“…Indicatively, consumers shift their preference towards fish or egg with increase in age as it is always recommended for the aged due to its content. This result agrees with the findings of Igwe and Onyekwere (2007) and Sharu (2000) on their work on meat demand in Umuahia and Sokoto Metropolis of Nigeria, respectively.…”

The study analyzed the demand for beef in western zone of Bauchi State, Nigeria. It specifically described the socio-economic characteristics of beef consumers; estimated the effects of socio-economic characteristics of the respondents on the demand for beef; described the pattern of beef demand; described the spatial and temporal price variability of beef; determined the factors affecting the demand for beef; and identified and described the constraints affecting the demand for beef in the study area. A multi-stage sampling technique was used to select 341 respondents from the study area. Out of the 341 questionnaire administered to the sampled households, 335 copies were correctly filled and eligible for data analysis; giving a response rate of 98%. Also, 10 beef marketers were randomly selected from the major markets in the study area. Data collected were analyzed using descriptive and inferential statistics. The results showed a mean age of 43 years among the respondents, with an average monthly income of N23,575 and a mean monthly expenditure on food items of N24,416. The coefficients of household size, education, and monthly income positively influenced the quantity of beef demanded at P<0.01 level of significance; and age of the household head inversely influenced the quantity of beef demanded. Furthermore, 70% of the respondents consumed beef frequently and beef was rated as the most (67.5%) preferred, egg (35.2%) and fish (26.3%) products. The spatial and temporal price variability analysis showed fair level of fluctuations with a rise in price of beef in 2019. Beef prices were volatile especially in Birshi market which had the highest price value of ₦1,800 per kilogram. The price of beef, household expenditure on other food items, and distance to the market significantly (P<0.01) reduced the quantity of beef demanded; and price of mutton significantly and positively (P<0.01) affected the demand for beef. Low monthly income (-0.843), preference for substitutes (0.764) and low nutritive value (0.589) were the major constraints to beef demand among households in the study area. The study concluded and recommended that increase in households’ income and reducing beef prices would be an effective strategy to increase the quantity of beef demanded, as it will uplift households’ relative purchasing power.

“…The literature review identified only a small number of studies that examined Nigerian consumers' demand for meat products; however, none used nationally representative country samples, and most used small cross-sectional samples (Igwe and Onyekwere 2007; 2 Gibson and Kim (2011) can also be seen both as a comparison of demand estimation results using different datasets and an assessment of econometric procedures used to account for infrequency of purchases. Alimi 2013;Ogundari 2012).…”

Hidden consumption is a potential problem when consumers’ expenditure data from household surveys are used in demand analyses. A solution is to collect and use actual consumption data. This study compares demand estimation using consumption and expenditure data and evaluates meat demand in Nigeria. Data are from a nationally representative panel from Nigeria. The results show the elasticities estimated across both datasets were very similar; thus, if the only objective of data collection is to estimate elasticity using a demand system framework, collection of both types of data (consumption and expenditures) may be unnecessary. The elasticity estimates classify poultry, beef, and processed seafood as luxuries, while other meat and unprocessed seafood are classified as necessities. Own-price elasticities from both datasets indicated that poultry, beef, and processed seafood were price-elastic, and poultry was the most price-elastic.

Of recent, adsorption process has gained a lot of attention as a cheap and effective means of removing trace metals from wastewater prior to discharge into water bodies. Being flexible in design and operation, the process has enabled an optimal recovery of trace metals such that the treated effluents meet the desired standards for waste disposal. Mercury is a toxicant released into the environment from natural and anthropogenic sources. It is notorious for having an unusual tendency to bio‐accumulate and persist in the food chain. Presence of mercury in food, especially those of aquatic sources has drastic implications on human health. Therefore, efforts have been made to develop and optimize low‐cost activated carbon (AC) as adsorbents for scavenging mercury from aqueous effluents. Herein, how mercury accumulates across the food chain, its health implications, and the recent advancement in the use of low‐cost ACs as adsorbent for trapping mercury from wastewater are highlighted. Relationship between the mercury removal efficiency and the surface morphology of the adsorbents as well as the influence of prevailing experimental condition on the sorption process were addressed. Challenges and future prospects of the use of low‐cost adsorbents in addressing mercury pollution in the environment are discussed.
