How climate change is affecting Kinnaur’s apples – and more

On April 16, Roshan Lal Negi woke up to find snow carpeting the courtyard of his home in Jangi village. Boys with smartphones quickly made videos to share on WhatsApp but more than a month later, the snow -- now filthy -- still sits on the lower parts of most peaks in Kinnaur district, Himachal Pradesh.

Particles from a dust storm in the northern plains might have travelled to Kinnaur and mixed with the unseasonal snowfall, suggests Manmohan Singh, Director of the meteorological centre in Shimla, giving the dusty appearance. The jury is still out, but most agree that this rain shadow region is experiencing a drastic shift in its weather patterns.

Rains are increasing, snowfall is declining, and temperatures are rising, which all have great impact on an area prone to landslides and fed by glacial melt.

"Nobody in cities is bothered about what's happening in Kinnaur. We are frequently facing such unusual weather events," Negi says.

Droughts and excess rainfall are more frequent and more intensely felt due to the shift in farming, from coarse grains to commercial plantations of apple and green peas.

Winter snowfall is also now more spread out. "The heavy snow in December and January has declined and there's increased activity in February and March," says S.S. Randhawa, Senior Scientific Officer at the State Council for Science, Technology and Environment.

The decadal average number of rainy days has increased by 43 per cent, from 77.4 days in 1980-90 to 111 days in 2000-2010, according to data from the National Initiative on Climate Resilient Agriculture.

The number of dry spells during the Kharif season, on the other hand, shrank to 10-15 days, while most dry spells between 1980 and 1990 lasted more than 20. This increased rainfall leads to a greater erosion of fertile topsoil, and infestations of pests that thrive in the humidity.

Kinnaur is famous for big and brightly-coloured apples, features caused by low night temperatures. Historically, the amount of crop lost to inclement weather has been low.

In April and May, while apple trees in neighbouring Shimla district and adjoining hills are adorned with white nets to protect against hailstorms, orchards in Kinnaur enjoy clear weather. But increasing rainfall and declining snowfall is pushing people out of this routine.

Cooler winter temperatures are important to induce dormancy, bud break and to ensure proper flowering in apples. But less snow, also reported in other parts of Himachal Pradesh, means that this crucial cool factor is not met, affecting apple quality and quantity.

Apple growers in Kinnaur's low- and mid-altitude hills felt that rising temperatures had affected production, but farmers at more than 3,000 metres reported no decline due to temperature, according to a 2013 study. Most growers also reported a shift in the apple harvesting period due to increasing temperatures. The infestation of pests and diseases -- including apple scab and canker -- are some climate change indicators that increase the cost of production.

Four years later, things are worse. This April, a month which typically sees the flowering and setting of fruits, has witnessed light showers almost daily. "Rains reduce the chances of pollination as bees are more likely to stay in their hives," says Rakesh Kumar, an entomologist at the Y.S. Pramar University of Horticulture and Forestry.

A traditionally dry region, the area does not have the means to deal with excess rainfall. Farms do not have proper drainage facilities as people never needed them. This causes waterlogging and diseases and insects which thrive on humidity.

Bhagat Singh Negi, a farmer in Rarang village, is worried that not even 30 per cent of apple trees will bear fruit. "New diseases crop up every year and even the chemicals we use are not as effective now. This year, many flowers dropped due to lack of pollination. It will be a difficult time for Kinnaur's economy," he says.

Extreme weather events are also catching people unaware. In 2015, the Pooh sub division received far less snow than usual, which dried the irrigation sources used to water apples. "We had to get water in tankers to save the trees. There was no harvest that year," says Gurmeet Negi, who owns an apple orchard.

The villages of Tabo and Sunam in upper Kinnaur saw incessant rain in June 2014, usually a dry month, which led to an infestation of ascochyta blight of the green pea crop. As a result, the market value of pea dropped drastically.

Farmers in Kinnaur take great pride in their low use of agrochemicals, but now most villages are seeing a rise in chemical use. "Up until eight years ago, we used to spray chemicals only twice in a year," says R.C. Negi of Thangi village. "Many would go without but now the frequency has gone up to seven sprays."

Other climate-indusced change has to do with residential structures. Concrete is fast replacing locally-sourced wood and stone as the preferred building material while traditional flat mud roofs are giving way to metal pent roofs.

"Increased rainfall in the historically-arid region erodes the flat mud roofs and wears away the mud-brick walls," says Tasha Kimmet, an art historian from University of Vienna, who studied the economic, climatic and cultural shifts in the region. She found that besides the improvement in economic conditions and increased accessibility to imported building materials, people are also adapting to changing weather patterns.

"Some residents, who are concerned about preserving their traditional building styles, are experimenting with tarps and waterproofing clays as part of the flat roof layering system, or building the roof at a subtle gradient," she says.

People in Kinnaur are used to living on the edge, but they have not yet to come to terms with sudden shifts in weather. And if this year's dusty snow is any indication, the situation may not improve anytime soon.
