‘We are our land’— Ogiek of Mount Elgon, Kenya: securing community tenure as the key enabling condition for sustaining community lands

Published in Oryx – the international journal of conservation – this open access article also highlights how this community control is under constant threat until and unless national law and practice recognizes the collective tenure rights of such communities.

"We outline how securing the community tenure rights of forest peoples can create a rapid, rights-based route to the effective and sustainable conservation of their forests. We draw on the different skillsets and experiences of the authors (long-term fieldwork, mapping and monitoring, and a lifetime of experience) to identify the conditions that enable the Ogiek of Chepkitale, Mount Elgon, Kenya, to sustain and be sustained by their lands. 

We also identify the conditions that drive the disruption of this sustainable relationship through an appropriation of Ogiek resources by external interests that threaten to degrade, alienate and destroy their ecosystem. It is increasingly recognized that securing sustainable conservation outcomes can be best achieved through the deep knowledge, connection and commitment that ancestral communities have regarding their lands. 

Evidence from Mount Elgon and more broadly shows that Indigenous Peoples are better guardians of their forests than international or state protection agencies. This challenges the idea that evicting forest peoples is the best way to protect forests. Other studies, including those conducted by the Kenyan governmental Taskforce on Illegal Logging, highlight the way Kenyan state agencies such as the Kenya Forest Service have been responsible for the severe depletion of Indigenous forests. 

We examine how de facto collective community control can enable decisions to be made in line with taking care of community lands over the long term, but also highlight how this ability is under constant threat until and unless national law and practice recognizes the collective tenure rights of such communities."

Evaluating Participatory Mapping Software

Evaluating Participatory Mapping provides a framework for evaluating geospatial software for participatory mapping. The evaluation is based on ten key indicators: ethics, cost, technical level, inclusiveness, data accuracy, data privacy, analytical capacity, visualization capacity, openness, and accessibility (i.e., mobile friendly or offline capabilities). 

Each application is evaluated by a user and cross analyzed with specific case studies of the software’s real-world application. This framework does not discriminate against assessing volunteered geographic information (VGI) applications, as a form of participatory mapping, in circumstances that its application is spearheaded by underrepresented groups with the intent to empower and spark political or behavioral change within formal and informal institutions. 

Each chapter follows a strict template to ensure that the information within the volume can be updated periodically to match the ever-changing technological environment. 

The book covers ten different mapping applications with the goal of creating a comparative evaluation framework that can be easily interpreted by convening institutions and novice users. 

This will also help identify gaps in software for participatory mapping which will help to inform application development in the future and updates to current geospatial software.

Managing Natural Resource Conflicts with Participatory Mapping and PGIS Applications (English Edition)

This book integrates spatial analysis into the study and management of conflicts, and offers a model in conflict studies that incorporates theoretical explanations of conflict, its causes, and impacts, with a geospatial strategy for intervening in disputes over allocation and use of natural resources (connects theory and practice). Alongside a theoretical analysis of resource conflicts and an account of Participatory Mapping and PGIS development, this book provides a case study of GIS applications in conflict mediation. 

The book also lays out a practical and straightforward demonstration of PGIS applications in conflict management using a real-world case study, and traces the Participatory Mapping and PGIS movements evolution, compares PPGIS and PGIS practices, and makes distinctions between traditional GIS applications and PGIS practice. The approach embodies the enhanced use of spatial information and media, sets of tools for analysing, mapping, and displaying spatial data and a platform for participatory discussions that enhances consensus-building. 

The book, therefore, contributes to the search for novel approaches for managing current and emerging conflicts. With this book, resource managers, development practitioners, students, and scholars of Participatory Mapping and PGIS applications and conflict studies will be equipped with the principles, skills, and the tools they need to manage non-violent resource conflicts and keep the disputes from slipping into violence. The book will also be a valuable text for basic and advanced studies in Participatory Mapping and PGIS applications, Conflict Resolution and Conflict Management.

Préparer un avenir meilleur

Les personnes qui ont un faible niveau d’éducation et d’alphabétisation ont du mal à se faire entendre. C’est particulièrement vrai pour les communautés autochtones. Leurs connaissances ancestrales et leurs droits sont souvent ignorés par les gouvernements, les sociétés d’exploitation de minerais et d’autres qui souhaitent exploiter leurs terres. Toutefois, cette situation n’est pas inéluctable. En collaborant avec des partenaires locaux, le CTA a contribué à faire d’eux des pionniers dans un processus – baptisé Modélisation participative en 3D – qui aide les communautés locales à documenter les régions dans lesquelles elles vivent, mais également à influencer la façon dont les décisions sont prises concernant l’utilisation et l’occupation des sols.

 «Traditionnellement, les cartes étaient réalisées par les gouvernements, qui contrôlaient également les données», explique Giacomo Rambaldi du CTA. «Mais un énorme changement a eu lieu récemment, à mesure que les groupes de la société civile ont acquis la capacité de réaliser leurs propres cartes et vidéos.» Ils ont bénéficié de l’accès à Google Earth et YouTube ainsi qu’à la modélisation participative en 3D, qui leur ont permis de créer des cartes exactes et géo-référencées.

