ECONOMIC ANALYSIS OF CASSVA PROCESSING AND MARKETING KOGI STATE, NIGERIA

CHAPTER ONE: INTRODUCTION

1.1 Background of the Study

Cassava (Manihot esculenta Crantz) is a perennial woody shrub of the Euphorbiaceae family, believed to have originated from Brazil and introduced to West African countries by the Portuguese during the colonial era . Over the centuries, cassava has become one of the most important staple food crops in Nigeria, serving as a primary source of dietary energy for millions of people, particularly in the rural areas where it is cultivated, processed, and consumed. The crop’s adaptability to poor soils, tolerance to drought and extreme conditions, and availability all year round have contributed to its widespread cultivation across the country.

Nigeria is the world’s largest producer of cassava, with annual production estimated at over 46 million metric tons, grown on approximately 3.85 million hectares of land with an average yield of about 11 tons per hectare . The country’s cassava production surpasses that of Thailand, Brazil, and Indonesia, which are also major cassava-producing nations. Despite this impressive production volume, Nigeria contributes only about 0.001% of the world export market for cassava products, compared to Thailand which accounts for about 50% of global cassava exports . This paradox of being the world’s largest producer yet a minor player in the global export market underscores the critical challenges facing the cassava value chain in Nigeria, particularly in the areas of processing and value addition.

The comparative disadvantage of Nigeria in the international cassava market can be attributed to several factors, including the high cost of production and processing, limited value addition, poor product quality, and inadequate processing technologies. The cost of production and processing in Nigeria is estimated at 104 US dollars per ton, compared to only 21 US dollars per ton in Thailand . This significant cost differential highlights the inefficiencies in the Nigerian cassava processing and marketing system, which are rooted in outdated processing technologies, inadequate infrastructure, limited access to credit, and the predominance of small-scale, informal processing operations.

Kogi State, located in the North-Central geopolitical zone of Nigeria, is one of the country’s leading cassava-producing states. According to the National Bureau of Statistics, Kogi State accounts for over 16% of Nigeria’s total cassava output, with more than 3.3 million metric tons produced annually . This has earned the state recognition as a cassava belt, with significant implications for agro-processing, food security, and raw material supply for numerous industries. The state’s agro-ecological conditions, including favourable climate, adequate rainfall, and fertile soils, make it particularly suitable for cassava cultivation, and the crop is grown across all 21 Local Government Areas of the state.

The importance of cassava in Kogi State extends beyond primary production to processing and marketing activities that provide employment and income for a large proportion of the rural population. The study by Daniel (2021) revealed that the majority of cassava processors and marketers in Kogi State are women (73%), predominantly of middle age between 31-50 years (66%), and married (67%) . The study also found that 37% of the respondents had 5-10 years of experience in processing and marketing, while 57% had large family sizes of about 5-10 persons, with 55% having between 4-6 family members directly assisting in processing and marketing activities . These findings highlight the role of cassava processing and marketing as a family-based enterprise, providing employment opportunities for women and the youth in rural areas.

Cassava processing is essential not only for value addition but also for removing the toxic cyanogenic glucosides naturally present in the raw tuber. Cassava contains substances known as cyanogenic glucosides, which break down into hydrocyanic acid (HCN) after harvest, making raw cassava poisonous for human consumption . Processing serves to reduce this toxicity, increase palatability, and extend the shelf life of the product. The major products derived from cassava include garri, cassava flour (alibo), fufu, starch, tapioca, sliced cassava chips (abacha), and other cassava-based products . Among these, garri, cassava flour, and fufu are the most commonly produced and marketed products in Kogi State.

The processing of cassava into various products follows distinct value chains, with each product requiring specific processing methods. The study by Daniel (2021) identified three main processing channels for cassava products in Kogi State . For garri processing, the majority of respondents (58%) adopted the channel comprising peeling-washing-grating-dehydration-fermentation and frying. For cassava flour, 70% of processors adopted the channel comprising peeling-washing-soaking-sifting-dewatering-molding and drying. For fufu processing, 88% adopted the channel comprising peeling-washing-soaking-fermentation-sifting-dewatering-boiling and molding . These processing methods are largely traditional, labour-intensive, and require significant time and physical effort.

