2014Nairobi Kenya · · Kenya (Nairobi)
This research investigated the type and distribution of urban and peri-urban agriculture production systems in Nairobi County, Kenya. Results showed that crop-only cultivation accounted for 58.8% in Kamukunji district, while mixed farming was predominantly practiced in Starehe district at 39.1%. Multi-storey (42.5%) and moist gardens (25%) were the most common urban production technologies, whereas drip irrigation (23.6%) and multi-storey gardens (25.5%) were preferred in peri-urban areas.
Peri-urban agricultureDIYHeavy metal content of selected African leafy vegetables planted in urban and peri-urban Nairobi, Kenya
2014A. N. Mutune, M. A. Makobe, Mary Abukutsa‐Onyango · African Journal of Environmental Science and Technology · Kenya (Nairobi)
This study analyzed heavy metal content in 10 common African leafy vegetables and their rhizosphere soils from 25 sites along Nairobi Rivers, Kenya. While soil metal concentrations were generally within WHO/FAO permissible levels, except for some cadmium instances, all metals except copper in vegetables exceeded recommended limits at a few sites. This indicates potential heavy metal absorption from industrial and domestic effluent.
Contamination & food safetyHealthPeri-urban agricultureOpportunities and Needs in Development and Adoption of Urban Agriculture for Food Security in Sub Saharan Africa
2014Never Assan, Edmore Nhamo · · Sub-Saharan Africa
This discussion highlights the opportunities and needs for developing and adopting urban agriculture to enhance food security in Sub-Saharan Africa. It notes that rapid urbanization is increasing demand for crop and livestock products, leading to a growing food deficit and affecting urban food insecurity. Strategies to promote food productivity gains should focus on infrastructure, appropriate agricultural policies, new technology, and incentives for urban farmers within a fair policy environment.

Climate changeCommunityWelfareEvaluation of Urban Forestry and Housing Patterns in Awka Metropolis of Anambra State, Nigeria
2014H. C. Agada, E. A. Obienusi, Emma E. Ezenwaji · Journal of environment and earth science · Nigeria
This study evaluated urban forestry and housing patterns in Awka metropolis, Anambra State, Nigeria, over a ten-year period (2001-2010). Analysis of land use data using linear regression and correlation coefficients confirmed a significant correlation between housing patterns (urbanization) and the distribution of trees (forestry). The least square regression results indicated that the rate of forest displacement is a direct consequence of increasing structural development in the study area.

2013Phil. Caleb Mireri · African Journal of Agricultural Research · Kenya (Kisumu)
This study surveyed 194 urban farmers in Kisumu municipality, Kenya, to assess urban agriculture's role in income, employment, and food supply. It found that most urban farmers and their employees receive very low income, with a mean monthly income of US$135 (US$0.64 per person per day), which is below the acceptable one dollar a day per person. Urban agriculture primarily supplements food requirements for the urban poor and provides income for a few commercial farmers.

2013Asadu A. N · DOAJ (DOAJ: Directory of Open Access Journals) · Nigeria (Imo State)
A study investigated gender roles in urban crop production in Imo State, Nigeria. Data were collected from 60 respondents via interview schedules, revealing that 60% of urban farmers were female with an average age of 40 years. Mixed cropping was the most common system, with cassava, maize, and Telfaria as major crops. Both men and women were involved in securing plots, and all family members participated in fertilization and harvesting. Weeding and processing were primarily done by women and girls, while men mostly handled chemical spraying.
CommunityEconomicsWelfarePollution as a threat factor to urban food security in metropolitan Kano, Nigeria
2013Mansur Usman Dawaki, Abubakar U. Dikko, S. S. Noma, Umar Aliyu · Food and Energy Security · Nigeria
This study evaluated pollution risks to food security from urban agriculture in Kano, Nigeria, by sampling soil, water, and lettuce from two wastewater-irrigated sites (Challawa, Jakara) and a control site (Watari). Results showed all sites were contaminated with Cu, and the domestic wastewater site was slightly polluted with Pb and excessively polluted with Cd and Cr. Metal levels in irrigation waters exceeded recommended thresholds, and plants at the domestic wastewater site accumulated metal concentrations (Pb=26.21 mg/kg, Cd=1.03 mg/kg, Cr=28.63 mg/kg, Cu=2.66 mg/kg) that exceeded allowable limits in vegetables, indicating a human ingestion risk.

In 2013, the effectiveness of an awareness campaign promoting water conservation behaviors was investigated among 150 urban female gardeners in Lagos, Nigeria. A mixed-methods approach, including pre- and post-intervention surveys, found a significant increase from 25% to 48% in the adoption of water-saving irrigation techniques after the campaign. While the campaign was effective in enhancing knowledge and behavior, further tailored interventions are recommended for sustained impact.
CommunityClimate changeFood educationIs urban/peri-urban agriculture (UPA) a viable livelihood strategy? Evidence from Ethiopia
2013Teferi Daba Lemma, M. S. A. Rao, M Prasada Rao · Zenith international journal of business economics and management research · Ethiopia
This study assessed the economic sustainability of urban agriculture in central Ethiopia, collecting primary data from 280 urban and peri-urban vegetable farmers. Findings indicated that urban agriculture is a viable livelihood strategy from a financial perspective. However, city administrations and policymakers pay little attention to supporting this sub-sector, suggesting that legal recognition and support would make it a more reliable strategy.

2013R. O. Yusuf · · Nigeria (Kaduna State)
In Zaria, Kaduna State, Nigeria, a study examined the contribution of urban farming activities utilizing water from excavation pits to farmers' income and food security, and the eco-supportive component of using these pits. Data were collected from 10 farmers between December 2011 and May 2012 through structured interviews and observation. Farmers cultivated various crops and obtained higher incomes from farming compared to their primary occupations. The utilization of excavation pits was found to be eco-supportive by regulating the microenvironment's water balance, serving as carbon sinks, and providing low-cost water extraction. However, observed constraints included insecure land tenure, disturbance from straying domestic animals, and theft of farm produce.

2013Mekonnen Getahun, Yihenew G. Selassie · Journal of Agricultural Science · Ethiopia
A study investigated the extent of contamination of soil, water, and vegetables from wastewater used for irrigation in urban agriculture in Bahir Dar and Kombolcha, Ethiopia. Soil, water, and vegetable samples were collected and analyzed. While heavy metal concentrations in soil were within permissible levels, wastewater samples showed high nitrate and phosphate levels, and boron concentrations in Borkena River and Lake Tana exceeded permissible limits for irrigation. Wastewater drained to Lake Tana exhibited high turbidity and very high BOD, and lettuce and Swiss chard accumulated higher levels of iron, manganese, and zinc.

2013CDR Aza-Gnandji, Yongxin Xu, Lincoln Raitt, Jonathan Levy · Water SA · South Africa (Cape Town)
This study explored the salinity of irrigation water from the Cape Flats aquifer in the Philippi farming area of Cape Town, South Africa, collecting water samples from boreholes and ponds in summer and winter. Concentrations of chloride, nitrate, potassium, and sodium exceeded target maximum limits set by DWAF and FAO guidelines. Groundwater and pond water were found to be brackish in most parts of the research area, with salinization primarily attributed to agricultural activities. The water is generally suitable for irrigation but requires caution for salt-sensitive vegetables.
