The present study aims to analyze the spatial-temporal changes in the land use of rangelands and to model this dynamic. In this frame, Landsat ETM images from 1998, Landsat OLI 8 from 2008 and 2018 were used to map the land use units of the BMVO with QGis software. The CA_MARKOV model under IDRISI was used to model the spatial-temporal dynamics in 2035 and 2050. Dense forests, open forests and wooded savannas that have occupied 6.21% and 18.33% of the area in 1998, are gradually reduced to 1.06% and 0.28% in 2018. The areas of gallery forests (4.79%) and wooded and shrub savannas (16.01%) in 1998 decreased to occupy respectively 1.39% and 5.80% of area in 2018. Predictive modeling for 2035 and 2050 has shown that the BMVO rangelands will be dominated by urban areas; tree plantations and fields and fallows to the detriment of natural vegetation if current practices of natural resource use are maintained. Human pressures on natural resources combined with climate variability are the main causes of these landscape changes. The establishment of a new land use policy aimed at protecting the vegetation cover will allow this projection to be modified.</p>}, number={1}, journal={Sciences and Technologies for Substainable Agriculture}, author={HONVOU, Sèton Hanania Sylvanus and ABOH, André Boya and TEKA, Oscar and SEWADE, Clément and GANDONOU, Bernard Christophe and OUMOROU , Madjidou and SINSIN, Brice}, year={2022}, month={Apr.}, pages={18-29} }
