Analysis on Factors Affecting the Growth of Micro and Small Enterprises: The Case of Gulele Sub-City, Addis Ababa, Ethiopia
2023Mohammed Seid Ebrahim · Ethiopian Journal of Business and Social Science · Ethiopia (Addis Ababa)
This study examined factors affecting the growth of micro and small enterprises in Gulele Sub-city, Addis Ababa, Ethiopia, using survey data from 120 enterprise leaders/owners. Enterprises grew at a rate of 0.20, but growth trends varied across sectors including urban agriculture. The analysis found that age, gender, and work experience of leaders/owners, along with enterprise age, employee numbers, workplace suitability, marketing problems, and government policies, significantly influenced growth, indicating that cumbersome bureaucratic procedures contributed to undergrowth and stagnation.
Governance failureEconomicsUrban–rural linkageFruits of the city: The nature, nurture and future of urban foraging
2023Mallika Sardeshpande, Charlie M. Shackleton · People and Nature · South Africa
This study interviewed 80 urban foragers in four cities in South Africa's eastern coastal region to understand urban foraging in a developing nation context. Foragers began foraging in childhood, viewing it as a cultural and recreational activity, but formal green spaces were not used for foraging and were perceived as poorly provisioned in urban planning. This indicates a lack of governance in urban planning regarding foraging.

2023Gareth Haysom, Jane Battersby · Palgrave studies in agricultural economics and food policy · Africa
Based on findings from cities in five African countries, this study argues for a re-framing of urban food system resilience. It contends that the urban system, specifically infrastructure, shapes the functioning of the food system and consumers' ability to use it, and that the agency of urban food system users needs inclusion in understandings of, and efforts to increase, food systems resilience.

2022Emaediong Uko, Tony Binns, Etienne Nel · Agroecology and Sustainable Food Systems · Nigeria (Benin City)
This study investigated the significance of urban and peri-urban agriculture (UPA) in Benin City, Southern Nigeria. Field-based data, collected using qualitative research methods (observation, in-depth interviews, and questionnaire surveys), revealed that in the context of unpredictable and frequent economic shocks, households across all socio-economic levels significantly depend on food production activities. This dependence serves not only for immediate survival but also as a means of reducing household vulnerability and building resilience against future shocks.

2021Alexander Follmann, Maximilian Willkomm, Gilbert M. Nduru, George Owuor, Peter Dannenberg · Applied Geography · Kenya
This study analyzes the spatiotemporal dynamics of market-oriented urban and peri-urban agriculture (UPA) and farmers' responses to changing socio-spatial circumstances in Nyeri and Nakuru, Kenya. Findings indicate that the continued existence of market-oriented agriculture in these cities is linked to dynamic processes of commercialization, specialization, and intensification. The research concludes that market-oriented farmers are not inevitably displaced but can actively adapt to pressures and opportunities arising from rapid urban growth.

2021Michael Kwabena Osei, Mavis Akom, Joseph Adjebeng‐Danquah, Kenneth Fafa Egbadzor, Samuel Oppong Abebrese, Kwabena Asare Bediako, Richard Yaw Agyare · · Sub-Saharan Africa
This abstract discusses the decline in soil fertility and accelerated desertification in Sub-Saharan Africa, including Ghana, due to decades of cropping. It introduces cover crops as a method to manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity, and wildlife in agro-ecosystems. The abstract also notes the increasing proportion of Ghana's population living in urban communities and that vegetable cultivation is conventionally a trade for rural dwellers.

2021Adugnaw Maru Gezahegn, Fekadu Fufa, Esayas Alemayehu, Abebe Beyene · Journal of Chemistry · Ethiopia (Modjo city)
This study investigated the spatial distribution and speciation of chromium in water, soil, and edible plants in tannery-contaminated areas of Modjo city, Ethiopia. Total chromium in the Modjo River was 20.6 mg L−1 upstream, and soil Cr (III) and Cr (VI) concentrations were found to be higher than guideline values. Chromium concentrations in edible plants were also significantly higher than in control areas, with roots accumulating more chromium than leaves and fruits. It was concluded that water, soil, and edible plants in this area contain chromium concentrations higher than recommended for a healthy environment and human consumption.
Contamination & food safetyHealthUrban–rural linkageReflecting on the Potential and Limitations of Urban Agriculture as an Urban Greening Tool in South Africa
2020Elizelle Juaneé Cilliers, Louis Lategan, Sarel S. Cilliers, Karla Stander · Frontiers in Sustainable Cities · South Africa
This paper investigates urban agriculture (UA) in South Africa as a citizen-led urban greening strategy, reviewing case studies and the national policy framework. Key limitations include many UA initiatives not being self-sustaining or fully citizen-driven, a cultural stigma, limited national support due to the absence of a dedicated UA policy, and South African spatial planners' limited knowledge of UA. These issues hinder the broader implementation of UA.
