As atmospheric concentrations of greenhouse gases continue to increase, so does the potential for atmospheric warming and associated climate change. In an effort to address the threat of global climate change, 155 countries signed the UN Framework Convention on Climate Change at the Earth Summit in Rio de Janeiro in June 1992. As of the first session of the Conference of the Parties, 128 nations had ratified the Convention. Among their other commitments, Parties to the Convention must develop and periodically update national inventories of net anthropogenic greenhouse gas emissions using comparable methodologies, and must develop and implement national programs to mitigate greenhouse gas emissions. To further the development of emission inventories and mitigation options within the African context, 64 governmental and non-governmental scientists and policy analysts from 23 nations gathered at a workshop near Johannesburg, South Africa from 29 May to 2 June 1995. The workshop focused on forestry, land-use change, and agriculture, because these sectors not only are responsible for the majority of emissions from the continent and provide promising opportunities for emissions mitigation, but also are a vital component of African economic growth and development. This book presents the workshop's major conclusions and findings, as well as individual papers that were prepared for the workshop, each of which was peer-reviewed and accepted for publication as part of the workshop process. The papers cover four areas: (1) issues are associated with data collection and emission factor determination; (2) problems associated with applying the IPCC inventory methodologies in Africa; (3) results of national inventory assessments in Africa; and (4) possible emissions mitigation options and methods for evaluating their potential viability. As the first book dedicated solely to greenhouse gas emissions and mitigation options in Africa, this will be an invaluable resource to scientists, policymakers, and development specialists interested in global climate change and Africa.

This book provides information on the distribution of the available energy resources throughout the continent and how it is linked to the development of individual states. Africa is considered one of the poorest continents in the world, mainly because its development has historically depended on imported resources including technical expertise. This view and its associated resource management strategy are based on the perception that Africa lacks sufficient energy resources to drive its development agenda. Analyses of individual countries’ energy potentials, exploitation levels and distribution mechanisms are provided with a view to identifying additional factors that are stifling Africa’s economic development. One critical factor is the relationship between available energy resources and the energy mixes chosen by different states, and how these can be exploited to produce the right blend of energy for various applications such as industrial, transport, domestic, and recreational uses. The authors provide an in-depth analysis of the advantages and disadvantages of different energy sources in terms of their environmental, industrialization and distribution costs, impacts, and the development options best suited for improving Africa’s economic situation. This analysis is based on the assertion that Africa is indeed blessed with abundant energy resources, which have not been effectively exploited. The book not only reviews Africa’s energy situation in general, but also reveals that, while there are certainly circumstances peculiar to individual countries, the similarities, especially within Sub-Saharan African countries, outweigh the differences. That being said, the challenges and available opportunities in each country should be viewed with due consideration given to the prevailing national resource management environment. Many initiatives in Africa fail because of the many loopholes in the management structures, which allow corruption, theft, and mere selfishness to thrive. In addition to the negative impacts of these factors on implementation activities, there is also a general lack of institutional support for initiatives that could otherwise be very progressive. Thus, taken together, these retrogressive practices stifle African energy development plans. The book offers a valuable guide for developers, investors, researchers and environmentalist, providing in-depth insights on the relationship between available energy resources and development trends in Africa.

This book explores current developments in the African energy sector and highlights how these are likely to be affected by the ongoing global efforts to transition to a low-carbon economy. It analyses the legal, regulatory and policy frameworks at the national and regional level as they relate to Energy transition in Africa and discusses how regionalism is increasingly utilized to tackle energy access and climate change challenges. Using case studies from across the continent, several key thematic issues, including gender justice, social license to operate, local content and conflict of energy laws are covered in detail. The authors also uniquely examine the progressive nature of global energy use and introduce the new concept of ‘Energy Progression.’ This book will be an invaluable reference for researchers and policymakers looking for a comprehensive overview of the field.

The 1st World Conference and Technology Exhibition on Biomass for Energy and Industry, held in Sevilla in June 2000, brought together for the first time the traditional European Conference on Biomass for Energy and Industry and the Biomass Conference of the Americas, thus creating the largest and most outstanding event in the worldwide biomass sector. The conference elaborated innovative global strategies, projects and efficient practice rules for energy and the environment at a key stage in the industry's development. New concepts and projects were highlighted to increase the social and political awareness for a change in worldwide resource consumption and to promote economically, socially and environmentally sustainable development for the next millennium. In 2 volumes, the Proceedings include some 470 papers essential to an understanding of current thinking, practice, research and global developments in the biomass sector - a vital reference source for researchers, manufacturers, and policy makers involved or interested in the use of biomass for energy and industry.

Environmental problems are forcing a rethinking of the world’s energy supply system. In parallel, there is an increasing amount of global solid waste production. A fundamental shift toward greater reliance on biomass wastes in the world’s energy system is plausible because of ongoing major technological advances that hold the promise of making the conversion of biomass into high-quality energy carriers, like electricity and gaseous or liquid fuels, economically competitive with fossil fuels. Therefore, waste-to-energy systems have become a paramount topic for both industry and researchers due to interest in energy production from waste and improved chemical and thermal efficiencies with more cost-effective designs. This biomass shift is also important for industries to become more efficient by using their own wastes to produce their own energy in the light of the circular economy concept. This book on “Biomass Wastes for Energy Production” brings novel advances on waste-to-energy technologies, life cycle assessment, and computational models, and contributes to promoting rethinking of the world’s energy supply systems.
