In its new special report on climate change and land, the IPCC calls for more effective and sustainable land management, and more sustainable food consumption. But who is the onus on to go vegetarian, or look after land better? You, me, the “global elite”? The world’s poorest people, or perhaps the many millions of newly-wealthy Chinese or Indians? Or maybe our governments?
The answer depends on how you interpret the report, which can be read in two ways. On one hand, it is a moral call for individual consumers and food suppliers to become more sustainable. On the other, it is a call for governments to promote sustainable food consumption and production choices.
This is not an either/or situation – the report should be read in both ways but with recommendations for different population groups. To wit, whether someone is individually responsible for taking on board the IPCC’s recommendations depends on the extent to which they are subject to one or more of three forms of inequality.
1. Not everyone can afford to eat veggie or local
First and foremost, massive global wealth inequality affects the extent to which individuals and communities are able (or, rather, should be expected) to implement the recommendations of the IPCC report. It’s a lot easier to go vegetarian when you have the money to eat what you like. In the Global South, many have not benefited from industrialisation, while remaining in even more need of implementing measures to counter climate risks. Even in the more affluent countries of the Global North, many people live in abject poverty and have to make tough choices as how to spend their limited resources.
This highlights the need to make sustainable food accessible and not just available. The authors of the IPCC report acknowledge as much, emphasising how rising costs may lead to undernourishment as people turn to cheaper replacements, such as fast food. This is why sustainable food must be promoted alongside poverty alleviation. In the Global South, green growth must be priority as long as it includes local stakeholders, who are often experts on sustainable land management.
2. Some people emit more than others
Carbon footprint is highly correlated with inequality. As a 2015-report by Oxfam showed, the top 10% of income-earners, mainly living in affluent countries, are responsible for almost half of global greenhouse gas emissions, while the bottom half are only responsible for 10%. Even within affluent countries, there is a big divide between rich and poor. In other words global warming is not driven equally by everyone, but rather is highly correlated with income.
Of course, this does not mean that we should encourage unsustainable living in less developed countries. Rather, we should recognise that the consumption and production patterns of the world’s worst-off are not necessarily unsustainable. Although the world’s high and upper-middle income countries are home to about half the population, they are responsible for 86% of emissions. In comparison, Africa is home to 16% of the world’s population, yet only emits 4% of the global total. Meanwhile the very poorest countries – 9% of the global population, or 700 million people – emit just 0.5%. (Tellingly, the average per capita emissions of North Americans is more than 17 times that of the average African.)
Consequently, it would be possible to add several billion people in low-income countries, where population growth is already the highest, without massively changing global emissions, while adding just one billion individuals in high-income countries would increase global emissions by one-third. As the income of less-affluent populations grows, however, it does become necessary to encourage more sustainable practices.
3. People are not equally vulnerable
But less-affluent people in the Global North aren’t entirely off the hook. While inequality of income and carbon footprint does mean they are absolved of some responsibility to act more sustainably, this group still benefits from better infrastructure and more equitable institutions which should shelter them from the worst impacts of climate change. Conversely, inhabitants of low and middle-income countries, especially those in fragile environments like rainforests, mountains or coastal regions, are particularly vulnerable.
So while taking action to mitigate climate change is necessary, we cannot lose sight of the fact that many communities require financial and institutional support to adapt to existing changes to their local environment as well as to build resilience to near-certain climate risks in the future. While most people in the Western world are still only beginning to see and feel the effects of climate change, they must continue to commit resources to those most vulnerable and worse-off communities, who are often invisible to them.
In sum, whether someone can be held individually responsible for taking on board the IPCC’s recommendations crucially depends on whether they are able to do so without risking their life, livelihood, or well-being. Because inequalities in income, emissions, and vulnerability to climate change are still widespread, the report must first and foremost be read as a call for governments to make sustainable consumption and production options accessible. Addressing climate change and food security must go hand in hand with addressing global and local socioeconomic inequalities.
