This study examined the relationship between the adoption of bio-fortified provitamin- A cassava varieties and farming households’ health outcomes using cross sectional data obtained from 318 cassava farmers in southeast Nigeria. The data was analysed using binary logistic regression, propensity score matching of treatment effects and percentages. The study found that number of children under five, household size, education of head of household, extension service, ownership of television, radio, mobile phone and tricycle, membership of cooperative societies, and access to credit were the significant predictors of adoption of pro-vitamin-A bio-fortified cassava varieties in the States. The study also found that the main constraints militating against adoption of pro-vitamin-A bio-fortified cassava include decaying of roots immediately after maturation,high cost of cassava stem, and high moisture content. The estimate of the effect of the adoption of bio-fortified pro-vitamin-A cassava varieties onincidence of vitamin-A deficiency related diseases was significant with an average treatment effect on the adopters of -0.463. The adoption of bio- fortified pro-vitamin-A cassava varieties has substantial effect on the reduction of vitamin-A deficiency related health outcomes. There is need for wider awareness and dissemination of the varieties among cassava farmers, while interventions should target the promotion of both production and consumption of such cassava varieties. Key words: adoption of bio-fortified cassava varieties; vitamin A deficiency related diseases
It has become difficult to articulate the impacts, needs and challenges of digitalization of agriculture due to the extensive nature of publications relating to the digitalization of the agricultural sector. This review evaluated the effect of digitalization of agriculture on improved food production and standard of living, identified the training needs of extension staff and clientele for digitalization of agriculture, and highlighted the challenges of digitalization of agriculture. From an initial search of 208 articles, only 87 articles met the inclusion criteria using the PRISMA guidelines. Most articles were published between 2016 and 2020; more studies were carried out in the South Western region of the country. Digitalization of agriculture has reduced the role of middlemen, provided opportunities for farmers to expand their markets, and improved the linkage between extension and research centers, and productivity and livelihood of small-scale farmers. Training needs for effective digitalization of agriculture were in skills, use of relevant digital services, digital privacy and security risks. Challenges of digitalization of agriculture were lack of technical skill, poor infrastructure and high cost of purchase and maintenance. The government should focus on initiating agricultural technology transfer programs and provide the necessary rural infrastructure to support the sector's digitalisation.
The paper analyzed the demand for imported rice, local rice, maize, and other cereals in Nigeria. Using the second wave data of the Nigerian Living Standard Measurements Survey -Integrated Survey on Agriculture, it employed the Quadratic Almost Ideal Demand System model for empirical analysis. The result indicates that the imported and local rice are proved to be normal goods. However, imported rice is a luxury item while local rice is a necessity. The compensated and uncompensated own-price elasticities for imported and local rice are negative, indicating that an increase in ownprice will decrease its own-demand in line with the law of demand. The estimates of uncompensated cross-price elasticity show that imported rice and local rice are complements in Nigeria. Finally, the study represents an effort to disaggregate food demand analysis to obtain useful information on price and other factors determining the demand for specific foods. Contribution/ OriginalityThis paper is an attempt to provide information on the demand for locally produced and imported rice in Nigeria and their views as either necessity and/or luxury commodities, across the different income quintiles, as well as in urban and rural areas across the country using the Quadratic Almost Ideal Demand System model.
An in-depth understanding of the impact of vulnerability on livelihoods and food security is important in deploying effective adaptation actions. The Nigerian agricultural sector is dominated by rainfed and non-homogenous smallholder farming systems. A number of climate change risk studies have emerged in the last decade. However, little attention has been given to vulnerability assessments and the operationalization of vulnerability. To highlight this shortcoming, this study systematically reviewed climate-change-focused vulnerability assessments in the agricultural sector by evaluating (1) variation in climate variables in Nigeria over time;(2) the state of climate change vulnerability assessment in Nigerian agriculture; (3) the theoretical foundations, operationalization approaches, and frameworks of vulnerability assessments in Nigeria; (4) the methods currently used in vulnerability assessments; and (5) lessons learned from the vulnerability studies. We used a linear trend of climatic data spanning over a period of 56 years obtained from the Nigerian Meteorological Agency and the Climate Research Unit of the University of East Anglia, United Kingdom, along with a systematic review of literature to achieve the objectives. The analysis indicates a significant and positive correlation between temperature and time in all major agro-ecological zones. For precipitation, we found a non-significant correlation between precipitation in the Sahel, Sudan, and Guinea Savanna zones with time, while the other zones recorded positive but significant associations between precipitation and time. The systematic review findings indicate no clear progress in publications focused specifically on vulnerability assessments in the Nigerian agricultural sector. There has been progress recently in applying frameworks and methods. However, there are important issues that require addressing in vulnerability assessments, including low consideration for indigenous knowledge and experience, unclear operationalization of vulnerability, non-standardization of vulnerability measures, and inadequacy of current assessments supporting decision making.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
