Between monitoring and surveillance: Geographies of emerging drone technologies in contemporary conservation

Progress in Environmental Geography, Journal Year: 2024, Volume and Issue: 3(1), P. 17 - 39

Conservation has employed technologies for monitoring and visual capture since its inception in the nineteenth century. Since then, capacities of conservation have developed considerably, affording a wide range data relating to ecological change biodiversity loss. However, new introduce fresh ethical political issues into environmental protection, especially as they can be used – deliberately or accidentally collect information about human activities. This potential is important, given that many areas protection are also longstanding conflict. We focus here on implications surrounding drones, which photographic video footage include images humans. review approaches technology, visuality, surveillance across beyond geography over last two decades, teasing out conceptual support nuanced critical analysis drones. Our focuses ways drones alter (i) processes decision-making, (ii) dynamics fearmongering control, (iii) securitisation protected areas, (iv) production circulation (racial) stereotypes, (v) practices outcomes justice. unpack these themes through three case studies from our own fieldwork, clarifying intentional non-intentional emerge, will vital explore further future.

Drones as a Threat to Wildlife: YouTube Complements Science in Providing Evidence about Their Effect

Environmental Conservation, Journal Year: 2019, Volume and Issue: 46(3), P. 205 - 210

Published: June 14, 2019

Summary Although drones are becoming very common in the skies, most concerns about their use not focused on possible impact wildlife. We used information available from scientific literature effects of wildlife and complement it with Internet (YouTube) to evaluate whether recreational activities using produce behavioural responses Scientific papers specifically evaluating scarce but increasing. Nonetheless, we found abundant videos which many species different taxonomic groups multiple countries presented drone overflights. Furthermore, 26% that were disturbed included one International Union for Conservation Nature categories threat. aerial terrestrial habitats more likely show a response than those occupying aquatic habitats. The is source evidence disturbances should be considered, particularly activities. advocate technology, argue funding effort devoted impacts call educational programmes laypeople who recreation research regulations sensitive areas.

Response efforts in emergency applications such as border protection, humanitarian relief and disaster monitoring have improved with the use of Unmanned Aerial Vehicles (UAVs), which provide a flexibly deployed eye sky. These been further advances autonomous behaviours obstacle avoidance, take-off, landing, hovering waypoint flight modes. However, most UAVs lack decision making for navigating complex environments. This limitation creates reliance on ground control stations to and, therefore, their communication systems. The challenge is even more indoor operations, where strength Global Navigation Satellite System (GNSS) signals absent or weak compromises aircraft behaviour. paper proposes UAV framework navigation address uncertainty partial observability from imperfect sensor readings cluttered scenarios. design allocates computing processes onboard controller companion computer UAV, allowing it explore dangerous areas without supervision physical presence human operator. system illustrated under Search Rescue (SAR) scenario detect locate victims inside simulated office building. problem modelled Partially Observable Markov Decision Process (POMDP) solved real time through Augmented Belief Trees (ABT) algorithm.
