  • Nepal - Himalayas Problems
    • Poverty and population growth
      • rapid population and chronic poverty place huge pressure on Nepals natural env. and ecosystems and are the main drivers of environmental change.
    • Deforestation
      • 87% of Nepals mountain population depends on agriculture - 40% live below poverty line
      • forests are disappearing at a rate of 3% a year.
      • Overgrazing by sheep, cattle and goats, fuelled by population growth has speeded up deforestation
      • inncreasing demand for firewood, fodder and timber.
    • Tourism
      • Has increased inequality between those engaged in tourism and those who are excluded
      • 25,000 trekkers a year - imposed pressure on mountain ecosystems. Use of fuel wood is forbidden although this rule gets broken
      • Human waste - poses threat to env. polluting streams & rivers. Most waste left is non- biodegradabel
      • Trail erosion - Many heavily used tourist trails are deeply gullied. Trekkers often avoid eroded trails, trampling adjacent vegetationa dn causing further damage
        • Loss of habitat and forces change in species composition
