Counter-mapping refers to efforts to map "against dominant power structures, to further seemingly progressive goals".[1] The term was coined by Nancy Peluso[2] in 1995 to describe the commissioning of maps by forest users in Kalimantan, Indonesia, as a means of contesting state maps of forest areas that typically undermined indigenous interests. The resultant counter-hegemonic maps had the ability to strengthen forest users' resource claims.[2] There are numerous expressions closely related to counter-mapping: ethnocartography, alternative cartography, mapping-back, counter-hegemonic mapping, and public participatory mapping.[3] Moreover, the terms: critical cartography, subversive cartography, bioregional mapping, and remapping are sometimes used synonymously with counter-mapping, but in practice encompass much more.[3]

Whilst counter-mapping still primarily refers to indigenous cartographic efforts, it is increasingly being applied to non-indigenous mapping initiatives in economically developed countries.[3] Such counter-mapping efforts have been facilitated by processes of neoliberalism,[4] and technological democratisation.[2] Examples of counter-mapping include attempts to demarcate and protect traditional territories, community mapping, Public Participatory Geographical Information Systems, and mapping by a relatively weak state to counter the resource claims of a stronger state.[5] The power of counter-maps to advocate policy change in a bottom-up manner led commentators to affirm that counter-mapping should be viewed as a tool of governance.[6]

Despite its emancipatory potential, counter-mapping has not gone without criticism. There is a tendency for counter-mapping efforts to overlook the knowledge of women, minorities, and other vulnerable, disenfranchised groups.[7] From this perspective, counter-mapping is only empowering for a small subset of society, whilst others become further marginalised.[8]

Origins

Nancy Peluso, Professor of forest policy, coined the term 'counter-mapping' in 1995, having examined the implementation of two forest mapping strategies in Kalimantan. One set of maps belonged to state forest managers, and the international financial institutions that supported them, such as the World Bank. This strategy recognised mapping as a means of protecting local claims to territory and resources to a government that had previously ignored them.[2] The other set of maps had been created by Indonesian NGOs, who often contract international experts to assist with mapping village territories.[2] The goal of the second set of maps was to co-opt the cartographic conventions of the Indonesian state, to legitimise the claims by the Dayak people, indigenous to Kalimantan, to the rights to forest use.[3] Counter-mappers in Kalimantan have acquired GIS technologies, satellite technology, and computerised resource management tools, consequently making the Indonesian state vulnerable to counter-maps.[2] As such, counter-mapping strategies in Kalimantan have led to successful community action to block, and protest against, oil palm plantations and logging concessions imposed by the central government.[2]

It must, however, be recognised that counter-mapping projects existed long before coinage of the term.[3] Counter-maps are rooted in map art practices that date to the early 20th century; in the mental maps movement of the 1960s; in indigenous and bioregional mapping; and parish mapping.[9]

Parish Maps Project

In 1985, the charity Common Ground launched the Parish Maps Project, a bottom-up initiative encouraging local people to map elements of the environment valued by their parish.[10] Since then, more than 2,500 English parishes have made such maps.[9] Parish mapping projects aim to put every local person in an 'expert' role.[11] Clifford[12] exemplifies this notion, affirming: "making a parish map is about creating a community expression of values, and about beginning to assert ideas for involvement. It is about taking the place in your own hands". The final map product is typically an artistic artefact, usually painted, and often displayed in village halls or schools.[13] By questioning the biases of cartographic conventions and challenging predominant power effects of mapping,[14] The Parish Maps Project is an early example of what Peluso[2] went on to term 'counter-mapping'

Development

Neoliberalism

The development of counter-mapping can be situated within the neoliberal political-economic restructuring of the state.[15] Prior to the 1960s, equipping a map-making enterprise was chiefly the duty of a single agency, funded by the national government.[16] In this sense, maps have conventionally been the products of privileged knowledges.[17] However, processes of neoliberalism, predominantly since the late 1970s, have reconfigured the state's role in the cartographic project.[4] Neoliberalism denotes an emphasis on markets and minimal states, whereby individual choice is perceived to have replaced the mass-production of commodities.[18] The fact that citizens are now performing cartographic functions that were once exclusively state-controlled can be partially explained through a shift from "roll-back neoliberalism", in which the state dismantled some of its functions, to "roll-out neoliberalism", in which new modes of operating have been constructed.[19] In brief, the state can be seen to have "hollowed out" and delegated some of its mapping power to citizens.[20]

Counter-mapping as neoliberal governmentality

Governmentality refers to a particular form of state power that is exercised when citizens self-discipline by acquiescing to state knowledge.[21] Historically, cartography has been a fundamental governmentality strategy,[22] a technology of power, used for surveillance and control.[23] Competing claimants and boundaries made no appearance on state-led maps.[23] This links to Foucault's[24] notion of "subjugated knowledges" - ones that did not rise to the top, or were disqualified.[22] However, through neoliberalising processes, the state has retracted from performing some of its cartographic functions.[15] Consequently, rather than being passive recipients of top-down map distribution, people now have the opportunity to claim sovereignty over the mapping process.[25] In this new regime of neoliberal cartographic governmentality the "insurrection of subjugated knowledges" occurs,[24] as counter-mapping initiatives incorporate previously marginalised voices.

