报告题目：Perception and Potential of Species Used in the Construction of Traditional Houses in the Antsimo Antsinanana region of Madagascar

报告摘要：
Traditional housing in Madagascar vary in structure and setting, influenced by local culture, environment, and climate. However, the use of wood in traditional housing construction contributes to forest degradation in the country, as wood is readily available and frequently used. This practice is further exacerbated by illegal selective logging, which leads to the disappearance of species that have important ecological roles. The annual consumption of wood and the durability of the construction are highly dependent on the species chosen. To tackle this problem, this study aimed to identify the most commonly used species in traditional housing construction and understand the reasons behind these choices.  The results of the survey of 145 households in the Antsimo Antsinana region revealed that Cleistantopsis sp, Syzigium sp, Streblus dimepate, Carissa edulis, Eucalyptus sp, Tambourissa sp, Cleistantus boivinanus, Homalium sp, Harungana madagascariensis, Acacia sp are among the 10 species most commonly used in construction. The reasons for this choice are based on perceived durability (12.41%), strength (71.03%) and straightness (37.24%), as well as economic considerations (20.69%), with people favouring the most affordable species. Using Near Infrared Spectroscopy (NIRS) technique on samples of these 10 species, we were able to determine the physical and mechanical properties of the wood, its density and mechanical strength, as well as estimating its natural durability. The results showed that only half of the species tested matched people's perceptions. It is therefore crucial to gain a better understanding of wood's potential in order to determine people's needs based on their perceptions, and to propose alternatives with similar characteristics for the balanced and sustainable management of forest resources
