Powerful maps: how building 3D models is helping rural communities to make their voices heard

A process of building three-dimensional physical models in a village setting is helping to bring together traditional and modern scientific knowledge to tackle challenges ranging from soil degradation to land use planning, and from forest management to climate change. The technique, known as Participatory 3-dimensional modelling (P3DM) enables marginalised communities to present their territory – together with their own valuable knowledge – in a visual form, offering them the opportunity to protect precious natural resources from outside threats and preserve them for future generations. Some of the field experiences have been published in a new report. The Power of Maps: Bringing the third dimension to the negotiation table is published by the Technical Centre for Agricultural and Rural Cooperation (CTA), which has been in the forefront of promoting the practice across African, Caribbean and Pacific (ACP) countries.

Developed in the early 1990s in Southeast Asia, P3DM is rapidly gaining ground in other parts of the developing world. Participatory 3D models, made out of cardboard and illustrated with coloured paints, pushpins and yarn, portray land cover, such as farmland, rivers and forests, as well as other features, including coastal resources and sea depth. Uniquely, they also depict traditional knowledge, such as ancestral land rights and sacred places. These features are generally supplied by elders in the community, while younger members build the map itself. The result is a free standing relief model which provides tangible evidence of local knowledge, serving as an effective tool for analysis, decision-making, advocacy, action and monitoring.

“Knowledge built up over time and passed from generation to generation represents a unique asset for rural communities when it comes to their land, forest and aquatic resources,” said CTA Director Michael Hailu. “The ability to collate and geo-reference local knowledge and represent it in the form of 3-dimensional maps offers a unique opportunity for local communities to have a voice in decisions on how to sustainably manage their resources.”

Often, the process of participatory 3-dimensional modelling is in itself empowering, bringing communities and generations together and helping them to visualise the extent of their resources, and how climate change and other threats, such as mining and deforestation, may be affecting them. Once completed, the physical model remains with the community.

Case studies presented from Ethiopia, Fiji and Madagascar show how P3DM has led to the development of community-driven natural resource management plans. Other examples of P3DM initiatives described in the book demonstrate how the technique can give marginalised rural people a voice to make their case heard. In the Democratic Republic of Congo, the Bambuti-Batwa pygmy community used a P3DM exercise to drive talks on what they claim is the injustice of being evicted from the territory they had inhabited for generations.

Three-dimensional mapping has helped the Kenyan hunter-gatherer Ogiek tribe to document its ancestral land rights and knowledge systems. Meanwhile, In Tobago, a Caribbean island that has suffered a series of extreme climate events in recent years, P3DM has been used to guide community-driven disaster risk reduction strategies.

South-South cooperation is helping to make the practice of participatory 3-dimensional modelling become better known and CTA has been closely involved in efforts to share training and facilitation between Caribbean and Pacific Islands and a range of African countries.

Experiences of P3DM can generate other benefits, such as offering new skills and self-confidence to individuals engaged in the process and funding for communities to implement activities. A case in point is Grenada, where a participatory 3D model had a direct impact on the community that created it, by mobilising donor funding for climate change adaptation on a stretch of the coastline badly affected by hurricane damage.

“Participatory 3D modelling, the process documented in this book, has proved to be successful in eliciting substantial amounts of what is termed as tacit knowledge from individuals, to collate individual world views into a shared, visible and tangible representation of collegial knowledge,” said Senior Programme Coordinator Giacomo Rambaldi, who has led CTA’s involvement in P3DM. Adding ‘location’ to any piece of information or datum makes it even more relevant. Hence P3DM enables knowledge holders to visualise and geo-reference their traditional knowledge and to engage outsiders in a peer-to-peer dialogue.”

Participatory mapping processes for data generation and exchange in SIDS by Aly DeGraff at the Caribbean-Pacific Agri-Food Forum in Barbados

Participatory mapping processes for data generation and exchange in SIDS from CTA

Participatory mapping is the solicitation and incorporation of geospatially focused local knowledge in bottom-up decision-making processes. It provides a wide decision-making base, taking into consideration the collaborative collection and validation of data while building ownership in the generated data. Participatory mapping can be used as a powerful tool to strengthen public participation in governance and social change in agribusiness communities.

Aly DeGraff delivered her talk at the Caribbean-Pacific Agri-Food Forum in Barbados organised by CTA and partners.

Participatory 3-Dimensional Mapping (P3DM) for Disaster Risk Reduction (DRR): A Field Manual for Practitioners - New manual released

There has been a recent impetus towards the use of Participatory 3-Dimensional Mapping (P3DM) for Disaster Risk Reduction (DRR).

