Clean air is critical component for health and survival of human wildlife, as atmospheric pollution associated with a number significant diseases including cancer. However, due to rapid industrialization population growth, activities such transportation, household, agricultural, industrial processes contribute pollution. As result, has become problem in many cities, especially emerging countries like India. To maintain ambient quality, regular monitoring forecasting necessary. For that purpose, machine learning emerged promising technique predicting the Air Quality Index (AQI) compared conventional methods. Here we apply AQI city Visakhapatnam, Andhra Pradesh, India, focusing on 12 contaminants 10 meteorological parameters from July 2017 September 2022. this employed several models, LightGBM, Random Forest, Catboost, Adaboost, XGBoost. The results show Catboost model outperformed other models an R2 correlation coefficient 0.9998, mean absolute error (MAE) 0.60, square (MSE) 0.58, root (RMSE) 0.76. Adaboost had least effective prediction 0.9753. In summary, being best-performing prediction. Moreover, by leveraging historical data algorithms enables accurate predictions future urban quality levels global scale.

Interlinkages between Climate Change and Food Systems: The Impact on Child Malnutrition—Narrative Review

Nutrients, Journal Year: 2023, Volume and Issue: 15(2), P. 416 - 416

Published: Jan. 13, 2023

The pandemics of obesity, undernutrition, and climate change represent severe threats to child health. They co-occur; interact with each other produce sequelae at biological, psychological, or social levels; share common underlying drivers. In this paper, we review the key issues concerning diet nutritional status, focusing on interactions food systems. Inadequate infant young feeding practices, insecurity, poverty, limited access health services are leading causes malnutrition across generations. Food system industrialization globalization lead a double burden malnutrition, whereby undernutrition (i.e., stunting, wasting, deficiencies in micronutrients) coexists overweight as well harmful effects climate. Climate COVID-19 pandemic worsening impacting main household security, dietary diversity, nutrient quality, maternal health), social, economic, political factors determining security nutrition (livelihoods, income, infrastructure resources, context). Existing interventions have potential be further scaled-up concurrently address overnutrition, by cross-cutting education, agriculture, systems, safety nets. Several stakeholders must work co-operatively improve global sustainable nutrition.

Improving water use efficiency in vertical farming: Effects of growing systems, far-red radiation and planting density on lettuce cultivation

Agricultural Water Management, Journal Year: 2023, Volume and Issue: 285, P. 108365 - 108365

Published: May 23, 2023

Vertical farms (VFs) are innovative urban production facilities consisting of multi-level indoor systems equipped with artificial lighting in which all the environmental conditions controlled independently from external climate. VFs generally provided a closed loop fertigation system to optimize use water and nutrients. The objective this study, performed within an experimental VF at University Bologna, was quantify efficiency (WUE, ratio between plant fresh weight volume used) for lettuce (Lactuca sativa L.) growth cycle obtained two different growing systems: ebb-and-flow substrate culture high pressure aeroponic system. Considering total consumed (water used irrigation climate management), WUE aeroponics 28.1 52.9 g L−1 H2O, respectively. During cycle, contribution generated by recovery internal air moisture heating, ventilation conditioning (HVAC) system, quantified. Indeed, recovering dehumidifier, decreases dramatically (by 67 %), while increased 206 %. Further improvement through ameliorated crop management strategies, particular, increasing planting densities (e.g., 153, 270 733 plants m−2) optimizing light spectrum adjusting amount far-red radiation spectrum). Strategies efficient high-tech therefore proposed.
