1. What is the greenhouse effect?

In a greenhouse, sunlight enters, and heat is retained. The greenhouse effect describes a similar phenomenon on a planetary scale but, instead of the glass of a greenhouse,  certain gases are increasingly raising global temperatures.

The surface of the Earth absorbs just under half of the sun’s energy, while the atmosphere absorbs 23 per cent, and the rest is reflected back into space. Natural processes ensure that the amount of incoming and outgoing energy is equal, keeping the planet’s temperature stable.

However, human activity is resulting in the increased emission of so-called greenhouse gases (GHGs) which, unlike other atmospheric gases such as oxygen and nitrogen, becomes trapped in the atmosphere, unable to escape the planet. This energy returns to the surface, where it is reabsorbed.

Because more energy enters than exits the planet, surface temperatures increase until a new balance is achieved. 

2. Why does the warming matter?

This temperature increase has long-term, adverse effects on the climate, and affects a myriad of natural systems. Effects include increases in the frequency and intensity of extreme weather events – including flooding, droughts, wildfires and hurricanes – that affect millions of people and cause trillions in economic losses.

“Human-caused greenhouse gas emissions endanger human and environmental health,” says Mark Radka, Chief of the UN Environment Programme’s (UNEP) Energy and Climate Branch. “And the impacts will become more widespread and severe without strong climate action.”

GHG emissions are critical to understanding and addressing the climate crisis: despite an initial dip due to COVID-19, the latest UNEP Emissions Gap Report shows a rebound, and forecasts a disastrous global temperature rise of at least 2.7 degrees this century, unless countries make much greater efforts to reduce emissions.

The report found that GHG emissions need to be halved by 2030, if we are to limit global warming to 1.5°C compared to pre-industrial levels by the end of the century.

Carbon dioxide levels continue at record levels, despite the economic slowdown caused by the COVID-19 pandemic.

3. What are the major greenhouse gases?

Water vapour is the biggest overall contributor to the greenhouse effect. However, almost all the water vapour in the atmosphere comes from natural processes.

Carbon dioxide (CO2), methane and nitrous oxide are the major GHGs to worry about. CO2 stays in the atmosphere for up to 1,000 years, methane for around a decade, and nitrous oxide for approximately 120 years.

Measured over a 20-year period, methane is 80 times more potent than CO2 in causing global warming, while nitrous oxide is 280 times more potent.

4. How is human activity producing these greenhouse gases?

Coal, oil, and natural gas continue to power many parts of the world. Carbon is the main element in these fuels and, when they’re burned to generate electricity, power transportation, or provide heat, they produce CO2.

Oil and gas extraction, coal mining, and waste landfills account for 55 per cent of human-caused methane emissions. Approximately 32 per cent of human-caused methane emissions are attributable to cows, sheep and other ruminants that ferment food in their stomachs. Manure decomposition is another agricultural source of the gas, as is rice cultivation. 

Human-caused nitrous oxide emissions largely arise from agriculture practices. Bacteria in soil and water naturally convert nitrogen into nitrous oxide, but fertilizer use and run-off add to this process by putting more nitrogen into the environment.

Fluorinated gases – such as hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride – are GHGs that do not occur naturally. Hydrofluorocarbons are refrigerants used as alternatives to chlorofluorocarbons (CFCs), which, having depleted the ozone layer,were phased out thanks to the Montreal Protocol. The others have industrial and commercial uses.

While fluorinated gases are far less prevalent than other GHGs and do not deplete the ozone layer like CFCs, they are still very powerful. Over a 20-year period, the global warming potential of some fluorinated gases is up to 16,300 times greater than that of CO2.

Wind farms generate electricity and reduce reliance on coal-powered energy.

5. What can we do to reduce GHG emissions?

Shifting to renewable energy, putting a price on carbon, and phasing out coal are all important elements in reducing GHG emissions. Ultimately, stronger emission-reduction targets are necessary for the preservation of long-term human and environmental health.

“We need to implement strong policies that back the raised ambitions,” says Mr. Radka. “We cannot continue down the same path and expect better results. Action is needed now.”

During COP26, the European Union and the United States launched the Global Methane Pledge, which will see over 100 countries aim to reduce 30 per cent of methane emissions in the fuel, agriculture and waste sectors by 2030.

Despite the challenges, there is reason to be positive. From 2010 to 2021, policies were put in place  to lower annual emissions by 11 gigatons by 2030 compared to what would have otherwise happened. Individuals can also join the UN’s #ActNow campaign for ideas to take climate-positive actions.

By making choices that have less harmful effects on the environment, everyone can be a part of the solution and influence change. Speaking up is one way to multiply impact and create change on a much bigger scale.

