What are the advantages and disadvantages of regional statistics like FAOSTAT?
It shows the totals per land use types for several time steps and can be used to distinguish increases or decreases.
Advantages are:
standard software (spreadsheet)
simple and fast
Disadvantages are:
not spatially explicit
no information on transitions -
How do you do a transition analysis in GIS(or excel)
10*valueyear1+valueyear2=valuetransition -
What is the goal of making a transition matrix?
Focus on transitions rather than totals
results per grid cell rather than per land use types -
What are the advantages and disadvantages of a transtion matrix?
Advantages:
shows spatially explicit changes (maps!)
describes actual transition between types of use
disadvantages:
Gis knowledge and software needed
data intensive -

How much population growth in West africa since 1950?
Quintupled -
The research area was divided in 6 sub regions, what was this based on?
The division was based on the mean annual precipitation. -
Did the paper state a clear correlation between rates of land cover change and population densities?
Yes it did.
The regression explained 57% of the variability at a p value of 0.12 for 1975-2000 and 83% with p value of 0.02 for 2000-2013 -
What are the years the paper of west africa examined?
1975, 2000, 2013 -
Did the paper state a clear correlation between rates of land cover change and precipatation?
It did not state a significant correlation -
The paper made use of different metrics to measure the landcover change, name them
Magnitude (size)
intensity (rate)
