    Economic contribution of the forest sector is commonly downplayed by only considering its direct impacts while overlooking the ripple effects on other sectors of the economy. This lack of recognition often puts the forest sector in a less favorable position in developing national development strategy and impedes unlocking the sector’s full potential towards sustainable development. This study used three case studies (Finland, Malawi, and the United States of America) to illustrate how the forest sector contributed to national economies through direct, indirect, and induced effects. It identifies and quantifies how the forest sector is linked to other sectors of the economy via backward and forward linkages, and compares the structure of the sectoral linkages across the three studied countries. A structural path analysis approach based on social accounting matrices was used for the analysis. The forest sector was found having a promising potential to contribute to national economies through direct contribution and pathways via other sectors. The forest sector’s indirect and induced effects were found higher than its direct effects in terms of employment, valued added, and labour income. Wood-based processing subsectors in general had higher economic multipliers than the forestry and logging subsector. The real estate, wholesale trade, and food sectors were among the top backward-linked sectors of the forest sector and the construction sector was among the top forward-linked sectors for all three countries. There were great variations in how the forest sector interacts with other sectors among the studied countries. Stage of development, resource endowments, forest tenure, geo-economics, positions in international trade, and national forest policy all played some roles. The results can advance our understanding of the sectoral linkages of the forest sector in national economy and provide thoughts on how to weave the forest sector into national development strategies in a holistic way.

    Despite widespread acknowledgment of the importance of forests to sustainable development, tackling deforestation remains a herculean task. Local participation has been suggested to guarantee success in the conservation of forests and associated biodiversity. However, awareness and knowledge level of residents of forest- dependent communities on the subject is essential to their meaningful participation in forestry development in Nigeria. This chapter reports the knowledge of, attitude to and perception on forest conservation among residents of Olorunsogo LGA, Oyo State, Nigeria. Multistage stratified randomly sampling technique was used to collect primary data from 211 residents through the use of structured questionnaire. Data collected were analysed using descriptive and inferential (Chi square and Logit analysis) test statistics at α0.05. Awareness of residents about the impact of forests on the environment was high and their perception of forest conservation was guided by their knowledge of it. The latter was however low. Also, planting of trees among respondents is not dependent on their demographic background but their involvement in conservation practices is a function of their gender, educational background and marital status. Respondents’ interest in conservation will improve, if their knowledge base on the subject is built. Keywords: Forest communities, Perception of conservation, Attitude to forests ID: 3486851

    The increasing demand for timber and non-timber products from native forests in Chile and the cattle grazing has augmented the rate of degradation of these ecosystems. This process results in the need to know which of the dynamic variables are involved in its regulation. Soil quality indicators like soil organic carbon (SOC), soil microbial respiration (SMR), microbial biomass carbon (MBC), potential net N mineralization (N-min), and nitrification (N-NO), soil aggregates, and light fraction (LF), were evaluated at two different depths of the soil in Nothofagus obliqua (deciduous) and mixed N. dombeyi - N. obliqua (evergreen-deciduous) forests, where a 30- ha silvopastoral trial was established, after this evaluation, in early 2016. The SOC, SMR, MBC, N-min and N-NO were significantly higher in the N. obliqua forest than the mixed forest, 8%, 17%, 17%, 40%, 20%, respectively (p<0.05). The dry weight in soil fractions did not present differences between forest types. C and N contents in the LF (labile, un-decomposed organic matter of plant origin) were higher in the deciduous forest, 9% and 20%, respectively (p<0.05). Our results suggest that soil quality was favored by the quality of organic matter in the site dominated by deciduous species, which translates into more favorable conditions for the activity of microorganisms, nitrogen dynamic, and C and N content in the light faction. The intrinsic characteristics of the plant residues associated with higher rates of decomposition, can stimulate the activity of the biota and especially the soil microorganisms, which would lead to higher values of the different indicators evaluated. This novel silvopastoral system will likely help restore the most degraded sites through improvement of the soil quality. This kind of information allows obtaining knowledge of the forest areas and their sustainability, mainly for the planning of long-term, durable silvopastoral practices.
