International Centre for Integrated Mountain Development (ICIMOD)

The International Centre for Integrated Mountain Development (ICIMOD) is a regional intergovernmental learning and knowledge-sharing centre serving the eight countries of the Hindu Kush Himalaya (HKH): Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal and Pakistan. It was established in 1983 under an agreement between the Government of Nepal and UNESCO, and is headquartered at Khumaltar in Lalitpur, within the Kathmandu valley. Its mandate covers mountain livelihoods, environmental conservation, water and cryosphere science, and regional cooperation on climate adaptation.^[1]

Bhutan is one of ICIMOD's eight founding regional member states. Since October 2020 the centre has been led by Pema Gyamtsho, a Bhutanese agricultural scientist and former Minister of Agriculture and Forests, who is the first citizen of an HKH country to serve as Director General since ICIMOD was founded.^[2]

Founding and legal status

The agreement providing ICIMOD's legal basis was signed between the Government of Nepal and UNESCO in Paris in 1981. Nepal offered to host the centre, and UNESCO, together with the Governments of Switzerland and the Federal Republic of Germany, acted as founding sponsors. ICIMOD was inaugurated on 5 December 1983 and given domestic legal personality by an Act of Parliament in Nepal the same year. Over the following decade the centre evolved from a UNESCO-affiliated regional body into an autonomous intergovernmental organisation, with its eight regional member countries acceding to its statute.^[1]^[3]

Article 1 of the statute designates Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal and Pakistan as Regional Member Countries. Together these states cover the entire arc of the Hindu Kush, Karakoram and Himalayan ranges, a region of roughly 4.2 million square kilometres inhabited by about 240 million people and supplying water and ecosystem services to nearly 1.9 billion people in the ten downstream river basins, including the Indus, Ganges, Brahmaputra, Mekong, Yangtze and Yellow Rivers.^[4]

Governance

ICIMOD is governed by a Board of Governors made up of one representative from each of the eight regional member countries together with independent members. The Board sets strategy, approves the work programme, and appoints the Director General. Bhutan's seat on the Board has historically been filled by a senior official of the Ministry of Agriculture and Forests or the National Environment Commission.^[1]

The Director General is the centre's chief executive. For the first 37 years of ICIMOD's existence, every head came from Europe or the United States: the founding Director, Kenneth Colin Rosser of the United Kingdom, served from 1984 to 1989, followed by E.F. Tacke of Germany (1989–1994), Egbert Pelinck of the Netherlands (1994–2000), Gabriel Campbell of the United States (2000–2007), Andreas Schild of Switzerland (2007–2011), and David Molden of the United States (2011–2020). The appointment of Pema Gyamtsho in 2020 marked the first time a national of a regional member country had led the centre.^[5]

Programmes and knowledge work

ICIMOD organises its work around cryosphere and water, climate and environmental risks, biodiversity and ecosystem services, livelihoods and migration, and regional cooperation. Its cryosphere programme is the best known internationally: the centre operates one of the largest glacier-monitoring networks in the Himalayas and has been a principal source of peer-reviewed data on Himalayan ice loss, snow persistence, permafrost, and glacial lake expansion. It also runs the regional air pollution and brown cloud work, the Kailash and Kangchenjunga transboundary landscape initiatives, and programmes on mountain agriculture, tourism, rangelands and gender.

The centre's flagship publication is the Hindu Kush Himalaya Assessment: Mountains, Climate Change, Sustainability and People, released in 2019 after more than five years of work by over 350 scientists. Spread across sixteen chapters, it is widely described as the region's equivalent of an IPCC assessment report and concluded that even if global warming is held to the Paris Agreement goal of 1.5 °C, roughly one-third of HKH glacier volume would still be lost by 2100. Under higher-emissions scenarios, losses rise to around two-thirds of glacier volume.^[6]

In 2023 ICIMOD published the follow-up assessment Water, Ice, Society, and Ecosystems in the Hindu Kush Himalaya (HI-WISE), which projected that Himalayan glaciers could lose up to 80 per cent of their volume by 2100 under a high-emissions pathway. In March 2025 the centre reported a 23-year record low in seasonal snow persistence across the HKH for the third consecutive year, warning of downstream water shortages for millions of people. In March 2026, on World Day for Glaciers, ICIMOD released two further reports — Changing Dynamics of Glaciers in the Hindu Kush Himalaya Region from 1990 to 2020 and the HKH Glacier Outlook 2026 — which documented that ice-loss rates across the region's glaciers have roughly doubled since 2000 and that glaciers below 0.5 km² are disappearing fastest. Between 1990 and 2020 the region's glaciers lost about 12 per cent of their total area.^[7]^[8]

Bhutan and ICIMOD

Bhutan joined ICIMOD as one of its original regional member states and has remained continuously engaged since. The practical relationship is unusually close for three reasons: Bhutan's small scientific workforce benefits from access to regional training and datasets; more than 70 per cent of Bhutan's land area is classified as mountainous, making almost every ICIMOD programme relevant to national policy; and Bhutan's exposure to glacial lake outburst floods (GLOFs) places it at the sharp end of Himalayan climate risk.

