This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the solar panel prices falling recently, photovoltaic pumping systems (PVPSs) have become an affordable and effective technology for off-grid smallholder farmers in developing markets like Sub-Saharan Africa. Yet the high upfront cost of PVPSs remains a financial burden for many low-income farming communities. Although numerous efforts have been made to further increase the affordability of PVPSs, there is still a lack of investigation into potential energetic cost savings by improving solar pump efficiency from an architectural design perspective. In this study, a technoeconomic framework was developed to quantify the energetic costs of different solar pump architectures. The energetic cost is defined as the total cost of the solar array, which enables a direct comparison between efficiency and capital cost. New efficiency prediction models were formulated for 4-inch borehole pump hydraulics and submersible motors based on surveyed manufacturer specifications. Two types of case studies on SSA farms were conducted as example analyses in applying the framework. The operating space level analysis provides a bird's-eye view of the energetic cost-savings over the operating space when comparing two solar pump architectures. The operating point level analysis demonstrates a similar energetic cost analysis to identify the most energetically cost-effective solar pump architectures for the operating conditions of a specific SSA farm. By adopting highly efficient BLDC motors in 4-inch solar-powered borehole pumps, energetic cost-savings were found and operating regions not currently served by high-efficiency solar pumps can now be reached. These results highlight economic incentives for manufacturers to provide high-efficiency solar pumps to more smallholder farmers in SSA while reducing the overall upfront cost of PVPSs.

Download or read book The Climate Crisis written by Vishwas Satgar and published by NYU Press. This book was released on 2018-02-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essays that address the question: how can people and class agency change this destructive course of history? Capitalism’s addiction to fossil fuels is heating our planet at a pace and scale never before experienced. Extreme weather patterns, rising sea levels and accelerating feedback loops are a commonplace feature of our lives. The number of environmental refugees is increasing and several island states and low-lying countries are becoming vulnerable. Corporate-induced climate change has set us on an ecocidal path of species extinction. Governments and their international platforms such as the Paris Climate Agreement deliver too little, too late. Most states, including South Africa, continue on their carbon-intensive energy paths, with devastating results. Political leaders across the world are failing to provide systemic solutions to the climate crisis. This is the context in which we must ask ourselves: how can people and class agency change this destructive course of history? Volume three in the Democratic Marxism series, The Climate Crisis investigates eco-socialist alternatives that are emerging. It presents the thinking of leading climate justice activists, campaigners and social movements advancing systemic alternatives and developing bottom-up, just transitions to sustain life. Through a combination of theoretical and empirical work, the authors collectively examine the challenges and opportunities inherent in the current moment. This volume builds on the class-struggle focus of Volume 2 by placing ecological issues at the centre of democratic Marxism. Most importantly, it explores ways to renew historical socialism with democratic, eco-socialist alternatives to meet current challenges in South Africa and the world.

Download or read book Narratives of Low Carbon Transitions written by Taylor & Francis Group and published by Routledge. This book was released on 2020-09-30 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Open Access version of this book, available at https: //doi.org/10.4324/9780429458781, has been made available under a Creative Commons Attribution-Non Commercial-No Derivatives 4.0 license." This book examines the uncertainties underlying various strategies for a low-carbon future. Most prominently, such strategies relate to transitions in the energy sector, on both the supply and the demand side. At the same time they interact with other sectors, such as industrial production, transport, and building, and ultimately require new behaviour patterns at household and individual levels. Currently, much research is available on the effectiveness of these strategies but, in order to successfully implement comprehensive transition pathways, it is crucial not only to understand the benefits but also the risks. Filling this gap, this volume provides an interdisciplinary, conceptual framework to assess risks and uncertainties associated with low-carbon policies and applies this consistently across 11 country cases from around the world, illustrating alternative transition pathways in various contexts. The cases are presented as narratives, drawing on stakeholder-driven research efforts. They showcase diverse empirical evidence reflecting the complex challenges to and potential negative consequences of such pathways. Together, they enable the reader to draw valuable lessons on the risks and uncertainties associated with choosing the envisaged transition pathways, as well as ways to manage the implementation of these pathways and ultimately enable sustainable and lasting social and environmental effects. This book will be of great interest to students, scholars, and practitioners of environmental and energy policy, low-carbon transitions, renewable energy technologies, climate change action, and sustainability in general.

Download or read book Microorganisms for Green Revolution written by Deepak G. Panpatte and published by Springer. This book was released on 2017-12-07 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses basic and applied aspects of two nexus points of microorganisms in agro-ecosystems, namely their functional role as bio-fertilizers and bio-pesticides. Readers will find detailed information on all of the aspects that are required to make a microbe “agriculturally beneficial.” A healthy, balanced soil ecosystem provides a habitat for crops to grow without the need for interventions such as agro-chemicals. No organism in an agro-ecosystem can flourish individually, which is why research on the interaction of microorganisms with higher forms of life has increasingly gained momentum in the last 10-15 years. In fact, most of plants’ life processes only become possible through interactions with microorganisms. Using these “little helpers” as a biological alternative to agro-chemicals is a highly contemporary field of research. The information presented here is based on the authors’ extensive experience in the subject area, gathered in the course of their careers in the field of agricultural microbiology. The book offers a valuable resource for all readers who are actively involved in research on agriculturally beneficial microorganisms. In addition, it will help prepare readers for the future challenges that climate change will pose for agriculture and will help to bridge the current gaps between different scientific communities.
