Book Description
Groundwater resources play a vital role in the sustainability of a vast majority of communities world-wide. Various anthropogenic activities (particularly related to agriculture, mining, and other diffuse and point sources of contamination), however, pose a significant threat to the quality of groundwater resources. Once contaminants reach the aquifer, the mitigation thereof becomes expensive and often not readily possible. A proactive approach to the assessment of aquifer vulnerability to contamination, rather than a reactive approach, is thus of utmost importance for the future sustainability of our groundwater resources. This dissertation deals with the assessment of aquifer vulnerability in the Rustenburg Municipality, South Africa. The assessment of aquifer vulnerability is conducted using a well-known vulnerability index called DRASTIC within a geographical information system (GIS) environment. DRASTIC is an acronym for a set of parameters that characterize the hydrogeological setting and combined evaluated aquifer vulnerability; viz.: Depth to water level, Nett Recharge, Aquifer media, Soil media, Topography, Impact of the vadose zone, and Hydraulic Conductivity. An additional objective is to adapt the current DRASTIC model to account for the potential influence of land surface uses on groundwater resources through the incorporation of land use as a vulnerability factor. The final vulnerability map shows that the highest vulnerability aquifer rating fell within the range of moderately high vulnerable (7-8) and the addition of the land use variable did not change the highest vulnerability rating. The spatial distribution of the moderately high vulnerable areas, however, was found to vary significantly with incorporation of the land use parameter. GIS proved great compatibility with an aquifer vulnerability model such as DRASTIC.

Book Description
This book is open access under a CC BY 4.0 license. This book aims to inspire decision makers and practitioners to change their approach to climate planning in the tropics through the application of modern technologies for characterizing local climate and tracking vulnerability and risk, and using decision-making tools. Drawing on 16 case studies conducted mainly in the Caribbean, Central America, Western and Eastern Africa, and South East Asia it is shown how successful integration of traditional and modern knowledge can enhance disaster risk reduction and adaptation to climate change in the tropics. The case studies encompass both rural and urban settings and cover different scales: rural communities, cities, and regions. In addition, the book looks to the future of planning by addressing topics of major importance, including residual risk integration in local development plans, damage insurance and the potential role of climate vulnerability reduction credits. In many regions of the tropics, climate planning is growing but has still very low quality. This book identifies the weaknesses and proposes effective solutions.

Book Description
Due to many challenges (i.e. climate change, energy, water and land shortage, high demands on food, land grabbing, etc.), agriculture production potential is expected to be seriously affected; thus, increasing food insecurity and hunger in many already affected regions (especially in Africa). In this context, sustainable agriculture is highly recommended as an eco-system approach where soil, water, plants, environment and living organisms live in harmony. Innovative technologies and research should be developed to ensure sustainable agriculture and productivity using modern irrigation systems, improved varieties, improved soil quality, etc. In the meantime, the preservation of natural environment should be based on resource conservation technologies and best management practices. Sustainable Agricultural Development, not only raises the serious ethical and social issues underlying these huge environmental problems, but also aims at presenting successful experiences from all over the world in relation with sustainable farming, sustainable management of water and land resources, and innovative processes in livestock production. It also aims at providing inputs to decision making processes and encouraging the transfer of relevant know-how, technologies and expertise to different countries where similar agro-climatic conditions may exist; thus saving precious resources and promoting sustainable agricultural development as a relevant approach to tackle the food security challenge. Finally, this book focuses on the paradigmatic and policy dimensions and call for an innovative approach by analyzing the key themes in a complex and interrelated manner.

Book Description
In this wholly revised second edition, Michael Edelstein draws or iis thiffy years as a community activist tc provide a much-expanded theoretical foundation for understanding the psychosocial impacts of toxic contaminagtion. Informed by social psychological theory and an extensive survey of documented cases of toxic exposure, and enlivened by excerpts drawn from more than one thousand Interviews with victims, Contaminated Communities, Second Edition, presents, a candid portrayal of the toxic victim's experience and the key stages in the course of toxic disaster. The second edition introduces dozens of new cases and provvides expanded considerations of environmental justice, environmental racism, environmental turbulence, and environmental stigma, as well as a fully articulated theory of "lifescape." The new edition moves past the well-charted role of reactive environmentalism to explore issues for a proactivist approach that employs a "third path" of social learning, sustainable innovation, consensus building, and community empowerment.

Book Description
This edited collection examines contemporary directions in geographical research on South Africa. It encompasses a cross section of selected themes of critical importance not only to the discipline of Geography in South Africa, but also of relevance to other areas of the Global South. All chapters are original contributions, providing a state of the art research baseline on key themes in physical, human and environmental geography, and in understanding the changing geographical landscapes of modern South Africa. These contributions set the scene for an understanding of the relationships between modern South Africa and the wider contemporary world, including issues of sustainable development and growth in the Global South.

Book Description
This reports focuses on a handful of natural resources: fisheries, forestry, water, fossil fuels, metals and construction minerals, and land use. It examines the driving forces of resource consumption: population and economic growth; and the pattern of development, covering technological level, economic structure and the pattern of production and consumption. European patterns of resource use are described, in both renewable and non-renewable resources. The policy responses are outlined, including the environmental impact of the important common agricultural policy, the common fisheries policy, regional development and transport and energy policies. There is a need for more policy integration to develop a coherent and efficient policy for ensuring a more sustainable use of resources. A final section on outstanding questions illustrates the problem of differing priorities amongst the various stakeholders, and presents some of the important and controversial issues which have emerged in the debate in recent years.
