Long term impacts on the carbon cycle and management strategies Flashcards
Name some management stratagies
Wetland restoration
Afforestation
Sustainable agriculture practices
Control greenhouse emissions
What are the threats to wetlands
Population growth
Economic development
Urbanisation
What do Ramsar sites do
Work towards the wise use of all their wetlands
Cooperate internationally on trans boundary wetlands
Restoration focus
Raising local water tables
Reconnecting wetlands on floodplains to rivers
Reclaimed marshland can be restored by allowing the sea defences to breach
What are the threats to forests
Logging
Farming
Mining
What is afforestation
Involves planting trees in deforested areas
Can reduce CO2 levels in the medium and long term and combat GCC
UN Reducing Emissions from Deforested and Forest Degredation
Incentives developing countries to conserve their rainforest by placing a monetary value on forest conservation
Afforestation in China
Aim to afforest 400, 000km2 by 2050
Non-native, fast growing species such as popular and birch
Combats desertification and land degradation in the semi-arid expanses of northern china
How do agricultural practices threaten the carbon cycle
Over cultivation, overgrazing and excessive intensification
This has led to soil erosion and the release of huge quantities of carbon
Livestock production
Padi fields
Management - Land and crop management
Zero tillage Polyculture Crop residues Avoiding using heavy machinery Contour ploughing and terracing
Management - manure management
Control way manure decomposes to reduce amount of methane produced
Capturing methane to use as a renewable source
International agreements to reduce carbon emissions
GCC affects all countries
Solving the problem requires international cooperation
Kyoto protocol 1997
Reduction in signed up countries emissions
USA refused to ratify the agreement
Paris agreement
Reduce global CO2 emissions below 60% of 2010 levels by 2050
Cap and trade
Alternative, international market- based approach to limit CO2 emissions
Can purchase credits for those who need a bigger quota of other companies
