AS A HEATWAVE HEADS TO THE UK, and Indian cities battle with record temperatures, a new report from Christian Aid highlights how the climate crisis is increasing the severity of drought in ten of the world’s major cities, and demands an international fund to pay for climate caused loss and damage.
Despite covering more than 70 per cent of the earth’s surface, only three per cent of the world’s water is suitable for drinking. Of this fresh water, 70 per cent is locked in glaciers and ice caps. Less than 0.01 per cent of all fresh water worldwide is available for human use in lakes, rivers and reservoirs. Despite this, Christian Aid analysis shows global water use grew at more than twice the rate of population increases over the course of the 20th century.
Just last month, there was water rationing in the Chilean capital, Santiago and people have been queuing for water in New Delhi where temperatures have got so high that heatstroke is a risk even without doing any physical activity. In 2018, after extended drought, Cape Town came within days of becoming the first major city in the world to run out of water. ‘Day Zero’, when the taps for 4 million inhabitants would be turned off, was averted after emergency measures were implemented to cut the city’s water usage by 50 per cent.
In the UK, the CEO of the Environment Agency, James Bevan, warned that within 25 years London and the South East of England could run out of water. The cost of a severe drought to London’s economy is estimated by Thames Water to be £330 million per day, and would have severe economic, social and environmental consequences. The Environment Agency has said that by 2050 some rivers will see 50 to 80 per cent less water during the summer months.
The report, Scorched Earth: The impact of drought on 10 world cities, has been published alongside new polling by Savanta, commissioned by Christian Aid. The data reveals that given several options, a plurality of the UK public believe that rich countries should pay to mitigate the impact of drought (36 per cent). The data also reveals nearly six in 10 (57 per cent) people see the connection between their own actions and drought, but less than three in 10 (27 per cent) see the connection and are spurred into action.
With heatwaves hitting the UK in recent years, almost half (49 per cent) of adults across the UK are now concerned about the impact of drought on people in the UK. Despite this, over six in 10 (64 per cent) agree that they have never seen information about how to protect themselves from it.
The ten cities featured in the report are Sydney, Harare, Sao Paulo, Phoenix, Beijing, Kabul, New Delhi, Cape Town, Cairo and London. The danger of city droughts are only set to get worse without action to address climate change.
Without action to cut emissions and better management of freshwater resources, Christian Aid warns the toll will be felt acutely by the poor. According to the UN, lower-income city residents can pay up to 50 times more for a litre of water than their wealthier neighbours because they often have to buy from private vendors. Cities in poorer countries are also far more vulnerable than those in richer countries as they have fewer resources to adapt to the water shortages.
Report co-author, Christian Aid’s Nushrat Rahman Chowdhury, said: “Drought is not new but its intensity and frequency have increased over the last thirty years due to global warming. It is a real danger; it threatens lives and livelihoods of some of the poorest people in the world. These are communities which have done the least to cause the climate crisis. This is the reality known as loss and damage.
“To address this injustice, we not only need emissions cut but also provide financial support for those losses which cannot be adapted to. That is why, at this year’s UN climate talks in Egypt, we are calling for the creation of a loss and damage finance facility to be a major priority.”
Dr Friederike Otto, Senior Lecturer in Climate Science at the Grantham Institute, Imperial College London, carried out a study into the 2018 drought in Cape Town. She added: “Changing rainfall and higher temperatures – the result of greenhouse gas emissions – are making drought more common and more severe in parts of the world. As we saw in Cape Town, when it nearly reached Day Zero in 2018, this can add up to catastrophic water shortages even for some major cities.
“Our study of that event found climate change made the drought about three times more likely to occur. Until net greenhouse gas emissions are halted, the risk of drought threatening cities’ water supply will keep growing.”
Graham Knott, a retired water and environmental engineer, said: “Lack of a reliable supply of clean water, made worse by the impacts of climate change, is affecting cities in many different ways: we’re currently seeing terrible suffering in New Delhi due to droughts and heatwaves.
“Higher temperatures, combined with the growing levels of demand from cities make our precious freshwater resources extremely vulnerable. Even London and the southeast of England face water shortages in coming years if we don’t tackle climate change and adapt to its impacts by better managing our water resources and infrastructure.
“Set against this many cities have seen significant increases in damaging and fatal floods. Durban, South Africa, and even the desert cities of Saudi Arabia have recently suffered from significant flooding. Unchecked pollution of even the clean water we have makes things even worse. Without action and adaptation, climate change threatens to affect many things we currently take for granted.”
Mohamed Adow, Director of Nairobi-based climate and energy think tank, Power Shift Africa, said: “This is an important report which highlights the growing menace of urban drought. With more and more people living in cities, this is already becoming a major consequence of the climate crisis which will affect millions of people. Here in Africa we bear the brunt of this climate emergency, so we are acutely aware of the value and importance of water and what happens if we run out. This year’s COP27 climate talks will be taking place in Egypt, a country already facing the prospect of water shortages. It is vital that at these talks leaders come prepared with plans to cut emissions and provide the finance and support to help communities facing drought.”
The report also highlights the impact that drought is having in driving conflict, and in particular, in Crimea, the part of Ukraine annexed by Russia in 2014. The region is vulnerable to climate change and since the annexation, Ukraine protested by diverting the North-Crimea Channel which provides 85 per cent of Crimea’s water, sparking tensions in Russia and with prominent politicians like Konstantin Zatulin calling for a more aggressive foreign policy towards Ukraine.
“Research by the Pacific Institute has shown that conflicts over water, both within countries and between countries, are sharply increasing. In the 29 years between 1960-1989 there was 1.27 per year. But in the 27 years between 1990-2007 there was 4.61 per year.”
