“…The study obviously showed that when the financial values of timber are integrated into the model, the model overlooks some expenses like reforestation. As expected, additional constraints into management planning cause loss of volume and NPV of timber products (Raymer et al, 2005;Baskent et al, 2008b).…”

“…Liski et al (2001), however, showed that while the cumulative amount of carbon sequestered in Scots pine forest increased with increasing harvesting age it reduced in Norway spruce forest. Similarly, some researchers indicated that some silviculturel interventions such as reforestation (Krcmar et al, 2001;Baskent et al, 2008b) or afforestation (Kaul et al, 2009) particularly in early periods, cause high biomass and provide positive effects on the sequestrated carbon despite the certain amount of expenses of reforestation. However, the results indicated that total water production and NPV in different minimum harvesting ages did not follow a systematic trend observed in timber and carbon values.…”

“…As part of the ecosystems based multiple use forest carbon balance was restricted as below and above ground carbon sequestration. Merchantable volume was employed to calculate the biomass of trees using some equations (Asan et al, 2002;Baskent et al, 2008b). The carbon emissions were calculated based on the lifetime of timber assortments as suggested in the literature; 50, 40, 15 and 10 years for sawlogs, mining pole, boards, and woody debris such as fuel wood, bark and harvest waste respectively (Krcmar et al, 2005).…”

RESEARCH ARTICLE OPEN ACCESSof forest ecosystems (Christensen et al., 1996;Davis et al., 2001;Baskent et al., 2008a) In this way, the integration of water production and carbon sequestration into forest management planning becomes a significant challenge of contemporary research endeavors. Forest ecosystems cover wide range of areas on earth and as such they are one of the most important natural assets affecting the management of water resources. Therefore, forest ecosystems have significant function in the management of water resources. However, water resources in terms of quantity and quality are affected by anthropogenic activities as well as natural disturbances. Currently, the perceivable effects of climate change have raised great attention to disclose the water- Evaluation of Forest Dynamics Focusing on Various Minimum Harvesting Ages in Multi-Purpose Forest Management Planning AbstractAim of study: Exploring the potential effects of various forest management strategies on the ability of forest ecosystems to sequester carbon and produce water has become of great concern among forest researchers. The main purpose of this study is to evaluate the effects of management strategies with different minimum harvesting ages on the amount and monetary worth of carbon, water and timber values.Area of study: The study was performed in the Yalnızçam planning unit located on the northeastern part of Turkey. Material and Methods:A forest management model with linear programming (LP) was developed to determine the effects of various minimum harvesting ages. Twenty-four different management strategies were developed to maximize the economic Net Present Value (NPV) of timber, water and carbon values in addition to their absolute quantities over time. Amount and NPV of forest values and ending inventory with different minimum harvesting ages were used as performance indicators to assess and thus understand forest dynamics.Main results: Amount and NPV of timber and carbon generally decreased with extended minimum harvesting ages. However, similar trends were not observed for water production values. The results pointed out that the performance of a management strategy depends highly on the development of a management strategy and the initial forest structure aside from the growth rate.Research highlights: Minimum harvesting ages affect forest outputs under the same objectives and constraints. Performance of a management strategy highly depends on initial age class structure in addition to the contents of a management strategy.

“…The model does not explicitly describe the carbon stored or released from the soil, emissions from harvest operations, products transport (i.e., carbon emitted by trucks and machinery), product recycling, or effects of substituting fossil fuels by wood. Similar approaches were used in other forest planning works (Díaz-Balteiro & Rodriguez 2006, Baskent et al 2008.…”

We developed a forest planning model integrating two operational scales (single-stand and forest levels) for the optimization of timber production and carbon sequestration in forest teak (Tectona grandis L. f.) plantations. At the stand level, growth and yield simulations using a heuristic thinning optimizer provided a set of near-optimal thinning regimes for individual stands differing on initial spacing and site quality, given biological, silvicultural, and financial constraints. The set of near-optimal thinning regimes obtained were then used as input of the forest-level model, which generated optimal harvest plans for the whole plantation by simultaneously maximizing the net present value of merchantable wood and carbon sequestration. The net amount of carbon captured by the biomass and the emissions produced by decomposition of woody debris and timber products after harvest were estimated. The growth and yield model was based on a system of differential equations incorporating heuristics (genetic algorithms) to optimize age and intensity of thinnings. The full model can handle the optimization of harvest schedules for projects up to 10,000 ha and 200 stands and was tested on a validation dataset including teak plantations from Venezuela and other Latin American countries. Results indicated that regimes favoring carbon sequestration reduce the benefits of timber production, and equal profitability of carbon sequestration and timber production was obtained for carbon prices over 40 $US Gg -1 . Sensitivity analysis showed that the proposed model is sensible to variation in growth rates, carbon and timber prices, and production quotas, and barely sensible to harvest and transport costs. The developed model has a modular structure that allows its calibration to incorporate data from a wide range of management regimes for teak and other forest species.

Developing a decision‐making tree for circular economy

Circular economy (CE) is aimed at redressing the negative impacts on the environment from linear economic models. CE should consider the economic and environmental dimensions; however, in most cases, these have been addressed separately. CE discourses have focused mainly on the environmental dimension and assumed that all material loops must be closed. Despite the calls to engage with CE, there has been extremely limited research on decision‐making for CE. The following steps were followed in the decision‐making for CE framework construction and design: (1) reviewing the literature; (2) considering economic data approaches; (3) accounting for material flows; (4) modifying the fungibility approach to focus on the environmental dimension; (5) considering environmental impacts; and, (6) selecting a decision tree format. This paper combines the economic fungibility (probability of recovery and price), environmental impacts fungibility (probability of recovery and environmental impacts) to develop the ‘Decision‐making tree for circular economy’ framework. The decision‐making tree for circular economy is aimed at providing guidance on which and how to close loops depending on economic considerations, environmental impact, and probability of recovery of materials. The CE decision‐making tree provides eight options to help decide which and how to close such loops, and help decide which material loops should be eliminated, closed, or remain open. Decision‐making is key to deciding which loops to close to engage with CE more efficiently.
