The economic trend of a region plays a crucial role in the overall development and growth of a nation. This paper aims to assess the impact of different industries on the economic trend of the Dhaka region in Bangladesh. Specifically, it focuses on determining the contribution of regional GDP to the national GDP through various industries. To achieve the aim, this study employs a short-run and a long-run approach of regional economic structure analysis. The short-run analysis allows for an examination of the immediate impact of industries on the Dhaka region's economic trend. On the other hand, the long-run analysis considers the sustained effects of industries over an extended period. Data for this research paper were collected from government reports, statistical databases, and are industry specific data. The analysis encompassed a wide range of sectors such as manufacturing, services, agriculture, and construction, among others to do short run and long run analysis by calculating economic base multiplier, national share, industry mix shift share and regional shift share. The results of this study provide a comprehensive understanding of the industries that have a substantial contribution to the economic trend of the Dhaka region. Furthermore, it provides insights into the extent of the region's impact on the national GDP through these industries as it determines regionally and nationally fast or slow growing industries. The findings from this research demonstrate that Dhaka Region’s industries contributed 19% of the national GDP in 1999–2000, showcasing its economic importance which outpaced national average growth of industries but faced challenges in some sectors. This study sheds light on the short and long-term impacts of different industries on the economic trend of the Dhaka region in Bangladesh.

The paper examines the relationship between income inequality and economic growth in Bangladesh, focusing on urban-rural disparities, sectoral changes, and policy interventions. It assumes an inverted U-shaped relation between inequality and growth while debating the Kuznets Curve and the role of human capital in mitigating inequalities. The paper finds that while inequality may stimulate industrial growth in urban areas, rural areas face barriers to access to capital, education, and infrastructure resources. This restricts rural economies’ participation and widens inequality. The Gini coefficient has increased from 0.33 in 1991 to 0.49 in 2020, indicating that urban-based inequality is related to industrial growth, but benefits are not realized equally. By reviewing a total of 30 studies to analyze the relationship, this paper calls for a multidimensional policy approach that addresses disparities, improves infrastructure, and fosters inclusive growth through investments in education, technology, and financial inclusion. Further research should be undertaken on how climate change, digital transformation, and sector-specific policies may impact the economy in terms of inequality and sustainable growth

Regional GDP framework analysis is the fundamental concern of regional planning. Regional GDP evaluates the regional economic structure. Regional economic structures can be conducted through short-run and long-run approaches. The study aimed to analyze the Mymensingh and Jamalpur districts' economic structure in the short run and long run. The study interpreted the region's overall economic structure through basic and non-basic activities, and also showed the contribution of the current regional GDP to the national GDP, and simulated the scenario. Traditional methods, e.g. Location Quotient and Shift-share analysis were blended to form a hybrid methodological structure to assess a local economic structure. National and regional aggregated data of GDP at constant prices between two fiscal years, 1995-96 and 1999-2000 was equipped as the basis for analyzing the economic structure. The study found the national share was positive (+29407.30349) for all the sectors and industries (+1005.901448) in those regions that were nationally fast-growing. As the magnitude of regional shift means the region was negative (-1658.204939), industries in this region were considered regionally lagging industries. The overall trend line analysis of the multiplier showed that the region's basic activity is increased from its base to terminal year but with the change of year, the scenario fluctuates. The article finally explained the scenario through sector theory. The paper will be helpful to take any initiatives nationally and also helpful for the policy maker, urban planner, economist, other scholars, and researchers to make any decision over the area.

Effective waste management in the maritime industry is crucial for mitigating environmental impacts and promoting sustainability. This study compares waste management practices between foreign ships and local vessels visiting the Mongla Port area in Khulna, Bangladesh. The assessment involved ten foreign ships and 100 local vessels, utilizing surveys and on-site visits to reveal distinct waste management strategies. Waste bins were distributed on local vessels and collected from 25 local vessels and three foreign ships. The collected waste was analyzed using a sieve and modular screen methods. Data on waste collection by ship chandlers from foreign ships were obtained through the Mongla Port Authority. Findings indicated that foreign ships demonstrated efficient waste management, with only 38 foreign ships relying on ship chandlers for waste collection, while 96.5% to 97.67% accessed waste facilities from other ports like Chittagong. Compliance with MARPOL Annex regulations was consistent among foreign ships. In contrast, local vessels from Bangladesh lacked regulatory frameworks for waste management. Practices varied, with some vessels implementing waste segregation while others lacked proper separation methods. Several local vessels engaged in plastic waste recycling, but inconsistent reporting hindered the assessment. Despite lower plastic waste generation rates on local vessels (4.13 gm/capita/day) compared to foreign ships (154 gm/capita/day), their waste disposal practices raised environmental concerns. This comparative analysis underscores the need for enhanced waste management infrastructure and practices among local vessels. Urgent interventions are essential to promote environmental preservation and sustainability in the maritime industry. The BIWTA and all the corresponding officials, port authorities, and crew members of local ships must take the necessary steps to make waste management sustainable and environmentally friendly.

Wildfire activity has become one of the most sensational and urgent issues in the United States after the Tornadoes event. Overviewing the chronological data of the past 24 years, it has been observed that wildfires have increased in severity, frequency and intensity, posing serious detrimental impacts on the health of humankind, and ecological disturbance. This research analyzes wildfire occurrence data across California from 2000 to 2023 using Geographic Information Systems (GIS) to identify patterns of wildfire activity, mapping affected areas focused on land and forest. It also highlights the correlation between wildfires and PM2.5 & ozone pollutants to measure the Air Quality Index (AQI).
