China’s largest freshwater lake, Poyang Lake, typically covers more than 3,500 square kilometres and is a major water source for rice crops in Northwest China. But today, after a month of extreme drought, it’s only about a quarter of its size and has farmers digging for water.

The shrinking water levels can even be seen from space. An analysis of satellite imagery by Climate Home News, with the support from the monitoring platform Planet, shows significant impacts to freshwater ecosystems around the world.

As in China, several major rivers and lakes across Europe, Asia and North America have been severely affected by extreme weather, also hurting local populations. These impacts serve as a warning of future climate warming scenarios, experts said.

“What we have experienced this summer is what climate scientists tell us is going to happen in the future. This summer matches the predictions that we have for a hotter, drier future,” said Christine Colvin, advocacy director of the nonprofit The Rivers Trust.

Climate change is now becoming one of the “key drivers” of degrading freshwater ecosystems worldwide, according to the latest report by the UN’s panel of climate scientists. These ecosystems are fundamental for water access.

In China’s case, a month-long heatwave preceded the country’s worst drought in history. In a matter of weeks, some of the Asian country’s largest water bodies began to shrink, leading to economic and even cultural impacts.

Along the Yangtze river, for example, precipitation was 80% lower than usual,according to the World Meteorological Organization (WMO). This led to suppliers to Tesla, Toyota and Foxconn shutting down their factories due to lack of hydropower in the Three Gorges Dam.

“We are clearly witnessing the impacts of climate change,” said Wenjian Zhang, WMO assistant secretary-general.The situation in China is “complex”, he said, and has tested the country’s disaster prevention and relief work.

Although many of these water bodies —such as Lake Poyang— drop seasonally, this year’s drought was the worst in recorded history, Chinese officials said.

Attribution to climate change can be different depending on the region and can only be determined by conducting local studies, said Andrew Hoell, co-lead of the National Oceanic and Atmospheric Administration (NOAA) Drought Task Force.

However, Hoell added that “almost all regions of the globe have observed a trend to increasing temperatures that have led to more intense and longer duration heat events.”

In Europe, for example, the UK’s heatwave would have been almost impossible without current climate change, which has already warmed the planet by 1,2°C. After this event, drought was declared in large parts of the country.

Along the same lines, Europe’s Global Drought Observatory stated in its August report that low precipitation levels combined with “a sequence of heatwaves from May onwards”. As a result, water levels dropped in some major European rivers such as the Rhine in Germany, the Loire in France and the Tagus in Portugal.

In the Rhine, for example, some parts of the river were running at 45% of their average level for August, said Germany’s Federal Institute of Hydrology. Cargo ships were forced to carry lighter loads, increasing transport costs.

The impacts were even more significant because most of the continent’s wetlands were also depleted, said Colvin. This has left many freshwater ecosystems without their natural “buffer areas,” she added.

At a global level, wetlands have disappeared three times faster than forests since the 1970s, according to the Global Wetland Outlook report. To Colvin, this shows a need to “build back wetter.”

While developed nations focused more media attention, some developing countries also faced severe drought this year. In Iraq, for example, the Tigris and the Euphrates rivers have also been affected by heat and by new dams built in Turkey and Iran.

The Middle Eastern country has been suffering the effects of increasing heat for several years, with government reports even warning that the Tigris and the Euphrates rivers could go completely dry by 2040.

This year, water reservoirs along the Euphrates such as the Qadisiyah Lake showed significantly low water levels. In the Kurdistan region, the lowering levels of Lake Dukan threaten farmer’s harvest. In total, government officials have said water reserves are down 50% from last year.

One of the main problems of extreme drought in freshwater ecosystems are the impacts to biodiversity, explained Colvin. With lower water levels, pollutants become more concentrated, increasing their toxicity to wildlife. Combined with extreme temperatures, “anything living in those rivers is really struggling to survive,” she said.

In western United States, salmon species and other wildlife depending on them for food are on track to extinction, said Konrad Fisher director of the Water Climate Trust. The region’s water sources for humans are also shrinking.

“We have overallocated the water resources of most of the western United States. That makes us less climate resilient. We’re still in the 1800s of wasteful and excessive water use,” said Fischer.

Lake Powell, the second largest water reservoir in the US, is an example of the shrinking sources. Today, it’s levels are at a mere 26% of its capacity, its lowest levels since 1967. The Colorado river basin, of which it’s part of, provides water and hydroelectric power to 40 million people.

Rivers and lakes have been at the frontlines of this summer’s extreme weather, Colvin said. “We can take the health of rivers as a proxy for our readiness to climate change, and we’re not ready,” she concluded.

