1 The Interaction between Climate Change
Vegetation A Review
2INTRODUCTION
Climate Change
Vegetation
3Description of Climate Change
The Global Climate Change Occurring due to
the Accumulated GHGs in the Atmosphere
4Descriptionof Climate Change
- The Origin of GHGs is Anthropogenic
Increasing Greenhouse Gases (CO2, CH4, NOx etc)
Combustion of Fossil Fuel (Industrial Activity)
5Descriptionof Climate Change
Since the industrial revolution, The Increase of
Concentration
Carbon dioxide Methane Nitrous oxide
30
more than 100
15
6Descriptionof Climate Change
The Increase of GHGs Concentration
Temperature Rise
Increase of ET
Variation in Precip.
Sea-Level Rise
7Descriptionof Climate Change
Scenario 1 (Watson et al.,1996)
Based on the current trend,
It would Rise up to 1ºC by 2100
8Descriptionof Climate Change
Scenario 2 (IPCC,1999)
Assuming 2 X CO2,
It would Rise by 2.5ºC (1.5-4.5 ºC )
9Descriptionof Climate Change
Sea-Level Rise
According to the estimate of IPCC,
The Total Average Sea- Level Rise
about 12cm by 2030 50cm by 2100
10Descriptionof Climate Change
- The Climate Changes affect
-Agricultural production -Water Supplies -Human
Health -Terrestrial Aquatic Ecosystem
11The Effects of Climate Change on Vegetation
Bertram Ostendorf et al. (2001)
Assumption 1ºC -10 of Precip.
Changes in forest type at 37 of total forest
area (15-19 º, 145-146 º)
12The Effects of Climate Change on Vegetation
- Lourdes Villers-RuÃz
- Irma Trejo Vánzquez (1998)
-
Assumption 2 X CO2
52-58 change in climate types of Mexicos forest
24 from 33 NPA (Natural Protected Areas) would be
affected!
13The Effects of Climate Change on Vegetation
The elevated global atmospheric CO2
concentrations will influence natural vegetation
directly, increasing photosynthesis and growth
(Jarvis, 1998).
14Report of Deforestation
- Terrestrial Ecosystem
- A Large Store of Carbon
- Containing
- 3 X C of the atmosphere
15Report of Deforestation
Forest Ecosystem
60 of the terrestrial carbon pool
Particularly, the Tropic Forest Holding 2/3
of the worlds diversity
16Report of Deforestation
- Deforestation at Amazon Frontier
gt2 million hectares (ha) each year (Steininger et
al., 2001, etc.,)
15000km2year-1 (1978-1988 ) (Skole and Tucker ,
1993)
21000 to 80000 km2year-1 (Skole and Tucker,
1993).
17Report of Deforestation
- Purposes of Deforestation
Pasture Logging Agricultural Cultivation
18Report of Deforestation
Agricultural Expansion
Associated with 96 of 152 deforestation cases
2 of global land area in 1700
13 1n 1990
19Impacts of Deforestationon the Global Warming
Production of GHGs (CO2, CH4, N2O )
20Impacts of Deforestationon the Global Warming
- Consequences of Land Clearing
Burning of Forest
GHGs Aerosol Emission
Cultivation
C Oxidation, N Mineralization Denitrification
21Impacts of Deforestationon the Global Warming
Carbon released to the air
1.6-2.4 Pg of C
25 of CO2 at present
22Impacts of Deforestationon the Global Warming
Methane released to the air
10Mt of CH4
According to IPCC, 204Mt C year -1
