Participatory 3D Modelling or P3DM in short, is a community-based mapping method which is spreading in the Caribbean Region. It facilitates planning and action-taking on climate change related issues. Considering the potentials of the process, efforts are needed to promote the success stories of its use to date. This presentation at the Caribbean Pacific Agri-Food Forum in Barbados (206 November 2015) is an important step in promoting the practice in the region. Neila Bobb-Prescott's participation in the Agri-Food Forum has been supported by the Technical Centre for Agricultural and Rural Cooperation ACP-EU (CTA)

3. 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.

4.  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

5. 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

6. 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

7. Union Island, SVG
To 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.

8. Telescope, Grenada
To 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.

9. Roxborough, Tobago
Using P3DM, to support the development of climate change
strategies and policies

10. St. Vincent and the Grenadines
Using P3DM to facilitate discussion on planning for storm surges
using 25, 50 and 100 yr projections

11. Soufriere-Scott’s Head, Gallion area,
Dominica
Spatial planning to improve resilience to climate change and extreme
events in the Soufriere-Scott’s Head, Gallion area in Dominica

12. Case study: P3DM supports the implementation of
Ecosystem-based Adaptation in Telescope, Grenada

13. Impact of hurricane Ivan

14. 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

15. Executive Director of GFC, Tyrone Buckmire, said that the model
“helped crystallize what needed to be done”

16. 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
Reef and mangrove restoration
 Contributions to improving regional capacity in the practice of
P3DM

17. 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

18.  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

19. 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.

20.  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).
