“…With ρ= density of wood by species. Wood density was determined using an approach similar to that used by Peltier et al (2007), Henry et al (2010) and Moussa and Larwanou (2018). This approach involves taking samples of wood from each species and determining its volume by means of a graduated test tube (500 ml) in the laboratory.…”

“…This approach is widely used to assess errors related to the prediction of a biomass estimation model (Fayolle et al, 2013;Moussa and Larwanou, 2018). To avoid errors related to the back transformation, the correction factor was calculated for each model using the following formula (Chave et al, 2005;Mascaro et al, 2014):…”

“…The performance of each model was first assessed by checking the homogeneity and normality of the standardized residuals (Zuur et al, 2010). Second, the model was accepted when the significance of the coefficients and the regression was justified and the errors were small (Sileshi, 2014;Moussa and Larwanou, 2018).…”

“…Thus, the accumulation of woody biomass in these ecosystems is important because of its environmentally and socio-economically important roles in the protection of lowland agrosystems and the aboveground fodder it provides to animals, and particularly large ruminants (Chaibou et al, 2012). In the southern part of Niger, important data on the quantity of sequestered carbon in agroforestry parklands have shown that the quantity varies depending on the relative density of trees (Weber et al, 2018;Moussa and Larwanou, 2018).…”

“…Due to a lack of field data, especially on land use, land use changes and forestry sectors, default data have been regularly used according to the National Council for the Environment for Sustainable Development in 2014. There is little information on allometric models for estimating biomass concerns in the Sahelo-Sudanian zones of the country (Moussa, 2016;Weber et al, 2018;Moussa and Larwanou, 2018). In addition, none of the pantropic or generic models address the Saharan zone of Niger (Brown, 1997;Chave et al, 2005;Henry et al, 2011;Chave et al, 2014).…”

Maintaining the economic, ecological and social services provided by the oases and the valley ecosystems of Aϊr, in the northern part of Niger, is important for local communities. The purpose of this study is to evaluate the supply and regulation services provided by these ecosystems through wood energy and carbon sequestration. Semi-structured surveys and dendrometric parameter measurements of woody species were carried out. In total, 9 villages were surveyed, and 558 trees of all woody species were inventoried in 65 plots. Most of the resources are distributed in lowlands and valleys along the toposequence. These topographical units are favourable for the accumulation of rainwater and also serve as resources for the wellbeing of the local population, especially their wood energy needs. Businesses have developed around the production and sale of charcoal. The carbon stock of the woody species was found significantly varied (P ≤ 0.05) between the different topographical units. Four allometric models of carbon estimation were developed, of which the model with diameter at breast height (DBH), height and wood density as the predictor variables was the most efficient. This study can be used for the formulation of policies and strategies for the sustainable management of Aïr Massif's natural resources to benefit the welfare of local communities.
