Affordable Housing in the United States
by Gregg Colburn Rebecca J WalterAffordable Housing in the United States addresses the issue of affordability of housing, or the lack thereof, going beyond conventional policy discussions to consider fundamental questions such as: What makes housing affordable and for whom is it affordable? What are the consequences of a lack of affordable housing? How is affordable housing created? And what steps can be taken to ensure all people have access to affordable housing?With the understanding that different households face different challenges, the book begins by breaking down the variables relevant to the study of affordable housing, including housing costs, household income, geographic location, and market forces, to help readers understand and quantify affordability at the individual and societal level. Part II examines the consequences of unaffordable housing, highlighting racial inequities in housing access and affordability, and multiple forms of housing precarity including eviction and homelessness. Part III explores the entities involved in providing affordable housing such as local and federal governments, regulatory agencies, non-profit organizations, and for-profit developers. In Part IV, case studies from US cities demonstrate the complex web of organizations, policies, and market conditions that influence housing affordability, revealing substantial regional variations in access and policy response. Part V proposes a future roadmap and outlines four potential states with radically different outcomes for the affordable housing system in the United States.An ideal book for graduate and undergraduate courses in economics, public policy, real estate finance and development, sociology, and urban planning, this title will also be of value to professionals and policymakers seeking to understand and improve housing affordability and access.

Afghanistan-Pakistan Shared Waters: State of the Basins
by Alias Wardak Arif Anwar Fazilda Nabeel Hassaan Furqan Inayatullah Jan Karthikeyan Matheswaran Marie-Charlotte Buisson Muhammad Shahid Iqbal Muhammad Tousif Bhatti Muhammad Zia Hashmi Mujib Ahmad Azizi Paul Pavelic Shakeel Hayat Taimoor AkhtarThere is currently no water cooperation between Afghanistan and Pakistan. Of the nine rivers that flow across the border, none possess a formal agreement or mechanism to manage shared water resources. Further, there is very little information available about the status of environment, hydrology and water resources management for these river basins that could be used as a starting point for dialogues on transboundary water coordination. This State of the Basins book co-develops an overview of the three most important river basins, in collaboration with international experts and water professionals from Afghanistan and Pakistan. It covers water resources, land resources, ecological health, environment, climate change, and the social and economic conditions for sustainable management of these precious resources. It will inform decision making within the two countries, and begin to establish benefits that can accrue from more active collaboration on these shared waters. This book: · Focuses on portions of the Indus shared by Afghanistan and Pakistan. · Features extensive engagement and co-development with Afghan and Pakistani professionals. · Is the first book on the shared waters in the Indus, developed in the context of regional realities associated with post-August 2021 Taliban takeover. The book is aimed at students and researchers in water rights and resources, and government decision makers, private sector investors, donors, intermediary organizations that work directly with farmers, researchers and students. It is a reference book for graduate students and researchers working on these basins, and on transboundary river basin management in Asia and beyond.
Aflatoxin and Food Safety
by Hamed K. AbbasAflatoxins are responsible for damaging up to 25% of the world's food crops, resulting in large economic losses in developed countries and human and animal disease in under-developed ones. In addition to aflatoxins, the presence of other mycotoxins, particularly fumonisins, brings additional concerns about the safety of food and field supplies. The
Aflatoxins in Food: A Recent Perspective
by Khalid Rehman Hakeem Carlos A. F. Oliveira Amir IsmailMycotoxins are the metabolites of fungus and are reported to contaminate nearly 25% of the food produced worldwide. The mycotoxins of most significance are the aflatoxins due to their severe health implications and their prevalence in food commodities on a larger scale. Aflatoxins are produced by certain species of fungi the most prominent among which are Aspergillus flavus, A. parasiticus and A. nominous. Food commodities of African and South Asian countries are especially reported to have aflatoxins well beyond the allowable limits but due to the global trade of food commodities developed countries are also prone towards the perils of aflatoxins. Moreover, climate changes may have a substantial impact on the distribution and global prevalence of aflatoxins in the near future.The International Agency for Research on Cancer (IARC) has classified the aflatoxins as group 1 category carcinogen. Aflatoxins are also reported as teratogenic, mutagenic, growth retardant, immunosuppressant and may also cause nervous system and reproductive system disorders. Preventive approaches involving good manufacturing from “farm to fork” are the major focus of the current food industry.The aim of our book is to provide readers with the most recent data and up-to-date studies from aflatoxins research, with specific focuses on (i) the impact of aflatoxins on human health, (ii) new approaches by the researchers from different parts of the world to degrade aflatoxins and (iii) potential preventive approaches that can significantly lessen the burden of aflatoxins in food products
