Different typologies of Urban Sprawl ….
Avignon Madrid
Urban Scattered development
Urban Compact development
Shape of the urban growth
Monitoring global and local land transformations
Our main question : In which way urban growth shape influences farmland loss?
There are a lot of publications on farmland loss due to urban growth
Not enough publications on the correlation between urban growth shape and farmland loss.
We will use the landscape metrics with fragstat
Beyond Avignon and Madrid, our objective is to build a model assessing the effect on farmland of each shape of urbangrowth
