Wood adhesive is very important to the quality of wood-based panels in the forest product industry. Researchers are currently focused on developing green and environmentally friendly adhesives using biomass materials. Soybean meal (SM), a cheap and high-protein byproduct from soybean processing, is considered a green biomaterial resource for adhesive production. In this study, SM was modified using urea and sodium hydroxide as denaturants, and two cross-linking agents were prepared to incorporate into the soybean meal adhesive for bonding reactions. Sodium hydroxide added to soybean protein caused structural damage to the protein structure, which allowed the peptide chains to unfold extensively, forming a low-molecular-weight peptide mixture with a good size distribution and exposing numerous active functional groups for cross-linking with the tannin–phenol–formaldehyde resin (TR) and wood. Adding the epoxy resin CA and TR enabled the cross-linking agents to react with the active functional groups on proteins, forming a cross-linked network structure. As a result, the adhesive's strength, residual rate, and solid content were improved. [ABSTRACT FROM AUTHOR]

Rural people living around forests in Ethiopia depend on income from forest product collection as one of their livelihood activities. The forests of Sheka are threatened by unsustainable use and conversion to alternative land uses. This study was conducted to identify and quantify income from major forest products collected from the Sheka forest and examine factors that determine income from forest product collection. Quantitative and qualitative data were collected from primary and secondary sources. By stratified random sampling method, three kebeles were selected from the Masha district and 156 households were randomly selected from those kebeles and interviewed with a structured questionnaire. Descriptive and inferential statistics were determined by SPSS and STATA software. Multiple linear regression models were employed to determine the relationship between socio-economic factors and forest income. The result indicates 17 major forest product were collected and contributes an average of $1553.75 or 41.17% of their total annual income and was the highest contributor to total income. Forest income varies with agro-ecology and distance from the nearby markets in the study area. Households in the study area utilize more forest products for home consumption. Incomes from forest product collection are significantly related to the level of education of the household head, family size, and distance of home from the forest and market. Households in the study area depend to a higher degree on income from forest product collection and have an implication of sustainable management of forests in the long term.

The Ministry of Environment is competent to adopt measures to ensure the protection of wild flora species, and to take the necessespaary measures to protect endangered or endangered species. Within this framework, it must intervene in the management, exploitation, transport and commercialization of species and individuals of wild flora and their primary products, whether public or private property. As a control and surveillance measure, the natural resources code requires that all primary forest products entering, leaving or moving within the national territory must be covered by a permit. For the mobilization of forest products, authorization documents are required, and these will vary depending on the forest products, which according to the legislation are classified as: 1) single online safe-conduct, 2) mobilization certificate and 3) mobilization remission.

The present study aimed to evaluate the physical, chemical and anatomical properties of Cryptomeria japonica wood. For that, trees with 13 years old, from an experimental planting, were sampled. The wood was classified as low density (0.314 g cm-3), with low values of longitudinal contractions (0.31%), radial (2.09%), tangential (5.48%) and volumetric (7.57%), but high anisotropy coefficient (2.62), indicating the susceptibility of this species to drying defects. Regarding the chemical composition, it presented low levels of extractives (2.14%) and ashes (0.32%), but high content of lignin (31.36%). The tracheids have 2.18 mm length; width of 25.06 µm; lúmen diameter of 15.89 µm and wall thickness of 4.59 µm, with interesting indicators for papermaking, and presenting good quality due to the Runkel index (0.61) and felting (87.78) and medium quality for flexibility coefficient (61.23%) and wall fraction (36.94%). The characteristics of C. japonica wood indicate potential to be used as alternative to supply the demand of the industrial sector for raw material, especially in the South of Brazil.

Forest is one of the most essential types of resources providing beneficial material and environmental service. The forest of Sheka is threatened by unsustainable use and conversion to alternative land use. This study was conducted to identify the major collected and marketed forest products, quantify the total and relative forest product income generated by the gender of household head in Masha district, southwest Ethiopia. Quantitative and qualitative data were collected from primary and secondary data sources. Primary data were collected through focus group discussion, key informant interview and survey consisting of 156 household samples that were selected using multi-stage sampling techniques. Secondary data were collected from published, unpublished materials and annual reports of relevant government offices. Data were analyzed using SPSS and Stata software programs. Descriptive statistics like mean, frequency and percentage were determined. The result indicates that 17 major forest product are collected by households in the area. Forest product collection is one of the livelihood activity contributing on average of $1887.16 (44% of their total annual income) and $867.3 (32% of their total annual income) to male and female headed households, respectively. This proves that, in the study area, male headed households generate more income from forest products than female headed households. Household in the study area depend to a higher degree on income from forest product collection. Alternatives should be found to minimize extraction of woody forest products and minimize dependency of household on forest income. Government should assess the impact of licensed investment project on environment and local community and take corrective action. [ABSTRACT FROM AUTHOR]

The study includes the analysis of cultural, commercial, and safety factors that affect the potential of the trade of the red sour pitaya (Stenocereus gummosus), as well as its characterization, consumer patterns, consumption channels, and the relevance, identity, and cultural value of the fruit in the Municipality of La Paz, Baja California Sur, Mexico. The investigation has the objective of understanding the perception of the product in local knowledge, which is identified in the study area, where the wild fruit takes an added value in informal commercialization and is amalgamated with the local culture. For the analysis and data collection, a simple random sampling was conducted, on 227 economically active people with purchasing power. The method of applying the instrument was digital, limiting face-to-face contact with people due to the current Covid 19 pandemic. The exercise characterizes a population with mostly university studies, which consumes the product in a traditional way, which reflected a greater appreciation of the pitaya fruit, by older people.

