Geospatial Dynamics of Urban Irrigation Agricultural Land Use for Sustainable Income Generation on the Jos Plateau
2026Dr. Emmanuel Omomoh, Sunday Nannim, Dr. Rogers Rengje. Danlami Gujahar, Moses Omitunde Omirinde, Gwamzhi Ponsah Emmanuel · International Journal of Latest Technology in Engineering Management & Applied Science · Nigeria (Jos)
A study analyzed urban irrigation agricultural land use changes in Jos South Metropolis, Nigeria, over a ten-year period (2014–2024) using geospatial techniques and fieldwork. Market garden area declined by 5.84%, while settlements expanded by 34.76%. Key constraints to sustainable urban agriculture were identified, including land tenure insecurity (63% of dry-season farmers were landless), limited access to irrigation water, pest and disease pressure, inadequate fertilizer supply, and increasing competition for land from urban development.

2024Jeffrey Chiwuikem Chiaka, Gengyuan Liu, Hui Li, Wen Zhang, Mingwan Wu, Zhaoman Huo, F. Gonella · Environmental and Sustainability Indicators · Sub-Saharan Africa
This study evaluated land cover change and its drivers using spatial and statistical analysis in 22 designated protected areas (PAs) across the tropical coastal regions of sub-Saharan Africa. Results indicated that food production is prevalent in these protected areas regardless of their designation, and forest loss occurred in most PAs, suggesting weak conservation. Population density was the most significant driver of land cover change, and only 15 out of 22 protected areas showed an increase in their total ecosystem service value.

2023Bismark Osei, Mark Edem Kunawotor, Paul Appiah-Konadu · International Journal of Social Economics · Africa
This study examined measures for achieving a sustainable environment to mitigate climate change in 54 African countries from 2000 to 2020, using panel data and a Cox proportional hazard model. Findings indicate that carbon farming, rooftop gardens, and renewable energy positively contribute to a sustainable environment. However, governance adversely affects the objective of achieving a sustainable environment.

2023Abrham Kassa Ejigu, Kumelachew Yeshitela · Frontiers in Sustainable Cities · Ethiopia (Arba Minch City)
A study assessed Arba Minch City's governance capacity to integrate resource-oriented sanitation technology with urban agriculture. The findings indicated that the city's capacity is hindered by a lack of systematic monitoring, fragmented policy tools, and inadequate public sector participation. There is no single government body responsible for integration, and a behavioral gap exists among users in adapting to new technologies and recovered organic fertilizer.

2023Cynthia Nneka Olumba, Eberechukwu Johnpaul Ihemezie, Chukwudi Charles Olumba · Climate and Development · Nigeria
This study aimed to understand urban farmers’ perceptions of climate change and the adaptation constraints they encounter in Anambra Metropolis, Nigeria. Household survey data using structured questionnaires showed that most urban farmers perceived climate change through effects such as increased weed infestation, drying up of streams/rivers, and decreased soil moisture. Principal adaptation constraints were diverse, falling within broader institutional, information, and financial categories. The study revealed that the socioeconomic conditions of urban farmers in developing countries pose a threat to urban agriculture's potential to mitigate climate change.

2022Bethuel Sibongiseni Ngcamu · Environmental & Socio-economic Studies · Africa
This literature review explored the effects of urbanization on food security in Africa by reviewing eleven empirical journal articles. Findings indicate that rapid, unplanned urbanization has led to increased food insecurity, environmental degradation, and unsustainable food security, exacerbated by ill-prepared and incompetent governments. Key issues identified include poor government interventions, inadequate land-use planning, and high incompetency among urban planners.

2022Axel Prestes Dürrnagel, Matias Siueia Júnior, Simone Prestes Dürrnagel · Boletim GeoÁfrica · Mozambique
In Maputo, Mozambique's capital, urban agriculture is at a critical point, with accelerated urban growth and climate change impacts increasingly compromising agricultural spaces. A qualitative case study focusing on farmer associations in the urban district of KaMavota indicated that horizontal relationships among farmers enable information sharing and social capital creation. Conversely, vertical relationships between farmers and the government primarily promote knowledge exchange and competencies related to agricultural extension and land rights allocation.

2019Nicolette Tamara Jonkman, Boris Jansen · Current Opinion in Environmental Sustainability · Sub-Saharan Africa
This literature review on urban agriculture (UA) in Sub-Saharan Africa (SSA) identifies a significant constraint: conflicting stakeholder perceptions of UA, which hinders its development into a sustainable business. Some view UA as illegal and unsustainable, while others see it as a means to food security and employment. The review highlights a knowledge gap regarding land-use history and its effect on UA soil composition and nutrient status, proposing that UA sustainability requires understanding this historical context to build inclusive business models.

1993Lee M · PubMed · Ethiopia
In Ethiopia, urban agriculture faces significant challenges due to government disapproval of public land use for farming and difficulty in obtaining credit. A 1983 survey in Addis Ababa found that 17% of 1352 households produced their own food on less than 25 sq. meters, with 90% of non-farmers citing lack of land. Despite urban agricultural cooperatives demonstrating 70% higher member income, their lack of government legalization prevents access to loans for productivity improvement.
