Mountains are home to one-fifth of the world’s population and the source of fresh water for half of all humanity. Mountainous regions are especially vulnerable to the impact of climate change. Switzerland is committed to the sustainable development of mountainous regions with an eye on climate change. To this end, the SDC works closely with Swiss and international partners.

The SDC's focus

As a mountainous country, Switzerland has a great deal of experience in harnessing the potential of its mountainous regions and in facing the challenges of sustainable (mountain) development. The SDC’s focus in this area is three-pronged:

  • Supporting initiatives and projects that promote sustainable mountain development with the aim of improving the living conditions of mountain communities and strengthening resilience against climate change.
  • Enhancing support for mountainous regions as vulnerable ecosystems that are essential to human needs and incorporating this support in global processes such as the 2030 Agenda for Sustainable Development.
  • Fostering knowledge generation, dialogue and sharing of information and experience between stakeholders at all levels.

In Nepal, for example, Switzerland has been helping better the living conditions of impoverished highland populations for over 50 years by supporting and improving infrastructure. Some 500 kilometres of roads and over 5,000 suspension bridges have been upgraded or built with Swiss support.

In Peru the SDC is engaged in a project to reduce the vulnerability of the Andean population to the impacts of climate change. The people here mainly subsist on small-scale agriculture, which is especially hard-hit by the effects of climate change. The SDC supports effective adaptation mechanisms to mitigate the negative impacts of climate change on the local population.

Through its global mountain programme, the SDC supports major regional mountain centres in different parts of the world, particularly the Andes, Africa, the Caucasus Mountains and the Hindu Kush Himalayan region. These regional knowledge centres contribute to the political dialogue on development of mountainous areas. Available knowledge is applied at these centres to develop concrete sustainable mountain development policies. At the same time, the SDC helps these centres to make this regional knowledge available to global networks so that other mountainous regions can benefit from it quickly and at little expense.

Background

Mountains are home to one-fifth of the world’s population and the source of fresh water for half of all people. Sustainable mountain development means making sensible use of mountain ecosystems for the present generation while preserving them for future generations.

Mountains were recognised as vulnerable ecosystems of global importance as early as the 1992 UN Conference on Environment and Development in Rio. The importance of mountains was reaffirmed at the UN Rio+20 conference in 2012. The protection of mountainous regions is also enshrined in the 2030 Agenda for Sustainable Development.

Mountain ecosystems are extremely diverse. They are also highly sensitive to climate change, natural disasters, industrial exploitation, migration (especially upland-lowland migration) and mass tourism. These phenomena often threaten entire mountain regions, putting the livelihoods of many people at risk. Most affected are highland populations that rely directly on local water, soil, flora and fauna. But people at lower elevations also benefit from healthy ecosystems in the mountains: for example, the water supply of roughly half of the world’s population depends on water resources from mountainous regions.

The retreat of glaciers due to climate change will exacerbate water scarcity in the medium and long term. The SDC sustains various scientific projects in the Andes, the Himalayas and in Central Asia studying glacier shrinkage and its consequences in key partner regions. Switzerland too is seriously affected by the retreat of glaciers and is therefore able to share where needed its experience in observing glaciers and their influence on water supply. By training glaciologists in partner countries it is spreading this knowledge and helping these countries to adapt to climate change. Switzerland has an important contribution to make to the scientific dialogue on climate change and is successful in putting forward its position in the international political dialogue.

