Traditional crops and new innovations are offering Himalayan region a way to deal with the challenges of climate change, but there is much work to be done for this to become a truly viable alternative.

Over the past few decades, changes in climate change including higher temperature, lower rainfall, more extreme and unpredictable weather have made food production harder in Himalayan regions in India.

Making sure communities have the food they need is key. Not just in order to achieve the Sustainable Development Goals’ target of zero hunger, but to make sure the Himalayas can withstand the challenges created by climate change. This requires agricultural systems that sustain natural resources, biodiversity and traditional crop varieties that give options for adaptation.

A changing climate

In the central Himalayas, the drop in rainfall has aggravated forest degradation, leading to more crops being devastated by wild animals, especially wild boars. As a result, income from and interest in farming have declined and many young people are moving to urban areas for work. Although this is less pronounced in the more remote eastern Himalayan villages, issues including a rise in diseases, which is affecting cardamom and ginger crops, and prolonged dry periods have made life harder for communities.

Now a days, farmers in both regions are coming up with new – and old – ways to improve food security, climate resilience and incomes, while maintaining crop diversity. In the central Himalayas, this ranges from developing more intensive mixed cropping systems closer to homes to reduce their vulnerability to wild animals, to creating structures to harvest rainwater runoff to cope with water shortages.

Innovations of the old for the new

Farmers in the east have developed new cardamom cropping systems outside forests to avoid disease, and are changing when they plant and harvest paddy, millet and maize. They are dedicating more areas to perennial drought-tolerant crops such as broomstick grass and cardamom, which they are intercropping with food grains and vegetables. Broomstick grass, which was domesticated by farmers to reclaim degraded land after a major landslide in 1968, has become a key cash crop in the region.

In both regions, farmers have reintroduced or enhanced cultivation of resilient traditional crop varieties, such as millet and mustard. Communities have also started reviving dryland paddy, which is important for adapting to climate change. And farmers have developed new or improved crop varieties that have higher yields, and new bio-pesticides.

Trees are planted to provide fodder while reducing the pressure on forests. They have also increased cultivation of finger millet, which is highly nutritious and sought after in markets and requires less water than rice and wheat. A new composting method has been developed, which increases the soil’s fertility and moisture, and a new, effective bio-pesticide as well as many new methods of cultivation that have increased vegetable yields.

Half of the innovations are developed using a combination of traditional knowledge and techniques gained from scientists or NGOs. They include updating traditional communal farming practices and a new system for pooling transport to get farm produce to markets in the eastern Himalayas.

The SIFOR project worked with communities to develop Crop Protection Committees to prevent crop raiding, and new traditional food products to enhance revenues from traditional crops. Significantly, it revived agriculture in project villages and attracted interest from the new Uttarakhand Migration Commission.

The formalisation of innovations

As important as these developments are, it is equally crucial that the new and traditional crop varieties which these farmers have developed are formally registered. This is vital for protecting their intellectual property rights, including their rights to share in the benefits from their commercial use, and for encouraging further innovation and conserving local crop diversity.

Community seed banks have been established in both regions and are serving a critical need for farmers’ ability to access seeds and conserve threatened crop diversity. Many seeds that became extinct in certain areas have been brought in from other areas and are being revived, including dryland paddy, barley, corn, millet, lentils, spices and long-awned wheat, which has reduced animals raiding crops.

With the rise of extreme weather events, there is always the risk of crop failure. It is important that farmers exchange seed collections with formal institutions, such as the Indian Council of Agriculture Research’s local and regional research stations, while ensuring their intellectual property rights are respected.

Many traditional practices and technologies that have been revived or modified have proved to be pioneering and effective. But modernisation and cultural shifts are causing traditional knowledge and crop varieties to decline in both regions.

It is important that the scientific community recognises the crucial role that traditional farmers play and treats them as a peer group that has valuable local knowledge. Participatory action-research and plant breeding involving traditional farmers and scientists can generate new ideas and create links between ancestral and modern knowledge to confront climate change and other new challenges that mountains communities face.
