90% of the world population occupied only 30% of land area
remaining 70% of the land area is populated or unhabited
Methods of soil conservation
Mulching
Contour barrier
Rock dam
Terrace farming
Intercropping
Countour plugging
Shelter belt
Mulching
Mulching involves covering the soil with organic or inorganic materials to retain moisture, suppress weeds, regulate temperature, and improve soil health.
Terrace farming
Terrace farming is an agricultural method where flat areas, or “terraces,” are created on slopes to prevent soil erosion and manage water flow, making hilly land suitable for farming.
Intercropping
Intercropping is the practice of growing two or more crops together on the same piece of land to improve yield, reduce pests, and maximize resource use.
Contour ploughing
Flowing parallel to the counters of the hill to form natural barrier for water to flow down the slope
Shelter belt
The coastal and dry reason region rows of trees are planted check the wind movement to protect soil cover
Contour barriers
Stonee grass soil are used to build barriers along the contour
Trenches are made in front of the barrier to collect water
Rock dam
Rocks are piled up to slow down the flow of water
This prevents gullies and further soil loss
Factor affecting soil formation
Climate
time
flora fauna and microorganism
relief
parent rock
CITES
CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement between governments aimed at ensuring that international trade in wild animals and plants does not threaten their survival.