The marketing of cassava products in Kogi State also follows specific channels that connect processors to final consumers. The study by Daniel (2021) found that the majority of garri marketers (60%) and cassava flour marketers (53%) adopted a marketing channel comprising packaging-transportation-wholesaling-retailing and final consumers, while the majority of fufu marketers (57%) adopted a marketing channel comprising packaging-retailing and final consumers . These marketing channels reflect the structure of the cassava value chain in the state, which is characterized by multiple intermediaries and limited direct linkages between producers and consumers.

The socioeconomic factors influencing cassava processing and marketing in Kogi State have been the subject of empirical investigation. The study by Daniel (2021) found that sex, level of education, amount of initial capital invested, family size, marital status, and age of respondents significantly influenced the output of cassava products . The study also revealed that 79.9% of the total variability in garri enterprise output was explained by these socioeconomic factors, while 62.7% and 81.1% of cassava flour and fufu enterprise profits respectively were explained by the same factors . These findings underscore the critical role of socioeconomic characteristics in determining the success and profitability of cassava processing and marketing enterprises.

The profitability of cassava processing and marketing enterprises in Kogi State is influenced by both variable and fixed costs. The study by Daniel (2021) found that the combined effects of all variables and fixed inputs in the profit function explained 78.9% of the variation in maximum variable profit for garri enterprises, while the combined effect of variable and fixed costs explained 80.1% and 84.4% of the variation in maximum variable profit for cassava flour and fufu enterprises respectively . The study rejected the null hypothesis that output and input prices do not significantly affect profit, confirming that price fluctuations and cost structures are critical determinants of enterprise profitability.

Recent policy initiatives and institutional frameworks have been established to support the development of the cassava value chain in Kogi State. The Kogi State Government, in collaboration with the Federal Government and development partners, is establishing two agro-industrial zones dedicated to cassava processing: the Ukpake Special Agro-Industrial Processing Zone (SAPZ) in Ajaokuta Local Government Area, spanning 254 hectares, and the Alape Staple Crop Processing Zone (SCPZ) in Kabba/Bunu Local Government Area . These zones are strategically located with access to electricity, water, gas pipelines, railway lines, and proximity to the proposed Adogo International Cargo Airport. The SAPZ is being positioned to host ethanol plants, flour and starch mills, and feed processors, while the SCPZ has attracted attention from major processors including Dangote, BUA, and Cargill International .

Several state and donor-funded programs have played a critical role in enhancing cassava productivity and processing capacity in Kogi State. The Agricultural Productivity Enhancement and Livelihood Improvement Support (APPEALS) Project has empowered local farmers with improved cassava stems, agro-inputs, mechanized tools, and training, increasing yields from an average of 10 tons per hectare to over 25 tons per hectare . The FADAMA III + AF and Value Chain Development Programme (VCDP) has provided input support, capacity building, and marketing linkages to over 4,000 farmers in the cassava value chain. Additionally, trained processors under these initiatives have adopted new technologies in cassava flour, starch, and ethanol production, driving forward the industrial utility of cassava as a raw material .

The Kogi State Government has also demonstrated commitment to agricultural transformation through the recently signed Food for Lagos partnership, aimed at creating a robust food supply chain between Kogi and Lagos States. This initiative is expected to boost food production, improve infrastructure, and attract high-value investments into the state’s agricultural sector . The government is implementing the Rural Access and Agricultural Marketing Project (RAAMP) to facilitate the rehabilitation of rural roads and improve access to markets, as well as the Agro-Climatic Resilience in Semi-Arid Landscapes (ACReSAL) project to channel investments into rural farming communities . These initiatives are complemented by the development of a Cassava Value Chain Policy to coordinate the sector’s growth from input supply and research to processing and marketing .

A groundbreaking initiative in Kogi State is the cassava peel-to-feed prototype processing facility, supported by the African Development Bank, Synergos Nigeria, and ILRI. This facility converts high-quality cassava peels into animal feed, reducing waste and creating a new product line from what was once discarded . Such innovations are key to the sustainable use of agro-based raw materials and reinforce the push for full value utilization. The Raw Materials Research and Development Council (RMRDC) has also emphasized the importance of value addition, with the proposed 30% Value Addition Bill aimed at encouraging local processing of raw materials and boosting economic growth and wealth creation .

