Abstract:

Bamboo is proven to provide multi-benefits from the aspects of production, ecology and socio-economic. However, bamboo is still not fully developed. People tend to replace bamboo with wood species which are considered to be more profitable, one of them is sengon. The purpose of this study was to analyze bamboo management practices carried out by farmers and compare between sengon and bamboo cultivation which is more financially profitable. Financial analysis conducted includes: Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR). Analysis of market aspect and social aspect using the Market Analysis and Development (MA&D) method. The sensitivity analysis is carried out on the condition of fixed income while costs increase by 10% and 30% and fixed costs while income rises by 10% and 30%. The analysis included the analysis of market aspect and social aspect. The results of the financial analysis showed that the cultivation of petung bamboo with a spacing of 6x6 meters gave the highest yield with NPV value of IDR330.329.538, BCR 29.10 and IRR of 25.18%. Nevertheless; looking at market and social aspects, bamboo and sengon can be developed in agroforestry to ensure sustainability and continuity of income for farmers. Bamboo and sengon cultivation business is feasible to be conducted because the high demand which cannot be met from the existing sources.

Abstract:

Balustrade architecture is mainly distributed in south and southwest China and southeast Asia. Dai dwellings in Yunnan, China, are a typical balustrade dwelling. Traditional dwellings of Dai contain the concepts of architecture, physics, ecology, and sustainability in space planning, building materials, and construction methods. At a time when the global climate environment is deteriorating and energy saving, emission reduction, and low-carbon life are advocated, Dai dwellings should be studied from the perspective of sustainable development, from which we can draw lessons and inspiration. This paper investigated plane layout, space structure, and materials of Dai dwellings, and found that traditional Dai dwellings are wooden frame structures with wood and bamboo; the roof has two layers and long overhang eaves, which is good for diverting rain water, shading and shelter, and integrating the building with the natural landscape as well. Analyzing the spatial characteristics and problems of Dai dwellings at present, discussing the sustainable development ideas of Dai dwellings, constructing Dai dwellings with low energy consumption and high quality of life, combining traditional culture with ecological technology, and designing a sustainable new green living model are beneficial to the inheritance of Dai residence culture.

Abstract:

The 18-year history of bamboo craftsmanship in the university curriculum of Taiwan started with the popularization of concepts such as green design, community building, and cultural and creative industries. Bamboo is an environmentally-friendly material that has received much attention in the 21st century. Craftsmanship has drawn the attention of universities. This study uses participatory observation and interviews to collect information on bamboo craft courses in four departments of three universities and uses qualitative coding analysis to explore the sustainable teaching methods of craftsmanship teachers, sustainable development learning effects on students, and different ways of promoting sustainable development education (ESD) with bamboo craft courses in different universities. The research results show the following: (1) There are differences in bamboo craft courses: teachers’ craftsmanship and curricula are different, resulting in differences in technical depth and creativity; (2) with respect to the ESD evaluation criteria of the four bamboo craft courses, skills learning itself is not complete, but students are provided with a path to self-reliance in the craft and in responding to cultural sustainability challenges; and (3) regarding the relationship between ESD and bamboo craft education, bamboo craft education promotes the concept of sustainability and is important for the creation of crafts; universities offer opportunities for testing students’ technical talents and knowledge, but ESD is limited and blurry.

Abstract:

Fast-growing biomass, such as bamboo, has the potential to serve an important future role in the pulp and paper industry with potential to both lower resource costs and improve a product’s sustainability. Moso bamboo is particularly interesting due to its fast growth and size, which allows it to be handled and chipped similarly to wood resources. In this study, we will share results of the chip preparation, kraft cooking, and ECF bleaching of this bamboo species and compare its pulpability, bleachability, and physical properties to a fast growing hybrid poplar tree. Results indicate that the bamboo chips cooked and bleached similarly to the poplar hardwood, allowing for co-cooking. The resulting pulps had superior tensile properties at low refining, but did have higher fines that lowered drainability as measured by Canadian Standard Freeness. The bamboo fiber morphology was also measured, indicating the fiber to have length weighted average fiber lengths and coarseness values to be greater than the poplar wood studied, which should allow this material to be used in many paper grades.

