What do we know about Peruvian peatlands? : Ecosystem services, threats and Regulatory framework
¿What do we know about
Peruvian peatlands?

Symposium: Tropical South American Peatlands:
distribution, impacts of disturbanceand knowledge gaps.

Ecosystem services, threats and Regulatory framework
Peatlands
• Oxygen deficient wetlands. Saturated
condition allow peat formation.
• 2,8 % of the Earth´sSurface(Xu et al. 2018)
→ 815 Gtof C in the soil (Yu et al, 2012).
Perú: One of the richest countries in
tropical peatlands (Gumbricht et al.2017).

III. Importance- Ecosystemservices
❑ Important carbon reservoir
→Pastaza Marañón (3% forest area)=3,1
Gt C (Draper et al.2014)(50% of C stored
in aerial biomass of Perú)
→Average C accumulation rates: up to
66 g C m-2 year-1 (Lähteenoja et al. 2009)
→Peat dephts: ~7.5 m (Amazon) and up
to 10.5 m (Andes).
❑ Regulation of the hydrological
cycle
III. Importance
❑ Home to unique biodiversity
❑ Livelihoods of local communities
✓ Amazon: > 50 species form part of local
community
✓ Andes: Animal husbandry is the main source of
income
❑ Important part of the cultural roots of many
indigenous communitites
Macaws (Ara ararauna)
Tapir (Tapirus terrestris)
Agouti(Dasyproctaspp.)
Mauritiaflexuosa
fruit Cinclodes palliatus
IV. Threats
• Amazon
✓ Explotation of oil and mining Resources
(24% of peatlands in Pastaza are located in
oil concessions,Roucoux et al.2017).
✓ Selectively felling female palms.
✓ Land-use change (plantations and rice
fields expanded in Madre de Dios, Ucayali
y San Martin).
✓ Overhunting
- Anthropogenic
IV. Threats
• The Andes
✓ Mining activities
✓ Road construction
✓ Overgrazing
✓ Peat extraction
• Coast
✓ Population expansion
✓ Fires
V. Regulatory Framework
• Commitment to conservation within the
framework of the Ramsar Conventionon
Wetlands.
• Some peatlands areas are in protected
zones.
• Important regulations on mechanisms for
the compensation of ecosystemservices
• DS N° 006-2021 MINAM
• There is no explicit inclusión in policies
related to climate change: REDD + and NDC
Conclusions
Peruvian peatlands…
They play an importantrole in the fixationand storageof C, their conservation,
sustainablemanagement and restorationare consideredkey among naturalclimate
solutions.
They are essential for adaptationto climate changethroughtheir provision of water-
related ecosystemservices, such as water storageand regulation,buffering against
floods, and waterpurificationat local and regional scales.
They are fragile ecosystemsthatare being damaged by anthropogenicactivitiesthat
include infrastructuredevelopmentand resourceextraction,and unsustainableuses or
practicesof varying intensity thatthreatenthem and increase their vulnerability.
Therefore,it is essential that Peruvian policies ensure the conservationand sustainable
use of peatlandsand prioritize them within the national climate and environment
agenda.
