The study was conducted to investigate the demand and consumption of bananas in Tanzania. The study utilized cross sectional data (2021) and time series data (2000–2021). The demand and consumption models were used as analytical tools. Key variables including price, income levels, and preferences were examined to understand their influence on banana demand and consumption. Results shows that elasticity of own price of banana was negative ranging from − 0.11 to -0.13 and statistically significant at 10% level. Cross-price elasticity with respect to cassava ranged from 0.06 to 0.08 and for sweet potatoes was 0.24. The income elasticity was positive ranging from 0.04 to 0.07 but significant. The elasticities of banana demand vary between urban and rural areas. Consumers in urban and rural areas was responsive to price stimuli. Price elasticities ranged from − 0.33 to -1.15 in urban areas and from − 0.48 to -1.01 in rural areas. The income elasticities were positive and significant for all regions. It is concluded that banana consumption was attributed to relative food prices, income, changing tastes and preferences. Consumption demand elasticity income Musa spp 1.0 Introduction Bananas (Musa spp.) are one of the most important staple foods in Tanzania, contributing significantly to food security, income generation, and rural livelihoods [ 1 ]. Tanzania is among the top banana-producing countries in Africa, with diverse varieties cultivated across different agro-ecological zones [ 2 ]. Bananas are not only consumed fresh but also processed into various products such as banana chips, juice, and flour, adding value to the crop and expanding market opportunities [ 3 ]. The consumption of bananas in Tanzania is deeply ingrained in the cultural and dietary practices of both urban and rural populations [ 4 ]. Bananas are rich in essential nutrients such as potassium, vitamins, and dietary fiber, making them a valuable component of a balanced diet [ 5 ]. Additionally, bananas serve as a source of income for millions of smallholder farmers, especially in rural areas where agriculture is the primary livelihood [ 2 ]. Despite their importance, several challenges threaten the sustainability of banana production and consumption in Tanzania. These include pests and diseases such as Fusarium wilt (Panama disease) and Banana Xanthomonas Wilt (BXW), which can devastate banana plantations and reduce yields [ 6 ]. Moreover, inadequate infrastructure, post-harvest losses, and market inefficiencies hinder the development of the banana value chain [ 2 ]. The crop occupies a strategic position in Tanzania’s economy contributing greatly to the internal exchange economy and providing national food security. However, despite the decline in consumption of bananas, the consumer demand for bananas in Tanzania and the magnitude to which the major determinants, namely price, income and preference influence its demand and consumption is not yet fully understood. This applies to the consumer demand of many other food crops ([ 7 , 8 ]. Demand is a multivariate relationship, that is, it is determined by many factors simultaneously. Some of the most important determinants of market demand for a particular product are own price, consumer income, prices of other commodities, consumer’s taste and preferences. Income distribution, total population, consumer’s wealth, credit availability, government policy and past levels of demand and income [ 9 ]. A complex web of interactions, however, between policies, income and prices contribute to access to food and therefore, food security [ 10 ]. While knowledge of the average price response of populations may be sufficient to determine a market-clearing price, it will not enable one to know how different parts of a population will change their consumption following a price change [ 10 ]. Furthermore, the absence of information on commodity substitution limits a planner’s ability to influence the consumption of specific groups through price changes without introducing disincentives, costly general subsidies, or targeting schemes that would strain the administrative resources of a country. Consumption research is therefore, as important as food security research because it can answer two basic questions. First, had the decrease/increase in consumption in recent years been a response to availability, change inn taste and preferences or to relative prices of banana substitute? If it is the later, they are reversible and subject to change through price policy. If it is due to changing tastes and preference, then it may prove difficult to “turn back the clock”. Second, how to consumption patterns vary by income groups? The objectives of the study were therefore, to analyze the consumption trends of bananas in Tanzania; to determine consumption in relation to prices and income; identify the possible implications of consumption on production and vice-versa and suggest policies regarding consumption relationship and food security. 2.0 Materials and Methods 2.1 Research design The study adopted both cross-sectional data (2020/21) and time series data (2000–2021). The cross-sectional data provides a snapshot of banana consumption and demand at a particular point in time across selected major towns of Tanzania. It allowed researchers to analyze variations in consumption patterns among different population segments. In addition, cross-sectional data helped to identify factors such as income levels, preferences that influence banana consumption at a specific point in time. On the other hand, time series data helped to analyze the factors evolved over time and their impact on consumption. By combining both types of data, researchers can better understand the complex interactions between these factors and their influence on banana demand. 