Giuliano Pancaldi sets us within the cosmopolitan cultures of Enlightenment Europe to tell the story of Alessandro Volta--the brilliant man whose name is forever attached to electromotive force. Providing fascinating details, many previously unknown, Pancaldi depicts Volta as an inventor who used his international network of acquaintances to further his quest to harness the power of electricity. This is the story of a man who sought recognition as a natural philosopher and ended up with an invention that would make an everyday marvel of electric lighting. Examining the social and scientific contexts in which Volta operated--as well as Europe's reception of his most famous invention--Volta also offers a sustained inquiry into long-term features of science and technology as they developed in the early age of electricity. Pancaldi considers the voltaic cell, or battery, as a case study of Enlightenment notions and their consequences, consequences that would include the emergence of the "scientist" at the expense of the "natural philosopher." Throughout, Pancaldi highlights the complex intellectual, technological, and social ferment that ultimately led to our industrial societies. In so doing, he suggests that today's supporters and critics of Enlightenment values underestimate the diversity and contingency inherent in science and technology--and may be at odds needlessly. Both an absorbing biography and a study of scientific and technological creativity, this book offers new insights into the legacies of the Enlightenment while telling the remarkable story of the now-ubiquitous battery.

Sub-Saharan Africa has an irrigation potential of about 42 million hectares of which only 17% is developed. Despite several investments in irrigation the growth is slow. This study aims at helping to achieve sustainable irrigation in sub-Saharan Africa, through gaining a better understanding of productive irrigation water use and effective manageme

The Volta River Basin (VRB) is an important transboundary basin in West Africa that covers approximately 410,000 square kilometres across six countries: Benin, Burkina Faso, Côte d’Ivoire, Ghana, Mali and Togo. Its natural resources sustain the livelihoods of its population and contribute to economic development. This book provides a comprehensive, interdisciplinary review and assessment of the issues and challenges faced. The authors provide a science-based assessment of current and future scenarios of water availability, the demands of key sectors, including agriculture and hydropower, and the environment under changing demographic, economic, social and climatic conditions. They also identify solutions and strategies that will allow available water resources to be sustainably used to improve agricultural productivity, food security and economic growth in the VRB. Overall, the work examines from a multidisciplinary and multi-stakeholder perspective the solutions and strategies to improve the use of water and other natural resources in the VRB to achieve enhanced food security, livelihoods and economic growth.

For agriculture there is a continuum of water storage options, ranging from groundwater aquifers, soil water, natural wetlands and small ponds and tanks to large reservoirs. In any situation each of these has its own niche in terms of technical feasibility, socioeconomic sustainability and impact on public health and the environment. Planning storage requires insight into impending needs and also a good understanding of what already exists and what was, and was not, successful, in the past. This report provides an inventory of existing and prospective water storage in the Ghanaian Volta and the Ethiopian Blue Nile basins. It provides as much quantitative data as possible, but highlights both the dearth of readily available information and the lack of integrated planning of storage in both basins. Recommendations are made for improved planning in the future.
