Forest Resources Assessment (FRA) : NGI (National Geographic

Inventory) coordinates the response of France.

Convention of Biological Diversity : NGI provides data.

Forest Europe : NGI involved in the creation of reports on sustainable management indicators of European forests.

OCS GE : Land cover classification – Large scale To better understand the consumption of natural, agricultural and

forestry territory and control the evolution of the land artificialisation.

National classification shared by all users and producers. Classification compatible with existing regional nomenclature or project (as

possible) - Compatible with Corine Land Cover (European classification). France and overseas department -> in French Guiana, it’s managed by

Environment Office and ONF provides data and participates in the reflexion.

This project has just started in French Guiana.

CORINE Land Cover (CLC) :

geographic database produced in the European Coordination of information on the environment program called CORINE.

This biophysical inventory of land cover provides a geographic reference information for 38 European countries.

Program continuity and diffusion of CORINE Land Cover data are controlled by the European Environment Agency.

The producer for France is the Service of the observation and statistics of the Ministry for the Environment.

Photo-interpretation of satellite images, with support additional data.

Production scale is 1/100 000. 3 data bases in Europe: 1990, 2000 and 2006 for land use and land

use changes. For French overseas department (part of Guyana - band of 20 km wide

along the coast) : 2 versions are available for the years 2000 and 2006 and changes.

It was not satisfactory for French Guiana -> Regional mapping developed by ONF -> Coastal expertise

National Protocol

Kyoto protocol :

International agreement aimed at reducing greenhouse gas emissions and which is in addition to the United Nations Framework Convention on Climate Change which participating countries meet once a year since 1995.

Signed on 11 December 1997 at the 3rd Conference of Parties to the Convention (COP 3) and entered into force on 16 February 2005.

This protocol was designed to reduce, between 2008 and 2012, at least 5% from the 1990 level emissions of six greenhouse gases: carbon dioxide, methane, nitrous oxide and three substitutes for chlorofluorocarbons.

In 2009, 184 countries have ratified this protocol. Inventory realized by CITEPA for Environment Ministry, conducted

from the surface states. Surface state are realized by a statistical survey on the ground, except in the

overseas departments. 3 dates of reporting : 1990-2008-2012.

For French Guiana : 1990 and 2008 was realized in France, with a

partnership with ONF Guyane / 2012 was realized in French Guiana by ONF Guyane, with a partnership with IGN.

Objectives of the project : In the Kyoto Protocol framework : reduction of GHG emissions To produce inventories for commitment periods : 1990, 2008 and 2012

Methods Based on the existing method (developed and approved by IPCC in

2006) Statistical inventory ≠ wall to wall mapping On the basis of stratified sample points By visual photo-interpretation of satellite imagery

Landsat Images for year 1990 SPOT images for years 2008 & 2012

To be combined with emission factors Dendrometric expertise carried out in 2005 by ONF, CNRS and CIRAD

(One global tree biomass per hectare for French Guiana forest 350 t/ha)

From existing inventory data and experimental protocols

COASTAL EXPERTISE

Coastal band = 8% of the territory 90% population Special ecological environments.

Conflict of Interest -> Need a reference study. Existing studies in 2001, 2005, 2008 and 2011.