This has created a demand for appropriate skills to conduct P3DM for DRR among practitioners, including staffs from community-based organizations, NGOs, local government offices and scientific organizations.

This manual aims, in response to such a need, to assist those practitioners in facilitating disaster risk assessment and in planning activities geared towards reducing that risk. It provides a comprehensive but flexible framework which includes 16 methodological steps and associated activities, suggested materials and potential outcomes and applications.

This is a publication of CAFOD, a member of CARITAS international. CAFOD is the official overseas development and relief agency of the Catholic Church in England and Wales.

Who Counts? The Power of Participatory Statistics

Local people can generate their own numbers – and the statistics that result are powerful for themselves and can influence policy. Since the early 1990s there has been a quiet tide of innovation in generating statistics using participatory methods. Development practitioners are supporting and facilitating participatory statistics from community-level planning right up to sector and national-level policy processes. Statistics are being generated in the design, monitoring and evaluation, and impact assessment of development interventions. Through chapters describing policy, programme and project research, Who Counts? provides impetus for a step change in the adoption and main-streaming of participatory statistics within international development practice.

The challenge laid down is to foster institutional change on the back of the methodological breakthroughs and philosophical commitment described in this book. The prize is a win–win outcome in which statistics are a part of an empowering process for local people and part of a real-time information flow for those aid agencies and government departments willing to generate statistics in new ways. Essential reading for researchers and students of international development as well as policy-makers, managers and practitioners in development agencies.

'This is a timely compilation of ground-breaking work which adds up to a powerful agenda for transformation. This book shows how we can quantify the qualitative, build the active agency of excluded groups and generate participatory statistics that have greater rigour and legitimacy than most conventional statistics.’ David Archer, Head of Programmes, ActionAid

Knowledge holders add value to the 3D model of Tobago

Historical and cultural knowledge emerges along with awareness on environmental change

SCARBOROUGH, 06 October, 2012.  Excitement is growing as the blank 3D model is populated with data.  What is astonishing is that nobody uses satellite images or existing maps where to source information.  All data comes from memory, and one added piece of information offers new cues to memory, hence everybody is discovering and learning by doing.

A team from Golden Lane add their data to the model

Day by day, more information is added to the once blank model.  The second group of informants arrives to transpose their information.  And still, members from the first group of informants are returning to the workshop because, according to them, they went off, did some research and have returned to “add more value to the model”.

The residents of Tobago, the actual custodians of local and traditional knowledge are eager to put their stamp on the model.  As the updating of the map legend continues, some of them are resolute in their view that present as well as past names of map features, like points, areas and lines must be included.

The participatory 3D model exercise is being facilitated by the Caribbean Natural Resources Institute (CANARI) and the University of the West Indies (UWI) with financial and technical assistance from The Technical Centre for Agricultural and Rural Cooperation ACP-EU (CTA) and the United Nations Development Programme, Global Environment Facility - Small Grants Programme (UNDP GEF-SGP).

Historical perspective

The excitement of the participants echoes around the Island and the P3DM initiative  is attracting keen interest from Tobagonians from all walks of life.  Laura Williams of Golden Lane returns to the workshop with Lyris Walker and Veslin Alleyne in tow; they have information for the model.

Gang Gang immortalised on the model!

Lyris says she is glad to be a part of the project because it is “for the people by the people”.  Pointing to places she had forgotten about, she says the project is successful because it is “very educational”.  She jogs her memory for details while consulting The changing society of Tobago, 1838-1900: Vol I and II a historical publication written by Susan E. Craig-James.  This historical publication should inform the P3DM, says Lyris.

Lyris, Laura and Veslin are excited to see the point on the model which identifies Gang Gang Hill in Golden Lane.  They tell of the legend that gave the hill its name: Gang Gang Sarah was a witch who flew from Africa to meet members of her family who were captured and brought to Tobago after being sold into slavery.  In Tobago, Gang Gang Sarah met and married Long Tom.  After her husband died, she attempted to fly back to Africa, but fell to her death from the top of the silk cotton tree which she had climbed to begin her journey.  She could no longer take off because she had eaten salt and salt makes it impossible for witches to fly!

Tobago has a rich cultural history, but the legends are heard less frequently as the years go by.  To preserve the island’s past, a Heritage festival is held annually to celebrate all aspects of the island’s history.

Climate change adaptation

Contributing to the participatory 3D model overwhelms Bryan Bain of Belle Garden.  He understands the importance of the exercise because he has seen the effects of unsustainable harvesting practices and climate change in his community.  He talks of crab catchers harvesting thousands of crabs weekly.

