Medical Geology of Africa: A Research Primer explores the connection between geological materials and processes and human health in Africa. A synopsis on current state of knowledge is given for a selection of some of the more critical issues in African Medical Geology. Gaps in knowledge are exposed, and directions are given for navigating the most recent bibliography of the more pressing Medical Geology issues by future researchers. Guidelines for researching gaps in knowledge are prescribed and are intended for researchers eager to make urgently needed contributions towards an understanding of how judicious exploitation of the interphase between geology and health can help unravel environmental disease causality, especially of those (diseases) of unknown aetiology (DUA) which are so widespread on the African Continent.Provides a summary of current research on Medical Geology of AfricaIdentifies gaps in knowledge of the role of the geo-environment in deciphering unknown aetiologiesAssembles the most recent literature on current thematic issues, and prescribes directions of future research

Medical Geology of Africa explores the connection between geological materials, processes and the health of humans and animals. The book fosters an improved understanding of the ways in which the geological environment impacts the geographical distribution of health problems and how they contribute to better diagnoses and therapy. Africa''s unique geoenvironmental condition gives added relevance to such studies, underlining the need for geoscience and public health students and practitioners to understand new principles and applications. Chapters in the book provide extended enquiry-based investigations and examples that employ real geochemical datasets, epidemiological records, public health statistics and visualizations.- Provides a summary of current research on Medical Geology of Africa- Identifies gaps in knowledge of the role of the geo-environment in deciphering unknown aetiologies- Assembles the most recent literature on current thematic issues, and prescribes directions of future research

A Code for Geoscientific Fieldwork in Africa is the first book to focus exclusively on the important subject of geoscience and geoecology research and study, exploring the methodological considerations that engender health and safety aspects, offering strategies to mitigate these issues. This book comprises a set of guidelines to address the importance of geoscience and geoecology field trip safety, the considerations that should be taken in order to keep students, researchers and expeditionists safe in the African jungle, and how planning for safe field trips in the future should be undertaken. It also discusses how fieldwork affects the different categories of participants personally and what happens to field relationships. It gives an insightful analysis on participants with special needs and disabilities, and proven techniques for accommodating them in fieldwork. The unique challenges and obstacles faced in this kind of scientific endeavor in African settings are effectively captured in the book, including mysterious encounters with primitive bushman tribes and unavoidable dealings with belligerent local officials, and even near-fatal stampedes by rampaging wild animals. The book also incorporates by way of case histories a rich and diverse set of fieldwork experiences, insights and reflections on conducting geoscience and geoecology fieldwork in Africa, the health and safety issues that emerged, the solutions that were developed, and the realities of being in the field. Through an absorbing narrative, a paean is presented of the long and unique traditions of geoscience and geoecology fieldwork in Africa, and the reader is provided with an inside view of the trials and joys of such an endeavor. The book offers a sketch of health and safety issues that geotourists too may face during geoscience and geoecology field expeditions and proffers measures to mitigate these. The science is accessibly laid out and richly embroidered with tales of the bush. A Code for Geoscientific Fieldwork in Africa is an essential guide for both geoscience and geoecology undergraduates and postgraduate students, academics, and geotourists in Africa and from abroad embarking on mapping, mineral exploration, geoecological research and expeditions.

This book summarizes recent advances in medical geology research (past 10 years), highlighting successes and future directions. Africa's growing awareness of the link between geological factors and disease drives this rapid evolution. Despite increasing research, dedicated resources and mentors remain scarce.Recent research focuses on the circulation of both beneficial and harmful elements in the environment and their entry into the food chain, impacting human health through complex metabolic processes. Understanding these processes, like metal metabolism, is crucial for elucidating disease aetiology, particularly for poorly understood conditions. Biogeochemical factors like bioavailability and dose-response relationships are also explored, demonstrating the multidisciplinary nature of medical geology and its role in clinical diagnosis.
