On the road to potato processing in African tropical highlands.

Abstract

Potato processing at the industrial level is relatively insignificant in the tropical highlands of Africa in Ethiopia, Kenya, Uganda and Rwanda. No large international companies are present in this area whereas they have successfully established themselves in North Africa (Egypt) and South Africa. The reason for the presence of large French fries (chips) and crisps factories in northern and southern Africa is the availability of growers who have relatively large areas of irrigated land assuring a year-round flow of raw material with the required specification and consistency for the finished product. The objectives of recently carried out investigations in Rwanda and Ethiopia funded by The Netherlands government were to investigate the challenges and opportunities for the establishment of (private) industrial processing facilities. Such factories and installations would create added value through employment in the whole supply chain from breeding new varieties, creating a supply chain of seed and ware (raw material) potatoes, postharvest handling, processing and trade. The study in Rwanda and Ethiopia consisted of the following elements: (i) a quick scan of potato production related to the potential supply of raw material to the industry; (ii) an inventory of current processing at household and restaurant level such as boiling, mashing, and the preparation of French fries and crisps; and (iii) an inventory of processed potato products such as frozen French fries, crisps and mashed potato powder and packed fresh tubers in markets and supermarkets. An estimate was then made of the current and future market for these products. The type of small- and medium-sized equipment needed and their costs was assessed. Historical meteorological data and a crop growth model that calculated attainable yields and water use in the two countries were used for yield gap analyses. From this and from farm surveys the costs and competitiveness of the raw material were derived and from it conclusions regarding the costs of locally produced versus imported finished products. We concluded that the farm-gate potato price, which is related to the cost of production, is quite competitive - in Ethiopia it is about half that of northern Europe and in Rwanda it is about equal to north-western Europe - which is most important in order to be competitive with imports in the future. An investor planned a frozen French fry (chips) factory in Ethiopia to open in 2014. In Rwanda a similar action is planned with government involvement.

A review of varietal change in roots, tubers and bananas: consumer preferences and other drivers of adoption and implications for breeding

“…Regarding gender differences in the adoption of varieties, there is a single reference in Walker & Alwang (2015: 178) related to the preference of semi‐subsistence producers, and especially women growers, for the Cruza 148 potato variety. This preference was due to Cruza 148’s tolerance to bacterial wilt and late blight, very short dormancy and high yields under most conditions, despite the fact that traders and consumers tended to discount this variety because of a blue ring in its flesh (Haverkort et al ., 2015; Labarta, 2015).…”

Translating Ethiopian potato seed networks: identifying strategic intervention points for managing bacterial wilt and other diseases

“…Farmers often obtain knowledge regarding seed quality and management practices informally as well. One step toward ensuring the food and income security of smallholders in the potato farming systems could be greater involvement of key system stakeholders to support the quality and health of seed potato (Beyene, 2010;Carvajal-Yepes et al, 2019;Damtew et al, 2018;Haverkort et al, 2012).…”

Crop switching as an adaptation strategy to climate change: the case of Semien Shewa Zone of Ethiopia

“…Besides its market advantages, the crop possesses favorable characteristics of short growing period and suitability for semiarid climate (Beshah, 2015). Similarly, potato is one of the fastest expanding crops in the country owing to its nutritional advantage, increasing local demand and short growing season (Emana and Nigussie, 2011; Haverkort et al , 2012).…”
