The increasing use of traditional agricultural plastic mulch films (PMs) has raised significant environmental concerns, prompting the search for sustainable alternatives. Soil-biodegradable (BDMs) are often proposed as eco-friendly replacements; however, their widespread adoption remains contentious. This review employs a comparative life cycle assessment perspective to evaluate impact PMs and BDMs across production, use, end-of-life stages, providing strategies mitigate on agroecosystems. generally exhibit lower energy greenhouse gas emissions than but contribute greater land-use demands. Reported eutrophication acidification potentials less consistent, varying based feedstock types scope BDM, well management PM. burden both is influenced by stage, polymer composition, farming practices, additives, film thickness, local climatic conditions. manufacturing stage major contributor BDMs, despite shared benefits crop yields. However, post-use impacts more pronounced PMs, driven strategy adsorbed waste content. While starch-based offer alternative uncertainties regarding residence time BDM residues in soil (albeit shorter PM residues) effects health, coupled with higher production costs, impede adoption. For end-of-life, biodegradation recommended.

A comprehensive investigation into the aero-thermodynamic impacts of UAV-generated airflow on rice microclimate is essential to elucidate complex relationships between wind speed, temperature, and temporal dynamics during critical growth stages rice. Focusing vulnerable such as heading, panicle, flowering, this research aims advance understanding microclimatic influences crops, thereby informing development UAV-based strategies enhance crop resilience optimize yields. By utilizing UAV rotor downwash, examines temperature speed at three key diurnal intervals: 9:00 a.m., 12:00 p.m., 3:00 p.m. At UAV-induced creates a stable with favourable temperatures (27.45–28.45 °C) optimal speeds (0.0700–2.050 m/s), which promote support pollen transfer grain setting. peak 2.370 m/s, inducing evaporative cooling while maintaining stability, yet leading some moisture loss. reach 28.48 °C, 72% decrease in from midday, effectively conserving phases. The results reveal that positively panicle flowering stages, where carefully moderated (up 3 m/s) reduce sterility, fertilization, reproductive development. This highlights potential UAV-engineered management mitigate stress factors improve yield through targeted regulation. Key agronomic parameters showed significant improvements, including stem diameter, canopy regulation, filling duration, productive tillers (increasing by 30.77%), total tillers, flag leaf area, grains per (rising 46.55%), biological yield, (surging 70.75%), harvest index. Conclusively, effects were observed a.m. applications outperforming midday late-afternoon treatments. Additionally, significantly increased yield. interaction timing stage (RRS × GS) exhibited low moderate effects, underscoring importance precise maximizing productivity.

However, by noon, increased variability caused slight drop to 29.11°C 0.26749), raising risk heat stress. Afternoon temperatures remained steady at 29.18°C but exhibited highest 0.27663), signalling potential disruptions could reduce grain yield. ‘Wind‐speeds followed clear pattern, rising 33.33% from (1.2 m s −1 ) noon (1.6 dropping 37.5% afternoon’. ‘This emphasizes importance precise operation timing, aligning rotor schedules natural achieve an 18.2% increase crop yield 25.8% reduction thermal stress’.
