Knowledge and Perception on the Usage of Greywater for Backyard Cultivation of Native Herbs Among Residents of Ibadan North Local Government Area, Ibadan, Nigeria
2025Mumuni Adejumo · Journal of Health and Environmental Research · Nigeria (Ibadan)
This cross-sectional study surveyed 312 residents in Ibadan North Local Government Area, Nigeria, to document their knowledge and perception of using greywater for backyard cultivation of native herbs. The findings revealed that 70.7% of participants had poor knowledge about greywater and its use for cultivating local herbs, and 61% held a negative perception. Only 8% of participants reported having used greywater in their residence, with 70.8% of public servants specifically showing negative perceptions.
DIYHealthCommunityThe Impact of Agricultural Extension Agents on Urban Gardening Practices in Confined Spaces and Focusing on Vegetable Crop Cultivation in Growth Media in Delta State, Nigeria
2025M. Elusaiwe, K. Atusa, Kanya Hilary · Asian Journal of Agricultural and Horticultural Research · Nigeria
This study investigated the efficiency of agricultural extension agents in promoting urban gardening among 250 respondents in 10 urban areas across two local government areas in Delta State, Nigeria. Findings revealed that most urban farmers, predominantly female civil servants, married women, or widows, were not visited by extension agents, nor were they encouraged to use growth media or form agricultural societies.

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.

2023O.M. Seretse, Abhishek Agarwal, Ulaula Mmiletsi, Mbizo Mpho · Advances in Modern Agriculture · Sub-Saharan Africa
This study designed a cost-effective, two-row donkey-drawn maize planter for small-scale farms in Sub-Saharan Africa, particularly Botswana, where donkeys are a primary power source. The assembled planter weighs 48.93 kg, can be drawn by three donkeys, and has an estimated cost of 200 USD. The study notes limitations and calls for further research to assess performance under varying soil conditions, durability, and planting efficiency.

DIYEconomicsExploration of wheatgrass as functional food by using urban agriculture models for regulating growth & nutrients
2022Nilesh L. Patil, Anjali A. Kulkarni, Dinesh Amalnerkar, Swapnil C. Kamble · South African Journal of Botany · South Africa
This study assessed the growth and nutrient values of wheatgrass cultivated in soil, hydroponics, aeroponics, and paper-pulp based potting mix soil. Plantlets from potting mix soil showed the highest height (88.67 cm), weight (15.13 gm), and overall nutrient content. Cost analysis over six months revealed that potting mix soil systems were 17x and 23x cheaper than hydroponics and aeroponics, respectively, making them the most productive for long durations.

2022Tadesse Wudu, Adimasie Kassaw · International Journal of Horticulture and Food Science · Ethiopia
An observational study in Sirinka, Ethiopia, in October 2018, investigated grafting 30-day-old tomato seedlings onto 20-day-old potato seedlings to create "pomato" plants for urban agriculture. Successful graft unions were observed after two weeks, with plants producing both tomatoes (average 18 fruits, 954g per plant) and potato tubers (4-5 tubers, 219.27g per plant). The experiment confirmed the success of the graft, suggesting its potential for home gardeners.

DIYEconomicsProduction of Edibles and Use of Garden Waste in Domestic Gardens of a Middle-Class Suburb in Cape Town, South Africa
2021Anjali Mistry, Manfred Spocter · · South Africa (Cape Town)
A study in a middle-class suburb of Cape Town, South Africa, investigated edible cultivation and garden waste management in domestic gardens. While potential gardening space averaged two-thirds of residential plots, 129 respondents primarily cultivated lawns, not food, with minimal vegetable production. Residents often used private gardening services for waste disposal, and on-site garden waste disposal techniques need promotion.

2021Karen Botes, Christina Breed · Acta Structilia · South Africa
This article reviewed three edible living wall case studies in Gauteng, South Africa, focusing on system resilience, economic feasibility, and edible plant possibilities. Interviews were conducted with clients, contractors, and designers. Findings suggested indirect commercial value through customer experience and educational value, but indicated that economic feasibility and resilience need enhancement for improved urban food production.

DIYEconomicsAdaptation of Excavation Pits for Sustainable Urban Farming and Eco-Supportive Infrastructure in Kaduna State, Nigeria
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.

2005Yali E. Woyessa, Etheresia Pretorius, Pieter S. van Heerden, M. Hensley, L. van Rensburg · WIT transactions on ecology and the environment · South Africa
This field survey in the Modder River basin, South Africa, investigated the potential expansion and implications of a rainwater harvesting technique introduced to small-scale farmers. While a rapid spread within home yard sizes was expected, no significant spread to community gardens or beyond was anticipated in the short term. This limitation was attributed to socio-economic constraints, including poverty and a lack of appropriate tools and basic farming skills.

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.
