Agriculture urbaine et valorisation des déchets au Bénin : une approche de développement durable
2010Hygin Faust Kakai, Alban Gilles Kakai, Armelle Grey Tohouegnon · VertigO · Benin (Cotonou)
This study in Benin examined urban agriculture and waste valorization in Cotonou, Abomey, and Abomey-Calavi. In Cotonou, overexploitation of sandy, organic-poor soil in market gardening led to soil impoverishment, forcing gardeners to use chemical fertilizers with negative environmental impacts. However, some market gardeners adopted compost use, transitioning to organized organic urban agriculture after a waste management project supported waste valorization. This dynamic was not observed in Abomey, where urban agriculture is practiced in family spaces and public areas, unlike Cotonou's developed sites. Abomey-Calavi, despite rapid demographic growth, was almost devoid of urban agriculture practices.

2009W. Van Averbeke · Water SA · South Africa (Pretoria)
This study in five informal settlements of Atteridgeville, Pretoria, South Africa, used a pilot study, household survey, and multiple case studies to assess urban farming's contribution to food security and household income. While over half of households participated in urban farming, its contribution to total household income and food security was generally modest. Main constraints included lack of space and limited access to irrigation water.

2009Remi Adeyemo, F. Kuhlmann · Tropicultura · Nigeria
This paper evaluates the efficiency of resource use in urban food crop production in five districts of two cities in southwestern Nigeria, based on an effective sample of 120 respondents. The analysis showed that urban food crop production is profitable, with an average revenue of N51,294 per hectare and a gross margin of N23,688. However, there was disequilibrium in resource use, with planting seeds and agrochemicals used efficiently, but land and labor used inefficiently, indicating that urban food crop production has not yet attained an optimum level of resource combination.

2009Anges Yadouléton, Alex Asidi, Rousseau F Djouaka, B. James, Christian Agossou, Martin Akogbéto · Malaria Journal · Benin
A study in urban areas of Benin investigated the impact of rapid vegetable farming development on the emergence of insecticide resistance in Anopheles gambiae populations, using sociological data, bioassay tests, and biochemical analysis. The expansion of urban agriculture led to improper insecticide use for vegetable pests, exerting strong selection pressure on mosquito larval populations. This resulted in the emergence of insecticide resistance in malaria vectors, with permethrin mortality rates of 76% in Parakou, 23.5% in Porto-Novo, and 17% in Cotonou.

2009Andreas Buerkert, Eva Schlecht, Martina Předotová, Rodrigue V.C. Diogo, Katja Kehlenbeck, Jens Gebauer · eScholarship (California Digital Library) · Sub-Saharan Africa
This study analyzed urban and peri-urban agriculture (UPA) systems in major Sub-Saharan African cities, measuring carbon, nitrogen, phosphorus, and potassium fluxes and conducting biodiversity studies. In Niamey, low-input gardens showed annual gaseous carbon emissions of 20-25 t ha-1, predominantly CO2, and high-input gardens irrigated with wastewater had annual CO2-C emissions of 27 t ha-1, with N2O as a major nitrogen loss contributor. Animal manure stored in the open was subject to large carbon and nitrogen losses, indicating environmental tradeoffs. However, UPA gardens in Niamey maintained a large variety of fruit and vegetable species, with richness increasing with garden and household size and commercialization.

2009Abegunde A. A, Emmanuel Olufemi Omisore, O. F. Oluodo, D O Olaleye · African Journal of Agricultural Research · Nigeria (Lagos)
A study in the Eti-Osa local government area of Lagos, Nigeria, investigated the socio-spatial effects of urban horticultural gardens. Of 75 identified gardens, 63 managers were interviewed, revealing that 79.4% of gardens were profit-oriented. Gardens had inadequate setbacks (mean 1.45 m) from roads, leading to off-street parking and traffic congestion. Only 20% of horticulturists aimed to improve urban aesthetics, indicating a need for urban planners to educate them to prioritize urban aesthetics over economic gain.
Environmental trade-offsEconomicsUrban–rural linkageOverview on urban and peri-urban agriculture: definition, impact on human health, constraints and policy issues
2008Erastus K. Kang’ethe, Delia Grace, Thomas F. Randolph · East African Medical Journal · East Africa
This study synthesizes current knowledge on urban agriculture (UA) in East Africa, focusing on its human health impact. It identifies UA as an important source of food security, but notes that many zoonotic and food-borne diseases are associated with it, with a lack of evidence on human health impact and management. Major constraints include illegality and limited access to inputs and markets, indicating a need for more research to understand both positive and negative health impacts.

2008Anselm A. Enete, Anthonia Ifeyinwa Achike · Outlook on Agriculture · Nigeria (Ohafia)
A study comparing rural and urban farmers in Ohafia, southeast Nigeria, found that while urban farmers used significantly more purchased inputs than rural farmers, their output was significantly lower. This was attributed to urban farmers being poor and undercapitalized, preventing them from using adequate purchased inputs to maintain soil nutrients. The findings suggest that for urban agriculture to address urban food insecurity, the urban poor require sufficient financial empowerment.

2008Dick Foeken · · Africa
This study analyzed the relationship between urban policy and the practice of urban agriculture by the poor, based on two studies in Nakuru Municipality, Kenya, and Morogoro and Mbeya Municipalities, Tanzania. The legal and policy setting in these towns was found to be confusing, and the poor generally do not benefit from policy measures, if policies exist at all.

