Although forest conversions have long been a focus in carbon (C) research, the relationship between soil erosion and the dynamic change of soil organic carbon (SOC) has not been well-quantified. The objective of this study was to investigate the effects of converting CBF (coniferous and broad-leaved mixed forests) to economic forests, including CF (chestnut forest), HF (hawthorn forest), and AF (apple forest), on the soil structure and nutrient loss in the Huaibei Rocky Mountain Areas, China. A 137Cs tracer method was used to provide soil erosion data in order to quantify the loss of aggregate-associated SOC. The results showed that forest management operations caused macro-aggregates to decrease by 1.69% in CF, 4.52% in AF, and 3.87% in HF. Therefore, the stability of aggregates was reduced. The SOC contents in each aggregate size decreased significantly after forest conversion, with the largest decreases occurring in AF. We quantified the loss of 0.15, 0.38, and 0.31 Mg hm−2 of aggregate-associated SOC after conversion from CBF to CF, AF, and HF, respectively. These results suggest that forest management operations have a negative impact on soil quality and fertility. CF has better vegetation coverage and less human interference, making it more prominent among the three economic forests species. Therefore, when developing forest management operations, judicious selection of tree varieties and appropriate management practices are extremely critical. In addition, measures should be taken to increase surface cover to reduce soil erosion and achieve sustainable development of economic forests.

Forest Management in Java is carried out by Perum Perhutani, which has implemented a Community-Based Forest Management (PHBM) system. Pringapus Kecanatan has a State Forest which is quite extensive, however, most of the population around the forest is still in poor condition. The condition of the community around the forest in Pringapus District is illustrated by the people who do not have independence, do not have access to use the forest, the level of education and skills are still low. In an effort to overcome all this, Perum Perhutani is empowering the community in Pringapus District through the Community Forest Management System. This system is considered quite strategic because it is very accommodating to the interests of various parties including the community as the agents of development. This study aims to evaluate the implementation of the Collaborative Forest Management System (PHBM) from the Institutional aspect, the Empowerment aspect, the Agribusiness aspect and the LMDH Role aspect and formulating a community empowerment strategy through the PHBM. Analysis of the data used to answer the objectives is descriptive analysis, multiple linear regression analysis and SWOT analysis. The results of PHBM research in Pringapus sub-district indicate that the institution is being illustrated by the lack of realization of work programs as well as sub-optimal level of LMDH participation

The article considers modern transformations of forestry in Ukraine, including the specifics of its integration into the market environment. It is shown that the currently formed model of forest use has led to a continuous reduction of forest resources and deterioration of the quality of their structure. It is essential to revise the current model, including the forest management system. Currently, more than two thirds of the country's forest resources are available to the State Forest Resources Agency. However, due to the gradual transfer of the entire forest resource sector to market mechanisms of work, it is necessary to provide in advance to ensure its restoration, as well as the implementation of the most acceptable format of private forest use. The main result of the study is a conceptual vision of the new management structure. Due to the fact that in the future forestry will become more and more dependent on the private sector, the new management model should include exactly those tools that will be appropriate in market conditions. Currently, the State Agency for Forest Resources of Ukraine has very limited tools for such influence. The agency, when transferring the site for use, can only control the final result. However, the actual effectiveness of such control remains extremely low. In conditions when the bulk of wood will belong to private companies, it will be problematic to establish systematic monitoring in the country. That is why an effective economic and environmental mechanism of this type of control should be created in advance. Also, the transfer of forest use in the country requires early regulation of all production stages. That is, without such regulation it will be impossible to ensure proper compliance with the law. The introduction of market mechanisms for forest use should take place simultaneously with the introduction of comprehensive rules for the use of forest resources and the restoration of forest plantations. The main purpose of the article is to formulate the basis of a promising model of forest resources management in Ukraine. The problem is that now this area needs to be reformed and is in transition. The previous model of natural resource use in the country has led to a rapid reduction in the number of forest plantations.
