Land use and transport integration has been highlighted as one of the most important policy objectives considering the interrelationship between the two concepts and can be used as a means of planning through intervention. From the standpoint of revealing the interplay, the study's objective is to assess the land use change of Dhaka City Corporation Area and determine its impact on transportation to assist the national policymaking and achieve Sustainable Development Goals (SDGs). The methodology directed the determination of the land use change from 2010 to 2018, and then the consequent change in traffic flow while the necessary data in this regard were collected from secondary sources. The study shows that mixed-use development generates fewer trips. This is the study's finding in regard to integration among the national policies regarding land use and transport planning. This study is a methodological approach to analyse the impact of land use change on transportation and can be a role model for solving complex urban problems, e.g., traffic congestion by integrating the Land Use-Transport interaction. The study provides a background of the policymakers in their policymaking process, and an integrated policy will enable the nation to fulfil its Sustainable Development Goals.

The Social–Environmental System (SES) framework is crucial in understanding the intricate interplay between human societies and their environmental contexts. Despite its significance, existing SES delineation methods often rely on subjective judgment and struggle with the non-linear, multi-scale nature of SES data, leading to challenges in effective resource management and policymaking. This research addresses these gaps by proposing a novel, reproducible framework for SES boundary delineation that integrates both vector and raster data, utilizing advanced spatial optimization techniques and dimension reduction algorithms like UMAP to manage the non-linear characteristics of SES. The framework also leverages the SKATER algorithm for precise regionalization, ensuring spatial continuity and compactness while allowing user control over region selection and data dimensions. Applied to the Rio Grande/Bravo Basin, this approach demonstrates the practical utility and computational efficiency of the proposed method, offering a scalable solution adaptable to various regions. While focusing on this transboundary area, the study underscores how its framework can be generalized globally for addressing socio-environmental challenges while maintaining flexibility to accommodate local and regional specificities. The framework’s reliance on open-source tools further enhances its accessibility and reproducibility, making it a valuable contribution to SES research and practical environmental management.

Social safety, security, and comfort of school-going children during the travel time to school becomes a subject of anxiety to the parents and is a crucial issue in recent times. In this regard, community-based transport can be a significant way to address social security issues in travel at a reasonable cost and reduce the burden on private mode. In Dhaka city, school van service already exists but due to some sort of problems the service has not been proved an efficient and formal mode of transport for solving mobility problems. This study seeks to identify the existing problems and prospects of the school van service and provide a unique, healthy, safe, and reliable transport mode for children. Applying different tools of the Participatory Rural Appraisal (PRA) method, the problems and solutions have been drawn from the community. The recommendations of this study will help the school van services (a community-managed para-transit system) to be more functional in playing a vital role in solving the problems of short-distance travel. This service has great potentialities to be adopted in other trips such as trips to and from offices which will lessen the road congestion at the peak periods.

Economic development and regional integration are prerequisites for a country’s overall economic and regional growth. Nevertheless, like many other developing countries, Bangladesh is facing a problem of unsustainable economic growth. A lack of organized development planning, along with unstable and insecure employment sectors, have created poverty prone underdeveloped and disintegrated regions in the country. Regional development is a means of reducing regional disparities by supporting employment and wealth generating economic activities across different regions in an economy. It involves a study of a region as a structural or dynamic system, with the interaction of different social and cultural units. This study centers on developing a generic methodology to enable such a regional analysis using shortrun econometric methods.
