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.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils represent one of the largest terrestrial reservoirs of carbon (C) and understanding the controls on soil C cycling has important implications for climate change and soil fertility. Large uncertainties remain regarding the relative importance of environmental and edaphic factors, and the role of human activities on soil C dynamics. This is especially true in soils of the tropics, which are diverse and often less studied relative to temperate soils. This dissertation sought to address these uncertainties by looking at the effect of several different anthropogenic global change drivers on soil C across a diversity of soils in Puerto Rico. The effect of long-term experimental nitrogen enrichment on soil C content weakened over time and differed within lowland and montane forests, highlighting heterogeneity in responses at the landscape level. Natural abundance radiocarbon (14C) measurements indicated the dynamic nature of soil C in these forests, as the majority of C cycled on decadal time scales, even in mineral-associated fractions that are thought to be quite stable. In a regional study comparing controls on soil carbon turnover under different land covers across the island, soil properties related to parent material and soil weathering, including iron and aluminum concentrations and pH, had a greater influence on the distribution of C among soil fractions and their turnover rate than land cover and land use. Soil C and nitrogen (N) did not differ within a secondary forest chronosequence along a soil-weathering gradient, but C increased with soil pH. Spectroscopic and microscopic analyses of soil organic matter revealed differences in chemistry in buried soils depending on their exposure to the modern soil surface. This work emphasizes the importance of soil physical and chemical properties in influencing soil C dynamics and highlights the complex nature of interactions among human activities, natural disturbances, and soils in heterogenous landscapes.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains a collection of 14 case studies from around the globe that illustrate the impact of a range of land-use changes on the physical, chemical and biological characteristics of soils and provide a snapshot of the challenges faced in ensuring sustainable soil management in tropical and savannah environments. This book is not a comprehensive account of all the drivers of soil change in the tropics, nor does it cover all areas of the tropics. It does, however, take a broad view of the tropics, with the inclusion of studies from South Africa and the dry sub-humid tropics of the Kalahari as well as the humid tropics. Tropics are drawn from a wide geographical area including South and Central America, South East Asia, India and Africa, and the chapters have been contributed by authors from all of these areas as well as Europe, North America, Australasia and Japan. It thus provides a snapshot of a range of factors affecting soils across the globe. From this, emerges topics that can be grouped into the following themes: the effects of land-use change on soil microbial populations; urban soils, agriculture and soil contamination; and land-use effects on soil carbon and soil organic matter.

This book was released on 2019-11-23 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic carbon (SOC), a key component of the global carbon (C) pool, plays an important role in C cycling, regulating climate, water supplies and biodiversity, and therefore in providing the ecosystem services that are essential to human well-being. Most agricultural soils in temperate regions have now lost as much as 60% of their SOC, and as much as 75% in tropical regions, due to conversion from natural ecosystems to agricultural uses and mainly due to continuous soil degradation. Sequestering C can help to offset C emissions from fossil fuel combustion and other C-emitting activities, while also enhancing soil quality and long-term agronomic productivity. However, developing effective policies for creating terrestrial C sinks is a serious challenge in tropical and subtropical soils, due to the high average annual temperatures in these regions. It can be accomplished by implementing improved land management practices that add substantial amounts of biomass to soil, cause minimal soil disturbance, conserve soil and water, improve soil structure, and enhance soil fauna activity. Continuous no-till crop production is arguably the best example. These soils need technically sound and economically feasible strategies to sustainably enhance their SOC pools. Hence, this book provides comprehensive information on SOC and its management in different land-use systems, with a focus on preserving soils and their ecosystem services. The only book of its kind, it offers a valuable asset for students, researchers, policymakers and other stakeholders involved in the sustainable development and management of natural resources at the global level.
