ROME, May 8 2023 (IPS)* – Less than a decade ago, Africa was home to 60-65% of the world’s uncultivated arable land and 10% of renewable freshwater resources, as reported by the African Union in 2016, while concluding that African farmers could feed the world.
Is it still the case?

A major consequence is that that very percentage (60-65%) of the world’s uncultivated and arable land is now affected by degradation, with nearly three million hectares of forest lost… every single year.
Great walls
The steadily advancing degradation and desertification of major African regions have led the continent to build great green walls.
One of them – the Great Green Wall, is the largest living structure on the Planet, one that stretches over 8.000 kilometres across Africa, aiming at restoring the continent’s degraded landscapes and transforming millions of lives in the Sahel, and ushering in a new era of sustainability and economic growth.
Launched in 2007 by the African Union, this African-led Great Green Wall Initiative. The project is being implemented across 22 African countries and is expected to revitalise thousands of communities across the continent.
It is about “helping people and nature cope with the growing impact of the climate emergency and the degradation of vital ecosystems, and to keep the Sahara desert from spreading deeper into one of the world’s poorest regions,” according to the UN Environment Programme (UNEP).
Vast tracts of land along the Great Green Wall have already been restored by local communities. And so far, 80% of the 19 billion US dollars have been pledged, as reported by the UN Convention to Combat Desertification (UNCCD).
But not enough…
The extraneous factors that have been pushing Africa towards the abyss of extremely severe droughts, unprecedented floods, the advancing degradation of its land and water resources, have led this continent on Earth to rush to build more and longer and larger walls.
For instance, the Southern Africa region is currently busy preparing a similar programme, with all 16 countries in the Southern African Development Community (SADC) committed to accelerating multi-sectoral transformation through a regional initiative inspired by the Great Green Wall in the Sahel, or SADC Great Green Wall Initiative (GGWI).
The SADC member countries are: Angola, Botswana, Comoros, DR Congo, Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Tanzania, Zambia and Zimbabwe.
A wall for Southern Africa
Their Initiative aims to create productive landscapes in the Southern Africa region that contribute to regional socially inclusive economic prosperity and environmental sustainability.
Together with member countries and key partners the goal is to initiate multi sectoral partnerships and to acquire pledges of an indicative 27 billion US dollars by 2025.
10 Million square kilometres at risk of desertification
Covering a total land area of 10 million square kilometres, Southern Africa faces immediate effects of desertification, land degradation and drought, as well as challenges driven by climate change, biodiversity loss, and unsustainable development practices in agriculture, energy and infrastructure sectors, reports the UN Convention to Combat Desertification (UNCCD).
“The Great Green Wall is part of a broader economic and development plan – if we restore land but are not able to reap the benefits of that healthy and restored land due to lack of access to renewable energy and infrastructure, hindering access to markets and livelihoods, then we are only halfway there with our vision,” on this said UNCCD’s Louise Baker.
And a great wall for the Middle East
In addition to the above two new natural wonders, there is another one: the Middle East Green Initiative, a regional effort led by Saudi Arabia to mitigate the impact of climate change on the region and to collaborate to meet global climate targets.
50 billion trees?
It aims at planting 50 billion trees across the Middle East, equivalent to 5% of the global afforestation target, and to restore 200 million hectares of degraded land.
A fifth (10 billion) trees will be planted within Saudi Arabia’s borders, with the remaining 40 billion set to be planted across the region in the coming decades.
Across the Middle East and North Africa, extreme weather events including droughts and heavy rains will become more common in the region if global temperatures continue to increase, according to the Saudi-led project.
A green corridor for East Africa… and elsewhere
In addition to developing an Eastern Africa corridor soon, other similar initiatives under the umbrella of the African Union’s NEPAD are ongoing, such as the African Forest Landscape Restoration Initiative (AFR100).
In 2015, AFR100 was founded in Durban by a group of 10 African countries, each committing to restore a certain number of hectares of degraded landscapes within their borders.
Twenty-eight African countries have now committed to restoring 113 million hectares, which, if achieved, will exceed the initiative’s namesake goal of 100 million hectares across the continent under restoration by 2030.
Not only trees
Forest landscape restoration is more than just planting trees,” said Mamadou Diakhite, leader of the AFR100 Secretariat.
