This study investigated the factors influencing the adoption of urban agriculture (UA) as climate-smart agriculture (CSA) practices and its impact on food security in Wolaita Sodo City, South Ethiopia. Data from 384 randomly selected urban households showed that 53.53% adopted UA, with significant differences between adopters and non-adopters in employment, UA attitudes, and household size. A logistic regression model identified family size, home ownership, household head's occupation, UA perceptions, market demand, and access to training as determinants of adoption. Propensity score matching confirmed that UA adoption significantly improved food security by 0.685-fold.

This study investigated the impact of community green spaces on social cohesion and public health in Tudun Wada and Vanderpuye areas of Jos metropolis, Nigeria, during the COVID-19 pandemic. A survey of 400 participants using structured questionnaires and quantitative analysis found that community green spaces significantly enhance social cohesion and positively influence public health by reducing stress and promoting physical activity. The null hypotheses of no significant impact were rejected.

Mekonen Getachew Abebe · Journal of Agriculture and Food Research · Ethiopia

This review examined empirical evidence on the impacts of urbanization on food security in Ethiopia. The review showed that urbanization compromises all dimensions of food security through reductions in arable land and its productivity, waste dumping, biodiversity depletion, and water and soil pollution. Rapid urbanization leads to reduced production and higher food prices, resulting in a very high prevalence of food insecurity in Ethiopian urban areas. The review noted that Ethiopia has not implemented solutions like urban agriculture to its full potential.

This systematic review, conducted at Debre Berhan University, Ethiopia, assessed the role of horticulture in adopting climate-smart agriculture (CSA). Ethiopia's agriculture, which is the backbone of its economy, is adversely affected by climate variability and extreme events. CSA is presented as a primary solution to sustainably increase productivity, enhance resilience, reduce greenhouse gas emissions, and achieve food security. The principles of horticulture, including urban and peri-urban agriculture, silviculture, and agroforestry, are highlighted as having a strong capacity to adopt CSA.

This review paper examines existing literature on the effects of urban agriculture on the socio-economic status of urban farmers in Sub-Saharan African cities, specifically focusing on Zambia, South Africa, and Nigeria. The review found scanty information regarding how urban agriculture affects farmers' socio-economic status, how farmers derive social and economic status from it, and the types and motivations of farmers. It concludes that understanding crucial factors for food security, income, and related benefits in urban agriculture is essential for policy and technology development.

In Bokoni, northeastern South Africa, stone-walled towns flourished from the late 15th to early 19th centuries, and lidar data confirmed the presence of terraced fields in Khutwaneng from the 17th to early 19th centuries. All homesteads in this town had adjacent terraced gardens or fields, suggesting that urban farming was an entrenched component of Bokoni's urban life. Historically, women performed daily farming duties in southern Africa, and this was likely also the case in Bokoni.

This study investigated the impact of e-waste dumping sites on neonatal and infant mortality, focusing on two major dumpsites in Ghana and Nigeria. Using a difference-in-differences approach, outcomes were compared for children born near and far from dumpsites before and after their creation. E-waste sites increased neonatal and and infant mortality for those living closer to the sites, with event studies suggesting effects emerge two to three years after site openings. There is suggestive evidence that contamination of water and of urban farming produce are among the drivers of the observed effects.

A study in Hadnet district, Mekelle, Ethiopia, assessed heavy metal concentrations in wastewater, spring water, and three leafy vegetables (lettuce, spinach, cauliflower). Wastewater samples from four experimental sites exceeded permissible limits for 4 out of 10 heavy metals (Cd, Cr, Cu, Mn), and spring water from a comparison site also exceeded limits for 4 metals (Al, As, Cd, Cu). Leafy vegetables grown in the least contaminated experimental site showed high concentrations for 6-7 out of 10 heavy metals, with lettuce and spinach having elevated levels of As and Al, respectively. The study concluded that the wastewater used for irrigation is not safe, the farm soils may have accumulated significant heavy metals, and the cultivated vegetables are highly contaminated, necessitating regulation of wastewater use for irrigation.

A study was conducted in Eastern Ethiopia using primary data from 270 randomly selected urban farmers to identify factors influencing urban agriculture (UA) market participation decisions and intensity. The first stage of the Double Hurdle (DH) Model indicated that age, education, occupation, family size, farming experience, UA-related training, dependency ratio, and market information significantly impacted the decision to participate in the UA output market. The second stage DH Model showed that education, land size, UA-related training, and market information significantly affected the intensity of UA output market participation.

This exploratory qualitative research, conducted in Lagos, Nigeria, used focus group discussions to compare the perspectives of private urban farmers and public sector representatives on innovative urban farming. Urban farmers identified a lack of public sector support for circular agri-food technologies, while public sector representatives attributed issues to farmers' behavioral and educational shortcomings, including poor coordination. These differing views highlight complex dynamics and a need for structural changes and stakeholder dialogues to develop effective urban farming policies in Sub-Saharan Africa.

To evaluate the water quality of the Obibia River in Amawbia, Anambra State, Nigeria, water samples were collected monthly and assessed for bacteriological and physicochemical parameters. The study identified multiple bacterial isolates, including Escherichia coli, Klebsiella pneumoniae, Salmonella enterica serovar Typhi, and Vibrio cholerae. Notably, E. coli, S. Typhi, and V. cholerae were frequently observed in both rainy and dry seasons. These findings suggest the necessity of adequate treatment before use and periodic evaluation of the water's quality for drinking and urban agricultural purposes.
