Changes in Land Use and Land Cover, Normalized Difference Vegetation Index and Land Surface Temperature in the Narsingdi District During 2001 to 2021

Rapid urbanization and industrialization cause land use changes, reduce green spaces, and increase the land surface temperature. Green spaces of a city area maintain environmental quality by absorbing air pollutants and reducing land surface temperature. The present study aimed to detect the changes in land use and land cover (LULC), normalized difference vegetation index (NDVI), and land surface temperature (LST) in the Narsingdi district including six Upazilas from 2001 to 2021. The Landsat 7- Enhanced Thematic Mapper Plus (ETM+), the Landsat 8- Operational Land Imager (OLI) imageries and the Moderate Resolution Imaging Spectroradiometer (MODIS) data were used to analyze the LULC, NDVI, and LST by using Google Earth Engine (GEE) and ArcGIS 10.8.2. The images were analyzed into four land use classifications – agricultural land, built-up area, forest vegetation, and water body. Among all the Upazilas, Narsingdi Sadar was the vulnerable area, where agricultural land, forest coverage, and water body decreased significantly by 6.67%, 2.2%, and 4.66%, respectively. The built-up area increased by a considerable amount of 13.53% during the last twenty years. The forest coverage of Narsingdi Sadar Upazila was calculated at only 8.91% in 2021 and decreased from 11.11% in 2001. The NDVI values surprisingly increased in all the Upazilas, but in Narsingdi Sadar, it is comparatively low (0.08) than in other Upazilas. The increasing trend in LST in the Narsingdi Sadar Upazila is alarming, 1.14oC from 2001 to 2021 (0.57oC/decade). The significant changes in LULC, NDVI, and LST made the Narsingdi Sadar a more critical area in the Narsingdi district. The findings of the study will be helpful to policymakers in making appropriate decisions in future city development. J. of Sci. and Tech. Res. 5(1): 93-118, 2023

Study about Nutraceuticals and its Usage among General People in a District of Bangladesh

Consumers' health is impacted by nutraceuticals in a variety of ways biochemically. Beyond their basic nutritional roles, nutraceuticals offer additional advantages. Identifying nutritional deficiencies from other physiological effects, like lowered disease risk, is crucial. Herbal supplements, refined foods, genetically modified foods, and dietary supplements are examples of nutraceuticals. A nutritional supplement survey was conducted in a few areas of the Narsingdi district. In total 210 men and women were enlisted, and the majority of them underwent methodical in-person interviews. This study's main objective was to determine how much knowledge and usage of nutritional supplements there was among people living in rural and urban areas. All findings are presented and clarified in result and discussion section. In summary, this study broadens the current understanding of the pattern of nutraceutical use among Bangladeshi urban and rural populations.

Study of the dyeing industry pollution after mandatory installation of ETP in Madhabdi municipality, Bangladesh

ABSTRACT Madhabdi municipality of the Narsingdi district of Bangladesh, the “Manchester of the East,” is famous for its cloth market and fabric dyeing industries. The untreated effluent discharge has been mixed with the water and soil, degrading the environmental standards of this area for years. Installing an effluent treatment plant (ETP) in all textile industries in Bangladesh is mandatory. This study evaluates the soil condition, surface water quality, and heavy metal contamination in cultivated vegetables after the compulsory installation of ETP. Soil and water samples from eight locations and cultivated vegetable samples from three locations are collected and analyzed for this study. The pH, EC (electric conductivity), TDS (total dissolved solids), DO (dissolved oxygen), and heavy metal concentrations are observed. The water quality index, contamination index, metal evaluation index, pollution load index, and metal pollution index are calculated from the collected samples. The study found that the physico-chemical properties of water pH (9.19), EC (2232.38 µScm-1), and DO (0.79 mgL-1) violate the national standards. The mean TDS is below the maximum permissible level. The heavy metal concentrations of Cr and Pb in water are 1.03 and 0.13 mgL-1, crossing the permissible limit, respectively, but Mn, having 0.89 mgL-1, is within the limit. The water quality is unsuitable for domestic and agricultural use, contamination is “medium,” and metal evaluation is “medium.” The soil is alkaline, having a pH of 8.58. The soil’s Cr, Pb and Mn concentrations are 68.21 µgg-1, 52.73 µgg-1and 805.16 µgg-1, respectively. The soil contamination level is low to moderate. Cultivated leafy vegetables have a concentration of Cr, Pb and Mn; 2.61 µgg-1, 0.30 µgg-1and 288.67 µgg-1, respectively, where Cr has crossed, Pb is within, and Mn is lower than the permissible limit. Produced vegetables have high (12.10–33.09) MPI (metal pollution index) and are at a high-risk level for consumption as food.

