Meru Animal Welfare Organization (MAWO) is a nonprofit animal-welfare organization working in Meru District. In 2010 MAWO undertook an initial baseline survey of the ten villages in the district to enhance the current animal welfare status in the area. The aim of this survey was to provide an empirical foundation for MAWO and to make strategic decisions involving the allocation of project resources and the design of the project components. The organization was established in order to address the five freedoms of the animals, of which most farmers in the area are not aware:
1. Freedom from hunger and thirst
2. Freedom from discomfort
3. Freedom from pain, injury and disease
4. Freedom from fear and distress
5. Freedom to express normal behavior  

The organization operates mainly in the Meru District Council in order to bring a lasting impact to the area before moving to other areas in Tanzania. The Headquarters are in USA River , Meru District, Arusha Region.