Abstract:

It is foreseeable worldwide that in the future the topic of sustainability will have to be given greater importance. The same applies to the building industry. Bamboo is a natural, very fast growing raw material with very good properties which have great advantages in many areas. It doesn't grow all over the world, but it already has a lobby in non countries of origin. Now the question arises whether bamboo can become more important in the future as a building material in non-countries of origin due to sustainability problems. First of all the work deals with the climatic conditions that bamboo needs to grow and why it can't grow all over the world. Subsequently, bamboo as a raw material is discussed and it is worked out whether it has the right properties for an alternative and what could make it such a good alternative material. It is examined whether he can supplement or even replace other materials in countries of origin. Properties are confronted and compared. My results show that bamboo, due to its properties and applications, has the potential to be a complement and/or an alternative to other building materials. However, there are some small factors that speak against it. Further my results have shown that fundamentally much more thought has to be given to sustainable building. Bamboo can become a big factor of sustainability in the building industry in the future, but it is not enough to rest on it and the topic must be given a more important meaning.

Abstract:

Microwave heating is proposed as a kind of pretreating methods for bamboo fiber extraction. Effect of various processing parameters, e. g. microwave initial-setting power, reaction temperature, irradiation time, and bath ratio (bamboo to water) on bamboo powders was studied. Analysis of chemical components indicates that microwave assisted extraction is a mild treating method without obvious change of main constitutes of bamboo. The removal of polysaccharide by microwave treating resulted in loosening the structure and thus benefits hydrolysis of bamboo in subsequent.

Abstract:

A combined technology of high-temperature heating and microwave is proposed to treat bamboo substrates prior to enzymatic hydrolysis to overcome the limits of ei- ther technology. The combined technology helps to promote the reducing sugar yield from enzymatic hydrolysis of bamboo. The protein adsorption test indicated that more enzyme proteins could adsorb on the surface of bamboo pretreated by the combined technology. Thus, the possibility of enzymes to hydrolyze bamboo increased. Meanwhile, X-ray diffractometry tested revealed that the combined technology benefited the removal of non-cellulosic substances from bamboo and resulted in a higher crystallinity.

Abstract:

Bamboo processing was performed with commercial cellulase. The properties of cellulase and the effect of high temperature pretreatment on cellulase hydrolysis of bamboo were investigated. Results indicated that cellulase hydrolysis performed fast and dramatically within 30 minutes, and then gradually reached its balance. It was found that pretreatment played an active role in cellulase processing, which enhanced the saccharification of bamboo and benefited high-molecular-weight lignin degradation and removal. Additionally, a better performance of bamboo processing was achieved under the cellulase concentration of 15IU in total reaction system of 100 ml at 50?C, pH 4.8, together with the high temperature pretreatment of 120?C for 15 minutes.

Abstract:

We investigate a hypothesis for explaining maintenance of forest canopy dominance: bamboo (Guadua weberbaueri and Guadua sarcocarpa) loads and crushes trees, resulting in a self-perpetuating disturbance cycle. Forest inventory data revealed a peculiar pattern of tree form and size class distribution in bamboo-dominated plots within the Tambopata River watershed, Madre de Dios, Peru. Bamboo disproportionately loaded trees 5–29 cm in diameter, and this size class had over seven times more canopy damage than trees in control plots without bamboo. These differences were accompanied by reduced tree basal area and tree density in the 5–29-cm-diameter size class in the presence of bamboo. Elevated tree canopy damage was not apparent for trees ≥30 cm dbh, which are beyond the reach of bamboo. Additional evidence for the impact of bamboo was revealed by an experiment using artificial metal trees. Artificial trees in bamboo-dominated forest plots had nine times higher frequency of physical damage and nine times more plant mass loading as compared with control plots. Our results support the hypothesis that bamboo loading causes elevated physical damage to trees and suppresses tree recruitment, particularly for trees 5–29 cm in diameter.