2.2 Data sources The data were obtained from Ministry of Agriculture, Food Security and Cooperatives and the 2020/21 Tanzania Household Budget Survey Report. The primary data were collected through survey using a structured questionnaire to obtain information from the respondents. 2.23 Analytical methods The general form of the demand function was specific as shown in Eq. 1: $$DEMAND=f\left(Prices, Income, Family size, Dummy, Tastes\right)\dots \dots \dots \dots \dots \dots \dots .\dots \dots \dots \dots .\left(1\right)$$ A theoretical demand curve was based on the assumption that consumers seek to maximize utility subject to an income constraint (Koutsoyiannis, 1988). Thus, consumers are faced with a problem of choosing the specific goods and services that best satisfy their needs with the limits imposed by income. Quantity adjustments do not take place instantaneously because of imperfect knowledge, rigidities in consumer habits. Consumer uncertainty, etc. to account for the adjustment process, lagged demand for banana was included as an exploratory variable. A linear trend was included to account for changing tastes and preferences within the population. The constant elasticity demand function was used in the specification of the model. This captured the problem of simultaneous change of all the determinants, through this made it difficult to assess the influence of each individual factors separately. The model was also dynamized to express the generally accepted idea that current decision was influenced by past behavior. Banana, being a non-durable commodity, past purchases do reflect a habit which is acquired by buying and consuming the commodity in the past, so that the level of purchases in previous periods influences the current (and future) patterns of demand. Since capital accumulation in third world countries, Tanzania in particular, is negligible, lagged income will not be considered in the distributed lagged dynamic constant elasticity model to be specified. The assumption of “no money illusion” postulated by the traditional theory of the consumer has been taken note of by expressing the demand function as a homogenous function of degree zero (Koutsoyiannis, 1988). $${Q}_{x}={b}^{0}{\left(\frac{{P}_{x}}{CPI}\right)}^{{b}^{1}}+{\left(\frac{{P}_{y}}{CPI}\right)}^{{b}^{2}}+{\left(\frac{Y}{CPI}\right)}^{{b}^{3}}\dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \left(2\right)$$ Where: \({Q}_{x}=\) Quantity demanded \(CPI=\) Consumer Price Index \(Y=\) Income \(P\left(x,y\right)=\) Prices $${b}^{0} - {b}^{3}= \text{C}\text{o}\text{e}\text{f}\text{f}\text{i}\text{c}\text{i}\text{e}\text{n}\text{t}\text{s}$$ If the prices and income change by the same proportions, the quantity demanded of a commodity will not change because constants appear in both numerator and denominator which cancel out. The new quantity demanded will be the same as the initial one, that is, there is no money illusion in the behavior of the consumer. The quantity of a commodity consumed in any period is assumed to be equal to total domestic production plus imports less exports and waste. In case of bananas in Tanzania, the imports and exports are negligible. Therefore, total consumption is the total production less wastes: $${DB}^{t}={\partial }_{0}+{\partial }_{1}ln{RPB}^{t}+{\partial }_{2}ln{RPCa}^{t}\left({lnRPS}^{t}\right)+{\partial }_{3}ln{Y}^{t}+{\partial }_{4}{DB}^{t-1}+{\partial }_{5}T+{\partial }_{6}DV+{U}^{t}\dots \dots \dots \dots \left(3\right)$$ Where: \({DB}^{t}=\) Quantity of bananas consumed per capita in Thousands of metric tons, in year \(t\) \({RPB}^{t}=\) Retail price of bananas in Shillings per metric ton, in year \(t\) \({RPCa}^{t}=\) Retail price of cassava in Shillings per metric ton, in year \(t\) \({RPS}^{t}=\) Retail price of Sweet potatoes in Shillings per metric ton, in year \(t\) \({Y}^{t}=\) Per capita income in shillings, in year \(t\) \({DB}^{t-1}=\) Quantity of bananas consumed per capita in thousands of metric ton, in year \(t-1\) \(T=\) Tastes and preferences trend value, 2000 = 1, 2001 = 2, etc. \(DV=\) Dummy variable to reflects the 1978-80 war (1978-80 = 1, 0 otherwise). \({U}^{t}=\) Random error term \({\partial }_{0}-{\partial }_{6}=\) Variable coefficients \(t=\) Current year. 3.0 Results and Discussion 3.1 Regression coefficients for banana demand function Table 1 shows that coefficient (elasticity) of own price of banana was negative and statistically significant at 10% level. In the short run, it ranged between − 0.11 and − 0.13. This implies that, other factors being equal, an increase of 10% in the price of bananas would reduce the demand between 1.1 and 1.3%. The low elasticities are not unreasonable given the fact that banana is taken to be superior to its close substitutes (root crops and cereal crops) especially among the urban dwellers. Also, an increase in its price will reduce demand in favour of the substitutes by only small percentage. Cross-price elasticity with respect to cassava ranged from 0.06 to 0.08 in the short run and that for sweet potatoes was 0.24 in the short run. Apparently, consumers prefer cassava to sweet potatoes, which in turn preferred to maize as substitute for bananas in that order.

