Supply and Regulation Services Provided by Re-greened Landscapes in the Sahel: Case of Two Villages’ Clusters Dan Saga and Tabofatt in Niger Republic

The objective of this study is to assess the importance of the supply and regulation services provided by the regreened landscapes in certain anthropized areas of Sahel zone. The methodology used is based on a socioeconomic survey coupled with an inventory of woody vegetation in agroforestry parks in two villages’ clusters: Dan Saga and Tabofatt. Ethnobotanical analysis tools and allometric equations are applied on the data collected. These led to three main results. First, a total of 43 and 34 species registered are used in six (6) usages, such as food, forage, technological, energetic, and medicinal uses respectively both in Dan Saga and Tabofatt cluster. Second, the two landscapes contain a remarkable specific flora diversity which contributes not only to soil fertility but also to sequester 6.04±0.236 and 4.5 9±0.568 tCO2.ha-1 respectively at Dan Saga and Tabofatt. And thirdly in the landscapes of two clusters the amount of woody species inventoried, meets the amount of social use requirements. These results show that scaling up of regreening program should focus on promoting useful species through updating the current forest legislation.
