The urban population in Africa south of the Sahara (SSA) is expected to expand rapidly from 376 million people in 2015 to more than 1.25 billion people by 2050. Measuring and ensuring food security among urban households will become an increasingly pertinent task for development researchers and practitioners. In this paper we characterize food security among a sample of low- and middle-income residents of Accra, Ghana, using 2017 survey data. We find that households tend to purchase food from traditional markets, local stalls and kiosks, and street hawkers, and rarely from modern supermarkets. We characterize food security using three established metrics: the Household Food Insecurity Access Scale (HFIAS); the Household Food Insecurity Access Prevalence (HFIAP); and the Food Consumption Score (FCS). We then estimate the determinants of food security using general linear models. The food security metrics are not strongly correlated. For example, according to HFIAP, as many as 70 percent of households sampled are food insecure, but only 2 percent fall below acceptable thresholds measured by FCS. Model results show that household education, assets, and dwelling characteristics are significantly associated with food security according to HFIAS and HFIAP, but not with FCS. The poor correlation and weak model agreement between the dietary recall metric, FCS, and the experience-based metrics, HFIAS and HFIAP, call for closer attention to measurement of urban food security. Given Africa’s urban future, our findings highlight the need for an urban-oriented comprehensive approach to the food security of urban households.

Affecting more than 800 million people, food insecurity is a global problem that runs deeper than hunger and undernutrition. In addition to the obvious impact on physical well-being, food insecurity can result in risky coping strategies, increased expenditures on medical costs or transportation, and mental health issues. A review of the concepts an

This is an open access book. Held as part of the Universitas Gadjah Mada Annual Scientific Conferences (UASC 2022) series, the 3rd International Conference on Smart and Innovative Agriculture (ICoSIA 2022) provides an ideal academic platform for researchers to present the latest research findings and describe emerging technologies and directions in agriculture. This year, the conference will take the theme “Digital transformation, technology, and its solution for agriculture” with seven symposia: Agricultural Big Data Analysis symposium; Agricultural Geography symposium; Land and Environmental Management symposium; Precision Nutrition Technology symposium; Smart and Precision Farming symposium; Smart Genetics Resource Management and Utilization symposium; and Sustainable Food Production symposium.

Smallholder agriculture is the mainstay of Malawi’s economy. Its importance for livelihoods cannot be overstated. 94 percent of rural residents and 38 percent of urban residents engage in agriculture to some extent (Jones, Shrinivas, and Bezner-Kerr 2014), the vast majority as smallholder farmers with landholdings of less than one hectare. Smallholder crops are primarily maize—which accounted for nearly 80 percent of smallholder-cultivated land in 2011 —followed by cassava and other food crops (FAO 2008; IFAD 2011). These foods are grown for household consumption and for sale at local and regional markets. As such, the Malawian food supply, especially in rural areas where markets are thin with few buying or selling options, is shaped largely by trends in smallholder food-crop production

'This volume is a welcome and timely contribution to a topic of enduring importance. The global consequences of recent food price crises underscore the need to examine food security issues from diverse perspectives. This volume meets that need, featuring accessible yet cutting-edge analyses of food security by leading experts in fields as diverse as trade, nutrition, public health, production, political economy, and behavioral economics. It will be of interest to a wide range of scholars and practitioners.' --Steven Block, Tufts University, US. 'This excellent volume offers a compact but wide-ranging survey of recent research on important changes in global food markets. Its 20 chapters accurately capture important areas of scholarly agreement as well as on-going debates among economists studying agriculture and nutrition, with several provocative original contributions from other fields. The book draws particularly on the authors' long experience in Asia, offering widely-applicable insights for scholars and policy analysts seeking to understand the past, present and future of food around the world.' --William A. Masters, Tufts University, US. The global population is forecasted to reach 9.4 billion by 2050, with much of this increase concentrated in developing regions and cities. Ensuring adequate food and nourishment to this large population is a pressing economic, moral and even security challenge and requires research (and action) from a multi-disciplinary perspective. This book provides the first such integrated approach to tackling this problem by addressing the multiplicity of challenges posed by rising global population, diet diversification and urbanization in developing countries and climate change. It examines key topics such as: the impact of prosperity on food demand, the role of international trade in addressing food insecurity, the challenge posed by greenhouse gas emissions from agriculture and land degradation, the implication on labor markets of severe under-nutrition, viability of small scale farms, strategies to augment food availability. The Handbook on Food would be a welcome supplementary text for courses on development economics, particularly those concentrating on agricultural development, climate change and food availability, as well as nutrition.
