Summary: This study aims to characterize forest cover transitions and identify degraded or at-risk areas in North Korea. Using phenological information and random forest classifiers, a deforestation classification was performed. The analysis of deforestation dynamics from 1990 to 2020 revealed severe degradation and fragmentation of forests in North Korea.

Summary: South and North Korea have experienced contrasting economic developments since the 1950s despite sharing similar climates. The greening rate in North Korea over 1986-2017 was almost twice that of South Korea, with the expansion of agricultural facilities in South Korea's cropland being the main cause of the greening discrepancy. CO2 fertilization effects and transitions from grassland to cropland promoted an increase in NDVImax in North Korea, while deforestation led to decreasing NDVImax in forest areas.

Summary: Changes in tree cover can affect surface temperatures due to asymmetric direct biophysical effects. The cooling effect of tree cover gain is greater in magnitude than the warming effect of tree cover loss in most forests. Neglecting this asymmetric temperature effect of fine-scale tree cover change ignores the fact that biophysical feedbacks continue to cause surface temperature changes even under net-zero tree cover changes. Thus, it is necessary to account for gross, rather than net, tree cover changes when quantifying the biophysical effects of forests.

Summary: Deforestation has negative impacts on the ecological integrity of rivers and streams, causing threats to biodiversity and ecosystem services worldwide. This study examines the effects of forest cover changes on tropical streams using stable isotopic ratios. The results show significant variations in isotopic ratios and highlight the importance of using stable isotopes to monitor and assess the impacts of deforestation on stream ecosystems.

Summary: In response to deforestation, North Korea has implemented a national policy for forest restoration over the past decade. Satellite-based monitoring was used to evaluate the degradation and restoration of forests, with a focus on vegetation dynamics and surface temperature changes. The results showed significant increases in vegetation greenness due to forest restoration, particularly in Pyongyang and Pyongannam-do. The analysis also revealed a correlation between improved vegetation and decreased surface temperature. This study highlights the importance and positive effects of forest restoration on ecosystem services.

Summary: Recent studies in Haiti using high resolution imagery showed a net increase in tree cover equivalent to 5.0% of the land area between 2002 and 2010. Gross gains and losses accounted for 9.0% and 4.0% of the territory, respectively. This challenges previous narratives about ongoing forest or tree cover loss in Haiti.

Summary: This study uses satellite data to demonstrate the contrasting effect of forests on summer cloud cover in different regions, with temperate and boreal forests enhancing clouds and forests in the Amazon, Central Africa, and Southeast US inhibiting clouds. The spatial variation in cloud effects is driven by differences in sensible heat.

Summary: This research demonstrates how the combination of high-resolution LiDAR data and historical aerial photos can overcome challenges in assessing long-term tree canopy cover changes. The methods outlined in this study are suitable for detecting small-scale canopy changes over long time frames when inconsistent data types are available between the two time periods.

Summary: This study investigates the impact of drought on HCHO concentration in South Korea and finds that drought leads to an increase in HCHO, which is correlated with the vegetation percentage of the region.

Summary: The agricultural frontier expansion in the Cerrado biome has made Brazil a leader in commodity exports, leading to landscape changes. Accurate land use and land cover monitoring in this region is crucial for Brazil's security policies. The China-Brazil Earth Resources Satellite Program provides useful data for independent territorial management in Brazil, and data cubes created from CBERS-4/WFI have proven to be effective in improving crop monitoring using machine learning techniques in the Cerrado biome.

Summary: A study in South Korea examines the association between different types of vegetative cover and perceived stress. The results show that forest cover is consistently negatively associated with perceived stress at a nationwide scale, while grass cover and NDVI have mixed associations. The study suggests that local governments need to develop specific urban greening strategies based on sociodemographic and environmental conditions for health promotion.

Summary: Drought has a significant impact on the economy of a region, and its severity is determined by the level of infrastructure in the affected area. This study compared drought indices in North Korea and South Korea to understand the differences in agricultural infrastructure and their impact on drought. The findings suggest that different agricultural systems result in different drought impacts.
