The Altai Mountains region, characterized by its unique biodiversity and significant ecological value, is increasingly under pressure from anthropogenic activities climate change. This study investigates the spatial temporal dynamics of forest grassland ecosystems in National Park Candidate Area 2000 to 2020, proposes a comprehensive framework for conservation management national parks. Through detailed analysis land cover changes, we observed expansion 13.65% degradation 11.69%. Rapid occurred before 2010, followed accelerated after that, with 2010 identified as critical turning point. Our highlights role key drivers, such soil type, elevation, cropland expansion, human activities, shaping these ecosystems. Using Geodetector propensity score matching methods, evaluated effectiveness existing protected areas mitigating loss. While effectively contributed restoration, they were less successful preventing decline, underscoring need integrated approaches. findings this provide insights into ecosystem effectiveness, offering valuable guidance establishment national-park-type broader regional efforts.

The Greater Mekong Subregion (GMS) economic cooperation program is an effective and fruitful regional initiative for socioeconomic development in Asia; however, the vegetation change trends directions GMS caused by rapid remain unknown. In particular, there a current lack of comparative studies on changes various countries GMS. Based MODIS normalized difference index (NDVI) time series data, this study analyzed spatiotemporal patterns coverage their from 2000 to 2022 using Theil–Sen slope estimation, Mann–Kendall mutation test, gravity center migration model. key findings were as follows: (1) NDVI showed overall upward fluctuating trend over past 23 years, with annual growth rate 0.11%. varied slightly between seasons, greatest increases recorded summer winter. (2) spatial distribution greatly, higher values north–central region lower south. (3) A total 66.03% area increments during studied period, mainly south–central Myanmar, northeastern Thailand, Vietnam, China. (4) From 2022, greenness shifted northward GMS, especially 2005, indicating that rates part than those Furthermore, all countries, except Cambodia, increased, most pronounced Overall, these can provide scientific evidence enhance ecological protection sustainable development.

Abstract Afforestation of abandoned cropland represents a promising strategy for land-based climate change mitigation, particularly in regions where land resources additional afforestation are limited. However, the carbon sequestration potential such remains largely unknown. Here, we assess spatial distribution China and its through incentives, using 10,818 empirical data derived from 298 peer-reviewed articles, multisource remote sensing data, machine learning models. We identify 6.03 Mha that have been undergoing natural regeneration since early 21st century. This has to sequester an 215.12–218.94 Tg biomass 15.87–17.64 soil organic (SOC) by 2060, representing 51.95–53.94% increase compared alone. Our results further show benefits could offset 47.71–49.57% government investments (approximately USD 16.254 billion) cropland. findings highlight significant on support China’s neutrality goals, while also offering cost-benefit framework guide policy decisions.

Abstract Grain for Green Program (GFGP), China's most famous ecological program, has become the main driver of carbon sink increases. However, potential effect still lacks scenario‐based systematic estimation. By backdating GFGP increase in Loess Plateau (LP) over past 20 years, we forecast and reveal spatial distribution contribution “Double Carbon Target” years under three scenarios. Our results showed that places restored to forests (GFGP‐Forest) will always lead a by (33.62 Tg C 2000–2020) 0.78–1.09 1.29–2.13 2030 2060, respectively. grasslands (GFGP‐Grassland) an 2000–2020 (72.52 C), but decrease 2060 (0.89–9.95 7.42–11.18 C). This conversion is due combination Net Primary Productivity heterotrophic respiration future, which indicates restoration programs involved converting croplands into severely benefits potential. In summary, it essential correctly quantify LP resulting from GFGP, properly manage augment GFGP‐Forest avoid source GFGP‐Grassland future. highlight hidden danger leaking typical semi‐arid region future climate‐changing conditions.

In the past, during development processes, major ecological and environmental problems have occurred in agro-pastoral ecotone of China, which had a strong impact on regional sustainable development. As such, analyzing evolution ecosystem service value (ESV) predicting futural spatio-temporal under different scenarios will provide scientific basis for further This research analyzed land use cover change (LUCC) from 2000 to 2020, adopted Mark-PLUS model construct (prioritizing grassland development, PDG; prioritizing cropland PCD; business as usual, BAU), simulated future LUCC. The driving factors influencing each type were revealed using PLUS model. Based LUCC data, distribution ESV was calculated via equivalent factor method, including four primary services (supply service, adjustment support cultural service) eleven secondary (water resource supply, maintaining nutrient circulation, raw material production, aesthetic landscape, food purification, soil conservation, biodiversity, gas regulation, climate hydrologic regulation). results showed that total increased first then declined reaching highest CNY 8207.99 million 2005. scenarios, shows trend PGD (CNY 8338.79 million) > BAU 8194.82 PCD 8131.10 million). global Moran index also follows this distribution. Additionally, precipitation (18%), NDVI (16%), DEM (16%) are most important spatial agglomeration characteristics Moran’s local indicators auto-correlation, show high coordination degree between high–high cluster areas water areas. These point out key points next step restoration projects help with achieving goals more effectively.