A fisherman from Castara is oriented to
the model by one of the trainees

He admits that he also harvested over two hundred crabs per week, in 2005.  Back then, he says, crabs walked “by the hundreds in the wetlands”, while at present only four or five perch above their holes.  As a result of the dwindling crab population, Bryan says he has stopped catching crabs and is now assisting in encouraging hunters to leave the young crabs to thrive.  He adds that he joined the Belle Garden Wetlands Association and Environment Tobago to meet like-minded people to preserve the environment.

Bryan also points to deforestation as a major problem in his area.  This, he observes, has lead to the shortage of wildlife in the forest, among other things.  He feels that the P3D model will make members of the community more aware of the damage they are causing.  Increased awareness, he notes, should bring about enough change in people's attitudes and trigger changes in the way they act.  He plans to build a P3D model of his village to enhance tourism.

Similarly, Goldberg Job, informant from Belle Garden, says people have to be encouraged to adapt to climate change by changing their lifestyles.  He says people must be told to tie the roofs to their houses to prevent these from being blown away during adverse weather conditions.  Additionally, he notes that fishermen should build bigger boats and invest in technology in order to continue fishing further afar from the coastline.  He wonders whether architects are part of the P3D model-making.  He is told that he is the architect, as well as the other informants.

The work on the participatory 3D model of Tobago continues apace.  Another group of informants is expected on Sunday.  If the trend continues, the same group of informants that came on Saturday and Friday will return to further contribute data on the model.

Participatory 3D model of Tobago seen as time capsule

SCARBOROUGH, 07 October 2012.  On the morning of Sunday 7 October, the air in the room where the participatory 3D model is being built, is tense but hopeful.  Trainees, facilitators and informants work at a steady pace, but there is animated discussion on the ICC Twenty 20 Cricket World Cup game between the West Indies and Sri Lanka, being played halfway across the world.  Later in the day, after much anxiety, the West Indies is declared the winner of the cricket match and there is a brief pause to celebrate!

putting detail onto the model

More than anything else, the screams of joy reverberating around the room remind the trainee-facilitators, facilitators and informants of their common heritage and shared geographical space.  The reflection on the impacts climate change is having on natural resources and on the actions being taken to deal with these changes takes on a new dimension.

Jacinthe Amyot of IOC-UNESCO/Marine Affairs Program, Dalhousie University/Canadian International Development Agency IYIP says that after hearing fishermen talk about the effects of the Orinoco river on the Tobago shrimp fishing industry, she has developed a keen appreciation for its effects.  She says this information will inform her actions in the future.

Cocoa farmers discuss their
contributions to the model

Jacinthe is one of a number of persons participating in this capacity building event, representing different government, inter-governmental, civil society and academia from across the Greater Caribbean.  These persons have been in Tobago since September 29th to participate in this training which is meant to introduce a participatory mapping method which could be adopted across the Caribbean region as it previously happened in Africa and the Pacific.

Meantime, a steady stream of informants continues to trickle in.  They had stayed at home in the earlier part of the day to watch the World Cup cricket match while others had gone to church, as is the local tradition.  Members of the Cocoa Farmers Association of Tobago (TCFA) and various fisherfolk associations throughout the island transpose their spatial knowledge on the model with the guidance of the facilitators.  The farmers talk about the climatic changes they have observed and they also identify areas where cocoa farms exist and verify other bits of information on the model.  The farmers share how changes in climate have affected the cocoa crop cycles and caused a high level of unpredictability over the years.

Clement Bobb, President of the Cocoa Farmers Association, says the “sporadic rainfall - short burst of intense rain followed by hot sun – means that there is a longer bearing season”.  This kind of weather is causing the trees to flower all year round, he says.  Mr. Bobb adds, “we do not know when to plant”.

A fisherman adds information to the model

Mr. Bobb does not own a cocoa farm but manufactures dark chocolates under the ‘House of Orlando’ brand.  Talking about the value of the P3DM workshop, the chocolate entrepreneur says its value will last for generations as it is a time capsule documenting the status quo of the island.

Similarly, informant Andre Greene, a fisherman from Parlatuvier, says the P3DM exercise is generating “vibrant information for the coming generations”.  He thinks that segments of the model would have to be updated as changes occur due to the impact of climate change.  On the issue of fish stock, Andre says it is “getting harder to find fishes in the sea, all year long”.  He has to go further out to the sea and stay further away from other fishing vessels.  He mentions that while he appreciates the value to the country of natural gas exploration taking place at Block 22 just off the north coast of Tobago, he has concerns that this activity may be a contributory factor to the low level of fish stock.

