Various non-governmental organizations (NGOs) and United Nations agencies are working to reduce disparities in Tanzania, one of the poorest countries in East Africa. They are focusing on improving health, education, food production, infrastructure, water access, and other areas. For example, the Red Cross has vaccinated over 14 million children, saving lives, and UNICEF helps build and improve schools. These efforts aim to boost living standards and quality of life in Tanzania over the long run. However, some issues with aid include projects not being sustainable once funding ends and communities becoming too reliant on outside aid.
