| dc.description.abstract | Urbanization is a contemporary global trend resulting from population growth and migration, which concentrates the demand for food, energy and land at place of aggregation exerting pressure on the natural resources, leading to major changes in ecosystem and its services. Present study was aim to assessing the consequential changes in the plant diversity in agroecosystem along the rural urban transition (RUT) of Bengaluru. A total of 208 plant species were recorded in the agroecosystems along the RUT zones of Bengaluru out of 208 species 62 were cultivated crop species. Highest numbers of vegetable, fruit and flower crop species were found in the urban and transition zones, while in the rural zone number of staple food crop species cultivated were more. Similar trends were noticed in case of area cultivated across RUT zones. The chemical fertilizers and pesticides required for cultivation of vegetables, fruits and flower crops is found to be more compared to staple food crops. The source of water contamination is leaching and runoff of fertilizers and pesticides from agriculture fields, since higher quantities of these chemicals used in the cultivation in urban and transition zones is bound to add more contaminants to water bodies. From water quality it is found that in urban and transition zones water bodies are more contaminated compared to rural zone. Similar trend of soil quality deterioration was also noticed in RUT zones. Present study indicates the influence of urbanization on the biodiversity of agroecosystems of Bengaluru. | en_US |
