Effect of air pollution on peri-urban agriculture: a case study
Peri-urban agriculture is vital for the urban populations of many developing countries. Increases in both industrialization and urbanization, and associated air pollution threaten urban food production and its quality. Six hour mean concentrations were monitored for SO 2, NO 2 and O 3 and plant resp...

Summary: | Peri-urban agriculture is vital for the urban populations of many developing countries. Increases in both industrialization and urbanization, and associated air pollution threaten urban food production and its quality. Six hour mean concentrations were monitored for SO
2, NO
2 and O
3 and plant responses were measured in terms of physiological characteristics, pigment, biomass and yield. Parameter reductions in mung bean (
Vigna radiata), palak (
Beta vulgaris), wheat (
Triticum aestivum) and mustard (
Brassica compestris) grown within the urban fringes of Varanasi, India correlated directly with the gaseous pollutants levels. The magnitude of response involved all three gaseous pollutants at peri-urban sites; O
3 had more influence at a rural site. The study concluded that air pollution in Varanasi could negatively influence crop yield.
Urban air pollution has a negative impact on peri-urban agriculture. |
