“…These differences were attributed not only to the plant species composition of fallow, in contrast to the methodological difference, especially the definition of young and old fallow. In fact, in our study, the age of young fallows is between 1 and 2 years whereas it is 4 to 8 years in the studies of Anobla and N'Dja [46], 5 years in those of Kaïré [51], Da Costa [41] and Palm et al [48], less than 10 years in those of Mass [52]. Similarly, the age of old fallows is 20 years in our work and those of Kaïré [51] versus 10 years in the work of Mass [52] and 25 years in those of Palm et al [48].…”

“…Indeed, in Saré Yorobana, in southwestern Senegal, Kaïré [51] found in the fallows of 5, 10, 15 and 20 years, an increase in the carbon stored in the biomass of 5, 11, 15 and 18 tC.ha -1 , respectively. The results obtained by Mass [52] in the same site as Kaïré [51] showed that fallows less than 10 years accumulated on average a carbon stock (soil + plant) of 17.5 tC.ha -1 , whereas Fallows older than 10 years averaged 22.5 tC.ha -1…”

Aim/Objectives: In order to assess the fallow contribution on the carbon cycle and soil organic matter restoration, a study of the carbon dynamics was undertaken in fallow systems of 1, 2, 5 and 20 years old in the Ngaoundere savannahs of Cameroon. Methodology: Carbon stock was estimated in 100 m2 plot for shrubs, in 1 m2 plot for understorey, litter and earthworm casts, and 0.0625m2 plot for fine roots and soil. The experimental design was randomised complete block with three replicates. The age of fallows was the mean treatment whereas the plots were the replicates. Results: The results showed that the phytomass increased with fallow age, except that of shrubs. Soils and earthworm casts were the mean carbon sinks in the four fallows, with more than 55.61% and 26.24% of the total carbon stock respectively in the soil and earthworm casts. The total carbon stock increased with fallow age, from 34.54 in the young fallows to 154.52 tC.ha-1 in the old fallows. In the same way, vegetation and soil carbon increased with fallow age except that of shrub. The results showed that the carbon stock was influenced by floristic composition and spatial distribution of the vegetation, which related to fallow age. Conclusion: These preliminary results will contribute to the understanding of the impact of fallow age on the global carbon cycle and awareness in the conservation of fallows for the environment protection.

“…Kashaigili and Majaliwa [ 16 ] also realized a reduction in carbon stock from the year 1980 to 2010 in two forests of Tanzania due to forest cover change. Similarly, Gond et al [ 74 ] also reported a 30% loss in carbon stock from 1984 to 2012 in wood-fuel supply basin of Kinshasa. Furthermore, Gaston et al [ 44 ] showcased a loss in above ground carbon stock by 6.6 Pg due to forest degradation in tropical Africa between 1980 and 1990.…”

BackgroundForests play an important role in mitigating global climate change by capturing and sequestering atmospheric carbon. Quantitative estimation of the temporal and spatial pattern of carbon storage in forest ecosystems is critical for formulating forest management policies to combat climate change. This study explored the effects of land cover change on carbon stock dynamics in the Wujig Mahgo Waren forest, a dry Afromontane forest that covers an area of 17,000 ha in northern Ethiopia.ResultsThe total carbon stocks of the Wujig Mahgo Waren forest ecosystems estimated using a multi-disciplinary approach that combined remote sensing with a ground survey were 1951, 1999, and 1955 GgC in 1985, 2000 and 2016 years respectively. The mean carbon stocks in the dense forests, open forests, grasslands, cultivated lands and bare lands were estimated at 181.78 ± 27.06, 104.83 ± 12.35, 108.77 ± 6.77, 76.54 ± 7.84 and 83.11 ± 8.53 MgC ha−1 respectively. The aboveground vegetation parameters (tree density, DBH and height) explain 59% of the variance in soil organic carbon.ConclusionsThe obtained estimates of mean carbon stocks in ecosystems representing the major land cover types are of importance in the development of forest management plan aimed at enhancing mitigation potential of dry Afromontane forests in northern Ethiopia.Electronic supplementary materialThe online version of this article (10.1186/s13021-018-0103-7) contains supplementary material, which is available to authorized users.

“…The PB area is one of the main supply zones of the capital city Kinshasa with over 10 million inhabitants, supplying an estimated 40% of its total demand (Projet Makala, 2011). The area has known a significant reduction of forest stock and degradation due to shifting cultivation and charcoal production, with an estimated decrease of carbon stock by 75% over 20 years' time (Gond et al, 2016).…”

Le charbon de bois restera une source d’énergie importante en Afrique subsaharienne dans un avenir prévisible, le présent article se concentre sur l’amélioration de l’efficacité de la carbonisation comme contribution à des chaînes de valeur plus durables du charbon de bois. Alors que l’efficacité de la conversion du bois en charbon est souvent considérée comme une question technique de performance des fours, cette étude vise à mettre en lumière le rôle d’un contexte institutionnel favorable et les capacités des acteurs impliqués. Sont d’abord passées en revue les initiatives visant à améliorer la production de charbon de bois dans différents pays d’Afrique subsaharienne. Nous comparons ensuite les données sur les processus de carbonisation dans deux zones en République démocratique du Congo : Yangambi et le Plateau de Bateke. Les principales conclusions sont les suivantes : 1) l’amélioration des techniques de carbonisation permet de réaliser d’importants gains en termes de taux de conversion du bois en charbon, mais le succès dépend en grande partie de l’adéquation des solutions de four en fonction du contexte, de la capacité et de la sensibilisation des producteurs et du contexte institutionnel favorable ; 2) le renforcement des capacités des opérateurs et des autres parties prenantes nécessite des techniques de four efficaces, mais aussi une sensibilisation accrue aux avantages et aux options d’approvisionnement durable, le renforcement des compétences financières et de gestion des organisations de producteurs et l’amélioration du transport, de la manutention et de la commercialisation ; 3) le statut illégal ou informel des producteurs de charbon de bois en Afrique subsaharienne nuit à l’efficacité des processus de production du charbon, tandis qu’un cadre institutionnel adéquat facilite l’accès des producteurs aux permis et au financement, fournit une fiscalité claire avec des incitations pour des pratiques plus durables et relie les exigences techniques en termes de carbonisation aux sources et utilisations finales durables. Le succès ou l’échec des techniques de carbonisation améliorées et les résultats socio-écologiques connexes sont déterminés conjointement par les solutions qui incluent les aspects de renforcement des capacités, d’acceptabilité et d’institutions favorables identifiés dans cet article. La poursuite du développement de ces solutions en partenariat avec les producteurs accroît le potentiel de chaînes de valeur plus durables pour le bois-énergie.