Prevalence of malnutrition in children in Narsingdi district, Bangladesh: An observational study

Background: A pathological condition called malnutrition arises when there is a relative or absolute lack or excess of one or more nutrients. In low-income nations, it is a serious public health issue for children under ten years. Malnutrition is a state of nutritional deficit brought on by insufficient consumption of protein or energy. Primary acute malnutrition in children is a prevalent condition in underdeveloped nations due to insufficient food supply resulting from social, economic, and environmental causes. An underlying illness that results in aberrant nutritional loss, increased energy expenditure, or decreased food intake is typically the cause of secondary acute malnutrition. Method: This was an observational, descriptive study conducted in Bangladesh's Narsingdi area from September to October 2023. All records of children with complications of malnutrition, between the ages of 2 and 10 were included in the study. Result: 142 children fall in the category of underweight, 166 children possess suitable BMI and 8 of them were heavyweight with BMI more than 23. Nearly one third of the children faces physical problems some times in their life time. Among all of the children 139 (43.98%) had perfect physical status with good health and diarrhea is the most common problem they caught by 118 respondents. Conclusion: In the district, its severity and prevalence can be decreased with increased community knowledge and stronger preventive efforts.

Similar to the rest of the world, Bangladesh has been affected by the current and ongoing pandemic COVID-19 crisis. Small and medium enterprises (SMEs) are the fundamental economic pillar for business development in Bangladesh. The main purpose of the research paper is to determine the post-COVID challenges and opportunities on SMEs in Bangladesh. Before staring the pandemic situation, the main barriers to the establishment of SMEs included access to formal credit, a lack of qualified labor, high operational costs, poor product quality, a lack of financial literacy, etc. SMEs are experiencing a capital constraint, increased operating costs, and employee layoffs as a result of this global epidemic. Both primary and secondary data are conducted to identify the findings of the study. Statistical analysis has been conducted by using the Microsoft Excel software. Sample size is 300 respondents from the study area (Dhaka and Narsingdi District) in Bangladesh. The findings of the study are that 52% of businesses have completely shut down its operation because of COVID-19. Moreover, 78% people in Bangladesh enable to run business activities on online platform that is possible only for COVID-19 problems, otherwise, people are unwilling to accept technology. To keep SMEs in business, emphasis must be placed on using government stimulus monies properly. Moreover, the real possibilities and opportunities of Bangladesh remain in the SMEs and therefore the sector should get more concentrating on the sustainable growth and development of the country through overcoming the pandemic COVID-19.

Analysis of organophosphorus pesticide residues in selected vegetables purchased from Narsingdi district of Bangladesh using QuEChERS Extraction

Pesticide residues in different crops, including food grains and vegetables are burning issues in Bangladesh. Therefore, the present study was conducted to analyze organophosphorus pesticide residues in three popular vegetables (cauliflower, hyacinth bean and yard long bean) collected from five local markets of Narsingdi district of Bangladesh. The collected vegetable samples were extracted and cleaned up using Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction technique and analyzed by Gas Chromatography (GC) equipped with Flame Thermionic Detector (FTD). A total of 45 vegetable samples were analyzed. Among the 15 analyzed samples of hyacinth bean, three samples (20 % of the total samples) contained pesticide residues above the EU-MRL and the remaining samples did not contain any detectable residues of the selected organophosphorus pesticides. In case of cauliflower, out of 15 analyzed samples, two samples (13% of the total number of samples) contained pesticide residues above the EU-MRL. In case of yard long bean, of the 15 analyzed samples, four samples (27% of the total number of samples) contained pesticide residues above the EU-MRLs. This study reveals the present status of pesticide residue contamination in the selected vegetables. Asian Australas. J. Biosci. Biotechnol. 2022, 7 (3), 114-121

Profitability Analysis of Cultivation of Banana Cultivars Sabri and Sagar in Some Areas Of Narsingdi District

An attempt was made to investigate the input use pattern, profitability and factors affecting the banana cultivation. A total of 60 banana growing farmers taking each 30 Sabri and 30 Sagar growers were selected from Narsingdi district for collecting data using a pre-tested interview schedule during mid-September to mid-October, 2019. The study revealed that farmers used almost all types of inputs like human labour, organic and inorganic fertilizers, pesticides, and irrigation water in banana cultivation. The cultivations of both Sabri and Sagar variety were highly profitable at farm level since the net returns (Tk.4,29,280/ha and Tk.2,73,995/ha) and BCRs (2.66 and 2.05) were very high. The coefficients of production function revealed that banana sucker, land preparation and Muriate of Potash (MoP) fertilizer positively influenced the yield of Sabri variety banana, whereas only MoP influenced the yield of Sagar variety. The major problems of banana cultivation were lacking of skilled labour, attack of diseases, and high price of fertilizers.

