1
Effect of Land Clearance or Land "Reclamation" Infrastructural project: build a air station WYS
3
Effect on environment Deforestation Deforestation increase global warming due to the less trees can absorbed carbon dioxide increase global warming due to the less trees can absorbed carbon dioxide decrease the bio diversity of plant decrease the bio diversity of plant the disappearance of indigenous groups of plant the disappearance of indigenous groups of plant
4
plants can sustain animals through provision of habitat and a food source, so food chain is blocked. plants can sustain animals through provision of habitat and a food source, so food chain is blocked. soil sustains plants and which then act as water capture system soil sustains plants and which then act as water capture system
5
Exposed soils Exposed soils soil erosion as the plant can not cover conserved soil soil erosion as the plant can not cover conserved soil declining fertility and desertification (minerals/metal loss e.g. gold, Mg ) declining fertility and desertification (minerals/metal loss e.g. gold, Mg )
6
degrade the water quality of downstream communities degrade the water quality of downstream communities contribute to flooding and silting of rivers and dams contribute to flooding and silting of rivers and dams Landlocked harbour Landlocked harbour
7
reclamation reclamation erosion on cleared land increases sediment loads erosion on cleared land increases sediment loads land clearance often extends to the coastal regions and into the sea itself land clearance often extends to the coastal regions and into the sea itself
8
clarity of the water (turbidity) clarity of the water (turbidity) nature of sediments (for example, changes from sandy to muddy) nature of sediments (for example, changes from sandy to muddy) decreases in water depth decreases in water depth affect the distribution of plants, animals and their habitats affect the distribution of plants, animals and their habitats
9
Pollution Pollution water pollution (make water turbidity, release of heavy metal, organic solvents) water pollution (make water turbidity, release of heavy metal, organic solvents) land pollution (e.g. litter) land pollution (e.g. litter) air pollution (exhaust air from machine) air pollution (exhaust air from machine)
10
Effect on wildlife Loss of habitat (e.g. forest, coral) Loss of habitat (e.g. forest, coral) lead to the extinction of species lead to the extinction of species the disappearance of indigenous groups the disappearance of indigenous groups
11
Decrease bio diversity Decrease bio diversity Loss of food sources( food chain is blocked----no producer) Loss of food sources( food chain is blocked----no producer)
12
Effect on human provide a new space for human development provide a new space for human development Increase economic intake Increase economic intake Provide more job opportunities Provide more job opportunities
13
Increase in human populations in tropical regions Increase in human populations in tropical regions Increase international exchange Increase international exchange