Continuous Evaluation

The first act of the day, as trainees and facilitators gather, is the assessment of the previous day’s activities and agreement on the agenda for the day.  Today, Nicole Leotaud, CANARI’s Executive Director and conservation biologist, takes the debriefing session a little further and does an assessment of the entire workshop.  She looks at the areas on the model that have been mapped and examines the information added about Tobago’s resources and the effects of climate change.  How locals adapt to the changes is also a part of the assessment, to the extent to which the information is being captured on the model.

In the meantime, as informants come and go, they transpose their mental maps on the model and check existing ones.  It is a process of constant cross-checking and verification marked by recurrent negotiations.

There is discussion, sometimes heated, on where lines, areas and points should be located.  When there is no consensus, CANARI facilitators and Participatory GIS experts Kenn Mondiai from Papua New Guinea and Kail Zingapan from the Philippines come in to assist.

The workshop is soon drawing to a close, with only four more days to go.  In that time, the facilitators look forward to welcome new teams of informants coming from the south western end of the island.

Blank 3D model of Tobago accommodates first set of community inputs

Informants express pleasure at being part of exercise

SCARBOROUGH, 04 October 2012.  Bubbling with excitement, informants who came from far and wide to help fill in the blank model of the P3DM of Tobago could barely contain themselves as they realize the importance of their knowledge.

Kail Zingapan, GIS expert being interviewed
by Clyde McNeil of Tobago Channel 5 

The room is buzzing with activity as the informants locate features on the map.  Four groups of trainee facilitators accompany Tobago residents in transferring their mental maps on the 3D model under the watchful eye of facilitators from the Caribbean Natural Resources Institute (CANARI), GIS expert Kail Zingapan from the Philippines and Kenn Mondiai of Partners with Melanesians (PwM). .

The island of Tobago, for which the participatory 3D model is being developed, is an island nation and part of the Republic of Trinidad and Tobago.  Tobago is the smaller of the two islands and has a land mass of approximately 300 km².  The P3D model represent the island at a 1:10,000 scale hence one centimetre on the model corresponds to 100 meters on the ground.  The island is home to the largest brain coral in the world and the oldest Forest Reserve in the Western Hemisphere - the Main Ridge Forest Reserve.

Democracy Walls

on the model based on her recollection from memory

Not only are informants transferring their personal knowledge of Tobago, and its surrounding waters up to a depth of -100 meters to the model, but they are also sharing their feelings about the activity on a "Democracy Wall" in a specially marked off area on the wall of the workshop area.

The "Democracy Wall" provides one additional channel for participants to express themselves.  To contribute to the Wall, the informants write their notes on small pieces of paper which they then post onto the Wall with tape.  Open ended headings such as ‘I believe …’ and ‘I feel …’ stimulate contribution.

Teenager Zenniethe Balfour of the Anse Fromage Ecological Environmental Protection Organisation - Golden Lane sticks her contribution to the Wall:  “I did not know Tobago is shaped like a snake”.  She says that listening to the contributions of others as they transfer images from their mental maps is a learning experience.  In fact, she says she is learning many new things about her community although she has been living there for the past eighteen years.

Asked to convey her feelings about contributing to the blank model, Zenniethe smiles broadly and says she feels “important”.  In terms of the value of the entire exercise, she says there is value in knowing the natural resources in one’s community.  “As you become aware you will instinctively protect”, she says.

Selecting data for the model

Goldberg Job of Belle Garden shares his views during the
orientation  session prior to engaging with the 3D model

Prior to inserting pins and outlining yarn on the model, informants had to agree on colour codes and symbols for particular features such as different types of forests, reefs and other features of importance to them that would be located onto the model.  Symbols and colours were associated with legend items to compose the map interpretation key.  Throughout the session, informants sought clarification on what types of information could be placed on the model and how they could symbolise it in line with the existing legend.

A fisherman asks why he is seeing government offices, seaports and airports but no banks on the chart.  CANARI’s facilitator Neila Bobb-Prescott responds by asking him to what extent the position of a bank is impacted by climate change.  He scratches his head, pinches his chin, nods and moves on to another question.

Laura Williams from Anse Fromage adds detail to the model

Before engaging with the model, informants take part in short orientation sessions with facilitators.  These sessions include mutual introductions, sharing information on the 3D modelling process, climate change and what the concept of “participatory” means.  The orientation sessions also sought to learn about the informants understanding of these concepts and their views on what value they felt the development of this model has for them and would have for Tobagonians.

