Environmental Science: Starting out

People are not autonomous individuals but connected beings. Curae ergo sum – we care, therefore we are. Relationality – which refers to the ethic and manner by which relational considerations govern decisions and institutional arrangements can take advantage of the power of connection – uncovers how social connection, across divides, moves people to act for the other. Drawing from research on empathy, social networks, and determinants of pro-social behavior, Caring, Empathy, and the Commons builds on Ostrom's Governing the Commons. It offers a different mechanism by which collective action is induced, arguing that, sometimes, the individual thinks not in terms of individual gain but in terms of the other. Developing this concept of relationality, this book explores various strands of literature and examines how this idea might be used to foster collective action around climate, species protection, fair trade, and other dilemmas of the commons.

This book explores the nature of climate change in southern Africa, its impacts on tourism and the resilience, adaptation and governance needs in various tourism operations and environments. Previous studies on climate change and tourism have mainly focused on the Global North and specific forms of tourism such as snow-based winter activities. Drawing on case studies from a wide range of countries including South Africa, Lesotho, Namibia, Botswana and Zimbabwe, this book fills this lacuna by describing and analysing the climate change and tourism nexus in the southern African context. The book begins by providing an overview of the current and estimated impacts of climate change to the tourism industry in the region, highlighting the deepening socio-economic inequities, and environmental and social injustices.

This book focuses on the politics of street trees and the institutions, actors and processes that govern their planning, planting and maintenance. This is an innovative approach which is particularly important in the context of mounting environmental and societal challenges and reveals a huge amount about the nature of modern life, of social change and political conflict. The work first provides different historical perspectives on street trees and politics, celebrating diversity in different cultures. A second section discusses street tree values, policy and management, addressing more contemporary issues of their significance and contribution to our environment, both physically and philosophically. It explores cultural idiosyncrasies and those from the point of view of political economy, particularly challenging the neo-liberal perspectives that continue to dominate political narratives.

This book explores the PhD experience as never before and provides a “survival guide” for current and prospective PhD students. The book investigates why mental health issues are so common among the postgraduate population, going beyond the statistics, looking at lived experience of both the author and as well as current PhD students, who have found balancing mental wellness with the PhD endeavour challenging.The author discusses tips and tricks she wished she had known at the start of her PhD process for managing mental health, such as managing imposter feelings, prioritising workload, and self-care strategies to help others throughout their own journey.

The processes and consequences of climate change impacts and adaptation are extremely heterogeneous, encompassing many different fields of study. Dr Martin Parry in his career has had the opportunity to explore many of these subjects with colleagues from these diverse disciplines. It was therefore natural for the Lectures in Climate Change series to continue with his colleagues contributing lectures on their specific areas of expertise related to climate change impacts and adaptation. Lectures in Climate Change is a unique combination of written text plus electronic slides that together comprise an informative and up-to-date set of presentations. The lectures have been written by top scientists in the field - many of them lead authors in the IPCC.

Science has never been more important, yet science education faces serious challenges. At present, science education research only sees half the picture, focusing on how students learn and their changing conceptions. Both teaching practice and what is taught, science knowledge itself, are missing. This book offers new, interdisciplinary ways of thinking about science teaching that foreground the forms taken by science knowledge and the language, imagery and gesture through which they are expressed. This book brings together leading international scholars from Systemic Functional Linguistics, a long-established approach to language, and Legitimation Code Theory, a rapidly growing sociological approach to knowledge practices.

The focus of this book is on the key water-related vulnerabilities to climate change in Africa, particularly in its most vulnerable areas, exploring potential management responses to such vulnerabilities. The African countries are particularly exposed and vulnerable to the negative impacts of climate change, with important impacts on water resources and hydrological systems, water availability, water resource management and sea level variations. Already, under various anthropogenic pressures, the status of water resources in Africa has been changing over the past decades, with decreasing water quality, falling groundwater levels, and variability in rainfall, both in terms of timing and intensity.

This book offers the reader a deeper understanding of the eThekwini Metropolitan Municipality's green and ecological infrastructure policy landscape. The author utilises the PULSE3 analytical framework to conduct an in-depth examination and to show how experts frame and implement the municipality's green and ecological infrastructure strategies and projects. Although the initial purpose of this book was to investigate the role of green and ecological infrastructures in eThekwini's water security aspirations, the author realised that climate change adaptation and mitigation play a more central role in motivating the municipality to develop and implement such science-driven projects.

Summary Our environment today faces ever greater threats from human activities, such as pollution, loss of species and habitats, and climate change. In response to this, the relatively new branch of philosophy covering environmental ethics is growing increasingly globally important. Robin Attfield shows how environmental ethics defends the independent value of living creatures, and the importance of making decisions informed by the needs and interests of future generations.
