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.

In 1989, the Asian Development Bank provided technical assistance to the then Department of Agriculture and the Survey Department through a NZ Consulting Firm - ANZDEC under an ADB Land Resource Planning Survey Project. The Project provided training on mapping and GIS capability for the survey staff who were involved in the mapping work. Electronic GIS data and equipment were handed over to the Department of Agriculture at the end of the project which were later on damaged by Cyclone Ofa in 1990. A decade later, the Integrated Climate Change Risks in Agriculture and Health Sectors (ICCRAHSS) Project funded by the GEF through UNDP contracted the services of a consultant to provide: -improved GIS maps for soil, crops and rainfall distribution under different climatic projections; -review existing GIS systems and possible areas for collaboration; -consider a program to support capacity building on the use of the system and; -some applications that addresses options for climate change adaptation for the agriculture sector. Based on this report, a GIS system for the Ministry of Agriculture was procured to address the need for such a system to be in place with the expectation that the system will be properly utilized and maintained by relevant people.
