The study has been conducted at USA Agro and Auto Bricks Ltd. at Lebukhali, Dumki Upazila under Patuakhali district. The purpose of this study is to find out the potential environmental impact during the construction operation and maintenance phase of the project and suggest effective mitigation measures to reduce negative impacts. Data necessary for the study has been collected through both primary and secondary data sources by literature review, Household Questionnaire Survey, Focus Group Discussion, and Key Informant Interview of surrounding people. Environmental Impact is analyzed through the calculation of Environmental Impact Value and Leopold matrix. Environmental Impact Value (+2) shows that the impact of the brickfield is low positive. Leopold matrix shows the pre, during and post construction value as 2.28, 1.56 and 1.82 where pre-impact is moderate, during and post-impact is low. Our estimated result shows that the negative impact of the project is minimum. J. Environ. Sci. & Natural Resources, 11(1-2): 87-95 2018

Adoption of organic farming has been increased which have a reduced impact on environment. An experiment was conducted at the Landscaping section and Laboratory of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh for optimisation of growth, yield and quality of strawberry cultivars through organic farming during the period from October 2017 to March 2018. The experiment comprised two cultivars viz., RU-1 (Festival) and RU-2 (AOG), and eight organic manures viz., control, cowdung, mustard oilcake (MOC), poultry manure, cowdung+MOC, cowdung+poultry manure, MOC+poultry manure, cowdung+MOC+poultry manure. The two-factor experiment was laid out in randomised complete block design with three replications. Significant variation was observed between strawberry cultivars and organic manures in all the parameters studied. Highest growth, yield and quality characters were obtained from Festival except number of runner per plant and TSS content with AOG. Combined application of cowdung+MOC+poultry manure gave the maximum yield (19.14 t/ha) than the other treatments. J. Environ. Sci. & Natural Resources, 11(1-2): 121-129 2018

Tangail district has undergone dramatic changes in its physical form through urbanization. Here, agricultural land and vegetation cover have been transformed into built-up areas; fallow land and water bodies into reclaimed built-up areas. The aim of this research was to develop land use and land cover (LULC) maps of the Tangail Municipality area in 2001, 2011 and 2017. Landsat (TM) Satellite images of the year 2001, 2011, and 2017 were used. On-screen digitization method was applied to prepare the final maps with four classes (water bodies, vegetation, agricultural land, and settlement area) of land use. The study reveals that the settlement area was increasing over the study period, and mainly agricultural land and water body were converted into settlement. It was found that about 48.73% areas were covered with the settlement area in 2017. Similarly, a substantial increase was seen in the areas of vegetation as about 824.49 ha land added to this category throughout the study years. In contrast, the agricultural land (786.30 ha) and water body (114.73 ha) were declined between 2001 and 2017. J. Environ. Sci. & Natural Resources, 11(1-2): 245-252 2018

Cadmium (Cd) is a heavy metal which is not essential for human body. Cadmium enters into human body mainly through food consumption. Besides industrial wastes, phosphate fertilizers contain Cd which accumulates gradually in agricultural lands. To produce high quantity of food for about 160 million people of Bangladesh, agricultural lands need to be applied huge amount of fertilizes including TSP which add Cd to soils. It has been reported that in rice grains the cadmium concentrations were the highest in Bangladesh and Srilanka where the per capita rice intake is high, from a survey on four continents of 12 countries. The intake of these Cd containing foods may ultimately increase the Cd concentration in human kidneys and livers which might be related to the enhanced kidney patients in Bangladesh. There is lot of toxic effects of excess Cd on humans. The present review illustrates the urgency of further studies of Cd in Bangladesh. J. Environ. Sci. & Natural Resources, 11(1-2): 227-234 2018

The present study was conducted to carry out a comparative study on farm materials (water, soil, feed) and the quality parameters of pangus (Pangasianodon hypophthalamus) of five different farms in Trishal area under Mymensingh district. The study was carried out during May-June, 2016. Most of the pangus farmers used homemade or farm made supplementary feeds for pangus culture The percent moisture, protein, lipid and ash content in fresh fish ranged from 77.05 to 78.79, 14.21 to14.84, 3.55 to 4.49 and 2.03 to 2.67 whereas after 24 hrs of death of fishes, these percent values changed as 77.05 to 78.79, 14.21 to14.84, 3.55 to 4.49 and 2.03 to 2.67. Slight changes observed in different quality parameters in the fish samples 24 hrs after death as dead fishes were preserved at chilling temperature in a homestead refrigerator till analysis. Therefore, the study could be concluded that- though the values for different parameters of farm materials (water, soil, feed) and quality parameters of fish samples differed but was mostly not significant. The differences observed in the parameters might be due to the variations in management techniques of each farm. J. Environ. Sci. & Natural Resources, 11(1-2): 109-119 2018

