Description:
Abstract:
Dataset combines a total of 8 variables to assess the
potential for land degradation in Belize. These variables
include; Soil pH, Shallow depth, Soil Fertility, Fire Risk,
Slope, Geology and Rainfall. Within these, the soil pH and
slope weigh heaviest. In general, those areas with a high
combined land degradation value should be considered
unsuitable for development, particularly agricultural development.
Purpose:
To maka first assessment of the potential for soil
degradation in Belize

Process_Description:
Wright et al. 1959. Soils map provided three base layers:
1) Soil pH: All acidic soils were given a value of 2
2) Soil depth: All skeletal soils were given a value of 1
3) Soil fertility: All soils with a fertility attribute
"low" or "very low" were given a value of 1
4) Meerman, J. C. 2004. Fire risk: All areas within a total
fire-risk class of 7 and higher were given a value of 1.
Note that Agricultural lands and "social fire risk" were
excluded from the total fire risk class since these types
of fire risk are not appropriate for the current purpose.
5) Meerman, J.C. 2004. Rainfall: All areas with a low
annual rainfall (drought risk) of 60-100' were given a
value of 1
6) Meerman, J.C. 2004. Rainfalll: All areas with a high
annual rainfall (leeching of nutrients) of 140-180' were
given a value of 1.
7) King et al 1992. Landsystems. All areas with slope
classes 4 or higher (erosion risk) were given a value of 2.
8) Cornec: Geology. All areas with a creataceous/limestone
geology (drought stress) were given a value of 1.
Ultimately, all attribute values were added up to give a
total land degradation risk value ranging potentially from
0-10 (no values higher than 7 were reached due to the fact
that some of the attributes were mutually exclusive. While
there is a risk for land degradation for all areas, only
those areas with a value of 5 or higher should be
considered at danger under the present conditions.
April 5, 2006: In order to reduce file size, contribution
data (used for calculation of total land degradation
potential removed and equal value polygons merged.
Otherwise no changes made.
