SIDR had great impact on crop, livestock and fisheries at Pirojpur district in Barisal Division. To perform this study data were collected from the three selected village (south Shailkati, Hothkhali and Lahori) affected people by random sampling after selecting the study topic and area. SIDR also created a great impact on the production of different types of crop. Rice production was reduced to 7.5%, chili to 11.66% and vegetables to 10%. After SIDR the production of pulse was increased 21.67% due to increase in acreage in Pirojpur. From this study we found vegetables lands (58.33%) and fish in river (70.83%) were affected by the saline water than the rice (33.33%), fruit (9.16%) and fish in pond (24.16%) respectively. Due to the tidal surge and storm the cattle reduced to 18%, goats to 14%, buffalos to 21%, chickens to 10.09%, duck to 8.82%, Pigeons to 24%; that means majority of the poultry birds were reduced than the livestock. The food habit of the affected people was also changed. They now took more flour rather than rice. The scarcity of agricultural production created the reduction of food stock. Most of the respondents had no food stock. But the situation is better than close post SIDR period. Most of the cases they are adopting with the changing socio-economic conditions.

An experiment was conducted at the Field Laboratory of Department of Environmental Science, Bangladesh Agricultural University, Mymensingh, Bangladesh to evaluate the radiation use efficiency (RUE) in different row orientation of maize, to determine parameters affecting RUE and to make a comparison of results of the study with previous results observed at different location of the world. The dry weight was taken at 7 days interval by destruction of five plants and kept them oven drier at 80 o C for 48 hours and it was expressed as gm 2 . Dry matter accumulation values at different dates of sampling were regressed with the corresponding cumulative intercepted PAR values and the slope of the regression line was then taken as RUE. The efficiency of radiation utilization varies throughout the crop life cycle. Radiation use efficiency (RUE) was positively correlated to leaf area index (LAI), leaf chlorophyll content, extinction coefficient (k), incident radiation and total solar period of crops and negatively correlated to water stress and light reflection. RUE was highest in vegetative stage, where RUE was higher (0.89 gMJ -1 PAR) in N-S row orientation than E-W row orientation (0.75 gMJ -1 PAR), after that RUE decreased gradually in tasseling stage. Again RUE was slightly increased during maturity. RUE of maize was almost similar with the findings of other researchers and it ranged from 0.85 to 1.5 gMJ -1 , it was due to similar plant architecture and stand duration.

Abstract:A survey was conducted to get an overview and to gather information on the existing and socioeconomic condition of the SIDR affected people and migration. To perform this study data were collected from the three selected village (south Shailkati, Hothkhali and Lahori) affected people by random sampling after selecting the study topic and area. Then the data were processed and analyzed through using different statistical tools like pie-chart, bar diagram, table etc. The GoB and NGO's subsidiaries, also help the SIDR victims to cope with the situation. From the study we found that the NGO's contributed more to adapt with the situation. After SIDR the occupation of non-agriculture day-labour increased (37%) and the occupation of agriculture decreased 31% from 55.64%. After SIDR middle income group people were greatly affected. The income and expenditure of middle income group people were found to reduce. Low income group people increased their income and expenditure was decreased. After SIDR due to decrease their average income, they could not manage their basic needs. The food habit of the affected people was also changed. They took more flour rather than rice. The scarcity of agricultural production created the reduction of food stock. Most of the respondents had no food stock. The rate of internal migration was also increased. The rate of migration to other places (47%) and Dhaka (53%) was increased due to SIDR. But the situation was better than close post SIDR period. Most of the cases they are adopting with the changing socio-economic conditions.