The income elasticity was positive but significant. It ranged between 0.04 and 0.07 in the short run. Therefore, as income increases, the demand for bananas increases. This conform to a priori economic theory. The coefficient for lagged consumption of banana ranged between 0.34 and 0.61 and was significant \(\left(P=0.17\right)\) . The trend variable has a negative and significant coefficient at 6% 8% levels. This suggests a negative growth rate in consumption attributed to decline in production. The income elasticity was positive but significant. It ranged between 0.04 and 0.07 in the short run. Therefore, as income increases, the demand for bananas increases. This conform to a priori economic theory. The coefficient for lagged consumption of banana ranged between 0.34 and 0.61 and was significant \(\left(P=0.17\right)\) . The trend variable has a negative and significant coefficient at 6% 8% levels. This suggests a negative growth rate in consumption attributed to decline in production. The coefficient for Dummy Variable (DV) was positive and insignificant coefficient. This implies that during periods of war in Tanzania (1978/1980), the demand for bananas, just like other food commodities and necessities, increased. Probably, people diverted their incomes to ensure that they had enough food. The explanatory power of the demand model for bananas, the adjusted coefficient of determination \(\left({R}^{2}\right)\) , implied that 86–90% of the variation in the dependent variable is explained by the explanatory variables (own price, substitute food prices, income, dummy variables (war). 3.2 Elasticity of banana demand function in rural and urban areas Field survey data indicated that, consumers were responsive to price stimuli. An increase in price was accompanied by a decrease in the per capita consumption. Price elasticities ranged from − .0.33 to -1.15 in urban areas and − 0.48 to -1.01 in rural areas (Table 2 ). Table 2 Elasticities of banana demand functions in urban and rural areas of Tanzania Dar es Salaam Mwanza Mbeya Arusha Tanga Urban urban rural Urban Rural Urban Rural Urban Own price elasticity -1.1 -1.15 -1.01 -0.79 -0.54 0.33 -0.48 -0.71 Income elasticity of demand 0.77 1.05 0.65 0.63 0.85 -0.33 0.49 0.64 Adjusted R-square 0.42 0.41 0.55 0.38 0.30 0.54 0.46 0.32 A 10% increase in own price of bananas reduced consumption by 3.3 to 11.5%. Short run income elasticities were found to be positive for all regions and major towns and significant \(\left(P=0.1\right)\) . As incomes increases therefore, the demand for banana increases. The income elasticities therefore, imply that a 10% increase in the per capita income is postulated to induce increased per capita consumption of banana between 4.5% − 8.5% in the short run. The explanatory power of the presented demand model, the adjusted coefficient of determination ranges between extremes of 0.30 and 0.55. Among urban consumers, banana was found to be necessity food item with the exception of Mwanza town. Where banana features as luxury food item, it implies that banana may not be a staple food crop in that area. Conclusion This study provides valuable insights into the demand and consumption of bananas in Tanzania. The analysis revealed the significant importance of bananas as a staple food in both urban and rural areas, serving as a source of nutrition and income for millions of people. Through time series regression analysis, we identified key factors influencing banana demand. tastes and preferences are changing from banana to cassava and sweet potatoes and relative food prices do not contribute much to changing tastes and preferences. Additionally, the estimation of elasticities highlighted variations in demand responsiveness between urban and rural contexts. The findings underscore the importance of tailored interventions to promote sustainable banana consumption in Tanzania. Improving market infrastructure, and addressing socio-economic disparities are critical steps towards ensuring food security and improving livelihoods for banana farmers and consumers. Moreover, value addition and market diversification strategies can unlock new opportunities for income generation and economic growth in the banana sector. Moving forward, policymakers, stakeholders, and development partners must prioritize evidence-based decision-making and collaborative efforts to address the challenges facing the banana value chain. By implementing targeted interventions informed by the findings of this study, Tanzania can unlock the full potential of its banana sector, contributing to enhanced food security, economic development, and improved well-being for its citizens. This study serves as a foundation for policy formulation aimed at promoting sustainable agricultural development and addressing food security challenges in Tanzania and beyond.

