Urban botanical garden plays an important role in mitigating hazards evolved due to climate change through sequestering atmospheric carbon dioxide. The study was conducted during the period of January to April 2018 to the estimation of ecosystem carbon stock and tree species diversity at National Botanical Garden, Dhaka, Bangladesh. Using transects line method square plots with a size of 20 m × 20 m were taken. So altogether there were total eighty three sample plot in National Botanical Garden. Above ground carbon (AGC) and below ground carbon (BGC) biomass stock was 192.67 and 31.34, respectively and soil organic carbon mean value of 27.52 Mg ha -1 , 21.45 Mg ha -1 and 16.23 Mg ha , respectively for 0-10 cm depth, 10-20 cm and 20-30 cm depth. The average number of trees in National Botanical Garden (233 tree ha -1 ), basal area (21.45 m ha -1 ) and mean DBH (39.86 cm). Tree diversity range from 0.25 to 1.86 and the mean value of (0.93 ± 0.14) in National Botanical Garden. Relationship such as biomass carbon with basal area, mean DBH, stem density and tree diversity were estimated. Among these the relationship between basal area and biomass carbon showed positive significant correlation. Therefore, the results of the study confirmed that the selected botanical garden can serve as a valuable ecological tool in terms of carbon sequestration, diverse tree species and storage of soil organic carbon. -1 2
IMPACT OF BRAC MICRO-CREDIT PROGRAM ON SOCIO-ECONOMIC UPLIFI'MENT OF RURAL WOMEN BENEFICIARIES
(DEPT. OF AGRICULTURAL EXTENSION & INFORMATION SYSTEM, 2007) HOSSAIN, MD. DELWAR
micro credit program measured by computing change in income, change in food consumption, change in housing environment and change in decision-making ability of the credit receivers after their involvement in BRAC micro credit program. Attempts were also made to describe some of the selected characteristics of the women beneficiaries and their relationships with the impact of BRAC micro credit program. The income, food consumption, housing environment and decision-making ability of the credit receivers increased significantly after their involvement with BRAC micro credit program. The average annual income, per capita daily calorie intake, housing environment and decision-making ability score of the respondents increased at 5.03 thousand taka, 218.90 kilo calories and 9.56 and 1.81 respectively after involvement with BRAC micro credit program. Before involvement 35 percent of the respondents had Kutcha Ghar with tin roof, but after involvement the percentage was 60. Nineteen percent of the respondents used half sanitary toilet before involvement where as after involvement this percentage turned into 34 percent. Before involvement with BRAC micro-credit program 31 percent of the respondents' families had own tube well but after involvement in the program this percentage raised to 54. The education, farm size, cosmopoliteness credit received, and attitude towards BRAC micro credit program had significant relationship with the impact of micro credit program. However, age, family size and duration of involvement with BRAC micro credit program of the respondents did not show any significant relationship with the impact of BRAC micro credit program. High rate of interest identified as the main problem of the respondents.
