  9. How do these create erosion? Soils need to be stabilised - Terraces Steep Slopes Unstable soil Heavy Rain Terraces under threat and some collapse Melting snow Tourists & Trekkers Trees for firewood Deforestation Increase in animal numbers Overgrazing Population Increase

  10. Solutions • Tree Planting Programmes • Alternative fuel sources (Yak dung!) • Fenced areas • Small dams • Government agencies • Self help schemes