Le premier exercice de modélisation soutenu par le CTA dans le Pacifique a eu lieu aux Fidji, en 2005. Cet événement de 11 jours à Lavuka s’est concentré sur l’île d’Ovalau, où les communautés locales souffraient d’une surexploitation de leurs zones de pêche, en particulier par des flottes étrangères. Au cours des trois premiers jours, trente étudiants de l’enseignement supérieur et six enseignants ont créé un modèle en 3D de l’île avec l’aide de quinze animateurs et stagiaires. Quatre-vingt-dix hommes et femmes de 26 villages ont ensuite «peuplé » le modèle de montagnes, de routes, de rivières, de zones de pêches, de terres agricoles, de sites culturels et d’autres caractéristiques. Lorsqu’ils ont eu terminé, le modèle comptait 79 caractéristiques et 83 lieux revêtant une importance culturelle.

Le modèle a ensuite servi de base pour un plan de gestion à l’échelle de l’île et trois plans de gestion de districts. Le processus a identifié seize zones «taboues » dans lesquelles une protection complète de la faune marine est à présent assurée. Les autochtones ont également commencé à dégager des parcours cérémonieux qui avaient été envahis par la végétation. En trois années de recherche, le Musée des Fidji n’avait réussi à identifier que vingt lieux revêtant une importance culturelle – soit un quart du nombre de lieux identifiés par les villageois pendant le processus de modélisation.

À bien des égards, le processus est aussi important que le résultat obtenu. «Il aide les gens à visualiser et à localiser leurs connaissances spatiales, ce qui est très motivant », explique Giacomo Rambaldi. « Et, bien sûr, il leur permet de défendre leur cause de façon plus persuasive. » Dans le passé, les communautés autochtones pouvaient produire des croquis cartographiques en faisant valoir des revendications pour leurs terres, mais les décideurs n’en tenaient guère compte. Les modèles en 3D fournissant des détails complexes sur les caractéristiques du paysage sont beaucoup plus difficiles à ignorer.

À travers le Pacifique

Kenn Mondiai, qui dirige l’ONG «Partners with Melanesians », basée en Papouasie-Nouvelle-Guinée, fait partie des qui bénéficiaires d’une formation aux Fidji. Depuis lors, il a joué un rôle important dans la promotion de la modélisation participative en 3D à travers le Pacifique. Avec le soutien de la Banque mondiale, il a aidé les communautés locales du Plateau de Managalas en Papouasie-Nouvelle-Guinée, qui abrite 150 clans, à créer un modèle en 3D de leurs terres ancestrales. Ce modèle a servi comme élément de preuve pour promouvoir la Zone patrimoniale de Managalas (Managalas Conservation Area), dont la reconnaissance officielle est prévue au moment de la mise sous presse.

En 2011, l’organisation de protection de l’environnement The Nature Conservancy a engagé Kenn Mondiai afin de diriger des formations dans les îles Salomon. Les exercices de modélisation dans le village côtier de Boe Boe se sont concentrés sur le changement climatique et ses répercussions possibles. Le modèle présentait l’étendue du dernier tsunami en 2007 et le niveau des récentes marées hautes qui avaient inondé certaines parties du village. La communauté a ensuite utilisé le modèle pour discuter de l’impact potentiel de la hausse du niveau des mers et d’autres événements liés au climat.

« Le modèle a montré à la jeune génération que nous devions réfléchir au changement climatique », a fait remarquer Winifred Piatamama après l’exercice. «Il est important de prendre conscience que, dans quelques années, le niveau de la mer ne sera pas le même qu’aujourd’hui. » Après avoir débattu, les villageois ont décidé qu’au lieu de construire le long de la côte, comme ils l’avaient fait jusqu’à présent, ils se tourneraient vers les terres plus élevées, à l’écart de la mer. En résumé, le modèle les a aidés à concevoir des plans qui les aideront à s’adapter au changement climatique.

Selon Winifred Piatamama, le processus de modélisation a été particulièrement important pour les femmes de la communauté. « Au début, c’était un peu difficile pour les femmes, parce qu’elles n’expriment pas leurs préoccupations, elles sont généralement silencieuses », a-t-elle déclaré. Toutefois, le processus de modélisation les a encouragées à faire part de leurs points de vue plus ouvertement. « Lorsque tous contribuent au modèle, ils partagent fierté et propriété », explique Gabriel Kulwaum, de l’organisation TNC (The Nature Conservancy) dans un petit film sur l’exercice de Boe Boe. « Ce n’est pas TNC ou le gouvernement qui en a la propriété. » C’est la communauté.

Formation aux Caraïbes

Le CTA était très désireux d’encourager une modélisation participative en 3D dans les Caraïbes, mais était obligé d’importer l’expertise d’ailleurs. En octobre 2012, le premier exercice de modélisation a eu lieu à Tobago, sous l’égide de l’Institut des ressources naturelles des Caraïbes (Caribbean Natural Resources Institute, Canari) et animé par Kenn Mondiai. Cela a donné lieu à des ateliers de suivi de modélisation sur l’île de l’Union et à la Grenade.

Pour Gillian Stanislaus, du ministère des Ressources naturelles et de l’environnement de Trinidad-et-Tobago, le modèle en 3D de Tobago aidera les autorités à gérer plus efficacement les futurs développements. « Grâce au processus de modélisation, nous avons une connaissance bien plus approfondie de la façon dont les terres sont utilisées et de leur importance pour les habitants », affirme-t-elle.