Abstract:

Abstract. Bamboo-dominated forests comprise 1 % of the world's forests and 3 % of the Amazon forests. The Guadua spp. bamboos that dominate the southwest Amazon are semelparous; thus flowering and fruiting occur once in a lifetime before death. These events occur in massive spatially organized patches every 28 years and produce huge quantities of necromass. The bamboo–fire hypothesis argues that increased dry fuel after die-off enhances fire probability, creating opportunities that favor bamboo growth. In this study, our aim is to map the bamboo-dominated forests and test the bamboo–fire hypothesis using satellite imagery. Specifically, we developed and validated a method to map the bamboo die-off and its spatial distribution using satellite-derived reflectance time series from the Moderate Resolution Imaging Spectroradiometer (MODIS) and explored the bamboo–fire hypothesis by evaluating the relationship between bamboo die-off and fires detected by the MODIS thermal anomalies product in the southwest Amazon. Our findings show that the near-infrared (NIR) is the most sensitive spectral interval to characterize bamboo growth and cohort age. Automatic detection of historical bamboo die-off achieved an accuracy above 79 %. We mapped and estimated 15.5 million ha of bamboo-dominated forests in the region. The bamboo–fire hypothesis was not supported because only a small fraction of bamboo areas burned during the analysis timescale, and, in general, bamboo did not show higher fire probability after the die-off. Nonetheless, fire occurrence was 45 % higher in dead than live bamboo in drought years, associated with ignition sources from land use, suggesting a bamboo–human–fire association. Although our findings show that the observed fire was not sufficient to drive bamboo dominance, the increased fire occurrence in dead bamboo in drought years may contribute to the maintenance of bamboo and potential expansion into adjacent bamboo-free forests. Fire can even bring deadly consequences to these adjacent forests under climate change effects.

Abstract:

To assess the impact of a dense understory of the bamboo Yushania microphylla Munro on tree regeneration in monospecific Abies densa Griff. stands of the central Bhutan Himalayas, the age-class distribution of fir regeneration, the microsite preferences, and height growth as well as the relationship between height of the bamboo, gap fraction, and tree seedling density were studied. Seedling densities were much lower on sites with bamboo. Recruitment was more or less continuous, and there was no indication of overall synchronized single-cohort regeneration in bamboo plots. On sites with bamboo understory, the light regime at the forest floor is strongly influenced by the height of the bamboo. A large portion of the variance of tree seedling density could be explained by the height of the bamboo. The mortality of fir seedlings is considerably reduced at elevated microsites. Fir establishment on the forest floor is restricted to sites where bamboo density is low and light levels are higher. On sites with dense, unbrowsed bamboo, light levels are too low for long-term survival of fir seedlings, resulting in a lack of suppressed regeneration with minimal height growth. Because of the absence of this fraction, the average height increment of fir seedlings is higher on sites with bamboo.

Abstract:

We document the perceptions, practices and policy options in managing lowland bamboo [Oxytenanthera abyssinica] in Benishangul Gumuz Regional State (BGRS) in Ethiopia, particularly to enable small-scale enterprises (SSE) to become more active in this field. This region hosts the largest extent of natural bamboo forests in Ethiopia. There is a recent push to realize bamboo's economic and environmental potential in Ethiopia, which puts SSEs as crucial actors. There is little or scattered published information on local perceptions and practices surrounding natural bamboo forest management and options for realizing bamboo's potential from a subnational/local perspective in Africa, including in Ethiopia. In 2018, we conducted a literature review, spatial analysis, participatory mapping, and interviewed experts working in governmental and non-governmental organizations and local stakeholders in BGRS. We find some consensus of the environmental importance of bamboo. In contrast, there is some debate at the subnational level about the economic importance of bamboo, leading to decisions favouring other land uses. Bamboo forests in this region suffer neglect, as they are perceived to be 'owned by no one and used by everyone' and will continue to be there without management. Lack of market-driven opportunities, bamboo-specific training among foresters, data on economic contributions of bamboo, and regulations or guidelines to support existing laws have prevented effective management of the bamboo resource. There are multiple bamboo management approaches that open economic opportunities for SSEs in the region. There needs to be more clarity on how to secure land use rights over bamboo forests, accessible financing, market linkages, business training, and low-tech/low-cost technologies to encourage the development of bamboo SSEs.

