ENVIRONMENTAL AND ECONOMIC INFLUENCES OF LAND OCCUPANCY IN THE COMMUNITY OF DJIDJA

Land resources are limited and changing at unprecedented rates. The pressure on the latter becomes daily more and more important. The objective of the study is to present the environmental and socio-economic influences of land occupation in the municipality of Djidja. The research methodology is based on data collection, manual and statistical processing of data and analysis of results. Surveys are made from 271 heads or representatives of households and resource persons. The basic considerations of the socio-economic scenario contribute to the reduction of the lifespan of plant formations, as these will be subject to anthropic pressures. In fact, it has been noted in the case of this scenario, an amplification of human pressures in particular, the extension of plantings, the intensification of shifting cultivation on slash-and-burn, the massive destruction of natural plant formations with the consequent naked and soil pollution, amplification of water and wind erosion followed by huge losses of agricultural land. , agricultural producers, through their various associations are informed and integrated into the environmental management plan, through the creation and operation of several local action committees. When these different conditions are met, we will see the horizon 2050, environmental stability with an equitable distribution of different units of land use in the municipality of Djidja. This situation will prevent the study area from the climatic disturbances that it has suffered for decades. In short, the scenario of environmental stability or scenario '' Alafia '' is that desired for a sustainable management of the environment in the Municipality of Djidja. The overall performance of the simulation is 87.15% with a Kappa index of 83%. The results according to the types of units of occupation are relatively homogeneous, since they exceed 70% of precision for the producer, with however better results for artificialized units, agglomerations, fields and fallows.
