ArticleSustainable business models of wood construction: Cases of six Swedish timber building extension projects
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Construction activities highly contribute to negative environmental impacts. These impacts can be reduced with the help of several measures, one of which is through using wood in building constructions. Sweden has a long history of constructing one or two-storey buildings made of wood and in the recent decades, there has been an improved understanding of the technical and environmental benefits associated with wood construction. The urbanization trends and population growth results in the need to renovate/extend existing buildings. Wood, having an excellent strength-to-weight ratio, opens the opportunity for “building on top” of the existing constructs. In this paper, six Swedish cases of timber building extension projects have been studied. The study aimed at presenting the sustainable business model of timber building extension projects. In sustainable business models, the focus shifts from plain economical aspects to also taking the social and environmental factors into consideration. It, therefore, takes a broader perspective over the activities of the stakeholders involved in the value chain of wood construction. A more comprehensive view over such activities, can lead to redesigning them towards waste minimization and value delivery to a wider array of stakeholders, while ensuring the economic sustainability of projects. This was achieved in this study through first, depicting the business models of these projects by identifying the main activities, resources, actors, and challenges involved in the building projects of the six cases. Consequently, a list of success factors for increasing sustainability in these business models were proposed.

DocumentSmall-scale timber plantations for rural household livelihoods: Case study of Acacia timber production and commercialization system in central Vietnam
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Rural poverty alleviation implies economic development at local levels to which forests contribute to different extents. Smallholder-managed timber plantations form the backbone of wood supply in Vietnam. Of the planted tree species, Acacia (Acacia auriculiformis x Acacia mangium) hybrid is one of the most preferred by timber growers. Yet, the contribution of these timber plantations to rural livelihoods is currently unknown.
This study explores the impacts of Acacia timber production and trade on rural livelihoods in Thua Thien Hue province, where the tree species has been cultivated widely since approximately 20 years. 300 household heads in Nam Dong and Phu Loc district were interviewed, following a stratified random sampling approach. We employed a combination of descriptive and inferential statistics to examine the contribution of Acacia hybrid timber income to household economies. In addition, three Foster-Greer-Thorbecke poverty measures and the Gini decomposition method were used to evaluate the effects of income from timber plantations on poverty and income inequality. The findings were validated in group discussions, key informant interviews and direct observations.
The results demonstrated that Acacia hybrid timber plantations accounted for 33-56% of total annual household income. However, more wealthy households benefitted more from Acacia timber income especially in case of a well-developed market. Livelihood diversification using timber production notably reduced all three poverty indices in both districts. Given its highest share of total Gini and positive marginal effect on total Gini, Acacia timber income was the main contributor to the overall income inequality. While this income source reduced the Gini coefficient by 0.7% in Nam Dong, it increased Gini coefficient by 18% in Phu Loc district. Recommendations refer to improving the contribution of Acacia hybrid timber plantations to rural livelihoods.

ArticleWildlife displacement, increase of contaminant loads downstream and surrounding superficial soil contamination are negative impacts of state roads and timber industry: a case study in Bunbury, Western Australia
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Roads are considered as the most harmful anthropic impacts, producing high contaminant loads to water, soil and subsequently, biosphere, and causing habitat fragmentation for wildlife. The forest-dependent species are more vulnerable when home ranges concentrate on remanent vegetation patches. Accordingly, this study assesses the displacement behavior of three endemic species (Trichosurus vulpecula, Pseudocheirus occidentalis, and Phascogale sp), contaminant load to the surface soil of the remanent vegetation patch and contaminant load downstream to the closest stream from a national road and a timber processing factory. The wildlife displacement data were analyzed through a linear regression model. The surface soil chemistry was determined among 25 variables: and for the water chemistry, 12 variables. The normality test for the water and soil chemistry data was Shapiro-test, t-test for means comparison, and Cohen’s d for the effect size. The trend line demonstrated a positive relationship between the distance to the contaminant sources and the fauna presence. The concentration of Ba/Ca/Ce/Cr/Fe/Nd, and Sr in soil chemistry, and the concentrations of Ca/K/Na/Rb and S, in water chemistry, had different means and large effect (p-value<0.05, Cohen’s d>0.8), evidencing accumulative and negative impacts to the environment (plan-water-soil interactions) caused by the national road, and timber industry.
