Title: EVALUATE THE SOCIO-ECONOMIC IMPACT OF THE REALIZATION
OF HALF-MOONS AND FOREST BENCHES, THEIR DURABILITY AS
WELL AS THEIR INFLUENCES ON THE PLANTATIONS OF Eucalyptus
camaldulensis AT THE VILLAGE OF SATARA, COMMUNE OF SIMIRI,
DEPARTMENT OF OUALLAM, REGION OF TILLABERY IN NIGER,
WEST AFRICA. |
Abstract: This study was conducted in the rural commune of Simiri, village of SATARA, located north of
Niamey (capital city of Niger) at about 70 km. Its general objective is to evaluate the socioeconomic
impact of the realization of half-moons and forest benches, their durability as well as
their influences on the plantations of Eucalyptus camaldulensis. The specific objectives are:i) To
evaluate the socio-economic impact of cash for work on the beneficiary population, ii) To
evaluate the level of degradation of half-moons and forest benches, iii) To evaluate the behavior
of Eucalyptus camaldulensis in half-moons and benches, iv) Characterize the structure of the
root system developed by Eucalyptus camaldulensis in half-moons and forest benches.
The methodology adopted during this study was to rely on precise data collected through the
socio-economic survey, measures of design of the structures, the dendrometric measurements,
and the excavations of the root systems of Eucalyptus camaldulensis. The results obtained from
the exploitation of these data are as follows: 1) The benefits derived from cash for work have
contributed to the strengthening of the resilience of the beneficiary populations, 2) The technical
standards for the construction of the works have been respected to more than 90% on the half-moons as on the forest benches, on the other hand the phenomena of sagging of the beads and
silting of the channels are more visible on the half-moons than on the benches, 3) Eucalyptus
camaldulensis planted in the forest half-moons grew much in circumference, height, crown
diameter as that planted in the benches, 4) The structure of the root systems of Eucalyptus
camaldulensis was more favorable to the absorption of water in the half only in the benches. |
