Why Affordable Housing and Seismic Resilience Must Drive the Next Phase of Himalayan Urban Growth

The ADB report warns that rapid urbanization across the Hindu Kush Himalaya is increasing housing shortages and disaster risks, calling for integrated policies that combine affordable housing, seismic resilience, climate adaptation, and urban planning. It urges governments, development partners, and private investors to strengthen risk-informed planning, housing finance, and resilient infrastructure to build safer, more inclusive, and economically sustainable mountain cities.

Rapid urbanization across the Hindu Kush Himalaya (HKH) region is creating new opportunities for economic growth, but it is also exposing millions of people to rising earthquake and climate risks, according to a new Asian Development Bank (ADB) working paper. Covering Bhutan, Nepal, and India's Himalayan region, the study argues that governments can no longer treat affordable housing, disaster resilience, and urban planning as separate priorities. Instead, it recommends integrating housing policies with climate adaptation, risk-informed land use, infrastructure development, and social protection to build safer and more productive cities. For policymakers, development partners, and investors, the report offers a practical roadmap to reduce disaster losses while supporting sustainable urban growth.

Housing Crisis Meets Seismic Risk

The HKH region stretches across eight countries and supports nearly 1.8 billion people through its major river systems. Yet it also lies along one of the world's most active tectonic fault lines. Between 1992 and 2022, disasters across the study area caused more than 71,691 deaths, affected around 1.2 billion people, left 8.4 million people homeless, and resulted in economic losses exceeding $110.9 billion. Although earthquakes accounted for only 6% of recorded disasters, they caused 61% of disaster-related injuries and 15% of fatalities, mainly because of unsafe housing.

Housing shortages are worsening the problem. Around 446 million people across the broader Himalayan region live in informal settlements or poor-quality housing. In Bhutan, many households, particularly women-headed families, spend over 42% of their income on rent. In India's Himalayan states, 56% of economically weaker households continue to face housing shortages. At the same time, Nepal estimated it needed 1.4 million urban housing units by 2023, but has consistently failed to meet annual construction targets. These shortages push families into unsafe settlements on unstable hillsides and flood-prone land, increasing both human and economic vulnerability.

Why Better Housing Is an Economic Investment

The report argues that affordable and earthquake-resistant housing should be viewed as economic infrastructure rather than simply a social welfare measure. Poor housing reduces labour productivity, increases healthcare costs, disrupts local businesses, and raises disaster recovery expenses for governments.

Importantly, the study finds that making homes earthquake resistant usually increases construction costs by only 5% to 20%, depending on building design and materials. Those additional costs can often be reduced through smarter designs, lower room heights, efficient layouts, and greater use of locally available materials such as reinforced rammed earth and engineered timber.

India's Pradhan Mantri Awas Yojana (PMAY-U) demonstrates how public support can improve both affordability and resilience. As of January 2026, the programme had sanctioned 12.22 million homes, with 9.6 million completed, making it one of the world's largest affordable housing initiatives. Bhutan's land pooling programme has also emerged as an effective way to expand serviced urban land while financing roads, water supply, and other essential infrastructure without large-scale displacement.

A Stronger Policy Agenda for Governments

The report recommends that governments move beyond isolated housing schemes and strengthen the entire housing value chain. This includes expanding serviced urban land, simplifying land registration, speeding up planning approvals, improving access to housing finance, strengthening building code enforcement, and investing in infrastructure before housing construction begins.

The study also calls for risk-informed urban planning based on seismic hazard maps, landslide assessments, liquefaction studies, and geotechnical investigations. New housing should be directed toward safer locations instead of allowing uncontrolled expansion into high-risk areas. Governments are encouraged to strengthen institutional coordination between housing, disaster management, finance, and urban development agencies so that resilience becomes part of everyday planning rather than a post-disaster response.

New Opportunities for Development Partners and Private Investors

For international development partners, the report highlights an opportunity to shift investments from disaster recovery toward prevention. Greater funding for hazard mapping, resilient infrastructure, affordable housing finance, institutional capacity building, and digital planning systems can significantly reduce future disaster costs while supporting climate adaptation goals.

Private-sector stakeholders also have an expanding role. Developers, financial institutions, insurers, engineering firms, construction companies, and technology providers can benefit from the growing demand for affordable housing, resilient construction materials, modular housing, digital risk assessment, and green infrastructure. ADB's $60 million investment in affordable housing finance through Aavas Financiers, expected to support around 110,000 women borrowers, demonstrates how blended finance can mobilize private capital while improving financial inclusion.

The report concludes that the future of Himalayan cities depends on integrating affordable housing, disaster resilience, climate adaptation, and sustainable urban planning into a single development strategy. Such an approach would not only save lives during future earthquakes but also improve economic productivity, attract investment, strengthen urban governance, and help governments build more inclusive and resilient cities capable of supporting long-term development.
