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.
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
• 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
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
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
Measured Carbon Pools

RESULTS AND CONCLUSIONS
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.
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
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
