Perception paysanne des ligneux à houppier fermé dans les agrosystèmes de Gaya : cas du terroir villageois de Tanda (République du Niger)

Abstract

Objectives: This study aims to establish a diagnosis on the peasant perception of closed crown trees and management practices in the agro-ecosystem of Tanda in the north-Sudanese zone in Niger Methodology and Results: The methodology was based on a systemic approach taking into account the concepts of agro-ecosystem and agroforestry practice. Thus, they were apprehended through surveys of 74 owners of domain with at least one domain in the locality land and trees measurements (height, diameter at 1.3 m; crown) on 73 plots of 2500 m2 each. The results show that the woody park is formed of 31 species, divided into 14 families, with an average density of 29.2519.83 individuals unit/hectare and an overall recovery of 7.87%. Conclusions and application of findings: Conclusion and applicability of the results: In this agrosysteme, producers distinguish well the advantages and disadvantages of woody species in closed crown. Species that provide non-timber forest products such as high-value Vitellaria paradoxa, Adansonia digitata, Parkia biglobosa and Mangifera indica, are highly desirable and maintained in the field. By cons, unwanted woody plants in a field are thorny, those serving as dormitories for birds and those with shading effect on crops. Which are important parameters for all players reforestation policies in the area. To mitigate the effects of these negative interactions, producers implement agroforestry practices which include: pruning timber at specific times of the crop calendar, changing crop management sub-covered crops, forage harvest animals in stables and gathering of non-timber forest products. A more detailed analysis of the effects of such practices is needed to develop a more sustainable and efficient operating model production.
