Disempowering Traditional Spatial Arrangement of Dayak Community: A Case Study of Tumbang Marikoi Village, Central Kalimantan, Indonesia

The rapid industrialization in the last decades significantly changed the traditional spatial arrangement in Central Kalimantan Island. The indigenous community’s traditional forest lands management and ownership were transferred to oil palm plantations and mining corporations. Therefore, it disempowered the traditional spatial arrangement by changing the community’s living conditions and transforming their livelihood sources from primary (forests) to secondary and tertiary. The disempowered traditional spatial arrangement of the Tumbang Marikoi village community includes a living area with rivers, forests, and dwellings. They access the forest through the village Kahayan Hulu and the Marikoi River. There is no power grid in Marikoi Village, making them depend on a solar-powered energy generation facility for their daily activities, including gardening, gathering forest products, hunting, mining gold, and fishing. This study applied the phenomenological method to explain the traditional spatial disempowerment in Marikoi Village, Central Kalimantan, following corporate plantation powers and mining activities. The results indicated that the palm plantations affected the Dayak community's living space and daily life. Furthermore, the ownership and management of their customary land, enhancing their economic, social, cultural, and religious life, was transferred to large plantations. As a result, the community’s traditional spatial arrangement was disempowered through river silting from soil drilling, cloudy river water, flooding, distant land for income (selling honey, vegetables, rattan, herbal medicine, and other forest wealth), farming restrictions by clearing land and losing sacred areas and ancestral rituals.

Planning and Professional Assistance as Factors Influencing Private Forest Landowner Best Management Practice Implementation

Virtually all states have developed best management practices (BMPs) to mitigate potential adverse effects associated with timber harvesting. This study examined how BMP implementation on Minnesota’s family forest lands varied according to whether the land had a forest management plan, the timber sale was administered by a forester, or a written timber harvesting contract was used. Analysis of field monitoring data from 174 commercial timber harvesting sites on family forest lands found that BMP implementation is only modestly influenced by a forest management plan, supervising forester, or timber harvesting contract. Supervision of a forester had the greatest influence, with six guidelines implemented differently. In contrast, differences were found for just two BMPs with a forest management plan and only one with a written timber harvesting contract. When timber sales were administered by a forester, forest management guidelines generally related to management of the land-water interface were implemented to a higher standard, with significant increases observed for avoidance of infrastructure in filter strips, use of water diversion and erosion control structures, avoiding unnecessary wetland and waterbody crossings, and slash management. Higher timber utilization efficiency (within leave tree guidelines) was also found when a professional forester supervised the timber sale. Study Implications: We examine how BMP implementation on family forest lands varies with three types of supervisory and planning assistance: a forest management plan for the property, sale administration by a professional forester, and a written timber harvesting contract. Field monitoring data from 174 commercial timber harvests on family forest lands indicate that BMP implementation is only modestly influenced by any single form of assistance. Supervision by a forester had the greatest influence, increasing use of four guidelines related to management of the land-water interface. Results may help to inform best practices for landowner assistance and planning.

On the way to balance of forestry land use of Ukraine: ecological-and-economic aspect

Purpose. The purpose of this work is to investigate the ecological-and-economic aspect of certain factors to ensure the balanced use of forest lands; develop proposals for the formation of the basis for the development of sustainable forestry. Methodology / approach. We used the following methods: dialectical method of cognition for the analysis of scientific works of scientists concerning problems of balanced use of lands of forestry purpose; method of analogies (transfer of patterns of development of one process with certain amendments to another process or territory); statistical (based on quantitative indicators that allow drawing conclusions about the pace of the process); comparative analysis (comparison of indicators of forest resources and their use for Ukraine and Poland); correlation analysis (identification of factors on which the forecast significantly depends; clarification of relationships, their relationship with the predicted phenomenon under the influence of certain factors), graphical, abstract-logical (theoretical generalizations and formulation of conclusions). The information base of the study is the data of the Global Assessment of Forest Resources of FAO 2020, the data of the Monitoring of Land Relations in Ukraine, the reporting of the State Forest Agency of Ukraine, the data of the Forest Stewardship Council®. Based on the annual reports of the State Forestry Agency of Ukraine, some indicators of the report of 288 state forestries for 2018–2020 are consolidated in terms of 24 regional departments of forestry and hunting. Results. In the dynamics for 2018–2020, changes in the volume of forest resources, forest reserves, biomass, and carbon density were studied; the indicators of forest resources and their use for Ukraine and Poland are compared. The volumes of forest certification by regions of Ukraine are estimated. The relationships between capital investments in forestry production and the price of sold wood, the volume of net income of state forestry, the amount of profit, the degree of depreciation of fixed assets; between the tax burden on state forestries and financial stability was studied. Based on the assessment of the relationships and changes in individual indicators, the need to update the fixed assets of forest enterprises through the improvement of the investment instrument is justified. The results of this study are a summary of evidence on the environmental and economic aspects of the impact of certain factors on the sustainable use of forest lands, which in turn forms the scientific basis for achieving the goals of state environmental policy of Ukraine. Originality / scientific novelty. The studied interdependencies between the statistical characteristics of individual indicators of forestry land use made it possible to identify factors to ensure balanced use of forestry lands. It is substantiated that reforestation, forest certification, renewal of fixed assets of forestry enterprises through the improvement of the investment instrument, optimization of the tax burden of forestry activities are favorable factors to ensure the balance of forestry land use. It is proved that the excessive tax burden is a deterrent to the balanced use of forest lands. It is proposed to alleviate the tax burden on forestry activities by reducing the rate of deduction of net income of state forestry enterprises, eliminating the problem of double taxation of the forest fund, which under limited budget funding will allow state forestries to accumulate their own financial resources to ensure sustainable land use. Practical value / implications. The main results of the study can be used to: (I) structure the factors of sustainable use of forest lands; (II) defining the goals of sustainable development when developing the strategy of forestry enterprises; (III) analysis of the achievement of sustainable development goals at the national level, defined by the Basic Principles (strategy) of the state environmental policy of Ukraine for the period up to 2030. The results of the study can be used both at the level of forest management entities, as well as at the regional and national levels, to make management decisions on the implementation of measures that ensure the balanced use of forest land. Also, the causal links between indicators that arise from the response of indicators to certain factors open up new opportunities for forest management planning. These results can provide important information for the protection and use of forest resources in all regions of Ukraine.