Abstract Wood-based industry is one of the main drivers of economic growth in Malaysia. Forest being the source of various lignocellulosic materials has many untapped potentials that could be exploited to produce sustainable and biodegradable nanosized material that possesses very interesting features for use in wood-based industry itself or across many different application fields. Wood-based products sector could also utilise various readily available nanomaterials to enhance the performance of existing products or to create new value added products from the forest. This review highlights recent developments in nanotechnology application in the wood-based products industry.

There is urgent need to rescue Nigerian economy from deluge of crisis it is been confronted with atthe present time. To achieve this, it is pivotal to explore various potentials available in the country to solve her problem. Therefore, this paper examines the potential of apiculture industry in social and economic development of the nation. Hive products such as beewax, propolis, pollen and royal jelly are known to have contributed largely to the economic development of advanced countries like China, Turkey, Mexico, Argentina, Hungary, Australia and Canada. While the practice provides job opportunities for people of all classes, it also boosts productivity of other agricultural crops. Honey from Nigeria will command higher demand and prices in the world market for its medicinal and antimicrobial qualities, thereby serving as a good foreign exchange commodity in international market. As part of its contribution to economic growth, apiculture is a good source of income for beekeepers, it involves the use of little land. It empowers small scale farmers and also does not damage the environment. The paper also stressed that apiculture is not only important for generating income, it also curbs against rural migration. Apiculture protects the environment and also an important non-timber forest product. [ABSTRACT FROM AUTHOR]

Dayak Meratus tribe is the native tribe that lives in the forest area of Meratus Mountain. Biological basic data on plant biodiversity in the area, particularly plants utilized by Dayak Meratus tribe, have not been much discovered. The research are: (1) to discover the traditional characteristic and knowledge of Dayak Meratus tribe, (2) to determine the priority of plants to be conserved, (3) to study local government policy in the forest resources management and, (4) to determine the strategy of priority plants conservation. Research was conducted at Meratus Mountain forest area, Hulu Sungai Tengah Regency and Herbarium Bogoriense, Biological Research and Development Center of LIPI, Bogor, from July to September 2002. Determination of priority plants is based on 4 criteria: (1) Index of Cultural Significance that consists of three value, that are: quality of use, intensity of use, exclusivity of use, (2) Distribution, (3) Status in the nature area (wild, semi domesticated, domesticated/cultivated), and (4) the characteristic of use/utilization by the community (commercial, subsistence). The number of plant species used by Dayak Meratus Tribe is 240 species of 18 use characteristic, 2 species endemic, 14 species rare, 111 species have more than one utilization function, 20 medicinal plants can be used as a consideration in changing the status of protected forest to conservation areas with status of national park.

Wooden housing is one of the most sustainable building alternatives. In many European and North American countries, wooden houses provide the most common, economical, and practical solution for construction. The timber buildings present adequate levels of durability, acoustics, and thermal comforts. Despite their popularity, wood houses do not have a standardized classification to define and organize their main aspects. In literature dealing with timber construction, most authors emphasize structural systems for large spans (bridges, hangars, roofs, etc.). The presence of some classifications of timber construction results in unclear issues, and few studies have covered and regarded wooden buildings as residential construction typologies. Accordingly, this paper proposes a classification that connects the aspects and details of wooden housing materials in relation to the industrialization level and chronological origin. We expect this classification to assist in a better understanding of distinct wooden housing techniques commercially produced worldwide, diffusing their concepts and possibilities as forestry-timber products.

This work analyzes the effect of forest on the economy of Central African Republic, using the data from secondary source within the period of 1970-2015. The study employed error correction model (ECM) as econometric methodology to estimate the cointegration relationship among economic growth, agriculture value added, forest rent (in percentage of GDP) and forest product variables (logs, roundwood, wood fuel and sawnwood), it also estimates long run and short run relationship between variables. Augmented Dickey Fuller (ADF) unit root test were employed. The result shows that forests play an important role in the world's economy; they support both the economic growth and the ecosystem protection. The co-integration relationship result (using Engel-Granger) shows economic growth forest products variables (logs, roundwood, wood fuel and sawnwood) and other variables included in the model were co-integrated and therefore long run relationship exist among them. Testing the short run relationship shows the existence of short run relation between variables. The long run model shows logs production which the main exportable wood product in CAR having a positive and significant effect on the economy but we noticed that the affectation percentage is to low (0.08% change to GDP). This is due to the lack of control or traceability of the product and the luck of strong institutions (corruption) in the forestry sector. [ABSTRACT FROM AUTHOR]
