The Qinghai–Tibetan Plateau (QTP) has the largest area of natural grassland in China, and continuous degradation poses a serious threat to regional ecological security sustainable resource management. It is essential comprehensively evaluate cost–benefit differences drivers across various zones enhance management practices. This study presents zonal framework for restoration degraded grasslands based on analysis, specifically applied Qinghai Northeastern QTP. results indicate: (1) Although overall NDVI shows an upward trend, some areas still exhibit significant degradation. (2) Cost–benefit analysis can divide into four types Ecological Management Zones (EMZs): high-cost–high-benefit zone, high-cost–low-benefit low-cost–low-benefit low-cost–high-benefit zone. (3) driving factors show different EMZs. Based these research findings, differentiated spatial planning strategies were developed each EMZ. not only provides scientific methodology but also offers important insights resources QTP other ecologically sensitive areas.

Net primary productivity (NPP), a key indicator of terrestrial ecosystem quality and function, represents the amount organic matter produced by vegetation per unit area time. This study utilizes MOD17A3 NPP dataset (2001–2022) to analyze spatio-temporal dynamics in Xinjiang projects future trends using Theil-Sen trend analysis, Mann–-Kendall test, Hurst Index. By integrating meteorological data, this employs partial correlation Miami model, residual analysis explore driving mechanisms behind changes influenced climatic factors human activities. The results indicate that: (1) average has increased over years, displaying spatial pattern with higher values north west. Regions increasing outnumber those declining trends, while 75.18% shows un-certain trends. (2) Precipitation exhibits stronger positive compared temperature. (3) Climate change accounts for 28.34% variation NPP, activities account 71.66%, making latter dominant factor. aids monitoring ecological degradation risks arid regions China provides scientific basis developing rational coping strategies restoration initiatives.

ABSTRACT Grasslands, as a vital component of arid and semi‐arid terrestrial ecosystems, play pivotal role in carbon cycling ecosystem functioning. Climate change human activities significantly affected grassland productivity. Understanding the main driving factors their contribution rates is great significance for protection sustainable development grasslands. However, we still lack comprehensive understanding changes productivity Xinjiang. This study investigated spatiotemporal characteristics underlying actual net primary (AcNPP) Xinjiang from 2000 to 2022, utilising Carnegie‐Ames‐Stanford Approach geospatial detectors. Employing nonlinear Random Forest technique, assessed dual impacts climate on Our findings revealed that exhibited fluctuating growth during this period, with an average annual AcNPP rate 0.33 g C m −2 year −1 . Comprehensive evaluation soil type, precipitation, moisture content were key determinants spatial distribution AcNPP, higher values mountainous regions lower basins. The further change, activities, combined effects contributed recovery 60.97% grasslands drivers degradation, reaching 67.71%. Further analysis indicated water conditions, particularly precipitation content, forces Although grazing management strategies, such rotational stocking deferred stocking, facilitated 36.71% areas impacted by remains significant anthropogenic factor contributing degradation. These provide valuable scientific insights effective conservation Xinjiang's ecosystems.

This study explores conflict transformation practices and actors through an analytical research approach. It reveals that various engaged in peace initiatives have primarily focused on activities cantered around management, prevention, resolution. limited emphasis is attributed to a lack of governmental attention strategic planning this regard. Sources identified include grievances, animal raiding, land disputes, fishing rights, competition over water pasture resources. Efforts aimed at encompass resilience-building, rangeland NGO interventions dialogues, integration pastoralism agro-pastoralism with commercial agriculture, implementation drought early warning systems, resource management development, range rehabilitation, provision education affected communities. While these played significant role addressing conflicts transforming relationships, they are deemed insufficient inadequately executed for comprehensive transformation. Nonetheless, serve as vital drivers peace. Although the current mechanisms place not resulted changes situation, beginnings promising commendable.
