The main objective of this research is to assess the extent to which urbanization is impacting vegetation in Accra Metropolis from 2002, 2008 and 2020.
There has been a rapid urbanization growth in Ghana, according to the Ghana Statistical Service there has been an increase in the urban population from about 23% in 1960 to about approximately 44% in 2000 and there has been a further increase to about 50% in the year 2010. This abrupt change in population signifies an increase in the urban settlement.
Inevitably, urbanization is seen as an outcome of economic growth and increase in population growth. An increase in these factors exert external problems on the land cover. This increase has led to the depletion of vegetation, pollution of water bodies and poor sanitation in Ghana. The development of Ghana has neglected the long term impact of urban expansion on vegetation. Accra is noted to be an economic centre dominated by the buying and selling of goods and services on open streets. This threatens the green pastures in the city centres.

Zusammenfassung der Kapitel (Chapter Summaries)
Chapter One: Introduction: This chapter introduces the study, highlighting the rapid urbanization in Ghana and its impact on vegetation. It establishes the problem of vegetation loss in Accra due to unchecked urban expansion, particularly emphasizing the economic center's encroachment on green spaces. The research objectives and questions are clearly defined, focusing on assessing vegetation cover changes between 2002, 2008, and 2020 and the implications of urban growth. The introduction effectively frames the study's scope and relevance to other urbanizing cities in West Africa.
Chapter Two: Literature Review: This chapter explores the existing literature on the crucial role of urban vegetation. It examines the multiple benefits of urban vegetation, including its function as a carbon sink, air filter, and regulator of air temperature. It also highlights the negative socio-environmental impacts of vegetation loss, referencing studies such as Shirazi and Kazmi (2016) on Lahore, Pakistan, to underscore the global significance of the issue. The chapter sets the stage for the study by establishing the importance of urban vegetation and the negative consequences of its depletion.
Chapter Three: Study Area and Methodology: This chapter details the study area (Accra Metropolis) and the methodology employed. It describes the types of secondary data used, their sources, and the pre-processing steps involved. The chapter explains the techniques utilized for layer stacking, data processing, and analysis, laying out the technical framework for the study's data analysis and interpretation. The focus is on explaining how the data will be used to answer the research questions.
Chapter Four: Results: This chapter presents the findings of the study, focusing on the changes in vegetation cover and the proportion of available land cover over time. The core of this chapter is likely to be the statistical analysis showing how urban areas have grown at the expense of vegetation. It would also detail any correlations found between urban expansion and vegetation reduction, providing crucial quantitative data to support the study's conclusions.