Improvement of Soil Fertility Through Jackfruit-Based Multistoried Agroforestry Practices in Terrace Ecosystem

This study aimed to evaluate the soil chemical properties of a jackfruit-based multistoried agroforestry system of a farmer’s field in Belabo upazila of Narsingdi district located in the central terrace ecosystem of Bangladesh. The three-storied of crops viz. upperstorey - jackfruit trees; middlestorey - papaya, lemon, mandarin and sweet orange and lowerstorey - seasonal vegetables such as eggplant, bottle gourd and ash gourd were included in the system. The experiment was conducted in a randomized complete block design with three replications. There were five treatments covering agroforestry with four orientations and sole cropping (jackfruit trees). The agroforestry system improved the chemical properties of top soil layer compared to the sole cropping with jackfruit trees. Soil pH (4.62), total nitrogen (0.081%), organic carbon (0.61%), organic matter (1.05%), phosphorus (4.23 ppm), sulphur (10.17 ppm), calcium (2.27 meq/100g), magnesium (0.46 meq/100g) and potassium (0.52 meq/100g) were recorded in the agroforestry systems that were higher than those of the soil properties of sole cropping (jackfruit trees). The result revealed that practicing agroforestry can help in improving the soil fertility status for successful sustainable crop production. Ann. Bangladesh Agric. (2021) 25 (1) : 105-115

Heavy Metals in Widely Consumed Vegetables Grown in Industrial Areas of Bangladesh: a Potential Human Health Hazard.

The prevalence of heavy metals in frequently consumed vegetables constitutes a considerable public health hazard. This study aims to determine the quantity of heavy metals in widely consumed watercress (WC), alligator weed (AW), red amaranth (RA), spinach (SP), cauliflower (CF), and eggplant (EP) cultivated in industrial areas (e.g., Narsingdi district) of Bangladesh to assess the potential health hazards. Atomic absorption spectroscopy (AAS) served to determine the concentrations of lead (Pb), cadmium (Cd), chromium (Cr), and nickel (Ni) in vegetable samples (n = 72). The contents of Pb, Cd, Cr, and Ni were found in most of the analyzed vegetables, whereas 79.17%, 44.44%, and 1.39% samples exceeded the FAO/WHO maximum allowable concentration (MAC) for Pb, Cd, and Ni, respectively. The estimated daily intake (EDI) of single heavy metal was below the corresponding maximum tolerable daily intake (MTDI). The incremental lifetime cancer risk (ILCR) values of Cd in all samples exceeded the threshold limit (ILCR > 10-4) for both adults and children, indicating lifetime cancer risk due to the consumption of contaminated vegetables. The target hazard quotient (THQ) of each heavy metal was THQ < 1.0 (except Ni in few samples), indicating that consumers have no non-cancer risk when exposed to a single heavy metal. However, hazard index (HI) values of heavy metals were greater than unity in contaminated WC and AW for adults and children. Meanwhile, WC, AW, and SP samples for children emerged as potential health risks of inhabitants in the studied areas. The outcomes of the present investigation might assist the regulatory bodies concerned in setting new strategies through monitoring the quality of marketed vegetables to minimize the risks to humans.

Status of disease prevalence, drugs and antibiotics usage in pond-based aquaculture at Narsingdi district, Bangladesh: A major public health concern and strategic appraisal for mitigation

This research aimed to investigate the present status of disease prevalence and usage of aqua drugs for various aquaculture operations in the Narsingdi region of Bangladesh. Data were collected through the market survey, preset questionnaire interview, personal contact, and participatory rural appraisal tools. Amongst the respondents, the maximum percentages were found practicing mixed cultures of carp, tilapia, and pangas. The respondents suggested that epizootic ulcerative syndrome, saprolegniasis, streptococcosis, tail and fin rot and bacillary necrosis are common fish diseases in the area. About 140 drugs of different companies used in aquaculture for different purposes such as disease treatment, growth enhancement, water quality improvement, toxic gas removal, improvement of feed conversion ratio. Zeolite, rotenone, disinfectant, oxygen precursors, ammonia reducers, and probiotics were applied for pond preparation, water, and soil quality maintenance, while 30 different antibiotics were used for the purpose of treatment. Among the available antibiotics, oxytetracycline, ciprofloxacin, enrofloxacin, erythromycin, sulphadiazine, and trimethoprim were found extensively used by the fish farmers. Four enzymes and eighteen growth promoters were identified as being utilized to enhance digestion and boost up the production. This study elicited various issues connected with application and administration of such aqua chemicals, including farmers’ ignorance about their usage, proper doses, application methods, withdrawal period, and the human health concerns associated with their irresponsible use. However, the consequences of these chemical products to the environment, animal health, and human health required further study for the betterment of mankind.