Abstract:

Spider mites, especially members of Schizotetranychus represent a common and dominant group of bamboo pests, enjoying worldwide distribution. The present paper highlights the feeding attributes of a notorious species of bamboo spider mite, viz. Schizotetranychus schizopus (Zacher, 1913) infesting the Indian Thorny Bamboo, Bambusa bambos (L.) Voss. Observations on feeding behavior of the mite were completed in the laboratory by collecting mite specimens from infested leaves of bamboo plants grown in Calicut University Botanical Garden. The species showed initial colonization on the abaxial surface of bamboo leaves, adjacent to the midrib and feeding activity of the members of the colony resulted in the development of damage symptoms like chlorotic spots, white patches, yellowing etc. Comparative analysis of the biochemical constituents of mite infested and uninfested leaves of B. bambos revealed significant alterations. Mite infested bamboo leaves presented significantly reduced values of chlorophyll fluorescence (30.10% loss in Fv/Fm ratio) thereby indicating a decline of photosynthetic efficiency. Significant reduction in total carbohydrate (58.87%) and total protein (21.02%) contents also could be accounted in mite infested leaves. Meanwhile, mite infestation was found to enhance the production of stress compounds such as Total Phenol (22.86%) and Proline (69.05%). An increase in the uptake of micro and macronutrients like Potassium (18.87%), Calcium (36.66%), Copper (48.76%) and Zinc (19.62%) was also observed in mite infested leaves. Despite this, the uptake of nutrients such as Phosphorus (8.22%), Magnesium (3.55%), Sulphur (1.54%), Iron (11.46%), Manganese (13.64%) and Boron (30.09%) significantly decreased owing to mite infestation. Significant decrease in moisture content also was evident in the mite infested bamboo leaves. The results of the study helped to evidence the biotic stress induced by the mite on its bamboo host, by promoting enhanced production of Total Phenol, Proline, Potassium, Calcium, Copper and Zinc which would play a substantial role in the defense mechanism of the plant.

Abstract:

The trend of sustainable development has been followed more globally nowadays. There is an urgent need for ecological friendly construction materials in China since the use of concrete produces pollution and leads to inefficient use of energy. Bamboo can effectively address the sustainability trends due to: lightweight construction, little adverse impact on the environment, and anti-seismic properties. However, bamboo products utilization has been very limited. Therefore, the purpose of this study was to investigate the feasibility to further utilize bamboo products in the construction industry in China. A review of engineered bamboo products utilization in China, and oversees was conducted. Based on this, a survey focusing on the current situation and suitability of bamboo products was carried out to study their feasibility, and preliminary testing on bonding shear strength for different configurations are presented. The results are promising, in particular the relatively low clamping pressure of 0.6 MPa seems to be sufficient for bonding, and it is clear that engineered bamboo products have a great potential in China. However, further more comprehensive studies on the performance of the laminated bamboo are needed.

Abstract:

In order to find out the potential effect of ammonium sulfite pretreatment on bamboo for efficient enzymatic saccharification, various ammonium sulfite loadings were conducted to pretreat bamboo at 180 °C for 1–8 h with the solid–liquid ratio of 1:6, respectively. The results verified that ammonium sulfite pretreatment could effectively disrupt the recalcitrance of bamboo and create highly enzymatic hydrolysis sugar yield for further utilization. The contents of lignin in the substrates decreased significantly (from 22.94% to 1.21%) after pretreated and the higher lignin removal with higher chemical loading and longer reaction time during pretreatment. The cellulose-to-glucose conversion yield of pretreated bamboo substrates could achieve almost 100% within 48 h by enzymes loading of 15 FPU of cellulase and 30 IU of β-glucosidase per gram glucan. Therefore, ammonium sulfite pretreatment is argued to be a potential alternative technology for pretreatment of bamboo.

