A political ecology of aviation and development: an analysis of relations of power and justice in the (de)construction of Nepal's Second International Airport

In this article, we investigate socio-ecological conflicts surrounding the proposed Second International Airport project near Nijgadh, a town in the southern Terai region of Nepal. Praised by the Nepali government as a gamechanger for Nepal's economy, it has come under scrutiny by environmental activists after plans emerged for extensive clearing of the densely forested project site. While public and political debates have focused on the environmental impacts of the project, the area is also home to nearly 8,000 people, most of whom have no formal land rights and belong to Janajati groups, who face displacement. The apparent lack of attention to the project's consequences for local communities raises questions about the safeguarding of their interests. Drawing on justice theories and political ecology, we conducted a case study to investigate the residents' struggle for justice, recognition, and visibility amidst a strong dichotomy of mainstream developmentalist and conservationist discourses. During two months of fieldwork in Nepal, we gathered empirical evidence, including observations, interviews, and project documentation. Our findings suggest that the misrecognition of local communities, particularly in Tangiya Basti, began long before the airport project, and is intertwined with distributive and procedural injustices, reinforced by power asymmetries of various kinds. Overall, we argue that while the airport project is often framed as an environmental conflict, it is also a conflict over claims to social justice and livelihood security.

Compensation for Land Acquisition for Public Interest Islamic Law and Agrarian Law Perspective (Case Study in the Yogyakarta International Airport Mega Project)

In general, this study examines the issue of compensation for land acquisition for the public interest in the view of Islam and Agrarian law. While empirically, this study examines the implementation of compensation for land acquisition for the public interest in the Yogyakarta International Airpot Airport project from the perspective of Islamic law and agrarian law. This type of research is library research, namely research whose main objects are library books and other literature, which are related to the title above. So this research is a qualitative research. However, this research is strengthened by research data in the field (file research). In this study, researchers tried to examine and view the law with a complete picture. And to realize it, it must always be carried out in an interdisciplinary manner, where law is a symptom of two aspects, namely normative (das sollen) and empirical (das sein). Therefore, this research is not enough to only use library research, but rather a combination of library research with research surveys in the field. Thus the approach method used is normative juridical and sociological juridical, with descriptive-qualitative research specifications. In connection with this research is empirical legal research, the data sources used are the primary data sources and secondary data sources.

Influence of Clay Fraction and Mineral Composition on Unsaturated Characteristics of Cohesive Foundation Soil in Airports

Taking unsaturated clay foundation soil of an airport project in Hefei as the research object, the effects of particle gradation and mineral composition on the unsaturated soil properties were analyzed through two kinds of tests. The results show that there is a good correlation between the residual water content and the clay fraction or silt fraction content in the grading, and the residual water content has a significant positive linear correlation with the clay fraction content, but a negative linear correlation with the silt fraction content. Residual matric suction has a nonlinear correlation with clay fraction or silt fraction content in gradation, which has a significant nonlinear negative correlation with clay fraction content and a positive nonlinear correlation with silt fraction content. The residual water content and the residual matric suction have obvious linear relationship with the content of montmorillonite but have no obvious correlation with the content of illite. The water-storage coefficient of unsaturated airfield foundation soil decreases exponentially with the increase of clay content and montmorillonite content.

Research on the Mechanical Properties of New Double-Row Pile Supporting Structure Based on an In Situ Study

According to the force characteristics of the double-row pile supporting structure, two new types of double-row piles are developed: the prestressed strong-constrained double-row piles and the recycling assembled double-row piles. A comparative field test was conducted on the support effects of the two new double-row piles and conventional double-row piles. The test site is located in a deep foundation pit of the Beijing Daxing International Airport Project. The feasibility and reliability of the two new support structures are verified. Field monitoring included section strain and bending moment of the pile body, horizontal displacement of the pile body, and vertical and horizontal displacement of the pile top. The research shows that because of the prestressed anchorage cables in the rear row piles, the prestressed strong-constrained support structure can provide better tensile performance from the rear piles, and the deformation and displacement are minimal. The recycling assembled double-row piles have similar deformation and displacement to the conventional piles. Through the connection of the steel members, the construction time can be effectively shortened. After the backfill of the foundation pit, the steel members can be recycled and the cost can be reduced.

