Journal of Food Sec. (2017) 9:pp. 1299–1308Tanzania is the second largest country in East Africa with about 50 million inhabitants in 2014, and it is also considered as one of the poorest countries in the world. The country strongly depends on agriculture production. Like many other poor countries in sub-Saharan Africa, Tanzania sees food security as a central part of development and poverty reduction efforts. This work aims to investigate the opportunities and constraints of implementing a policy of BKitchen Gardens^ as a practice for two regions of Tanzania. The research was carried out with a qualitative approach through a first round of semi-structured interviews using a Scaling up Assessment Tool (ScalA), and a second round with a questionnaire survey, using a Scaling up Assessment Tool for Food Security (ScalA-FS) by Tanzanian and German experts from the Trans-SEC project. The experts assessed implementation suitability and the institutional requirements of Kitchen Garden across the food value chains in two Tanzanian regions with different climate regions, namely Dodoma (semi-arid) and Morogoro (sub-humid). Kitchen Garden assessments did not differ significantly between these regions. The ScalA tools provided a range of statements that allowed an overview of the structural situation to be obtained, which could enable Kitchen Garden activity to be incentivized and scaled up. However, a number of specific aspects, potentials, challenges, and likely bottlenecks of implementation related to their feasibility and institutional requirements, were indicated, which should be carefully monitored during implementation. Adopting the recommended strategies could help to close gaps in implementation, enhance community empowerment and social network development, reduce food insecurity and improve the health of the communities.
