Microplastics (MP) pollution in agricultural soils has become an important environmental problem. Phosphorus (P) is a key nutrient for plant growth. P fertilizers are mainly applied to agricultural fields to achieve the high production expected by farmers. The experiment included two MP levels (0, 1 % w/w) and two P levels (0 mg kg(-1) , 200 mg kg(-1) ) in order to know whether MP effects on wheat and maize are regulated by supplemental P supply. MP decreased plant height, photosynthetic pigment, and chlorophyll fluorescence parameters, while increased ROS and MDA contents. Wheat and maize exhibited distinct strategies in mitigating growth damage caused by MP pollution: wheat primarily increased the AsA contents, while maize predominantly enhanced APX activity. P supply alleviated the MP pollution effect by improving photosynthetic pigments, POD, and PPO activity in wheat and maize. P supply alleviated the MP pollution effect by improving antioxidant enzyme activities in the AsA-GSH cycling in wheat, while increasing non-enzymatic antioxidant contents in the AsA-GSH cycling in maize. The results showed that wheat and maize resisted MP pollution by different mechanisms, and P supply reduced the sensitivity of wheat and maize to MP pollution and its regulatory effect on wheat was better than that on maize. Synopsis: The response of different plants under the same microplastic and phosphorus conditions is limited. We find phosphorus alleviates microplastics pollution on wheat and maize through different regulatory routes.
Hydrometeorological extremes, such as droughts, are a major threat to society and can have extensive damaging effects. In this study, daily rainfall estimates from the Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) quasi-global rainfall dataset were used to calculate the Standardised Precipitation Index (SPI) for the assessment of meteorological drought in Southern Province, Zambia. Normalised Difference Vegetation Index (NDVI) imagery (250 m resolution) from MODIS-Terra, for the period 2000-2021, were used to derive the Standardised Vegetation Index (SVI) in order to assess agricultural drought. The Mann-Kendall trend test and Sen's slope were used to determine the spatial-temporal trends and their magnitudes. This study demonstrated that the droughts of the Southern Province of Zambia can be classified into two categories: regressive and aggressive droughts. Regressive droughts are associated with moderate to strong El Nino events. Although El Ni & ntilde;o events undermine water security, regressive droughts tend to result in resilient vegetation owing to residue soil moisture. In contrast, aggressive droughts are characterised by an increase in drought intensity as the season progresses. Water security prospects in the region should focus on climate-smart approaches, such as managed aquifer recharge, to ensure water availability even under extreme drought conditions.

The effect of seismicity in earthquake-prone areas is soil liquefaction. This common geohazard that usually occurs in the world induces fatality damage to buildings and infrastructure. Consequently, preventive effort is required to avoid this condition's harmful effects. Two countries that have outstanding seismic records and soil liquefaction damage histories are Japan and Indonesia. However, liquefaction research in Indonesia is not fully developed yet to assess the liquefaction vulnerability as the mitigation countermeasure as Japan did. This paper aims to generate potential proposals in soil liquefaction research between Indonesia and Japan that will be able to expand in terms of disaster prevention. A bibliometric analysis with Vosviewer was conducted to provide a lot of potential topics in soil liquefaction. Moreover, the research data from the Scopus database was analyzed to list the similarities and differences topics between the two countries. Moreover, comprehensive methods such as empirical, semi-empirical, and computational analysis have been widely mentioned and discussed between the results of the two countries. The results indicate that Indonesia's liquefaction susceptibility analysis should consider Japan's research categories. The research's main contributions are highlighting the many applications of soil vulnerability research in Indonesia and Japan, indicating possible areas of research that have not been explored, and summarizing the exciting possibilities for future research in this subject.
