In Geophysics, topographic factors are observations that can be directly measured, but they are often ignored to simplify the model. Studying the coseismic deformation caused by earthquakes helps accurately determine the epicenter's parameterization. It provides a reference for the reasonable layout of coseismic observation stations and GNSS observation stations. After the Mw7.8 earthquake in Nepal in 2015, GCMT, USGS, GFZ, CPPT, and other institutions released their epicenter parameter. However, according to their parameters, the coseismic displacements simulated by the spectral-element method are quite different from the GNSS observations. Firstly, this paper inverts the geometric parameters of the seismogenic fault with Nepal's coseismic GNSS displacement. The spectral-element method determines the source's location and depth under the heterogeneous terrain and outputs the source parameters. Among the results of many studies, the surface source is more consistent with the generation mechanism of large earthquakes. Secondly, this paper calculates the fault slip distribution of this earthquake using SDM (Steepest Descent Method) based on GNSS and InSAR data, which is divided into 1500 subfaults, and the moment tensor of each subfault is calculated. This paper investigates the distribution characteristics of the coseismic deformation field of the 2015 Mw 7.8 earthquake in Nepal under three different models. The results show that the influence of topographic factors is ~ 20%, and the influence of heterogeneous factors is ~ 10%. This paper concludes that the influence of topographic factors is much more significant than that of heterogeneous factors, and the influence of both should be addressed in coseismic deformation calculations.

Nationalism remains a major influence on international relations in an increasingly globalised world. Many of the wars that erupted after the Cold War have their origins in ethnic tensions, border conflicts, or national aspirations. Given this, the geo-politicisation of nationalism deserves more attention in the literature. The current study aims to further the area by considering the role of territorial disputes in spawning various forms of nationalism and geopolitics. It develops an analytical framework based on the existing border dispute between Nepal and India in the 'Kalapani' region. Post-2019, the Kalapani dispute not only has represented bilateral border disputes between two entities but also reflects the overall geopolitics of the region. Similarly, it also represents the rise of 'nationalism' as a political anchor point in domestic politics in both India and Nepal. The paper based its assessment on the primary and secondary data analysis. Drawing on the data, this paper argues that border disputes between India and Nepal have two facets that signal the rising nationalism in both sides and the changing geopolitics of South Asia.

Ecosystem-based adaptation (EbA) is an ecologically sensitive, cost-effective, and locally adaptive climate adaptation strategy to strengthen the climate resilience of vulnerable communities. While many studies on EbA have been conducted in rural and mountainous regions or within the natural sciences realm, there is a lack of comprehensive research that assesses how urban EbA measures have been incorporated into existing policies and plans in Global South, including in Nepal. Ecosystem-based adaptation is in the early stages of its establishment as a fundamental component to address climate adaptation and sustainable development in urban environments. Accordingly, effective integration strategies, challenges, potential focal areas, and entry points have yet to be extensively studied. To address the literature gap, this paper analyses the types of EbA interventions and the extent of urban EbA integration within Nepal's climate, urban, and sectoral policies and plans. Direct content analysis and a qualitative scoring system were used to evaluate the plan components and assess the level of EbA integration. The findings indicate that the policies and plans recognise the importance of conserving, enhancing, and managing ecosystems for climate change adaptation, and EbA measures are mainly included in action-oriented sections. However, the results also reveal inadequate EbA integration, particularly in the information base, vision and objectives, and implementation aspects. The implementation component notably lacks comprehensive provisions for budget allocation, responsible authorities, definite timelines, and clear roadmaps. The breakdown of EbA integration in the policies and plans suggests that climate and urban plans substantially integrate urban EbA measures, but discrepancies exist with climate and urban policies and sectoral policies and plans. These findings collectively emphasise a pressing need to enhance the recognition and integration of urban EbA measures within policy frameworks with a view towards strengthening climate resilience and mitigating climate-related hazards in urban environments.

How does male out‐migration impact women's experience of post‐disaster reconstruction? This paper employs survey data collected by Nepal's Housing Recovery Reconstruction Platform in 2018 to establish robust associations between male out‐migration and three indicators of women's participation in rebuilding their private houses after the 2015 Gorkha earthquake: (i) knowing where to consult for information; (ii) visiting a local government official by oneself; and (iii) signing a rebuilding agreement with the local government. Twenty‐six semi‐structured interviews conducted in 2022 further revealed that women whose husbands were abroad undertook roles that they would not have performed had their spouse been present, including in relation to management and decision‐making. However, the interviews also highlighted challenges that women had to overcome, such as a lack of knowledge of procuring materials and difficulties leading the process as a woman. This study advances the literature by establishing a relationship between male out‐migration and variation in women's post‐earthquake rebuilding experiences. [ABSTRACT FROM AUTHOR]
