2. Gran Chaco Americano Region
• It covers approximately 1 millon square kilometres
• It’s the largest Dry forest ecosystem in South America
• Encompasses central-north region of Argentina, west of Paraguay,
and the south east region of Bolivia.

3. The Project
• Sustainable Land and Forest Management in the transboundary
ecosystem of the Gran Chaco Americano
• Multi focal areas (Land Degradation, Biodiversity, Climate Change)
• Countries Involved: Argentina – Bolivia – Paraguay
• Funding Source: Global Environment Facility
• Participating Agencies: UNEP, UNDP, OAS

4. • to determine the carbon stocks through a methodology that can be
used in an initial situation (baseline) and subsequent monitoring
for which Permanent plots were selected by Land Use type and
SFM / SLM practices installed
• Institutions involved:
• Formosa National University – Argentina
• Forestry Investigation Institute of Bolivia
• Asuncion National University – Paraguay
• Period of measurements in the three countries(field/office):
May 2013 - March 2014
Objective

5. SELECTION OF PLOTS
Based on Land Use type:
(I) native forest; (II) Silvopastoral use; (III) agroforestry use; IV)
Agrosilvopastoral use; (V) Agricultural use (maize, soy, peanuts,
citrus); VI) Livestock use (grassland and forest with goats and
sheep).
- Methodology of measurement based on the IPCC and equivalent
between the countries
- All land uses evaluated are representative of the region

6. LOCATION OF PLOTS
A total of 42 plots in three countries that make up the Gran Chaco
Americano:
- 18 plots in the Chaco of Argentina
- 16 plots in the Chaco of Bolivia
- 8 plots in the Chaco of Paraguay

8. Measured Carbon Pools

RESULTS AND CONCLUSIONS

11. RESULTS AND CONCLUSIONS (cont.)
• The highest values of carbon content were found in Tall Forest
(200 - 220 ton / ha)
• The xerophytic forests corresponding to the Dry Chaco, with soils
of the order Alfisols, limited by drainage and soil sodicity, seem to
retain less carbon
• The lowest value (38.7 ton / ha) occurred in a forested plot with
carob trees (Restoration lot) in the absence of management of the
shrub stratum. In this sample 98% of carbon content was as soil
carbon
• Measurement of Soil Carbon content under different land uses.

12. RESULTS AND CONCLUSIONS (cont.)
• Spanish tutorial for filling Carbon Benefits Project platform
• Project Scenario developed through CBP platform
• Network of Carbon Experts in the Chaco Region
• Investigation lines to be encourage relative to Carbon Measuring and
Monitoring in the Gran Chaco region
• Institutional Strengthening for Universities
• Availability of the information through project website (in process)
• Access to Carbon measurements database supported by the National
Observatory of Land Degradation and Desertification of Argentina.
(www.desertificacion.gob.ar)
• Presentation of Carbon Content assessment in the Land Degradation
Neutrality workshop carried out in Buenos Aires, Argentina

13. Lessons learned
• There is a lack of information about alternative productions related to
its impacts over Carbon Content (handmade products, apiculture,
goma brea, etc)
• A second measuring of carbon content is needed in permanent plots
installed in the Chaco Region.
• We need to strength the Network of Carbon Experts in the Gran Chaco
region