Terrence Phillips a participé à l’un des ateliers de modélisation – qui portait sur l’adaptation au changement climatique – en tant que représentant du Mécanisme régional des pêches des Caraïbes. Il a été impressionné. « Je pense qu’il s’agit d’un outil très utile », confie-t-il. « Les communautés étaient en mesure de décrire ce qui était arrivé à leurs ressources maritimes dans le passé et l’état des ressources à l’heure actuelle. » La modélisation les a encouragées à prendre en considération l’impact éventuel de la hausse du niveau des mers et du changement climatique et à concevoir des stratégies d’adaptation. L’exercice de modélisation a contribué à l’instauration d’un dialogue constructif entre le gouvernement et la communauté locale, garantissant leur collaboration efficace à l’avenir.

La première en Afrique

L’organisation du premier exercice participatif de cartographie en 3D en Afrique a pris 10 mois. Cet exercice, qui s’est tenu dans le village de Nessuit, dans le comté de Nakuru au Kenya, était géré par Systèmes de cartographie et d’information en recherche environnementale en Afrique (Environmental Research Mapping and Information Systems in Africa, ERMIS-Africa), avec le soutien financier et technique du CTA. Pendant 11 jours, en août 2006, quelque 120 hommes et femmes appartenant à 21 clans Ogiek ont construit un modèle en 3D du complexe oriental de la forêt de Mau.


The Voice of the Ogiek from CTA on Vimeo.

La forêt de Mau a souffert pendant des décennies de l’exploitation commerciale et de l’envahissement par des cultures. Ces activités ont détruit une grande partie du paysage ainsi que bon nombre de sites culturels ogiek et, pendant quelques années, les Ogiek ont tenté de faire valoir en justice leurs droits sur ces terres. « Les procédures juridiques traînaient en longueur, sans aucune solution véritable », déplore Julius Muchemi, directeur d’ERMIS-Africa. « Ce dont les Ogiek avaient besoin, c’était de preuves concrètes venant soutenir leurs revendications ; et l’exercice de modélisation les a aidés à fournir ces preuves. »

Les preuves ont été suffisamment persuasives pour convaincre le gouvernement du droit des Ogiek sur les terres et de la nécessité de protéger la région de nouvelles dégradations. Lorsqu’un processus de préservation a été lancé en 2007, tous ceux qui occupaient la forêt en dehors des Ogiek ont été expulsés. Depuis lors, ERMIS-Africa et ses partenaires ont produit l’Atlas des territoires ancestraux des peuples Ogiek (Ogiek Peoples Ancestral Territories Atlas). Cet atlas présente la description la plus détaillée à ce jour de la culture Ogiek et de leurs liens avec la terre.

Parmi les organisations qui ont soutenu l’exercice de cartographie, citons le Comité de coordination des peuples autochtones d’Afrique (Indigenous Peoples of Africa Coordinating Committee, Ipac). Selon son directeur, Nigel Crawhall, il s’agit d’un événement majeur dans la vie de l’IPacC. L’exercice de cartographie et le soutien apporté par le CTA à l’organisation ont mené à une série de développements importants pour le peuple autochtone, et notamment à l’engagement de l’IPacC à la Convention-cadre des Nations unies sur les changements climatiques et le lancement d’un programme de formation multinational sur l’atténuation et l’adaptation au changement climatique.

Dans une synthèse écrite concernant l’impact du CTA, le Dr Crawhall a expliqué : « D’un point de vue professionnel, les relations avec le CTA ont apporté d’importants changements, de nouveaux outils et opportunités [...] L’exposition et le partenariat avec le CTA ont transformé le travail, les pratiques et les connaissances du seul réseau régional des peuples autochtones d’Afrique, exercé une incidence sur la vie des personnes dans plus d’une douzaine de pays et créé de nouvelles opportunités de carrière et de sensibilisation pour les leaders autochtones et m’ont ouvert de nouveaux horizons sur le plan professionnel. »

Depuis l’exercice de cartographie de la forêt de Mau, le CTA a soutenu des initiatives similaires en Éthiopie, au Gabon, au Tchad et en Ouganda. Soutenus par un manuel électronique publié en anglais, en français, en espagnol, en portugais et en amharique, ainsi que par une communauté en ligne dynamique, des exercices de modélisation ont également eu lieu dans d’autres parties du Kenya, au Ghana, au Maroc et en République démocratique du Congo et de nombreux autres pays, comme indiqué sur la carte ci-dessous.

Modelling a brighter future

People with low levels of education and poor literacy skills have difficulty making themselves heard. This is particularly true for indigenous communities. Their ancestral knowledge and rights are often ignored by governments, mineral companies and others who wish to exploit their lands. However, it needn’t be like this. Working with local partners, CTA has helped to pioneer a process, known as Participatory 3-D Modelling, which is helping local communities not only to document the areas where they live, but influence the way decisions are made about land-use and tenure.

“Traditionally, maps were made by governments, and the data was controlled by governments,” says CTA’s Giacomo Rambaldi. “But there has been a huge change recently as civil society groups have acquired the ability to make their own maps and videos.” They have benefited from access to Google Earth and YouTube and participatory 3-D modelling as a way of creating accurate, geo-referenced maps.

