Abstract

The study aimed to analyze the process of Landuse/Landcover change of two rural communes (Saé
Saboua and Chadakori) of Maradi region (Republic of Niger) over the past 28 years (1986 – 2014),
through landscape structure analysis by diachronic cartographic approach and landscape indices. Mixed
classification of temporal series of Landsat images led to identifying six Landuse/Landcover (LULC)
classes, namely ”cultivated land under shrubs and trees”, ”cultivated land under trees”, “continuous
cropland”, ”fallow/pasture land”, ”forest reserve”, and ”settlement”. The composition and structure of
the studied landscapes have greatly changed from 1986 to 2014. The class ”cultivated land under trees”
was the landscape matrix in 1986 with 38.65% of landscape total area but in 2001 and 2014 the class
”continuous cropland” became the landscape matrix. The changes also affected the ”forest reserve”
which was transformed to smallholder agricultural land from 1986 to 2014. The area occupied by
classes ”cultivated land under trees” changed from 38.65% in 1986 to 8.78% in 2014; and from 1986
to 2014, the area occupied by ”fallow/pasture land” has decreased of about 16%. The decrease in these
classes was in favor of ¨continuous crop land¨, ¨settlement¨ and “cultivated land under shrubs and trees”
which respectively gained 38%, 0.3% and 8.15% of their areas in 1986. The results of this study reflect
the problem of access to land and even land saturation in semi-arid region, a consequence of strong
population growth. They also contribute to a better rethinking of agricultural practices in order to initiate
adaptation and resilience strategies for the population facing food insecurity and poverty.
