Livelihood Impacts & Economic Pressures

• Majority of emerging infectious diseases (EIDs) in people are of animal origin (zoonotic)

• 75% of emerging zoonoses have wildlife origins

• Annual population growth among highest in buffers to protected areas near wildlife

Why the Ruaha Ecosystem?

A Barabaig woman serves un-boiled milk to men

after she has finished milking and the men have

treated 2 sick cows.

Water Scarcity and

Resulting Threats:

• Livelihood impacts on pastoral

communities

• Labor stress

• Livestock productivity

• Human & livestock disease

• Impaired ecosystem services

• Water quality

• Disease transmission

• Impacts on wildlife and tourism

Strengthening Livestock Health, Human Nutrition,

and Pastoral Livelihoods in a Changing Climate

Formal and Informal Training

Men's and women’s disease risks likely differ; women

have regular, close contact with livestock, particularly

lactating females, whereas men have occasional, but

intense contact with sick animals.
