“…CATPCA was done using the 23 variables derived from the surveys (Table 1). A component is considered reliable, if it contains a minimum of four variables with component loading score [ 0.6, because a variable with the higher loading score on a given component is the most influential variable, and contributing most to the variation accounted for that component (Abdulkadir et al 2012;Dossa et al 2011). Using this criterion, two principal components with loading score [ 0.6 were found per city (Table 2).…”

Urban and peri-urban agriculture (UPA) is important for food security in fast growing cities of developing countries. UPA also may have an important role in nutrient re-cycling at the interface of rural and urban areas. However, little is known about this role and whether it is different for different UPA systems. Here, we report on diversity and nutrient balances of UPA systems in three main cities of Ethiopia. Data collected from 425 households (Addis Ababa: 175, Adama: 126 Jimma: 124) were subjected to categorical principal component analysis and cluster analysis to classify the households. Four farm types per city and overall six: commercial livestock (cLS), commercial vegetable crop (cVC), subsistence field crop (sFC), cLScVC, cLScVCsFC and sVCsFC were identified across the three cities. Two types, cLS and cLScVC were common to the three cities. The farm types differed in resource endowment, income, soil fertility management and nutrient balances. cLS systems accumulated 450, 85 and 260 kg N, P and K ha -1 year -1 and had 26% N and P and 15% K use efficiency, respectively while sFC systems depleted -30 kg N and -17 kg K ha -1 year -1 and had 155% N and [ 100% K use efficiency. There was little exchange of manure and crop residue between LS, FC and VC systems. To use the potential role of UPA in nutrient recycling, a directive that imposes LS systems to distribute their surplus manure resources to proximate FC and VC systems and improve their nutrient use efficiency should be put in place.

“…UPA households were selected through the snowball sampling technique (Dossa et al 2011). According to Israel (1992), a sample size of 200 is appropriate for farmers' population between 5000 and 10,000 at 95% confidence level and 7% precision level.…”

“…The loading score of each variable is presented in Table 2.2. The extracted component scores and variables with a score value > 0.6 in one of the two components were then used for two-step clustering (Dossa et al, 2011). Before running the cluster analysis, a visual binning procedure was performed to convert continuous variables into nominal variables and reduce the higher weight of categorical variables at the expense of continuous variables (Dossa et al, 2011).…”

Assessment of peri‐urban livestock producers’ willingness to pay for improved forages as cash crops

Availability of quality feed is a major constraint for livestock production in Burkina Faso. Despite previous efforts to test improved forages at research stations to overcome the dry‐season feed gap, little has been done to promote them as cash crops that can contribute to meeting the growing feed demand in the country. This study was undertaken to evaluate the willingness to pay (WTP) for improved forage by livestock producers in the peri‐urban livestock production systems of Burkina Faso. A total of 202 livestock producers were interviewed using semi‐structured questionnaires. The contingent valuation method and Tobit econometric model were used to analyze the survey data. Exactly 79% of the interviewed livestock producers were willing to pay for improved forages for their livestock. Key factors that significantly affect this decision were the price of cottonseed cakes used as supplemental feed (P = .001), farmers’ knowledge about improved forage crops (P = .001), farmers’ ethnicity (P = .05), and farmers’ practice of daily grazing and transhumance (P = .01). The estimated WTP for improved forage as a cash crop was US$0.32 kg–1 for all livestock producers and $0.58 kg–1 for those who only expressed a positive WTP. The positive WTP for improved forages and factors affecting that decision suggest that producing improved forages is a viable alternative to expensive cottonseed cakes and the practice of transhumance to overcome the dry‐season feed gap. Therefore, dissemination of improved forages is recommended to market‐oriented crop farmers to meet the growing feed demand in Burkina Faso.
