How much land is degraded in the world?
Globally, about 25 percent of the total land area has been degraded. When land is degraded, soil carbon and nitrous oxide is released into the atmosphere, making land degradation one of the most important contributors to climate change.
Are there more trees on Earth now than 100 years ago?
The numbers are in. In the United States, which contains 8 percent of the world’s forests, there are more trees than there were 100 years ago. According to the Food and Agriculture Organization (FAO), “Forest growth nationally has exceeded harvest since the 1940s.
How many trees were there 100 years ago?
How many trees were there 100 years ago? About 70 million trees. The early 1920’s defined an exponential growth in the timber industry due to the developments that were happening in the construction and recreation industry. This made it one of the key drivers for deforestation in the US.
How much of the world’s arable land is used for farming?
One-third of global arable land is used to grow feed. – globalagriculture.org. [Of the 51 million km squared area of habitable land used as agricultural land in the world, 40 million km squared is used for livestock/meat and dairy, and 11 million km squared is used for crops excluding feed.
How much of the world’s land is cropped?
At present some 11 percent (1.5 billion ha) of the globe’s land surface (13.4 billion ha) is used in crop production (arable land and land under permanent crops). This area represents slightly over a third (36 percent) of the land estimated to be to some degree suitable for crop production.
What is arable land used for?
Some arable land is used to grow crops (such as corn, barley, oats, soy, and so on) that become feed for livestock (instead of going straight to human consumption), which technically means it’s part of the total land being used for livestock production.
What are the two types of agricultural land?
Different Types Of Agricultural Land. The two main types of agricultural land are: – Pasture/grazing/range land (also referred to as meadows) Used for livestock rearing and animal product production. – Arable/cropland (also referred to as cultivated land) Used for crop production.

Why is land important for agriculture?
Land – a notion which broadly includes climate, topography, vegetation, soils and other natural resources – is the basis for agriculture, and the interaction between these components is vital for determining the productivity and sustainability of agro-ecosystems. Especially in the face of climate change and variability, selecting the right land uses for given biophysical and socio-economic conditions is essential for minimizing land degradation, rehabilitating degraded land, ensuring the sustainable use of land resources, and maximizing resilience.
Which region has the most land area for irrigation?

Which countries are affected by deforestation?
Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname, and French Guiana make up the Amazon basin which is where the Amazon rainforest grows. Brazil, Bolivia, and Peru have been hit the hardest by deforestation due to excessive logging, agriculture, and cattle production.
What are the animals that are being displaced by deforestation?
Sumatran rainforests, which are home to most of the world’s orangutans, are being ravaged for palm oil and paper products. Rhinos, tigers, and gorillas are being displaced by deforestation and illegally poached in Asia and Africa.
How does deforestation affect soil?
Deforestation removes vegetation, which anchors soil in place. Without enough trees, soil is vulnerable to erosion and nutrient loss. The absence of roots causes topsoil to easily wash or blow away, leading to decreased soil quality and increased landslides. It’s estimated that a third of the world’s arable land has been lost to soil erosion and degradation since 1960. Once land is cleared and roots are ripped away, cash crops like coffee and soy are planted which can make erosion worse, since their roots cannot anchor into the soil like those of a tree.
What are the causes of crop extinction?
Deforestation is a leading cause of climate change, which is a leading cause of crop extinction. If our forests continue to vanish and release greenhouse gases into the air, crops like coffee, tea, avocados, chocolate, and bananas could be largely lost in our lifetime.
What percentage of the Amazon rainforest has been cleared?
At least 20 percent of the Amazon has already been cleared and around 80 percent of that land has been used for cattle. According to environmental researcher Nicholas Carter, “Animal agriculture is the leading cause in the reduction of biodiversity, which is mostly from deforestation.
How much land is ideal for farming?
Just 17% of American land is ideal for farming. We don’t have that much to lose! The amount of the best land lost is about equal to California’s entire Central Valley.
