They also play a crucial role in supporting human life due to their environmental significance. Several bamboo species are difficult to classify manually using traditional methods. Due to the subtle differences in anatomy, their visual identification requires much field experience and expertise. This raises challenges for visual identification and suggests that the use of modern technologies could help with their identification. Accurate identification would assist in choosing the appropriate species for cultivation and would help ensure the appropriate species for various end-use applications. In this study, deep learning (DL) and machine learning (ML) were used for the automated identification of bamboos growing in nurseries. We created a bamboo image dataset comprising of 800 plant images and 4000 augmented images. These were categorized into four distinct species. We used transfer learning methods with and without image augmentation. The results revealed that DenseNet121, VGG16, VGG19 and MobileNetV2 could identify plants with an accuracy of 80.83 %, 82.92 %, 84.17 % and 76.67 %, respectively, without augmentation and with 83.37 %, 95.87 %, 96.37 % and 88.12 % accuracy, respectively, with augmentation. We introduced a Classifusion approach to classification which resulted in an accuracy rate of 97.37 % for augmented images.

Bioenergy has become one of the viable alternatives for fossil-based energy sources and a prominent part of the global energy mix. We review the application of bamboo as a feedstock for the generation of various forms of bioenergy. We give an overview of the global market size, cultivation, harvesting, pretreatment techniques, properties and characterization of bamboo as a promising lignocellulosic biomass for bioenergy production. The processes for the conversion of bamboo into pellets, briquettes, biochar, bioethanol, biooil, biobutanol, syngas, biogas and biomethane are highlighted. The deployment of bamboo as feedstock for bioenergy generation is cost-effective, sustainable, ensures high conversion efficiency and generates high bioenergy yield and quality. The limitations of deforestation, land allocation, water use concerns, scalability, lack of biomass bioenergy market and inconsistent policies can be solved through the institution and funding of more novel research and the enactment of appropriate policies and regulations. Further studies into the optimization of bamboo species, process parameters, reactor configurations, development of integrated pretreatment techniques, genetic modification of bamboo, life cycle and environmental impact assessments, and sustainability will advance bamboo bioenergy research. More innovative research and development, development of academia and industry players’ cooperation, enactment and implementation of ethical, legal, and regulatory frameworks, and incentivizing the bamboo bioenergy market are recommended to ameliorate the identified challenges limiting the development of bamboo bioenergy.</div></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":"12 ","pages":"Article 100173"},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144262156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The landraces of this species are characterised by differing morphological and mechanical characteristics. Three <em>O. alpina</em> landraces in Banja district, Ethiopia, were used to investigate the effects of landraces and culm sections on the physical and mechanical properties of the culms. Nine culms from each of the three landraces were harvested to examine their physical and mechanical properties. Harvested culms were divided into three sections along the culm length, i.e., bottom, middle and top. Data were analysed with factorial two-way ANOVA and correlation tests. We conducted Tukey's honestly significant difference (HSD) test for parameters that were significant. We found an interaction effect of landraces and culm sections on moisture content and oven dry density. Culm density was highest in the top section the red landrace, followed by the top section of the black landrace, the middle section of the red landrace, the top section of the striped landrace, the middle section of the striped landrace, the bottom section of the striped landrace, the bottom section of the red landrace, the middle section of the black landrace and finally the bottom section of the black landrace. There was a significant difference in tangential and radial shrinkage between landraces and culm sections. There was also a significant interaction effect of compression strength between landraces and culm sections. The top section of the red landrace, the top section of the black landrace and the middle section of the red landrace had the highest to lowest compression strength, respectively. The effect of landrace and culm section on modulus of elasticity and modulus of rupture were significantly different.

This study evaluated the effect of different spectral qualities: fluorescent, white, blue, red and a blue:red combination in equal proportions, on the micropropagation of <em>Dendrocalamus asper</em>. The experiment was conducted using nodal segments as explants, with five replicates per treatment and 20 explants per replicate, totalling 100 explants per condition. Growth parameters such as shoot length, number of leaves and contamination were recorded. The results showed that blue:red LEDs (1:1 ratio) significantly enhanced leaf formation and shoot elongation, with an average shoot length increase of 35 %, compared to fluorescent light. The red LED treatment reduced bacterial contamination by 40 %, demonstrating its effectiveness during the inoculation stage.

However, growing threats jeopardize their sustainability. This study explored the utilization potential and threats on native highland bamboo forests in Dama District, Guji Zone, Ethiopia. Multi-stage sampling techniques were employed in selecting the study sites and 130 sample respondents. Data were collected through a combination of focus group discussions, key informant interviews, household survey and field inventories. The potential of highland bamboo forests was analyzed by examining farmers' participation in bamboo growing practices, comparing their dependency on bamboo with other livelihoods, and evaluating bamboo's contribution to overall income generation. The data were analyzed through descriptive and inferential statistics using SPSS version 24. The utilization potential of bamboo in the study area was primarily for construction, home utility, agricultural tools and other uses. Bamboo was ranked third among primary livelihoods, with about a 12 % share. Income from bamboo was compared with other sources such as livestock, crop production, tree products and off-farm activities. The average annual income from bamboo sales was 1960 birr, accounting for about 19 % of total income. A multiple linear regression model revealed that household income levels from bamboo forests was mainly influenced by land-holding size, education level, off-farm activities, bamboo planting experience, extension services, diseases, and information on bamboo production and marketing. Poor management (60 %) was the primary identified threat to bamboo forests, followed by diseases (22 %), inadequate expert support (16 %), farmland expansion (13 %), expansion of <em>Eucalyptus globulus</em> (7 %), and trampling and browsing by livestock (5 %). Native highland bamboo forests in Dama District are vital for rural livelihoods and offer high potential for various uses, but they face significant sustainability threats.