Despite these policy initiatives and institutional frameworks, significant challenges remain in the cassava processing and marketing sector in Kogi State. A study by Daniel (2021) identified lack of capital for expansion, irregular power and water supply, fluctuation in prices of output, and irregular shapes as the most challenging constraints to cassava processing and marketing activities . These constraints limit the capacity of processors and marketers to invest in modern technologies, improve product quality, access premium markets, and increase their incomes. The study recommended the provision of finance and infrastructural facilities such as roads, water supply, and electricity to reduce the cost of processing and marketing cassava products .

The raw material supply gap remains a critical challenge for large-scale cassava processing facilities in Kogi State. Companies such as UNICANE and Crest Agro Products, which have large cassava processing facilities in the state, face raw material supply shortages despite being located in cassava-producing zones. Combined, they process over 2,500 metric tons of cassava per day but currently source less than 10% locally . This supply gap highlights the need for more investment in farmer cooperatives, rural storage systems, and cassava clusters, which can be facilitated through technical support and partnership development. The transformation of cassava from a subsistence crop to an industrial raw material requires coordinated efforts across the entire value chain.

The economic analysis of cassava processing and marketing in Kogi State is therefore timely and essential for understanding the dynamics of the cassava value chain, identifying the constraints and opportunities for growth, and providing evidence-based recommendations for policy and program interventions. This study aims to contribute to this understanding by examining the socioeconomic characteristics of cassava processors and marketers, analyzing the processing and marketing channels, assessing the profitability of cassava enterprises, identifying the constraints facing the sector, and proposing strategies for improving the efficiency and sustainability of cassava processing and marketing in Kogi State.

1.2 Statement of the Problem

The cassava processing and marketing sector in Kogi State, despite its significant potential and strategic importance to the state’s economy, faces numerous challenges that limit its growth, sustainability, and contribution to rural development. While Kogi State accounts for over 16% of Nigeria’s total cassava output, with more than 3.3 million metric tons produced annually , the full economic potential of this production remains largely unrealized due to constraints in processing, value addition, and marketing.

The first and most fundamental problem is the low level of value addition in cassava processing in Kogi State. Most cassava processors in the state adopt traditional, labour-intensive processing methods that are inefficient, time-consuming, and result in products of variable quality . These traditional methods limit the ability of processors to access premium markets, command higher prices, and increase their incomes. The lack of modern processing technologies and equipment restricts the range of products that can be produced and the quality standards that can be achieved, thereby limiting the competitiveness of Kogi State’s cassava products in both domestic and international markets.

The problem of inadequate access to finance is a critical constraint facing cassava processors and marketers in Kogi State. The study by Daniel (2021) found that about 50% of respondents obtained capital from their personal savings, while 52% indicated that their initial capital investment was between N20,000 and N39,000 . This limited capital base constrains the capacity of processors and marketers to invest in modern processing equipment, expand their operations, improve product quality, and access premium markets. The lack of access to formal credit and the high interest rates charged by informal lenders perpetuate a cycle of low investment, low productivity, and low income in the cassava processing sector.

The problem of inadequate infrastructure constitutes another significant constraint to cassava processing and marketing in Kogi State. Irregular power supply and inadequate water supply have been identified as major constraints to processing activities . These infrastructure deficits increase the cost of processing, reduce the efficiency of operations, and limit the quality and shelf life of products. Poor road networks and inadequate market infrastructure also constrain the marketing of cassava products, increasing transportation costs, limiting access to markets, and contributing to post-harvest losses. The lack of reliable infrastructure creates additional transaction costs that erode the profitability of cassava enterprises.

The problem of fluctuating prices of cassava products creates uncertainty and risk for processors and marketers. The study by Daniel (2021) identified fluctuation in prices of output as one of the most challenging constraints to cassava processing and marketing activities . Price volatility makes it difficult for processors and marketers to plan their operations, manage their finances, and invest in their enterprises. The risk of price fluctuations is exacerbated by limited market information, weak market linkages, and the absence of price stabilization mechanisms. This uncertainty discourages investment in value addition and limits the growth of the cassava processing sector.

The problem of limited access to improved processing technologies constrains the quality and efficiency of cassava processing in Kogi State. The study by Daniel (2021) noted that the irregular shapes of cassava products were a constraint to marketing, reflecting the limitations of traditional processing methods in producing standardized and uniform products . The adoption of modern processing technologies, including mechanized graters, hydraulic presses, and improved drying and packaging equipment, is limited by the high cost of equipment, lack of technical skills, and limited access to credit. This technological gap perpetuates the inefficiencies and quality limitations of traditional processing methods.