The word “climate” makes most of us look up to the sky – however, the IPCC’s new special report on climate change and land should make us all look under our feet. This is how Anna Krzywoszynska, Research Fellow and Associate Director of the Institute for Sustainable Food, University of Sheffield introduced her article published on The Conversation of last week before adding that ‘Land, the report shows, is intimately linked to the climate. Changes in land use result in changes to the climate and vice versa. In other words, what we do to our soils, we do to our climate – and ourselves.’ So, keeping Global Warming to well below 2°C is the hurdle that all humans need to get over in order to achieve the Paris Agreement requirements.
Land is already under growing human pressure and climate change is adding to these pressures. At the same time, keeping global warming to well below 2C can be achieved only by reducing greenhouse gas emissions from all sectors including land and food, the Intergovernmental Panel on Climate Change (IPCC) said in its latest report.
“Governments challenged the IPCC to take the first ever comprehensive look at the whole land-climate system. We did this through many contributions from experts and governments worldwide. This is the first time in IPCC report history that a majority of authors – 53 per cent – are from developing countries,” said Hoesung Lee, chair of the IPCC.
This report shows that better land management can contribute to tackling climate change, but is not the only solution. Reducing greenhouse gas emissions from all sectors is essential if global warming is to be kept to well below 2C, if not 1.5C.
In 2015, governments backed the Paris Agreement goal of strengthening the global response to climate change by holding the increase in the global average temperature to well below 2C above pre-industrial levels and to pursue efforts to limit the increase to 1.5C.
Land must remain productive to maintain food security as the population increases and the negative impacts of climate change on vegetation increase. This means there are limits to the contribution of land to addressing climate change, for instance through the cultivation of energy crops and afforestation. It also takes time for trees and soils to store carbon effectively.
Bioenergy needs to be carefully managed to avoid risks to food security, biodiversity and land degradation. Desirable outcomes will depend on locally appropriate policies and governance systems.
Climate Change and Land finds that the world is best placed to tackle climate change when there is an overall focus on sustainability. “Land plays an important role in the climate system,” said Jim Skea, Co-Chair of IPCC Working Group III.
“Agriculture, forestry and other types of land use account for 23 per cent of human greenhouse gas emissions. At the same time natural land processes absorb carbon dioxide equivalent to almost a third of carbon dioxide emissions from fossil fuels and industry,” he said.
The report shows how managing land resources sustainably can help address climate change, said Hans-Otto Pörtner, co-chair of IPCC Working Group II.
“Land already in use could feed the world in a changing climate and provide biomass for renewable energy, but early, far-reaching action across several areas is required. Also for the conservation and restoration of ecosystems and biodiversity,” he added.
Desertification and land degradation
When land is degraded, it becomes less productive, restricting what can be grown and reducing the soil’s ability to absorb carbon. This exacerbates climate change, while climate change, in turn, exacerbates land degradation in many different ways.
“The choices we make about sustainable land management can help reduce and in some cases reverse these adverse impacts,” said Kiyoto Tanabe, co-chair of the Task Force on National Greenhouse Gas Inventories.
“In a future with more intensive rainfall the risk of soil erosion on croplands increases, and sustainable land management is a way to protect communities from the detrimental impacts of this soil erosion and landslides. However there are limits to what can be done, so in other cases degradation might be irreversible,” he said.
Roughly 500 million people live in areas that experience desertification. Drylands and areas that experience desertification are also more vulnerable to climate change and extreme events including drought, heatwaves, and dust storms, with an increasing global population providing further pressure.
The report sets out options to tackle land degradation and prevent or adapt to further climate change. It also examines potential impacts from different levels of global warming. “New knowledge shows an increase in risks from dryland water scarcity, fire damage, permafrost degradation and food system instability, even for global warming of around 1.5C,” said Valérie Masson-Delmotte, co-chair of IPCC Working Group I.
“Very high risks related to permafrost degradation and food system instability are identified at 2°C of global warming,” she said.
