Variable General Info
Rainfall erosivity ?Comment:We used an equation for erosivity from Lenvain (1975), also used by the Indonesian Ministry of Forestry in sediment export modeling. This equation expresses erosivity as a function of monthly precipitation: Rm = 2.21*(Pm^1.36). Monthly precipitation data was obtained from the FAO GeoNetwork spatial data portal (http://www.fao.org/geonetwork/srv/en/main.home, “Global map of monthly precipitation - 10 arc minutes”), which provides monthly averages of precipitation and other climate variables from 1961 to 1990. The erosivity values obtained by this method were compared to those from an erosivity map of part of the landscape (Jambi province) obtained from a 2008 study by the Regional Development Planning Board of Jambi (unpublished), and were found to be in the same range. |
