Overgrazing from livestock
Unsustainable resource extraction
Rapid urbanization
All of the above
Answer explanation
Land degradation is among the world’s most pressing environmental crises. It refers to the reduction or loss of ecosystem productivity and has several interrelated causes. For example, unsustainable agriculture and urbanization reduce productive land area, leading to overgrazing from livestock and impeding productive ecosystems. Reforming agricultural subsidies to work with nature and not against, and ensuring more equitable access to land are examples of effective policymaking. Indigenous and traditional knowledge can also inform sustainable land management.

What percentage of the Earth's population suffers from the impacts of land degradation?
20%
40%
60%
Answer explanation
Land degradation affects approximately 3.2 billion people, or 40 per cent of the world’s population. It threatens well-being and disproportionately harms those who are least equipped to cope such as rural communities, farmers and the poor. They suffer from food shortages, failing harvests, volatile food prices, and climate impacts caused by the release of carbon from degrading land. By 2030, land degradation and desertification could force 135 million people to migrate, creating social and economic inequalities.

What is Earth's most biodiverse habitat?
Coral reefs
Deserts
Forest
Soil
Answer explanation
Almost 60 per cent of all species live in soil. These species include microbial organisms, medicinal fungi and mammals. Soil also stores significant carbon emissions and produces 95 per cent of our food. One spoonful of healthy soil includes more living organisms than there are people on the planet. Yet soil erosion affects some 20 per cent of all farmlands and is rising due to deforestation and cropland expansion.

What can you do to tackle land degradation?
Plant trees everywhere
Change food choices and waste collecting habits
Recycle plastics
All of the above
Answer explanation
The global food system is the biggest driver of biodiversity loss and significantly affects land degradation. Including more pulses in your diet and making other sustainable food choices can actually help repair soil. You can also prevent land degradation by collecting kitchen waste to compost. Remember, tree-planting doesn’t work everywhere and can harm areas like grasslands. Plastic pollution is a threat to soil and must be addressed, but it is not the biggest driver of land loss

The Sahara and other hot deserts are dead and have no biodiversity value.
True
False
Answer explanation
As carbon sinks, deserts play a vital role in climate regulation and are home to billions of people. The Sahara hosts hundreds of plant, mammalian, reptile and avian species, as well as arthropods like spiders and scorpions. Desertification primarily refers to land degradation caused by human activities. This threatens essential functions and biodiversity in other ecosystems. While humanity must prevent desertification, it must also protect and rewild existing natural deserts.

Drought affects 55 million people a year, and is not as big of a deal as land degradation and desertification, which affect billions of people.
True
False
Answer explanation
Drought, land degradation and desertification are interrelated crises that require unified action from all stakeholders. Drought, which is primarily caused by the climate crisis, is the most serious hazard to livestock and crops globally. Some 700 million people are at risk of being displaced due to drought by 2030. It has widespread implications on human well-being, ecosystem health and economic prosperity – even for those who don’t live in drought-prone areas.