The MENA region according to a UNICEF report, without improved education and meaningful work opportunities will have to face the critical risk of an unprecedented increase of 5 million out-of-school children, and over a 10 per cent rise in youth unemployment by 2030. Xinhua came up with the following article edited by Mu Xuequan.
UNITED NATIONS, Aug. 8 (Xinhua) — Without improved education and meaningful work opportunities in the Middle East and North Africa (MENA), the region faces a critical risk of an unprecedented increase of 5 million out-of-school children by 2030, according to a United Nations Children’s Fund (UNICEF) report: MENA Generation 2030, which was published Thursday.
MENA Generation 2030 is the first report to make a direct link between investment in children, economic growth and social development.
The report warns that over a 10 per cent rise in youth unemployment by 2030 is expected, if the situation remains unchanged.
According to the report, the region has the highest youth unemployment rates in the world; nearly 15 million children are out of school due to a combination of poverty, discrimination, poor quality learning, violence in schools and armed conflict.
“We are at a serious risk of not meeting the Sustainable Development Goals in the MENA region with devastating consequences on children and young people,” said Geert Cappelaere, UNICEF Regional Director for the Middle East and North Africa.
“The only way out is through the implementation and budgeting of policies for children, ending violence and armed conflict, having a politically and socially stable environment, and promoting gender equality,” Cappelaere added.
The report urges governments to increase financing for early childhood development, improve basic education and simultaneously nurture the skills needed to match the rapidly changing economy.
Egypt Today.com posted an article dated August 7, 2019, that brings to light an unusual construction project concept. It combines building towers with an agricultural development project. The project concept if multiplied in numbers will certainly be increasing Egypt’s limited area of farm land that is confined to the Nile Valley and Delta, with a few oases and some arable land in the Sinai peninsula.
CAIRO – 7 August 2019: Italian Architect Stefano Boeri spoke to CNN about Africa’s first vertical forests that will be built in Egypt’s New Administrative Capital (NAC), which is still under construction and is 30 miles east of Cairo.
Each of the three cube-shaped blocks will be 30 meters high and will house seven floors, 350 trees, and 14,000 shrubs of over 100 species. “Each tower of trees aims to provide its human residents with an average of two trees, eight shrubs and 40 bushes each,” as reported by CNN.
Boeri has been designing the blocks in collaboration with Egyptian designer Shimaa Shalash and Italian landscape architect Laura Gatti. Shalash told CNN that execution of the project is set to start in 2020 and finish in 2 years. One of the three buildings will be an energy self-sufficient hotel, while the other two will contain residential apartments.
“Each apartment will have its own balcony with a range of plant species suited to the local climate, planted at various heights and to bloom at different times to provide a lush appearance year round. Plants at every level will provide natural shading and improve the surrounding air quality by absorbing an estimated 7 tons of carbon dioxide and producing 8 tons of oxygen per year,” CNN reported.
Shalash and colleagues explained to CNN that the project – owned by a private real estate developer – is part of a bigger plan to introduce “thousands of green flat roofs and a system of “green corridors” in the city.”
The Rockfeller Foundation supported Cities‘ Ruth Michaelson wrote from Riyadh, Saudi Arabia on Tue 6 Aug 2019 the following article that elaborates on water increasing scarcity in Saudi Arabia and how despite that, life carries on somehow unaffected.
As Riyadh continues to build skyscrapers at a dizzying rate, an invisible emergency threatens the desert kingdom’s existence
Bottles of water twirl on the conveyor belts of the Berain water factory in Riyadh, as a puddle of water collects on the concrete floor. In a second warehouse, tanks emit a low hum as water brought in from precious underground aquifers passes through a six-stage purification process before bottling.
“In Saudi Arabia, there are only two sources of water: the sea and deep wells,” says Ahmed Safar Al Asmari, who manages one of Berain’s two factories in Riyadh. “We’re in the central region, so there are only deep wells here.”
