Recently, Indonesian peatland has become global attention regarding several forest fire events, which are seemingly caused by the improper ecosystem management system. Through literature review, this paper discusses one of specific forest formations in peat swamp, namely ramin forest (Gonystylus spp.). An assessment is performed for ramin forest management system from time to time using a framework developed by Indonesian Eco-Labelling Organisation. The criteria applied are sustainability of production, ecological, and social functions. Several recommendation to refine ramin forests are (1) assure new concession permit in any peat swamp areas stops and (2) hasten the implementation of one-map policy as a baseline for further planning and calculating current potency of ramin. For the new regulation, activities can be carried out are (1) to rehabilitate the degraded peat-peat swamp forests, (2) to strictly protect the last pristine ramin forests, (3) to establish seed orchard from seed resources to conserve the germ plasma, (4) to support research into ramin degraded forest restoration and the ecological relationship in pristine ramin forests to better understand how the system works, (5) to recalculate the current diameter increment and to use that to calculate the harvesting rotation, and (6) to uphold forestry law more firmly.

The aim of this paper is to establish an international framework for sustainable project management in engineering, to make up the lack of research in this field, and to propose a scientific theoretical basis for the establishment of a new project management system. The article adopts literature review, mathematical programming algorithm and case study as the research method. The literature review applied the visual clustering research method and analyzed the results of 21-year research in this field. As a result, the project management system was found to have defects and deficiencies. A mathematical model was established to analyze the composition and elements of the optimized international project management system. The case study research selected large bridges for analysis and verified the superiority and practicability of the theoretical system. Thus, the goal of sustainable development of bridges was achieved. The value of this re-search lies in establishing a comprehensive international project management system model; truly integrating sustainable development with project management; providing new research frames and management models to promote the sustainable development of the construction industry.

Since the outbreak of COVID-19, private kindergartens in China have encountered a crisis of survival and development. Whether private kindergartens can successfully overcome difficulties is related to the development goal of preschool education and more children’s enrollment needs could be met in the future. In order to realize the sustainable development of private kindergartens, literature review and interview are adopted in this paper to analyze the practical difficulties faced by private kindergartens during the epidemic. The following suggestions are proposed from the perspective of kindergarten internal management: kindergarten principals should assume the responsibility of management, adopt a variety of ways to reduce the turnover rate of kindergarten teachers, and establish the crisis management system in response to outbreaks.
