Many neglected tropical zoonotic pathogens are maintained by introduced mammals, and on islands the most common introduced species are rodents, cats, and dogs. Management of introduced mammals, including control or eradication of feral populations, which is frequently done for ecological restoration, could also reduce or eliminate the pathogens these animals carry. Understanding the burden of these zoonotic diseases is crucial for quantifying the potential public health benefits of introduced mammal management. However, epidemiological data are only available from a small subset of islands where these introduced mammals co-occur with people. We examined socioeconomic and climatic variables as predictors for disease burdens of angiostrongyliasis, leptospirosis, toxoplasmosis, toxocariasis, and rabies from 57 islands or island countries. We found strong correlates of disease burden for leptospirosis, Toxoplasma gondii infection, angiostrongyliasis, and toxocariasis with more than 50% of the variance explained, and an average of 57% (range = 32–95%) predictive accuracy on out-of-sample data. We used these relationships to provide estimates of leptospirosis incidence and T. gondii seroprevalence infection on islands where nonnative rodents and cats are present. These predicted estimates of disease burden could be used in an initial assessment of whether the costs of managing introduced mammal reservoirs might be less than the costs of perpetual treatment of these diseases on islands.

2016
The 2016 State of Environment (SOE) Report for the Republic of Marshall Islands (RMI) updates the 1992 SOE report. It uses the DPSIR model (Drivers, Pressures, State, Impact and Response) and aims to:| Document the key drivers and pressures behind the changing environment.| Assess the RMI environment since 1992, using the best available information on the state of RMI’s environment in seven key themes: Atmosphere and Climate, Land, Marine, Biodiversity, Culture and Heritage, Built Environment and Nuclear Legacy.| Document the impacts of environmental changes on the society, economy and environment from changes in the state of the environment.| Document current responses to protect and better manage RMI’s natural resources.| Provide recommendations for RMI to address key challenges and link them to actions in the National Environmental Management Strategy (NEMS) and other key policy documents. This report is comprised of three discussions: 1. Drivers and Pressures in Marshall Islands: A summary of the main points discussed in the Pressures and Drivers section of the report. 2.The State of RMI’s Environment and Impacts on the Society, Economy and Environment: Key findings for each of the seven themes. 3. Responses and Recommendations – Challenges in Moving from Policy to Action: This presents key responses, opportunities, challenges and recommendations.