On a continent that is expected to account for half the global population growth by 2050, reducing and sequestering greenhouse gas emissions is a welcome byproduct of returning those natural landscapes to health and profitability; but it’s not the first focus, reported Gabrielle Lipton, Landscape News Editor-in-Chief.
“Restoring landscapes that have been degraded by the effects of climate change and human development through planting trees and encouraging sustainable farming and herding must first and foremost provide food, jobs and homes for people, as well as preserve their cultures that are based on the products of their lands.”
Moreover, as more than 1 in 5 people in Africa are undernourished, and forced migration across country borders increases due to climate change and conflict, African economies continue to struggle hard to create jobs for young people.
Any chance that Africa recovers soon from the impacts of so much extraneous damage, which this continent of nearly 1.4 billion humans continues to struggle to reverse?
Desertification is the shifting of sands and other earth’s surface materials threatening land arability and farming food production. Infrastructure and the built environment are impacted. It was there until today, but lately, escalating Desertification of Earth demands urgent attention.

Escalating Desertification Of Earth Demands Urgent Attention

A Report On The National Geographic Website Suggests That Degradation Has Impacted Over 75% Of The Earth’s Landmass, Posing A Serious Threat To The Survival Of 3.2 Billion Individuals. The Phenomenon Of Desertification Serves As A Cautionary Message From Nature To Humanity.
Washington, D.C. (Business Northeast) – A large portion of the Earth’s land surface is already affected by degradation. According to the assessment report, more than 75% of the earth’s land area is degrading and threatening the lives of 3.2 billion people. Some land has become deserts, some land has been contaminated, and forests have been cut down into agricultural land. These are the main causes of species extinction. If the land continues to desertify, by 2050, 95% of the earth’s land area will become barren. The report also shows that food production may collapse in many places in the future, and hundreds of millions of people will be forced to relocate.
The Earth Is Changing Extremely
With the increase in the number of people on the planet and the development of the economy, the environmental pollution and the greenhouse effect of the planet have become very serious. Land, ecology and climate are changing. For example, Australia’s unstoppable forest fires, overheated or cold climates in comfortable areas, and extinct animals are increasing every year.
According to the “Weather” data, there are three kinds of bird extinction in 2018 alone, and there will be more and more endangered creatures in the future.
“Land degradation, biodiversity loss, and climate change are three different faces of the same central challenge: the increasingly dangerous impact of our choices on the health of our natural environment,” said Sir Robert Watson, chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
Over the past 300 years, 87% of the world’s wetlands have disappeared, of which about 54% occurred after 1900. In order to plant oil palms, humans have continuously destroyed wetlands and severely damaged the ecology in the Congo region of Southeast Asia and Africa.
Carbon Dioxide Can Be Stored In The Soil
Restoring land to pastures, food crops, or woods can convert enough carbon into biomass to stabilize carbon dioxide emissions for 15 to 20 years. Plants absorb carbon dioxide from the air and combine it with sunlight to convert it into energy that plants can use. Not all carbon is consumed by plants. Some are stored in the soil in the state of humin, this stable carbon molecule can be kept in the soil for centuries.
The United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, specifically in Africa (UNCCD) is a convention influenced by national action plans and desertification and mitigate, which incorporates long-term strategies and Partnership arrangements.
“We have lost the biological function of soils. We have got to reverse that,” said Barron J. Orr, lead scientist for the UN Convention to Combat Desertification. “If we do it, we are turning the land into the big part of the solution for climate change.” The core of this idea is to solve the growing problem of desertification.
Govern The Desert To Save Green Land
NASA published an article in February 2019, pointing out that the earth’s green space has increased by 5% compared with 20 years ago, and the increase in plant area is equivalent to an Amazon rainforest. Among them, China and India have made the greatest contribution to global greening. This result surprised all walks of life. 42% of China’s huge contribution to the global greening trend comes from plans to protect and expand forests. and 82% of the greening seen in India – comes from intensive cultivation of food crops.
“China and India account for one-third of the greening, but contain only 9% of the planet’s land area covered in vegetation – a surprising finding, considering the general notion of land degradation in populous countries from overexploitation,” said Chi Chen of the Department of Earth and Environment at Boston University, in Massachusetts, and lead author of the study.
