Southern Africa’s maritime interests are considerable: its oceans and ports are essential to the wealth of the region, are crucial for trade and are an important source of employment, food and energy. However, regional governments do not place sufficient attention on the Blue Economy and its potential to stimulate economic growth. Of the 17 UN Sustainable Development Goals, goal Number 14 (Life Below Water) is the least funded. Less than 1% of Official Development Assistance goes toward this goal, and even private investment and funding from philanthropic organizations is grossly inadequate to meet Africa’s blue economy needs. It is vital for the international community to face up to the challenges of Africa’s Blue Economy and start working on solutions and for southern Africa’s Blue Economy policies and goals to be expanded. Just as sustainable development green initiatives show promise, so too could Blue Economy projects and activities. Southern Africa’s rich coastal and marine resources need to be managed on both a national and regional level if they are to be used in a long-term, sustainable way. This book provides, for the first time, a concise study of the constraints and opportunities that the Blue Economy offers for southern Africa and the role that the Southern African Development Community (SADC) could play in fostering a sustainable use of its ocean and coastal resources.

Environmental Soil Chemistry, Third Edition provides an up-to-date overview of the interdisciplinary field of environmental soil chemistry. This classic text covers the fundamental principles of soil chemistry, including the inorganic and organic components of soil, soil porewater chemistry, interfacial chemical reactions between solids and dissolved ions/molecules, ion exchange, and the kinetics of the soil chemical process, such as sorption and redox. Soil acidity and salinity are also discussed. This fully updated third edition places particular emphasis on environmental reactions between clay minerals, metal oxides, and soil organic matter with heavy metals, pesticides, and industrial contaminants. This text provides the latest technological advances representing the cutting edge of the science. Completely updated throughout with new content and updated full color figures, the third edition contains expanded information on soil minerals and an increased emphasis on the coupling between chemical and biological reactions, mechanisms, and processes. This third edition provides upper-level undergraduate and graduate students in soil science with sound contemporary training in the basics of soil chemistry and applications to real-world environmental concerns. The book offers a competitive advantage for those students looking to incorporate novel, advanced tools into their research.

Understanding the mechanisms associated with metal complexes and the sequestering metal contaminants in the environment is essential for effective remediation. Heavy Metal Release in Soils describes and quantifies desorption/release kinetics and dissolution reactions in the release of heavy metals from soil. The book focuses on: New techniques - microscopic surface techniques, NMR and electrophoresis, XAFS, SFM, and time-resolved ATR-FTIR Theoretical analysis and kinetic approaches - adsorption/desorption hysteresis, competitive sorption and transport, multi-component models, speciation kinetics, isotherms and soil and metal parameters, and the role of soil properties on transport Applications - arsenic speciation and mobility in contaminated soils, modeling activity of CD, Zn, and Cu in contaminated soils, and in situ chemical immobilization A timely addition to the literature, this book highlights the desorption/release mechanisms for the purpose of resolving remediation dilemmas in contaminated environments. It gives you the added advantage of case studies at both the microscopic and macroscopic scales, and provides both experimental and numerical investigations. With contributions from an international panel of authors, Heavy Metals Release in Soils fills a gap in the current literature concerned with subsurface contaminant fate and transport processes.
