What is participatory three-dimensional
modelling (P3DM)?
P3DM consists of a community-based mapping method which
integrates local spatial knowledge with data on land elevations
and sea depth to produce stand-alone, scaled and geo-
referenced relief models.
Its core objective is to add value to traditional knowledge and
facilitate grassroots influence in policy-making.
Once the model is completed, a geo-referenced grid is
applied on the model to facilitate data extraction and/or
import, digitisation and plotting.
The possibility of exporting to and importing data from GIS
provides a bridge between technical and community-
generated knowledge
Brief review of its evolution in the Caribbean
region
Four models previous to 2012: Guyana and Haiti
2012 CTA intervention: The model of the entire island of
Tobago
8 other models built in the region since 2012 (5 direct
beneficiaries of the CTA 2012 intervention)
6 models were built to advise on action for climate change
The island of Tobago
To make local and traditional knowledge and values more
recognized and more authoritative in decision making about
climate change adaptation in the Caribbean region
Union Island, SVGTo document, share, and combine traditional and other forms of
knowledge to identify the risks from climate change and extreme
climate events and to recommend the adaptation policies and
actions required.

The Building of the model
Partners:
The Grenada Fund for Conservation Inc. (GFC)
The Nature Conservancy (TNC)
The Technical Centre for Agricultural and Rural
Cooperation ACP-EU (CTA)
approximately 400 persons from the communities and
key decision makers.
The model was used to identify risk from climate change
and extreme climate events and to make
recommendations to deal with the risk
The model’s construction built on the efforts of TNC’s At
the Water’s Edge (AWE) climate change resilience
initiative
Executive Director of GFC, Tyrone Buckmire, said that the
model “helped crystallize what needed to be done”
Results
GFC, with the assistance of TNC, have sourced nearly
USD 200,000 to fund restoration of the entire coastline in
the Grenville area but USD 300,000,000 is still needed

Contributions to improving regional capacity in the
practice of P3DM
Benefits of P3DM to action on climate change
in the region
Allows local communities to participate in decision-making
Helps to identify on-the-ground action as well and priority
policies
Brings relevant knowledge – both traditional and indigenous –
into consideration when decisions are being made on climate
change
Increases the capacity of community groups (e.g. increased
knowledge about climate change impacts and adaptation,
event management, access to financial resources and
training with external entities)
Builds buy-in for plans for action on climate change
Facilitates coordination and collaboration among sectors
Keys points to consider
The practice should be facilitated by an entity with ia strong
capacity for event management, member of a network of
partners that are able to contribute to effective analysis and
planning on climate change
The practice to be most effective must build on a process of
participatory needs analysis.
The practice needs more effort exerted:
in communication (so more can know about the benefits of its
use);
in documentation ( so lessons learned and experiences are
recorded); and
in data extraction ( so the data is portable and available to
stakeholders external to the site).
