Executive summary

Tanzania is prone to refugee influxes, often of long duration. Despite facing its own economic challenges, for decades Tanzania has welcomed thousands of refugees fleeing conflicts in neighboring countries of Great Lakes Region. The counties geographic proximity to the strifetorn Congo Basin is responsible in part for the ease access of displaced populations. As well Tanzania was an early signatory in the region to international agreements on the rights and welfare of refugee and asylum seekers As of December, 2018, Tanzania host some 284,300 camp-based refugees, 77% of who are children and woman, in Nduta, Nyarugusu and Mtendeli Refugee Camps in Kigoma region in Northwest Tanzania. About 74% are from Burundi, and the remaining 26% are primarily from Democratic republic of Congo.
Following a Tripartite Commission meeting in August 2017, the governments of Tanzania,
Burundi, and UNHCR agreed to assist refugees who wish to voluntarily repatriate from Tanzania to Burundi. A subsequent meeting in March 2018 reaffirmed the commitment of both governments and UNHCR to uphold the principle of voluntariness, and noted that while some refugees may opt to return, others will continue to be in need of international protection. The March 2018 Tripartite meeting also produced a work plan entailing the repatriation of approximately 2,000 refugees per week from 5 April to 31 December 2018. As from January to 30th September 2018, a total of 52,260 refugees were assisted to voluntarily repatriate to Burundi from Tanzania in 88 Convoys; bringing the total repatriated from September 2017 to 57,865 of which 57.2% are children.

The surveys were conducted using the UNHCR Standardised Expanded Nutrition Survey (SENS) version 2 (2013), and the Standardised Monitoring and Assessments of Relief and Transitions (SMART) guidelines Two stage cluster sampling was used to identify the survey respondents, the first stage involved identifying clusters and the second stage was to identify the households. The Emergency Nutrition Assessment (ENA) software version July 9th, 2015 which uses Probability Proportion to Sample Size (PPS) was used to calculate the sample size and to select the clusters. To select households for participation in the survey from the clusters, Simple random sampling was used. The parameters that were used to calculate the sample size are summarized in Table 3 .
The survey had a total of 6 modules, 3 individual level questionnaires and 3 household level questionnaires. The modules are;

• Anthropometry and health; targeting all children (6 to 59 months) in all the sampled households;

• Infant and Young Child Feeding (IYCF); targeting all children 0 to 23 months in all the sampled households • Anaemia; targeting all children 6 to 59 months and all non-pregnant women 15 to 49 years in every other sampled households;

• Food security; targeting every other sample households • Water, Sanitation and Hygiene (WASH); targeting all the sampled households.

• Mosquito net coverage; targeting every other sampled households;
