There Are Various Impacts Of Desertification, Deforestation And Climate Change On Fragile Environments
Bayani Gaba-gaba
Degraded land, cleared forest and a warming atmosphere are not abstract environmental problems. They show up as a failed harvest, a family that moves to the city, a fishing village that loses its reef and a coastline that has to be defended or abandoned. This lesson is about consequences, and about sorting them clearly.
You will work through the social, economic and environmental impacts of desertification and of deforestation, then examine what climate change is doing to fragile environments and to the people who depend on them. The skill being built is classification: putting each impact under the right heading, and showing how one impact triggers the next.
Manufura
- Social, economic and environmental impacts of desertification (reduced agricultural output, malnutrition, famine, migration)
- Social, economic and environmental impacts of deforestation (loss of biodiversity, contribution to climate change, economic development and increased soil erosion)
- Negative effects that climate change is having on fragile environments and people (rising sea levels, more hazards, ecosystem changes, reduced employment opportunities, changing settlement patterns, health and wellbeing challenges, including food supply)
