| dc.description.abstract | A study was conducted to investigate the impact of brickfield on carbon dioxide
emission and livelihood of brickfield workers in Chilmari and Ulipur upazila under
Kurigram district. The study was conducted during the period from January to July 2017.
It was a survey based study where data were taking from twenty (20) brick fields on the
study area. Data has been collected based on questionnaires form. Data about production
of bricks, fuel consumption rate and livelihood of brickfield workers, information about
various crops production adjacent about one km, two km and five km were collected
physically from some selected brick kilns and the adjacent area of brickfields.
Measurement of the variables constitutes is an important task of any social research. In
this study, carbondioxide emission from brickfields, brickfield workers livelihood and
various crops production adjacent to brickfields were the focus issues. In addition
owners, workers and farmer's age, education, family size, sex, farm size, kiln height,
labor, power supply, fuel use, production of bricks, CO2 emission, production of crops,
physical effect, environmental effect, income level of brickfield workers, workers
satisfaction, family types of farmers, farm size of farmers, farmers innovativeness,
occupation of farmers, annual income of farmers and agricultural knowledge were
selected characteristics of this study. The mean of the brickfield kiln height was 30.05 m.
There was 85% owner used generator and 15% owners used electricity to control the
exhaust fan. In Kurigram districts 90% brick field owners were used coal and only 10%
owners were used wood as brick field fuels. The uses of natural gas in brick fields was
absent in Kurigram district. The mean of the brick production was 2.28 million among
20 brickfields. The maximum amount of CO2 emission was 7.94 (t/lakh bricks) and
minimum amount was 3.64 (t/lakh bricks). Maximum workers were affected in back
pain (33.3%) whereas minimum affected by cough (3.3%) due to brick field emissions.
Maximum brick field workers (62.2%) commented that flying ashes was more emitted
from the brick field. Again, 24.4% workers commented that emitting ashes from brick
kiln were usually burn tree and crops. Moreover, 7.5% stated that the kiln was caused
heat. 95% farmer used tractor for the land preparation, 71% farmer cultivated hybrid
variety of rice, 26% farmer used BADC seed for crop cultivation, 13% farmer used sex
pheromone and 4% used bio fertilizer and 2% used IPM in rice field. The study also
revealed that the yield of the principle crops like wheat, potato, jute, aus, aman and boro
rice were higher with the increased distance from the brickfield. However, due to the
high demand of infrastructure development brick making industries in Bangladesh is a
rapidly growing sector. Therefore, to minimize the negative impact of brick fields on
agricultural land and nearby environment, appropriate knowledge about agricultural
production technology, installation of modern brick kilns, proper awareness among local
farmers, brick field owners and brickfield workers are needed. | en_US |