Addis Ababa riverside project gives priority to development over residents https://www.climatechangenews.com/2020/03/12/addis-ababa-riverside-project-gives-priority-development-residents/ Thu, 12 Mar 2020 06:00:13 +0000 https://www.climatechangenews.com/?p=41496 Ethiopia wants $900 million riverside project to be a model of green development - yet one resident says shelters were demolished 'without warning'

Go and ask any older person in Ethiopia’s capital city, Addis Ababa, and they will tell you the rivers were once very different.

“We were swimming in the rivers, played football and other games on buffers,” reminisced Takele Getachew, a 58-year-old man.

But for the past few decades that has not been possible, as the water became more and more polluted due to urban development.

“I witnessed closely how the Ginfile and Kebena have gradually been polluted and become waste disposal sites and sewerage spillways,” Getachew lamented.

After decades of neglect, there is now some hope for the waterways. Prime Minister Abiy Ahmed’s controversial Addis Ababa River Side Project, also known as the ‘Beautifying Sheger Project’, aims to clean up the rivers, making the city a model of green development in the process.

“I think the new riverside development project will save the rivers,” Getachew said, adding that they are a living memory of “past good times” and of the city’s “identity”.

The three-year project, expected to cost 29 billion birr ($900 million), aims to enhance the well-being of city dwellers by mitigating flooding and pollution through the creation of public spaces and parks, bicycle paths and walkways along the riverside.

But cleaning up Addis Ababa’s rivers comes with a human cost.

“The river was polluted and we were suffering floods during rainy season, but it is being cleaned now,’ said Asnakech Mesfin, 55, a mother of two who lives in an area known as the Sheraton expansion, an area affected by the development.

The project also runs through the densely populated villages known as Basha Wolde Chilot, Siga Mededa and Arogew Kera or generally Arat Killo.

The government “started demolishing our shelters without any warning’’, Asnakech said. “They send police here and demolished our shelters during holidays which led us to live on the streets for 4 months.’’

“The question is where shall we shelter? Any development should give priority for people first.”

The project starts from Mount Entoto to Akaki, covering 56km of green areas along the rivers, passing through the former Basha Wolde Chilot, in front of the national Parliament at Arat Kilo and the heavily populated Piassa in Addis Ababa’s centre.

The first phase of the project, running from Entoto to Bambis Bridge, is under construction with financial support the state-owned China Construction Company (CCCC), and is scheduled to be finished by May 2020. It is estimated to currently be about 55% complete.

It runs down to the Grand Menelik II Palace, through an area with villages like Asnakech’s. Now, there are just the place names remaining, but no residents.

Not far from the project site, there are mud and plastic homes where poor residents still dwell. The few people left along the river are experiencing tough conditions, with huge lorries passing through villages and construction taking place around them.

Thousands fear displacement during the second phase of the project.

The development has been criticised for not respecting two of the 15 principles of sustainable development, agreed in 2012 at the Stakeholder Forum of the Rio 20+ meeting.

Principle 9 states that, “all citizens should have access to information concerning the environment, as well as the opportunity to participate in decision-making processes.”

And principle 5 says developments should ensure “individuals and societies are empowered to achieve positive social and environmental outcomes”.

Neither of these principles appears to have been followed.

Most of Asnakech’s village was demolished long ago. The residents were relocated to the outskirts of the city, paying for new government accommodation through a loan scheme.

“They told us immediately to leave the place. We would be happy if they informed us before’’, she said.

“There is no value just constructing buildings and developing green areas without due attention to livelihoods,” she said. “They are treating us like enemies.”

“The government has not visited us and discussed with us to find a solution. I have been suffering to support my son who is a grade 6 student here on the street,” Asnakech said.

The city government and prime minister’s office declined to comment.

Addis isn’t the only one of Ethiopia’s cities to have faced critical waste management challenges and difficulties implementing and sustaining urban green infrastructure. But the problem is more complex in the capital.

Dr. Manaye Ewenetu, Associate Engineer at Symmetrys Structural and Civil Engineers, criticised the sustainability of the city’s green strategy but approved of the prime minister’s vision.

Ewenetu is concerned about two things – access to water and pollution. “There is already water stress in the city and will continue to get worse unless a proper demand and supply assessment is undertaken by the relevant authorities,” he said.

“As it is observed on the ground, most of the Addis Rivers are non-perennial rivers which mean they do not have flows for most of the year except during the winter period.’’

A detailed hydrological assessment should have been undertaken to establish the flow regime of the rivers in the city to ensure the flow of water in summer season, he said.

He also worries about pollution in the rivers. “At the moment dirty water from all residential and commercial properties including factories, schools, and hospitals is discharged into the rivers,’’ he said.

So while Addis Ababa’s River Side project is a genuine attempt to green a developing city, critics say it is still a long way from being a model of sustainable development.
