Salah satu hambatan untuk membentuk desa adat adalah tidak adanya pendampingan kepada masyarakat sehingga masyarakat kesulitan memenuhi persyaratan yang harus diajukan untuk mengubah status desa menjadi desa adat. Desa adat merupakan daerah otonom yang memiliki nilai-nilai asli yang dianut oleh masyarakat setempat dan bercorak sosial religius. Oleh karena itu penting kiranya mengulik kembali nilai-nilai asli dan corak sosial religius masyarakat Senduro sebagai modal menuju desat adat melalui pelatihan penggalian sumber daya lokal. Tujuan dari kegiatan pelatihan ini adalah mengidentifikasi sumber daya local yang dimiliki oleh desa Senduro, meningkatkan kualitas sumber daya masyarakat desa melalui pelatihan, melibatkan masyarakat dalam proses pembentukan desa adat melalui pemberdayaan. Metode yang digunakan dalam proses pemberdayaan masyarakat ini dengan menggunakan pendekatan PRA (Participatory Rural Appraisal). Dengan menggunakan metode ini maka masyarakat terlibat secara langsung dalam proses penggalian sumber daya lokal yang dimiliki oleh desa. Identifikasi awal dari kegiatan pelatihan, tim penggali sumber daya lokal desa yang terdiri dari karang taruna, tokoh masyarakat dan pemerintah desa antusias dan mampu menangkap materi pelatihan dengan baik. Hal ini dapat terlihat dari proses diskusi dan tanya jawab antara peserta dan fasilitator. Hasil kegiatan pelatihan ini secara keseluruhan dapat dikatakan berhasil karena tim yang terlibat dalam penggalian sumber daya local mampu mengidentifikasi, menarasikan hasil temuannya dalam bentuk tulisan atau catatan.

Published: September 2022

The Nevado de Toluca Flora and Fauna Protection Area presents a constant fragmentation of its forests. The objective of the research was to identify the processes of forest deterioration and the role of local stakeholders in its conservation. Geographic information systems were used as a basis for the generation of thematic maps, in addition to the application of a ﬂow diagram that deﬁnes the problems of the forest and another that describes and analyzes them for the search of solutions. The results show that the main factors affecting deterioration are forest fires, immoderate logging, pests and diseases. Finally, strategies and scenarios for forest management are proposed based on the articulation of local stakeholders.

Nothofagus pumilio forests constitute the most economically important forest stand in southern Argentina and Chile. Total volume stocking and volumetric yield vary according to site quality, degree of occupation, growth stage and forest history of the stand. The objective of this work was to evaluate the stocking and the productive potential in quantity and quality of products for the sawmilling industry, using three harvesting systems (short logs, long logs and complete shafts) in the protection cut of a N. pumilio forest of site quality III in Tierra del Fuego (Argentina). The trials were conducted in an irregular mature forest with two strata and abundant regeneration (3.0 ha; RDI 93.8–113.4%). Total volumes varied between 726.5 and 850.3 m3∙ha-1, with a volume/basal area ratio of 11.8 to 12.1 m3∙m-2. The harvesting rates obtained were: 45.5% for complete logs, 21.3% for long logs and 22.4% for short logs. A model was used to estimate the timber volume for each system, where full shafts resulted in a significant increase in timber volume. Considering new alternatives in the planning of harvesting in forest management for N. pumilio forests, such as the system of complete shafts, allows obtaining higher harvesting rates, increasing the benefits for the forestry company and minimizing the damage to the forest, due to the shorter distance of the machinery in the forest harvesting.
The population characteristics of Lithocarpus polystachyus in natural secondary forests under different human disturbance intensity
Authors: Liu Jingzao 
Published: September 2022