Abstract:

AbstractIn South American temperate rainforests, five endemic understory birds (four Rhinocryptidae and one Furnariidae) are often associated with the main understory plant, the native bamboo Chusquea valdiviensis (Poaceae: Bambusoideae). We studied the effects of bamboo cover on species abundance and richness of those understory birds and explored the functions of bamboo as food resource and escape cover. In Chiloé Island (42°S), southern Chile, we selected four old-growth forest patches >100 ha and in each patch conducted bird surveys in six plots with >70% understory cover. Three plots were dominated by native bamboo and three plots had a sparse bamboo cover. Bird abundance (point counts) was significantly correlated with both total understory cover and percentage of bamboo cover but was not correlated with other kinds of understory plant cover. Bird species richness was positively correlated with bamboo cover and negatively correlated with other kinds of understory cover but unrelated to total understory cover. Leaf-gleaners Magellanic Tapaculos (Scytalopus magellanicus), Ochre-flanked Tapaculos (Eugralla paradoxa), and Des Murs's Wiretails (Sylviorthorhynchus desmursii), and the ground-gleaner Chucao Tapaculos (Scelorchilus rubecula) were more abundant in high-bamboo plots; but the ground-gleaner Black-throated Huet-huet (Pteroptochos tarnii) was recorded more times in plots with low-bamboo cover.Availability of invertebrates per unit of understory dry mass did not differ between high- and low-bamboo plots; but plant biomass was greater in high-bamboo plots, so total invertebrate abundance per plot was higher there. Ground-litter invertebrate abundance was similar in all plots. To examine escape-cover preferences, nine captured Chucao Tapaculos were released in front of two different understory scenarios (high-bamboo cover or bamboo-free understory); 88% of released birds moved into bamboo cover. We suggest that the structure of native bamboo understory is critical for the maintenance of four of those species, and retaining bamboo cover in managed stands may help minimize the effect of logging on understory birds.

Abstract:

This paper experimentally investigates the properties of unprecedented new advanced composite structural members in compressions made of bamboo culms formed with different bio-based and synthetic matrices. Due to extensive CO2 emissions corresponded to the production of construction materials, it is essential to produce high-performance environmental-friendly construction materials from bio-based renewable resources such as bamboo. However, the use of bamboo culms in construction has been hindered by their inherent specific geometric hollow shape. To address this issue, small-diameter bamboo species were used in this study to form solid structural composite cross-sections to desired shapes. An experimental study was conducted on the compressive properties of six composite structural members made of commonly available bamboo species (Phyllostachys edulis or Moso) with different matrices including a bio-based furan resin, a cementitious grout, and epoxy. In order to prevent premature buckling of bamboo components within the engineered columns, and in an attempt to propose a bio-based structural column, three layers of hemp wrap where applied to provide confinement for bamboo culms. The results of the tests confirm that the bamboo-furan and bamboo-grout composite columns both have the potential to reach a remarkable compressive strength of 30 MPa. However, the bamboo-epoxy composite specimen, considering the excellent mechanical properties of the epoxy matrix, delivered a benchmark to demonstrate the potentials of bamboo-based structural sections by reaching 76 MPa compressive strength before crushing. The bamboo-epoxy composite provided new prospects for future work on the 100% bio-based versions of the bamboo-based sections with improved bio-matrices (by using bio-epoxy and improved furan resins with compatible mixes) and innovative confinement types. With the promising results of this study, there is a real opportunity of creating contemporary engineered bamboo-based structures as a sustainable replacement to the existing steel, concrete and timber structures.

