1.1 Introduction
Deforestation is defined as the permanent removal of trees and vegetation cover from forests for non-forest uses such as agriculture, urban development, mining, and infrastructure expansion (FAO, 2020). It is a critical environmental issue that affects the earth's ecological balance, climate, and biodiversity. Forests are essential ecosystems that provide habitat for millions of species, regulate climate through carbon sequestration, maintain water cycles, and prevent soil erosion (Chazdon, 2014). The loss of forest cover through deforestation is therefore a major contributor to environmental degradation.
The impact of deforestation on the environment is multidimensional. It results in the loss of biodiversity as many plant and animal species become endangered or extinct due to habitat destruction (Achard et al., 2014). Furthermore, deforestation contributes to climate change by releasing significant amounts of carbon dioxide into the atmosphere, which increases the greenhouse effect and leads to global warming (IPCC, 2019). Changes in land cover also disrupt local weather patterns, reduce rainfall, and increase the frequency of extreme events such as floods and droughts.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
The phenomenon of deforestation has been a longstanding environmental concern, tracing back to early human civilization when forests were cleared for agriculture and settlement. According to FAO (2020), forest exploitation increased significantly during the Industrial Revolution as timber became a critical resource for construction, fuel, and industrial processes (FAO, 2020). Scholars have reported that deforestation accelerated in the 20th century, particularly in tropical regions, driven by population growth, commercial agriculture, and urban expansion (Achard et al., 2014).
Achard et al. asserted that during this period, the Amazon, Congo Basin, and Southeast Asian forests experienced extensive clearing, resulting in biodiversity loss, soil degradation, and disruption of local water cycles. Similarly, Chazdon (2014) stated that tropical forests, which harbor the majority of terrestrial species, faced unprecedented threats due to human activities, with many species becoming endangered or extinct.
Deforestation is widely recognized as a significant environmental challenge with far-reaching ecological, climatic, and socio-economic consequences. According to the Food and Agriculture Organization (FAO, 2020), deforestation involves the permanent clearing of forested areas for alternative land uses such as agriculture, urban development, and industrial activities. The FAO reported that between 2015 and 2020, the world lost approximately 10 million hectares of forest annually, highlighting the rapid pace at which natural habitats are being destroyed.
Several scholars have examined the environmental impact of deforestation. Achard et al. (2014) asserted that the loss of forests leads to significant biodiversity reduction, as the destruction of habitats causes many plant and animal species to become endangered or extinct. The authors further contended that deforestation disrupts ecological balance, leading to soil erosion, depletion of nutrients, and alteration of water cycles. In line with this, Chazdon (2014) stated that forests play a crucial role in sustaining ecological integrity by regulating climate, supporting biodiversity, and providing essential ecosystem services.
On the other hand, deforestation has been identified as a major driver of climate change. The Intergovernmental Panel on Climate Change (IPCC, 2019) affirmed that the removal of trees increases the concentration of greenhouse gases in the atmosphere, thereby intensifying global warming and altering weather patterns. Similarly, Lambin and Meyfroidt (2011) reported that deforestation accelerates land degradation and desertification, reducing soil fertility and threatening sustainable agricultural practices. Communities dependent on forest resources are particularly vulnerable, as loss of forest cover undermines livelihoods, food security, and socio-economic stability.
The impacts of deforestation are thus multidimensional, affecting environmental, climatic, and human systems simultaneously. Scholars have consistently argued that sustainable forest management, afforestation, and reforestation are critical to mitigating these effects. However, the speed of forest loss continues to outpace these interventions, emphasizing the urgent need for comprehensive strategies that integrate conservation with socio-economic development (FAO, 2020; Chazdon, 2014). This study is set against the backdrop of these concerns, seeking to evaluate the impact of deforestation on the environment, with particular focus on ecological, climatic, and socio-economic dimensions.
1.3 Statement of Problems
Investigation revealed that deforestation is a major environmental challenge affecting ecosystems, climate, and biodiversity worldwide. Rapid clearing of forests for agriculture, urbanization, and industrial activities is causing significant loss of habitats, leading to a decline in flora and fauna species diversity (FAO, 2020). On the other hand, the rate of deforestation is contributing to climate change through increased greenhouse gas emissions, as forests that previously acted as carbon sinks are removed, releasing stored carbon dioxide into the atmosphere (IPCC, 2019).
Furthermore, deforestation is intensifying land degradation and desertification in many regions. As tree cover diminishes, the soil loses its ability to retain water and nutrients, which reduces land fertility and threatens sustainable agricultural practices (Lambin & Meyfroidt, 2011). In addition, efforts to reforest and restore degraded lands are often slow and insufficient compared to the speed of forest loss, highlighting the urgent need for effective intervention strategies. It is against this backdrop that this study seeks to evaluate the impact of deforestation on the environment, examining its ecological, climatic, and socio-economic consequences while providing recommendations for sustainable forest management.
1.4 Aim and Objectives of Study
