Abstract
The deforestation is a major problem in Côte d’Ivoire. Monogaga protected forest is strongly cleared for agriculture. Thus, the research aims to determine the influence of the farmer’s occupancies on the forest dynamic. The supervised classification by Neural net has been applied with success to Landsat imagery of 1986 and 2017. It has been preceded by the vegetation physiognomic characterization. The vegetation units are the closed forest, the degraded forest and the fallow-crops. The neural Net classification has been used to discriminate the closed forest area. To the dynamic level, the loss of closed forest proportion between 1986 and 2017 is 86.52%. The annual deforestation rate in regular (linear) and irregular (exponential) level is respectively 2.88% and 6.46% on 30 years. The anthropogenic units descended of the degradation represent some more 90 % of land cover, with a contribution of the crops at more than 40%. These same units are also implied in regeneration to a proportion of some more 90%, always with the crops proportion of 60%. Several mutations are in use. It’s the degradation, conservation and regeneration, with a predominance of degradation. The result shows the bad conservation. This survey showed that the protected forest is submitted to agricultural pressure and all other anthropogenic activities. It is important to have a forest conservation politics and more efficient management.
Highlights
Deforestation in Côte d'Ivoire is symptomatic to agricultural socio-economic development and forestry
The images processing based on the neuronal networks algorithm (Neural net) coupled to the ground data, was a significant asset to the land cover characterization with good classification accuracy
It put in relation some explanatory elements of the landscape due to the anthropogenic actions with the regression of the closed forests
Summary
Deforestation in Côte d'Ivoire is symptomatic to agricultural socio-economic development and forestry This development was carried out with the national forest inheritance detriment [1,2,3,4,5,6,7,8,9,10]. The carbon sequestration contributes it to mitigate the effects of the climatic changes All this justifies the protection of the forests ecosystems. In response to this situation of accelerated deforestation, and in a concern of the continuity of its natural resources, Côte d'Ivoire State carried out the protection of a significant part of its forest inheritance. The protected forests of the State, quantified with 147 in 1960, currently passed to 231
