Abstract

Biodiversity in Bangladesh is deteriorating gradually due to many anthropogenic activities. Agricultural practices along with modern farming techniques causing depletion of biodiversity. The study was conducted to determine the impacts of agricultural practices on biodiversity in the study area. Cultivable land increase only 1% but total cultivable land came under irrigation. Cropping in wetland area got popular and increase 95% in term of land area. As water level goes down, digging pond in wetland area became a trend recently. Simultaneously, the use of submersible water pumps gaining popularity. Agricultural practices shift dramatically from inorganic fertilizer to organic fertilizer and chemical fertilizer. The numbers of pesticides use reached three folds. On the other hand, floral and faunal species is losing its diversity in the study area. Total, 29% fruit plants, 38% timber plant and 42% medicinal plant species extinct. In case of fauna, 33% wild animal, 26% birds and 46% fish species extinct form the study area. People perception mentioned cultivation land used pattern, use of chemical fertilizer, pesticide etc. irrigation, cultivating hybrid, HYV and exotic plant, use of modern agriculture technology, habitat destruction, infrastructural development, urbanization etc. as the causes of loss of biodiversity. But, in this study finds most of the biodiversity caused by anthropogenic activities. Farmers of the study area have no training of any kinds of fertilizer using but they admit that conserving biodiversity is important. Anthropogenic agricultural effects on biodiversity are a field needs further research, particularly about the conditions where native and diverse species may sustain and flourish.
