“…Agriculture disturbs the plant's metabolism by increasing chlorophyll content and respiration, decreasing photosynthesis, and damaging the leaves. Ramya et al [84] studied the impact of elevated ozone stress in rice cultivars, which causes leaf bronzing. Kim et al [68] fabricated the polymer tattoo sensor to monitor the ozone stress by monitoring the sensors' impedance changes.…”

Crop production is impacted by increased plant diseases and shifting environmental circumstances. Monitoring plant health is necessary to raise crop quality and productivity to meet population growth demands. Nanotechnology‐based sensor platforms provide real‐time plant monitoring capabilities, going beyond the constraints of conventional sensor technologies. Wearables are an evolving area of health monitoring and have been modified for agricultural purposes. Wearable sensors are placed on various plant organs in the agricultural industry to check the crops’ health continuously. The varieties of wearable sensor materials and their fabrications, followed by their sensing mechanisms, are highlighted in this review. Furthermore, monitoring plant micro‐environmental factors, including salinity, hazardous gases, and pesticides, are discussed. This text covers various internal plant growth factors monitoring, such as sap flow, transpiration, and signal monitoring. The challenges of wearable sensors in agriculture are mentioned toward the end.

“…Although, ground-level ozone is essential in the Earth's upper atmosphere, its presence in the lower atmosphere acts as a secondary air pollutant which negatively impacts human health and crops (Wilkinson et al, 2012). The effect of phytotoxic ozone concentrations on crop yields has been extensively studied (Pleijel, 2011;Arshad, 2021;Ramya et al, 2021;Wang et al, 2021;Shang et al, 2022).…”

The Mekong Delta region (MDR), also known as Vietnam's rice bowl, produced a bountiful harvest of about 23.8 million tons in 2020, accounting for 55.7% of the country's total production, providing food security for 20% of the world population. With the rapid pace of industrialisation and urbanisation, concentration of ozone in the lower atmosphere has risen to a level that reduces crop yields, especially rice, and is, therefore, the subject of research. This study has a goals to simulate the spatio-temporal distribution of ground-level ozone in the area, also to evaluate the impact of precursor emissions and meteorological factors on spatio-temporal distributions of concentration. The study area was divided into six agro-ecological zones to clarify the role of emissions in each zone. The simulation resultsshowed that the ground-level O 3 in the MDR ranged from 40.39 µg/m 3 to 52.13 µg/m 3 . In six agroecological zones, the average annual ground-level O 3 concentration was relatively high, and was the highest in areas six (CZ) and seven (CPZ), with 46.11 µg/m 3 and 46.41 µg/m 3 , respectively. In each zone, the annual average O 3 concentration tended to gradually increase from the inner delta to coastal areas.Two types of precursors, NO x and NMVOCs, are the main contributors to O 3 pollution, with the largest contribution coming from zone 1 (FAZ) with 91.5 thousand tons of NO x /year and 455.2 thousand tons of NMVOCs/year. Among the meteorological factors considered, relative humidity (RH) and surface pressure (P) were the two main factors that contributed to the increase in ground-level ozone. The spatio-temporal distribution of ground-level O 3 in the MDR was in uenced by emission precursors from different zones as well as meteorological factors. The present results can help policymakers formulate plans for agroindustrial development in the entire region.