The problem of limited access to markets and market information constrains the marketing of cassava products in Kogi State. While the study identified marketing channels for garri, cassava flour, and fufu , many processors and marketers lack access to premium markets, including urban centers, industrial buyers, and export markets. The lack of market information, including information on prices, quality standards, and buyer requirements, limits the ability of processors and marketers to make informed decisions about what to produce, how to process, and where to sell. The reliance on traditional marketing channels with multiple intermediaries reduces the share of the final price that reaches the processor or marketer.

The problem of low levels of education and technical skills among cassava processors and marketers limits their capacity to adopt improved technologies, access information, and make informed business decisions. The study by Daniel (2021) found that 42% of respondents had no formal education . Low levels of education limit the ability of processors and marketers to understand market requirements, comply with quality standards, maintain proper financial records, and access information and support services. The lack of technical skills in modern processing methods and business management constrains the productivity and profitability of cassava enterprises.

The problem of limited institutional support for cassava processing and marketing constrains the development of the sector. While various programs, including APPEALS, FADAMA III + AF, and VCDP, have been implemented , their reach and impact have been limited, and many processors and marketers have not benefited from these interventions. The lack of coordinated and sustained institutional support, including extension services, training, credit, and market linkages, perpetuates the challenges facing the cassava processing and marketing sector. The weak institutional framework for supporting the cassava value chain limits the effectiveness of policy interventions and constrains the growth of the sector.

The problem of limited integration of cassava processors and marketers into value chains and the broader economy constrains their growth and sustainability. Many processors and marketers operate as isolated units, with limited connections to suppliers, buyers, and other enterprises in the value chain. The development of value chains, from production through processing to marketing, requires policy support for coordination, infrastructure, and linkages. The limited integration of processors and marketers into value chains constrains their access to inputs, technology, markets, and support services.

The problem of gender inequality in access to resources and support affects the development of cassava processing and marketing enterprises in Kogi State. While women dominate the sector (73%) , they may face unique constraints in accessing credit, training, technology, and markets. The study by Daniel (2021) found that sex was a significant factor influencing the output of cassava products , suggesting that gender differences affect the performance of processing and marketing enterprises. Gender-responsive policies and programs are needed to address the specific constraints faced by women processors and marketers.

The problem of limited data and information on cassava processing and marketing in Kogi State constrains effective policy formulation and program implementation. While some studies have been conducted, including the study by Daniel (2021) , there is limited comprehensive and up-to-date information on the socioeconomic characteristics of processors and marketers, the processing and marketing channels, the profitability of cassava enterprises, and the constraints facing the sector. The lack of reliable data makes it difficult for policymakers and development practitioners to design evidence-based interventions that effectively address the constraints faced by cassava processors and marketers.

The problem of limited attention to quality assurance and product standardization constrains the competitiveness of cassava products from Kogi State. The study by Daniel (2021) identified irregular shapes as a constraint to marketing , reflecting the lack of quality standards and quality assurance systems in the cassava processing sector. The absence of quality standards limits the ability of processors and marketers to access premium markets and command higher prices for their products. The development of quality standards and quality assurance systems is essential for improving the competitiveness of cassava products in both domestic and international markets.

The problem of limited access to improved packaging and storage facilities constrains the marketing and shelf life of cassava products. Traditional packaging methods and inadequate storage facilities contribute to product deterioration, post-harvest losses, and limited market reach. The lack of improved packaging and storage facilities limits the ability of processors and marketers to store products for extended periods, transport them to distant markets, and maintain their quality. The development of improved packaging and storage solutions is essential for reducing post-harvest losses and expanding market access for cassava products.

The problem of limited entrepreneurship and business management skills among cassava processors and marketers constrains the growth and sustainability of their enterprises. Many processors and marketers lack the business management skills needed to effectively manage their finances, plan their operations, make investment decisions, and access markets. The study by Daniel (2021) found that level of education and initial capital invested significantly influenced the output of cassava products , suggesting that business management skills and financial management capabilities are important determinants of enterprise performance. The development of entrepreneurship and business management skills is essential for improving the productivity and profitability of cassava processing and marketing enterprises.

The problem of limited climate resilience in cassava processing and marketing activities constrains the sustainability of the sector. The vulnerability of cassava production to climate variability, including drought and flooding, affects the supply of raw materials for processing and marketing activities. The limited adoption of climate-smart processing technologies and practices reduces the resilience of the sector to climate-related shocks. The development of climate-resilient processing and marketing strategies is essential for ensuring the sustainability of the cassava processing and marketing sector in Kogi State.