Technological democratisation?

In response to technological change, predominantly since the 1980s, cartography has increasingly been democratised.[26] The wide availability of high-quality location information has enabled mass-market cartography based on Global Positioning System receivers, home computers, and the Internet.[27] The fact that civilians are using technologies which were once elitist led Brosius et al.[28] to assert that counter-mapping involves "stealing the master's tools". Nevertheless, numerous early counter-mapping projects successfully utilised manual techniques, and many still use them. For instance, in recent years, the use of simple sketch mapping approaches has been revitalised, whereby maps are made on the ground, using natural materials.[29] Similarly, the use of scale model constructions and felt boards, as means of representing cartographic claims of different groups, have become increasingly popular.[7] Consequently, Wood et al.[9] assert that counter-mappers can "make gateau out of technological crumbs".

Public Participation Geographical Information Systems

In recent years, Public Participation Geographical Information Systems (PPGIS) have attempted to take the power of the map out of the hands of the cartographic elite, putting it into the hands of the people. For instance, Kyem[30] designed a PPGIS method termed Exploratory Strategy for Collaboration, Management, Allocation, and Planning (ESCMAP). The method sought to integrate the concerns and experiences of three rural communities in the Ashanti Region of Ghana into official forest management practices.[30] Kyem[30] concluded that, notwithstanding the potential of PPGIS, it is possible that the majority of the rich and powerful people in the area would object to some of the participatory uses of GIS. For example, loggers in Ghana affirmed that the PPGIS procedures were too open and democratic.[30] Thus, despite its democratising potential, there are barriers to its implementation. More recently, Wood et al.[9] disputed the notion of PPGIS entirely, affirming that it is "scarcely GIS, intensely hegemonic, hardly public, and anything but participatory".

Counter-mapping as governance

Governance makes problematic state-centric notions of regulation, recognising that there has been a shift to power operating across several spatial scales.[31] Similarly, counter-mapping problematises state distribution of cartography, advocating bottom-up participatory mapping projects (see GIS and environmental governance). Counter-mapping initiatives, often without state assistance, attempt to exert power. As such, counter-mapping conforms to Jessop's[20] notion of "governance without government". Another characteristic of governance is its "purposeful effort to steer, control or manage sectors or facets of society" towards a common goal.[32] Likewise, as maps exude power and authority,[33] they are a trusted medium[34] with the ability to 'steer' society in a particular direction. In brief, cartography, once the tool of kings and governments,[35] is now being used as a tool of governance - to advocate policy change from the grassroots.[6] The environmental sphere is one context in which counter-mapping has been utilised as a governance tool.[6]

Counter-mapping as environmental governance

In contrast to expert knowledges, lay knowledges are increasingly valuable to decision-makers, in part due to the scientific uncertainty surrounding environmental issues.[36] Participatory counter-mapping projects are an effective means of incorporating lay knowledges[37] into issues surrounding environmental governance. For instance, counter-maps depicting traditional use of areas now protected for biodiversity have been used to allow resource use, or to promote public debate about the issue, rather than forcing relocation.[6] For example, the World Wide Fund for Nature used the results of counter-mapping to advocate for the reclassification of several strictly protected areas into Indonesian national parks, including Kayan Mentarang and Gunung Lorentz.[6] The success of such counter-mapping efforts led Alcorn[6] to affirm that governance (grassroots mapping projects), rather than government (top-down map distribution), offers the best hope for good natural resource management. In short, it can be seen that "maps are powerful political tools in ecological and governance discussions".[6]

Types of counter-mapping

Numerous counter-mapping types exist, for instance: protest maps, map art, counter-mapping for conservation, and PPGIS. In order to emphasise the wide scope of what has come to be known as counter-mapping, three contrasting counter-mapping examples are elucidated in this section: indigenous counter-mapping, community mapping, and state counter-mapping, respectively.

Indigenous counter-mapping

Counter-mapping has been undertaken most in the Third World.[13] Indigenous peoples are increasingly turning to participatory mapping, appropriating both the state's techniques and manner of representation.[38] Counter-mapping is a tool for indigenous identity-building,[39] and for bolstering the legitimacy of customary resource claims.[2] The success of counter-mapping in realising indigenous claims can be seen through Nietschmann's[40] assertion:

More indigenous territory has been claimed by maps than by guns. And more Indigenous territory can be reclaimed and defended by maps than by guns.

