“…As the discounting rate can be reflected in the rotation period, the discounted present value assists forest owners to know what the future timber value is worth now. The optimal rotation age is the period in which the marginal yield value equals forest value returns and land value (i.e., the marginal benefit equals the marginal opportunity cost) [14]. The Faustmann formula factors the establishment cost and is based on forest management for even-aged infinite rotations, as shown in Equation (1).…”

“…As to the BEF of Pistacia chinensis, we chose to use the value from IPCC [60], which is 1.4 for the temperate broadleaf trees. µ is the carbon content in the dry mass, here µ is 0.5 [14,20]. When it comes to R, we chose the ratio of the average temperate broadleaf forest from IPCC [60] to estimate the one of Pistacia chinesis.…”

Abstract:Forests provide a range of ecosystem services, including bioenergy supply and carbon sequestration, both contributing to significant climate change mitigation. Oleaginous trees have potential to provide bioenergy supplies through biodiesel-producing seed yield as well as contributing to carbon sequestration. This paper aims to show the provisions of bioenergy and carbon savings through forest rotation management and it will investigate the potential of oleaginous forest management in China. We use the land expectation value (LEV) model to calculate the optimal joint values of timber, seed and total carbon savings, including carbon sequestration from forest and carbon reductions through energy substitutions. The results indicate that combining both values of seeds and carbon savings increase the LEV and rotation age (167,611 Yuan/ha, 78 years) compared to sole timber value (26,053 Yuan/ha, 55 years). The optimization of the LEVs and the resulting optimal rotation ages are significantly sensitive to the discounting rate. Annual biodiesel potential production from Pistacia chinensis can take up 1.7% of the national diesel consumption in China. We conclude that China can use improved forest rotation management as an effective means for achieving goals in its low-carbon energy strategy.

“…Some studies explained that when carbon prices increased, the minimum harvesting age would increase, but when timber prices increased, the minimum harvesting age would decrease (Van Kooten et al, 1995). In addition, Olschewskia & Benitez (2010) demonstrated that cost of carbon have important effect on minimum harvesting ages that may cause a doubling of minimum harvesting age in contrary to optimum 15 years when considering just wood harvest. However, very few studies are involved in evaluating both the interactions between timber harvest and carbon storage and the effects of different minimum harvesting ages on dynamics of forest ecosystems under management (Swanson, 2009;Mumcu, 2007).…”

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.

Forest plantation may contribute economically and socially as a provider of wood raw materials for industry and providing jobs ABSTRAKHutan tanaman dapat berkontribusi secara ekonomi dan sosial yaitu penyedia bahan baku kayu untuk industri dan penyediaan lapangan pekerjaan bagi masyarakat. Selain itu, hutan tanaman dapat pula berkontribusi dalam pengaturan tata air dan penyerapan karbon. Proyek perdagangan karbon untuk hutan tanaman dapat dilakukan melalui beberapa cara antara lain dengan pembangunan hutan tanaman baru di lahan terbuka ( ) dan aforestasi memperpanjang daur tebangan. Penelitian ini bertujuan untuk menganalisis daur optimal tegakan gmelina pada dua proyek karbon: memperpanjang daur dan aforestasi. Metode yang digunakan dalam penelitian ini adalah metode Faustmann yang dimodifikasi (yaitu Hartman) yaitu maksimasi keuntungan dengan sumber pendapatan dari kayu dan jasa lingkungan penyerapan karbon. Hasil dari penelitian ini menunjukkan bahwa harga karbon akan memengaruhi daur optimal tegakan gmelina pada proyek karbon VCS memperpanjang daur tebang. Sementara itu, pada proyek aforestasi VCS, tingkat harga karbon tidak memengaruhi daur optimal Faustmann. Nilai NPV proyek aforestasi relatif lebih tinggi dibandingkan nilai NPV proyek memperpanjang daur tebangan karena jumlah karbon yang dapat dikreditkan relatif lebih tinggi pada proyek aforestasi.
