Land is used for agriculture.
Water is used for domestic and commercial purposes.
Minerals are mined industrial, domestic and other purposes.
Trees and other plants are used to make lumber, paper, medicine and other by-products.
Wind and sunlight can be harnessed to generate electricity
Renewable resources are resources that can be recycled, resupplied or replaced after it has been used.
These include: land, plants, animals and water.
Non-renewable resources are resources that cannot be replaced or resupplied after they have been used.
These include: bauxite, petroleum, diamond and other minerals.
LAND AS A RESOURCE
Land is a fundamental resource and its use is many and varied. Land is often used for:
Building houses, schools, hospitals etc
Building industrial complexes
Misuse of land
Bad mining practices: mining often results in a lot of trees and top soil being removed. This can harmful to ecosystems especially when the trees are not replanted. Many times the land deteriorates as soil erosion takes place.
Land mismanagement: an example of this is land that is fertile and could be used for agricultural purposes instead get used for constructing houses, factories and other buildings.
Bad farming practices: some farmers practice plant the same crop on the same plot of land repeatedly. This results in the soil losing particular nutrients making it infertile. When farmers allow their herds to graze on a plot of land for a long time it leads to the depletion of plant life.
Without vegetation the soil becomes exposed thus leading to soil erosion. Soil erosion also happens when farmers plough hillsides as this practice exposes topsoil and when it rains the soil gets washed down the hill.
Measures for land preservation
In order to harness the resources from land some amount of damage and depletion has to take place. Land is however a renewable resource and with proper management the damage can be minimized or reversed.
Mining for minerals
Land is often mined to harness minerals such as aluminum, silver, gold and copper. These resources are used in many areas of manufacturing and wealth creation. Lands that are mined can be replenished by replanting trees after mining and quarrying is done.
The replanting of trees after the land has been cleared by logging operations.
Good farming practices
The use of humus and other fertilizers can be used to restore nutrients in the soil
Crop rotation is having different plots of land that are used to plant different crops in a cycled manner. This way you do not end up planting the same crop on the same plot of land repeatedly. It helps to prevent the soil becoming infertile.
Land for animal grazing should be divided up so that while the animals are grazing on one plot of land it allows vegetation enough time to grow back on the others.
Hillside cultivation should be done along contours. The step like structuring helps to prevent the soil from being washed down hill.