The first CTA-supported modelling exercise in the Pacific was held in Fiji in 2005. The 11-day event in Lavuka focused on Ovalau Island, where local communities were suffering from the over-exploitation of their fishery grounds, especially by foreign fleets. During the first three days, 30 high-school students and six teachers constructed a 3-D model of the island with the assistance of 15 facilitators and trainees. Ninety men and women from 26 villages then ‘populated’ the model with mountains, roads, rivers, fishing grounds, croplands, cultural sites and other features. By the time they had finished, the model had 79 features and 83 places of cultural significance.

The model was subsequently used as a basis for an island-wide management plan and three districts management plans. The process identified 16 ‘taboo’ areas in which there is now total protection of marine life. Local people have also begun to clear ceremonial pathways which had become overgrown. During the course of three years of research, the Museum of Fiji only managed to identified 20 places of cultural significance – a quarter of the number identified by villagers during the modelling process.

In many ways, the process is as important as the finished article. “It helps people to visualise and localise their spatial knowledge, and this is very empowering,” says Giacomo. “And, of course, it enables them to make their case more persuasively.” In the past, indigenous communities might produce sketch maps laying claims to their land, but decisions-makers seldom took much notice. The 3-D models providing intricate details of landscape features and resource use are much harder to ignore.

Across the Pacific


Kenn Mondiai, who runs Partners with Melanesians, an NGO based in Papua New Guinea, was among those to benefit from training in Fiji. Since then he has played an important role in promoting participatory 3-D modelling across the Pacific. With support from the World Bank, he helped local communities on PNG’s Managalas Plateau, home to around 150 clans, to create a 3-D model of their ancestral lands. This was used as part of the evidence to promote Managalas Conservation Area, whose official recognition is anticipated around the time of going to press.

In 2011, The Nature Conservancy hired Kenn to conduct trainings in the Solomon Islands. The modelling exercise at the coastal village of Boe Boe focused on climate change and its possible impact. The model showed the extent of the last tsunami in 2007 and recent king-tide levels that had inundated parts of the village. The community then used the model to discuss the potential impact of rises in sea-level and other climate-related events.

“The model showed the younger generation that we need to think about climate change,” reflected Winifred Piatamama after the exercise. “It’s important to realise that in a few years time the sea level won’t be the same as it is now.” Following discussions, the villagers decided that instead of building along the coastline, as they have done in the past, they would look towards the higher land further from the sea. In short, the model helped them to devise plans which will help them adapt to climate change.

According to Winifred, the modelling process was particularly important for the women in the community. “At the beginning it was a bit challenging for women, because they don’t raise their concerns, they are generally quiet,” she said. However, the modelling process encouraged them to share their views more openly. “When everyone contributes to the model, they share pride and ownership,” reflected Gabriel Kulwaum of The Nature Conservancy (TNC) in a short film about the Boe Boe exercise. “TNC or the government don’t own it.” The community does.

Training in the Caribbean


CTA was keen to encourage participatory 3-D modelling in the Caribbean, but was obliged to import expertise from elsewhere. In October 2012, the first Caribbean modelling exercise was held in Tobago, hosted by the Caribbean Natural Resources Institute (CANARI) and facilitated by Kenn Mondiai. This led to follow-up modelling workshops on Union Island and Granada.

According to Gillian Stanislaus of the Department of Natural Resources and Environment in Trinidad and Tobago, the Tobago 3-D model will help the authorities manage future developments more efficiently. “Because of the modelling process, we have a much greater depth of knowledge about the way in which the land is used and its significance for local people,” she says.

Terrence Phillips attended one of the modelling workshops – its focus was on adapting to climate change – as a representative of the Caribbean Regional Fisheries Mechanism. He was impressed. “I think this is a very useful tool,” he says. “The communities were able to describe what had happened to their marine resources in the past and the state of the resources now.” The modelling encouraged them to consider the possible impact of sea-level rises and climate change, and devise strategies to help them adapt. The modelling exercise helped to create a constructive dialogue between the government and the local community, ensuring that they work together effectively in future.

Africa's first


Africa’s first participatory 3-D mapping exercise took some 10 months to organise. Held in the village of Nessuit in Kenya’s Nakuru County, it was managed by Environmental Research Mapping and Information Systems in Africa (ERMIS-Africa), with financial and technical support from CTA. Over the course of 11 days in August 2006, some 120 men and women belonging to 21 Ogiek clans constructed a 3-D model of the Eastern Mau Forest Complex.

The Mau Forest had suffered from decades of commercial logging and encroachment. These activities had destroyed much of the landscape, as well as many Ogiek cultural sites, and for some years the Ogiek had been attempting to assert their rights to the land in court. “The court cases had been dragging on, with no real resolution,” explains Julius Muchemi, director of ERMIS-Africa. “What the Ogiek needed was concrete evidence to support their claims, and the modelling exercise helped to provide that.”

The evidence was persuasive enough to convince the government of the Ogiek’s right to the land, and the need to protect the area from further degradation. When a conservation process was launched in 2007, all those occupying the forest apart from the Ogiek were evicted. Since then, ERMIS-Africa and its partners have produced the Ogiek Peoples Ancestral Territories Atlas. This provides the most comprehensive description to date about the Ogiek’s culture and their links to the land.

