Knowledge, perception and utilization of biofortified cassava and orange-fleshed sweet potato (OFSP) in selected rural areas in Nigeria

Vitamin A deficiency is a major public health problem in Nigeria. Staple crops are targeted by biofortification efforts because they possess low micronutrient density and are consumed in large quantities by a large proportion of poor households. This study was designed to assess the knowledge, perception and utilization of biofortified cassava and orange-fleshed sweet potato in selected Local government Areas in Abia and Imo States. The study was descriptive and cross-sectional in design. A total of 710 respondents were selected using a multi-stage sampling technique. A structured interviewer-administered questionnaire was used to elicit the required information. Statistical analysis was performed using descriptive statistics (frequency, percentage, mean and standard deviation) and inferential (correlation) analysis. Socio-demographic data revealed a preponderance of females, married, well-educated and working-class respondents. Monthly income above ₦29,000 (US$ 70.54) and household size of 4-6 members were reported in 53.5% and 48.6% of the respondents. Study results further revealed that some (34.9%) of the respondents had good knowledge, while 46.1% and 19.0% had an average and poor knowledge of biofortified staples, respectively. Orange fleshed sweet potatoes and biofortified cassava were purchased at least once monthly by 73.7% of the respondents, however 16.5% and 27.5% of the respondents consumed these biofortified staples on a daily and weekly basis. Low positive perception towards the consumption (27.5%), benefits (39.6%) and barriers (16.9%) of utilizing studied biofortified staples was reported. A positive correlation was observed betweenrespondents’ knowledge of biofortified staples and their benefits perception (p = 0.003), purchase (p =0.001) and consumption (p= 0.001) frequency. Therefore, while a good number of the respondents were fairly knowledgeable about the studied biofortified staples, it significantly influenced the perception and utilization of these staples, despite being reportedly low. Therefore, increased sensitization, price subsidy and availability of these biofortified staples will help improve their acceptance and utilization among rural households

From curiosity to commodity: a review of the evolution of sachet drinking water in West Africa

The private sector continues to play an important role in filling local drinking water supply gaps across the Global South. In West Africa, a perfect storm of rapid population growth, infrastructure mismanagement, and globalization of consumer markets has resulted in the advent of an entire new industry around packaged water, primarily ‘sachet water’ sold in mechanically sealed plastic sleeves. Most local governments and international development agencies have historically perceived sachet water as a passing trend, but it has quickly become a primary drinking water source for the majority of households in many urban areas and continues to spread throughout the region and world. Sachet water is now an important component of regional water security, although with attendant issues related to governance, quality control, environmental pollution, and social justice. This paper reviews the seminal literature on sachet water in West Africa, with particular emphasis on Ghana and Nigeria, where most studies have focused. This review synthesizes governance issues, consumer and industry trends, and the latest on product quality in the literature from 2011 to 2016, with 2010 approximating an inflection point for the modernization of the industry. The ability of many West African nations to achieve universal access to safe drinking water may depend on their willingness to understand and incorporate the sachet water industry into an integrated drinking water platform.
