The phenological characteristics of plants can reflect both their responses to environmental changes as well an ecosystem's sensitivity climate change. Although there have been several studies plant species worldwide, is minimal research on the phenology vegetation found in extremely arid environments within context To address this gap, study investigated effects climate-hydrological factors, including temperature, precipitation, surface and humidity, (start growing season [SOS] end [EOS]) Populus euphratica Tarim Desert Oasis. Using Landsat 7/8 satellite imagery field data, we analyzed spatial temporal variations SOS EOS from 2004 2023. availability water, particularly groundwater depth directly determined distribution P. impact increasing temperatures varied under different moisture conditions;: high-moisture environments, increased promoted earlier delayed EOS, with opposite conditions occurring low-moisture environments. highlights profound influence change, especially extreme regions. accurately predict response future ecological models should incorporate hydrological soil moisture, cold dry These findings provide important insights for developing effective protection management strategies.

The fires of the forest and peatland are serious environmental threats. In addition to damaging ecosystems, these also cause extensive health, social, economic impacts. middle mitigation efforts, social capital plays an important role in strengthening capacity local communities prevent deal with disasters. This study aims explore fire using a qualitative approach. case was implemented Tanjung Belit Village, Bengkalis, involving in-depth interviews stakeholders, such as Disaster Care Community (MPB), communities, government. results indicate that form trust, shared norms, networks key elements driving collective action increasing effectiveness programs. active involvement understanding wisdom, synergy between actors main drivers prevention efforts success fire. concludes is strategy must be prioritized community-based disaster policies achieve sustainability.