Laura Williams from the Anse Fromage Ecological Environmental Protection Organisation is busy working on the model, identifying areas in her village, Golden Lane.  Golden Lane is a rural village on the north eastern end of Tobago.  The Great Courland is one of a few beaches in the world where the endangered leatherback turtles gather every year to lay their eggs.  She says she is devoted to ensuring that Golden Lane is well represented; she wants it to be known that the Courland Watershed, the Great Courland, is not so great anymore as it is being heavily impacted by climate change.  Noting that deforestation is a big problem in the area, she says man is contributing to  this destruction.

Laura says the P3D model will make people of the community more aware of the impact their actions are having on the environment.  People outside of the area will also be aware of the problems, she says.

With a wealth of information being shared and mapped by the knowledge holders, the workshop facilitators are looking forward to welcoming more and more members of the communities across Tobago who are expected to arrive over the coming week.

P3DM blank model of Tobago ready for accommodating community’s knowledge

SCARBOROUGH, 3 October, 2012. Facilitators working on the blank model for the P3DM of Tobago all agreed that... “it has been challenging!”

Looking at an example of a model during the orientation, they thought that building a model would have been an easy task, but reality turned out to be quite different.  Expressions of relief echo around the workshop area as the blank model is finally complete on day three of the project.  Yet, in the same breath, they also give heartfelt thanks for being among the 'chosen few' selected to be part of the workshop.  Facilitators are from regional and national non-governmental organizations, government agencies, inter-governmental technical agencies and members of academia.

Held in Tobago at the Mt. St George Blenheim Sheep Multiplication and Research Project, the workshop is being conducted by experts from the Caribbean Natural Resources Institute (CANARI) and the University of the West Indies (UWI) with financial and technical assistance from the Technical Centre for Agricultural and Rural Cooperation ACP-EU (CTA) and the UNDP Small Grants Programme of the Global Environmental Facility (GEF-SGP).

CANARI's project concept note of July 2012 states that the workshop’s aim is to get members of the community involved in "climate -related decision making" through a process involving the manufacture and use of Participatory 3D Models.

Confidence soars as the hands-on experience continues

Addana Pigott-Henry, an agricultural scientist working at CARDI, Tobago, says the experience for her was different from expectations, since she had envisaged a more formal lecture-style approach to the workshop.  After the hands-on experiences of the last couple of days though, she says she now feels empowered to assist in conducting a P3DM exercise with the help of experts.  She has learnt a lot from the interactive method and the lessons are invaluable, she says.  Addana, is of course happy that the workshop is being held in Tobago so that the regional and international participants can get a chance to experience the hospitality of Tobagonians and its rich and varied cuisine.

Meteorologist Anthony Moore of Barbados says that he is also fairly confident that if he was to build a P3DM, he would be able to do so as he is now equipped with adequate knowledge and experience.  Representing the Caribbean Institute for Meteorology and Hydrology (CIMH), Anthony says that at the beginning of the workshop he was lost and thought that building the model was a 'huge undertaking'.  His experience with maps and drawing, cutting and layering contours on a daily basis did little to allay his fears.  "A lot has been cleared up because of the hands-on experience," he admits.

Anthony acknowledges the value of a facilitation lesson shared by CANARI's Neila Bobb-Prescott and lists it as a highpoint of the workshop.  As a stakeholder in water resource management, he says the lesson is valuable and will help him to get information from farmers for an impact assessment study.  "Interaction with them would be easier,” he says.

Not unlike Adanna and Anthony, Adam Jehu of the Institute of Marine Affairs in Trinidad (IMA), also feels he now has the ability to construct a P3DM of an area and acknowledges that this approach to mapping is a "very novel way of capturing spatial data from the members of the community, the people who have the knowledge."  Adam is also grateful for the lesson on how to facilitate a P3DM exercise, since although he did know how to use GIS technology, he did not know how to build on community’s knowledge of the landscape.

Community insights

In the middle of one group orientation, a few residents popped in.  They stood around the model, and immediately without prompting, they started pointing out places in the island, the river, the forest and many other things, and recognized features on the blank model.  And almost as quickly, they pointed out features that were lacking on the model: Little Tobago, the reefs, the rocks, the islets.  They began to improve on this omission by contributing the names of the rocks and the islets that lie successively along a chain around the north-eastern tip of Tobago.

“This doesn't cease to amaze me when I see it happen.  Local people can immediately spot errors or omissions on GIS maps and correct them” noted Kail Zingapan.

