“…As highlighted by Kumar et al (2013), noise pollution is one of the major concern of communities living near to highways, road corridors and intersections. Most of the studies related to noise pollution and road barrier design were focus on a variety of differing scopes, methodologies, and approaches to deal with these costs therefore causing significant differences in results (Quinet 2004;Lee et al 2010;Sölveling et al 2011;Melemez 2013). …”

Highway construction works have significant bearings on all aspects of sustainability. With the increasing level of public awareness and government regulatory measures, the construction industry is experiencing a cultural shift to recognise, embrace and pursue sustainability. Stakeholders are now keen to identify sustainable alternatives and the financial implications of including them on a life cycle basis. They need tools that can aid the evaluation of investment options. To date, however, there have not been many financial assessments on the sustainability aspects of highway projects. This is because the existing life cycle costing analysis models tend to focus on economic issues alone and are not able to deal with sustainability factors. This paper provides insights into the current practice of life cycle cost analysis, and the identification and quantification of sustainability-related cost components in highway projects through literature review, questionnaire surveys and semi-structured interviews. The results can serve as a platform for highway project stakeholders to develop practical tools to evaluate highway investment decisions and reach an optimum balance between financial viability and sustainability deliverables.

“…Tree and forest volume may be used for planning and monitoring of forest management practices (West 2009). Merchantable stem volume is needed to evaluate trees from a timber production perspective, but may also be useful when determining compensations for timber loss due to several reasons such as road construction (Melemez 2012). Branch volume estimates, particularly for big trees that have been used for timber production, maybe useful to estimate fuelwood quantities.…”

Key message Models for quantifying tree biometric properties, imperative for forest management decision-making, including height, diameter, bark thickness and volume were developed, and wood basic density was documented for dry Afromontane forests of south-central Ethiopia. Abstract Tree biometric properties such as height (ht), diameter at breast height (dbh), bark thickness (bt), volume and wood basic density (wbd) are imperative for forest management decision-making. For dry Afromontane forests in south-central Ethiopia, models for quantifying such tree properties are totally lacking. This study, therefore, aimed at developing models for ht based on dbh, for dbh based on stump height diameter (dsh), for bt based on dbh, for volume based on dbh, ht and crown width (crw), as well as documenting wbd data. Comprehensive and representative datasets were collected from Degaga–Gambo and Wondo Genet forests. The ht, dbh and bt modelling were based on 1345 sampled trees during forest inventories, while the volume modelling and wbd documentation were based on 63 destructively sampled trees from 30 species covering 87% of the total basal area in the study sites. Weighted least squares regression was applied for modelling and leave one out cross-validation was used for evaluation. The ht–dbh and dbh–dsh models performed well (pseudo-R2 = 0.72 and 0.98), while bt–dbh performed poorer (pseudo-R2 = 0.42). Models for the total tree, merchantable stem and branches volume were developed with different options for independent variables, where pseudo-R2 varied from 0.74 to 0.98, with smallest values for the branches models The models may be applied to forests outside the present study sites provided that the growing conditions are carefully evaluated. The species-wise wbd was ranging from 0.426 to 0.979 g cm−3, with the overall mean of 0.588 g cm−3. The wbd data will be useful for building up a national wbd database and may also be included in the Global Wood Density database. The study represents a significant step towards sustainable forest management including REDD + MRV practices in the dry Afromontane forests of south-central Ethiopia.

“…According to previous research, there have not been any obvious changes in NDVI for the vast zonal vegetation types found in northeast China, and there have been no large variations in the inter-annual change of NDVI for forest vegetation types (Chen et al 2002(Chen et al , 2005Melemez 2013). We randomly selected larch, Korean pine, and deciduous forest as representatives to extract ten samples for averaging based on the NDVI data in August 1982-2009.…”

During the past century, Heilongjiang Province, the highest forest coverage province of China, has experienced rapid deforestation, with coverage decreasing by an estimated 40 %. As the important role that forest vegetation plays in oxygen production and environmental optimization, dynamic change analysis of forest and forest oxygen production has become more and more important. In this study, we examined changes in forest and forest oxygen production, as well as the impact of natural and human activities on such change in Heilongjiang Province, China. In particular, the net ecosystem productivity (NEP) of the forest was generated by the C-FIX model, and the relationship between NEP and forest oxygen production was examined. Analysis results indicate that in the past century, the forest area and oxygen production of Heilongjiang Province has been reduced by about 106,667.57 km 2 (37.16 %) and 56.22 million tons (33 %), respectively. Moreover, the spatial analysis results suggest significant spatial variation of forest oxygen production in Heilongjiang Province, China. Specifically, oxygen production in the southwest has shifted from the highest area to the lowest area, and significant decreases in forest oxygen production have been observed in the Sanjiang Plain and the central part of Heilongjiang Province. In addition, oxygen production also presents decreasing tendencies ([90 %) in Daqing City and Qiqihar. The analysis of the impact of climate change and human activities on forest oxygen production indicates that human activities have the largest impact on forest oxygen production, accounting for about 67.95 % of the decrease.
