The practice of the assisted natural regeneration (ANR) is essential to remedy the fatal effects of the climate change on the ligneous resources however it is subject to multiple constraints. The present work aims to characterize the ANR in the agroforestry parklands; look for its origins; identify the main climatic factors and their shocks on the ANR; propose strategies to improve this practice. Therefore 55 plots of inventories were settled on various agroforestry parklands. Individual interviews and brainstormings were realized with the farmers to identify the climatic factors observed in the village, the shocks perceived on the ANR and the strategies of improvement. The intensities of these shocks related to climate change were assessed by the indices of severity and incidence. This study shows that 28 woody species from 18 families and 27 genera are regenerating in agroforestry parklands. Three origins characterize the ANR species: spontaneous regeneration; budding strains; zoochoria and organic manure. Some factors affect the practice of the ANR. From these factors emanate 16 shocks of various severities and incidences. Finally, five strategies for improving the practice have been identified.
