Child rights abuse has become a serious global concern in the 21st century as it has been reflected in the global agenda of SDGs. Tanzania like other developing countries experienced significant child rights abuse in the 1990s due to the influx of the number of orphans and vulnerable children (OVC) which was highly influenced by the HIV and AIDS pandemic, poverty, urbanization, etc. OVC was exposed to the high risk of being deprived of their rights following the failure of the formal systems and the shortage of childcare workforce that necessitated the government to involve the key child welfare stakeholders to revitalize and capacitate among the Ujamaa Intersections Models (UIM) under Ubuntu philosophy. Ultimate the country successfully designed an Indigenous cadre of para-social work (PSW) that advocated for and addressed the multiple rights of vulnerable children from 2007. Initiation and operation of PSW are embedded in the Ujamaa sections from side to side with social work and Ubuntu competence, this combination capacitated existing Ujamaa Intersections in the community such as family, extended families, neighborhood, local leadership, ecology, spirituality, and wider attributes in realizing child rights. The relevance of Ubuntu values and social work enabled para-social workers to identify the special needs of vulnerable children, increase community child protection awareness, create alarm systems for abused children, and sometimes link them to temporary self-shelters or social welfare services, etc. Despite the challenges, PSW succeeded in advocating for children's rights and improved the quality of life of children and their families. PSW has rendered evidence based on how the Indigenous models can offer relevant and sustainable solutions in addressing the rights of vulnerable populations in the community. Over time, several African countries adopted the PSW model and the model calls for child rights stakeholders and global decision-makers to revisit and relearn the capacity of the PSW model in the realization of SDG including protecting children from abuse, exploitation, trafficking, and violence. Also, it has relevant sustainable opportunities that ensure children attain inclusive and equitable quality social welfare services.
