Land change modeling

Land change modeling is like a game where you can imagine what a place - like a city, or a piece of countryside - could look like in the future. You start by drawing a picture of what the place looks like today. Then you decide what changes might happen and draw those changes on your picture. For example, you could add in roads, buildings, or parks. Finally, you use math to figure out how the changes you drew might affect things like water and air pollution. This helps people make decisions about what changes might be good for the environment.