What is the most important factor that caused the loss of farmland?
It probably comes as no surprise that the expansion of cities and suburbs are responsible for most of the loss in farmland. But 41% of the lost acres actually came from development in rural areas.
What does it mean when a farmland rating is 0.65?
If farmland has a rating above that – say, 0.65 – that makes it great farmland. Below that, and it’s subpar. Farmland with a high rating is being lost disproportionately quickly, which means suboptimal farmland will have to be used. And suboptimal farmland requires more water, more transportation, more energy, more fertilizers, …
Where is 10% of the world’s arable acres?
10% of the world’s arable acres lie within the United States.
Why is farmland being lost?
And, of course, some of the farmland being lost is for so-called “specialty” crops, like fruits and vegetables. But there are other reasons as well. Development on farmland can have negative effects, removing land that animals use as a habitat. Well-operated farms care for the soil, air, and water, and produce viable ecosystems.
Why is farmland less important than food?
This is concerning for a variety of reasons. The obvious one is that farmland produces food, so less farmland means the price of food may rise . The majority of American farmland is devoted to commodity crops – soy, corn, wheat – and many of the uses of those crops are not for direct eating.
When was agricultural land converted to urban land?
This image, courtesy of American Farmland Trust, shows the conversion of agricultural land to urban and low-density residential development between 1992 and 2012.
How does land clearance affect the ecosystem?
Land clearance greatly impacts on the health of rivers and coastal ecosystems. It increases erosion and the runoff of sediment, nutrients and other pollutants into coastal waters, causing damage to coral reefs and other marine ecosystems such as se agrass beds . Increased nutrients in rivers and streams can cause outbreaks of toxic algae.
How does land clearing affect animals?
Land clearing kills animals directly. Millions dies each year during land clearing operations. Ten million are being lost each year in NSW alone. This occurs when they’re harmed during land clearance operations, lose their shelter and are exposed to the elements and feral predators, and because they lose their food sources.
How are native birds declining?
Native birds are declining precipitously . [ 3] Populations of Australian terrestrial birds have declined by 50% since 1990. [ 4] Even once-common birds are now in trouble in many areas. [ 5] Many threats are responsible, but habitat loss through land clearance and subsequent decline in the condition of isolated remnant habitat is high among them.
How does clearing a habitat affect the environment?
Clearing removes habitats, leading to the direct loss of millions of native animals and plants every year. Australia’s mammal species have suffered an extraordinary rate of extinction over the last 200 years. [ 2]
Is Australia a deforestation hotspot?
Extreme rates of land clearing placed Australia in the top 10 land clearing nations in the world in 2017 and a WWF report has Australia as the only developed nation among the world’s deforestation hotspots.
How much of Australia’s rainforest has been cleared?
About 50% of Australia’s rainforests have been cleared and the proportion of Australia covered by forest or woodland has been reduced by more than a third [ 1]
Is there clearing of native vegetation?
We’re still clearing much more native vegetation than is being replanted or regenerating naturally. Irreplaceable, high-quality habitat is being cleared, and any natural regrowth, over the short term will be of much lower diversity and lack important structural elements such as hollow trees and ground timber.
How many trees are cut down in a year?
Tree density in primary forests varies from 50,000-100,000 trees per square km, so the math would put this number at 3.5 billion to 7 billion trees cut down each year.
What are the causes of forest loss?
According to IntactForests.org, major categories contributing to forest loss include: Timber harvesting (37%), agricultural expansion (28%), wildfire (21%), construction of roads for resource mining and extraction, pipelines, and power lines (12%) and expansion of transportation networks via roads (2%).
What is the loss of biodiversity?
Loss of Biodiversity: Forests are the only liveable habitat for a variety of species around the globe — many of which have not even have been discovered. For example, just one area of forest — Indonesia’s rainforests — covers just 1 percent of the Earth’s land area, but contains 10 percent of the world’s known plant species, …
What is the biggest threat to forests?
