Analysis of markets for African leafy vegetables within Nairobi ant its environs and implications for on-farm conservation of biodiversity

African Leafy Vegetables (ALVs) are important sources of essential macro and micro-nutrients. In addition they offer a source of livelihood when marketed, and also contribute to crop biodiversity. Despite these positive aspects, only a few ALVs are grown, marketed and consumed in Kenya. This study analyses the ALV market in Nairobi and the neighbouring areas, highlighting the factors that enable or inhibit its development. Furthermore, the study determined different factors influencing inter- and intra-specific on-farm biodiversity, with a focus on the role of ALV market development

Potential impact of groundnut production technology on welfare of smallholder farmers in Ghana

Open Access Journal; Published online: 14 Jan 2022This study was conducted to assess the potential impact of applying a new groundnut planting density on welfare of smallholder farmers in northern Ghana. We used data from on-farm experiments, focus group discussions, and a household survey. We followed three steps in our analysis. First, we conducted cost-benefit analysis in which we showed the economic advantage of the new technology over the farmers’ practice. Second, we predicted adoption rates along timeline using the Adoption and Diffusion Outcome Prediction Tool (ADOPT). Third, using the results of the first and the second steps, we estimated the potential impact of the technology on poverty at household level using a combination of methods such as economic surplus model and econometric model. The cost-benefit analysis shows that increasing plant density increases farmers’ financial returns i.e., the benefit-cost-ratio increases from 1.05 under farmers’ practice to 1.87 under the best plant density option, which is 22 plants/sqm. The adoption prediction analysis shows that the maximum adoption rate for the best practice will be 62% which will take about nine years to reach. At the maximum adoption rate the incidence of extreme poverty will be reduced by about 3.6% if farmers have access to the international groundnut market and by about 2% if they do not have. The intervention will also reduce poverty gap and poverty severity. The results suggest that policy actions which can improve farmers’ access to the international market will enhance farmers’ welfare more than the situation in which farmers have access to domestic markets only. Furthermore, promoting a more integrated groundnut value-chain can broaden the demand base of the produce resulting in higher and sustainable impact of the technology on the welfare of groundnut producers and beyond

Nutritional status of children 0-59 months in selected intervention communities in northern Ghana from the Africa RISING project in 2012

Background Poor nutritional status during childhood and its long-term impact on economic growth and wellbeing is well known. This study assessed the nutritional status of children in selected communities in northern Ghana, to serve as baseline data for the Africa Research in Sustainable Intensification for the Next Generation (Africa RISING) project that sought to improve farm-household nutrition through agriculture. Methods A cross-sectional study was conducted among children 0–59 months in selected communities in the Northern (Tibali andCheyohi No. 2), Upper West (Goli and Zanko) and Upper East (Bonia and Sambulgu) regions of northern Ghana. A pre-tested, semi-structured questionnaire was used to obtain information on background characteristics of caregivers and children. Weight and height were measured for children following World Health Organization (WHO) procedures and transformed into z-scores using the WHO Anthro. Results All the caregivers (522) were females; majority (73.4 %) had no formal education, 82.7 % were married and 70.5 % engaged in farming. In all, 533 children were recruited: Northern region (38.6 %), Upper West (33.4 %) and Upper East (28.0 %). Majority (52.5 %) of the children were males. The mean age was 32 ± 19 months. Levels of stunting, underweight and wasting were 27.2, 17.6 and 8.2 % respectively. Stunting, underweight and wasting levels increased within the first two years of life. Overall, 33.8 % of the children in northern Ghana were malnourished; 20.2 % were from the Northern region, 7.0 and 6.8 % were from Upper East and Upper West respectively. Conclusion Different forms of malnutrition still exist as a public health problem in various communities in northern Ghana and need to be curtailed using effective agriculture-nutrition sensitive interventions

Does nitrogen matter for legumes? Starter nitrogen effects on biological and economic benefits of cowpea (Vigna unguiculata L.) in Guinea and Sudan Savanna of west Africa

Open Access JournalThe hypothesis that application of starter nitrogen (N) fertilizer to cowpea may increase grain and fodder yields and profitability was tested in the Guinea and Sudan savanna zones of northern Ghana. Two cowpea varieties (Apagbaala: grain-type and Padi-Tuya: dual purpose) and three N fertilizer rates (0-30-30, 15-30-30 and 30-30-30 N-P2O5-K2O kg/ha) were evaluated using a 2 × 3 factorial treatments arrangement in a randomized complete block design with three replicates. Grain and fodder yields, 100 seed weight (SW) and net return of Padi-Tuya increased significantly compared with Apagbaala in both zones. Application of starter N fertilizer increased grain yield, fodder yield, N use efficiency (NUE) and net return by more than 30% compared with the control in both zones. Padi-Tuya cowpea with 15 kg/ha N fertilizer was risk efficient at all risk aversion levels when only grain was considered, but Padi-Tuya with 30 kg/ha N fertilizer becomes the most risk efficient option when the value of fodder was included. The results suggest that small-scale farmers could apply starter N fertilizer at either 15 kg/ha N for grain only or 30 kg/ha N for both grain and fodder yields improvement of cowpea in West Africa and similar ecologies