Abstract:

To succeed by 2050, Malaysia visions would need to be ecologically sustainable. To align with this strategy, a mock-up unit of an-eco budget bamboo chalet is proposed and designed with the aim to provide an affordable and sustainable chalet using local sustainability features and expand the use of natural resources. A sustainable bamboo chalet requires proper initial treatments and preservation in maintaining its esthetic appearance and strength. Otherwise, it can be less durable and under certain circumstances would incur high maintenance cost to the owner. In this study, the proposed unit of an eco-budget bamboo chalet is designed and analyzed using the Staad Pro V8i software. The projection cost of the bamboo chalet in the next 25 years is studied comparatively in which involves a comparison of using a different material, i.e. concrete with the same built-up area. The bamboo chalet had a built-up land area of approximately 7.5 m x 7 m (53 m2) and is made of 95% bamboo which comprises of two different species, i.e. Bambusa Vulgaris and Dendrocalamus Asper Bamboo. The results showed that construction material of the chalet saves up to 18% more when using bamboo compared to concrete. However, the total projected cost of the chalet for the next 25 years by using bamboo was 14% higher compared to concrete. Therefore, emphasis on the usage of bamboo for long-term strategy is required to maintain and control the gradual trend cost incurred if green building is to be built in Malaysia.

Abstract:

Taiwan has an abundance of the environmentally-friendly resource bamboo, as well as long-standing Chinese bamboo customs and culture. As a result, modest bamboo furniture accompanies the simple life of Taiwan’s residents. However, as people prosper, consumers are beginning to choose bamboo furniture for its decorative design and style more than for its practicality. Therefore, the symbolic application of decorative art is worthy of research and discussion. The purpose of this research is to use codes to explore the decorative design of bamboo tube furniture and enlighten Taiwan’s new direction of bamboo furniture design in the future. Through literature content analysis, field expert interviews, and practical experience participation methods, in addition to using function codes, emotion codes, transmission codes, and identification codes to interpret the Han Dynasty’s Liushu and Chinese bamboo cultural content, we verify the relevance of the code and bamboo furniture decoration and provide interactive new thinking and creative products.

Abstract:

Giant pandas ( Ailuropoda melanoleuca) are specialist feeders, dependent upon bamboo as their main dietary resource. Due to the difficulty of many captive facilities to meet the natural qualitative diet changes in bamboo species and plant parts consumed seasonally by giant pandas, it is important to understand the nutritional quality of this forage and the differences among plant parts for improved husbandry. Near infrared (NIR) reflectance spectroscopy has been used as a tool to measure forage quality for both domestic and free-ranging species. The objective of this study was to determine the capability of NIR spectroscopy to: (1) discriminate between bamboo parts, (2) discriminate between bamboo species and (3) to predict the nutrient composition of bamboo. All bamboo samples were received from the Memphis Zoo Bamboo Farm (Memphis, TN, USA), dried at 60°C and ground to pass through a 1 mm screen before analysis. Discrimination between a total of 722 branch, culm and leaf samples resulted in an R2 of 0.88 and SECV of 0.18. Spectra from a total of 756 samples of four different species were used to create a discriminant equation among bamboo species. This resulted in an R2 of 0.47 and SECV of 0.29. Validation sets were correctly predicted at the following rates: (part) branch 94%, culm 100% and leaf 100%; (species) Phyllostachys aurea 10%, P. aureosulcata 98%, P. glauca 80% and Pseudosasa japonica 73%. Calibration equations for crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF) and organic matter (OM) were created using all bamboo samples. For each nutritional constituent, the calibration R2 values exceeded 0.96. The average SEP across all constituents was 0.21% for CP, 2.35% for NDF, 3.62% for ADF, 0.84% for DM and 0.25% for OM. NIR spectroscopy was used to predict nutrient characteristics and discriminate between bamboo plant parts and species. The inability to discriminate among bamboo species is most likely due to a close physiological similarity between at least two of the species. Results suggest that NIR spectroscopy can be used to analyse bamboo forage quality which may have applications to captive giant panda husbandry.