By combining both types of data, researchers can better understand the complex interactions between these factors and their influence on banana demand.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec4\" class=\"Section2\"\u003e \u003ch2\u003e2.2 Data sources\u003c/h2\u003e \u003cp\u003eThe data were obtained from Ministry of Agriculture, Food Security and Cooperatives and the 2020/21 Tanzania Household Budget Survey Report.

Thus, consumers are faced with a problem of choosing the specific goods and services that best satisfy their needs with the limits imposed by income. Quantity adjustments do not take place instantaneously because of imperfect knowledge, rigidities in consumer habits. Consumer uncertainty, etc. to account for the adjustment process, lagged demand for banana was included as an exploratory variable. A linear trend was included to account for changing tastes and preferences within the population. The constant elasticity demand function was used in the specification of the model. This captured the problem of simultaneous change of all the determinants, through this made it difficult to assess the influence of each individual factors separately. The model was also dynamized to express the generally accepted idea that current decision was influenced by past behavior. Banana, being a non-durable commodity, past purchases do reflect a habit which is acquired by buying and consuming the commodity in the past, so that the level of purchases in previous periods influences the current (and future) patterns of demand.\u003c/p\u003e \u003cp\u003eSince capital accumulation in third world countries, Tanzania in particular, is negligible, lagged income will not be considered in the distributed lagged dynamic constant elasticity model to be specified. The assumption of \u0026ldquo;no money illusion\u0026rdquo; postulated by the traditional theory of the consumer has been taken note of by expressing the demand function as a homogenous function of degree zero (Koutsoyiannis, 1988).\u003cdiv id=\"Equb\" class=\"Equation\"\u003e\u003cdiv format=\"TEX\" class=\"mathdisplay\" id=\"FileID_Equb\" name=\"EquationSource\"\u003e\n$${Q}_{x}={b}^{0}{\\left(\\frac{{P}_{x}}{CPI}\\right)}^{{b}^{1}}+{\\left(\\frac{{P}_{y}}{CPI}\\right)}^{{b}^{2}}+{\\left(\\frac{Y}{CPI}\\right)}^{{b}^{3}}\\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\dots \\left(2\\right)$$\u003c/div\u003e\u003c/div\u003e\u003c/p\u003e \u003cp\u003eWhere:\u003c/p\u003e \u003cp\u003e \u003cspan class=\"InlineEquation\"\u003e \u003cspan class=\"mathinline\"\u003e\\({Q}_{x}=\\)\u003c/span\u003e \u003c/span\u003e Quantity demanded\u003c/p\u003e \u003cp\u003e \u003cspan class=\"InlineEquation\"\u003e \u003cspan class=\"mathinline\"\u003e\\(CPI=\\)\u003c/span\u003e \u003c/span\u003e Consumer Price Index\u003c/p\u003e \u003cp\u003e \u003cspan class=\"InlineEquation\"\u003e \u003cspan class=\"mathinline\"\u003e\\(Y=\\)\u003c/span\u003e \u003c/span\u003e Income\u003c/p\u003e \u003cp\u003e \u003cspan class=\"InlineEquation\"\u003e \u003cspan class=\"mathinline\"\u003e\\(P\\left(x,y\\right)=\\)\u003c/span\u003e \u003c/span\u003e Prices\u003cdiv id=\"Equc\" class=\"Equation\"\u003e\u003cdiv format=\"TEX\" class=\"mathdisplay\" id=\"FileID_Equc\" name=\"EquationSource\"\u003e\n$${b}^{0} - {b}^{3}= \\text{C}\\text{o}\\text{e}\\text{f}\\text{f}\\text{i}\\text{c}\\text{i}\\text{e}\\text{n}\\text{t}\\text{s}$$\u003c/div\u003e\u003c/div\u003e\u003c/p\u003e \u003cp\u003eIf the prices and income change by the same proportions, the quantity demanded of a commodity will not change because constants appear in both numerator and denominator which cancel out.