How far are we from adhering to national asthma guidelines: The awareness factor

AbstractBackgroundThe Saudi national asthma protocol (SNAP) for asthma management was released in 1995 in an attempt to streamline asthma management practices in Saudi Arabia and improve the quality of care for asthma. Up to our knowledge, few studies assessed the adherence of Saudi physicians to the national asthma guidelines.ObjectivesThe objective of this present study was to assess the level of adherence of pediatricians and primary care physicians (PCPs) to the current SNAP recommendations and identify barriers to physician adherence.MethodologyThis is a cross-sectional study involving pediatricians and PCPs selected randomly from five major governmental hospitals in Riyadh, Saudi Arabia. Subjects were administered a self-administered questionnaire comprising 24 questions assessing their awareness of SNAP and their level of adherence to the recommendations.ResultsThe response rate was 38% (80/206). Out of most of the physicians who responded, 70% (56) were aware of SNAP, and only 78.2% (n=43) of them had modified their management of asthmatic patients according to the SNAP recommendations. The level of knowledge of the pharmacotherapy and diagnostic parts of the guidelines ranged between 41.5% and 90.7% in the pharmacotherapy part, and 53.7–59.6% in the diagnostic part. The most common barriers to adherence to SNAP were lack of awareness (25.2%), patient non- compliance (18.9%) and lack of resources (13.5%). There was no significant difference in awareness between pediatricians and PCPs (69.2%, 70.7% respectively).ConclusionThis study reveals a substantial gap between the actual care provided by pediatricians and PCPs to asthmatic patients and the recommendations formulated in the Saudi National Asthma Protocol (SNAP). Lack of awareness remains the most common barrier for adherence to the guidelines followed by patient non-compliance. To improve SNAP guideline adherence, tailored interventions that address barriers to adherence need to be implemented

The income and food security impacts of soil and water conservation technologies in Tanzania

Open Access JournalSoil and water conservation technologies are critical in reducing drought and soil erosion risks and increasing crop yields and incomes. Yet, there is limited empirical evidence on the extent and impacts of adopting soil and water conservation technologies in Tanzania. The study’s objective is to evaluate the adoption (as well as the duration of adoption) and the impacts of soil and water conservation technologies on income and food security in Tanzania. The study employs a control function approach and the instrumental variable quantile treatment effects model to survey data from 575 households to estimate the average and distributional impacts of adoption. The results show that the adoption and duration of adopting soil and water conservation technologies had significant and positive effects on the total value of crop production and household income. Moreover, we find that the adoption and its duration had a significant and positive impact on the food security indicator—household dietary diversity. The results from the instrumental variable quantile treatment effects model also show that the impacts of adopting soil and water conservation technologies on the outcome variables are positive and significant, although they vary significantly across the income and food security distributions. The results indicate that even though adoption benefits households in both the lower and upper quantiles of the income and food security distributions, the marginal impacts of adoption are generally more significant for the households in the upper quantiles. The paper concludes by discussing the policy options for increasing and sustaining the adoption and impacts of soil and water conservation technologies in Tanzania

Maize–legume strip cropping effect on productivity, income, and income risk of farmers in northern Ghana

Open Access Article; Published online: 22 Nov 2020Maize (Zea mays L.)–legume intercropping is common cropping system among smallholder farmers in West Africa. However, little is known about the income risk reduction associated with maize–legume strip cropping in West Africa. A 3‐yr study was conducted in Upper West and Northern regions of Ghana to determine the effect of maize–legume strip cropping on productivity, income, and income risk using a randomized complete block design with five replications in each region. Seven treatments were used: sole crops of maize (M) cowpea [Vigna unguiculata (L.) Walp.] (C) and groundnut (Arachis hypogaea L.) (G), a combination of two rows of M and two rows of legumes (L) (2M:2C and 2M:2G), and two rows of M and four rows of L (2M:4C and 2M:4G). Maize–legume strip cropping options (2M:2L and 2M:4L) on the average saved 90–100% of agricultural land, significantly increased income by about threefold, and reduced risk of operating at a financial loss by 75% compared with sole cropping. Smallholder farmers, especially sole legume cropping farmers in the Guinea savanna of northern Ghana and similar agro‐ecologies in West Africa, could adopt maize–legume strip cropping systems (2M:4L or 2M:2L) to mitigate production risk and increase financial return
