“…There are no accredited supply centers for planting materials in the country, and farmers rely on families, neighbors and open market for their supplies of planting materials, which may be coming from already infested fields. The constraints of taro blight disease to productivity of taro have been acknowledged in the West-African Sub Region [28,38,47]. The disease poses serious threats to global food security as well as economic hardship to the people in these taro producing regions of the world.…”

The success of the UN Sustainable Development Goals in reducing hunger and poverty is limited by crop losses. Globally, plant pests and diseases account for 40% yield losses which threatens food and nutrition security, livelihoods of citizenry and erode the resources of local and national economies. Phytophthora diseases are among the most important diseases in sub-Saharan Africa which result in severe socio-economic consequences. Roots and tubers and cash commodity crops are important staples and foreign exchange earner crops in Ghana which are significantly challenged by the incidence and severity of Phytophthora diseases. To ensure food availability, safeguard the local financial ecosystem and protect the environment, innovative and sound management practices are needed and this chapter reviews the different Phytophthora diseases on crops; more specifically with (cocoa and taro as case studies), the consequences and available management options that can be applied to manage the disease situation in Ghana.

“…In Ghana, apart from the three northern regions, taro production is mainly carried out in the southern part of the country. A few research works have been reported so far on Taro [47][48][49][50]. Even then, the focus had been on the profitability of the taro enterprise.…”

“…cassava and yam, few empirical studies have been conducted on cocoyam in Ghana. These studies, for instance Quaye et al [5] and Acheampong et al [7], however, did not focus specifically on the economics of cocoyam, while others were based only on data from experimental plots [12,13] and hence are probably not representative of the average cocoyam farmer.…”

Is there any economics in smallholder cocoyam production? Evidence from the forest agro-ecological zone of Ghana

et al. 2017

Background:Cocoyam is an important food security crop in Ghana because it stores better than all other root and tuber crops. Despite its socio-economic relevance, production has declined persistently since the last decade. This study attempts to examine the profitability of cocoyam production to smallholders in Ghana by estimating the returns on critical production resources. Using a multi-stage sampling technique, 150 cocoyam producers were randomly sampled across three major producing regions in Ghana.Results: Empirical results reveal that cocoyam production is generally not profitable given the present cost of capital in Ghana, suggesting why farmers are shifting from its production. A disaggregated analysis reveals that producers in Fanteakwa district have a competitive advantage over their counterparts in Asante Akyem South and Asunafo North districts in terms of relative profitability owing to higher yield and better produce price at terminal markets. Gross margin, net profit, and returns on assets, land as well as unpaid labour and management significantly varied across districts. Producing cocoyam on sole crop basis was found to significantly return higher than the predominant intercropping culture of production. Apart from production cost, gross margins, net income and returns to critical production factors under the mono-cropping system were found to be significantly higher, at 5% significance level, compared to the intercropping system. Conclusion:The study concludes that smallholder cocoyam production is presently not profitable, and hence, production scales have reduced to subsistence levels. Due to higher yield and better produce prices, Fanteakwa farmers have a competitive advantage over other producing districts. Production under the mono-cropping system is relatively profitable than under the intercropping system. However, the financial leverage of cocoyam production could be enhanced via policy alternatives directed at ensuring farmers' access to and intensification of productive inputs.