In November 2018, the sample plot survey method was used to analyze the population characteristics of Lithocarpus polystachyus in the natural secondary forest with different disturbance intensity in Jianning, Fujian Province, and compile its population static life table. The results showed that the number of individuals in the population was small, but it was clustered. With the increase of interference intensity, the first and second age seedlings and young trees decreased. The population types affected by human disturbance are all lacking level V trees, and the population type belongs to primary population (N1); The undisturbed population lacks level I and II seedlings and young trees, but there are level V trees, and the population type belongs to medium decline population (S2). In general, all populations of L. polystachyus are unstable and belong to the transitional type. In the static life table, the mortality of level I and II seedlings and young trees is high, the survival rate has a small peak in level III and IV, and then the survival rate decreases rapidly, and the average life expectation of level II is the highest. It shows that artificial conservation measures and appropriate space re-lease are needed to maintain the stability of the population.

Progressive fragmentation and loss of natural forest habitat in one of the world’s biodiversity hotspots
Authors: Otavo Samuel , Echeverría Cristian 
Published: September 2022

Knowledge of the state of fragmentation and transformation of a forested landscape is crucial for proper planning and biodiversity conservation. Chile is one of the world’s biodiversity hotspots; within it is the Nahuelbuta mountain range, which is considered an area of high biodiversity value and intense anthropic pressure. Despite this, there is no precise information on the degree of transformation of its landscape and its conservation status. The objective of this work was to evaluate the state of the landscape and the spatio-temporal changes of the native forests in this mountain range. Using Landsat images from 1986 and 2011, thematic maps of land use were generated. A 33% loss of native forest in 25 years was observed, mainly associated to the substitution by forest plantations. Changes in the spatial patterns of land cover and land use reveal a profound transformation of the landscape and advanced fragmentation of forests. We discuss how these patterns of change threaten the persistence of several endemic species at high risk of extinction. If these anthropogenic processes continue, these species could face an increased risk of extinction.

[Objective] To understand the relationship between species diversity and tree growth in natural secondary forests in Northeast China, to determine the reasonable size of species diversity, and to carry out appropriate nurturing harvesting and artificial replanting, so as to provide a scientific and theoretical basis for secondary forest management and management. [Methods] A total of 123 sample plots were set up in the Xiaoxinganling (XXAL), Zhangguangcailing (ZGCL), Laojialing (LYL), Changbai Mountain (CBS), Hadaling (HDL) and Longgang Mountain (LGS) areas in Northeast China, they were used to investigate the species composition, importance value, diversity and tree growth in each area. [Results] A total of 48 species belonging to 17 families and 31 genera were investigated in all the sample plots, among which the sample plots in Longgang Mountain contained the largest number of families, genera and species, followed by Hada Ling, Changbai Mountain, Laoyaling, Zhangguangcai Mountain and Xiaoxinganling. The α-diversity index of species in the sample sites was the largest in Changbai Mountain and the smallest in Xiaoxinganling, and the difference between them was significant (P < 0.05), while the richness index was the largest in Longgang Mountain and the smallest in Xiaoxinganling. The difference between them was significant (P < 0.05), while the greater the difference in latitude between the regions, the more obvious the difference in β-diversity index of species in the sample sites, and the fewer species shared between the two regions. The higher the rate of community succession, the higher the average diameter at breast height and the average tree height in each region were CBS > LYL > LGS > ZGCL > HDL > XXAL. The largest breast tree species in each region was Mongolian oak in Changbai Mountain with a diameter at breast height of 64.8 cm, and the smallest breast tree species in each region was Tyrannus sylvestris in Longgang Mountain with a diameter at breast height of 4.0 cm. The highest tree species in each region was Liriodendron sylvestris in Longgang Mountain with a height of 28.9 m, and the smallest species is yellow pineapple with a height of 1.3 m in Longgang Mountain. [Conclusion] Within a certain range, species diversity has a facilitating effect on the average diameter at breast height and average tree height of species within a stand. Therefore, during the management of secondary forests, appropriate nurturing harvesting and artificial replanting should be adopted to ensure reasonable species diversity in the stands and provide optimal space for the growth of natural secondary forests.

