In April 2021, JMKF collaborated with the Ministry of Health (MoH) and the National Institute for Medical Research (NIMR), to map interventions that addressed maternal and newborn deaths in Tanzania mainland from January 2016 to June 2021. Coverage of data collected is from 184 local councils across the 26 regions with information on the type of interventions, coverage of the interventions, highlighting innovations, key actors, main gaps, and opportunities for scaling up those interventions for Tanzania to reach the related 2030 SDG targets. The report will be used to foster collaboration and support the efforts of the government and other MNCH stakeholders to improve MNCH services by ensuring the survival of all women and newborns during pregnancy, labour and delivery, and the postpartum period.
