Sustainable Development Challenges
• Rapid melting of glacier and loss of snow cover
• Increased frequency and magnitude of natural disasters
• Changes in vegetation cover/ forest resources
• Species migration and biodiversity loss
• Transboundary air pollution and black carbon
• Population dynamics and migration
• Many other socio-ecological pressures…