AFM-Based Observation and Robotic Nano-manipulation
by Lianqing Liu Ning Xi Shuai Yuan Zhidong WangThis book highlights the latest advances in AFM nano-manipulation research in the field of nanotechnology. There are numerous uncertainties in the AFM nano-manipulation environment, such as thermal drift, tip broadening effect, tip positioning errors and manipulation instability. This book proposes a method for estimating tip morphology using a blind modeling algorithm, which is the basis of the analysis of the influence of thermal drift on AFM scanning images, and also explains how the scanning image of AFM is reconstructed with better accuracy. Further, the book describes how the tip positioning errors caused by thermal drift and system nonlinearity can be corrected using the proposed landmark observation method, and also explores the tip path planning method in a complex environment. Lastly, it presents an AFM-based nano-manipulation platform to illustrate the effectiveness of the proposed method using theoretical research, such as tip positioning and virtual nano-hand.

African Edible Insects As Alternative Source of Food, Oil, Protein and Bioactive Components
by Abdalbasit Adam MariodThe harvesting, processing and consumption of edible insects is one of the main keys to the sustainability of food chains on the African continent. Insects are the largest and most successful group of animals on the planet and it is estimated that they comprise 80% of all animals. This makes edible insects extremely important to the future survival of large populations across Africa and the world. Insects offer a complete animal protein that includes all 9 essential amino acids and are very competitive with other protein sources. They are also a good source of beneficial unsaturated fats, and many insects have a perfect Omega 3:6 balance. African Edible Insects As Alternative Source of Food, Oil, Protein and Bioactive Components comprehensively outlines the importance of edible insects as food and animal feed and the processing of insects in Africa. The text also highlights indigenous knowledge of edible insects and shows the composition and nutritional value of these insects, plus presents reviews of current research and developments in this rapidly expanding field. All of the main types of edible insects are covered, including their nutritional value, chemical makeup, and harvesting and processing details. The various preparation technologies are covered for each insect, as are their individual sensory qualities and safety aspects. A key aspect of this work is its focus on the role of insects in edible oils and gelatins. Individual chapters focus on entomophagy in Africa and the various key aspects of the continent's growing edible insect consumption market. As it becomes increasingly clear that the consumption of insects will play a major role in the sustainability of food chains in Africa, this work can be used as a comprehensive and up-to-date singular source for researchers looking for a complete overview on this crucial topic.

The African Food Crisis: Lessons from the Asian Green Revolution
by Goran Djurfeldt Magnus Jirstroml Rolf Larsson Hans HolmenThe goal of the research project resulting in this monograph was the systematic comparison between Asian agricultural development during the "Green Revolution" and the current agricultural situation in sub-Saharan Africa. The editors (from Sweden's U. of Lund and Link ping U.) include 14 papers that present and analyze macro- level data about national agricultural trends before, during, and after Structural Adjustment Programs and household-level survey data for comparison of countries. The analysis is geared towards investigating agro ecological, demographic, and technological obstacles to African agricultural development; the possible contributions of African smallholders to food security; the likely impact of market integration of small-scale integration on economic and ecological crisis; the inadequacy of export-oriented policies to meeting the demands of food security; and the relevance of the Asian model for Africa.

An African Green Revolution: Finding Ways to Boost Productivity on Small Farms (Natural Resource Management and Policy #48)
by Keijiro Otsuka Donald F. LarsonThis volume explores the usefulness of the Asian model of agricultural development for Africa, where, even before the recent world food crisis, half the population lived on less than on dollar a day, and a staggering one in three people and one third of all children were undernourished. Africa has abundant natural resources; agriculture provides most of its jobs, a third of national income and a larger portion of total export earnings. However the levels of land and labor productivity rank among the worst in the world. The book explains Africa's productivity gap and proposes ways to close it, by examining recent experience in Africa and by drawing on lessons from Asia.

