Abstract
Water is most valuable resource available to man for his domestic, agriculture and
industrial uses. Time extends water being polluted by means of disposal of wastes,
effluents of the factories from urban centers, sewage etc. Ever increasing population,
massive urbanization and indiscriminate use of chemicals in agriculture accelerated water
pollution and gradual deterioration of its quality. Hence a research study was conducted
to know the "Impact of urban waste water pollution of Bellandur and Vrishabavathi river
valley on agriculture in the peri urban Bangalore". Bangalore East and Ramanagara
taluks were purposively selected for the study. The data was collected through interview
schedule. The results of the study revealed that majority of the farmers belonged to old
age group, medium level education, medium level farming experience, possessed
medium level land holdings, practices agriculture as a main occupation, medium level
annual income. Majority 100 percent of the farmers use polluted water for irrigation.
Majority of the farmers had high awareness about the use of waste water 38 and 40
percent respectively in both the sample areas. Major crops grown using waste water are
paddy, ragi, maize, coconut, banana, vegetable crops, mulberry, fodder grasses etc. The
study also reveled that education, annual income, occupation, mass media participation,
risk orientation, economic orientation, attitude towards waste water use were found to
have significant relationship with their awareness on dimensions like deterioration of soil
health and ecosystem, animal health, human health, ground water quality and quality of
agricultural produce. Urban domestic effluents, urban sewage, urban solid wastes and
untreated effluents from industries are the main sources of pollution. Major constraints
faced by the farmers in the sample area are lack of technical expertise to mitigate the
waste water pollution, deterioration of agricultural produce, lack of water management
practices, effect on human health and effect on soil health.
