Abstract

Purpose

Cassava production surged noticeably in Southeastern Africa beginning in the 1990s. The purpose of this paper is to examine the commercial responses and food security consequences of cassava production growth in the region.

Design/methodology/approach

The paper incorporates a mix of quantitative analysis, based primarily on original analysis of national farm household survey data, together with key informant interviews with value chain participants in the three neighboring countries of Malawi, Mozambique and Zambia.

Findings

In the cassava production zones, cassava's high productivity translates into per kilogram carbohydrate costs 60 per cent to 70 per cent of the cost of cereals such as maize and wheat, thereby opening up a range of profitable opportunities for commercialization of cassava‐based foods, feeds and industrial products. Despite this potential, cassava commercialization in Southeastern Africa remains in its formative stages, with only 10 per cent to 30 per cent of production currently marketed. Unlike West Africa, where cassava commercialization has centered on marketing prepared cassava‐based convenience foods, the emerging cassava markets in Southeastern Africa have centered on fresh cassava, low value‐added cassava flour, and experiments in industrial processing of cassava‐based starches, biofuels and feeds. Strategic investment in a set of key public goods (breeding, training in food sciences and food safety, and research on in‐ground cassava storage) can help to shape this transition in ways that benefit both commercial interests and the food security of vulnerable households.

Originality/value

The paper compares cassava commercialization across differing agro‐climatic zones, policy environments and food staple zones.

Abstract

The choice of subject for a credit paper to pass a university course in food toxicology was analysed as a measure of the curiosity towards different topics. The investigation covers 575 students over 28 years. The choices were analysed against investigations on food safety concerns, the development in the period, the official risk communication campaigns and media detailed scandals. Food additives (131 papers) followed by plant toxins were the most popular subjects, with artificial sweeteners as the most attractive within the additives. Pesticides were only chosen by 21 students, residues of veterinary drugs being even less attractive. To a certain extent choices differed among the two genders. The article proposes a theoretical device “the common basic level of specific curiosity”. This is fairly stable over time, and specific in that the curiosity towards subgroups within the additives differ. These findings should be taken into account when planning risk communication.