1.7 Significance of the Study

This study is significant for several reasons, contributing to academic knowledge, policy formulation, and practical enterprise development in Kogi State and Nigeria more broadly.

From a theoretical perspective, this study contributes to the body of knowledge on agricultural economics and value chain analysis in Nigeria. By examining the economics of cassava processing and marketing, the study provides empirical evidence that can validate or challenge existing theories on agricultural enterprise profitability, value addition, and market efficiency. The study adds to the growing literature on cassava value chain development in Nigeria and provides a basis for comparative analysis with other regions and countries. The findings contribute to the theoretical understanding of the relationship between socioeconomic factors, processing methods, and enterprise profitability.

The study has significant policy implications, providing evidence-based recommendations for improving cassava processing and marketing in Kogi State. Policymakers at the state and federal levels can use the findings of this study to design and implement effective policies and programs that address the specific needs and constraints of cassava processors and marketers in the state. The study’s findings on the socioeconomic factors influencing output and profit, the processing and marketing channels, and the constraints facing the sector provide a solid foundation for policy interventions aimed at improving the performance and sustainability of the cassava value chain. The identification of constraints and the proposed strategies for addressing these constraints offer practical guidance for policymakers.

For government agencies involved in agricultural development, including the Kogi State Ministry of Agriculture, the Raw Materials Research and Development Council (RMRDC), and the Agricultural Development Programme, this study provides insights into the challenges and opportunities in the cassava processing and marketing sector. The findings can guide the design and implementation of programs that effectively support cassava processors and marketers, including the provision of credit, training, infrastructure, and market linkages. The study’s findings on the effectiveness of current policy interventions and the areas requiring improvement can help agencies improve the impact of their programs.

For development partners and non-governmental organizations working in Kogi State, this study provides information that can guide their interventions in support of cassava value chain development. The study’s findings on enterprise characteristics, constraints, and opportunities can help development partners design and implement programs that complement government policies and address gaps in policy implementation. The identification of successful processing and marketing models and the factors contributing to their success can guide the replication and scaling up of effective approaches.

For cassava processors and marketers, this study provides information that can enhance their understanding of the cassava value chain and their capacity to improve their enterprises. The study’s findings on the factors influencing profitability, the processing and marketing channels, and the strategies for addressing constraints can help processors and marketers make informed decisions about their businesses. The identification of best practices and the strategies for improving efficiency and quality can guide enterprise development and growth.

The study has practical significance for economic development in Kogi State, providing evidence that can guide the transformation of the cassava value chain from subsistence to commercial production and processing. By identifying the opportunities and constraints in the cassava processing and marketing sector, the study contributes to the broader goals of economic diversification, employment generation, poverty reduction, and food security in the state. The study’s findings are particularly relevant in light of recent policy initiatives, including the establishment of agro-industrial zones, the Food for Lagos partnership, and various donor-funded programs.

The study is also significant for its focus on Kogi State, providing specific and detailed information on the economics of cassava processing and marketing in the state. While national-level studies on cassava exist, there is limited research that focuses specifically on Kogi State. This study fills this gap by providing state-level data and analysis that can inform state-specific policies and programs. The findings are particularly relevant in light of Kogi State’s strategic positioning as Nigeria’s cassava industrial powerhouse and the various policy initiatives aimed at developing the cassava value chain in the state .

1.8 Scope of the Study

The study focuses on the economic analysis of cassava processing and marketing in Kogi State, Nigeria. Geographically, the study covers Kogi East Senatorial District of Kogi State, which is one of the major cassava-producing areas in the state. This coverage ensures that the study captures the diversity of cassava processing and marketing activities in the state’s major cassava-producing region. The selection of Kogi East Senatorial District is justified by its prominence in cassava production and the concentration of processing and marketing activities in the area .

Conceptually, the study examines the economics of cassava processing and marketing, including the socioeconomic characteristics of processors and marketers, the processing and marketing channels adopted, the profitability of cassava enterprises, the factors influencing output and profit, and the constraints facing the sector. The study covers three major cassava products: garri, cassava flour, and fufu, which are the most commonly processed and marketed products in the study area .

