Boundary of the Project Areas
The project boundary should geographically delineate allsequestrations and emissions that are significant, can be
attributed to the project and are under the control of the
project participants.

Designated National Authorities, have the role of decidingfor their country where to lay the thresholds from a rangedetermined at COP9, namely:
Minimum tree crown cover value between 10 and 30 %Minimum land area value between 0.05 and 1 hectare;
Minimum tree height value between 2 and 5 metres.
The definition of forest accepted by India is
Forest is a minimum area of land of 0.05 ha with treecrown cover (or equivalent stocking level) of more than30% with trees with the potential to reach a minimum
height of 5 meters at maturity in-situ.

Eligibility of Lands
31st December 1989 Rule
no forest to be present within the project boundaries between
31 December 1989 and the start of the project activity
(The tool requires proof that the area is not currently forest, that it wasnot forest on 31 December 1989, and that at no intermediate time wasit forested and subsequently deforested)
Satellite data set of the start, current and intervening periods
status of forest as per the definition

Analysis of Eligibility of Land Parcels by FSI in the HPMid-Himalayan Region Afforestation Bio-Carbon Project
The interventions proposed under the BC project makes the
villagers a strategic seller of carbon credits under the CDM
Afforestation on 12000 Ha involving 600 Gram Panchayats
Parcel of lands are spread over the nine districts of the state more
than 1200 polygons
Focus is only on afforestation for which the farmers will receive cashincentive (by being a potential seller of carbon credit) on three types
of lands;(i) non-arable agriculture waste land,
(ii) degraded forest land,
(iii) degraded common property land

Methodology
GPS survey of all the land parcels was done to generateboundaries and measure area
Boundaries of the patches from GPS provided vectorcoverage in GIS
Satellite images of the two dates were co-registered using
image-to-image rectification approach (Autosync software) Satellite images of the two dates i.e prior to December 1989
and the current one were classified using hybrid
classification approach to give forest cover in three canopydensity classes; < 10%, 10-30% and >30%
Vector coverage of the patches of lands was overlaid on theclassification to analyze each patch for canopy densitybefore 31st December 1989 and currently

In the first phase of the project, eligibility of 97 parcels oflands has been examined
the area of parcels of land range between 1.8 ha to 52 ha
93 parcels of lands were found to confirm to the eligibility
criteria
documentary evidence (maps) showing eligibility of eachparcel of land was generated

Problems Faced in this Approach
Shift in the GPS (generated) boundaries and the
Satellite Image The shift is more pronounced in hilly terrain (if ortho-
rectified image is not being used)
Traversing boundaries of the larger land parcels (>5ha) with GPS in hilly terrain is difficult and timeconsuming exercise
At places in the shadows, GPS signal is weak orabsent
-
8/8/2019 TS3-2-SubhashAshutosh
24/67
Modified Approach
instead of traversing the boundaries of the identified parcels oflands, only GPS observation of the co-ordinates of a central point ofthe parcel is taken
details of land cover and features around the identified parcel of landis recorded on a form
point locations of the land parcels are downloaded to give a point
vector coverage
point coverage showing central points of the parcels are thenoverlaid on the remote sensing data
details recorded on the field forms are then also used to delineate
the identified parcels of the lands on the remote sensing data by on-screen digitization of the polygons
multi spectral images (FCCs) would be more helpful in accuratelydelineating the identified polygons because of enhanced
interpretability of the features seen in tonal variations
-
8/8/2019 TS3-2-SubhashAshutosh
25/67
an alternative to the multi spectral image could be fused image of
panchromatic image (high resolution) with the multi spectral image(somewhat coarser resolution)
this method saves cost and time significantly
it is also more objective in approach because, before delineating the
polygons of the land parcels, the applicability for eligibility of lands
under the 31st December 1989 Rule is also examined
once the land parcels have been delineated on the satellite image,suitable maps of the same on large scale say 1: 10,000 or larger
showing high resolution satellite image in the background can begenerated to facilitate demarcation of the lands on the ground

Stratify the Project Area
The stratification should be carried out using criteriathat are directly related to the variables to be
measured and monitored for example, the carbon pools in trees
there is a trade-off between the number of strata andsampling intensity.
the purpose of stratification is to partition natural
variation in the system and so reduce monitoringcosts.

Potential stratification options
Land use (for example, forest, plantation, agroforestry,grassland, cropland, irrigated cropland);
Vegetation species (Forest type); Slope (for example, steep, flat); Drainage (for example, flooded, dry); Age of vegetation;
Proximity to settlement. Typically, a project might have between one and six
strata.

application of Geomatics in preparation of PDD is anecessity, rather than an option
Geomatics based methodologies in survey, mappingand natural resource assessment are well established
specific methodologies with respect to PDD forLULUCF projects under CDM need to be standardised