Africa’s Green Revolution: Critical Perspectives on New Agricultural Technologies and Systems
by William G. Moseley, Matthew A. Schnurr and Rachel Bezner KerrThis volume examines the dominant neoliberal agenda for agricultural development and hunger alleviation in Africa. The text reviews the history of African agricultural and food security policy in the post-colonial period, across a range of geographical contexts, in order to contextualise the productionist approach embedded in the much heralded New Green Revolution for Africa. This strategy, supported by a range of international agencies, promotes the use of hybrid seeds, fertilisers, and pesticides to boost crop production. This approach is underpinned by a new and unprecedented level of public–private partnerships as donors actively work to promote the private sector and build links between African farmers, input suppliers, agro-dealers, agro-processors, and retailers. On the consumer end, increased supermarket penetration into poorer neighbourhoods is proffered as a solution to urban food insecurity. The chapters in this volume complicate understandings of this new approach and raise serious questions about its effectiveness as a strategy for increasing food production and alleviating poverty across the continent.This book is based on a special issue of African Geographical Review.
Africa's Mineral Fortune: The Science and Politics of Mining and Sustainable Development (Routledge Studies of the Extractive Industries and Sustainable Development)
by Saleem H. Ali Kathryn Sturman Nina CollinsFor too long Africa's mineral fortune has been lamented as a resource curse that has led to conflict rather than development for much of the continent. Yet times are changing and the opportunities to bring technical expertise on modern mining alongside appropriate governance mechanisms for social development are becoming more accessible in Africa. This book synthesizes perspectives from multiple disciplines to address Africa’s development goals in relation to its mineral resources. The authors cover ways of addressing a range of policy challenges, environmental concerns, and public health impacts and also consider the role of globalization within the extractive industries. Academic research is coupled with key field vignettes from practitioners exemplifying case studies throughout. The book summarizes the challenges of natural resource governance, suggesting ways in which mining can be more effectively managed in Africa. By providing an analytical framework it highlights the essential intersection between natural and social sciences, central to efficient and effective harnessing of the potential for minerals and mining to be a contributor to positive development in Africa. It will be of interest to policy makers, industry professionals, and researchers in the extractive industries, as well as to the broader development community.
Africa's Power Infrastructure
by Anton Eberhard Orvika Rosnes Maria Shkaratan Haakon VennemoAfrica's chronic power problems have escalated in recent years into a crisis affecting 30 countries, taking a heavy toll on economic growth and productivity. The region has inadequate generation capacity, limited electrification, low power consumption, unreliable services, and high costs. It also faces a power sector financing gap on the order of $21 billion a year. It spends only about a quarter of what it needs to spend on power, much of this on operating expenditure required to run the continent's high-cost power systems, leaving little for the huge investments needed to provide a long-term solution. Further development of regional power trade would allow Africa to harness larger scale more cost-effective energy sources, reducing energy system costs by $2 billion a year and saving 70 million tons of carbon emissions annually. Economic returns to investments in cross-border transmission are particularly high. But reaping the promise of regional trade depends on a handful of major exporting countries raising the large volumes of finance needed to develop generation capacity for export. It would also require political will in a large number of importing countries that could potentially meet more than half their power demand through trade. Power sector inefficiencies are high, deterring investment in new capacity and electrification. There are three types of sector inefficiencies. First, there are utility inefficiencies, which include system losses, under-collection of revenue and over-manning. These result in a major waste of resources adding up to $4.40 billion a year. Under-collection is the largest component of utility inefficiencies amounting to $1.73 billion, following by system losses at $1.48 billion and by over-manning at $1.15 billion. The second type of sector inefficiency is under-pricing of power. By setting tariffs below the levels needed to cover the actual costs, SSA countries forego revenues of $3.62 billion a year. The third type of inefficiency is poor budget execution. Only 66% of the capital budgets allocated to power are actually spent, with about $258 million in public investment earmarked for the power sector being diverted elsewhere in the budget. Full cost recovery tariffs would already be affordable in countries with efficient large scale hydro or coal-based systems, but not in those relying on small scale oil-based plants. Once regional power trade comes into play, generation costs will fall, and full cost recovery tariffs could be affordable in much of Africa. One of the key policy challenges is to strengthen sector planning capabilities, too often overlooked in today's hybrid markets. A serious recommitment to reforming state-owned enterprises should emphasize improvements in corporate governance more than purely technical fixes. Improving cost recovery is essential for sustaining investments in electrification and regional power generation projects. Closing the huge financing gap will require improving the creditworthiness of utilities and sustaining the recent upswing in external finance to the sector This book is based on extensive data collection undertaken between 2006 and 2008 by the Africa Country Infrastructure Country Diagnostic, an initiative of the Infrastructure Consortium for Africa delegated to the World Bank under the guidance of the African Union, African Development Bank and other multi-lateral and bilateral development institutions.

