Livestock production in semi-arid grasslands is extremely vulnerable to climate change through altered water resource and
disease dynamics. These vulnerabilities impact livestock survival and marketability, household livelihoods and health,
and wildlife populations by enhancing zoonotic disease transmission pathways. Models that can integrate the interactions
between economic choices, resource availability, human and animal health, and climate change will provide an important
tool to evaluate adaptive policy and management strategies to climate change impacts. This research brief reports on
preliminary modeling efforts to connect climate change, hydrologic-based ecosystem services, and disease transmission as
part of a “one health” approach linking landscape management to broader public wellbeing and rural livelihood outcomes
