abstract = "Approximately 57 % of the Brazilian northeast region is recognized
as semi-arid land and has been undergoing intense land use
processes in the last decades, which have resulted in severe
degradation of its natural assets. Therefore, the objective of
this study is to identify the areas that are susceptible to
desertification in this region based on the 11 influencing factors
of desertification (pedology, geology, geomorphology, topography
data, land use and land cover change, aridity index, livestock
density, rural population density, fire hot spot density, human
development index, conservation units) which were simulated for
two different periods: 2000 and 2010. Each indicator were assigned
weights ranging from 1 to 2 (representing the best and the worst
conditions), representing classes indicating low, moderate and
high susceptibility to desertification. The results indicate that
94 % of the Brazilian northeast region is under moderate to high
susceptibility to desertification. The areas that were susceptible
to soil desertification increased by approximately 4.6 % (83.4
km2) from 2000 to 2010. The implementation of the methodology
provides the technical basis for decisionmaking that involves
mitigating actions and the first comprehensive national assessment
within the United Nations Convention to Combat Desertification
framework.",