The study focuses on small-scale cassava processors and marketers operating in the informal sector, who constitute the majority of actors in the cassava value chain in Kogi State. The focus on small-scale processors and marketers is justified by their importance in the cassava value chain, their contribution to employment and income generation, and the particular constraints they face in accessing resources and support.

In terms of coverage, the study examines the cassava processing and marketing activities in the study area during the 2020/2021 production season. The study draws on primary data collected from 120 cassava processors and marketers selected through a multistage sampling technique . The study also reviews relevant literature, policy documents, and secondary data sources to provide context and complement the primary data.

Methodologically, the study employs a survey research design, using structured questionnaires and interview schedules to collect primary data from sampled cassava processors and marketers. The study employs descriptive statistics, multiple regression analysis, profit function analysis, and likert scale rating techniques to analyze the data . These analytical techniques are appropriate for describing the characteristics of respondents, identifying the factors influencing output and profit, assessing profitability, and ranking the seriousness of constraints.

1.9 Limitation of the Study

The study acknowledges several limitations that may affect the interpretation and generalizability of the findings.

The first limitation relates to the geographical scope of the study. While the study covers Kogi East Senatorial District, the findings may not be generalizable to other parts of Kogi State or to other states with different cassava value chains and socioeconomic contexts. The specific conditions in Kogi East Senatorial District, including its agro-ecological characteristics, infrastructure, and institutional context, may differ from those in other areas of the state, limiting the applicability of the findings. However, the selection of Kogi East Senatorial District, which is one of the major cassava-producing areas in the state, enhances the relevance of the findings for the broader cassava sector in Kogi State.

The study is also limited by the sampling technique employed. While efforts were made to select a representative sample of 120 cassava processors and marketers using a multistage sampling technique , the sample size may not fully capture the diversity of cassava processing and marketing enterprises in the study area. The study may not adequately represent certain categories of processors and marketers, such as those in remote areas or those engaged in processing less common cassava products, due to sampling constraints. However, the sample size of 120 respondents is consistent with similar studies in the field and provides a reasonable basis for analysis.

The reliance on primary data collected through structured questionnaires presents several limitations. Respondents may not accurately recall or report information on their processing and marketing activities, costs, revenues, and constraints. Self-reporting bias may affect the accuracy of the data and the validity of the findings. To address this limitation, the study employed careful questionnaire design, trained enumerators, and triangulation with secondary data sources where possible. The use of multiple analytical techniques also helps to validate the findings.

The study is limited by the cross-sectional nature of the research design. The data were collected at a single point in time, capturing the situation of cassava processors and marketers at that particular moment. This design does not capture seasonal variations in processing and marketing activities, changes in enterprise performance over time, or the dynamic effects of policy interventions. A longitudinal study that follows processors and marketers over a period of time would provide richer insights into the economics of cassava processing and marketing, but such a design was beyond the scope of this study.

The study is also limited by the challenge of measuring profitability and efficiency in small-scale, informal enterprises. Many processors and marketers do not keep formal financial records, making it difficult to accurately estimate costs, revenues, and profits. The study relied on respondents’ recall and estimates, which may be subject to error. The use of profit function analysis helps to address this limitation by estimating profitability based on reported costs and revenues, but the accuracy of the estimates depends on the quality of the data provided by respondents.

The study acknowledges the challenge of isolating the effects of specific factors on enterprise performance. The profitability of cassava processing and marketing enterprises is influenced by multiple factors, including socioeconomic characteristics, processing methods, market conditions, infrastructure, and institutional support. Isolating the specific effects of individual factors is challenging, and the study may not fully capture the complexity of the relationships. The study attempted to address this limitation by using multiple regression analysis to identify the significant factors influencing output and profit, but the analysis may not capture all relevant factors.

The study is limited by the available time and resources for data collection and analysis. While the study aimed to provide comprehensive coverage of the topic, the scope and depth of the analysis were constrained by the resources available. A more extensive study with a larger sample size, more detailed data collection, and longer time frame would provide more robust findings and richer insights into the economics of cassava processing and marketing.

The study is limited by the potential for researcher bias in the interpretation and analysis of the data. Despite efforts to maintain objectivity, the researcher’s own experiences, values, and perspectives may have influenced the research process, including the selection of variables, the interpretation of findings, and the formulation of recommendations. To minimize this bias, the study employed objective analytical techniques and sought input from peers and experts in agricultural economics and value chain analysis.
