researchers must also ensure that crucial climatic information, such as rainfall data, is accessible to farmers, enabling accurate projections and strategic planning to maintain productivity despite climate challenges (Ziervogel, 2015).

Conclusion

In conclusion, while climate change's impact may not be uniformly distributed, developed countries remain the largest contributors to greenhouse gas emissions. Yet, developing nations, particularly those in Africa, which contribute less than 4 percent to global emissions, are among the most vulnerable (IPCC, 2014; Niang et al., 2014). The international community must respond swiftly by adhering to environmental protocols like the Kyoto Protocol, which mandates emission reductions. Climate plays a vital role in agriculture and livestock farming, with water scarcity and heat stress posing significant challenges. The far-reaching impact of climate change threatens agriculture, fisheries, and food security, undermining progress in poverty alleviation and inequality reduction. Complying with the recommendations of the Intergovernmental Panel on Climate Change could mitigate the harshest effects of climate change, preserving the delicate balance of life on our planet.
