    ECONOMICS OF SMALL-SCALE SEED YAM PRODUCTION IN GHANA: IMPLICATIONS FOR COMMERCIALIZATION
    (Journal of Sustainable Development in Africa, 2011) Aidoo Robert; Nimoh Fred; Bakang John-Eudes Andivi; Ohene-Yankyera Kwasi; Fialor Simon Cudjoe; Abaidoo R. C
    This study evaluated the economics of seed yam production in four major yam producing Districts in Ghana. The analysis was based on primary data collected from seventy (70) seed yam producers selected through snowball sampling technique. The data covered seed yam production activities during the 2009 cropping season. Descriptive statistics were used to summarize the data and gross margin analysis was used to assess the profitability of seed yam production. On average, a typical seed yam producer cultivated 4.5 acres (1.8 ha) of seed yam and the yield was estimated at 8,319setts/acre. Average variable cost incurred on an acre of seed yam farm was estimated at GH¢685.68 and planting material costs constituted about 44% of this cost. The gross revenue obtained from seed yam sales was estimated at GH¢1,518.22 per acre and the corresponding gross margin was found to be GH¢832.54 per acre. Evidence from the study suggests that seed yam production is a profitable venture. However, the gross margin of seed yam production varied markedly across yam producing Districts, primarily due to differences in yield and price of seed yams. The two most important production constraints were identified to be inadequate capital and high labour cost. The paper has demonstrated that seed yam production has bright prospects in Ghana and presents an opportunity for private investors to diversify their investment portfolios.

    Estimation of Margins and Efficiency in the Ghanaian Yam Marketing Chain
    (: Asian Economic and Social Society, 2012) Aidoo R.; Nimoh Fred; Bakang John-Eudes Andivi; Ohene-Yankyera Kwasi; Fialor Simon Cudjoe; Osei Mensah James; Abaidoo R. C
    The main objective of the paper was to examine the costs, returns and efficiency levels obtained by key players in the Ghanaian yam marketing chain. A total of 320 players/actors (farmers, wholesalers, retailers and cross-border traders) in the Ghanaian yam industry were selected from four districts (Techiman, Atebubu, Ejura-Sekyedumasi and Nkwanta) through a multi-stage sampling approach for the study. In addition to descriptive statistics, gross margin, net margin and marketing efficiency analyses were performed using the field data. There was a long chain of greater than three channels through which yams moved from the producer to the final consumer. Yam marketing was found to be a profitable venture for all the key players in the yam marketing chain. Net marketing margin of about GH¢15.52 (US$9.13) was obtained when the farmer himself sold 100tubers of yams in the market rather than at the farm gate. The net marketing margin obtained by wholesalers was estimated at GH¢27.39 per 100tubers of yam sold, which was equivalent to about 61% of the gross margin obtained. Net marketing margin for retailers was estimated at GH¢15.37, representing 61% of the gross margin obtained. A net marketing margin of GH¢33.91 was obtained for every 100tubers of yam transported across Ghana’s borders by cross-border traders. Generally, the study found out that net marketing margin was highest for cross-border yam traders, followed by wholesalers. Yam marketing activities among retailers, wholesalers and cross border traders were found to be highly efficient with efficiency ratios in excess of 100%. However, yam marketing among producer-sellers was found to be inefficient with efficiency ratio of about 86%.The study recommended policies and strategies to be adopted by central and local government authorities to address key constraints such as poor road network, limited financial resources, poor storage facilities and high cost of transportation that serve as impediments to the efficiency of the yam marketing system in Ghana.

    Health Risk Perception on Excreta Reuse for Peri-urban Agriculture in Southern Ghana
    (core, 2014) Nimoh Fred; Ohene-Yankyera Kwasi; Poku Kofi; Konradsen Flemming; Abaidoo R. C
    Access to proper sanitation and disposal sites for faecal sludge is problematic in Ghana, particularly in peri urban communities. Using a cross-sectional household-level survey data, this study investigates farmers’ perceptions on the health risks of excreta reuse for peri-urban agriculture in Shai-Osudoku district in Ghana. It was found that a majority of the farmers ‘disagree’ that excreta are a waste and are willing to use excreta as fertilizer, albeit a majority ‘agreeing’ perception that excreta reuse can pose health risks. Empirical results from an ordered probit model show that the decision to use excreta as fertilizer is more related to perceptions on excreta as a resource rather than personal and farm characteristics. However, there is some relationship between personal and farm characteristics and perceptions on the health risks of excreta reuse for agricultural purpose. There is also a strong relationship between the perception that excreta are a waste and perceptions on the health risks of excreta reuse. Programmes aimed at promoting improved sanitation should consider the reuse potential of excreta in agriculture, as attested by the farmers as a resource for crop production. There is the need to educate farmers on how excreta could properly be handled and used in agriculture. Other policy options toward risk reducing strategies that involve relevant government institutions and the local media should also be considered to avoid any health hazards associated with excreta reuse in agriculture

    Households’ Latrine Preference and Financing Mechanisms in Peri-urban Ghana
    (Academia, 2014) Nimoh Fred; Poku Kofi; Ohene-Yankyera Kwasi; Konradsen Flemming; Abaidoo R. C
    Using household-level survey data, this study investigates households’ latrine preference and financing mechanisms for improved latrines in the Ningo-Prampram district in the Greater Accra region of Ghana. Descriptive and inferential analyses are employed for data analysis and reporting. The results of the study show that a majority of the sampled households practice open defecation due to lack of funds and space for an improved latrine. Most of the households prefer the flush/pour-flush to the piped sewer system latrine or the ventilated improved pit (VIP) latrine. About half of the households prefer to use own funds via savings or ‘susu’ to build their latrines, and very few prefer funds from the financial institutions (FIs), albeit the FIs are interested in providing loans for household latrines. Empirical results from a binary logistic model show that there is some relationship between households’ latrine financing decisions and their socioeconomic and community characteristics, such as gender, education, household composition, income, tenancy, type of defecating practiced and type of community. The study recommends the need to educate households to consider ‘cheaper’ and more feasible latrine technologies, and also adopt joint-resource mobilization strategies for their latrines. There is also the need to educate the households on the possibility and conditions for alternative sources of funds for improved latrines. Policy efforts by the government and other stakeholders toward a sustainable uptake of improved sanitation should also consider the household and community factors that may influence a household’s latrine preference and financing decision.
