Food security is one of the main goals of rural poor people. To enhance food security in this context, participatory action research can help to ensure sustained success while considering entire food value chains (FVC). This paper assesses the feasibility and potential success of upgrading strategies (UPS) as well as their assessment criteria as developed by German and Tanzanian agricultural scientists. The results form part of a larger participatory research project conducted in two climatically representative regions of Tanzania: semi-arid Dodoma and subhumid Morogoro. This paper presents the findings with respect to food processing, waste management and bioenergy, along with income generation and market participation. Assessments on other components of the FVC, including natural resource management, crop production and consumption, are reported by Graef et al (2015). The assessments for food processing revealed preferences for preservation techniques, oil extraction processes and food storage devices for the semi-arid region. In contrast, in the subhumid region, the experts favoured food storage devices and preservation techniques. Assessments of waste management and bioenergy UPS for both regions indicated the importance of animal feed from crop residues, crop residues as mulch and compost from food waste, although with somewhat different priorities. Assessments on income generation and markets in both regions revealed preferences for savings and credit cooperatives and communication techniques, but also indicated that warehouse receipt systems and guarantee systems had a high impact. Assessments differed between the two different climatic regions, and to some extent also between the nationality of experts and their gender. The authors therefore attach importance to integrating different South–North and female–male awareness in assessments among scientists. Moreover, local and/or regional stakeholders and experts should be involved in developing site-adapted UPS for enhancing FVCs.
ScalA-FS: expert-based ex-ante assessments of local requirements and success potential of upgrading strategies for improving food security in rural Tanzania

Enhancing food security is the main goal of subsistence farmers, who are vulnerable to food insecurity in sub-Saharan Africa. Participatory research across food value chains (FVC) can help stabilize and enhance food security by developing upgrading strategies (UPS). However, prior to successful widespread adoption and geographical upscaling, such practices need in-depth understanding of their suitability in target areas and their particular local requirements. Ex-ante assessments of selected UPS were carried out by German and Tanzanian agricultural scientists using the BScalA-FS^ tool. The participating experts included those responsible for implementation. The tool aims to systematically evaluate, at the community level, UPS that have been successfully implemented elsewhere, evaluate their potential for dissemination, and identify entry points for adjustments during implementation. Assessment indicators were developed through a participatory process. UPS relate to a) natural resource management and crop production; b) food processing and bioenergy; c) income generation and market participation; and d) food consumption. Here we present the ScalA-FS assessment results on UPS suitability as well as on its implementation requirements. We focused on the local context needed to enable a productive collaboration between smallholder farmers and implementing research and/or development organizations. Implementation requirements for the selected UPS were assessed as generally low to medium, and projected suitability in most cases was high. Local knowledge and education (human capital) along with visible success after a short time were important criteria of success of UPS. Here, careful consideration of the challenges before and after implementation of UPS is suggested. ScalA-FS should be applied early in the implementation process of UPS in order to support adaptations and successful upscaling at other locations.