Published: September 2022

Objective: To study the growth, accumulation and soil nutrient content of each overseeded species under different interharvesting intensity treatments of Eucalyptus, and to explore the best re-cultivation method suitable for mixed overseeded species after Eucalyptus interharvesting. Methods: In Guangxi state-owned Qipo forest, Eucalyptus tailorii with different planting densities (DH32-29) were mixed with Castanopsis hystrix, Mytilaria laosensis and Michelia macclurei, and four different treatments (CK, LT, MT and HT) were established for re-cultivation of Eucalyptus near-mature forests with different logging intensities, and the differences in growth conditions and soil physicochemical properties of each species were analyzed. Results: (1) As the proportion of Eucalyptus allocation decreased, the growth of Eucalyptus diameter at breast height, tree height and individual wood volume could be promoted; the growth of the three parameters of HT and MT Eucalyptus were significantly different from LT and CK. (2) The average wood volume per plant of the set species in the CK and LT treatments was Mytilaria laosensis > Michelia macclurei > Castanopsis hystrix, while in the MT and HT treatments it was Mytilaria laosensis > Castanopsis hystrix > Michelia macclurei. (3) The differences in soil aeration, total saturated water holding capacity, capillary water holding capacity, and field water holding capacity in soil layers of different depth varied. In the same soil layer, soil aeration, total porosity and capillary porosity were HT > CK > LT > MT; saturated water holding capacity and capillary water holding capacity were HT > CK > LT > MT, while field water holding capacity was CK > HT > LT > MT. (4) Organic matter, pH, total nitrogen, total phosphorus, total potassium, fast-acting nitrogen, fast-acting phosphorus, and fast-acting potassium changed with varying soil depth in each treatment.

Published: September 2022

Abstract
Under the background of the marketization of agricultural products, the lack of farmers’ risk analysis mechanism has resulted in a structural imbalance between the supply and demand of funds in rural areas. The increase of the rural economy is significant to social development and stability. Then the article uses the ordered Probit model to carry out statistical regression analysis on the rural economic samples. The study found that the lack of supply institutions, the incompatibility of loan supply and demand, and the single type of insurance caused the development of the rural economy to be limited.

Published: September 2022

Abstract
This paper introduces a method for dynamic loading of human-vehicle powertrains during dangerous driving. At the same time, this paper establishes a performance evaluation index of the human-vehicle (electric vehicle) powertrain system based on the second derivative functional. We have analyzed and established the calculation formula of the excitation force of the electric vehicle drive train in unstable driving conditions. We use the numerical solution method to perform the dynamic model simulation calculation on MATLAB. The study found that the high-frequency excitation force increases the amplitude of the acceleration power spectrum of the electric vehicle system. At the same time, the research results prove that the state-space model of the electric vehicle vibration system and the selected parameter values are effective.
Facilitating Creativity through Multimodal Writing: An Examination of Students’ Choices and Perceptions
Authors: Allagui Besma 
Published: September 2022

AbstractCreativity has long been central in multimodal writing. Unlike traditional writing, which uses text alone, multimodal writing relies on the use of a combination of modes to convey meaning such as text, speech, images, audio, gesture, and space. Scholars of multimodal writing stressed that using multiple modes allows for greater creativity and newness. Recently, however, scholars have questioned whether creativity is so straightforward in students’ multimodal writing. Students may resist producing new types of writing. Their creativity outcome is dependent upon their preferences and their goals in the writing assignment. This article examines students’ choices when given the freedom to compose in any mode and their perceptions of their multimodal writing experience in comparison with traditional essay writing. Drawing on data from students’ multimodal products, surveys, and interviews we show how students simply used available resources in their multimodal composing and how creativity was negotiated. Although they identified several affordances for multimodal writing and described it as more interesting than conventional essay writing, they seemed to resist incorporating a variety of semiotic resources into their projects because their goal was to showcase their writing skills. We argue that developing explicit knowledge about various modes helps improve students’ understanding of multimodal writing as creative design.