UNEP’s role in reducing GHGs

UNEP has outlined its six-sector solution, which can reduce 29–32 gigatons of carbon dioxide by 2030 to meet the 1.5°C warming limit. The six sectors identified are: energy; industry; agricultureand food; forests andland use; transport; and buildings and cities.UNEP also maintains an online “Climate Note,” a tool that visualizes the changing state of the climate with a baseline of 1990.Through its other multilateral environmental agreements and reports, UNEP raises awareness and advocates for effective environmental action. UNEP will continue to work closely with its 193 Member States and other stakeholders to set the environmental agenda and advocate for a drastic reduction in GHG emissions.

Up to 70% of Children in Developing Countries to Be Left Unable to Read?

Published

The alarm bell has been rung by the UN Secretary General, António Guterres, in his message on the International Day of Education, marked on 24 January 2022.

In fact, some 1.6 billion school and college students had their studies interrupted at the peak of the COVID-19 pandemic — and it’s not over yet, said Guterres, adding that today, school closures continue to disrupt the lives of over 31 million students, “exacerbating a global learning crisis.”

The UN Education, Sciencia and Culture Organisation (UNESCO), the World Bank and the UN Children Fund (UNICEF) have quantified the economic dimension of this drama.

Giant losses

“This generation of students now risk losing 17 trillion US dollars in lifetime earnings in present value, or about 14 percent of today’s global Gross Domestic Product (GDP), as a result of COVID-19 pandemic-related school closures.”

The State of the Global Education Crisis: A Path to Recovery report,  released in December 2021, shows that in low- and middle-income countries, the share of children living in Learning Poverty – already 53 percent before the pandemic – could potentially reach 70 percent given the long school closures and the ineffectiveness of remote learning to ensure full learning continuity during school closures.

According to the three world bodies’ report, simulations estimating that school closures resulted in significant learning losses are now being corroborated by real data.

And it provides some specific examples: regional evidence from Brazil, Pakistan, rural India, South Africa, and Mexico, among others, show substantial losses in maths and reading.

Analysis shows that in some countries, on average, learning losses are roughly proportional to the length of the closures. However, there was great heterogeneity across countries and by subject, students’ socioeconomic status, gender, and grade level.

“For example, results from two states in Mexico show significant learning losses in reading and in maths for students aged 10-15. The estimated learning losses were greater in maths than reading, and affected younger learners, students from low-income backgrounds, as well as girls disproportionately.”

Inequities of education, exacerbated

Learning to read is a milestone in every child’s life. Reading is a foundational skill, the report explains, adding that all children should be able to read by age 10. Reading is a gateway for learning as the child progresses through school – and conversely, an inability to read constraints opportunities for further learning.

“Beyond this, when children cannot read, it’s usually a clear indication that school systems aren’t well organised to help children learn in other areas such as maths, science, and the humanities either.”

And although it is possible to learn later in life with enough effort, children who don’t read by age 10 – or at the latest, by the end of primary school – usually fail to master reading later in their schooling career.

Even before COVID-19 disrupted education systems around the world, it was clear that many children around the world were not learning to read proficiently, according to the report. Even though the majority of children are in school, a large proportion are not acquiring fundamental skills.

“Moreover, 260 million children are not even in school. This is the leading edge of a learning crisis that threatens countries’ efforts to build human capital and achieve the Sustainable Development Goals (SDGs).”

No human capital

Without foundational learning, students often fail to thrive later in school or when they join the workforce.

“They don’t acquire the human capital they need to power their careers and economies once they leave school, or the skills that will help them become engaged citizens and nurture healthy, prosperous families. Importantly, a lack of foundational literacy skills in the early grades can lead to intergenerational transmission of poverty and vulnerability.”

As a major contributor to human capital deficits, the learning crisis undermines sustainable growth and poverty reduction.

To spotlight this crisis, the World Bank and the UNESCO Institute for Statistics jointly constructed the concept of Learning Poverty and an accompanying indicator.

“Learning poverty means being unable to read and understand a simple text by age 10.”

Aggravating global learning crisis

COVID-19 is now wreaking havoc on the lives of young children, students, and youth. The disruption of societies and economies caused by the COVID-19 pandemic is aggravating the global learning crisis and impacting education in unprecedented ways.

Learning poverty to rise

With more than a complete year of schooling lost in many parts of the world, learning poverty is estimated to rise to 63 percent in developing countries.

Gaping inequalities

UNESCO says that this fourth International Day of Education is marked “as our world stands at a turning point: gaping inequalities, a damaged planet, growing polarisation and the devastating impact of the global pandemic put us before a generational choice: Continue on an unsustainable path or radically change course.”

Education is key to charting the course towards more justice and sustainability, but it is “failing millions of children, youth and adults, increasing their exposure to poverty, violence and exploitation,” adds UNESCO.

