Cultivation Intensity

Friday, January 12th, 2007

MatthewsDifficult to find any raster data set about “Land Use Intensity” or “Agricultural Intensity”. It seems the only existing one is Matthews Cultivation Intensity data set from 1984.

The Matthews Vegetation data set comes from a global map of vegetation types, which was compiled from up to 100 existing map sources at the Goddard Institute of Space Studies (GISS), Columbia University, in New York. It shows the predominant vegetation type (one out of 32 classes) within each one degree-square latitude/longitude grid cell. Matthews Cultivation Intensity data set is based on existing maps of vegetation and satellite imagery, and it shows the percentage of each one-degree square latitude/longitude grid cell that is under cultivation, versus the percentage of natural vegetation, including five classes.

Let me know if you are interested in it.

Emission to DamageNice slide out of Shanna’s PPT presentation. Just a reminder for myself. You all know it well, but I need to look at it on a regular basis so I learn to know what you guys are talking about… :-)

Atlas of the BiosphereThere are some interesting data sets on this site, not too actual in most cases, but nevertheless eventually useful, as for example: another data set on “Built-up land”, “Irrigated Lands”,?Ã?¬â?  some more soil data, “Suitability for Agriculture” and others.

Please let me know which data we should include.
