To get you started using the modelling software there are some example projects packaged with the modelling software and installed in the projects folder below your main application directory (default is C:\Program Files\SimSAGS4.1\Projects) . Each of these projects is a simulation scenario particular to the application of the model to each context, in these cases, sites in Kenya, Mongolia and Australia. Explore the data and look at some simulation output. What happens if you change a parameter?
Example 1 - Kenya
The welfare of Masai herders in the Kitengela Wildlife Dispersion Area is threatened by land use change; primarily, increased introduction of bomas and associated fences fragment tribal grazing land. There are also consequences for wildlife that utilize the area. Wildebeest travel through Kitengela to calving grounds in the south. It is envisaged that if there is sufficiently extensive boma development then the wildebeest migration may be blocked. Predictive modelling is being used to address these and other issues of primary concern for pastoralists in the region. Simulation scenarios can be constructed to include the suggested fragmentation of rangeland and migration routes.
  • 3 animal species: cattle, goats and wildebeest
  • 43-years of daily rainfall data
  • 30x30 model grid
  • generic perennial grass, shrub and tree plant types
Example 2 - Mongolia
There are an estimated 1.2 million gazelle in the Eastern Steppe. Rising unemployment has led to poverty and deteriorating livestock production systems, which in turn increase the pressure on natural resources, especially through wildlife poaching. Poachers illegally slaughter over 100,000 gazelles each year, threatening the steppe ecosystem and traditional culture. Since gazelles play a pivotal role in structuring the steppe's ecological landscape, ensuring their survival ensures sustainability of steppe biodiversity, ecological processes, and traditional culture.
  • 3 animal groups: cattle, sheep/goats and Mongolian gazelle
  • 38-years of daily rainfall data
  • 20x20 model grid)
  • Stipa grandis (perennial grass)
Example 3 - Australia
A paddock study in Queensland. The Burdekin Catchment discharges 22 million tons of sediment into the sea each year, a lot because of the Queensland cattle industry. This soil is swept onto the Great Barrier Reef where life is harmed by muddy waters blocking the sunlight. Modelling is helping to work out how much damage is being done by farming, and what can be done to make improvements to benefit the cattle, the farmers and the Great Barrier Reef.
  • 2 cattle herds, one in east and the other in west of paddock
  • 115-years of daily rainfall data
  • 21x21 model grid
  • generic perennial grass and tree plant types
Includes grid flat-file sequence generated using a Grid window which you can view, manipulate, animate and summarize using the Grid Viewer.