Most water withdrawn comes from fossil deep aquifers and predictions suggest these may not last more than 25 years: UN
Perhaps not surprising for someone who makes a living selling water, Asmari professes to be untroubled about the future of Saudi Arabia’s water supply. “Studies show water in some reserves can stand consumption for another 150 years,” he says. “In Saudi Arabia, we have many reserves – we have no problems in this area.”
His confident predictions are out of sync with the facts. One Saudi groundwater expert at King Faisal University predicted in 2016 that the kingdom only had another 13 years’ worth of groundwater reserves left.
“Groundwater resources of Saudi Arabia are being depleted at a very fast rate,” declared the UN Food and Agriculture Organisation as far back as 2008. “Most water withdrawn comes from fossil deep aquifers, and some predictions suggest that these resources may not last more than about 25 years.”
In a country that rarely sees rain, the habit of draining groundwater, like the Berain factory does, could prove perilous: groundwater makes up an estimated 98% of naturally occurring fresh water in Saudi Arabia.
Indeed, oil may have built the modern Saudi state, but a lack of water could destroy it if drastic solutions aren’t found soon.
The emergency seems invisible in Riyadh, which is undergoing a construction boom as more buildings creep upwards to join a collection of towering skyscrapers.
It’s the desert. Obviously, water is a natural constraint by Dr Rebecca Keller
Although everyone knows this city in the desert owes its existence to the discovery of oil in 1938, fewer realise water was just as important. Decades of efforts to make the desert bloom to feed the city’s population have resulted in agricultural projects to grow water-intensive crops such as wheat, on farmland meted out to figures favoured by the royal family.
While many questions the accuracy of the kingdom’s optimistic estimates of its own oil reserves, the looming threat of a lack of water could prove to be an even bigger problem. Saudi Arabia consumes double the world average of water per person, 263 litres per capita each day and rising, amid a changing climate that will strain water reserves.
In March, the Kingdom launched the Qatrah programme to demand citizens drastically cut their water use. Its aim is to ration water to 200 litres per person per day by 2020 and 150 litres by 2030.
It has also tried to reform the water-hungry agriculture industry, reducing government incentives for cereal production. The overall amount of irrigated farmland still hasn’t declined, though, as producers switch to more profitable crops that still require large amounts of water. Almarai, a major food producer, has begun buying up deserted land in the US, on plots near Los Angeles and in Arizona, and in Argentina, in order to grow water-rich alfalfa to feed its dairy cows.
The Saudi Arabian National Transformation Plan, also known as Vision 2020 – a subset of the Vision 2030 initiative intended to diversify the Kingdom’s economy away from oil – aims to reduce the amount of water pulled from underground aquifers for use in agriculture. It seeks to employ 191% of these water resources for farming, down from the current estimates of 416% of water available.
“This means that Saudi Arabia is using more than four times the water that renews on average – and that’s in Vision 2020,” says Dr Rebecca Keller from Stratfor – a private intelligence and geopolitical analysis firm – who says she was shocked after learning about the country’s water use. “Technically they’re using fossil water, which renews at a really, really slow rate. The sheer volume of overuse stood out to me.”
Desalinating sea water has long been seen as a silver bullet against the growing threat of water shortages across the Middle East. Saudi Arabia leads the world in the volume of desalinated water it produces and now operates 31 desalination plants. Desalinated water, as distinct from naturally occurring fresh water, makes up 50% of water consumed in Saudi Arabia. The remaining 50% is pulled from groundwater.
It comes as at a high-energy cost, however. According to the International Energy Agency, in 2016 desalination accounted for 3% of the Middle East’s water supply but 5% of its overall energy cost. Researchers at King Abdelaziz University in Jeddah estimate that the demand for desalinated water increases by roughly 14% each year, but add that “desalination is a very costly process and is not sustainable”. Desalination plants also harm the surrounding environment, pumping pollutants into the air and endangering marine ecosystems with their run-off.