Crucial lessons 

Participants create the storyboard using yarn, Playdoh
and other materials

Facilitators learned the components of two more aspects of the P3DM exercise on Wednesday.  The first was about monitoring and evaluation of the process.  CANARI’s Executive Director, Nicole Leotaud brought some clarity to the concepts and introduced the tool of participatory video (PV) which will be used in the evaluation process.  Desiree Sampson, videographer, gave tips on the shooting of videos.  This session featured a mix of hands-on training and feedback from trainees.

The facilitators created images of the results they want to achieve from the P3DM process in Tobago with Playdoh, yarn and pins.  They then created a storyboard for the video which will be developed to evaluate the effectiveness of P3DM in realizing these desired outputs.  The storyboard that was developed is a sequence of drawings which depict the shots planned for the video production.

Cassandra Mitchell of Grenada practices using
one of the PV video cams.

As part of the hands-on training, the participants took the cameras outside the building and took turns in learning how to operate them.

On Thursday 4th October, the facilitators will get ready to capture the workshop action on camera as community informants are expected to arrive in droves to ‘transpose their mental maps’ onto the blank model.

On a lighter note...

Though the trainers and experts themselves have been 'on the go' since the beginning of the workshop, they have found time for lighter moments, such as celebrating the birthday of Wellington Martinez from the Dominican Environmental Consortium.  Wellington had the joyful experience of having "Happy Birthday" sung to him in his native language, Spanish.  ¡Cumpleaños feliz, Wellington!"

Participatory mapping at CTA

Anne Legrosollard from Spore magazine interviews Giacomo Rambaldi, Sr. Programme Coordinator at CTA.

What is Participatory mapping?
What we support and promote at CTA goes beyond “making maps at community level”. We look at a practice dealing with generating, managing, analysing and communicating spatial information in a bottom-up mode. Mapmaking is considered as a step in a broader process leading to community empowerment by adding value and authority to local spatial knowledge.

How far can participatory mapping support decision-making ?
When it comes to accessing, using and / or managing natural resources, spatial dimensions always influence decision-making. Maps drawn in the sand on paper or on a computer screen are an accepted support to analysing spatially defined issues and getting the broader view which is essential in the process of making decisions. In addition maps are based on a visual language made of colours and symbols, thus are understandable also by illiterate people or less educated people.

What benefits can rural communities derive from the practice ?
The process leading to the production of maps is more important than the outputs themselves, as knowledge holders learn by doing. The process is quite motivating and often leads to stronger identity and cohesion among community members. On the top of that maps are powerful (and quite convincing) media which can be used to convey local concerns and aspirations to decision- and policy makers.

How do you ensure sustainability of the outcome of participatory mapping initiatives ?

Good practice recommends to perform participatory mapping activities only within the context of a long-lasting initiative having resources to continue beyond map-making. The map-making process raises the level of awareness among knowledge holders and with it their expectations and aspirations. It is a moral obligation of those accompanying the process to secure resources ensuring the continuation of the initiative to address new realities (positive and may be negative) which may emerge.

What should be done to prevent outsiders from appropriating themselves of the data generated during a participatory mapping exercise and to derive exclusive benefit from these ?
Good practice recommends that those assisting knowledge holders in the process are trusted intermediaries and that prior informed consent is obtained. Map making is a political process which can have positive or negative impacts. Drawing a line on a map may ignite conflict. How many wars have been fought over a line? Intermediaries facilitating map-making processes should be aware of these implication and operate at the highest ethical standards.  Being or not-being on a map is a trade-off. Nowadays if you are not on a map, you do not exist.

A Participatory Video made by Chivoko Village, Solomon Islands

Conservation Story Blong Chivoko" was made by the men and women of the remote coastal village of Chivoko, accessible only by sea on the north-west tip of Choiseul Island, one of the Solomon Islands. Chivoko's tribal land is one of the last remaining intact and unlogged forests in the Solomon islands. Their reefs are important spawning sites for the grouper fish which come to lay their eggs every year for 2 months around May. Their story is an insight into the problems they are facing with increased pressure from logging companies, increasing population, declining forest and marine resources, and ensuing climate change.

Mediating voices and communicating realities: Using information crowdsourcing tools, open data initiatives and digital media to support and protect the vulnerable and marginalised

This report published by IDS, investigates how the next generation of information and communication technologies (ICTs) — such as open mapping and open source crowdsourcing platforms — can empower vulnerable communities and build local capacity.