Africa's Water and Sanitation Infrastructure
by Sudeshna Ghosh Banerjee Elvira MorellaThe welfare implications of safe water and sanitation cannot be overstated. The economic gains from provision of improved services to millions of unserved Africans in enormous. The international adoption of Millennium Development Goals brought the inadequacies of service provision sharply into focus. With only 58% and 31% enjoying access to water and sanitation services respectively, Sub-Saharan Africa is the only continent that is off-track in achieving the MDGs in 2015. The problem is compounded by the fact that a rigorous and credible baseline did not exist on coverage to improved water and sanitation and resources required to meet the MDGs. This book aims to contribute to this gap by collecting a wealth of primary and secondary information to present the most up-to-date and comprehensive quantitative snapshot of water and sanitation sectors. The book evaluates the challenges to the water and sanitation sectors within the urban and rural areas and deepen our understanding of drivers of coverage expansion in the context of financing, institutional reforms, and efficiency improvements. Finally, the book establishes the investment needs for water and sanitation with a target of meeting the MDGs and compares with the existing financing envelopes, disaggregated by proportions that can be recouped by efficiency gains and net financing gaps. The directions for the future draw on lessons learned from best practices and present the menu of choices available to African countries. There is no recipe book that neatly lays out the possible steps the country should adopt to enhance coverage and quality of service. The challenges differ to a significant extent among African countries and solutions must be tailored to individual national or regional conditions.
Afrofuturism and Digital Humanities: Show Me and I Will Engage Differently
by Bryan W. CarterThis book brings Afrofuturism into conversation with digital humanities to pioneer the field of Digital Africana Studies, and shows how students and academics can engage with the vision of Afrofuturism, both theoretically and practically, in the classroom and through research. As Black people across the globe consider their place in the future following the past two decades of technological advancement, Afrofuturism and its relevance for the humanities has become ever pertinent. While Afrofuturism has thus far been discussed through a literary, artistic, or popular culture lens, growing use of new technologies, and its resultant intersections with the reality of our racial experiences, has created a need for approaching Afrofuturism from a digital studies perspective. Via detailed case studies, Bryan W. Carter introduces the field of Digital Africana Studies to demonstrate how this new area can be experienced pedagogically. Alongside the book, readers can also visit select Digital Africana Studies projects that exemplify the various technologies and projects described at the author’s website: ibryancarter.com/projects. Given its unique approach to the path-breaking tradition of Afrofuturism, the book will be indispensable for scholars and students across fields such as digital humanities, media studies, black studies, African American studies, and Africana studies.
After Access: Inclusion, Development, and a More Mobile Internet (The Information Society Series)
by Jonathan DonnerAn expert considers the effects of a more mobile Internet on socioeconomic development and digital inclusion, examining both potentialities and constraints.Almost anyone with a $40 mobile phone and a nearby cell tower can get online with an ease unimaginable just twenty years ago. An optimistic narrative has proclaimed the mobile phone as the device that will finally close the digital divide. Yet access and effective use are not the same thing, and the digital world does not run on mobile handsets alone. In After Access, Jonathan Donner examines the implications of the shift to a more mobile, more available Internet for the global South, particularly as it relates to efforts to promote socioeconomic development and broad-based inclusion in the global information society.Drawing on his own research in South Africa and India, as well as the burgeoning literature from the ICT4D (Internet and Communication Technologies for Development) and mobile communication communities, Donner introduces the “After Access Lens,” a conceptual framework for understanding effective use of the Internet by those whose “digital repertoires” contain exclusively mobile devices. Donner argues that both the potentialities and constraints of the shift to a more mobile Internet are important considerations for scholars and practitioners interested in Internet use in the global South.
