ABSTRACT: This study deals with the perceptions of indigenous knowledge in the field of conservation and the impact of climate change on biodiversity in the peripheral villages of the Bouba-Ndjidda National Park (PNBN), Department of Mayo-Rey, Cameroon. To this end, 23 out of 70 villages in the study area were selected, for a sample of 368 households surveyed through a questionnaire addressed to the heads of households. Data collection took place from August 27 to December 22, 2022. The results reveal that 70.7% of the population living near the PNBN practice agriculture as their main income-generating activity, followed by livestock (23.3%) and trade (6%). Knowledge in the field of the conservation of natural resources is rooted in occultism through rituals and sacrifices (99.50%) offered to the geniuses of nature and prohibitions on the felling of trees and sacred animals (13.00%). The populations perceive climate change through the variation of the seasons (97.60%), the increase in temperature (84.80%), the reduction in the duration of the rainy seasons (54.60%), the drop in agricultural yield (84.80%) and floods (74.70%). The consequence of these changes on wildlife is the disappearance of animal species such as the Rhinoceros, the Wild Dog, the Cheetah and the Ostrich. In order to cope with climate change, the natives have developed strategies such as the adoption of early crop varieties (maize, millet, soybeans, etc.), the reorganization of the agricultural calendar, the practice of reforestation, extension of field surfaces, the cessation of excessive deforestation and uncontrolled bush fires, the construction of fired brick houses, the practice of irrigation, seasonal migration and occultism. This indigenous knowledge is a perfect adaptation to climate change and makes it possible to better take into account the vision of local populations in the conservation of biodiversity.
