CHAP 10.1 DEFORESTATION Flashcards
Land spanning more than 0.5 hectares with three taller than 5m and a canopy cover of more than 10% or trees able to reach the thresholds in situ
Complex ecological systems and natural resources in which trees are the dominant life form
Is a large area dominated by trees and other vegetation characterized by a complex ecosystem that includes various species of plants animals fungi and microorganisms
FOREST
It is vital for both the environment and human well-being
their health directly impacts our quality of life and the planets future
FOREST
It is clearing or thinning the forest by humans.
It represents one of the largest issues in global land and use. Estimates of _____________ traditionally are based on the area of forest cleared for human use including removal of the trees for wood products and crop plants.
DEFORESTATION
It is the clearing or removing forest or trees from a land area, resulting in the permanent or long term conversion of forested land to non forest uses
DEFORESTATION
Causes
Agricultural expansion
Logging
Infrastructure development
Mining
Urbanization
Cattle ranching
Fire
Climate change
Population growth
Economic development
Plantation forestry
Agricultural expansion
Commercial agriculture
Livestock farming
Subsistence farming
AGRICULTURAL EXPANSION
Large scale farming for cash crops (soy, palm oil)
COMMERCIAL AGRICULTURE
AGRICULTURAL EXPANSION
Cattle ranching, particularly in tropical regions
LIVESTOCK FARMING
AGRICULTURAL EXPANSION

Consequences of deforestation
Loss of biodiversity
climate change
Soil erosion
Disruption of water cycle
Impact on indigenous communities
Increase natural disasters
Decline in ecosystem services
Economic consequences
Health impacts
Altered land use
Deforestation leads to habitat destruction threatening countless species of plants and animals many of which may have become extinct
LOSS OF BIODIVERSITY
Trees help anchor the soil the removal can lead to increase erosion loss of fertile capsule and degradation of land
SOIL EROSION
Forest plays a crucial role in maintaining the water cycle. Deforestation can alter rainfall patterns reduce groundwater recharge and increase the risk of floods and droughts
WATER CYCLE DESTRUCTION
Trees absorb carbon dioxide when they are cut down the stored carbon is released back into the atmosphere contributing to global warming
INCREASE GREENHOUSE GAS EMISSION
Deforestation can lead to changes in local and global climate patterns affecting weather systems and increasing the frequency of extreme weather events
ALTERED CLIMATE PATTERNS
Money indigenous communities depend on the forest for your livelihoods and cultural practices. Deforestation can lead to displacement and loss of traditional way of life
DISPLACEMENT OF INDIGENOUS PEOPLE
The loss of forest can impact local agriculture on fisheries leading to food shortages and reduce access to clean water
FOOD AND WATER SECURITY
Will deforestation may provide short term economic gains it can lead to a long term economic instability due to the loss of ecosystem services and resources
ECONOMIC CONSEQUENCES
Deforestation can lead to increased air pollution as trees filter pollutants and produce oxygen. The burning of forest also release harmful smoke and particulates
AIR QUALITY DETERIORATION
Deforestation can alter ecosystem and increase human wildlife interactions potentially leading to the spread of zoonotic diseases (diseases transmitted from animals to humans)
SPREAD OF DISEASES
Forest provides numerous ecosystem services including timber, non timber products and medical resources.
DECREASE NATURAL RESOURCES
Forests help regulate local climate and temperatures. Their loss can lead to more extreme temperature fluctuations
REDUCE CLIMATE REGULATION
Without trees to absorb rainfall and stabilize the soil areas become more susceptible to flooding and landslides particularly inhaling or mountainous region
FLOODING AND LANDSLIDES
Deforestation often benefits where corporations of the expense of local communities exacerbating social and economic qualities
MARGINALIZATION OF LOCAL COMMUNITIES
Deforestation contributes to climate change by releasing carbon dioxide stored in trees accounting for about ___________ of global emissions
10-15%
Planting trees in areas where forest have been cut down to restore ecosystem and enhanced biodiversity
REFORESTATION
Planting trees in previous non-forested areas to expand forest cover and increase carbon sequestration
AFFORESTATION
Sustainable forest management
SELECTIVE LOGGING
CERTIFICATION SCHEMES
Combining agricultural crops with trees to enhance biodiversity improve soil health and provide additional income through timber and non timber forest products
AGROFORESTRY
INTEGRATING TREES WITH AGRICULTURE
Planting crops within rows of trees
ALLEY CROPPING
Operations grow crops under a forest canopy to provide ideal shade
FOREST FARMING
Combine trees with livestock and forage
SILVOPASTURE
Promote sustainable forest management