Many factors will affect future greening trends, including global scale and the local human level. For example, India’s groundwater irrigation has boosted food production. If groundwater is depleted, this trend may change. Any policy and resources will affect our future. If we want to slow down desertification and save the green earth, we must reduce man-made destruction and environmental pollution. Don’t give up on small details, use long-term efforts to restore our land.
The forthcoming World Economic Forum Annual Meeting will answer some questions: How can the Middle East and North Africa manage the region’s water crisis? In the meantime, let us also see what it is all about.
How can the Middle East and North Africa manage the region’s water crisis?
Nearly 90% of children in the region live in areas of high or extremely high water stress.
The Middle East and North Africa (MENA) is one of the most water-scarce regions in the world.
For years, the water crisis has exacerbated conflict and political tensions. Moreover, the issue continues to significantly impact the health and wellbeing of people in the area, especially women and children. In fact, according to UNICEF, nearly 90% of children in the region live in areas of high or extremely high water stress.
As global temperatures rise and the climate crisis accelerates, the MENA water crisis is expected to worsen – and impact economic growth. The World Bank found that climate-related water scarcity could lead to economic losses equaling up to 14% of the region’s GDP over the next 30 years.
Yet technological innovations and advanced water-management systems are helping to mitigate the situation. This includes the development of major desalination plants, as well as the implementation of sustainable agriculture and water-recycling programmes.
Ahead of the World Economic Forum’s 2023 Annual Meeting in Davos, Switzerland, four industry leaders share their thoughts on the MENA water crisis and detail ongoing efforts to help the region overcome water scarcity in the coming years.
Peter Terium, Chief Executive Officer, ENOWA; Managing Director, Energy, Water & Food, NEOM
“In NEOM, located in the north-west of Saudi, underground water has been more and more used for agriculture and irrigation due to the increase in population in the region. This has led to a drop in the ground water table and has dried up many of the springs in the area, changing the face of the environment. The aquifers no longer have the capability to regenerate themselves due to the water demand and open dumping of wastewater on the land has led to pollution of this scarce resource.
“By replacing the underground water used for irrigation with the desalinated water, and processing the wastewater and recycling all water that normally goes to waste, we will rebalance the ecosystem and bring back the natural oasis in the region. ENOWA, NEOM’s energy and water subsidiary, is creating a circular water system. To realize this, we bring together innovation across the water value chain, and beyond.
“Globally, average water loss is about 30%. By using innovative technologies, ENOWA aims to reduce loss to 3% which reduces the overall infrastructure and costing for water. With smart monitoring technologies, 100% recycling of wastewater, and the production of clean industrial resources, we are maximizing the potential of water use in industry, farming and to rebalance nature.”
“With our circular approach, we are positively impacting NEOM’s flora and fauna, and we hope to amplify the positive impact across the world.

“Gulf Cooperation Council members are taking a multi-faceted approach to addressing water scarcity. Saudi Arabia’s Rabigh 3 Independent Water Plant produces 600,000 cubic metres of desalinated water a day using reverse osmosis. It can meet the needs of 1 million households and is recognised by Guinness World Records as the world’s largest reverse osmosis desalination plant.
“A region as dry as the Arabian Peninsula demands both innovation and efficiency. Bahrain’s agriculture relied exclusively on groundwater until 1985 when the government began treating wastewater for reuse. Today, recycled water covers 40% of the sector’s needs.
“Bahrain EDB focuses on attracting investments and building solutions that have a positive impact on issues like water scarcity, such as Pavilion Water – a water desalination specialist that produces fresh water with zero greenhouse gas emissions.
“Innovative farming is also helping produce more food with less water across the region. UAE-based start-up Smart Acres is a vertical indoor hydroponic farm that, compared to traditional methods, yields 20 times as much food while using a tenth of the land and 90% less water.
“International cooperation on research to solve water scarcity is already proving important, too. Oman, for example, is working with the Dutch government to introduce new ideas to the region, while the Middle East Desalination Centre in Muscat acts as a pioneering hub for research.”