Creation of Nunavut

The power of indigenous counter-mapping can be exemplified through the creation of Nunavut. In 1967, Frank Arthur Calder and the Nisaga'a Nation Tribal Council brought an action against the Province of British Columbia for a declaration that aboriginal title to specified land had not been lawfully extinguished. In 1973, the Canadian Supreme Court found that there was, in fact, an aboriginal title. The Canadian government attempted to extinguish such titles by negotiating treaties with the people who had not signed them.[9] As a first step, the Inuit Tapirisat of Canada studied Inuit land occupancy in the Arctic, resulting in the publication of the Inuit Land Use and Occupancy Project.[41] Diverse interests, such as those of hunters, trappers, fishermen and berry-pickers mapped out the land they had used during their lives.[9] As Usher[42] noted:

We were no longer mapping the 'territories' of Aboriginal people based on the cumulative observations of others of where they were…but instead, mapping the Aboriginal peoples’ own recollections of their own activities.

These maps played a fundamental role in the negotiations that enabled the Inuit to assert an aboriginal title to the 2 million km² in Canada, today known as Nunavut.[9] Evidently, counter-mapping is a tool by which indigenous groups can re-present the world in ways which destabilise dominant representations.[43]

Community mapping

Community mapping can be defined as: "local mapping, produced collaboratively, by local people and often incorporating alternative local knowledge".[13] OpenStreetMap is an example of a community mapping initiative, with the potential to counter the hegemony of state-dominated map distribution.[44]

OpenStreetMap

OpenStreetMap home page.

OpenStreetMap (OSM), a citizen-led spatial data collection website, was founded by Steve Coast in 2004. Data are collected from diverse public domain sources; of which GPS tracks are the most important, collected by volunteers with GPS receivers.[13] As of 10 January 2011 there were 340,522 registered OSM users, who had uploaded 2.121 billion GPS points onto the website.[45] The process of map creation explicitly relies upon sharing and participation; consequently, every registered OSM user can edit any part of the map. Moreover, 'map parties' - social events which aim to fill gaps in coverage, help foster a community ethos.[46] In short, the grassroots OSM project can be seen to represent a paradigm shift in who creates and shares geographic information - from the state, to society.[47] However, rather than countering the state-dominated cartographic project, some commentators have affirmed that OSM merely replicates the 'old' socio-economic order.[48] For instance, Haklay[48] affirmed that OSM users in the United Kingdom tend not to map council estates; consequently, middle-class areas are disproportionately mapped. Thus, in opposition to notions that OSM is a radical cartographic counter-culture,[49] are contentions that OSM "simply recreates a mirror copy of existing topographic mapping".[50]

State counter-mapping

What has come to be known as counter-mapping is not limited to the activities of non-state actors within a particular nation-state; relatively weak states also engage in counter-mapping in an attempt to challenge other states.[51]

Competing cartographic representations: East Timor versus Australia

East Timor's on-going effort to gain control of gas and oil resources from Australia, which it perceives at its own, is a form of counter-mapping. This dispute involves a cartographic contestation of Australia's mapping of the seabed resources between the two countries.[51] As Nevins[51] contends: whilst Australia's map is based on the status quo - a legacy of a 1989 agreement between Australia and the Indonesian occupier of East Timor at that time, East Timor's map represents an enlarged notion of what its sea boundaries should be, thereby entailing a redrawing of the map. This form of counter-mapping thus represents a claim by a relatively weak state, East Timor, to territory and resources that are controlled by a stronger state, Australia.[3] However, Nevins[51] notes that there is limited potential of realising a claim through East Timor's counter-map: counter-mapping is an effective strategy only when combined with broader legal and political strategies.[51]

Criticisms

Counter-mapping's claim to incorporate counter-knowledges, and thereby empower traditionally disempowered people, has not gone uncontested.[52] A sample of criticisms leveled at counter-mapping:

  • Counter-mapping fails to recognise that community is a constantly shifting, fluid process, too often relying on a notion of community as bounded and fixed. As such, the process of mapping communicates and naturalises who does, and who does not, belong within particular boundaries.[53]
  • Due to the power imbalance between indigenous claims and those of the state, the language and tools of the dominant society must be used by those under its control. The process of using another's tools can change the ideas represented, resulting in a map of unpredictable quality.[3]
  • Counter-mapping is in danger of becoming the 'thing to do'; a "magic bullet applied uncritically".[54]
  • There is a geography to the success of counter-mapping. In Tibet, counter-mapping is of limited political utility as mapmaking is not enfranchised and cannot be scaled up, for instance, to settle legal battles over land tenure and resource rights through the regulatory offices of the state.[5]
  • Counter-mapping projects utilising GIS require significant knowledge and computer literacy above that of lay individuals.[55]
  • Investment in specialised computers and software often results in prohibitive mapping costs for a large majority of local people, particularly in poor areas. As some groups prove more capable of adopting the technologies than others, counter-mapping projects can deepen divisions within communities along gender and economic lines.[56]

To summarise, whilst counter-mapping has the potential to transform map-making from "a science of princes",[57] the investment required to create a map with the ability to challenge state-produced cartography means that counter-mapping is unlikely to become a "science of the masses".[2]
