Introduction and studies regarding agroforestry to climate change

1. Agroforestry
& Climate
Change

2. The double potential of agroforestry to
address climate change issues
2
⊷ Greenhouse gas–mitigation strategy through
carbon sequestration
⊷ Sustainable adjustment to changing conditions
because agroforestry systems can be called
perennial

3. Agroforestry
is a
landscape-
scale
approach,
thus favours
synergy
between
adaptation
and
mitigation

⊷ agriculture to agroforestry significantly
increased soil organic carbon an
average of 34 percent
⊷ pasture/grassland to agroforestry
produced soil organic carbon increases
of about 10 percent, on average
⊷ forest to agroforestry led to losses in
soil organic carbon stocks in the top
layers, while no significant differences
were detected when deeper layers
were included

Conservation in the AF Systems in Benguet

⊷The Chayote-based AF
- Based on the survey conducted 52% of the AF farms
surveyed had chayote as its major or one of its major component
- Alnus had been proven by farmers to enhance fruiting
of Chayote since it fix N and it’s’ litter is a good compost material
- Chayote have the ability to eliminate understory
vegetation and grasses with continued planting (due to shading
/absence of fallowing), the soil becomes more prone to erosion
through time
⊷ The coffee-based Agroforestry
- The coffee based AF had the highest C pool for
understory because of this woody component

10. 10
⊷The Anthurium based AF
- Multi-layering allows more C storage in AF farms per
unit area.
- In the evaluation of C stock in this area, trees in the AF
farms are mostly small diameter trees but more trees (21
trees/200sqm) and crops had been incorporated in the system.
⊷ Low Elevation AF Systems
- Benguet mostly used crops that are sun-loving such
as tiger grass, rice and pineapple
- Only trees that are of broken-type crown such as
Gmelina, Kakawate (Glericidia sepium), Ipil-ipil (Leucaena
leucocephala), breadfruit, guava, Akleng parang (Albizia procera)
and the like can be effectively incorporated in this AF system.
- Shade tolerant crops such as root crops, cassava,
palms, bamboo can also be integrated

In comparison to other land-use type:
- Benguet AF – 208.2 t ha-1 of C
1. Natural forest – 254 t ha-1 (Batanicla, et. al. 2003)
2. Young pine forest – 90.1 t ha-1 (Lasco, 2000)
3. Rubber agroforest 104-116 t ha-1 (Lasco, 2000)
4. 8-year old alnus 123.76 (Paran, 2013)
5. Burnham park mix stand dominated by pine tree 73.2
(Lumbres, 2009)
6. Narra-Cacao 191.6 and Gmelina-Cacao (Banaticla, et. al,
2003)

Three agroforestry systems in Bukidnon
1. Mixed Multistorey system
2. Taungya agroforestry system
3. Falcata-coffee multistorey system
……..Carbon stock assessment of three
selected agroforestry systems in
Bukidnon, Philippines.pdf

14. 14
⊷Mixed multistorey system
- Tree biomass density with (67-89 Mg ha-1)
- Aboveground biomass amounted 83 Mg ha-1
- Carbon content of herbaceous vegetation with 37%
- Total carbon stock was 162 MgC ha-1
⊷Taungya agroforestry system
with 3-5 year-old G. arborea as the dominant tree component
- Tree biomass density with 21-36 Mg ha-1
- Aboveground biomass amounted 31 Mg ha-1
- Carbon content of herbaceous vegetation with 40.5%
- Total carbon stock was 174 MgC ha-1

15. 15
⊷Falcata-coffee multistorey system
- Tree biomass density with 14-17 Mg ha-1 for a 5-
year old P. falcataria trees
- Aboveground biomass amounted 18 Mg ha-1
- Carbon content of herbaceous vegetation with 27%
- Total carbon stock was 92 MgC ha-1
Total storage of the 3 agroforestry system is
92 MgC ha-1 to 174 MgC ha-1