Among the organisations which supported the mapping exercise was the Indigenous Peoples of Africa Coordinating Committee (IPACC). According to its director, Nigel Crawhall, this was a key event in the life of IPACC. The mapping exercise, and CTA’s support for the organisation, led to a series of important developments for indigenous people, including IPACC’s engagement with the UN Framework Convention on Climate Change and the launching of a multi-country training programme on climate change mitigation and adaptation.

“From a professional perspective,” said Dr Crawhall, in a written summary about the impact of CTA, “the relationship with CTA has brought important changes, new tools and opportunities... Exposure and partnering with CTA has transformed the work, practice and knowledge of Africa’s only regional indigenous peoples network, it has touched the lives of people in more than a dozen countries, it has created new career and advocacy opportunities for indigenous leaders, and it has opened new horizons for me professionally.”

Since the Mau Forest mapping exercise, CTA has supported similar initiatives in Ethiopia, Gabon, Chad and Uganda. Supported by an e-handbook published in English, French, Spanish, Portuguese and Amharic, and a vibrant online community, modelling exercises have also taken place in other parts of Kenya, the Democratic Republic of Congo, Ghana and Morocco and many other countries as shown on the map below.

Participatory 3D Modelling in Western Samoa triggers behavioural changes and climate change resilience

Since 2012 the local government together with local communities in Western Samoa have carried out a total of 19 participatory 3D modelling (P3DM) exercises in the context of agroforestry management, water management and tourism development.

A participatory research was conducted between February and April 2016 to explore the effectiveness and potential of P3DM in the region. The study was done by Barbara Dovarch, PhD candidate at the Department of Architecture Design and Urban Planning, University of Sassari, Italy, sociologist and independent researcher, in partnership with the Technical Centre for Agricultural and Rural Cooperation (CTA) and Samoa’s Ministry of Natural Resources and Environment (MNRE).

This participatory impact evaluation involved diverse members of local communities and MNRE technical staff. It focused particularly on the capacity of P3DM to generate deep-seated and long-lasting behavioural changes.

The results of the study demonstrates that P3DM contributes to natural resource management and climate change resilience and showed the transformative power of the process at various levels, such as community, NGO and governmental level.

Through the P3DM process, meaningful interactions between government representatives and community members resulted in greater collaboration and mutual learning. While government representatives have changed the way they approach local communities – from ‘teaching’ to ‘listening’ – communities have also changed their attitude towards land management and development.

Participatory 3D modelling as a socially engaging approach in ecosystem service assessments among marginalized communities

Land use decision making in the Suriname Upper Suriname River area knows a history of dis-
empowerment and marginalization of the Saamaka communities inhabiting the area. Non-recognition of land rights is at the origin of this problem. This is aggravated by the increasing over-exploitation of timber resources by powerful stakeholders and the unfair distribution of timber benefits. This has left Saamakans marginalized, causing distrust and opposition among themselves and towards outsiders. Furthermore, as a result of deforestation, Saamakans face detrimental changes in the ecosystem services (ES) that support their traditional livelihoods, with important effects for their well-being.

This environment of distrust, opposition and marginalization makes it difficult to assess these concerns. Hence, an ES assessment approach that would generate salient ES knowledge while generating trust, communication among stakeholders and local capacity building was needed. In this paper we evaluate whether Participatory 3D modelling (P3DM) is an effective approach for ecosystem services assessments in such disabling environments. We evaluate this by using empirical data from an ES assessment in the Saamaka region using a P3DM approach. Results show the efficient identification and evaluation of 36 ES representing provisioning, cultural and regulating service categories with crops, fish, wild meat, timber and forest medicines identified as most important.

The authors of this paper found a decrease in the demand and supply of crops, fish and wild meat associated with ecosystem degradation, out-migration and changes in lifestyles. Further, the findings of the research show an increasing demand and decreasing supply for timber related to over-exploitation. The research provided evidence of the usefulness of P3DM to foster multi-functional landscape development among a range of communities.

In the paper the authors discuss the usefulness of the approach and the conditions needed for the P3DM process to address the needs of the local communities as well as the need for a broader P3DM implementation strategy beyond the engagement, screening, and diagnostic phases of ES assessments when the aim is to enhance ES outcomes for marginalized communities.

Mapping local knowledge to drive sustainable natural resource management, influence policy-making and promote climate change adaptation

A new publication from the Technical Centre for Agricultural and Rural Cooperation (CTA) illustrates how local communities in a range of developing countries have developed a bird’s-eye perspective of their land and water resources through Participatory 3D modelling (P3DM). This innovative technique is proving a valuable tool for often voiceless groups, helping them to manage and protect their habitats, influence decision-making and take control of their future.

Improving natural resource management, mapping community rights and bolstering climate change adaptation – participatory 3D modelling can help to do all this and more. Developed in the early 1990s in Southeast Asia, the technique offers communities a tangible way of visualising tacit knowledge, producing stand-alone relief models that depict natural surroundings, but also cultural information, helping groups to assert their rights and protect their traditional knowledge from outside exploitation.

