Abstract |
|
The present study estimated the impact of wood
loggings on the phytomass production and carbon
sequestration in the guinea savanna of Ngaoundéré,
Adamaoua Region, Cameroon. The results showed that
the phytomass of arborescent savanna is more
important (169.91 t.ha-1.year-1)
than that of the shrubby savanna (49.18 t.ha-1.year-1).
The sequestration of carbons correlated positively
with phytomass (r= 0.98, P = 0.05). The very strong
wood loggings (T3) are at the origin of the decline
of phytomass production (36.53 tc.ha-1.year-1)
and of the sequestration of carbons (17.17 tc.ha-1.year-1)
in these savannas. These values are indicators of
degradation of the outer-urban savannas in
Ngaoundéré. The State government and the local
population should jointly embark on the management
for the protection of savannas in the Region.
