Cities, Poverty and Food: The role of municipalities in enhancing food security

Food security is an critical issue in most African cities. Local government initiatives such as the City of Johannesburg Food Resilience Strategy are established to enhance food security in the city. The article draws insight from literature across multiple disciplines to examine the extent to which the Food Resilience Strategy relates food security to the economic challenges which citizens face. It discusses critical themes for sustainable urban food security namely, skills capacity and knowledge transference, access to land and water, institutional challenges, economic factors, urban agriculture production and environmental factors. Finally, the article recommends an integration of diverse stakeholders in the design and implementation of the Food Resilience Strategy, and thereby foster synergies between local producers and the local food market.

Food Security in Ghanaian Urban Cities: A Scoping Review of the Literature

Urbanisation in Ghana could be negatively impacting the state of food security, especially in economically vulnerable groups. Food supply, safety, and quality are all aspects of food security which could be impacted. We conducted a scoping literature review to understand the nature and magnitude of evidence available on the urban food security situation in Ghana. A literature search was conducted in Medline, CINAHL, Embase, Global Health, Scopus, Web of Science, Africa Wide Information and Google Scholar to identify relevant peer-reviewed and grey literature. 45 studies, mainly cross-sectional surveys/food samples analysis, met the inclusion criteria. The majority of studies were concentrated in the Greater Accra Region (n = 24). Most studies focused on food safety and quality (n = 31). Studies on supply and stability were, however, scarce. Qualitative research methods were uncommon in the included studies. The existing literature on food security are concentrated in two regions: The Greater Accra and Ashanti regions. Future studies exploring food security in urban Ghana should focus on exploring the lived experiences and perceptions of food insecurity and food stability by urban-dwellers using qualitative methods. The evidence suggesting that the safety/quality of foods sold in Ghanaian markets is poor should be a concern to consumers and policy makers.

Urban Food Security of the Colombo Metropolitan Region (CMR) in Covid times

Colombo Municipality Region (CMR) consists of a highly complex food system that relies on the supply from distant outstations which literally collapsed during the pandemic situation. A requirement exists for empirical research to derive guidelines and recommendations to increase the sustainability and security in the food supply in CMR during a disaster situation.

Prospects for Rooftop Farming System Dynamics: An Action to Stimulate Water-Energy-Food Nexus Synergies toward Green Cities of Tomorrow

Rooftop farming is a practical solution of smart urban agriculture to furnish diverse socio-environmental benefits and short food supply chains, especially in densely populated cities. This study aims to raise urban food security with less use of public water and energy in food production, through utilizing green water and energy for sustainable management. A system dynamics (SD) model framed across the nexus of climate, water, energy and food (WEF) sectors is developed for a rooftop farm in Taipei City of Taiwan. The urban WEF Nexus is structured to address how local weather affects water and energy utilization to grow vegetables. The SD results showed that the annual yields of sweet potato leaves achieved 9.3 kg/m2, at the cost of 3.8 ton/m2 of harvested rainwater and 2.1 ton/m2 of tap water together with 2.1 kwh/m2 of solar photovoltaic power and 0.4 kwh/m2 of public electricity. This study not only demonstrates that green resources show great potential to make a significant reduction in consuming urban irrigation resources for rooftop farming, but contributes to urban planning through a sustainable in situ WEF Nexus mechanism at a city scale. The WEF Nexus can manifest the rooftop farming promotion as cogent development to facilitate urban sustainability.

“The street is ours”. A comparative analysis of street trading, Covid-19 and new street geographies in Harare, Zimbabwe and Kisumu, Kenya

This collaborative and comparative paper deals with the impact of Covid-19 on the use and governance of public space and street trade in particular in two major African cities. The importance of street trading for urban food security and urban-based livelihoods is beyond dispute. Trading on the streets does, however, not occur in neutral or abstract spaces, but rather in lived-in and contested spaces, governed by what is referred to as ‘street geographies’, evoking outbreaks of violence and repression. Vendors are subjected to the politics of municipalities and the state to modernize the socio-spatial ordering of the city and the urban food economy through restructuring, regulating, and restricting street vending. Street vendors are harassed, streets are swept clean, and hygiene standards imposed. We argue here that the everyday struggle for the street has intensified since and during the Covid-19 pandemic. Mobility and the use of urban space either being restricted by the city-state or being defended and opened up by street traders, is common to the situation in Harare and Kisumu. Covid-19, we pose, redefines, and creates ‘new’ street geographies. These geographies pivot on agency and creativity employed by street trade actors while navigating the lockdown measures imposed by state actors. Traders navigate the space or room for manoeuvre they create for themselves, but this space unfolds only temporarily, opens for a few only and closes for most of the street traders who become more uncertain and vulnerable than ever before, irrespective of whether they are licensed, paying rents for vending stalls to the city, or ‘illegally’ vending on the street.

Food for Thought: Addressing Urban Food Security Risks through Urban Agriculture

Food and nutrition security has been neglected in the planning field for reasons of a lack of connection between food and planning and the perception that agricultural activities have no place in the modernizing world. However, considering increasing climate change impacts and implications on industrialized agriculture, there is a clear need to establish shorter, more sustainable agricultural production practices and food supply chains. Urban agriculture is proposed as a potential method of intervention for planners to support sustainable food production and supply chains. The paper utilized a multiple-case study design to analyze four best practice examples of urban agriculture in the Global South to uncover its potential to address food security associated risks and contribute to sustainable development objectives. The results delivered evidence of the potential to harness the multifunctionality of urban agriculture to not only improve the food security of the most at-risk populations, but to also address other urban risks such as unemployment, community decline and food deserts. The recommendations for this paper relate to establishing a food security department, mapping and encouraging more sustainable food supply chains, creating land uses and zonings specific to urban agriculture and to utilize its multifunctionality to address other urban risks.

Extent of urban agriculture and food security: evidence from Ghana and India

PurposeThe study attempted to assess the food security status of urban agriculture households in Ghana and India. Also, the extent of urban agriculture participation and its effect on food security in Ghana and India were examined.Design/methodology/approachA total of 650 urban agriculture farmers were interviewed for this study in Ghana and India. Food security status of urban households was assessed by the use of the Household Food Insecurity Access Scale, whereas the determinants of the extent of urban agriculture and its effect on food security were analysed by the use of the heteroskedastic linear regression and the Seemingly Unrelated Regression models, respectively.FindingsFrom the study on average, households in Ghana were mildly food insecure, but that of India was moderately food insecure. The results further revealed that various demographic, economic, institutional and health and nutrition factors differently influenced urban food security and urban agriculture. Also, the extent of urban agriculture participation positively influenced food security.Originality/valueSeveral studies in Asia (India) and Africa (Ghana) on urban food security have been geographically limited to New Delhi, Mumbai and Greater Accra, with few studies in the Middle Belt of Ghana, and Bihar in India. Besides, there is a limited, rigorous, empirical study on the effect of the extent of UA on food security in Asia (India) and Africa (Ghana) individually and together. Moreover, we extend the frontiers of the methodological approach by applying the Seemingly Unrelated Regression (SUR) model to understand if the factors that affect food-security accessibility based on two food security accessibility tools are correlated.
