Greening dryland ecosystems greatly benefits from significant CO2 fertilization. This greening trend across global drylands, however, has also been severely constrained by enhancing atmospheric and soil water (SW) deficits. Thus far, the relative offsets in contributions between vapor pressure deficit (VPD), SW at varying depths, fertilization to vegetation dynamics, as well differences impacts of decreasing different depths on over long periods, remain poorly recorded. Here, this study comprehensively explored dynamics high VPD, low SW, rising concentration drylands during 1982–2018 using process-based models satellite-observed Leaf Area Index (LAI), Gross Primary Productivity (GPP), solar-induced chlorophyll fluorescence (SIF). Results revealed that decreasing-SW-induced reductions LAI were larger than those caused VPD. Furthermore, was more subsurface (7–28 cm) among various layers. Notable found enhanced constraints fertilization, with former offsetting approximately 38.49% beneficial effects latter changes drylands. Process-based supported finding increasing failed overwhelmingly offset ecosystems. work emphasizes impact highlights far-reaching importance despite constraints.

Urbanization in large cities has altered the urban thermal balance, creating heat islands. In this context, green areas are crucial regulating climate. This study uses remote sensing data to evaluate their performance using fractional vegetation cover (FVC) and its impact on land surface temperature (LST) Metropolitan Lima, Peru, between 1986 2024. The spatial temporal relationship FVC LST is analyzed, districts classified based effectiveness regulation. Mann–Kendall test was applied identify trends along with a Spearman correlation analysis clustering group according cooling of areas. results show that expansion increased by an average 6.43 °C since 1990, there significant negative (p < 0.001) LST, indicating positive impacts at level. However, it does not reduce suggests that, while effective locally, insufficient counteract overall warming over time. Based characteristics, have been into four groups: those well-preserved areas, such as La Molina San Isidro, which lower compared where urbanization replaced vegetation, Carabayllo Lurigancho (Chosica). Finally, highlights importance integrating area management planning mitigate promote sustainable development.

Wetland vegetation is vital for ecological purification and climate mitigation. This study analyzes the spatiotemporal characteristics influencing factors of water areas, fractional cover (FVC), land use types in Poyang Lake wetland across wet dry seasons (1990–2022) using remote sensing technology. The results showed that area remained overall stable during but decreased significantly (19.27 km2/a). FVC exhibited an increasing trend, with expanding from lake margins to central areas. areas shallow water, bare ground, Phalaris arundinacea–Polygonum hydropiper (P. arundinacea–P. hydropiper) communities interannual fluctuating decreases, while other increased. From 1990 2020, changes were mainly characterized by transformation into deep Carex cinerascens (C. cinerascens) community ground as well P. C. community. Rising temperatures enhanced both seasons, stimulated expansion total area, reduced season area. Decreasing accumulated precipitation exacerbated loss decline communities. These findings provide critical insights conservation sustainable management.
