Part 2: Evaluating China’s Tree-Planting Activity
In partnership with Columbia University
Last updated: September 16, 2021
In September 2020, against the backdrop of the coronavirus pandemic and with the global economy still reeling, China pledged that it would achieve carbon neutrality by 2060. In this two-part series, researchers from the Columbia School of International and Public Affairs explore China's progress towards that goal along two vectors: "brown" and "green." Part 2 ("green") examines how tree cover has changed in two provinces as China conducts major tree-planting efforts.

Part 1: Investigating the Growth of Detention Facilities in Xinjiang Using Nighttime Lighting
In partnership with RAND
Last updated: February 26, 2021
A growing body of research has systematically documented Chinese efforts to imprison, detain, and re-educate ethnic Uyghur and minority groups throughout its western Xinjiang province. In this three-part investigation, RAND researchers explore new data on nighttime lighting in Xinjiang to offer new, empirical insights into China’s efforts to reeducate, detain, and imprison its Uyghur and ethnic minority populations across Xinjiang.
Part 2: Have Any of Xinjiang’s Detention Facilities Closed?
In partnership with RAND
Last updated: February 26, 2021
This report, the second in a three-part series, employs a novel empirical approach to systematically assess the current operating status of known detention facilities in Xinjiang using nighttime lighting. This analysis provides new, empirical evidence to suggest that the overwhelming majority of detention facilities in Xinjiang remain active, operational, and in many cases, still under construction – despite Chinese claims to the contrary.
Part 3: Explaining Variation in the Growth and Decline of Detention Facilities across Xinjiang
In partnership with RAND
Last updated: February 26, 2021
This report, the final in our series, explores trends in the growth and decline of nighttime lighting over detention facilities across Xinjiang. It reveals evidence to suggest that long-term prisons have become a greater priority than reeducation centers, along with those located in rural areas or in areas administered by the XPCC, among other trends. Overall, this report helps chart the current trajectory of China’s widespread detention of Uyghur and ethnic minority populations in the region.
