In Kinseki and Ntampa, the traditional oven (earth millstone) is the only technique used which is used in the process of the anti-ecological production of charcoal « makala ». Its qualitative and quantitative yield depends on the good handling of experienced and conscientious charcoal burners. Nevertheless, it leads to the destruction of biotopes, reduces forest or savannah biological diversity, degrades the soil, modifies the proper functioning of the biogeochemical and climatic cycles of the surrounding environment. Indeed, the majority of the peasant community remains in ecological ignorance which does not allow it to fight against the regressive series which characterizes the forest or the savannah, therefore the major concern of the charcoal burners is to have a large quantity of plant species in as little time as possible, without making a physical environmental accounting of the phytomass. This way of behaving transforms the primitive woody landscape into an anthropogenic grassy landscape and particularly accelerates deforestation. How to model with UML, the anti-ecological production system of charcoal, in order to fight against deforestation? What are the plant species most exploited by charcoal burners for the production of charcoal? With regard to these two questions, it is considered that the design of activity diagrams based on environmental and computer knowledge seems to be adequate to fight against deforestation; the most exploited species are those found in the savannas. The results obtained in the field show that the anti-ecological production of charcoal is practiced either in the forest (opinion of 88% of the subjects surveyed), or in the savannah (opinion of 12% of the subjects surveyed); no coal maker applies ecological principles (opinion of 100% of subjects surveyed); 91% of surveyed households are composed of more than 5 people against 9% who have only less than 5 people; 91% of the subjects surveyed have a low monthly income (i.e. less than $199); 100% of the subjects surveyed do not replace cut trees in the forest or savannah with others.