Analysis of the Possibilities of Applying Mobile Robotic Platforms Using Machine Vision in Industry

The article considers the possibilities of automated use of robotic equipment in order to form an infrastructure for moving goods at enterprises. Areas of application of algorithmic programming languages of object-oriented type in robotics are investigated. The algorithm of operation of a transport vehicle, the movement, which is based on the recognition of the line of motion, describing the route of movement, is presented. The analysis of the peculiarities of the implementation of such problems with the use of OpenCv software library was carried out. The structure of the vehicle is proposed, in particular: its driving mechanisms, control scheme, engines and wheelbase. Further development was made to the algorithms for the management of crawler lorries and the ways of their program realization in various spheres of entrepreneurial activity, where there is a need for the transfer of cargoes in the ordinary areas (construction sites, forest lands, open warehouses, airports, etc.). Based on the proposals for creating a cargo robot that can be moved according to a given route, the model of control system of conveyor systems, which solve the issues of automation of technological processes in the part of the addition of conveyor systems, is presented. The analysis of literary sources describing the necessity of creating mobile conveyor systems in production, which enables to quickly re-equip production processes to unforeseen needs, was carried out.

Public Attitudes towards Birds and Private Forest Land Conservation

The eastern United States is dominantd by private forest lands, which are important for supporting a significant proportion of global bird populations. Here, we examine public attitudes towards bird conservation, government involvement in private lands issues, and private forest management objectives with an aim to better understand how these perceptions may shape broader attitudes about bird conservation. Data were collected using psychometric scales and a statewide web survey of the general public in Pennsylvania, USA (n = 656). Findings reveal four unique perspectives about birds and important correlations with conservation support on private lands. Respondents with positive views about landowner assistance programs often had more complex attitudes towards birds and were associated with relational and ethical perspectives about birds. We conclude that future public education efforts might cultivate in learners a more robust understanding of bird conservation if they included private forest lands values and culture in their programs.

Potential Areas in Poland for Forestry Plantation

Plantations have many advantages when compared to natural or semi-natural forests, such as shortening production cycles, the production of wood with specific characteristics, and near-market production concentrations. The intensive development of this form of industrial wood production is practiced all over the world. The wood industry in Poland struggles in recent years, with a large shortage of wood. The deficit of wood has been accumulated for several years and is steadily increasing. One of the possibilities to change this trend can be development of fast-growing trees plantations. The main aim of this study was to determine the potential of land in Poland, which could be used for the cultivation of fast-growing trees plantations. The analyses took into account the area and marginal agricultural land. The potential plantation land areas were determined for poplar cultivar “Hybrid 275” and European larch (Larix decidua Mill.). The results show a possibility to generate a considerable area that can be developed into plantations of fast-growing trees in Poland. According to the analyses carried out for the purpose of this study, with only 5% use of the sown area and 5% use of forest lands, as well as the boscage (wooded land and bushy land), it is possible to obtain approximately 0.6 MM ha of land for fast-growing tree plantations. In the case of planting 50% of these lands with larch and 50% with poplar, and if a 50% capacity of the plantation is assumed, it will be possible to obtain nearly 6 MM m3 of wood per year.