Abstract:

Ball milling was investigated to increase the yield of soluble dietary fiber (SDF) from bamboo powder. The extraction of SDF from bamboo powder was studied by response surface methodology. The optimal extraction conditions were: pulverization time 4.64 h, temperature 23.3 °C and ball-to-material ratio of 11.31:1 (g/g). Under optimal extraction conditions, the SDF yield was up to 6.03%. In addition, the dietary fiber prepared with superfine pulverizing showed the higher water holding capacity, oil holding capacity, swelling capacity and binding ability of two toxic cations (Pb and Cu) than that of untreated sample. SEM displayed the surface of bamboo powder pretreated by superfine pulverizing was rough and collapsed. Our results confirmed that SDF from bamboo by ball milling had high application potential and could be used as functional components of feed products.

Abstract:

Bamboo is known as a sustainable alternative for green building design, and it has been tied culturally to some regions around the world. However, bamboo’s structural strength for different design scenarios needs more investigation before it is widely adopted. Timber and bamboo have similar mechanical properties, but the latter is a repaid, renewable, sustainable, disaster-resilient system and is versatile, which has more advantages for construction purposes. Natural bamboo and its derivatives have been considered as a high-demand green and environmentally responsible alternative construction material, and this interest is increasing globally. Because of the rapid growth rate and large developing area, it is more useable than the limited timber resource. However, natural bamboo has an anisotropic and nonhomogeneous material property, which varies in multiple directions. There is limited engineering data and investigation of bamboo material and its use in and impact on construction. In this study, three different bamboo models were analyzed by Strand7; each of them had different features in structure and in the major construction material. A new model was proposed by improving the three given structures and was maximized in the mechanical capacity. Some design guidelines were proposed based on the analysis and comparison of different bamboo structures. The model will replace natural bamboo with bamboo scrimber, which is an engineered bamboo derivative that has more uniform material properties.

Abstract:

Abstract Aims Accurate estimates of bamboo biomass and net primary productivity (NPP) are required to evaluate the carbon sequestration potential of bamboo forests. However, relevant data that are important for climate change mitigation, have rarely been collected in regions outside of East Asia and India. Information on seasonal patterns of NPP and its components will enable the quantification of factors that influence the carbon balance in bamboo forests. In this study, we quantified the aboveground biomass (AGB) and aboveground NPP of five major bamboo species in northern Laos using monthly data collected over a 12-month period. Methods All live culms in 10, 2 m × 2 m plots (for one monopodial bamboo species: Indosasa sinica) and 30 clumps per species (for four sympodial bamboo species: Bambusa tulda, Cephalostachyum virgatum, Dendrocalamus membranaceus and Gigantochloa sp.) were numbered and measured at breast height. We set 10 or 20 litter traps per species to collect litterfall. Censuses of dead and recruited culms and litterfall collection were performed once per month for 12 months. Important Findings The AGB was highest in I. sinica (59.87 Mg ha−1) and lowest in C. virgatum (11.54 Mg ha−1), and was mostly below the plausible global range for bamboos (32–256 Mg ha−1). The sympatric distribution of multiple bamboo species at the study sites may have suppressed the AGB in four of the five studied species. The aboveground NPP estimates were between 3.43 and 14.25 Mg ha−1 yr−1; those for D. membranaceus (8.20 Mg ha−1 yr−1) and I. sinica (14.25 Mg ha−1 yr−1) were comparable to mean global estimates for temperate evergreen forests (8.78 Mg ha−1 yr−1) and tropical moist forests (10.56 Mg ha−1 yr−1). High culm recruitment rates (15.20–23.39% yr−1) were major contributors to aboveground NPP estimates. Seasonal patterns of aboveground NPP were largely influenced by the phenology of the new culms. In the four sympodial bamboo species, new culms began to emerge following the onset of persistent rainfall, mainly in July and August. However, the sprouting of new culms in the monopodial species I. sinica followed a trend of increasing temperatures, mainly in March and April. Thus, our results indicate that bamboos have considerable potential for sequestering carbon in northern Laos, but that this potential may be affected by climate change.