Facts and figures

  • Mountainous regions make up 24% of the Earth's surface and are home to 12% of the world's population in 120 countries. 
  • 281 or a third of all UNESCO Cultural World Heritage Sites are situated entirely or partially in mountainous zones. These include the ruins of the 15th century Inca city, Machu Picchu. 
  • 15–20% of worldwide tourism takes place in mountainous regions, with an annual turnover of USD 70–90 billion.
  • Threatened ecosystems: Mountain ranges are a source of life for around a third of all plant species. Across the globe they are home to half of the most important zones for biodiversity. 
  • Diversity of species: Six of the 20 plant species that provide 80% of the world’s staple foods originate in mountainous regions. The potato was first domesticated in the Andes; some 200 local varieties are cultivated there. Thousands of varieties of quinoa are also produced there. The cultivation of maize began in the Sierra Madre ranges in Mexico and millet was first grown on the high plateau of Ethiopia. Farmers in the mountains of Nepal cultivate some 2,000 varieties of rice. 
  • The retreat of glaciers: In the Cordillera Blanca in the Peruvian Andes, 755 glaciers stretch across 528 km2. Since the first national glacier inventory was compiled in the 1970s, this area has shrunk by around 27%. 
  • Mountain cities: People in mountainous regions do not necessarily live in remote areas but also in large towns or capital cities. Kathmandu (Nepal) has some 3.4 million inhabitants, Quito (Ecuador) 2.7 million. La Paz (Bolivia) at 3,640 metres above sea level, with its population of circa 900,000, is the highest capital city in the world. 
  • Glacier shrinkage in Switzerland: Over the past 10 years, a fifth of Switzerland’s remaining glacial ice has disappeared. For the 1,500 or so Swiss glaciers, a total loss of some 1,400 million cubic metres of ice has been estimated for the hydrological year 2017/18. This means that the currently existing glacier volume declined by more than 2.5% in 2018.

Improving seed systems for smallholder farmers‘ food security

01.10.2017 - 30.09.2021

Smallholders often use informal seed systems to meet their seed needs. The project increases the access, availability and necessary diversity of adapted seeds to smallholders to reduce their vulnerability to shocks and contribute to their food and nutrition security. In national and global policy dialogues improved and pluralistic seed systems that better respond to the reality and the needs of smallholders are promoted and smallholders will get political recognition for their role in germplasm conservation.

Soutien au Dispositif National de Sécurité Alimentaire -PRESA-

01.05.2017 - 30.06.2022

Malgré l’excédent céréalier enregistré depuis plus de 20 ans, le Mali fait face à des crises alimentaires récurrentes qui touchent près du quart de la population. La Suisse soutient le Dispositif National de Sécurité Alimentaire par la combinaison des instruments de l’aide humanitaire et de développement en vue de gérer les crises alimentaires et renforcer la résilience des populations vulnérables. Cet appui contribuera à la stabilité du pays et de la sous-région et a le potentiel de réduire la migration forcée.



Air Pollution, Climate and Health (AiPoCH)

01.04.2017 - 31.12.2026

Air pollution is the largest single environmental health risk factor and closely related to climate change. Mitigating emissions can thus result in multiple benefits, but such interventions need to be rooted in a robust information and knowledge base. This project will strengthen high-quality climate/air pollution observation systems to increase awareness and evidence to ultimately trigger concrete action benefitting the health sector.


ASEAN-Swiss Partnership on Social Forestry & Climate Change (ASFCC) - Phase III

01.03.2017 - 31.08.2021

SDC’s intervention supports the implementation of the ambitious 2030 ASEAN framework strategy to address climate change and food security for the Southeast Asian region. It puts a special focus on the participation of local people and communities to safeguard, manage and benefit from forest goods and services – thereby making an important contribution to address poverty alleviation and climate change at local, national and regional levels.


Sustainable Livelihood and Disaster Mitigation (SLDM)

01.02.2017 - 31.12.2020

The intervention works on the nexus of DRR, food security and agroforestry and successor programme of the Sloping Land Management programme (SLM). Building on SLM, food security remains central, but DRR is the principle concern of the domain of intervention. Combining food security and DRR increases the scope to work holistically towards sustaining the resources on which livelihoods depend. The emphasis on sustainable food production addresses the humanitarian needs of communities. Coupling this with a focus on community action serves to enlarge the scope for groups and individuals to act more autonomously.
