Nepal continues to face challenges in promoting trade and commerce, linking isolated communities, and guaranteeing access to basic services like healthcare and education, even with concentrated efforts to improve transportation infrastructure. Roads and conventional aircraft are the main modes of transportation currently in use, and both are hindered by adverse weather and have trouble navigating the mountainous terrain. The challenging topography of Nepal’s hill and mountain regions marked by rugged landscapes, intense monsoon rainfall, unstable geological conditions, and steep slopes deviates transportation connectivity considerably (Pande, 2017).

The inadequacy of efficient road infrastructure alongside the scarcity of alternative routes amplifies the difficulties associated with transportation in Nepal, leading to increased expenditure on transportation. Rural communities bear the brunt of inadequate transportation infrastructure, facing barriers in accessing emergency aid, economic opportunities, and basic services. This disconnect exacerbates socioeconomic isolation, impedes trade and agricultural productivity, and perpetuates inequality. Pandey (2017) argues that enhancing rural infrastructure and transportation networks is crucial for poverty reduction, as it enhances economic opportunities, market access, and societal engagement in rural areas. Meanwhile, addressing existing transport and connectivity issues through innovative solutions is imperative to improve access to essential services, bolster economic sectors, and promote overall development.

This paper endeavors to delve into Nepal’s transportation challenges and evaluate the potential of Advanced Air Mobility (AAM), a recent innovation in air transport, as a viable solution. By transcending the limitations of traditional ground-based and costly air transportation infrastructure, AAM, which incorporates technologies like unmanned aerial vehicles (UAVs) and electric vertical takeoff and landing (eVTOL) aircraft, holds promise in enhancing the effectiveness, accessibility, and interconnectivity of Nepal’s transportation network.

By utilizing AAM technologies, Nepal can promote socioeconomic development and raise the living standards of its citizens. The objective of this study is to offer an understanding of the viability, consequences, and suggestions for putting AAM solutions into practice in Nepal, to address the nation’s transportation issues and clear the path for a more sustainable and accessible transportation system.

II. Nepal’s Transportation Infrastructure Status and Issues

More than 90% of goods and passenger movement in Nepal heavily relies on road transportation, while the country has the lowest road density in South Asia (Dhakal, 2022). The road network, totalling 77,025 km, constitutes a crucial lifeline, especially in rural areas, where the Provincial and local road network (PLRN) comprises 86% of the total road infrastructure. These roads, covering 31,965 km of provincial roads and 31,612 km of local roads, provide essential access to economic opportunities, healthcare, education, and relief efforts during natural disasters for nearly three-quarters of the rural population (World Bank, 2022). However, challenges persist, with only a quarter of PLRN roads offering year-round connectivity, maintenance neglect, and varied road standards posing additional hurdles.

The rugged terrain of Nepal poses substantial obstacles to both road construction and travel. Construction efforts in predominantly mountainous and hilly landscapes are arduous and time-consuming, making even paved roads risky to traverse due to winding and narrow sections, increasing the risk of accidents (Nate, 2022). These challenges significantly hinder access to services and markets, especially for farmers, limiting investment and production capabilities. According to studies conducted in rural Nepal, as travel times to markets increase, rural residents’ levels of education, income, cropping intensity, and access to non-farm employment gradually decline (World Bank, 2022).

Air services, on the other hand, have emerged as indispensable for navigating Nepal’s rugged landscapes, offering rapid transit options for valuable cargo and travellers, particularly in remote regions. Shah (2023) emphasizes the crucial role of air travel in Nepal’s tourism sector, supporting 381,000 jobs and contributing USD 807 million to the Gross Value Added (GVA). Despite the challenging terrain, air transport serves as a vital link, connecting remote areas and facilitating the movement of people and goods. Helicopter services play a vital role in Nepal’s tourism sector by granting access to remote destinations inaccessible by ground transport. Furthermore, they are crucial for addressing medical emergencies, including obstetric cases, in remote Nepal, aiding the healthcare sector significantly. According to the report of the Civil Aviation Authority of Nepal (CAAN) (2023), an increased trend has been seen in the passenger movement illustrated by Graph 1. The decline in 2019-2020 is perhaps because of the effect of COVID-19 which increased again after recovery. Insufficient and inefficient road infrastructure in Nepal has led to a growing demand for air transport, which offers advantages in terms of time and safety. Nevertheless, challenges such as high costs and limited availability impede the effectiveness of air transport in addressing transportation needs.

These seasonal factors exacerbate existing issues of inadequate road infrastructure, highlighting the need for comprehensive planning and investment to address transportation challenges year-round.

Nepal’s rugged terrain and vast river network create significant challenges for communication and transportation, particularly in hilly regions. The mountainous terrain in addition to more than 6000 rivers in Nepal makes building and maintaining roads and infrastructure more difficult. This leads to hazardous travel conditions, especially during the monsoon season, and limits accessibility in remote areas. Nepal’s Strategic Road Network (SRN), spanning over 12,000 km with 2,000 bridges, is crucial for transportation and trade. However, it suffers from significant deterioration, as indicated by Nepal’s low ranking (120th out of 141) in road infrastructure quality in the Global Competitiveness Report 2019. Approximately 18,861 meters of SRN roads need new bridges to improve connectivity and foster economic growth, exacerbating challenges, especially during the monsoon season (The ieConnect for Impact Program, World Bank). Moreover, poorly constructed road infrastructure in Nepal’s mountainous regions exacerbates erosion and landslide risks, disrupting local hydrological patterns and destabilizing slopes. This poses serious threats to communities’ lives and livelihoods (Sudmeier-Rieux et al, 2019).

Improving rural transportation infrastructure is crucial for enhancing living standards, as rural regions contribute significantly to the national economy. However, Nepal’s unique geographic, economic, administrative, and climatic conditions present significant obstacles to infrastructure development. Steep topography, frequent landslides, and competing development priorities hamper construction and maintenance efforts. Moreover, regulatory barriers and administrative hurdles impede investments in transportation infrastructure, while weather-related events like floods and earthquakes can cause extensive damage, necessitating costly restoration and maintenance efforts. Innovative and cost-effective solutions are needed to navigate these obstacles effectively. By embracing new and advanced approaches emerging in the field of transportation, Nepal can improve connectivity, promote economic growth, and ensure long-term resilience in its transportation sector, while minimizing environmental impacts.
