Population GrowthPopulation Growth Around Lake Victoria 1960 - 2015
• The population growth around 100 km buffer zone of the Lake Victoria
• Population growth around Lake Victoria, East Africa, is the highest in Africa
These images show deforestation rate in the area, believed to be one of the highest in the world
• 1988: Shows destruction of small forest fragments
• 2002: The lighter green strip bisecting the images is the result of extensive deforestation and intensive cultivation
Tai National Park, Côte d’Ivoire – site of world’s highest deforestationdeforestation rate
DeforestationDeforestation in Itampolo, Madagascar
These images show the changes in narrow coastal plain
• 1973: Shows heavily forested area home to unique and rare plant and animal species
• 2001: Burning of forest to clear land for dry rice cultivation, has led to disappearance of forest area (seen as tan)
DeforestationDeforestation Around Lake Nakuru, Kenya
These images show the land cover degradation in the lake’s catchment
• 1973: The area that hosts the world’s largest concentration of flamingos
• 2000: Excision of forest in the Eastern Mau Forest Reserve (white lines) will most likely lead to disappearance of upper catchment forest cover
DesertificationDesertification in Ravene, Senegal
Images show impact of drought and over-grazing on the woody vegetation
• 1965: Ancient valleys cutting through gravelly plateaus, with extensive bushland vegetation
• 1999: desertification spreads extensively along the shallow valley slopes
DesertificationDesertification leaves the land barren and unable to support agriculture
