Hi roedogg,
Here you go -
1) Cropland
2) Grazing land
3) Forest
4) Fishing grounds
5) Energy
Ecological footprint:
"Abbreviated to eco-footprint or just footprint. Defined by the WWF,
"an ecological footprint compares countries' consumption of natural
resources with the Earth's biological capacity to regenerate them," or
"a measure of humanity's use of renewable resources."
Footprint, national:
"A country's eco-footprint is the total area needed (inside or outside
its own territory) to produce the renewable natural resources it
consumes, including those used to sustain energy, and those used for
infrastructure. This area is expressed in a theoretical measurement
called global hectares of productivity. For example, the UK [LPR 2002]
has a total footprint of 5.35 global hectares per person, while
Bulgaria's footprint is only 1.84 gha per person. The total footprint
is made up of five constituent footprints: for cropland, grazing land,
forest, fishing grounds and energy . When these constituents have been
taken into account, extra is added for water withdrawals,
infrastructure and, in OPT's case, another 12 per cent land allocation
is made to allow for wilderness (all other territory being already
used to fill one of the five constituent footprint purposes - such as
forest for forest products)."

I hope this helps. If you have any questions, please post a
clarification request *before* closing/rating my answer and I'll be
happy to reply.
Thank you,
