The pits left behind after mining can be made into lakes and the surroundings landscaped into gardens and parks.
Trees can be planted to protect the land from soil erosion.
Smaller mine pits can be filled and leveled with rocks and soil. The land can be treated to make it usable again for farming, housing and other activities.
The use of fertilisers and an irrigation system are necessary to make the land arable and more productive. The land can also be left fallow for a long period of time to allow the soil to regain its nutrients.

Is a cape made of land or water?
A cape is made of land. :)
Why has the land under forest not increased much since 1960-1961?
Land resources in India are primarily divided into agricultural land, forest land, land meant for pasture and grazing, and waste land. Waste land includes rocky, arid and desert areas, and land used for other non-agricultural purposes such as housing, roads and industry. According to the recent data, about 54% of the total land area is cultivable or fallow, 22.5% is covered by forests, and 3.45% is used for grazing. The rest is waste land, with traces of miscellaneous cultivation. The improper use of forest land has degraded the available land area, and has made conservation of forests difficult. Human activities such as deforestation, mining and quarrying have contributed to the slow growth rate of forests. Thus, land under forest has increased by only about 4% since 1960-61.

How much of Saudi Arabia is made up of arable land?
5 %
Saudia Arabia's land is made up of what?
Saudi Arabia is mostly desert with very little arable land.
Is Australia made up of all desert?
No. There is a great deal of arable land which is not desert. However, the great majority of the land mass of Australia is either arid or sem-arid, with little surface water. Some of the larger deserts are the Great Victoria Desert, the Gibson Desert, the Tanami Desert, the Great Sandy Desert, the Little Sandy Desert, Sturt Stony Desert, the Simpson Desert. That accounts for most of the west of the continent, and about 44% of the continent.
What is the term for an area of land made fertile by a source of fresh water in an otherwise arid region?
An oasis
How do you make derelict land into usable land again?
The pits left behind after mining can be made into lakes and the surroundings landscaped into gardens and parks. Trees can be planted to protect the land from soil erosion. Smaller mine pits can be filled and leveled with rocks and soil. The land can be treated to make it usable again for farming, housing and other activities. The use of fertilisers and an irrigation system are necessary to make the land arable and more productive. The land can also be left fallow for a long period of time to allow the soil to regain its nutrients.
What percentage of Australia is classified as arid or semi arid?
Sources differ as, according to the Australian Government's GeoScience website, Australia's land cover does change constantly due to weather and land use. Over a period of even one decade, figures will change. An estimated 44% percent, or over one-third of Australia is made up of sandy or stony arid and semi-arid desert, while another 37% is sparse grassland or scrub. The figures for arid and semi-arid are very different from those given in the source quoted below. Another source states the Arid and semi-arid zone constitute over 70% of Australia's land area (James, Landsberg & Morton, 1995) Source: James, C. D., Landsberg, J. & Morton, S. R.

What is arid soil made of?
sand
What geographical feature of northern France made it suited to trench warfare?
Northern France is mainly arable, agricultural land. The soil isn't rocky but easy to dig. The land is relatively flat so it was useful to dig trenches to protect against the enemy's bullets.
What is land used for crops or pasture?
By Perrault Jean-PaulLand suitable for farming is often referred to as "Arable Land". Generally most land is suitable for farming unless certain conditions exist that make it unsuitable. As such, it is better to ask what land is not suitable for farming. A good excerpt on Wikipedia on the subject follows:Land which is unsuitable for arable farming usually has at least one of the following deficiencies: no source of fresh water; too hot (desert); too cold (Arctic); too rocky; too mountainous; too salty; too rainy; too snowy; too polluted; or too nutrient poor. Clouds may block the sunlight plants need for photosynthesis, reducing productivity. Plants can starve without light. Starvation and nomadism often exists on marginally arable land. Non-arable land is sometimes called wasteland, badlands, worthless or no man's land.However, non-arable land can sometimes be converted into arable land. New arable land makes more food, and can reduce starvation. This outcome also makes a country more self-sufficient and politically independent, because food importation is reduced. Making non-arable land arable often involves digging new irrigation canals and new wells, aqueducts, desalination plants, planting trees for shade in the desert, hydroponics, fertilizer, nitrogen fertilizer, pesticides, reverse osmosis water processors, PET film insulation or other insulation against heat and cold, digging ditches and hills for protection against the wind, and greenhouses with internal light and heat for protection against the cold outside and to provide light in cloudy areas. This process is often extremely expensive.Some examples of infertile non-arable land being turned into fertile arable land are:* Aran Islands: This island off the west coast of Ireland, (not to be confused with the Isle of Arran in Scotland's Firth of Clyde), was unsuitable for arable farming because it was too rocky. The people covered the island with a shallow layer of seaweed and sand from the ocean. This made it arable. Today, crops are grown there.* Israel: Israel's land primarily consisted of desert until the construction of desalination plants along the country's coast. The desalination plants, which remove the salt from ocean water, have created a new source of water for farming, drinking, and washing.* Slash and burn agriculture uses nutrients in wood ash, but these expire within a few years.* Terra preta, fertile tropical soils created by adding charcoalSome examples of fertile arable land being turned into infertile land are:* Droughts like the 'dust bowl' of the Great Depression in the U.S. turned farmland into desert.* Rainforest Deforestation: The fertile tropical forests turn into infertile desert land. For example, Madagascar's central highland plateau has become virtually totally barren (about ten percent of the country), as a result of slash-and-burn deforestation, an element of shifting cultivation practiced by many natives.* Each year, arable land is lost to desertification and erosion from human industrial activities. Improper irrigation of farm land can wick the sodium, calcium, and magnesium from the soil and water to the surface. This process steadily concentrates salt in the root zone, decreasing productivity for crops that are not salt-tolerant.* Urban sprawl: In the United States, 8,900 km2 (2,200,000 acres) of land was added to urban areas between 1992 and 2003.
What kind of land covers most of Australia?
The answer to this question is presumably "desert". However, this is not strictly true. According to the Desert Knowledge Australia Fact Sheet, 70% of Australia is classified as desert or semi-arid. However, much of this land is used for grazing beef cattle and sheep, so it is not desert in the truest sense. Other figures state an estimated 44% percent, or over one-third of Australia is made up of sandy or stony arid desert, while another 37% is semi-arid grassland or scrub.
How did the geography of the nile lead to the growth of a civilization there?
Civilization grew there because they had fresh supply of water which made the land arable and they were protected. In the north they had the Nile Delta. In the south they had the two cataracts which made it impossible for boats to get them. Finally to the east and west they had large deserts.