In the short run, it ranged between − 0.11 and − 0.13. This implies that, other factors being equal, an increase of 10% in the price of bananas would reduce the demand between 1.1 and 1.3%. The low elasticities are not unreasonable given the fact that banana is taken to be superior to its close substitutes (root crops and cereal crops) especially among the urban dwellers. Also, an increase in its price will reduce demand in favour of the substitutes by only small percentage. Cross-price elasticity with respect to cassava ranged from 0.06 to 0.08 in the short run and that for sweet potatoes was 0.24 in the short run. Apparently, consumers prefer cassava to sweet potatoes, which in turn preferred to maize as substitute for bananas in that order.\u003c/p\u003e \u003cp\u003e \u003c/p\u003e\u003cdiv

Through time series regression analysis, we identified key factors influencing banana demand. tastes and preferences are changing from banana to cassava and sweet potatoes and relative food prices do not contribute much to changing tastes and preferences. Additionally, the estimation of elasticities highlighted variations in demand responsiveness between urban and rural contexts.\u003c/p\u003e\u003cp\u003eThe findings underscore the importance of tailored interventions to promote sustainable banana consumption in Tanzania. Improving market infrastructure, and addressing socio-economic disparities are critical steps towards ensuring food security and improving livelihoods for banana farmers and consumers. Moreover, value addition and market diversification strategies can unlock new opportunities for income generation and economic growth in the banana sector.\u003c/p\u003e\u003cp\u003eMoving forward, policymakers, stakeholders, and development partners must prioritize evidence-based decision-making and collaborative efforts to address the challenges facing the banana value chain. By implementing targeted interventions informed by the findings of this study, Tanzania can unlock the full potential of its banana sector, contributing to enhanced food security, economic development, and improved well-being for its citizens. This study serves as a foundation for policy formulation aimed at promoting sustainable agricultural development and addressing food security challenges in Tanzania and beyond.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eData availability\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe author confirms that all data generated or analyzed during this study are included in this manuscript paper.

The study was conducted to investigate the demand and consumption of bananas in Tanzania. The study utilized cross sectional data (2021) and time series data (2000\u0026ndash;2021). The demand and consumption models were used as analytical tools. Key variables including price, income levels, and preferences were examined to understand their influence on banana demand and consumption. Results shows that elasticity of own price of banana was negative ranging from \u0026minus;\u0026thinsp;0.11 to -0.13 and statistically significant at 10% level. Cross-price elasticity with respect to cassava ranged from 0.06 to 0.08 and for sweet potatoes was 0.24. The income elasticity was positive ranging from 0.04 to 0.07 but significant. The elasticities of banana demand vary between urban and rural areas. Consumers in urban and rural areas was responsive to price stimuli. Price elasticities ranged from \u0026minus;\u0026thinsp;0.33 to -1.15 in urban areas and from \u0026minus;\u0026thinsp;0.48 to -1.01 in rural areas. The income elasticities were positive and significant for all regions. It is concluded that banana consumption was attributed to relative food prices, income, changing tastes and preferences.\u003c/p\u003e","manuscriptTitle":"\"Demand and Consumption of Bananas (Musa spp.) in Tanzania\"","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-07-01 08:28:28","doi":"10.21203/rs.3.rs-4475344/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2024-11-14T05:19:02+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-11-09T03:34:07+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-10-06T08:37:56+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"260124188416131762213989268406819001953","date":"2024-10-01T15:01:52+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"59269157265362616927288362116360868325","date":"2024-09-28T21:29:15+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"32086118445392625666159724759893082686","date":"2024-09-27T10:10:40+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"198278272867851844953605082137073249594","date":"2024-08-08T10:11:27+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"1485499967653286787753683043409020694","date":"2024-07-07T19:10:10+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2024-07-05T16:07:15+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-06-18T05:33:37+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-06-14T06:22:34+00:00","index":"","fulltext":""},{"type":"submitted","content":"Discover Food","date":"2024-05-25T06:09:12+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