Paddy Padmanathan, Vice-Chairman and Chief Executive Officer, ACWA Power
“Billions of people around the world lack adequate access to water, a basic need to sustain healthy life. The Middle East and North Africa is the worst off in terms of physical water stress receiving less rainfall than other regions but, yet having fast-growing, densely populated urban centres that require more water.
“Immediately the awareness of the issue needs to be heightened and consumption needs to be contained at 150 litres per day. But to even supply that low level of consumption, we need to keep innovating.
“We at ACWA Power continue to stretch technology to reduce energy, chemical and sophisticated consumables consumption by challenging conventional practices, increasing the use of big data, the phenomenal power of computing, advanced analytics, machine learning and artificial intelligence to reduce the cost of taking salt out of seawater (desalination) and by increasing the utilization of renewable energy also simultaneously reduce the carbon footprint of this energy intensive process to increase the provision of potable water at a progressively lower cost reducing the impact on climate change.
“With the track record of being the leading desalinator in the world, today dispatching 6.4 million cubic metres per day of desalinated water we are proud to have led the cost reduction challenge by bringing the cost of desalinated water from $2+ per cubic metres just a few years ago to less than $0.50 per cubic metres today.”
Majid Al Futtaim Holding
“With some of the highest per-capita water-consumption rates, a hot and dry climate, wasteful water infrastructure and a heavy reliance on greenhouse gas-producing desalination, MENA countries are particularly affected by water scarcity. The region’s rapid population growth has also led many countries to rely heavily on ever-depleting ground and surface water.
“At Majid Al Futtaim, we understand the scale of the issue and began addressing it as part of our sustainability strategy. We developed a clean water investment strategy that focuses on investing in water generation technology, local offsetting and the development of renewable-powered reverse osmosis desalination plants.
“As a diverse business operating across industries, Majid Al Futtaim is present in several sectors that are typically characterised by high water use. Yet the company takes several steps to effectively minimise its water footprint.
— Majid Al Futtaim Holding
“In our food and beverage retail sector, 80% of products are sourced locally from the region. We’ve also introduced micro irrigation systems and hydroponic farms into our supply chains to minimise water loss and promote sustainable farming. Meanwhile, in the fashion industry, which as a whole uses 93 billion cubic metres of water annually, Majid Al Futtaim engages with suppliers to offer sustainably made products designed to last longer as well as be re-used or recycled.
“Majid Al Futtaim also institutes sustainable water management systems into its building and community development sector. This includes, for instance, the use of on-site water treatment technologies and sustainable gardening practices.”
MADRID, Dec 1 2022 (IPS) – Drought is one of the ‘most destructive’ natural disasters in terms of the loss of life, arising from impacts, such as wide-scale crop failure, wildfires and water stress.
In other words, droughts are one of the “most feared natural phenomena in the world;” they devastate farmland, destroy livelihoods and cause untold suffering, as reported by the world’s top specialised bodies: the UN Convention to Combat Desertification (UNCCD).
They occur when an area experiences a shortage of water supply due to a lack of rainfall or lack of surface or groundwater. And they can last for weeks, months or years.
Exacerbated by land degradation and climate change, droughts are increasing in frequency and severity, up 29% since 2000, with 55 million people affected every year.
The impacts of climate change are often felt through water – more intense and frequent droughts, more extreme flooding, more erratic seasonal rainfall and accelerated melting of glaciers – with cascading effects on economies, ecosystems and all aspects of our daily lives, Petteri Taalas, WMO Secretary-General
By 2050, droughts may affect an estimated three-quarters of the world’s population. This means that agricultural production will have to increase by 60% to meet the global food demand in 2050.
This means that about 71% of the world’s irrigated area and 47% of major cities are to experience at least periodic water shortages. If this trend continues, the scarcity and associated water quality problems will lead to competition and conflicts among water users, adds the Convention.
Most of the world already impacted
The alert is loud and strong and it comes from a number of the world’s most knowledgeable organisations.
To begin with, the World Meteorological Organization (WMO) on 29 November 2022 reported that most of the globe was drier than normal in 2021, with “cascading effects on economies, ecosystems and our daily lives.”
Water
Between 2001 and 2018, UN-Water reported that a staggering 74% of all-natural disasters were water-related.
Currently, over 3.6 billion people have inadequate access to water at least one month per year and this is expected to increase to more than five billion by 2050.
