Carbon Sequestration Potential and Economic Value in Agroforestry Parkland to Tectona grandis L. f. (Verbenaceae) in Central Africa: A Case Study to Department of Poli (Northern Region in Cameroon)

Abstract

The vegetation and the afforestation of agricultural land non-forest represent a potential increase in carbon stocks which could, under certain conditions and within certain limits, compensate part of the emissions resulting from the use of fossil fuels and deforestations. Quantification of stocks of biomass and carbon dioxide contained in agroforestry systems has become an international priority within the framework of the implementation of REDD+ mechanism. Estimates of stocks of carbon in woody biomass, dead organic matter, belowground biomass, litter, herbaceous and lianas plant biomass were incorporated in allometric equation based on non-destructive method. The total carbon stock evaluated in the parkland of Tectona grandis was 207.34 ton/3ha out of which woody biomass accounted for 130.19 ton/3ha belowground biomass (40.4 ton/3ha), dead organic matter (22.85 ton/3ha), litter (9.09 ton/3ha), herbaceous plant biomass (2.28 ton/3ha) and lianas (2.53 ton/3ha). The aboveground biomass therefore contributed approximately 62.80 % of the total stock of carbon assessed. This show the considerable contribution of Tectona grandis parkland to climate change mitigation in Cameroon.

Local Communities Implications’ in Managing Woody Species and Carbon Accumulation in Sahelian parts of Maradi Region, Niger Republic

“…This is consistent with the findings ofSiriki et al (2022) who concluded that the amount of carbon sequestered in agroforestry systems is linked to the circumference of trees which is linked to the diameter. This is in line withVictor et al (2019) who reported that more a tree has a large circumference, more he occupies an important basal area and receive a large quantity of carbon. In addition to this,Wafa et al (2016) showed that trees in drylands can increase biomass carbon stocks.The tree species are promoted and protected by local communities through natural regeneration in the agroecological zones in Maradi Region.…”

“…In addition to this,Wafa et al (2016) showed that trees in drylands can increase biomass carbon stocks.The tree species are promoted and protected by local communities through natural regeneration in the agroecological zones in Maradi Region. These results corroborate those found bySiriki et al (2022) who reported that, the rate of carbon sequestered by agroforestry systems depends on the maintenance techniques of these systems in Dioïla Région(Mali Republic).Thereby, good practices represent a potential increase in carbon sequestration and fight against climate change through carbon storage(Victor et al, 2019;Mensah et al, 2020;Elvire et al, 2023) through the presence of trees in agricultural system. These systems with good practices play an important role through…”

Dynamics of soil organic carbon stock under different types of savannah agrosystems in the Sudano-Sahelian zone of Cameroon

“…This organic matter generally comes from dead, mainly plant organs and organisms, animal excreta, root exudates and living organisms (Gorham et al, 2020). The organic matter (OM) then undergoes biotransformation in the soil : biodegradation and finally mineralization, which returns the Carbon to the atmosphere in the form of CO2 (Awé et al, 2019a). Carbon exchanges between the atmosphere and terrestrial ecosystems are about ten times greater than the emissions caused by the use of fossil fuels (FAO, 2017).…”

Assessing the Contribution of Citrus Orchards in Climate Change Mitigation through Carbon Sequestration in Sargodha District, Pakistan

“…In the terrestrial ecosystem, carbon sequestration is achieved by photosynthesis, which eliminates carbon from the environment and deposits in the biosphere [5,6]. Biomass is considered a vital carbon reservoir in the terrestrial ecosystem, thus playing a crucial role in the global carbon cycle [7].…”