The biggest threat to forests today is industrial agriculture production of commodities like Conflict Palm Oil, fabric, …
How do forests help the environment?
They serve as carbon sinks, absorbing carbon released into the atmosphere from fossil fuels. Conversely, when forests are cut down, they release that carbon back into the air. Twenty percent of global greenhouse gas emissions come from felling the world’s forests.
How much land does livestock take up?
Livestock takes up nearly 80% of global agricultural land, yet produces less than 20% of the world’s supply of calories (as shown in the visualization). This means that what we eat is more important than how much we eat in determining the amount of land required to produce our food.
What is the dominant contributor to dietary land requirements?
The second consideration to note is that, as we have explored above, the dominant contributor to dietary land requirements is livestock rather than crops. Although productivity in livestock farming has increased over the last 50 years, this change has been more modest than gains in crops yields; the meat yield per cattle has increased by approximately one-third since 1961, which is significantly lower than improvements in cereal yields, which have grown more than five-fold across many countries. This increase in animal productivity has also been strongly offset by global meat production which has more than quadrupled over the same period.
How can we make the highest impact change to our diets?
How do we do this? Arguably the highest-impact change we can make to our diets is to reduce our meat intake—particularly that of beef or mutton. In the chart below we see the relative land requirements per gram of protein across a range of food commodities. 4
What is the relationship between beef consumption and land use?
Here we see a very strong relationship: the more beef we eat, the higher our land use requirement. Such strong correlations are not seen for other meat types, such as pig meat (where there is no clear relationship between intake and land requirements). The key outlier on this plot is New Zealand—its population also has a strong preference for lamb/mutton, which requires a similar amount of land per kilogram of meat as beef does.
Does food affect land use?
Alexander et al. (2016) highlight that the types of foods we eat have a much stronger impact on land use than the quantity alone. The land requirements of different diets tend to be most strongly correlated to a country’s level of per capita meat consumption—and most notably that of ruminants (beef and mutton). 2,3
Is there a difference in land requirements between countries?
Nonetheless, there are still large differences in dietary land requirements between countries of a similar income-level. Why, for example, is the requirement for a New Zealander more than double that of a UK citizen, despite them having similar levels of prosperity?
Why is there a trade-off between environmental impact and nutrition?
The implication is that there is an important trade-off between environmental impact and nutrition: for a variety of ecological reasons, including biodiversity and climatic change, we want to reduce our agricultural land pressures; but we also want a healthy and adequately nourished population.
What percentage of land clearing is done in Queensland?
A 2017 government report states that 93% of the land clearing (deforestation) in Queensland (the large north-eastern state of Australia) is being done to make pasture for livestock; for eventual human consumption.
How does clearing land affect climate?
Regards land clearing and reduced rainfall, from a 2016 report: “ Stopping land clearing and replanting trees could help keep Australia cool in a warmer future … Land clearing releases greenhouse gases into the atmosphere, but the effect of land clearing on climate goes well beyond carbon emissions. It causes warming locally, regionally and even globally, and it changes rainfall by altering the circulation of heat and moisture …
What is happening in the oceans, seas and rivers?
Excerpts from articles about the marine ecosystem collapse that is happening now in oceans, seas & rivers due to over-fishing and the toxic pollution in waterways from land-based animal agriculture meat-farming; worsening climate change; threatening the entire food chain.
Where are the oldest trees being cut down?
some of Australia’s most majestic and oldest trees are being cut down for timber by a state-owned company in Victoria, which has even less left to lose than NSW. And Tasmania has just signed up to allow more logging in its national parks…”. …
What is the main cause of clearing?
The main cause of clearing is for pasture… . ”  A definition of pasture is “land covered with grass and other low plants suitable for grazing animals, especially cattle or sheep.”.  In other words the main cause of deforestation in Australia was to benefit the profits of the animal agriculture livestock industries.
Is destruction of nature dangerous?
