The extent of this problem is so severe that both intense and moderate degradation are already affecting one-
third of the world’s soil, with extremely slow recovery, taking up to 1,000 years to create just a few centimetres
of arable soil (Iberdrola, 2021). As a non-renewable resource, soil is vital to sustaining plant life, biodiversity,
and water regulation. However, the increasing contamination of soil threatens its functionality and poses
severe risks to food security, biodiversity, and public health. This paper, therefore, examines the underlying
causes of soil pollution and its far-reaching impacts on the environment and human population, and outlines
potential strategies to mitigate its effects.
THEORETICAL FRAMEWORK
Smith and Ezzati (2005) first proposed the Environmental Risk Transition Theory in the field of environmental
health research. It draws its foundation from earlier World Health Organisation (WHO) concepts on the
changing nature of environmental risk as societies economically develop.
According to this theory, environmental risks change depending on the stages of development. At low-income
stages, communities face traditional risks such as poor sanitation, indoor air pollution, and unsafe water. As
situations of industrialisation and urbanisation improve, these environmental health risks begin to wane but are
gradually replaced with more complex modern risks like soil pollution, chemical contaminants, and industrial
wastes. The transition is one of trade-offs, with some forms of environmental health burdens being diminished;
on the other hand, they become more complicated and widespread (Smith & Ezzati, 2005). This framework
becomes truly cogent when applied to soil pollution, as it situates the problem within the spectrum of socio-
economic change. Soil pollution is not something that stands as isolated; instead, it emerges as a "modern"
environmental risk arising from industrialisation, urbanisation, and chemical-intensive agriculture. These are
just those drivers beneath which this study is nestled. By applying the theory, the analysis explains how, in
industrialising and newly industrialised countries such as Ghana, China, India, Malaysia, South Africa, Turkey,
and Brazil, economic growth brings about systemic hazards that disproportionately affect vulnerability
(Münzel et al., 2023; European Environment Agency, 2022) and increasing soil contamination. Therefore, the
theory provides a conceptual lens to link socio-economic development with the changing environmental health
burdens.
The Environmental Risk Transition Theory has been criticised for being too linear and deterministic, assuming
all societies eventually follow the same pathway from traditional to modern risks in this process. In truth,
many low- and middle-income countries face overlapping risks, where traditional exposures such as poor
sanitation co-exist with the new threats of soil and chemical contamination (Cachada et al., 2018). The
framework is also criticised for underplaying governance, inequality, and environmental justice concerns that
are instrumental in determining how risk burdens are shared among populations. (Levasseur et al., 2021).
These critiques imply one assertion: that while the theory does hold water as a framework for perceiving soil
pollution as a developmental malady, it must be applied with caution and somehow complemented by concern
for equity and sustainability.
Materials and Methods
The study employs a qualitative literature review methodology to explore and analyse soil pollution, its causes
and its impact on the environment and population. It was designed to synthesise existing scholarly work on the
subject, as proposed by Webster & Watson (2002), cited in Ofosu et al. (2020), to evaluate key themes and
provide a comprehensive understanding of the issues.
The data for the study were gathered from scholarly articles available on Google Scholar and ResearchGate, as
well as online reports and website publications related to the topic, drawing from the methods adopted by
Takyi et al. (2021) and Ofosu et al. (2020) in their various studies. The search focused on key terms such as
“soil”, “soil pollution”, “impact of soil pollution on the environment”, “impact on population”, “soil
pollutants”, and other relevant combinations. To manage the large volume of literature and ensure consistency,
the study included only works published in English, following the approach of Petticrew and Roberts (2006),
as cited in Ofosu et al. (2020).
