Abstract

The Cameroon has two bamboo species indigenous to Africa (the alpine bamboo, Yushina alpina and the savannah bamboo, Oxytenanthera abyssinica), and one largely exotic species, Bambusa vulgaris. However, little on their physical characteristics and strength for the composites materials applications is known for these two indigenous bamboos species in Cameroon. Therefore, in this study, emphasis was laid on the alpine bamboo Y. alpina, to evaluate its potential for biocomposites applications. Y. alpina with ages ranging from 1 to 3 years, 4–5 years, and 7 years were characterized. The mechanical and physical properties of these three age ranges were compared. In the first place, the surface texture of the fibers was examined by scanning electron microscopy. Afterwards, chemical treatment was performed on the fibers with 1 % NaOH. In addition, the chemical bonds of the molecules (functional groups) were identified by Fourier transform infrared spectra (FTIR) and the thermal properties of the fibers were examined with a thermogravimetric analyzer. Furthermore, the fibers density was assessed using the Rilem protocol and a tensile testing machine was used to determine the mechanical properties of the treated fibers with 1 % of NaOH. Finally, a dynamic mechanical analysis of 7-year-old Y. alpina fibers was carry out. The results indicate that the Young's modulus of treated fibers with ages ranging from 1 to 3 years, 4–5 years, and 7 years were around 18 GPa, 10 GPa, and 14 GPa, respectively. In summary, this study underlines two primary points: (1) providing a platform for researchers to better understand the influence of age on the physical and mechanical properties of indigenous bamboo Y. alpina; and (2) providing a platform to validate suitable designs of biocomposites materials with Y. alpina.

Abstract

The fight against climate change is one of the major concerns of the international community and has led to a search to identify cost-effective ways to manage ecosystems in a way that removes atmospheric carbon-dioxide while providing essential societal benefits. As bamboo ecosystems in Cameroon are poorly known, this study sought to evaluate the distribution of bamboo, develop allometric equations for it and estimate carbon stocks associated with bamboo in the Western Highlands of Cameroon. Landsat 8 OLI imagery was used to increase data on the distribution and carbon stocks of Phyllostachys aurea Carrière ex Rivière & C. Rivière in the study area. P. aurea is reportedly the most exploited species for ecological, socioeconomic and cultural activities in the region, posing a challenge for the sustainability of the species. Twelve circular plots were established in P. aurea stands in the Western Highlands. Five per cent of the bamboo stems were harvested. Every stem was sorted into leaves, branches, and culms. These were weighed, and sub-samples taken to the laboratory. Sub-samples were oven-dried for biomass estimation. Regression analysis was used to develop the allometric equations. The best equation was used to estimate the carbon stocks. The Western Highlands region of Cameroon is estimated to have 241,296 ha of bamboos. The dominant bamboo species identified in the study area include Oldeania alpina (K.Schum.) Stapleton (syn. Yushania alpina K.Schum.), Bambusa vulgaris Schrad. ex J.C.Wendl. and P. aurea. Focusing on P. aurea the best fit equation with a bias of − 6.98%, Adj.R² = 0.711, AIC = 17 and RSE = 0.262, was selected. The mean density of P. aurea was 38,017 ± 4510 culms.ha−1. The mean culm aboveground biomass was 3.15 ± 0.94 kg. The AGB of P. aurea was estimated at 119.05 ± 3.63 t.ha−1, mean AGC was 55.95 ± 5.81 t C.ha−1 and mean aboveground carbon dioxide equivalence (AGCO2eq) was 205.35 ± 58.01.22 t CO2.ha−1. P. aurea constitutes a significant carbon sink in the Western Highlands of Cameroon. Policymakers and development planners should therefore recommend this species for carbon markets, international initiatives such as AFR100, and the Nationally Determined Contribution addressing the United Nations Sustainable Development Goal 13 (SDG13) to combat climate change.