Research on the Prediction Model of Shield Advancement Rate in Sandy Cobble Ground of Beijing

The long distance and tight construction period of the earth pressure balance shield tunneling in Beijing sandy cobble ground have a very positive impact on grasping the construction progress and improving the organization efficiency. Based on the real-time monitoring data of on-site earth pressure, cutter head speed, total thrust, screw conveyor speed, and cutter head torque, this study investigated the correlation between the shield advancement rate and the above parameters based on multiple nonlinear regression analysis method, which lay down the foundation of shield advancement rate prediction. The prediction model achieved satisfactory results and was further applied to an airport project. The results show that it is of guiding significance to use multiple regression method to establish shield prediction model and put forward the best advancement parameters to ensure the construction progress. The order in which the four operational parameters affect the advancement rate is total thrust, cutter head torque, screw conveyor speed, and cutter head speed. When the advancement time is greater than 57 min, the average advancement rate and daily progress are highly positively correlated. The research provides a reliable basis for the advancement rate prediction, safety control, and parameter optimization of shield advancement in similar ground.

Assessment of Challenges of Development Induced Displaced Households: In Case of Dambi Dollo University and Airport Project, Qellem Wollega Zone of Oromia Regional state, Ethiopia

Displacement of people may be due to various reasons development activity being one of them. This study is intended to assess challenges encountered by households displaced from Dambi Dollo University and Air Port Project site. The data was collected using questionnaire, interview, focus group discussion and document review. Descriptive method is used to analyze the data. The major findings are that compensation is in cash only and there is no resettlement as well as rehabilitation activity undertaken. Households faced challenges like homelessness, joblessness, social disintegration, difficulties of access to infrastructure and conflict among family members. Displacement worsened the life of vulnerable groups. The loss of farmland resulted in youth unemployment which in turn caused migration to urban where they are addicted to kchat, cigarette and alcohol. Proper Implementation of resettlement program, rehabilitation schemes, provisions of infrastructures and facilitating employment opportunity are recommended.

The traditional manual measurement method is inefficient and easy to be interfered by other factors, so it is difficult to meet the needs of large-scale, high-efficiency and high-precision measurement of airport construction. UAV photogrammetry improves the efficiency and accuracy of measurement, which can provide important reference for airport construction.

Forecasting air traffic demand for major infrastructure changes

The paper provides a review of traffic forecasting methods and compares the predictions generated by using different quantitative methods based on a case example from a planned Norwegian airport. The paper focuses particularly on two forecasting methods. The case airport exemplifies how analogies as a forecasting method might be better suited than elasticity methods for studies of major changes in infrastructure. The difference in traffic forecasts will depend on the methodological approach chosen and some generic considerations are given on this topic. In the studied case, we find that the airport project has a negative net present value when the lowest traffic forecasts are used and a positive net present value when the highest traffic forecasts are used. Hence, the inability to draw unambiguous conclusions would be confusing for decision-makers when deciding on whether to build the airport.

The Effect of Stakeholder-Associated Risks in Mega-Engineering Projects: A Case Study of a PPP Airport Project

Mega-engineering projects in the construction industry are generally carried out by public-private partnership models with the participation of different stakeholders. This paper aims to identify the effect of stakeholder-associated risks on the success of mega-engineering projects. Therefore, the risks were determined and then validated by focus discussions. Afterwards, an illustrative case study was presented to better understand the effects. Finally, a fuzzy analytical hierarchy process method was used to prioritize the identified risks. The prominent risks were found to include “improper partner selection,” “inadequate relationships with employer,” and “incompetent contractor selection.” Engineering managers need to work in close coordination with all members of the project. To better manage projects, engineering managers are expected to be familiar with the concepts of project risk management, because effective project risk management has a direct and positive effect on project management performance. Professionals in the field of engineering management can benefit greatly from the findings of this study by using it as a baseline for coordinating the relationships in multistakeholder organizational structures and analyzing stakeholder-associated risks throughout their projects.