It is based on an investigation of how initiatives such as Map Kibera, an online community information source based in Kenya, contribute to creating shared information resources. The empirical data also provide insights into the hurdles and opportunities facing marginalised communities using these innovative communication tools. The report also presents results from interviews of leaders of ICT initiatives deployed to support post-reconstruction efforts in Haiti.

It outlines the challenges of using ICT for development, including the need to balance short-term individual benefits with longer-term agendas and the responsibility of those in charge to build trusting relationships to diffuse tensions emerging from free information sharing.

The study highlights the role of open-source social entrepreneurs as a new development actor, and the opportunities for collaboration between development and technology practitioners. The report suggests a follow-up research agenda to build upon this initial investigation.

The Manus MOSAIC - Participatory 3D modeling for climate change adaptation across Manus Province, Papua New Guinea

At the Manus Province Climate Change Seminar ‘Manus Way Forward’, October 2010, over 70 participants presented and shared experiences, expertise and ideas on how to adapt to climate change impacts. As part of the recommendations, representatives from the Provincial Government suggested using Participatory 3D modeling (P3DM) as a tool to help convene stakeholders and discuss province-wide responses to climate change impacts that would support and build on local efforts and scale-up impacts and opportunities.

In particular, the tool was proposed as a way to initiate discussion on a protected area network for Manus, the Manus ‘MOSAIC’. The exercise would be an initial step in outlining the spatial coverage of key ecosystem services, such as watersheds, reefs and mangroves, and representing and discussing opportunities for strengthened management of these areas under a future of climate change, and in the context of social and economic development for the province. The opportunity to involve local stakeholders from all LLG jurisdictions in this process will help develop a roadmap for the development of a Manus ‘MOSAIC’ protected area network.

Participatory 3D modelling

Participatory 3D modelling (P3DM) is a fully collaborative exercise that combines community mapping with open discussions on land-use and land-use planning scenarios.  It combines geographic precision with local, individual spatial knowledge and ‘mind-maps’ of locality and familiar settings.  During a P3DM exercise, all participants contribute to make a physical, hands-on wood-and paper model, to scale, of their community, island or area. This is typically made on a large table in the centre of a meeting hall, school or other public place. Once the model is made, then people become ‘resource persons’ and informants, and everyone will contribute to placing features and places onto the model. Key informants, such as elders and experienced fishermen or foresters, will offer their view of past events, of boundaries, of key localities and times for certain activities, and these can be discussed, and learned, by all participants.

Below is the video produced during the Solomon Islands event in February 2011.



In this way, the model is more than just a map, it is a representation of spatial knowledge of the participants, and a source of discussion and interpretation around key issues.

Although one key objective of this exercise is to plan for protection and restoration of key natural features, and to plan for possible climatic changes, other issues that are important to the province and the participating communities can be discussed in the same context. Furthermore, the model and the information can be used again, and again, for collaborative discussions and planning on key development issues. Digital GIS can be extracted from the model, and vice-versa, to aid and inform future discussions.  In this way, scientific information can be easily communicated and integrated with local knowledge and understanding.

Activity overview

The P3DM exercise will take place over a two-week period, from Monday 29th August to Friday 9th September. The first week will be dedicated to constructing the blank relief model, working closely with the local high-schools schools in Lorengau to allow students the opportunity to have a hands-on lesson in geography. It will also allow those participants interested in training / learning how to carry out a P3DM the opportunity to get involved.

The second week will concentrate on making the blank model come alive. Participants from all areas of Manus, and with all technical and local backgrounds, will discuss and add information to the model, including point data (features such as houses, schools, waterfalls, caves etc), line data (roads, streams, rivers, tracks, paths, boundaries, fences, cables, runways etc) and area data (polygons, such as mangroves, forest concession areas, reef flats, beaches, airports etc). Local knowledge on boundaries and features from participants from each part of Manus will contribute to an overall local picture of the province. Official and technical data can also be cross-referenced with local understanding, and represented on the model.

Towards the end of the second week, a facilitated discussion will focus on key issues, including ecosystem services and existing and proposed protected areas; current and proposed development activities (mining, forest concessions, urban and commercial expansion); and information related to predicted climate change impacts.

Future discussions on the proposed Manus MOSAIC protected area network can build on this initial analysis and use the 3D model for further participatory mapping.