Abstract

Over the last two decades, bamboo has received increasing attention owing to its socio-economic and environmental importance. Environmentally, bamboo plays an important role in carbon sequestration, thus enhancing climate change mitigation. In Cameroon, knowledge about the importance of Bambusa vulgaris Schrad. ex J.C.Wendl. to climate change mitigation is deficient, despite the fact that it is the most abundant bamboo species in Cameroon's Bimodal rainforest agroecological zone (Agroecological zone 5 - AEZ5). This study was initiated to develop allometric equations and estimate carbon stocks of B. vulgaris in Cameroon's AEZ5. The destructive, clump-based method was used for bamboo biomass data collection on 40 clumps and 86 culms. Regression analyses were performed to obtain allometric models for B. vulgaris biomass prediction which were used for B. vulgaris carbon stocks estimation in AEZ5. The best allometric model for culms was obtained when all predictive variables including age, diameter and height were considered into the model. For clump, the best model was obtained when the number of culms per clump, girth and average diameter were considered in the model. Model quality adjustment was better for clump aboveground biomass (AGB) compared to those of culm AGB. The model of B. vulgaris of the evergreen rainfall forest was validated with a bias of 45.5 %. Bamboo aboveground biomass proportions were 77 %, 15 % and 8 %, respectively for culms, branches and leaves. The mean density and carbon stocks of B. vulgaris were estimated at 2,0679 culms.ha−1, 257 clumps.ha−1, and 61.65 tC ha−1. B. vulgaris has a veritable carbon sequestration capacity which policymakers should consider in climate change mitigation strategies like those linked to payments for ecosystem services, voluntary carbon stocks market, Bonn Challenge, AFR100 initiative, and the Paris agreement ratified by the government of Cameroon.

Abstract

Rattan is an important Non-Timber Forest Product (NTFP) with huge potential to boost socio-economic development in indigenous communities of Cameroon in particular and the entire country in general. Rattan is mainly harvested from the wild, with no involvement of stakeholders in renewing the resource, leading to resource scarcity. Insufficient knowledge on rattan distribution and growth rate in Cameroon jeopardizes the sustainable management of its resource base. It was in this context that this study was initiated to (i) determine economically important rattan species and their distribution; (ii) identify their habitats and conservation status; (iii) examine harvester's perceptions/observations on annual growth rate and age of maturity. Findings revealed that Eremospatha macrocarpa exists in all AEZs, Calamus deerratus was found in AEZ 2 & 5, Laccosperma secundiflorum, L. Robustum, was found in AEZ 3, 4, and 5 and Eremospatha wendlandiana was found only in AEZ4. They grow in diverse habitat/environments with some habitats/environments specifically suitable for some rattan species. The current conservation status of commercial rattan species identified shows Least Concern (LC), but resource scarcity is high. Most harvesters observed that rattan takes either 2–3 years (51%) or 4–5 years (35%) to attain maturity. The harvesters' observation on the annual growth rate of economic rattan species varied in relation to the species and AEZs. However, overall 25% and 23% of the respondents observed a growth rate of 2–3 m and 3–4 m respectively. Kruskal-Wallis test shows a significant variation in harvesters' observations in the different AEZs for all growth and maturity parameters of different rattan species (p 0.05)”. All five economically important rattan species are widely distributed in the Southern part of Cameroon. The availability of E. macrocarpa in all zones indicates its great adaptation to different climatic and ecological conditions. Increasing the rattan resource base will involve its domestication, especially in the southern part of Cameroon where all rattan species thrive. The findings of this study are important for policymakers and development planners who seek to ensure the sustainable harvesting and management of the rattan resource base in Cameroon.

Abstract

Introduction: Today, bamboo is a resource frequently used by local people for their wellbeing and rural development in poor localities. Aims: This study aimed at identifying the ecosystem services offered by bamboo to the local population for their wellbeing. Duration and Place of Study: The study was carried out in January to February 2021 in Western highlands Agro ecological zone of Cameroon; more precisely in areas with high bamboo density according to literature review. Methodology: Three hundred and ten (310) questionnaires were administered to persons involved in bamboo activities including a direct observation in the field. This was complemented with key informant interviews. Results: The results showed that bamboo is highly utilized for subsistence purposes in many households in the Western Highlands of Cameroon, with at least 97 bamboo uses and products identified. These uses/products were grouped into 11 sectors/domains making use of bamboo. Agriculture, silviculture, handicrafts, furniture and house construction are the sectors using more bamboo products. Only 5% of respondents used bamboo in more than 10 sectors/domains. Conclusion: This baseline survey presents results which could orientate decisions of Policymakers and Development planners on how bamboo products could be valorized in the Western Highlands.

Abstract

Bamboo is of ecological and socio-economic importance in the world. However, knowledge on its potential in climate change mitigation remains superficial in Cameroon. The present study identified bamboo diversity and estimated carbon stocks of the dominant species in Cameroon. Ground truth method and local informants were used for a bamboo species survey in five Agro-ecological zones (AEZs). Twenty-two circular plots of 100 m² each were utilized for biomass and density data collection in AEZ 2, AEZ 3 and AEZ 4. Destructive method was used to collect 5% of culms per plot sampled for bamboo biomass estimation. Culm density and carbon stocks for each bamboo species were extrapolated to hectares. A total of 8 bamboo species were recorded in the inventory. Three dominant bamboo species were identified (Bambusa vulgaris, Oxytenanthera abyssinica and Phyllostachys aurea) in different AEZs. For the three dominant bamboo species, biomass of culm was greater (76-84%), than those of branches (13-19%) and leaves (4-9%). Culm density varied significantly across the different bamboo species, that is, 2296, 4374 and 38017 culm/ha respectively for B. vulgaris, O. abyssinica and P. aurea. Carbon stocks varied from 13.13 tC ha-1 (O. abyssinica); 29.62 tC ha-1 (B. vulgaris) and 67.78 tC ha-1 (P. aurea), with significant variations (P< 0.05) across the different bamboo species. The fast growth rate of bamboo underpins its potential for climate change mitigation and could influence decisions and strategy for the fight against climate change in Cameroon. Key words: Agro-ecological zone, climate change mitigation, culm density, REDD+ strategy, Cameroon.

