Thesis Abstract

Abstract
Urbanization is a global phenomenon that has transformed landscapes and ecosystems, leading to significant impacts on biodiversity. Wetland ecosystems, in particular, are highly vulnerable to the effects of urbanization due to their unique characteristics and functions. This thesis investigates the impact of urbanization on biodiversity in wetland ecosystems, focusing on understanding the changes in species diversity, community composition, and ecosystem functions in urbanized wetlands compared to natural wetlands. The study begins with a comprehensive literature review that examines the current state of knowledge on urbanization impacts on wetland biodiversity. It explores the key drivers of urbanization, the mechanisms through which urbanization affects wetland ecosystems, and the responses of biodiversity to urbanization pressures. The literature review highlights the gaps in existing research and provides a theoretical framework for the empirical investigation. The research methodology involves field surveys and data collection in both urbanized and natural wetlands to compare biodiversity metrics such as species richness, abundance, and community structure. Various sampling techniques are employed to capture the diversity of flora and fauna in wetland ecosystems, including vegetation surveys, bird counts, and aquatic invertebrate sampling. The data collected are analyzed using statistical methods to assess the differences in biodiversity between urbanized and natural wetlands. The findings of the study reveal that urbanization has a significant impact on wetland biodiversity, leading to reduced species diversity, altered community composition, and changes in ecosystem functions. Urbanized wetlands exhibit lower species richness and abundance compared to natural wetlands, with certain species being more sensitive to urbanization pressures. The study also identifies specific urbanization factors, such as habitat loss, pollution, and fragmentation, that contribute to the decline in biodiversity in wetland ecosystems. The discussion section critically evaluates the implications of the research findings for wetland conservation and management. It highlights the importance of protecting and restoring urbanized wetlands to enhance biodiversity conservation and ecosystem resilience in the face of ongoing urbanization. The study emphasizes the need for integrated land-use planning and sustainable development practices to mitigate the negative impacts of urbanization on wetland biodiversity. In conclusion, this thesis contributes to the understanding of the impact of urbanization on biodiversity in wetland ecosystems and provides valuable insights for conservation efforts. The findings underscore the importance of preserving natural wetlands and implementing effective management strategies to safeguard biodiversity in urbanized landscapes. Future research directions are suggested to further explore the complex interactions between urbanization and wetland biodiversity, with the aim of promoting sustainable urban development and biodiversity conservation.
