Evaluate the schemes being used to secure future water supplies?

As the worlds population reaches the 7 billion mark, the need to secure water supplies grows in equal measure. 1.4 billion people lack clean water already so projects to sustain water supplies are incredibly imperative in order to sustain life on earth. Many projects are tackling this issue such as Water aid in Mali and Clear Water in Australia however despite there being a multitude of projects their success could be debated.
The Himalayas have been experiencing water shortages due to various factors such as pollution in China’s Yangtze River and India’s swelling population. In Nepal, poverty plays a big part in providing water security, a non-governmental organisation called SWASTHA (strengthening water, air, sanitation and hygiene treasuring health) has been implemented by Practical Action. Using advancements in technology they aim to improve water quality, availability and provide sustainable methods of irrigation. A benefit of using technology such as solar powered water pumps to increase access to water is that it does not harm the local environment as it uses natural sun energy rather than large dams and allows a fairly quick fix. However it could be argued this is not appropriate technology for Nepal’s poorest as they will not be able to fund maintenance or replacement panels and must be dependent on the intermittent sun, instead of gaining control over their own water security they are dependent on Practical Action to provide these panels. Despite this flaw of one element of the project it must be remembered that SWASHTHA is also teaching effective irrigation techniques to farmers to enable them to not only control their use of water and protect them from wastage but also increase their food security as they can grow their own crops.
Across from Nepal, Pakistan is situated, facing increasingly worse water scarcity. The government has created the WAPDA (Water and Power Development Authority) scheme to store and replenish water supplies by investing in extensive dams. WAPDA was created in 1959 to undertake the task of planning schemes for irrigation and water development and has since built various dams including the Diamer-Bhasha on the River Indus. The dam does not only store 10km3 acres of water but generates 4,500 megawatts of electricity for Pakistan helping to aid development in industry. WAPDA plans to make the dam a tourist spot as well to further boost economic turnover however the cost of the construction will reach over $20million and take a further 12 years to complete. This scheme is a long term project and not a fast solution for Pakistans water security suggesting it’s benefits will not be reaped anytime soon. As well as the cost, the scheme has had to resettle thousands of residents whilst building work takes place, uprooting and disrupting livelihoods and homes. Despite the schemes overwhelming negative outcomes there are potential benefits such as the creation of 15,000 jobs and the ability to secure large quantities or water and store for devised and gradual use to sustain Pakistans water.

These are two examples of both bottom up and top down projects that aim to secure future water by acting now. The benefits of a bottom up such as Practical Action is it works with communities and educates safe and sustained water management to produce generations of people who will use their water effectively and have access to it. Bottom up projects are usually controversial as they tend to overlook residents as highlighted by WAPDA’s resettlements, however they have the power of money to secure large amounts of water. When it comes to water security there is no simple solution to protecting future supplies but as scarcity increases more schemes will have to take place perhaps leaving the door open for other issues such as conflict, strain and disruption as the water war continues.
