Northeast India stands at a crucial juncture where trade, climate, and connectivity play a role in shaping its future. As a gateway to Southeast Asia, it is essential for the trade and connectivity initiatives enacted via the Act East Policy. However, the region's vulnerability to climate change presents challenges to economic development and cross-border trade. Exploring the complex relationship between climate change and trade connectivity in this region is necessary to highlight concerns and opportunities that arise at this intersection.
Geopolitical Sensitivities: These arise from the region’s strategic location and complex socio-political landscape. India’s Northeast shares borders with China, Myanmar, Bhutan, Bangladesh, and Nepal, making it a crucial gateway for trade and connectivity with Southeast Asia. At the Rising North East Investors Summit 2025, Prime Minister (PM) Modi unveiled INR4.3 lakh crores in investments, positioning the region as a new economic axis. However, this transformation also places the region under heightened scrutiny from neighbouring countries such as China and Myanmar, especially amid unresolved border disputes and insurgency spillovers. The strained ties between India and the interim Bangladesh government have further disrupted the region’s trade, infrastructure schemes, and connectivity.

The presence of numerous ethnic groups and insurgent movements adds layers of complexity to the region's geopolitics. The colonial border demarcations have resulted in the division of ethnic communities across boundaries, leading to ongoing tensions and conflicts. The Indian government's efforts to integrate the region into the national mainstream further contribute to the geopolitical sensitivities.
Geographical Isolation: The ruggedness and remoteness have historically hindered the Northeast’s economic integration with the rest of the country. This geographical isolation is exemplified by states such as Arunachal Pradesh, where remote villages can only be accessed on foot or by helicopter. Expansion of the road network, such as the construction of new highways and the widening of existing roads, is necessary for better reach. For example, the ongoing construction of the Sela Tunnel in Arunachal Pradesh aims to provide all-weather connectivity to Tawang, which is challenging to reach during heavy snowfall.
Environmental Degradation: Arunachal Pradesh and Nagaland have witnessed significant deforestation, which has affected the region’s biodiversity and disrupted the habitats of numerous species. Illegal mining—as seen in Meghalaya—has resulted in increased soil erosion, water pollution, and the depletion of agricultural land. Water bodies are increasingly polluted from industrial waste, agricultural runoff, and domestic sewage. The Brahmaputra River faces pollution from various sources, which is threatening its aquatic life and human health. The hilly regions are susceptible to soil erosion, exacerbated by deforestation and unsustainable agricultural practices. Assam and Manipur experience soil loss during the monsoon season, reducing soil fertility and affecting agricultural productivity. The rich biodiversity is threatened by habitat destruction, poaching, and climate change. Urbanisation in cities such as Guwahati and Imphal has led to the destruction of green spaces, increased air and water pollution, and the generation of large amounts of waste.
Climate Vulnerabilities: The region’s high susceptibility to climate-related risks, including severe flooding during the monsoon, has led to widespread crop destruction and the displacement of communities. The increased frequency of floods, landslides, and droughts has disrupted transportation networks and damaged trade routes and infrastructure. Erratic monsoon patterns have affected agricultural productivity and impacted the export of cash crops. Rising temperatures and deforestation have threatened endemic species and have also affected eco-tourism and local economies. Furthermore, melting glaciers and erratic river flows have impacted the region’s hydropower generation capabilities.

Infrastructure Deficit: The region’s inadequate infrastructure, such as roads, bridges, and logistics facilities, has impeded the smooth movement of goods and people. While the development of multimodal transportation such as Bharatmala and Sagarmala projects, focusing on improving road, rail, and port connectivity to enhance regional trade and logistics, is promising, the Northeast still grapples with deep-rooted structural and administrative bottlenecks that require sustained, locally sensitive solutions. Flagship projects, including the India-Myanmar-Thailand Trilateral Highway, have seen slow progress, undermining regional integration goals. India’s Act East Policy, which aims to promote infrastructure development, market access, and economic integration, leading to Border Trade Agreements for trade flows and regional cooperation, are now being faced with security concerns, including insurgency and border tensions, which have historically deterred investment and disrupted project timelines.
Despite such challenges ranging from infrastructure deficits and difficult terrain to geopolitical sensitivities, Northeast India stands on the brink of transformation. Its rich natural resources, strategic location, and growing integration with national and international corridors present powerful opportunities for inclusive growth, regional trade, and sustainable development.