A recent push towards using solar power rather than fossil fuels to desalinate means that the first commercial plant is expected to be up and running at 2021 at the earliest, although it reportedly remains behind schedule.
Keller says Saudi Arabia’s evolving use of desalination technology could also alter their relationship with other countries in the region, in particular, Israel. “They’re producing the most cutting-edge technology for desalination, especially at scale,” she said. “As we see [both countries] having more geopolitical things in common in terms of their attitude to Iran, there’s more room for this relationship to grow, and the Saudi water sector is something that could benefit from this cooperation.”
The toughest challenge of all remains switching consumption habits to avoid an impending water emergency. The kingdom is pressing ahead with its Red Sea Project, a tourism haven the size of Belgium that aims to attract a million visitors annually to its unspoiled beaches and 50 new hotels. Such mammoth construction means growing water use, with current estimates that the string of resorts will use 56,000 cubic metres of water per day.
“It’s the desert,” said Keller. “Obviously water is a natural constraint.”
ISTANBUL (Reuters) – Turkey has started filling a huge hydroelectric dam on the Tigris river, a lawmaker and activists said, despite protests that it will displace thousands of people and risks creating water shortages downstream in Iraq.
Citing satellite images, they said that water was starting to build up behind the Ilisu dam, a project that has been decades in the making and which aims to generate 1,200 megawatts of electricity for southeast Turkey.
Turkish officials have not commented on work at the dam. Turkey’s State Hydraulic Works (DSI), which oversees dam projects, referred questions to the Presidency, and the Agriculture and Forestry Ministry was not available to comment.
However, President Tayyip Erdogan said earlier this year that Turkey would start filling the Ilisu dam in June, a year after it briefly held backwater before backing down following complaints from Iraq about reduced water flows in mid-summer.
The dam, which first gained Turkish government approval in 1997, is a key part of Turkey’s Southeastern Anatolia Project, designed to improve its poorest and least developed region.
Iraq says the dam will create water shortages by reducing flows in one of two rivers which the country depends on for much of its supplies. Around 70% of Iraq’s water supplies flow from neighboring countries, especially via the Tigris and Euphrates rivers which run through Turkey.
Satellite images from the past two weeks show the dam has started holding water, said Necdet Ipekyuz, a lawmaker from Turkey’s pro-Kurdish Peoples’ Democratic Party (HDP). He said a road in the area has already been submerged.
“They are taking steps slowly to decrease the reactions to water being held. That is why they are not informing the public,” he said, adding that several HDP lawmakers tried to visit the dam in July but were prevented by police.
Environmental campaigners have unsuccessfully challenged the dam project at the European Court of Human Rights on the grounds it would damage the country’s cultural heritage.
The rising waters of the dam are also expected to eventually submerge the 12,000-year-old town of Hasankeyf. Residents are being moved from the ancient town to a “New Hasankeyf” nearby, while historic artefacts have also been transported out of the area.
A group of NGOs, lawmakers and labor unions shared satellite images of the dam showing the increase in water levels between July 19-29.
“The current situation is strengthening the idea that the valves have been closed permanently,” the group, known as Hasankeyf Coordination, said in a statement.
“Because the dam lake is growing every day, the people who live in these areas are worried. They cannot know when the water will reach their residential or agricultural areas.”
The Iraqi government said in a statement that Turkish and Iraqi officials had discussed the water resources of the two rivers in Baghdad on Wednesday to see how they could “serve the interests of both countries”.
Turkey proposed setting up a joint research center in Baghdad for water management and to work together on some agriculture plantations in Iraq, as well as projects for development of drinking water infrastructure.

The European Court of Human Rights in February dismissed the case brought by environmental campaigners to block the dam project, saying heritage protection is the responsibility of Turkish authorities and it had no jurisdiction.
The government needs to make an announcement, even if the dam were being filled for a trial run, said HDP’s Ipekyuz. “They are trying to tie a belt around the Tigris river’s neck and suffocate it,” he said.