2008I. Ogunlade, O. I. Oladele, A. A. Falaki · University of Dar es Salaam Library Journal · Nigeria
This study investigated the socio-economic characteristics, information needs, and seeking behavior of 100 urban farmers in Ilorin metropolis, Kwara State, Nigeria, using a structured questionnaire. It found that urban farming was a supplementary activity for highly literate individuals, with farms mainly within the city and more animal than crop production. The study suggested that urban farmers could achieve better results if technical and financial support were provided, and recommended official government recognition for urban farming.

2008Pay Drechsel, Olufunke Cofie, R. van Veenhuizen, Theophilus O. Larbi · Irrigation and Drainage · West Africa
Informal irrigation in urban and peri-urban agriculture (UPA) in West Africa offers benefits but is often hindered by water pollution, threatening public health. A multi-stakeholder process implemented since 2005 in six West African cities, including Accra, Ghana, aimed to integrate UPA into sustainable urban development. However, an internal lesson learned was that local partners may not prioritize every project, and capacity-building efforts might not provide expected incentives for commitment.

2007Alex Thornton, Etienne Nel · Africanus Journal of Development Studies · South Africa (Peddie)
This study investigated the significance of urban and peri-urban agriculture (UPA) as a livelihoods strategy in Peddie, Eastern Cape province, South Africa, based on a PhD study. The findings indicate that UPA is not as significant or widely practiced as often assumed, despite its potential to address food insecurity and generate income. Its development has been slowed by various structural historical and socioeconomic barriers, limiting its current impact.

2006Halidou Koanda · Infoscience (Ecole Polytechnique Fédérale de Lausanne) · Sub-Saharan Africa
In Sub-Saharan Africa, faecal sludge management practices are often financially unviable due to widespread lack of municipal involvement, paucity of legal provisions, and absence of stakeholder coordination. This leads to indiscriminate dumping of faecal sludge in urban areas or its untreated use in urban agriculture. These practices pose permanent and serious health risks and contaminate scarce ground and surface water. This research aims to develop an innovative strategic planning approach for sustainable urban faecal sludge management to minimize public health and environmental risks.

2005Oumar Cissé, Ndèye Fatou Diop Gueye, Moussa Sy · Environment and Urbanization · Africa
This paper reports on research and city consultations in seven West African cities, examining the institutional aspects and constraints of urban agriculture. Despite growing interest from public authorities, this has not led to effective consideration in institutional and legal provisions in most countries. Decentralization processes have also not resulted in city government commitment to support urban agriculture, and its legal status remains uncertain.
Governance failurePolicyCommunityAn Assessment Of Urban Agricultural Land Use Changes Using Geospatial Information System: A Case Study Of Jos-Bukuru
2005E. Omomoh, C. O. Adeofun · · Nigeria
This study assessed urban agricultural land use changes in Jos-Bukuru, Nigeria, between 1961 and 2002 using a geospatial information system. It found that agricultural land use substantially increased from 1961 to 1986. However, between 1986 and 2002, approximately 63% of agricultural land was lost, with about 68% of this loss attributed to urban development. The study concludes that while urban spatial expansion is increasing, agricultural land use is decreasing.

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.

2003Olufunke Cofie, R. van Veenhuizen, Pay Drechsel · · Sub-Saharan Africa
Urban and peri-urban agriculture (UPA) significantly contributes to food supply, employment, livelihoods, and poverty alleviation in many Sub-Saharan African cities, providing diverse foods including perishable items. However, UPA production often carries health risks from polluted urban water and faces challenges due to limited semi-official recognition and support from city authorities, sometimes conflicting with planners regarding land tenure and water use. More data is needed for appropriate recognition of this sector.

2003Tony Binns, Roy Maconachie, Adamu Idris Tanko · Land Degradation and Development · Nigeria (Kano)
This paper examines health and environmental concerns associated with urban and peri-urban agriculture (UPA) in Kano, Nigeria. Empirical evidence indicates that industrial and domestic toxins are reaching dangerously high levels, leading to significant pollution of soils and water channels. This raises serious questions about the sustainability of UPA and the long-term health implications of toxin exposure.
Contamination & food safetyHealthPeri-urban agriculturePolicyOpportunities for managing solid waste flows in the periurban interface of Bamako and Ouagadougou
2003Derek Eaton, Thea Hilhorst · Environment and Urbanization · Africa
A 2003 paper examined the links between urban solid waste management and peri-urban agriculture in Bamako and Ouagadougou. Farmers near both cities value urban waste as an organic matter source and are willing to pay for it, but uncertain land tenure provides little incentive for safe disposal of dangerous elements in solid waste. Current plans to eliminate this recycling practice and promote large-scale composting are noted to be too costly for farmers, creating an incentive for illicit waste acquisition.

2003Ogunyemi Awodoyin, Taliat Opadeji · Emirates Journal of Food and Agriculture · Nigeria (Ibadan)
A 2003 study in Ibadan, Nigeria, investigated heavy metal contamination of Amaranthus cruentus L. grown on domestic refuse landfill soils. Lead (Pb) and Cadmium (Cd) concentrations in soils from four landfill sites and a control site ranged from 110.5 to 678.5ppm for Pb and 2.01 to 3.20ppm for Cd. Metal accumulation in Amaranthus cruentus L. tissues was proportionate to soil Pb concentrations, while Cd levels in crop tissues exceeded soil levels. Crop growth and yield were significantly reduced due to Pb and Cd contamination, leading to the conclusion that Ibadan landfills are unsafe for Amaranthus cruentus cultivation, with heavy metal concentrations in the vegetable tissues much higher than FAO/WHO dietary allowances.
