“…Multivariate techniques show relationships between different variables and thereby outperform single-criteria classifications. The farmer typology described in our study is similar to Veenhuizen and Danso (2007) and Abdulkadir et al (2012). Field crop and vegetable farmers are common urban and peri-urban agricultural systems in many developing countries (Drechsel et al, 2006;Pasquini et al, 2010;Abdulkadir et al, 2012).…”

“…Market-oriented and intensified vegetable production on small areas of public land has been reported in several countries (Drechsel et al, 2009;Pasquini et al, 2010;Abdulkadir et al, 2012). For example, West African urban farmers produce vegetables on land ranging from 0.07 to 0.41 ha (Abdulkadir et al, 2012); however, the vegetable production is more intensive than those identified in our study. Many field crop farmers used family labour for agricultural activities, while more than 76% of ornamental-plant and vegetable growers hired additional labour (i.e field crop farmers and unemployed urban dwellers).…”

“…Many field crop farmers used family labour for agricultural activities, while more than 76% of ornamental-plant and vegetable growers hired additional labour (i.e field crop farmers and unemployed urban dwellers). The family labour reported in this study was very low compared to urban and peri-urban farming systems in West African and Asian countries (De Bon, 2001;Abdulkadir et al, 2012). Hence, a shortage of labour could be another reason for less intensified production in our study.…”

“…CATPCA was performed using IBM SPSS Statistics 22.0 to identify relationships between variables and to reduce a large number of variables into a small number of orthogonal components.

Urban and peri-urban agriculture (UPA) is an important livelihood strategy for the urban poor in sub-Saharan Africa and contributes to meeting increasing food demands in the rapidly growing cities. Although in recent years many research activities have been geared towards enhancing the productivity of this land-use system, little is known about turnover processes and nutrient efficiency of UPA. The aim of our study therefore was to determine horizontal fluxes of N, P, K, and C as well as gaseous N and C emissions in urban vegetable gardens of Bobo-Dioulasso, Burkina Faso. Two gardens referred to as "Kodéni" and "Kuinima" were selected as representative for urban and peri-urban systems classified as: (1) "commercial gardening + field crops and livestock system" and (2) "commercial gardening and semicommercial field crop system", respectively. A nutrient-balance approach was used to monitor matter fluxes from March 2008 to March 2009 in both gardens. Ammonia (NH 3 ), nitrous oxide (N 2 O) and carbon dioxide (CO 2 ) emissions from the respective soils were measured during the coolest and the hottest period of the day using a closed-chamber system. Annual partial balances amounted to 2056 kg N ha -1 , 615 kg P ha -1 , 1864 kg K ha -1 , and 33 893 kg C ha -1 at Kodéni and to 1752 kg N ha -1 , 446 kg P ha -1 , 1643 kg K ha -1 , and 21 021 kg C ha -1 at Kuinima. Emission rates were highest during the hot midday hours with peaks after fertilizer applications when fluxes of up to 1140 g NH 3 -N ha -1 h -1 , 154 g N 2 O-N ha -1 h -1 , 12 993 g CO 2 -C ha -1 h -1 were recorded for Kodéni and Kuinima. Estimated annual gaseous N (NH 3 -N + N 2 O-N) and C (CO 2 -C + CH 4 -C) losses reached 419 kg N ha -1 and 35 862 kg C ha -1 at Kodéni and 347 kg N ha -1 and 22 364 kg C ha -1 at Kuinima. For both gardens, this represented 20% and 106% of the N and C surpluses, respectively. Emissions of NH 3 , largely emitted after surface application of manure and mineral fertilizers, accounted for 73% and 77% of total estimated N losses for Kodéni and Kuinima. To mitigate N losses nutrient-management practices in UPA vegetable production of Bobo-Dioulasso would greatly benefit from better synchronizing nutrient-input rates with crop demands.

Societal Impact StatementCultivation of strawberry plants in urban production systems, whether in green open‐air spaces or under some form of protected horticulture such as vertical farming, has demonstrated to be challenging to new farmers and businesses. Commercial strawberry producers have an advanced understanding of strawberry plant physiology, enabling them to grow the crop successfully and profitably. Lack of knowledge exchange between commercial growers and new urban farmers seems to result in the abandonment of strawberries as crop of choice in urban systems. This review will confront the specific plant science challenges urban growers need to address to incorporate this nutritional crop into their revolutionary urban growing systems, whilst achieving good quality produce with high yields.SummaryTo ensure a sustainable future of farming, urban horticulture (UH) will need to be a key part of our everyday life. There are increasing demands for higher productivity and more locally produced food, even close to densely populated urban areas, to address environmental pressures and accelerate the resilience of modern food systems. UH is a broad term and can include numerous cultivation methods; rooftop gardens, public spaces, vertical walls, indoor vertical farms, as well as an array of crops including, salads, soft fruits and trees. Crops such as strawberries are expected to soon make a significant contribution to UH. Urban strawberry production promises all‐year round fruit availability, reduced reliance on imports, increased self‐sufficiency, lower food miles, a supply of high‐quality fresh fruits from hyper‐local spaces, increased employment opportunities, welfare benefits and an opportunity to promote a sense of community. Strawberry is a complex perennial crop with agronomical challenges, which requires specialist knowledge that is not always available to new urban farmers. Achieving an urban version of a strawberry field will require knowledge exchange between the commercial rural strawberry producers and the newly entered urban growers. Plant physiology, management of plant pathogens, choice of propagation material, fertigation, pollination and environmental requirements are the most common challenges for urban strawberry production. This review aims to consolidate the common bottleneck challenges of UH for new urban strawberry facilities.
