Dried rivers, denuded forests, dead livestock, malnourished children, disempowered populations—these are just some of the harrowing images the media routinely depict about Africa.

Indeed, land degradation, desertification, and drought are causes for concern. Yet we know that the continent’s,,, and rivers represent the promise of restoration.

Peatlands, for example, can store extensive amounts of carbon for centuries if protected. Grasslands, often viewed us unproductive wastelands, are important storehouses for carbon and a livelihood resource for pastoral communities, useful for grazing of wild and domestic species.

Forests are important carbon sinks too. If degraded and lost, they can also become huge greenhouse emitters.

Land degradation is a global issue

Land quality is in decline worldwide. Global assessments show that, putting half of the world’s population at risk.

Degraded lands and soils lose their ability to support animal and plant life. They cannot provide water, food, or protect against the impacts of droughts, floods, fires, or even diseases like COVID-19.

People are chiefly responsible for this predicament. Humans have converted or transformed 70 per cent of the world’s land from its natural state, to “managed lands.” Animal grazing represents the single largest, followed by managed forestland and cropland.

InEurope,25 per cent, an equivalent of 120,000km2, of peatlands are reported degraded, and, risking desertification for 25 per cent of southern Europe.

Soil quality in theUnited Stateshas degenerated so significantly that farmers there spend anto maintain world dominance as the largest producers of maize and other crops.

Incentral Asia, extraction of water for agricultural purposes, has reduced the Aral Sea from the fourth largest lake in the worlddevastating livelihoods and economies in Kazakhstan and Uzbekistan. A similar future may be facing Lake Chad inWest Africa.

Declining forests

Forests across the planet. Most of those in dire state are in, such as the Amazon in Brazil and Latin America; in Indonesia and elsewhere in Southeast Asia; and in Congo in Central Africa.

Wildfires and loggingtree loss in the boreal and temperate forests ofRussiaand North America. Co-opted for agriculture,,which cover 24 per cent of the earth’s surface, are at serious risk.

Climatologists refer to land degradation occurring in drylands as desertification and point to human activity—overexploiting of soil and water resources—and climate change as culprits.

Drought often accompanies desertification, affecting more than 55 million people worldwide every year, especially the poor in low-income countries.

Desertification, land degradation, and drought affect sub-Saharan Africa more than any single region on earth. Asia is a close second. These regions, most of them poor rural communities, made up of small-scale farmers, women, youth, indigenous peoples, and other at-risk groups, are under immense pressure to feed themselves.

“By supporting Africa’s initiatives, such as its commitments to reversing land degradation, abating desertification, bending the curve on greenhouse gas emissions, and halting the extinction of wild species, the world also stands to benefit”

Reason for hope

Under- on Biodiversity, Climate Change and Desertification—and other voluntary initiatives, the world agreed, through pledges and commitments, to.

山member states have also declared 2021-2030 the. This is trigging a global movement and fuelling momentum for restoration and sustainable land management.

Sub-Saharan African countries are responsible for almost half of global restoration commitments and pledges. Many of them have made commitments under the Land Degradation Neutrality framework and.

African countries are focused on protecting and restoring natural areas and on managing and rehabilitating lands that have been converted largely for agriculture and forestry. Africa also promised tothrough the Great Green Wall (GGW) initiative—a bold objective, given the magnitude of the challenge of greening over 100 million hectares of desert and degraded land.

There are officially 11 African countries participating in GGW. So farare said to have contributed the most to GGW, largely through tree planting/reforestation, soil and water conservation, and farmer-managed natural regeneration.

Ironically, Africa holds the best solutions for moving the world towards a secure climate-resilient future but faces the toughest challenges. The continent has theyoungest population, the largest amount ofarable land, and thegreatest potential for restoration, and it alreadyhosts a quarter of the global stock of wildlife populations.

Yet, Africa houses the poorest people who are most vulnerable to climate and environmental stress. It also lacks the political muscle to secure enough financing for needed restoration and adaptation measures.

Estimates, for example, show it will take between $36 billion and $43 billion to restore the Sahel, which is far more money than the

estimates that fulfilling current global restoration commitments will require $1.6 trillion over 10 years. A 2015 study of 42 African countries showed thaton 105 million hectares of croplands, between 2016 and 2030, could yield as much as $62.4 billion per year. Globally, researchers estimate potential economic returns as high as—much more than it will cost.

In the global battle against climate change and biodiversity loss, Africa’s success is crucial. By supporting Africa’s initiatives, such as its commitments to reversing land degradation, abating desertification, bending the curve on greenhouse gas emissions, and halting the extinction of wild species, the world also stands to benefit.