Education, a human right

And here goes a needed reminder: the right to education is enshrined in article 26 of the Universal Declaration of Human Rights.

The Declaration calls for “free and compulsory elementary education.”

The Convention on the Rights of the Child, adopted in 1989, goes further to stipulate that countries “shall make higher education accessible to all.”

Challenges

“Education offers children a ladder out of poverty and a path to a promising future.”

But about 258 million children and adolescents around the world do not have the opportunity to enter or complete school, and 617 million children and adolescents cannot read and do basic maths…

And less than 40% of girls in sub-Saharan Africa complete lower secondary school and some four million children and youth refugees are out of school.

“Their right to education is being violated and it is unacceptable,” warns the United Nations.

“Without inclusive and equitable quality education and lifelong opportunities for all, countries will not succeed in achieving gender equality and breaking the cycle of poverty that is leaving millions of children, youth and adults behind.”

Bringing Dry Land in the Sahel Back to Life

Published

Those trying to grow crops in the Sahel region are often faced with poor soil, erratic rainfail and long periods of drought. However, the introduction of a state-of-the art heavy digger, the Delfino plough, is proving to be, literally, a breakthrough.

As part of its Action Against Desertification (AAD) programme, the FAO has brought the Delfino to four countries in the Sahel region – Burkina Faso, Niger, Nigeria and Senegal – to cut through impacted, bone-dry soil to a depth of more than half a metre.

The Delfino plough is extremely efficient: one hundred farmers digging irrigation ditches by hand can cover a hectare a day, but when the Delfino is hooked to a tractor, it can cover 15 to 20 hectares in a day.

Once an area is ploughed, the seeds of woody and herbaceous native species are then sown directly, and inoculated seedlings planted. These species are very resilient and work well in degraded land, providing vegetation cover and improving the productivity of previously barren lands. 

In Burkina Faso and Niger, the target number of hectares for immediate restoration has already been met and extended thanks to the Delfino plough. In Nigeria and Senegal, it is working to scale up the restoration of degraded land.

This technology, whilst impressive, is proving to be successful because it is being used in tandem with traditional farming techniques.

“In the end the Delfino is just a plough. A very good and suitable plough, but a plough all the same,” says Moctar Sacande, Coordinator of FAO’s Action Against Desertification programme. “It is when we use it appropriately and in consultation and cooperation that we see such progress.”

The half-moon is a traditional Sahel planting method which creates contours to stop rainwater runoff, improving water infiltration and keeping the soil moist for longer. This creates favourable micro-climate conditions allowing seeds and seedlings to flourish.

The Delfino creates large half-moon catchments ready for planting seeds and seedlings, boosting rainwater harvesting tenfold and making soil more permeable for planting than the traditional – and backbreaking – method of digging by hand.

“The whole community is involved and has benefitted from fodder crops such as hay as high as their knees within just two years”, says Mr. Sacande. “They can feed their livestock and sell the surplus, and move on to gathering products such as edible fruits, natural oils for soaps, wild honey and plants for traditional medicine”.

Women taking the lead

According to Nora Berrahmouni, who was FAO’s Senior Forestry Officer for the African Regional Office when the Delfino was deployed, the plough will also reduce the burden on women.

“The season for the very hard work of hand-digging the half-moon irrigation dams comes when the men of the community have had to move with the animals. So, the work falls on the women,” says Ms. Berrahmouni.

Because the Delfino plough significantly speeds up the ploughing process and reduces the physical labour needed, it gives women extra time to manage their multitude of other tasks.

The project also aims to boost women’s participation in local land restoration on a bigger scale, offering them leadership roles through the village committees that plan the work of restoring land. Under the AAD programme, each site selected for restoration is encouraged to set up a village committee to manage the resources, so as to take ownership right from the beginning.

“Many women are running the local village committees which organise these activities and they are telling us they feel more empowered and respected,” offers Mr. Sacande.

Respecting local knowledge and traditional skills is another key to success. Communities have long understood that half-moon dams are the best way of harvesting rainwater for the long dry season. The mighty Delfino is just making the job more efficient and less physically demanding.

Millions of hectares lost to the desert, forests under threat

And it is urgent that progress is made. Land loss is a driver of many other problems such as hunger, poverty, unemployment, forced migration, conflict and an increased risk of extreme weather events related to climate change.

In Burkina Faso, for example, a third of the landscape is degraded. This means that over nine million hectares of land, once used for agriculture, is no longer viable for farming.

It is projected that degradation will continue to expand at 360 000 hectares per year. If the situation is not reversed, forests are at risk of being cleared to make way for productive agricultural land.

