Land Management
definition of the issue - what is it
Land management is the process of managing the use and development of land resources. Over the past few two centuries of exploitation on our land resources, has taken a heavy toll on our soils.
What are the causes of this issue? e.g land degradation, salinity and overgrazing
Firstly, land degradation is any change in the land that reduces its existing or potential productivity. It commonly occurs wherever the natural balance in the landscape is changed by human activity, through misuse or overuse. This is the result of land when using it beyond its capabilities. As we know, soil is a natural resource vital to the well-being of all Australians. It provides us with the food we eat and it supports one of our most important industries, agriculture. One of the causes of land degradation includes water erosion, the most widespread type of land degradation affecting Australia.
impact of this issue - how does this issue impact on the environment
Water erosion involves the removal of soil particles by water erosion, losing great amounts of soil where the vegetation cover is thinnest. Plant roods bind the soil, while leaves protect it from the impact of heavy rain whilst layers of humus (leaf matter) helps to absorb rainfall and reduce runoff of soil into small rivulets. (small stream.) Any sort of slope will make water erosion more severe, as water attains more force thus dislodging plants and more soil. If the water is evenly seething and eroding the soil, this is known as “sheet erosion”The soil eroded will then flow into channels/rivulets to then consequently form furrows or rills. (rill erosion) It will deposit itself to the bottom of a valley, increasing it’s clog channels and turbidity (muddiness). In the end, these eroded materials enter the sea.
strategies by individuals groups and governments minimizing the length of time that soil is left bare, particularly in areas where strong winds and drought occur