Yield gap in bitter gourd production: A perspective of farm-specific efficiency in Narsingdi district in Bangladesh

The concept of yield gaps arose from IRRI experiments undertaken in the 1970s. The yield gap in this study refers to the discrepancy between prospective farm yield and actual average farm yield. This study aims to find the yield gap by studying the efficiency, abiotic and biotic factors. Simple random sampling techniques were used to collect data, and a total of 72 respondents were interviewed for this purpose. The study revealed that 90.70%, 80.30%, and 73% of farmers were technical, allocative, and cost-efficient for bitter gourd production. The yield gap was 15, 245 kg/ha due to the non-transferable component of technology, whereas 3914 kg/ha was due to existing inefficiency at the farm level. Moreover, combined biotic and abiotic factors were responsible for the 19.91 percent yield loss, constituting a mean yield gap of 6598 kg/ha. Low price of bitter gourd, high labor wage rate, and high input price was the main socio-economic constrain for improving bitter gourd production where excessive rainfall, attack by insect and disease, lack of quality seed, and lack of proper utilization of irrigation facilities were identified as main biophysical constraints for bitter gourd production. Government intervention by providing training, maintaining an effective marketing system, and ensuring quality input can greatly remove the problem mentioned by farmers.

The data were collected from 75 contract farmer and 125 non-contract farmer of Shibpur upazila. Binary logistic regression was used to analyze fifteen factors that potentially affected farmers’ decision to participate in CF and descriptive statistics were used to analyze the socio-demographic profile of the farmer.&#x0D; Results: The study found that farmers education, wife’s occupation, family size, labor, fertilizer use, training, savings and income were the significant factors in the model and farmers occupation, other family member's occupation, income source, land type, size of land, experience and storage place were non-significant predictors using P&lt;0.01 and P&lt;0.05 threshold.&#x0D; Conclusion: Farmer’s education, female head's occupation, family size, land type, size of land holdings, labor use, type of fertilizers being used, training or technical knowledge and average monthly income of the respondents had a positive influence on farmer’s decision.

Status of feeding practices, productive and reproductive performances of dairy cows at the Palash Upazila of Narsingdi district in Bangladesh

This study was carried out at different villages of Palash Upazila under the Narsingdi district in Bangladesh to envisage the storage system of straw, feeding system, genotype distribution, productive and reproductive performances of dairy cows. Hence, a total of 100 small-scale dairy farm owners were randomly selected and interviewed with a pre-tested structured questionnaire. Overall, 40% of farmers were raised indigenous cows in the studied villages, while 60% were reared Holstein crossbred cows. Around 75 and 25% farmers were collected green grass from the arable and non-arable lands, respectively. Results revealed that 11.43% farmers from each village of Balucharpara, Kandapara, Gazaria, Sultanpur, and Malita were stored straw as a stack on the field, and the lowest percentage (4.29%) farmers of Sanerbari village were followed this system of storage. About 14.81% farmers of each Paiksha and Sanerbari villages were stored straw inside their houses. Calving interval (P=0.04) of indigenous cows and milk yield (P=0.05) of Holstein crossbred cows were both differed significantly among the studied villages. Overall, both indigenous and Holstein crossbred cows performances were observed better in Balucharpara village than that of other villages. However, farmers should be motivated and given training on fodder cultivation, feed processing, and preservation to accelerate the sustainable production and reproduction of cows.

Fish Biodiversity Assemblages and Fishing Gears Used at Chinadi Beel in Narsingdi District of Bangladesh

The present survey disclosed the available fish biodiversity and the gears used for fishing in the Chinadi beel, Narsingdi, Bangladesh, for a certain period. Data was collected through face to face conversations using a well-structured questionnaire and cross-checked. About 51 species of fish under 7 orders and 19 families were found. The dominant order was found jointly for Cypriniformes (29.41%) and Siluriformes (29.41%). About 39 least concern (75%), 5 vulnerable (9.62%), 6 near threatened (11.54%), and 1 not evaluated (1.92%) species were observed. Fifteen different types of fishing gears (8 major categories) are used for fishing by the fishermen, of which seine net was the most leading gear. Most of the gears are banned for a period due to its unauthorized mesh size. The price of fishing gears was ranged from 250-1,00,000 Tk, of which the highest price was for seine net. The uppermost catch per unit effort (CPUE) was found for ber jal that was 15-18 kg/day. Most of the fishing gear was operated throughout the year, but limited in the dry season. However, the variety of fish abundance and species diversity is declining day by day in this beel. To protect the fish diversity of the Chinadi beel, it is recommended to establish effective fishery management practices, monitoring overfishing, and awareness of fishermen is highly recommended.
