“…Cameroon's forests contain more than 300 species, of which about 80 are currently exploited commercially [84,85]. In addition, local timber resources are the second largest export product after oil and contribute about 2.7% of the country's gross domestic product [86][87][88]. The turnover of the individual artisanal sawmilling sector on the national market and the markets of neighboring countries is approximately 98 606 320.80 $, while that of the community artisanal exploitation is estimated at approximately 1 535 924 $.…”

Wood plays a major role in the production of furniture and wooden structures. Nevertheless, in this process, the massive use of adhesives and plural connectors remains a definite problem for health and the environment. Therefore, wood welding is a breakthrough in this respect. This paper reviews the applications of wood welding in furniture and construction and then examines advances in improving the durability of welded wood against water. Our contribution also highlights the need to join African tropical woods using the rotational friction welding technique. According to our results, these woods present interesting chemical singularities, which could provide solutions to the water vulnerability of the welded wood. Moreover, the use of such a joining method would first free the Cameroonian furniture industry from the chemical industry, secondly position it at the forefront of new eco-design trends and thirdly make it competitive with other countries in the Central African sub-region. These works enrich the long and rich bibliography on the technique of wood welding, which has long been conspicuous by its absence of tropical woods.

Termites are one of the major pests of wood and the use of synthetic insecticides in the control constitutes a major challenge to environmental health. This study assessed the level of damage on the wood of four Eucalyptus species on exposure to subterranean termites using preference and non preference tests in the eld; and the e cacy of different plant oils to protect wood damage. Physical properties responsible for wood resistance were determined using standard procedures. Pearson correlation, Analysis of Variance (ANOVA) and Tukey's Honestly Signi cant Difference (p < 0.05) were used for data analysis. The results showed that the highest and lowest wood damages were recorded in Eucalyptus tereticornis and Eucalyptus cloeziana, respectively throughout the period of observation in Samaru-Zaria and Afaka, Kaduna. The results also showed that wood of E. cloeziana was harder than that of E. tereticornis; and correlated signi cantly with the percentage wood loss. Solignum, a synthetic wood protectant, reduced wood loss to termite infestation more than the plant oils. Oil extracts from neem seed, Jatropha seed and palm kernel signi cantly reduced wood loss than in the control treatment. However, the potency of these plant oils reduced with time. The wood of E. cloeziana demonstrated high level of resistance against termite infestation; and neem oil, Jatropha oil and palm kernel oils can be used as wood protectants as alternatives to synthetic wood preservatives.
