Abstract

This research work assesses erosion risk and
soil loss in volcanic geomorphological landscape units from
Mololoa river basin, Mexico, by applying the universal soil
loss equation based on geographic information systems.
Natural resources of this Nayarita territorial region have
favored the economic development and establishment of
this state capital; however, such relationship, lacking an
environmental criterion planning, has caused their quick
deterioration, mainly in soils, which in time can result in
low levels of the territorial users’ well-being. According
to these results, 57,6 % geomorphological landscapes of
the studied area show very high and high erosion risk,
corresponding to “Sierras de San Juan” and “Volcan” units,
volcanic hill slopes associated with “Sangangüey” volcano
and “Tepeltitic” volcano slopes. In turn, 66 % of the studied
territory present some level of water erosion; 13,7 % of the
basin surface have significant soil losses by water erosion
(very high and high); 16,6 % show a moderate soil loss
whereas 35,7 % have lost less than 10 t ha-1 year-1.
