Health for Animals Livelihood Improvement (HALI)

Health for Animals and Livelihood Improvement



Reducing Disease Risk at Human-Animal-Environment Interfaces in





HALI investigates the impact of zoonotic disease on the health and livelihoods of

rural Tanzanians living in the water-limited Ruaha ecosystem. HALI

simultaneously investigates the medical, ecological, socioeconomic, and policy

issues driving the system by carrying out assessments of wildlife for zoonotic

pathogens and disease, evaluating community members' perceptions about

disease impacts, introducing new diagnostic techniques, training community

members about zoonotic disease, monitoring water quality and availability,

assessing wildlife population-level risk factors for disease, and developing new

health and environmental policy interventions to mitigate the impacts of

zoonotic disease. In addition, HALI conducts wildlife disease surveillance at

critical wildlife-livestock-human interfaces throughout Tanzania as part of the

USAID Emerging Pandemic Threats program’s PREDICT project, and has

developed the first viral diagnostic laboratory for wildlife in Tanzania at the

Sokoine University of Agriculture.




HALI is a One Health focused collaborative US-Tanzania research and capacitybuilding

program aimed at assessing and addressing the effects of zoonotic

disease and water management on health and livelihoods throughout Tanzania,

with special emphasis on the Ruaha ecosystem.


Scope Local - Tanzania's Ruaha Ecosystem; Global – nation-wide wildlife disease

surveillance through the PREDICT project.


Primary Funders


From 2006-2009, HALI was sponsored by the Global Livestock CRSP, a

multidisciplinary collaborative research program funded by USAID. HALI is

currently funded through the USAID - PREDICT Project, the National

Institutes of Health, the US Fish and Wildlife Service's Wildlife Without

Borders Program, and the Adapting Livestock Systems to Climate Change




Participants & Key Collaborators


University of California - Davis Wildlife Health Center, University of California

- San Francisco, University of Vermont, Sokoine University of Agriculture,

Tanzania National Parks, Tanzania National Institute for Medical Research,

Tanzanian Wildlife Research Institute (TAWIRI), and the AHEAD Initiative.


Definition of One Health


The health of domestic animals, wildlife, and people is inextricably linked to the

ecosystem and natural resources on which all depend.


Monitoring & Evaluation Strategy


HALI’s monitoring and evaluation process is project dependent and determined

by funding agency requirements.
