“…Pairwise comparisons in the observed years (1990, 2000, 2006, 2012, and 2018) were analyzed using the Wilcoxon signed-rank nonparametric test (for non-categorical and not normally distributed data). Similarly, the forest and water body area changes were analyzed using the Wilcoxon signed-rank test for the years 1990-2006, 2006-2018, and 1990-2018. Gain, losses, the rate of forest area, and water body change [33,96] were calculated using the following Formula (1):…”

Land cover evolution is an environmental factor that can be used to characterize forest ecosystem services (FES). This study aims to analyze the change in forest cover and water bodies between 1990 and 2018 in the whole Czech Republic, and in the Central Bohemian and South Moravian regions, and its effects on freshwater provision. Additionally, we attempt to understand the societal implications of water quality, public perception, and environmental investment on natural ecosystems. Forest cover and water body data were obtained from the Corine land cover database, while water quality and investment were compiled from the Czech Statistical Office. Public perceptions on the Czech FES were collected from a national survey. Between 1990 and 2018, forest cover has increased by 3.94% and water bodies by 7.65%; however, from 2014 to 2018, severe droughts were reported that compromised the availability of surface water, presumably on artificial structures, causing an increase in the occupied area. Regarding public perception, respondents with less education, and the older population, obtained an assessment of the low performance of the FES, while the water quality and investment indicate that environmental funding has contributed to improving the quality of outflow water from the wastewater treatment plants, fulfilling all the allowed limits of the urban wastewater treatment directive. Hence, a multidisciplinary approach can help decision makers promote policies that integrate environmental management measures, investment protection, and contribute to sustainable development.

“…The province was able to achieve an annual index average of 97 points from 2012 to 2014, but the annual index average dropped to 79 points from 2015 to 2017 [15]. Aerial views of vegetation cover variations in Tanah Papua over the last 17 years [18,19] confirm what the Land Cover Quality Sub-index shows. The status of forest cover in 2001 was substantially different from the level of tree cover in 2017.…”

Since the development of public and social infrastructure, such as road infrastructure, affects people's welfare, regional discrepancies in development are a key problem for Papua's infrastructure development. True, it's a top priority. When planning, executing, and overseeing road building, as it should be with the Trans-Papua route, public awareness and participation in the physical implementation of infrastructure development should be considered. The construction of the Trans-Papua Road drew a negative reaction and a huge amount of criticism from many social circles. A lack of community engagement in the development and implementation of the Trans-Papua Road project, as well as a public perception of ignorance, are accused of causing resistance and conflict. This research is an effort to understand better the awareness of specific communities, which may be used to design a participatory development strategy. The study's focus is on how the public views the Trans-Papua road's development from sociocultural, economic, and environmental viewpoints. The data was gathered through a survey and complemented with statistics from the local Central Statistics Bureau. The results showed that the community and stakeholders have different perspectives and understandings of the Trans-Papua road's construction, and it has been determined that the community should be involved in the planning and implementation of development measures based on the response of the local. This study demonstrates the importance of reducing community-government conflicts, especially those involving protected forest conservation, community empowerment, and transportation network development. The findings of this study can be used to provide recommendations for infrastructure development, particularly in locations where native communities are at threat of conflict.

According to the land cover classes of Indonesia [18], the forested area consists of primary and secondary dry land forest, primary and secondary mangrove, primary and secondary swamp forest. Further, cropland's classes are contained of estate cropland, pure and mixed dry agriculture, paddy field.…”

“…Even though different studies have been concerned with LUCC observation in Indonesia, the implementation of the remote sensing imagery in Papua Province is rarely done. Therefore, in the previous study, we were done to produce land use land cover maps in this Regency and the impact on the Sago palm was produced [18]. Hence, in present work we used Landsat imagery and supervised classification to evaluate the changes in land use types in the easternmost city in Indonesia.…”

Land use/cover change (LUCC) observation and determination have been extensively discussed in natural resources management, biodiversity and ecosystem preservation, land management also climate changes studies. An evaluation of the LUCC in Merauke, the easternmost city of Indonesia, was conducted to gain relevant information in agriculture and forestry based on historical data from remotely sensed land cover data. To obtain the historical dynamics of the LUCC, a supervised classification algorithm was implemented to the Landsat images of 1990, 1996, 2009, 2015, and 2019 as well as statistical analysis Wilcoxon signed-rank. This study aims to investigate and analyze the LUCC over a period of 29 years. The results show a significant decline in the forest area by around 7% in 2019. As compared to the LUCC in 1990, agriculture sectors such as dry-land agriculture, shrub-mixed dry land and paddy field gained an area higher than 50%, while the area of the water body is a declined by 0.61 % over the period. The evaluation of LUCC will help government development plans in the protection of commodities in this Province and the promotion for biomass and bioenergy resources.
