Genetic erosion is a serious problem and computational models have been developed to prevent it. The computational modeling in this field not only includes (terrestrial) reserve design, but also decision modeling for related problems such as habitat restoration, marine reserve design, and nonreserve approaches to conservation management. Models have been formulated for evaluating tradeoffs between socioeconomic, biophysical, and spatial criteria in establishing marine reserves. The percolation theory and shortest path modeling have also been used. In this article we discuss the computational models that have been developed keeping in mind the sustainable developmentConservationists estimate that alarming rate at which biological species are disappearing will have an indelible impact on humanity. Targets which were set in 2002 to reduce the biodiversity loss by 2010 have not been met. The third global diversity outlook report said that loss of wildlife and habitats could not only exacerbate climate change through rising emissions but could also have a negative impact on food sources and industry.