CTA has been in the forefront of P3DM development in African, Caribbean and Pacific countries, launching it in Fiji, Gabon, Kenya and Trinidad and Tobago, and helping to foster South-South cooperation to spread the practice further afield. The Power of Maps: Bringing the Third Dimension to the Negotiation Table documents some of the achievements obtained so far. All twelve of the case studies presented show how the process of building 3D maps has led to positive changes.

“Traditional knowledge is gaining recognition at the international level, but at the local level, government officials and technocrats tend to dismiss it as anecdotal and scientifically unproven,” said CTA P3DM expert and Senior Programme Coordinator ICT Giacomo Rambaldi. “The process documented in this book enables knowledge holders to visualise and georeference their traditional knowledge and to engage outsiders in a peer-to-peer dialogue.

Building a P3DM model generally involves the entire community, with the elders supplying their traditional knowledge and children taking charge of the actual construction, using cardboard, paints, pushpins and yarn. An important part of the exercise is the way it brings generations together, giving value to the contributions of each and making people feel a sense of pride – in their surroundings and heritage and in the map itself.

On the Pacific island of Ovalau, a P3DM initiative led farmers and fishers to adopt more sustainable land use and fisheries practices, with significant increases in production as a result. Impacts included a doubling of fish stocks, a sizeable increase in crop output and a rise in the number of tourists visiting the island. In Madagascar, the creation of a 3D map drew an initially sceptical community into a watershed planning process, with people quickly seeing the benefits in terms of improved resource management and income generation.

Members of a pygmy community displaced to make way for a protected area in the Democratic Republic of Congo used the web of knowledge displayed on their 3D map to regain access to traditional lands and claim a role in managing them. Meanwhile, in Kenya, a three-dimensional mapping exercise helped the Ogiek tribe to document its ancestral land rights and knowledge systems, with far-reaching repercussions – including shaping government policy on indigenous peoples.

Climate change poses a special threat to vulnerable small island states, and on the Caribbean island of Tobago, P3DM has been used to guide community driven disaster risk reduction strategies. In another three-dimensional mapping exercise in the region, the experience of building a climate risk map of Grenada has produced the added spin-off of strengthening the capacity and professional networks of local organisations. One unexpected outcome has been the signing of an international partnership to fund the replanting of mangroves, as part of an ecosystem management strategy to protect the island from persistent hurricanes that are endangering lives and livelihoods.

Mapping deep in the jungle: our experience among Saramaccan Peoples

In July 2015 local residents and leaders from 14 indigenous Saramaccan villages, located along the upper Suriname River, collaborated with local and international NGOs to create a physical 3D representation of their traditional land and waters using participatory three-dimensional modelling (P3DM). The mapped area is sparsely populated and characterised by externally-driven logging and mining activities. The mapping process, provided participants with a comprehensive and detailed understanding of the landscape, its interlocked ecosystems, and potential impacts of road development and related extractive activities. This enabled them to formulate informed opinions on how best to develop, preserve and manage the traditional territories.

The process has highlighted how effective P3DM is when it comes to bottom-up and inclusive landscape planning. Helping communities to build a 3D model of their territory is proving to be an effective way for knowledge held by different individuals to be collated, geo-referenced and visualised, thus generating a powerful pool of data mostly unknown to the outside world. If strategically used, this data could shift the balance of power in favour of those who would otherwise not be included in decision-making processes.

The blog below was written by Nicholas Fields (INTASAVE Caribbean/CARIBSAVE) and Gaitrie Satnarain (CARIBSAVE Associate at the Anton de Kom University of Suriname).

CARIBSAVE was invited by Tropenbos International Suriname (TBI) and CTA to participate in a Participatory three-dimensional modelling (P3DM) exercise, conducted on 21–31 July 2015, as part of the above-mentioned project. Our group included representatives from TBI (including persons of Saramaccan origin), students and staff from the Anton de Kom University of Suriname, and ourselves – representing CARIBSAVE. Sponsored by CTA, our participation in the exercise helped us to understand and appreciate the P3DM process and now enables us to replicate it within our own projects in the Caribbean region. It is our intention to share what we have learned with our colleagues and build capacity within our own organisation.

What is P3DM?

P3DM is an inclusive process of building a physical 3D model of a specific area that details how communities use the natural environment – has demonstrated its significance and practicality beyond rudimentary research and data collection purposes. P3DM has proved to be an effective tool for bringing a diverse group of stakeholders, including representatives from the villages, community-based and non-governmental organisations, technical people and policy-makers, to the table to exchange ideas, perspectives and information; strengthen and build new relationships; support decision-making related to land use; and re-invigorate a desire to protect the environment and to use our resources sustainably for the benefit of current and coming generations.

A long journey to a remote location

On the first day we travelled three hours by bus followed by two hours by canoe to the Saramaccan village of Pikin Slee (which means ‘small village’ – although it is, ironically, one of the most inhabited and visited villages in the Upper Suriname basin) and the neighbouring ecolodge, Pasensie. From the river, the village does look deceptively small, but on traversing inland you can see that the landscape is dotted with variously sized dwellings used for domestic and communal activities. Saramaccan way of life is modest, with irregular access to amenities that one would have in the city (with the exception of smartphone/mobile devices, which are abundant).

