The aim of this study was to investigate the sustainability performance in supply chain of dairy products in Tanzania. The study conducted in Simanjiro district using cross-sectional survey method and focus group discussions. The findings of this study show that processing facilities, access to market, storage facilities, distribution and delivery system are the main enormous supply chain constraints which affect the sustainability performance of diary sector. This study recommends that in order to ensure sustainable performance of dairy sector, a multidisciplinary approach, value chain techniques, diverse strategies and dialogues should be taken involving all key actors (i.e. LGA's, civil society, respective ministries, smallholders' farmers, processing firms, and dairy entrepreneurs).

The purpose of this paper is to deliver a structured literature review of poultry meat supply chain (PMSC) in EAC and provide a platform for practitioners and researchers trying to identify the existing state of work, gaps in current research, and future directions. An in-depth analysis was carried out to determine the vital information from the literature. This paper has identified gaps to be explored about PMSC, which may be used by researchers to enrich theory construction, and practitioners may concentrate on establishing the extent and frontiers of the agro-supply chain. This research work is an attempt to make a critical literature review of available literature on agro SCM practices for developing countries. The research articles and other documents related to the PMSC were collected from online databases like Google Scholar, Scopus, and EBSCO for ten years (2010-2020). Findings and conclusion are provided based on the literature reviewed. Finally, the recommendations are provided for the development of the poultry sector in the region and the direction for future research.