General objectives of the Manus MOSAIC P3DM:

The P3DM exercise will enable all participants:

• To learn and understand Geographic Information Systems (GIS) in an open, hands-on and accessible way
• To participate in spatial planning for their own area as well as for the whole province
• To identify planned developments and trends in land-use change, and assessing the impacts of these changes on key ecosystem services
• To open a discussion on climate change impacts and how to integrate adaptation into spatial planning at local and provincial scales
• To discuss management and protection measures for key ecosystem services in the context of scaling-up beyond local efforts to ensure the best network of connectivity in conservation and adaptation efforts for the whole province

Groundbreaking Participatory Spatial Information Management and Communication Training Kit launched

The first ever training kit for Participatory Spatial Information Management and Communication was launched today after weeks of excited pre-ordering online. Co-published by CTA and IFAD, this training kit is a unique product that can be tailored to meet the learning needs of the individual, group or organisation.

‘This is a hugely exciting training tool for the development sector,’ commented Giacomo Rambaldi, Senior Programme Coordinator at CTA. ‘It means that employees can now get the best available training tailored to meet their individual needs.’

The training kit comprises 15 modules, each presented through a series of units. They cover the entire spectrum of good developmental practice. The modules deal with topics such as fundamentals of training, ethics and community groundwork and processes as well as the more technical low-, mid- and high-tech participatory mapping methods.

The Training Kit is featured on the CTA Publications catalogue. Available in English and Spanish, it is aimed at technology intermediaries working in multidisciplinary teams, and for those required to deliver training on the practice or facilitate the process in the field.

The benefits of this type of mapping are numerous. Mapmaking is considered as a step in a broader process resulting in community empowerment by adding value and authority to local spatial knowledge. The process leading to the production of maps is in fact more important than the outputs themselves, as knowledge holders learn by doing. The practice is motivating and often leads to stronger identity and cohesion among community members. Moreover, maps are a powerful and convincing medium which can be used to effectively convey local concerns and aspirations to decision- and policy makers.

This project is another example of CTA’s dedication to empowering rural communities through knowledge. The success of the training kit also demonstrates the benefits CTA enjoys through working with partners such as IFAD to deliver high quality information to a wider audience.

If you are interested in getting a copy of the Training Kit you may send an e-mail to Murielle Vandreck vandreck@cta.int adding PGIS-TK (English / Spanish) to the e-mail subject line.

Participatory 3-Dimensional Modelling: Guiding Principles and Applications; 2010 edition

The Technical Centre for Agricultural and Rural Cooperation ACP-EU (CTA) recently released a new edition of the handbook "Participatory 3D Modelling: Guiding Principles and Applications; 2010 Edition”. The Global Environment Facility (GEF) Small Grants Programme (SGP) supported its French and Spanish versioning. The documents are now available in three languages as free downloads at high and medium resolutions.
Participatory three-dimensional modelling (P3DM) is a participatory mapping method integrating indigenous spatial knowledge with data on elevation of the land and depth of the sea to produce stand-alone, scaled and geo-referenced 3D models. Essentially based on recollections from memory, land use and cover and other features are depicted by informants on the model by using push pins for points, yarns for lines and paints for polygons. On completion, a scaled and geo-referenced grid is applied to facilitate data extraction or importation. Data depicted on the model are extracted, digitised and plotted. On completion of the mapping exercise, the model remains with the community.

P3DM has been conceived as a method for bringing the potential of GIS closer to rural communities and for bridging the gap that exists between geographic information technologies and capacities found among marginalised and isolated communities who are frequently dependent on natural resources.

This handbook is intended to assist activists, researchers and practitioners of participatory learning and action (PLA) and GIS in bringing the power of GIS to the grassroots level through the use of P3DM. It provides hands-on guidelines on how to organise and implement a P3DM exercise. In addition it includes insights on adult learning and spatial cognition, on the history of relief models and on the use of the method around the world.


On 5 November 2007, P3DM was granted the World Summit Award 2007 in the category of e-culture. P3DM was considered to be one of the 40 best practice examples of quality e-content in the world.

Localisation, Participation and Communication: an Introduction to Good PGIS Practice

Localisation, Participation and Communication: an Introduction to Good PGIS Practice from Giacomo Rambaldi on Vimeo.

This 25-min educational video documentary introduces the practice of participatory spatial information management and communication (PGIS) in the development context. It has been designed to introduce development practitioners (technology intermediaries) to the practice of demand-driven PGIS.

In this video, PGIS practice is presented as a continuum starting from community mobilisation to project planning and design, choice of mapping methods and technologies, visualisation of different technologies in diverse ethno-cultural and agro-ecological environments, and finally putting the maps to work in the domains of identity building, self-determination, spatial planning and advocacy.

Ethics and sound attitudes and behaviours are emphasized as cross-cutting imperatives.
