KOMIK, India (Thomson Reuters Foundation) - With a backdrop of the snow-capped Himalayas stretched out across a vibrant blue sky, it is hard to dispute the sign as you enter Komik that declares it to be the world's highest village with a road.
Others also boast the title - from Nepal's Dho Tarap to Bolivia's Santa Barbara. But at 4,587 meters (15,050 feet), this remote Buddhist hamlet near India's border with Tibet is no doubt among the planet's topmost motorable human settlements.
Yet despite its coveted status, life is harsh for the 130 residents of Komik, a quaint collection of whitewashed mud-and-stone houses located in the desolate Spiti Valley.
The region is a cold trans-Himalayan desert cut off from the rest of India for six months of the year when snowfall blocks mountain passes. Phone and internet connectivity is almost non-existent. Schools and clinics are a tough trek away.
But Spiti's some 12,000 inhabitants, who eke out a living farming green peas and barley, have a much bigger concern: their main sources of water - streams, rivers, ponds - are drying up.
"We are used to being in a remote place. We have our traditional ways of living," said farmer Nawang Phunchok, 32, as he sat tying bundles of a prickly desert bush together to insulate the local monastery's roof.
"But these days the water is not coming like it used to. The seasons are changing. We see there is less water than before."
There is little doubt India is facing a water crisis.
Decades of over-extraction of ground water, wasteful and inefficient irrigation practices, pollution of surface water like lakes and rivers, and erratic weather patterns attributed to climate change, have left many parts of the country thirsty.
But while government, charities and media increasingly focus on the drought-stricken farmers in the plains, their Himalayan counterparts - ironically living in a region often called the "Water Towers of Asia" - also need help, say conservationists.
From its deepest aquifers to its biggest rivers, India is one of the most water-challenged countries in the world, according to the World Resources Institute.
More than half of country - including the breadbasket northern states of Punjab and Haryana which produce 50 percent of the national government's rice supply and 85 percent of its wheat stocks - is considered highly water-stressed.
More than 50 percent of the country's wells have registered a decline in volumes in the last decade. Up to 80 percent of rivers, lakes, ponds and streams are polluted with human waste and sewage.
Over 63 million rural Indians - the equivalent of the population of Britain - do not have clean water to drink, cook or wash with, says WaterAid. Around 76 million need improved water sources and 770 million require proper toilets.
And climate change is exacerbating the situation.
Overall rainfall in the last century has been erratic, and the annual average temperature has risen by 0.5 degrees Celsius, says India's meteorological department.
"There exists a huge knowledge gap regarding the connection between water scarcity and climate change. There is an immediate need to fill this gap and make people aware about the importance of water conservation," said WaterAid India's Puneet Srivastava.
"The government also needs to undertake severe measures to regulate and monitor the use of groundwater resources."
The risks posed to food security and the plight of around 200 million farm workers are also a major concern.
Thousands of farmers have committed suicide over the last decade as unseasonal rains and drought combined with lower global commodity prices have hurt farm incomes.
India is forecast to overtake China as the most populous nation with 1.7 billion people by 2050. With rapid urbanization, rising demand for hydropower and changing weather patterns, the situation is set to worsen.
Government data forecasts India's annual water availability per person to drop by over 25 percent by 2050 to 1,140 cubic metres from 1,545 cubic metres in 2011.
Authorities have in recent years moved to better support farmers and boost water security in drought-prone areas.
Measures include providing insurance cover for crop failures and drought-resistant seeds to farmers, investments in irrigation, as well as a $3-billion project to clean up the Ganges, India's largest and most sacred river.
But environmentalists say the focus is largely on India's plains - where populations and farm outputs are higher - neglecting those living in the far-off, sparsely populated Himalayas.
Experts say the food, water and energy security of not just the people here - but over one billion others across Asia who depend on rivers such as the Yangtze, Ganges and Mekong, which are fed by Himalayan glaciers - is at stake.
Yet the Himalayas are one of the world's most sensitive hotspots to climate change. Melting glaciers, erratic rainfall, less snow and rising temperatures are taking their toll.
And Spiti Valley is clearly showing the signs.
"In 2015/16, there wasn't enough snowfall and so when summer came, the springs - which are the main source of irrigation for people - were all dried out. There was hardly any crop," said Ishita Khanna at Ecosphere, an eco-tourism company in Spiti Valley.
"With the climate changing, this could be disastrous for people living here if this keeps happening. There should be more support for people and a deeper understanding of their way of life here. It's a very hard life."
Tucked away in a corner of India's northern state of Himachal Pradesh, Spiti is only accessible during the summer, and even then via treacherous rugged roads carved along cliffs.
Translated as the "Middle Land" - referring to the land between India and Tibet - Spiti is dotted with stupas and centuries-old monasteries perched on crags.
Due to its remoteness, time appears to have stood here. Despite the building of roads which has brought in some tourism, the traditional way of life continues.
From April to September, locals farm tiny plots of land before winter sets in and temperatures drop to minus 30 degrees Celsius.
"We thought the road would bring us more prosperity in terms of tourism and trade, but it has been disappointing," said 55-year-old farmer Tenzin Andak from Komik.
"It is a worry for us. Life is getting more difficult these days, partly because there is less water," Andak said, as he took down some clothes hanging from a washing line outside home.
Spiti's water comes from snow – snowfall provides the moisture for farming and pastures for livestock rearing, while snow melt from glaciers feeds the streams and rivers which are the lifeline of these settlements.
And unlike in other parts of India where there are two farming seasons to plant and harvest crops, in Spiti there is only one - leaving farmers more vulnerable if one crop fails.
It has become warmer over the last few decades and there is less snowfall, say residents. The winters have become shorter and summers longer, they add.
Their main form of irrigation which are "kuls" - man-made channels running from glaciers to village ponds - are dry. As a result, sheep and goat herders have to trek higher to find grazing land and crops are much harder to cultivate.
A 2014 study by Jawaharlal Nehru University cited annual temperatures in the Indian Himalayas rose by up to 2 degrees Celsius over two decades, while the area of glaciers here have reduced by 13 percent over five decades.
"There is no doubt there is a big water crisis here," said Sub-Divisional Magistrate Arun Sharma, the senior-most government official in Spiti.
"We've put in place a lot of projects such as providing water tanks and constructing water catchment areas, but we are limited by the weather. For six months of the year, life stops as we are snowbound and we cannot do any major work."
