An exploration of market mechanisms to the wicked problem of space debris 太空垃圾棘手问题的市场机制探究 Una exploración de los mecanismos del mercado para resolver el complejo problema de los desechos espaciales

open access: yesRisk, Hazards &Crisis in Public Policy, EarlyView.
Abstract Near‐earth orbits are becoming congested because of a rapid growth in the number of satellites and space debris, which presents a real threat to the sustainable use of space and the safety of the Earth. Despite space scientists and public policymakers having been actively seeking solutions for decades, solving the problem has been put off ...

Examining wildfire dynamics using ECOSTRESS data with machine learning approaches: the case of South‐Eastern Australia's black summer

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Australia experienced one of the most devastating and intense wildfire seasons on record in 2019–2020. One challenge is to create effective models to identify areas prone to wildfires and understand the vulnerable conditions that will lead to these catastrophic events.

Advancing the mapping of vegetation structure in savannas using Sentinel‐1 imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
As vegetation structure monitoring is important for the understanding and conservation of savanna ecosystems, we explored the utility of C‐band synthetic aperture radar imagery for mapping both grassland and woody vegetation structure in the Greater Serengeti‐Mara Ecosystem.

Spatiotemporal patterns and driving factors for vegetation growth status in the upper reaches of the Yellow River

open access: yesRiver, EarlyView.
This study developed the WEP‐CHC model, integrating vegetation growth dynamics into the hydrological WEP framework, to explore the spatiotemporal patterns and driving mechanisms of vegetation growth status (VGS) in the upper Yellow River. The results revealed significant spatiotemporal variability in VGS, with annual hydrothermal conditions and soil ...

Space Economy and Sustainability: A Systematic Review

open access: yesSustainable Development, EarlyView.
ABSTRACT The space economy is booming thanks to the increasing investment of government agencies, private companies, and venture capitalists. From the beginning of the New Space era, the array of actors involved in the development of technologies for extra‐terrestrial activities has increased, as well as the downstream applications that foster ...
