Explain the threats that exist towards the future water supply in the Himilaya’s.

Whilst water may be the core necessity of life and many people argue should be available for all, this is not the case, water is becoming a threatened commodity due to both physical and human impacts. As climate change looms and industrialisation increases flooded rivers, pollution and water scarcity will ensue. Not only will physical resources of water diminish but access to water in poverty stricken countries could create economic scarcity whereby the water supply is there it just cannot be attained due to a lack of money. The Himalayan countries such as China, Bangladesh, India and Pakistan are facing continues threats to their future water supply often as a result of each other.
The Ganges flows through India but ends in Pakistan, however along the way Indian companies have diverted large amounts of water into irrigation systems and dams have been placed so Bangladesh is deprived of its natural amount of water from the Ganges. This creates the threat of not just a lack of water in the future for Bangladesh but also a lack of food security as fishing cannot take place if water levels are too low and salinisation may occur, destroying habitats for marine life. Not only does India divert water from the Ganges it also pollutes by distributing waste from industries into the flow near Bangladesh. This creates an even large threat for Bangladesh as they will be at risk from undrinkable, contaminated water. Despite an agreement in 1990 to share the Ganges, India maintains power over its supply, leaving Bangladesh at the mercy of India.
In 1962 China and India fought over Aksai Chin and Arunachal Pradesh on their neighbouring borders due to territorial disputes but also water conflict as Aksai Chin holds one of the major sources of water for the Hotan county, the river Karakash. Forces clashed after China seized Aksai chin however despite many peace treaties signed there continues to be conflict. In 2012 China issued passport stamps with Aksai Chin and Arunachal Pradesh included leading to the Indian defence minister claiming China was its biggest threat when it comes to territory. If China maintains hold of these two areas India will face water shortages without access to Karakash and the Tarim River Basin, a future threat for both China and India is perhaps not their water sources but each other.
Many threats come in the form of human conflict in the Himalayas however there are physical threats such as climate change that can pose a risk. The Himalaya’s is home to the largest mountain in the world, snow topped Mount Everest and many others, as climate change warms the temperature there is a threat that snow cover may melt and as 70% of freshwater is kept in these snow covers, the surrounding Countries could lose or contaminate this water if it begins to melt and flood. The water could become contaminated as it flows through sewages meaning it is lost forever. Another physical threat is that of India’s monsoon period, the heavy rainfall can cause flooding and therefore sewage leakages again infecting the water supplies. The Himalayan threats are present from many angles suggesting it’s water security is incredibly in danger.
China has established a scheme to aid its water supply in the future called the South to North Transfer, aiming to join the rivers Yangtze, Yellow and Huai to channel water from the plentiful North to the in need South. However this has posed a new threat in trying to counteract another, the Yellow River is already at undrinkable levels of pollution due to industrial and domestic waste, if the rivers are channelled to combine this could worsen the water quality in the Yangtze River, therefore diminishing a further resource.

Water is increasingly under threat; human factors have a major role in not only creating these dangers but trying to prevent them. Various projects have been created in order to protect the Himalaya’s from these risks however as with China’s South to North transfer, these projects are sometimes threats in themselves.
