Is a pixel worth 1000 words? Critical remote sensing and China's Belt and Road Initiative

Abstract

As a novel means of researching China's Belt and Road Initiative (BRI), this article advances a critical remote sensing agenda that connects the view from above provided by satellite imagery with the grounded, qualitative methodologies more typical of political geography such as ethnographic fieldwork. Satellite imagery is widely used to produce empirics relating to the BRI, and the Chinese state is showing increasing interest in applying Earth observation data to governance. A more critical approach attentive to the politics of remote sensing, especially in light of China's emergence as a space and satellite power and its embrace of big data, is needed to more precisely reveal what changing pixels represent on the ground and expose the potential issues with data captured from high above the planet. This paper offers three theoretical and methodological objectives for critical remote sensing. First, I reflect on the geopolitics involved in the production and analysis of satellite imagery. Second, through analysis of night light imagery, which captures illuminated anthropogenic activities, I interrogate metanarratives of development. Third, I engage with qualitative methods by “ground-truthing” remote sensing with ethnographic observations along China's borders. I also seek to avoid the methodological nationalism often present in remote sensing research by situating these mixed-methods case studies at scales above and below the nation-state. As one of the largest development interventions in history materializes, pursuing critical remote sensing can create opportunities for social scientists to leverage quantitative and geospatial methods in support of more equitable and sustainable futures.
