Abstract:
This study on the restoration of land degraded by Soil Conservation and Soil Defense and
Restoration (CES/DRS) technics was conducted in the rural community of Loga (Niger), at the
village of Badoko. The study assessed some land restoration actions carried out to evaluate
assess the level of their contributions to the resilience of agricultural land to climate change.
The methodology used is based on socio-economic surveys, measurements of the technical
standards of run off cashment structure (Bench) and the dendrometric survey of planted trees in
naturally regenerated in Benches structures.
The results showed (1) that communities are aware of the degradation of natural resources that
has been restored using the benches appreciated and accepted by the populations; (2) that the
money obtained by the beneficiaries has enabled households to eat well; (3) that the vegetation at
the site was markedly improved by a high floristic richness (woody and herbaceous) with 0.63
bits of diversity and 0.59 bits of Pielou's equitability. This reflects an instability of the species in
the environment whereas the Pielou equitability index follows the opposite trend; (4) that the
species Acacia senegal and Bauhinia rufescens recorded the highest survival rates and the largest
increases in diameters and heights; (5) that the high mortality of the species Ziziphus mauritiana
is related to the eccentric position of this species which is found on the last rows of the Benches
structures with a small supply of runoff water and the presence of the rodents which damaged the
young Plants during their development. |