The experiment was conducted at Cotton Research, Training and Seed Multiplication Farm, Jagodishpur, Chowgacha, Jessore initiated June 19, 2015 for the cropping season 2015-16 to observe the performance of cotton based cropping system including total three crops in a year. The other crops were i) relay wheat – mungbean and ii) relay lentil – mungbean. Four cotton varieties CB-12, CB-13, CB-14 and CB Hybrid-1 were sowed in a RCBD design with three replications. Seed cotton yield was significantly different among the varieties. The highest seed cotton yield (2519.3 kg/ha) was obtained from CB Hybrid-1 and the lowest (2112.37 kg/ha) seed cotton was produced by CB-13. The highest BCR (1.31) was observed in cotton (CB Hybrid-1) –relay lentil –mungbean cropping pattern and the lowest BCR (1.10) was observed in Cotton (CB-13) – relay wheat –mungbean cropping pattern. The finding infers that cotton – relay lentil - mungbean cropping pattern might have the potentiality to increase cropping intensity in Bangladesh. J. Environ.

Rice bran, a milling byproduct of rice is rich in nutrients especially high in fiber and protein in comparison with white wheat flour-which is predominantly used for bread production. Inclusion of rice bran with wheat flour was expected to induce nutritional value of bread positively. Two form of rice bran sample both full fatted and defatted were incorporated with wheat flour in a proportion of 0%, 5%, 10% and 15% respectively to develop composite bread. Physical, chemical, and sensory evaluation was carried out to determine the quality of different composite breads. Bread weight didn’t differ statistically though there was a marginal declination of volume for bread with the increase of the percentage of rice bran. The percentage of protein and fiber was increased rationally as expected. A level of 10% rice bran added to bread was regarded to yield good sensory quality. J. Environ.

The study was conducted to assess the effect of formulated feed on the growth performance of prawn both in aquarium and pond system during 25 September to 25 December 2013. The feeds/diets were, diet 1 (formulated feed), diet 2 (commercial feed), diet 3 (custard cake) and diet 4 (shuji-ata ball). Protein percent of the feeds were 34.51% in Diet-1, 32.67% in Diet-2, 25.41% in Diet-3 and 21.43% in Diet 4. Four experimental diets were assigned to four treatments viz. T1, T2, T3 and T4 both in aquarium and pond. The water quality parameters were monitored 15 days interval and the ranges were: temperature 26°C to 29.8°C (aquarium system) and 24.5°C to 29.9°C (pond system) ; pH 7.07 to 8.09 (aquarium system) and 7.87 to 8.45 (pond system); DO 7.07 to 8.09 (aquarium system) and 5.08 to 5.86 mg/L (pond system). The result of the present study showed that Prawn feed Diet 1 and Diet 2 resulted highest weight gain 2.42 and 2.39 g (aquarium system) and 3.63 and 3.5g (pond system), respectively. Based on the result of present study, it could be suggested that shrimp waste can be replaced in the diets of prawn (Macrobrachium rosenbergii) along with other ingredients. J. Environ.

The water quality parameters were monitored 15 days interval and the ranges were: temperature 26°C to 29.8°C (aquarium system) and 24.5°C to 29.9°C (pond system) ; pH 7.07 to 8.09 (aquarium system) and 7.87 to 8.45 (pond system); DO 7.07 to 8.09 (aquarium system) and 5.08 to 5.86 mg/L (pond system). The result of the present study showed that Prawn feed Diet 1 and Diet 2 resulted highest weight gain 2.42 and 2.39 g (aquarium system) and 3.63 and 3.5g (pond system), respectively. Based on the result of present study, it could be suggested that shrimp waste can be replaced in the diets of prawn (Macrobrachium rosenbergii) along with other ingredients. \u0000J. Environ.

The study has been carried out in a Riverine Island of the Ganges River in Chapai Nawabganj District of Bangladesh to evaluate the livelihood status and the association between different livelihood capitals and well-being status. Both qualitative and quantitative data are collected through household questionnaire survey and field observation. Most of the surveyed households are found either poor or hard core poor. This study identified five capitals of livelihood i.e. human, social, natural, financial and physical capitals with specific indicators. Family size and education indicators of human capital, organizational attachment of social capital, total and operational land of natural capital, value of livestock, size of savings and loan of financial capital and mobile phone of physical capital are statistically significant with the well-being status. This means higher value of indicators indicate higher the well-being status. Hence, this study assumes that most of the char dwellers are poor or hard core poor because their livelihood capitals and assets are not in satisfactory level. This study suggests providing necessary institutional and organizational supports for strengthening the livelihood of char dwellers. J. Environ. Sci. & Natural Resources, 11(1-2): 27-36 2018
