Abstract

An impact assessment of food-securing upgrading strategies (UPS) can be performed to assess actual and potential UPS effects at the local level. We developed an assessment framework that integrates the main components of the food value chain (FVC), including natural resources, food production, processing, marketing, and consumption. The framework provides a generic template in which different impact assessment approaches can be complementarily integrated and was tested for a case study in Tanzania. The framework employs a structured sequence of steps: (1) context analysis and the development of UPS, (2) the selection and application of assessment approaches and (3) the establishment of food security criteria and UPS effects. To illustrate the flexibility and use of the framework, the inputs of three different impact assessment approaches were considered. First, data from a household survey was applied to provide baseline information at the local level. Second, scientific knowledge was employed to systematically assess the selected UPS. Third, local stakeholder knowledge was considered to identify the local food security constraints and preferences and provide assessments of potential UPS effects. The Framework for Participatory Impact Assessment (FoPIA) approach was utilized to conduct local focus group discussions, and the Scaling Up Assessment Tool for Food Security (ScalA-FS) was employed to gather scientific knowledge about specific UPS impacts. Based on the preliminary results from the framework testing, diverse stakeholder participation was found to be essential for considering local preferences and to engage stakeholders in the assessment process, whereas scientific knowledge and monitoring data were needed to complement the “local picture” with more quantifiable results. The strengths and shortcomings of the framework are discussed.