Enhancing Connectivity: Efforts to improve connectivity through the development of new roadways, railways, and air links hold the potential to integrate Northeast India more effectively with the national and global economy. The Kaladan Multi-Modal Transit Transport Project (KMMTTP) is a strategic initiative under India’s Act East Policy, integrating sea, river, and road transport to connect Kolkata port with Northeast India via Myanmar. The project includes a sea route to Sittwe port, a river route to Paletwa, and a road link to Mizoram, bypassing the Siliguri Corridor and potentially reducing transit times by up to four days. For example, the completion of the Bogibeel Bridge in Assam has significantly improved connectivity and facilitated faster movement of goods and people. Such infrastructural advancements can stimulate trade, tourism, and investment.
The ongoing construction of the Agartala-Akhaura railway link will connect Tripura with Bangladesh, enhancing cross-border trade. The Dhubri-Phulbari bridge is also under construction over the Brahmaputra River. This 19.3-kilometre bridge will be the longest river bridge in India, connecting Dhubri in Assam with Phulbari in Meghalaya to boost regional economic activities and serve as a major gateway for trade and development in the Northeast. A 167 km highway has been approved at INR22,864 crores, linking Meghalaya’s capital to Assam’s Barak Valley and enhancing access to Tripura, Mizoram, and Manipur. Additionally, a controlled-access highway between Mawlyngkhung (Meghalaya) and Panchgram (Assam) has been approved, reducing the travel time from Guwahati to Silchar from 12 to 5 hours. The improved internet and telecom infrastructure, implemented through BharatNet Phase II, will provide high-speed internet connectivity in rural and remote areas of the Northeast.
Roads, bridges, and railways must be designed to withstand extreme weather conditions, ensuring uninterrupted trade routes even during adverse climatic events.
Building Infrastructure Resilience: Trade routes, highways, and railways are vulnerable to landslides and floods. Developing climate-resilient infrastructure is of paramount importance. Roads, bridges, and railways must be designed to withstand extreme weather conditions, ensuring uninterrupted trade routes even during adverse climatic events. Climate change impacts transcend borders. Collaborative efforts with neighbouring countries can bolster climate resilience and trade. Joint initiatives in disaster management, sustainable development, and trade agreements can create a cohesive strategy to address shared challenges.
Investing in climate-resilient and sustainable infrastructure, such as hydropower for clean energy, boosts economic growth and long-term stability. The North East Gas Grid and Barauni–Guwahati Pipeline of 545 km was launched in April 2025 to supply cleaner energy. Conglomerates such as Adani and Reliance plan to invest INR 50,000 crores each in Assam and INR 5,000 crores for roads and hydro in the region. The Siang Upper Multipurpose Project (SUMP) holds immense potential as a cornerstone of sustainable development in Northeast India. With a projected capacity of 11,000 megawatts (MW), it stands to become one of the largest hydropower projects in the country, significantly advancing India’s renewable energy objectives. The commissioning of a 20 MW solar park in Mizoram’s Champhai district and a 25 MW green hydrogen plant in Assam bolsters the region’s renewable energy projects. Promoting eco-tourism creates alternative livelihoods. Strengthening trade ties with Southeast Asian neighbours can diversify trade portfolios and reduce dependency on climate-sensitive industries. Additionally, foreign direct investment can help improve this sector.
Sustainable Development: Investments in renewable energy projects, such as the small hydropower projects in Sikkim, and the promotion of eco-friendly tourism in Meghalaya, demonstrate how the region can drive economic growth while preserving its ecological balance, through increased investments in solar, wind, and hydroelectric power projects to reduce reliance on fossil fuels. The commissioning of small hydropower projects in Sikkim sustanaibly and judiciously harnesses the region's water resources. Tourism projects that prioritise environmental conservation and community involvement—such as homestays in Meghalaya—offer tourists an authentic and picturesque experience while supporting local economies. Other potential developmental opportunities for trade include the beverage industry (tea, coffee, and local wine), the bamboo Industry, handloom and weaving skills of the local community, handicraft industry, eco-tourism circuits, and an investment hub.
