Data were collected from 100 cassava processors (22 males and 78 females) and analysed to describe socio-economic characteristics, identify and describe various technologies used in cassava processing, ascertain gender roles, estimate the influence of socio-economic characteristics on income of processors, determine profitability and identify constraints militating against the processors of cassava in the study area. Multi- stage random sampling techniques were employed in the selection of local government areas, communities and processors on who structured questionnaires were administered. Descriptive statistics, gross margin, rate of return on investment and multiple regressions were used for analysis. Results shows that majority of the processing fell within the middle age group (31 – 50 years) with an average years of processing experience of 22 years; mostly women with an average of 8 persons per household and 7 years of schooling. Traditional technologies were employed by the cassava processors with low level of men’s involvement relative to high involvement of women in cassava processing activities. Six out of nine explanatory variables were significantly related to income. These include; age, gender, education, experience, access to credit and number of labourers in the cassava processing enterprise. Processing cassava into garri and pellets were profitable, although processing cassava into garri was more profitable with gross margin of 22,700 and profitable index (PI) of 0.04 than pellets with gross margin of 13,100 with profitable index (PI) of 0.33. The major constraints facing the cassava processors in the study area include: poor storage facilities, high cost of processing inputs, poor road network for the transportation, bulkiness of fresh tubers, unstable weather and shortage of labour. The study therefore recommended that improved cassava processing technologies should be made available to the processors to enhance productivity and acceptability of their products, capacity building of the cassava processors for their improved profitability in the cassava processing enterprise, regular visits by agricultural extension agents for quick adoption of improved cassava processing technologies, stabilization of prices of agricultural commodities through the provision of a functional marketing channel and provision of storage facilities with good road network for improved production. CHAPTER ONE INTRODUCTION 1.1 Background Information The food problems in Nigeria and other developing countries can be reduced or even eliminated by intensifying agricultural production (Asiedu, 1989). It is based on this that emphasis of agricultural research for many years has been mainly on increased food production. One of the crops where considerable increased production level has been noticed is cassava. Nigeria is the world's largest producer with the total production of 38 Million tonnes in 2005 (Food and Agricultural Organization, 2006). The major area where the crop is grown extends from the south coast to the middle belt (Ogbe, Dixon and Alabi, 2003). By zone, the North Central produces about 7 million tonnes of cassava a year thus ranking first on the per capita basis of 0.72 tonnes/person in 2002 (PCU, 2003). Within the zone Benue and Kogi are the largest producers of cassava in the country (IITA, 2004). Cassava was introduced m the republic of Congo from South - America about 400 years back (Nweke, 2004) and it forms the staple part of the diet in many of the African countries. Since its introduction, it has spread through Sub-Saharan African to become the dominant staples in the diet of the people. Brazil, Indonesia, Nigeria, Thailand and Zaire are the biggest producers, each producing over 10 million tones and together accounting for over 63 percent of World's production (CBN, 2004).

This study aimed to discover the dietary diversity and determine the nutritional contribution of the Ivorian traditional dishes. Methodology and results : For that, a family food survey was conducted in forty-four localities in different regions (North, South, East, Center and West). Households from these localities were interviewed using a questionnaire. The interview focused on the preparation of the most commonly consumed traditional dishes, selected based on the consumption frequency. Then, the physico-chemical characteristics of these dishes were determined . The results showed that Ivorian traditional dishes consist mainly of starchy basic dishes and side sauces . The main dishes consist of tubers and roots (yam, cassava, potato) or cereals (rice, corn, millet, sorghum.) and starchy fruits (plantain).

  • Crop Choice and Diversification
    5 Crop choice and diversification Crop choice and diversification Bymolt, R., Laven, A., Tyszler, M. (2018). Demystifying the cocoa sector in Ghana and Côte d’Ivoire. Chapter 5, Crop choice and diversification. The Royal Tropical Institute (KIT). TITEL 71 Cocoa has sometimes been described as a ‘poor man’s crop’,1 as some recent studies have calculated that a large proportion of cocoa farmers live in extreme poverty. 2,3 Concerns increased with negative movements in world cocoa prices in the 2016/2017 season, and how this may negatively impact on the livelihoods of cocoa households. One narrative that has been gathering pace is that farmers should diversify further into other crop options. Proponents of this narrative suggest that diversification can help cocoa households mitigate risk from cocoa price fluctuations. Greater diversification with food crops is also considered to be useful for mitigating food insecurity and malnutrition, particularly outside of the main cocoa season.4 Some see diversification as a kind of insurance against climate change, which is expected to have at least some effect on producers in the coming decades.5,6 Others have suggested that increased diversification could also slow the worrying trend of deforestation and ‘bush clearing’ for cocoa.7 A final version of the diversification narrative is that diversified income from other crops can raise household incomes. In this view, population trends will lead to more demand for food and an associated increase in food prices.8 We caution that crop diversification is quickly becoming a new mantra, and yet the benefits of increased diversification for cocoa households is still under-researched.

Institute of Tropical Agriculture (IITA) is an autonomous, nonprofit corporation governed by a 15-member board of trustees headed by Dr. John J. McKelvey Jr. of the United States of Institute's America. The chief executive officer is Director General Dr. Ermond H. Hartmans. IITA seeks to develop alternatives to shifting cultivation that will maintain the productivity of the land under continuous cultivation in the humid and subhumid tropics; to develop higher yielding pest and disease resis­ tant varieties of cowpeas, yams and sweet potatoes worldwide, and of maize, rice, cassava and soybeans in Africa, and to strengthen national agricultural research systems by a comp'ehensive training program and collaborative research. IITA was established in 1967 by the Ford and Rockefeller Foundations, which provided the initial capital for buildings and development, and the Federal Military Government of Nigeria, who allotted 1,000 hectares of land for a headquarters site seven kilometers north of Ibadan. IITA is one of 13 nonprofit international agricultural research and training centers supported by the sultative Group for International Con­ Agricultural Research (CGIAR).