Glaciers and glacial lake outburst floods

In 2001 ICIMOD worked with Bhutan's Department of Geology and Mines to produce the country's first inventory of glaciers, glacial lakes and GLOFs. The inventory classified 25 of Bhutan's glacial lakes as potentially dangerous, with Thorthormi Tsho in the upper Pho Chhu basin identified as the single most hazardous. ICIMOD subsequently provided hazard mapping, remote-sensing analysis and technical advice for the Royal Government of Bhutan's Thorthormi lake-lowering project, implemented between 2008 and 2012 with funding from the Global Environment Facility, UNDP and the Austrian Coordination Bureau. Because heavy machinery would have destabilised the moraine dam, workers excavated drainage channels manually, lowering the lake level incrementally. The work was part of the wider response to the 1994 Luggye Tsho GLOF, which had damaged Punakha Dzong and killed more than twenty people downstream.^[9]^[10]

ICIMOD has continued to support field surveys of Bhutan's high-altitude lakes and contributes to the National Center for Hydrology and Meteorology's periodic reassessment of potentially dangerous glacial lakes. Bhutanese glaciologists and hydrologists routinely attend ICIMOD training programmes in Kathmandu, and much of Bhutan's published cryosphere data is co-authored with ICIMOD researchers.

Agriculture, rangelands and livelihoods

Before his political career, Pema Gyamtsho himself worked at ICIMOD from 2002 to 2006 as a rangeland and policy specialist, having completed a PhD at ETH Zürich on Himalayan pastoral systems. The centre's long-running work on yak herding, high-altitude rangelands, organic agriculture and transboundary landscape conservation has shaped research agendas at Bhutan's Council for RNR Research and at the Ministry of Agriculture and Forests. Bhutanese policy in areas including cordyceps harvesting rules, community forestry and climate-smart agriculture draws on comparative studies produced with ICIMOD participation.

Climate diplomacy

ICIMOD has given Bhutan a multilateral platform for mountain climate advocacy that the country could not sustain alone. The Hindu Kush Himalaya Call to Action, adopted by the eight member states in 2020 during the first ministerial declaration on mountain climate change, has been cited by Bhutanese delegations at successive UNFCCC conferences. Under Gyamtsho the centre has argued that the HKH receives disproportionately little climate finance relative to the scale of its exposure, a line that aligns with Bhutan's own position as a carbon-negative least developed country seeking mountain-specific adaptation funding.

Funding and partners

ICIMOD is financed through core contributions from its regional member countries, core funding from non-regional partners, and programme and project funding from bilateral and multilateral donors. Major contributors over the years have included the Swiss Agency for Development and Cooperation (SDC), the Norwegian Agency for Development Cooperation (Norad), the Swedish International Development Cooperation Agency (Sida), the Austrian Development Agency, the German federal ministries BMZ and BMU, the UK Foreign, Commonwealth and Development Office (formerly DFID), the European Union, the International Development Research Centre (IDRC) of Canada, IFAD, the Norwegian Ministry of Foreign Affairs and USAID. The centre also collaborates with the World Meteorological Organization, UNEP, FAO, IUCN, the World Bank and the Asian Development Bank, and its scientists contribute to IPCC working group assessments.^[11]

Critiques and challenges

ICIMOD operates in a politically complicated neighbourhood. Its eight member states include pairs with long-standing bilateral tensions — India and China, India and Pakistan, and Afghanistan and several of its neighbours — and producing regional science that all governments find acceptable requires careful framing. The centre's operational reach into Afghanistan has been sharply reduced since 2021 following the change of government in Kabul.

The centre's heavy reliance on bilateral donor funding has also drawn attention to its financial vulnerability. A pause in US development assistance in 2025 affected a number of ICIMOD programmes, and Gyamtsho has publicly discussed the need for more predictable multilateral climate finance for mountain regions. Academic observers have noted a further structural tension: as a consensus-based intergovernmental body, ICIMOD must balance scientific directness on issues such as cryosphere loss and transboundary air pollution against the diplomatic preferences of member states, some of which are among the world's largest emitters.