Moreover, areas that were unusually dry included South America’s Rio de la Plata area, where a persistent drought has affected the region since 2019, according to WMO’s The State of Global Water Resources report.
Drying rivers, lakes
In Africa, major rivers such as the Niger, Volta, Nile and Congo had below-average water flow in 2021.
The same trend was observed in rivers in parts of Russia, West Siberia and in Central Asia.
On the other hand, there were above-normal river volumes in some North American basins, the North Amazon and South Africa, as well as in China’s Amur river basin, and northern India.
Cascading effects
The impacts of climate change are often felt through water – more intense and frequent droughts, more extreme flooding, more erratic seasonal rainfall and accelerated melting of glaciers – with cascading effects on economies, ecosystems and all aspects of our daily lives, said WMO Secretary-General Petteri Taalas.
“Changes to Cryosphere water resources affect food security, human health, ecosystem integrity and maintenance, and lead to significant impacts on economic and social development”, said WMO, sometimes causing river flooding and flash floods due to glacier lake outbursts.
The cryosphere – namely glaciers, snow cover, ice caps and, where present, permafrost – is the world’s biggest natural reservoir of freshwater.
Soils
Being water –or rather the lack of it– a major cause-effect of the fast-growing deterioration of natural resources, and the consequent damage to the world’s food production, the theme of World Soil Day 2022, marked 5 December, is “Soils: Where food begins.”
18 naturally occurring chemical elements are essential to plants. Soils supply 15.
Agricultural production will have to increase by 60% to meet the global food demand in 2050.
33% of soils are degraded.
Dangerously poisoned
In addition to the life of humans, animals, and plants, one of the sectors that most depend on water–crops is now highly endangered.
Indeed, since the 1950s, reminds the United Nations, innovations like synthetic fertilisers, chemical pesticides and high-yield cereals have helped humanity dramatically increase the amount of food it grows.
“But those inventions would be moot without agriculture’s most precious commodity: fresh water. And it, say researchers, is now under threat.”
Moreover, pollution, climate change and over-abstraction are beginning to compromise the lakes, rivers, and aquifers that underpin farming globally, reports the UN Environment Programme (UNEP).
Salinised and plastified
Such is the case, among many others, of the growing salinisation and ‘plastification’ of the world’s soils.
In fact, currently, it is estimated that there are more than 833 million hectares of salt-affected soils around the globe (8.7% of the planet). This implies the loss of soil’s capacity to grow food and also increasing impacts on water and the ability to filter pollution.
Soil salinisation and sodification are major soil degradation processes threatening ecosystems and are recognised as being among the most important problems at a global level for agricultural production, food security and sustainability in arid and semi-arid regions, said the UN on occasion of the 2021 World Soil Day.
Wastewater
Among the major causes that this international body highlights is that in some arid areas, there has been an increase in the amount of wastewater used to grow crops.
“The problem can be exacerbated by flooding, which can inundate sewage systems or stores of fertiliser, polluting both surface water and groundwater.” Fertiliser run-off can cause algal blooms in lakes.
Meanwhile, the amount of freshwater per capita has fallen by 20% over the last two decades and nearly 60% of irrigated cropland is water-stressed.
The implications of those shortages are far-reaching: irrigated agriculture contributes 40% of total food produced worldwide.
Soils are highly living organisms
“Did you know that there are more living organisms in a tablespoon of soil than people on Earth?”
Soil is a world made up of organisms, minerals, and organic components that provide food for humans and animals through plant growth, explains this year’s World Soils Day.
Agricultural systems lose nutrients with each harvest, and if soils are not managed sustainably, fertility is progressively lost, and soils will produce nutrient-deficient plants.
Soil nutrient loss is a major soil degradation process threatening nutrition. It is recognised as being among the most critical problems at a global level for food security and sustainability all around the globe.
‘Hidden’ hunger
Over the last 70 years, the level of vitamins and nutrients in food has drastically decreased, and it is estimated that 2 billion people worldwide suffer from a lack of micronutrients, known as hidden hunger because it is difficult to detect.
“Soil degradation induces some soils to be nutrient depleted, losing their capacity to support crops, while others have such a high nutrient concentration that represents a toxic environment to plants and animals, pollutes the environment and causes climate change.”