Mapping the environment

We were warmly welcomed by the villagers upon arrival. The next five days were extremely busy assembling the blank model – that is a plain, white, three-dimensional canvas prior to any painting, drawing or pinning. The blank canvas is comprised of stacked layers of foam board material, with each layer representing an altitude interval, and shaped according to the specific altitude contour. The result is a scaled and geo-referenced three-dimensional canvas of hills, valleys, plains and depressions of the real-life landscape. The actual size of the area modelled was approximately 2,232 km2 and, with a horizontal scale of 1:15,000, the model developed into a rather large construction, involving five tables of approximately 1.6 x 1.2 m each.

Model construction is exciting as well as intensive, and the teenagers from a village-based school who took part in this process would certainly agree on this! The facilitators helped the students to trace each contour onto the foam boards, cutting these accordingly and affixing each layer of board to the model. Once the foam boards were cut according to the contours and stacked, the model was covered with plaster to allow for painting, which is perhaps the most labour-intensive component of the process, requiring precision, accuracy and careful attention to detail. The team had some initial challenges with matching and/or aligning contour maps, foam board pieces and uneven table tops, as well as working with the foam board itself. Understanding the nature of the problems, considering possible corrections and subsequent improvement was an important part of the learning process.

Mapping the knowledge

The next phase of the exercise, which took another 4–4½ days, involved populating the blank model with data on land cover and use (e.g. forests, agricultural land), locations of villages and estimated populations, and types and locations of activities associated with the villages and their inhabitants. The map legend – outlining what features would be located and visualised on the model – was finalised beforehand by the facilitators and representatives from the different villages located within the modelled area.

This stage was the most crucial and sensitive. Local residents and leaders had full autonomy entering data on the model at this point. This helped building buy-in and ownership of the process by the villagers, and minimising interference or perception of bias by the facilitators. Local residents spearheaded the process of identifying and marking features, place names and locations of activities. The facilitators (mainly the TBI team members of Saramaccan origin) offered only moderate guidance, taking care not to influence the direction of discussion except in the interest of maintaining consistency in the use of legend items, scale, focus and time, or mediating diverging opinions when these arose. Only agreed data were placed on the model. Specific locations and activities of cultural, spiritual or – in some cases – economic significance were not visualised, in the locals’ interest of protecting their security and inviolability.



Despite the fact that locals were given autonomy at this stage, some of them were distrustful of the process, fearing possible coercion, exploitation and vested interests by outsiders. The presence and interaction of the Saramaccan facilitators in the TBI team helped to alleviate most of these fears. Still, it was intriguing to observe the sometimes animated dialogue between locals as they detailed various parts of the model – indicating primary and secondary forest areas, tracks and paths, and places of work, domestic and recreational use.

We learned a lot there by observing and implementing the P3DM activity. And the strong multi-cultural element added another dimension. The indigenous Maroon groups were working with their own set of norms, practices and structures, which were very different to those that the external facilitators were used to. Including the participants and facilitators, the 10-day exercise brought together people of at least five nationalities and ethnic groups. At any given time during the activities, there were at least three languages at play: chief of these being Saramaccan, Dutch and English, with intercessions in Spanish and Arkans. While there were some slight communication barriers, none was too difficult to overcome – in fact, this made the experience much more amusing, and there were several side-lessons in foreign language vocabulary. There is no doubt that the group of facilitators also learned much over the two weeks, and established new personal and working relationships to build on in the future.

This P3DM exercise took dedication and was a large undertaking. Significant time and resources were required to co-ordinate and complete the model, particularly when the diversity of players and relative remoteness of the beneficiary groups are taken into consideration. However, the benefits of the exercise – first-hand participation in P3DM, learning and exchanging new information, connecting with people and building new rapports – were outstanding and will be long-lasting. The students’ participation also played an important educational role. We hope that they were able to appreciate the purpose of the model and will take forward what they learned from this process as they become leaders in the future.

Further impact: applying the knowledge gained

Since taking part in the exercise, CARIBSAVE has incorporated the P3DM methodology into one of its project proposals. It is planning to use the P3DM methodology for a participatory flooding hazard mapping and zoning exercise, as part of a larger comprehensive disaster management initiative. Through this exercise, community residents would produce a model that details flooding risk areas, vulnerable persons, infrastructure and emergency facilities as the basis for developing a community response plan.

Gaitrie Satnarain from Anton de Kom University intends to further what she has gained from the exercise by incorporating P3DM as a research tool within her upcoming doctoral study proposal. At the Anton de Kom University of Suriname, the Infrastructure Department in the Faculty of Science and Technology will also discuss potential opportunities with TBI to incorporate and promote P3DM for landscape planning research. CARIBSAVE will continue to explore and incorporate the P3DM methodology into its future projects to support building knowledge and capacity in climate change adaptation, disaster risk reduction and sustainable ecosystem protection and management – especially to benefit vulnerable and otherwise-marginalised groups it works with.

Who is involved?

