Book excerpt: This dissertation explores the influence of land use changes on soil dynamics and functionality in tropical regions. Specifically, it addresses three main research questions. Firstly, it examines the global impact of land use changes on microbial biomass, abundance, and traits in tropical regions while identifying knowledge gaps and areas for further research in tropical microbial ecology. Secondly, it investigates how tropical secondary forest succession affects microbial function in diverse soil environments and explores the connection between changes in microbial function and soil carbon variability across different successional stages. Lastly, it aims to define a benchmark tool for soil carbon assessment in a variety of tropical climates, land use practices, and soil types, with potential applications for farmers, land managers, soil researchers, policymakers, and individuals interested in soil health assessment. The research findings underscore the significant effects of land use conversions on soil microbial communities and their associated ecosystem functions. To better understand the global-scale response of tropical regions to environmental changes, a comprehensive understanding of the diverse climates, vegetation, management practices, and soil conditions in these regions is essential. Additionally, this study examines the dynamics of microbial communities during forest succession and highlights the urgent need for further research to comprehend microbial functionalities in disturbed tropical forest soils. Furthermore, it emphasizes the importance of establishing benchmarks for assessing soil carbon in tropical soils, taking into account the impacts of land use change, and developing guidelines or protocols accordingly. This dissertation identifies knowledge gaps and suggests future research directions, including the exploration of a broader range of soil types, investigations into dry systems, examination of specific soil characteristics, and the incorporation of advanced molecular techniques. The ultimate goal of this work is to contribute to the understanding of soil dynamics, provide insights for sustainable soil management, and offer strategies for climate change mitigation in tropical regions.