The Horn of Africa has had years of drought, yet groundwater supplies are increasing – why?
The Horn of Africa – which includes Somalia, Ethiopia, Kenya and some surrounding countries – has been hit by increasingly frequent and devastating droughts. Despite this, it seems the region has an increasing amount of groundwater. And this water could help support drought-stricken rural communities.
That’s the key finding from our new research, in which we discovered that while overall rainfall is decreasing, an increase in “high-intensity” rainfall has led to more water being stored deep underground. It’s a paradoxical finding, yet one that may help one of the world’s most vulnerable regions adapt to climate change.
In the Horn of Africa, rural communities live in a constant state of water scarcity punctuated by frequent periods of food insecurity. People there rely on the “long rains” between March and May and the “short rains” between October and December to support their lives and livelihoods.
The drought is so severe that it is even affecting zebras, giraffes and other wildlife, as all surface waters are drying up and edible vegetation is becoming scarce. Worryingly, a sixth failed rainy season has already been predicted for March to May 2023.
Long rains down, short rains up
In a new paper we investigated changes in seasonal rainfall in the Horn of Africa over the past 30 years. We found the total rainfall within the “long rains” season is declining, perhaps related to the warming of a particular part of the Pacific Ocean. However, rainfall is increasing in the “short rains”. That’s largely due to a climate phenomenon known as the Indian Ocean Dipole, when a warmer-than-usual Indian Ocean produces higher rainfall in east Africa, similar to El Niño in the Pacific.
We then investigated what these rainfall trends mean for water stored below ground. Has it decreased in line with declining “long rains”, or risen due to the increasing “short rains”?

To do this we made use of a pair of satellites which orbit repeatedly and detect small changes in the Earth’s gravitational field that can be interpreted as changes in the mass of water storage. If there’s a significant increase in water storage underground, then the satellite will record a stronger gravity field at that location compared to the previous measurement, and vice versa. From this, the mass of water added or lost in that location can be determined.
Using these satellite-derived estimates, we found that water storage has been increasing in recent decades. The increase correlates with the increasing “short rains”, and has happened despite the “long rains” getting drier.
Given that the long rains deliver more seasonal rain than the short rains, we wanted to understand the paradoxical finding that underground water is increasing. A clue is given by examining how rainfall is converted into groundwater in drylands.
When rain is light and drizzly, much of the water that reaches the ground dampens the soil surface and soon evaporates back into the warm, dry atmosphere. To become groundwater, rainfall instead needs to be intense enough so that water will quickly infiltrate deep into the soil. This mostly happens when lots of rain falls at once and causes dry riverbeds to fill with water which can then leak into underground aquifers.

These most intense rainfall events are increasing in the “short rains”, in line with the overall increase in total rain in that season. And despite a decrease in overall rainfall in the “long rains”, intense rainfall has remained consistently high over time. This means that both rainy seasons have enough intense rainfall to increase the amount of water stored underground.
Finally, we demonstrated that the increasing water storage in this region is not connected to any rise in soil moisture near the surface. It therefore represents “banked” water that resides deep below ground and likely contributes to a growing regional groundwater aquifer in this region.
Groundwater can help people adapt to climate change
While early warning networks and humanitarian organisations focus on the urgent impacts of drought, our new research points to a silver lining that may support long-term climate adaptation. Those rising groundwater supplies we have identified may potentially be exploited to support people in rural areas whose food and water are increasingly insecure.
But there are some caveats. First, we have not assessed the depth of the available groundwater across the region, but we suggest that the water table is shallow enough to be affected by seasonal rainfall. This means it may also be shallow enough to support new bore holes to extract it. Second, we do not know anything about the quality of the stored groundwater and whether it can be deemed suitable for drinking. Finally, we do not know exactly what will happen if the most extreme droughts of the past few seasons continue and both long and short rains fail, causing intense rainfall to decrease too.
Nevertheless, our findings point to the need for extensive groundwater surveys across the Horn of Africa drylands to ascertain whether this increasing water resource may be viable enough to offset the devastating droughts. Groundwater could potentially irrigate fields and provide drinking water for humans and livestock, as part of a strategy to help this vulnerable region adapt to the effects of climate change.
