As climate change makes the future of urban living appear increasingly daunting, many people and communities are already experiencing climate impacts. This paper highlights the disproportionate nature of climate change, from unequal historical responsibilities to unequal climate impacts that fall on the most vulnerable and unequal prospects that hinder people and countries from adapting to a changing climate now and in the future. Through an arts-based literature review, the paper demonstrates that climate change's effects and responses often reinforce existing inequalities, systematically pushing people, communities and entire countries into further vulnerability. Acknowledging that spatial processes play a critical role in creating, shaping and perpetuating inequalities and oppression, we advocate for spatial justice in climate action and offer eight principles to support spatial scholars and practitioners in adopting a critical perspective on climate change in urban contexts. ...

Drones developed for interplanetary space missions require full autonomy of operations including safe landing and hovering due to the delay in communication. For operation in low atmospheric densities, coaxial helicopters are best suited and they are capable of handling manoeuvres due to their small footprints and ease of operation. However, the dynamics of the helicopter is coupled in lateral axes which need to be compensated for precise control. The present solutions include vision-based tracking in order to decouple the dynamics, which needs additional hardware. In this paper, a decoupling controller is presented that employs an accelerometer-based force feedback system for measuring the undesired forces in off-axis which does not need any additional hardware. The simulation results indicate that the force feedback methodology is very effective in controlling the off-axis drift of the coaxial helicopter. ... Read more
