Valuing The Precious Commodity of Water

FOR a long time we have enjoyed the luxury of a plentiful supply of water. So much so we have taken its availability for granted.

FOR a long time we have enjoyed the luxury of a plentiful supply of water. So much so we have taken its availability for granted.

How many of us are guilty of leaving the tap on while brushing our teeth, over filling the kettle or spending too much time in the shower?

Each person in the UK uses an estimated 150 litres of water a day which is equivalent to 264 pints of milk.

By the time water reaches our tap it has already been cleaned, treated and pumped from reservoirs, rivers and aquifers with much of it being leaked from pipes.

It is only in times of drought such as that experienced in parts of the UK are we forced to rethink how we value and use water.

Water is a crucial element for human existence as clearly demonstrated by the devastating effects of the severe drought in East Africa.

Safe water is necessary to avoid death from dehydration, reduce the risk of water-related disease and provide for domestic use.

It is estimated that each person needs about 20 litres of water each day to drink, cook and wash.

Everyone has a right to sufficient, safe, acceptable and affordable water. Unfortunately, these days fresh clean water is becoming a precious commodity.

A European Environment Agency report on water resources across Europe shows that southern Europe continues to experience the greatest water scarcity problems. However, water stress is growing in parts of northern Europe.

Drought is a feature of the UK’s variable climate, with dry spells possible at any time of the year. According to the Centre for Ecology and Hydrology (CEH), this year England suffered its driest spring in a century, leaving fields parched and many rivers at a record low.

This is in contrast to Scotland that had one of the wettest springs on record and areas of Lincolnshire, Cambridgeshire, parts of Bedfordshire, Northamptonshire, and western Norfolk which are in drought.

The dry weather affected navigation on the Leeds and Liverpool Canal with restrictions on boat movements. While recent rain and unsettled weather has helped the environment, farmers and water companies and eased canal navigation, this does not mean the drought or risk of drought is over. Damage to crops caused by the dry spring is now likely to be irreversible.

More dry weather will place further pressure on water resources. The Environment Agency believes this could result in drought conditions spreading into central England and further east.

This would impact livestock farmers, affecting the cost and availability of animal feed and bedding for next winter. while at the same time restricting arable farmers from spray irrigating their crops.

Public water supply can cope easily with a few months of dry weather, but prolonged droughts require careful management. The Yorkshire region experienced it worst drought in March 1995. Reservoirs in the upland Pennines hills were at capacity following a very wet period.

However, by the August, reservoirs in some areas were below 20 per cent capacity. This resulted in a severe water problem in the region and required emergency drinking water being tankered in from Kielder reservoir in Northumberland to West Yorkshire to help resolve the situation.

By 2020, the national demand for water in the UK could rise by as much as five per cent due to an increase in population and housing. This would mean finding an extra 800 million litres of water each day.

In particular, hot water used in the home is responsible for approximately 35 million tonnes of greenhouse gases a year due to reheating and water treatment processes.

Our abuse of water is due to the fact that majority of us do not have to pay for the amount we use. We do not provide electric sockets allowing people to use as much electricity as they want then why should we do it with water?

If we are to meet the UK national target to reduce our water use by 20 litres a day by 2020 then we will all have to become more “water wise”. Water metering is considered the fairest way to pay for water.

It also provides an incentive to use less water which is beneficial for the environment. A water meter is estimated to reduce household water consumption by about 10 per cent. However, this could result in the poorest households facing higher bills

We currently face the prospect of further water stress due to the combined effects of climate change, water intensive lifestyles and pressures of land use changes.

If we are to continue and enjoy high standards of water, we need to reduce demand, minimise the amount of water that we are extracting and increase the efficiency of its use.

This requires everyone doing their bit including water companies, farmers and consumers in addressing how we use and value water.

Stressing Over Water

FOR far too long rich Western countries have had the luxury of a plentiful supply of water. Yet water scarcity will be common as we experience greater water stress. This week delegates met at the World Water Forum in Istanbul to discuss what action can be taken to prevent global water scarcity. A combination of climate change, population growth, and increased demand for food, energy and biofuels will mean that by 2030 water scarcier than ever with almost half of the world’s population living in areas of water stress.

This week delegates met at the World Water Forum in Istanbul to discuss what action can be taken to prevent global water scarcity. A combination of climate change, population growth, and increased demand for food, energy and biofuels will mean that by 2030 water will be scarcer than ever before with almost half of the world’s population living in areas of high water stress.

When it comes to water we are most definitely leaving beyond our means. We may extract even greater amounts of water from the surface and groundwater sources. However, this is not a long-term solution.

Water is a crucial element for human existence. It is estimated that each person needs about 20 litres of water each day for the basics – to drink, cook and wash. Everyone has a right to sufficient, safe, acceptable and affordable water for personal and domestic uses. Safe water is necessary to avoid death from dehydration, reduce the risk of water-related disease and provide for cooking, personal and domestic uses.

Original Title: j1Unfortunately, these days fresh, clean water is becoming a precious commodity. Access to basic water-related services (e.g safe drinking water, sanitation and food production) remains inadequate in many developing countries. Especially in Sub-Saharan Africa where about 340 million people lack access to safe drinking water. It is often the poor who suffer the most. The number of people living on less than US$1.25 a day coincides with the number of those without access to safe drinking water.

Individuals and companies are all guilty of the wasteful consumption of water. The World Water Development report published this week warns some countries are already reaching the limits of their water resources. Climate change is likely to aggravate this situation even further leading to intense competition for water resources. The Intergovernmental Panel on Climate Change estimates that up to 2 billion people may be at risk from increasing water stress by the 2050s, and that this number could rise to 3.2 billion by the 2080s.

A European Environment Agency report on water resources across Europe shows that southern Europe continues to experience the greatest water scarcity problems. However, water stress is growing in parts of northern Europe. Climate change will further exacerbate water stress due an increase in the severity and frequency of droughts in the future, especially during the summer months.

If we are to avoid water stress than we need to cut demand, minimise the amount of water that we are extracting and increase the efficiency of its use. Good governance is essential for water management as water scarcity becomes an increasingly political issue. While policies exist to improve water management and to reduce water demand and loss these reforms have not had any noticeable effect. The World Water Development report calls for increased investment in water infrastructure by political and business leaders to avoid the risk of economic activity and development goals being undermined. It emphasises the importance of partnerships between governments the private sector and civil society.

The current global economic crisis could provide an opportunity to begin to address the emerging water crisis. However, the future management of water needs to be seen as an urgent and real issue to ensure that stakeholders can engage in addressing the issue.

As pictures are beamed back from Mars of droplets of water on Nasa’s Mars Phoenix Lander providing the first photographic evidence of water existing in its liquid state on the planet, we can only hope we can make the necessary changes to ensure we have more that a few droplets left on this planet.
