Increase in animal numbers

Physical Factors or Human Factors

Terraces collapse

How do these create erosion?

Melting snow

Unstable soil

Heavy Rain

Steep Slopes

Population Increase

Tourists & Trekkers Trees for firewood

Increase in animal numbers

Soils need to be stabilised - Terraces

Deforestation

Overgrazing

Terraces under threat and some collapse

Solutions