P3DM in Suriname is led by TBI, as part of a joint multi-scale initiative to model ecosystem services and land-use scenarios in the Upper Suriname River basin (see here), in conjunction with WWF Guianas, the University of Utrecht, and the Association of Saramacca Authorities (Vereniging van Saramakaanse Gezagsdragers [VSG]). The initiative is supported by CTA and the UNDP GEF-Small Grant Programme. Through this initiative, TBI aims “to contribute to improved understanding of the impacts of modern-day human interventions on forests, landscapes and people”. One of the project's results was the construction of a number of physical 3D models to visualise and assess human-environment interactions, particularly in the Upper Suriname River basin, which is inhabited by several indigenous Maroon villages and is also the focus of local and external logging and mining extractive activities.

Being on a map means to exist: the Saramaccan experience

Saramaccan communities in Suriname seek government’s recognition of their traditional knowledge

On 23 February 2016, 18 Saramaccan community representatives from the Brownsweg and Upper Suriname River areas met in the capital city, Paramaribo, with key stakeholders and policymakers. The meeting was organised by the Saramaccan Peoples to share the results of a two-year process which led to the visualisation and documentation of their traditional environmental knowledge over a vast area.

Maps generated using data extracted from the 1:15000 scale participatory 3D model of the Brownsweg area (manufactured in November 2015), combined with the digital elevation model obtained from the Foundation for Forest Management and Production Control, Suriname.
It is said that a picture is worth a thousand words and maps may be even more effective in conveying messages when it comes to resource distribution and access. In fact the outcome of the process – which the Saramacca delegates proudly presented at the meeting – consisted of a series of community-generated physical and digital maps.

The maps and various data sets were produced in Saramaccan, English, and Dutch languages as a result of three Participatory 3D modelling (P3DM) exercises that took place in 2014 and 2015, involving 220 residents, including women, youth and the elderly. A film documentary about the process was released in 2015 in Saramaccan, English, and French.


Saramaccan leaders highlighted the uniqueness of the data the communities were able to collate, geo-reference and visualise using highly sophisticated technology, including Geographic Information Systems (GIS). Benefitting from external technical support, knowledge-holders were able to share their mental maps and memories which were used to populate blank 3D models.

The Saramaccan representatives drew attention to the relevance and accuracy of the data, and its accessibility to third parties, provided free prior informed consent for their use was given. "We made the map for it to be used. We want other people to make use of it. We only ask that the data is not used without involving us, the Saramaccan Peoples," concluded a community representative.

The Saramaccan delegates welcomed the use of the data for spatial planning purposes and called on the government and private investors to recognise them as key stakeholders and fully involve them when planning logging activities, protected area management and gold mining concessions within traditional Saramaccan lands.

They urged for the replication of P3DM processes in the rest of the Saramaccan territory so that a complete map of traditional Saramacca lands could be generated. To achieve this, they called on the government, development organisations, private sector, and NGOs present at the meeting to raise the necessary funds.

The event was hosted by Tropenbos International Suriname, WWF Guyanas and the Association of Saamaka Authorities.

In addition to Tropenbos International Suriname, project sponsors included the UNDP-GEF Small Grant Programme and CTA. Contributions by both organisations were duly acknowledged, with participants stating that their valuable contribution established a 'fertile ground' for community empowerment via P3DM which they considered to be a very innovative process. Participants also acknowledged that the P3DM process had inspired other communities who were now requesting support to deploy the P3DM process in their areas.

Speaking of Home - The story of the Mount Elgon Ogiek



The Ogiek peoples live on the slopes of Mount Elgon in Kenya. This documentary shows the Ogiek's relationship to their homeland and to the world.

As indigenous peoples without official minority status in Kenya, the Ogiek have gone through evictions from their native land for decades. Time after another they have returned to their land to continue living in the forest.

The documentary is the Ogiek's story, in their own words, of their hopes before the 2013 Kenyan elections. It was filmed in Chepkitale, Mt. Elgon in 2012 during a 3D mapping workshop.

Through developing a 3D map of their land, the Ogiek not only strengthen their cultural identity, but can show that the land said to belong to someone else, is rightfully theirs.

Credits: The film has been produced by SHALIN Suomi Ry and has been featured at the Helsinki African Film Festival.

Facilitating climate smart adaptation through the use of Participatory 3D Modelling by Neila Bobb-Prescott at the Caribbean-Pacific Agri-Food Forum in Barbados



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 2nd Agribusiness Forum has been supported by the Technical Centre for Agricultural and Rural Cooperation ACP-EU (CTA)

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



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.

We have wings to fly - Join the uav4ag community

The use of unmanned aerial vehicles (UAVs) or drones for management of crops, livestock, fisheries, forests and other natural resource-based activities represents a new technological frontier and opens up a range of exciting opportunities. UAVs offer also opportunities for grassroots’ involvement in monitoring use of and access to the resources their livelihoods depend on.

A community has been established on www.uav4ag.org to cater for practitioners, researchers, farmers, entrepreneurs, service providers operating in developing countries and who are interested in the topic.  Members of the community share their experiences in developing UAV technologies and related software applications and more importantly in making use of small UAVs to improve the assessment and management of crops, fishing grounds and other resource-based activities. Relevant events, capacity building opportunities and other resources are signalled as soon as these are known by members of the community.

Being the use of UAVs for agricultural purposes a recent phenomenon, national aviation authorities and potential users are facing new challenges linked to the use of UAVs within their skies. Hence this Community focuses also on existing and forthcoming policies, laws and regulations governing their use.
