During the Neogene – covering the last 23 Million years – the evolution of the environmental setting in Africa was subject to considerable changes. Natural shifts, slow and rapid, evidenced by modifications in palaeogeography, geodynamics, climate, and vegetation have caused repeated and strong changes of ecosystems in the lower latitudes. Using a variety of proxy data – researched and applied by many authors from numerous disciplines – an attempt is made to reconstruct African landscapes over space and time. Besides such spatio-temporal oscillations in recently humid, semi-humid, and dry areas of Africa, this volume of Palaeoecology of Africa (PoA) focuses on long term interrelationships between ecosystem dynamics and climate change, not ignoring the ever growing and ongoing influence of humans on natural ecosystems since the Quaternary. Regionally, this volume lays a strong focus on Nigeria (Niger Delta). Facing the omnipresent challenges of Global Change, an increasing number of African scientists is involved in palaeoenvironmental and palaeoclimatic research, both theoretical and applied. PoA systematically supports established as well as junior African scientists in the field of sustainable cooperation and academic capacity building. This book will be of interest to all concerned with or interested in up-to-date research on Neogene to Quaternary low latitudes ecosystem changes and their respective interpretation in the framework of natural climate and vegetation change evidenced by a variety of methods that allow to read and learn from the past by following the motto, "The geologic foretime as the key to the present, and possibly to the future." Palynologists, Geologists, Geographers, Archaeologists, and Geomorphologists will find this edition equally useful for their work.

This bibliography includes scientific articles on the Drakensberg, Maloti and Adjacent Lowlands published between 1808 and 2019. Although focusing on material appearing in accredited journals, there is such a wealth of information in the form of unpublished, yet traceable, reports, documents, presentations and dissertations, these are also included. The bibliography has two parts – a complete list arranged alphabetically, and the same references arranged in 33 different disciplines. These range from Palaeobotany with 17 entries, to Rock Art with 502 entries.

Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.

This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.

This handbook showcases an Africa-wide compendium of Stone Age archaeological sites and methodological advances that have improved our understanding of hominin lifeways and biogeography in the continent. The focal time spans the Pleistocene Epoch (c. 2.5 million–11,700 years ago) during which important human traits, such as obligate bipedalism that freed the hands to engage in creative activities, a large brain relative to body size, language, and social complexity, developed in the general forms that they are found today. The handbook is the first of its kind, and it is expected to play a significant role in human evolutionary research by: ❖ Collating the African Stone Age record, which exists in a fragmented state along the lines of national boundaries and colonial experiences. ❖ Showcasing emerging conceptual and methodological advances in African Pleistocene archaeology. ❖ Providing reference datasets for teaching and researching African prehistory. ❖ Making Africa’s Stone Age record accessible to researchers and students based in Africa who may not have access to journal publications where most new field discoveries are published. The Handbook features 128 chapters, of which 116 are site entries grouped by the host countries and presented in an alphabetical order. A number of those site-related entries examine multiple archaeological localities lumped under specific projects or study areas. The rest of the contributions deal with methodological topics, such as luminescence and radiocarbon dating, field data recovery, lithic analysis, micromorphology, and hominin fossil and zooarchaeological records of Pleistocene Africa. The introductory chapter provides an historical overview of the development of Stone Age (Paleolithic) archaeology in Africa beginning in the mid-19th century, and paleoenvironmental and chronological frameworks commonly used to structure the continent’s Pleistocene record. By making a good amount of African Stone Age literature accessible to researchers and the public, we wish to promote interest in human evolutionary research in the continent and elsewhere.

There is sufficient evidence to support the fact that climate change is occurring and that this is set to accelerate. While some scholars argue that climate change is largely due to natural changes, others postulate that anthropogenic factors are the major cause. Climate change associated with increasing levels of carbon dioxide is likely to affect developed and developing countries differentially, with major vulnerabilities occurring in low-latitude regions. This book presents research findings and case studies with the endeavour to inform policies geared towards addressing problems emanating from these changes. Climate variability raises concerns over the future of agriculture, conditions of land and water availability. Therefore, climate change amplifies many economic and social risks, as well as deterioration of the environment. At the same time, non-climatic risk factors such as economic instability, trade liberalization, conflicts and poor governance all inflict upon vulnerable communities. Key discussions in this title rest on: Climate Change in Africa: its impact on rural communities, vulnerability and adaptation to climate change, financial requirements of reducing green house gases, technological transfer and natural resources; Case Studies of Vulnerability to Climate Change and Variability in Eastern and Southern Africa: experiences of impacts and adaptation to extreme events, concrete experiences from farmers and crop production adaptation; and Challenges and Opportunities to Climate Change Adaptation: factors that influence choice of response strategies, challenges and opportunities for ecosystem-based approaches; and challenges and opportunities from the use of bio-fuels as a mitigation measure to climate change.

Humans evolved in the dynamic landscapes of Africa under conditions of pronounced climatic, geological and environmental change during the past 7 million years. This book brings together detailed records of the paleontological and archaeological sites in Africa that provide the basic evidence for understanding the environments in which we evolved. Chapters cover specific sites, with comprehensive accounts of their geology, paleontology, paleobotany, and their ecological significance for our evolution. Other chapters provide important regional syntheses of past ecological conditions. This book is unique in merging a broad geographic scope (all of Africa) and deep time framework (the past 7 million years) in discussing the geological context and paleontological records of our evolution and that of organisms that evolved alongside our ancestors. It will offer important insights to anyone interested in human evolution, including researchers and graduate students in paleontology, archaeology, anthropology and geology.