Abstract

Ecotourism has been reported as a sustainable measure of bridging conservation goals and livelihood sustenance around protected areas, with very little information on the Campo Ma’an National Park (CMNP). This study was initiated to assess the impact of ecotourism activities on the livelihood of the local population living around the CMNP. Data were collected with questionnaires through household surveys and focus group discussions, interviews with key informants and observations in 9 communities. Chi-square test, Spearman’s rank correlation and regressions were used for data analysis. The study revealed that 65% of the local population perceived that ecotourism activities do not contribute to livelihood improvement. Chi-square statistics and Spearman rank correlation coefficients showed that the main factors plausibly affecting the impact of ecotourism activities around the CMNP on the local population’s livelihood were community, gender, main and secondary occupation, level of education, ethnic group, and number of children. Coefficients of the logistic regression model indicated that the main factors influencing the impact of ecotourism around the CMNP on the local population’s livelihood were gender (β = 1.218; p

Abstract

Forest understorey contains remarkable plant diversity, contributing to the heterogeneous environments for other biotic gatherings and soil supplement aggregations. Nonetheless, the biomass of the understorey vegetation is neglected because of the lack of appropriate allometric equations without which there are uncertainties in biomass estimation. This study was aimed at developing multispecies allometric equations that will be used to estimate the aboveground biomass of different compartments (trunk, crown, and leaves) of understorey trees in the semi-deciduous rainforest of Cameroon. Understorey tree diameter (1.0-10.0 cm), height, and crown diameter were measured on 1023 trees as biomass predictors. The results showed that the fit of the model improves with more predictive variables, four of which were considered in all studied compartments (trunk, crown, and leaves). Existing specific and pantropic allometries based on diameter tend to overestimate the aboveground biomass of understorey trees when compared to the allometry developed in this study. This study highlighted the importance of a specific aboveground biomass allometric equation for understorey trees. Furthermore, the multispecies allometric equation developed for understorey trees complements those recently developed for overstorey trees, thereby contributing to the total aboveground woody biomass estimation in semi-deciduous forest in the Congo Basin.

Abstract

Background: Rattan is an important Non-Timber Forest Product (NTFP) with huge potentials to boost socio-economic development in indigenous communities of Cameroon in particular and the entire country in general. Exploitation is from the wild, with no implication of stakeholders in renewing the resource, thus leading to resources scarcity. Insufficient knowledge on rattan’s growth potentials in Cameroon jeopardize resource regeneration and renewal. It was in this context that this study was initiated to (i) determine economically important rattan species distribution; (ii) identify their habitats and conservation status; (iii) examine harvester’s perceptions/observations on annual growth rate and age to maturity. Results: It was found that Eremospatha macrocarpa exist in all AEZs, Calamus deerratus was found in AEZ 2 & 5, Laccosperma Secundiflorum, L. Robustum, was found in AEZ 3, 4 and 5 and Eremospatha wendlandiana was found only in AEZ4. They grow in diverse habitat/environments with some habitats/environments specifically suitable for some rattan species. The current conservation status of commercial rattan species identified shows Least Concern (LC); but resource scarcity in high. Most harvesters observed that rattan takes either 2 – 3 years (51%) or 4 – 5 years (35%) to attain maturity. The harvesters’ observation on annual growth rate of economic rattan species varied in relation to the species and AEZs, nevertheless, globally 25% and 23% of the respondents observed a growth rate of 2-3 m and 3-4 m respectively. Kruskal-Wallis test shows a significant variation in harvesters’ perception in the different AEZs for all growth and maturity parameters of different rattan species (p0.05)”.Conclusions: All five economically important rattan species are highly distributed in the Southern zone of Cameroon. The availability of E. macrocarpa in all zones indicates its great adaption. Renewing (plantations) rattan resource implies appropriate planting in the Southern and Coastal regions of Cameroon, since the all the species inhabit and grow rapidly. This is important to policymakers and development planners for policy reformulation towards the sustainable development of rattan in Cameroon.
