Implementing a Rainwater Sustainable Control in Sahel-Feedback from "Niayes" Zone of Dakar
2012Sylvestre Dasylva · Journal of environmental science & engineering · Senegal (Dakar)
This paper discusses rainwater management in the "niayes" zone of Dakar, Senegal. This area is characterized by agricultural depressions with typically high groundwater levels, but a recent drop has turned some into runoff-gathering sites, used for urban agriculture among other services. However, two acute problems are observed: hydrological drying due to insufficient rainwater refill and urbanization of these bottom-lands. Furthermore, decreasing pluviometry exacerbates nuisances like floods and malaria.

2012Danny Simatele, Tony Binns, Munacinga Simatele · Journal of Human Development and Capabilities · Zambia (Lusaka)
This field-based research in Lusaka, Zambia, examines the impact of climate change and urban governance on urban agriculture, which serves as a source of food and income for poor households amidst deteriorating economies. The study finds that urban agriculture is often excluded from urban development and planning policy, posing significant challenges for small-scale farmers to achieve food security. A lack of policies supporting the urban poor, combined with climatic changes like drought and flooding, makes it difficult for households to adapt to the changing urban environment.

2012Silvio Caputo · Kent Academic Repository (University of Kent) · United Kingdom
This paper argues for a new role for urban agriculture in developed countries, focusing on environmental, social, and economic benefits. While urban agriculture can contribute to a low-carbon society and food access, it is not currently part of UK government strategies for food security. For urban agriculture to achieve its potential, it needs to become economically viable, requiring research into highly productive methods and business models utilizing local urban resources.

2010Eva Collins, Kate Kearins · Academy of Management Learning and Education · New Zealand (Auckland)
A sustainability instructor took a graduate class to an eco-village near Auckland, New Zealand, where students observed off-grid homes and community gardens. While New Zealand students were inspired by the alternative lifestyle, two international students from China and Tajikistan expressed that this lifestyle was how they lived at home and they did not wish to live that way, preferring the New Zealand lifestyle. This indicates a limited appeal of the eco-village model to some international students.

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.

2008Tamara García–Armisen, Josué Prats, Yociel Marrero, Pierre Servais · Water Science & Technology · Cuba (Havana)
The Almendares River in Havana, Cuba, receives wastewater from over 200,000 inhabitants, resulting in very poor microbiological water quality downstream due to high faecal bacterial indicators (FBIs). This water is used for urban agriculture and recreation, despite not meeting microbiological standards. This study compared FBI removal in three wastewater treatment plants (WWTPs): a conventional facility, a constructed wetland (CW), and a solar aquatic system (SAS). Natural systems (CW and SAS) showed approximately two log units higher FBI removal efficiency than the conventional plant. The large conventional WWTP was found to have a negative impact on the river's microbiological quality.

2007Viola Devasirvatham, P. S. Cornish · International Journal of Water · Australia
Peri-urban horticulture in Australia requires irrigation for year-round vegetable production. Subsurface Drip Irrigation (SDI) offers higher water use efficiency and crop yields, with the potential to reduce environmental risks from drainage and runoff. However, SDI has potential disadvantages, including poor germination or crop establishment and uneven wetting patterns. Research is needed to solve these problems and enable environmentally acceptable vegetable production.
