The technology enables researchers to peer through dense forest canopies, rapidly providing high-resolution scans of the landscape below.
This growing observational power is central to the scientific value of remote sensing technologies but also brings into focus the conditions, interests and power structures under which they are used. Now, in a new paper in Nature Ecology & Evolution, an international team of researchers argues that the visibility brought by high-resolution remote sensing may result in the loss of what have long been cultural refuges against dominant powers and that ethical considerations should be integral to research planning when using such data. "Remote sensing research has often been framed as a technical exercise to support more efficient management and observation," says Patrick Roberts, director of the Department of Coevolution of Land Use and Urbanization at the Max Planck Institute of Geoanthropology (MPI GEA) and corresponding author of the study.
"Yet, mapping is never only a technical practice, and decisions about what is revealed and how and where are inherently ethical and political." The new paper acknowledges the value of remote sensing but argues that while discipline-specific ethical discussions around the technology have occurred, they have tended to focus on technicalities of research and data presentation rather than whether and under what conditions to map. The authors organize these considerations into three broad areas: "These issues challenge us to think about the oft-promoted but simplistic idea of mapping 'for the greater good,'" says Gabriel Hes of the University of Toulouse, lead author of the current paper. "Whose 'greater good' are we talking about, and are forest mapping technologies reinforcing imbalances in knowledge production, political power and environmental impacts?
In this paper, we urge our colleagues to reflect on the ethical costs of their methods, considering the potential intersectional impacts (on race, age, gender, wealth, class) of high-resolution mapping of tropical forests." "We are not arguing that remote sensing is inherently 'bad'," Roberts adds. "Indeed, it has been used by local communities to safeguard their territories and rights. Rather, we urge scientists to consider the varied ethical dimensions affecting their research, whether they carry out mapping on local, regional or global scales." The authors conclude with a framework for helping researchers decide when mapping is inappropriate.
In reframing environmental science as an asset for transformative change, they hope these considerations will ensure that tropical forest mapping best serves the needs of those most affected by the current global ecological crisis.
