This paper introduces Rapid Appraisal of Agricultural Innovation Systems (RAAIS). RAAIS is a diagnostic tool that can guide the analysis of complex agricultural problems and innovation capacity of the agricultural system in which the complex agricultural problem is embedded. RAAIS focuses on the integrated analysis of different dimensions of problems (e.g. biophysical, technological, socio-cultural, economic, institutional and political), interactions across different levels (e.g.
Parasitic weeds such as Striga spp and Rhamphicarpa fistulosa in smallholder rice production systems form an increasing problem for food and income security in sub-Saharan Africa. In this paper we implement the Rapid Appraisal of Agricultural Innovation Systems (RAAIS) as a diagnostic tool to identify specific and generic entry points for innovations to address parasitic weeds in rain-fed rice production in Tanzania. Data were gathered across three study sites in Tanzania where parasitic weeds are eminent (Kyela, Songea Rural and Morogoro Rural districts).
Every year, farmers in sub-Saharan Africa suffer from unacceptable levels of crop loss as a result of plant health problems, threatening their food security, income and livelihoods. This working paper shares lessons from Plantwise, an initiative to improve smallholder farmers’ access to plant health services in Uganda so that they can improve their yields, increase their incomes and improve their food security and livelihoods. The working paper presents lessons from almost ten years of experiences in implementing plant clinics in Uganda.
