Description In this study, historical landscape dynamics were investigated to (i) map the land
use/cover types for the years 1972, 1987, 2000 and 2014; (ii) determine the types and processes
of landscape dynamics; and (iii) assess the landscape fragmentation and habitat loss
over time. Supervised classification of multi-temporal Landsat images was used through a
pixel-based approach. Post–classification methods included systematic and random change
detection, trajectories analysis and landscape fragmentation assessment. The overall accuracies
(and Kappa statistics) were of 68.86% (0.63), 91.32% (0.79), 90.66% (0.88) and
91.88% (0.89) for 1972, 1987, 2000 and 2014, respectively. The spatio-temporal analyses
indicated that forests, woodlands and savannahs dominated the landscapes during the four
dates, though constant areal decreases were observed. The most important dynamic process
was the decline of woodlands with an average annual net loss rate of –2%. Meanwhile, the
most important land transformation occurred during the transition 2000–2014, due to anthropogenic
pressures. Though the most important loss of vegetation greenness occurred in
the unprotected areas, the overall analyses of change indicated a declining trend of land
cover quality and an increasing landscape fragmentation. Sustainable conservation strategies
should be promoted while focusing restoration attention on degraded lands and fragmented
ecosystems in order to support rural livelihood and biodiversity conservation