Africa is currently losing four million hectares of forest every year for this reason, yet has more than 700 million hectares of degraded land viable for restoration. By bringing degraded land back to life, farmers do not have to clear additional forest land to turn into cropland for Africa’s rising population and growing food demands.

When Mr. Sacande talks about restoring land in Africa, the passion in his voice is evident. “Restoring degraded land back to productive good health is a huge opportunity for Africa. It brings big social and economic benefits to rural farming communities,” he says. “It’s a bulwark against climate change and it brings technology to enhance traditional knowledge.”

From Milan to Glasgow, Young Moroccans Commit to Fighting Climate Change

Published

on

© United Nations MoroccoYoung Moroccan climate activists and entrepreneurs are taking a group photo with Sylvia Lopez-Ekra in Morocco.Saturday, January 22, 2022UN News

Behind all these initiatives, are the young men and women featured in “From Milan to Glasgow: Moroccan Youth Leaders in the Spotlight“, a new campaign launched by the United Nations team in Morocco to empower young people to take climate action and reduce the harmful carbon emissions that are dangerously heating the planet.

For the United Nations Resident Coordinator in Morocco, Sylvia Lopez-Ekra, the new campaign is a “bet on the importance of partnering with Moroccan youth invested in climate issues.”

Tipping the balance

One of the activists featured is Manal Bidar, an 18-year-old from the city of Agadir, who believes “it is young people who can tip the balance to the right side in the fight against climate change.”

She first got involved in climate and environment action at 13, when she joined a group of friends from a local club, to clean a beach.

She is now an ambassador for the African Youth Climate Hub, a platform that brings together activists from the continent, and serves as an advisor to the Global Center on Adaptation (GCA), an international non-profit dedicated to promote climate-resilience around the world. 

‘Fight of our lives’

Like Ms. Bidar, Hasnae Bakhchouch, a 22-year-old student from Rabat, is taking action to tackle the impact of climate change. 

“With its adverse effects on biodiversity and the health of living beings, climate change jeopardizes societies and can cause conflicts over access to natural resources”, she says.

Ms. Bakhchouch was a National Coordinator of the Moroccan youth delegation to the UN Conference of Youth on Climate, held in September 2021 in Milan, Italy. 

She explains that the goal was to draft recommendations for the 26th UN Climate Change conference (COP26), which was held in Glasgow, Scotland, a couple of months later. 

The Conference closed with a “compromise” deal, which the UN Secretary-General, António Guterres, said was simply “not enough”. 

At the time, the UN chief encouraged young people and everyone leading the charge, to keep fighting. 

“We are in the fight of our lives, and this fight must be won”, he said. 

From coffee to bricks

One day, while enjoying a cup of coffee, Hamza Laalej, a 23-year-old Moroccan student from Meknes, asked himself if there was a way to recycle the large amount of coffee grounds that end up in the garbage every day. 

Months later, Mr. Laalej managed to turn his idea into a viable green business, where one of the main products is an eco-friendly brick made with a mix of coffee grounds and regular clay.

“Inspired by the Moroccan craft tradition, the production of these bricks relies on [using less] heating, thus helping to reduce greenhouse gas emissions”, he explains. 

Since then, he has teamed up with 23-year-old Moroccan, Nour El Houda Ben Khoudja, to launch a company that specializes in the collection, sorting, and transformation of coffee grounds into building materials and decoration products.

“You don’t have to wait for the perfect time to start [a green business]. It’s the obstacles you encounter along the way that make business creation an inspiring and fruitful adventure”, he says. 

Green entrepreneurs

A roundtable organized last November, during the launch of this UN campaign, saw other young people present their green start-up projects.

The goal is to provide companies operating in the Moroccan port of Tangier Med, with a renewable alternative to meet their energy needs.

Younes Ouazri presented an ecological and energy-efficient construction method to build homes, including seasonal residences and tourism resorts, using locally sourced materials. 

Hicham Zouaoui and Otman Harrak spoke about their carpooling app, that currently allows some 400,000 Moroccans to travel across the Kingdom, helping save on transportation costs and reducing CO2 emissions.

For his part, Seifeddin Laalej heads a start-up that specializes in recycling plastic waste to manufacture building materials, which he sells all over the country.

“It is important that young people believe in their potential and launch their own projects based on their skills and professional networks”, he said. 

A key player

According to the UN Resident Coordinator, “thanks to its climate policy for the past years, Morocco has become a key leader on initiatives for climate action.”

Through an ambitious greenhouse gas emissions reduction programme and strategies for the preservation of natural resources, Morocco intends to reduce its greenhouse gas emissions by 45.5 per cent by 2030 and achieve a 52 per cent share of renewable energy in its energy mix in the same year. 

The country is currently one of the few nations with a nationally determined contribution (NDC) in line with the global target of 1.5°C.