Abstract:

Bamboo is emerging as a lightweight, versatile and renewable material that is projected to realise new methods of construction. There is a growing demand for using bamboo in different regions across the world. However, there are no specific design standards or guidelines that capitalise on the unique circular hollow cross section and internal nodal support of bamboo. Furthermore, there has been no strict analysis into how the curvature of bamboo members can help to better distribute stress through a structure. Bamboo is known as a more environmentally sustainable material than standard timber; however, due to the naturally occurring diaphragm nodal structure, it is less orthotropic in mechanical behaviour, with more out of plane stiffness than timber. To address this issue, this paper presents finite element analysis of three varying bamboo structures, each featuring a varying member curvature and lateral support system. In this paper, a preliminary set of design guidelines have been proposed for bamboo members, maximising the performance of its inherent mechanical properties. These guidelines propose the use of thick, low diameter bamboo members in axial loading and thin, high diameter members in flexural situations. Where available, the preliminary guidelines introduce the importance of curved bamboo members to uniformly distribute forces and crossing arched members to eliminate the need for lateral support systems, thereby reducing the total material required for construction. Finally, this report presents some novel consideration of the out-of-plane buckling of curved bamboo members–although for this purpose it does not consider the effect of the diaphragm components of bamboo, a source of future research and more comprehensive design guidelines.

Abstract:

Construction materials are selected based on two factors: structural integrity and economy. However, there is an emerging issue with regards to building materials, and that is sustainability, which considers the environmental load of a construction material. Bamboo’s lightweight and flexibility make it a good alternative for residential construction in seismic. In this study, bamboo was tested for its material properties. Layered tensile tests and full-culm compressive tests were done to get the material properties of the bamboo. The top part of the bamboo culm recorded the highest tensile strength per layer, with its outer layers having tensile strength as high as 600 MPa. The tensile strength of its middle and inner layers, on the other hand, were approximately 450 MPa and 180 MPa, respectively. As for the compressive strength, the top part of the bamboo culm recorded the highest compressive strength with an average of 76.84 MPa. The middle part of the bamboo culm recorded the lowest compressive strength with an average of 62.55 MPa. The bottom part of the bamboo culm recorded an average compressive strength of 69.49 MPa. These properties were then used to construct an orthotropic material model and simulate the stresses using finite element modeling. The FEM model of a simply-supported beam with a concentrated load at midspan was made. To validate the orthotropic material model for bamboo, three-point bending tests of bamboo beams were conducted and compared with the simulation results. The results show that in modeling the material properties of the bamboo to check for deflections, the orthotropic model gives more accurate results.

Abstract:

The African region has untapped bamboo resource potential with immense socioeconomic, cultural, and ecological significances. Despite the long history of bamboo in the region, its contribution is at the infant stage. Therefore, the present study aimed at reviewing the existing literature supported by research experience on bamboo resource in the region. The review process mainly focused on four main specific objectives. These include (1) review extensively African countries that owned the resource and identify the species in each country, (2) identify and document species, generic, and taxonomic tribes of each bamboo species, (3) assess and report bamboo area coverage from available nations, and (4) highlight the existing experiences of special opportunities, challenges, and successful achievements on bamboo resource in representative African countries. The review process found out that a total of 4.56 million ha total bamboo area and 115 bamboo species are reported from 48 African countries. Hence, the African region shares 12.3% of the global bamboo resource and contributed 7.3% of the total bamboo species. Of this, 89.6% of the region is endowed with indigenous bamboo species. Among indigenous species, O. abyssinica is the most widely distributed in 38 African countries. Madagascar ranked first with 37 indigenous species, while Ethiopia led by 25 introduced bamboo species. Nowadays, Ethiopia has 1.44 million ha total indigenous bamboo area coverage, which accounted for 31.6% of the African region and 3.89% of the world total. Therefore, more detail and comprehensive research on species taxonomy, resource base inventory, silvicultural applications, and socioeconomic study is recommended.
