SignificanceUnderstanding the impacts of urbanization and associated urban land expansion on species is vital for informed planning that minimizes biodiversity loss. Predicting habitat will be lost to over 30,000 under three different future scenarios, we find up 855 are directly threatened due unmitigated urbanization. Our projections pinpoint rapidly urbanizing regions sub-Saharan Africa, South America, Mesoamerica, Southeast Asia where, without careful planning, expected cause particularly large findings highlight urgent need an increased focus in global conservation strategies identify high-priority areas this engagement.

Global impacts of future urban expansion on terrestrial vertebrate diversity

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: March 25, 2022

Abstract Rapid urban expansion has profound impacts on global biodiversity through habitat conversion, degradation, fragmentation, and species extinction. However, how future will affect needs to be better understood. We contribute filling this knowledge gap by combining spatially explicit projections of under shared socioeconomic pathways (SSPs) with datasets terrestrial (amphibians, mammals, birds). Overall, lead 11–33 million hectares natural loss 2100 the SSP scenarios disproportionately cause large fragmentation. The within current key priority areas is projected higher (e.g., 37–44% in WWF’s Global 200) than average. Moreover, land conversion reduce local within-site richness 34% abundance 52% per 1 km grid cell, 7–9 may lost 10 cell. Our study suggests an urgent need develop a sustainable development pathway balance conservation.

Habitat fragmentation, biodiversity loss and the risk of novel infectious disease emergence

Journal of The Royal Society Interface, Journal Year: 2018, Volume and Issue: 15(149), P. 20180403 - 20180403

The number of microbes on Earth may be 10 30 , exceeding all other diversity. A small these can infect people and cause disease. diversity parasitic organisms likely correlates with the hosts they live in mammal for zoonotic infections increases species richness among mammalian orders. Thus, while habitat loss fragmentation reduce diversity, encroachment by into species-rich areas increase exposure to novel infectious agents from wildlife. Here, we present a theoretical framework that exploits species–area relationship link biodiversity. We model changes human through defined classes predict increased division intrinsically hazard modelled biological systems. apply our African tropical forests as an example. Our results suggest it is possible identify high-risk mitigation surveillance disease emergence measures this risk conserving

Urbanisation drivers and underlying mechanisms of terrestrial insect diversity loss in cities

Ecological Entomology, Journal Year: 2021, Volume and Issue: 46(4), P. 757 - 771

Published: April 30, 2021

1. Urbanisation is one of the main land‐use changes behind global insect collapse. Despite that previous studies have described negative effects urbanisation on communities, so far there no synthesis considers multiple urban drivers, their combined effects, and role species traits altogether. 2. Here we developed an integrative framework underlying mechanisms terrestrial loss in cities by exploring five leading drivers: impervious surfaces, habitat fragmentation, heat island, pollution, exotic plants. For each driver, identified direct indirect (mediated through interactions or resources) populations emphasising as moderators such effects. 3. Body size, mobility, oviposition/nesting requirements were frequently defined vulnerability to drivers. Urban island pollution deserve further research from a community‐level approach. Direct drivers dominated literature, while most paths mediated resources rather than interactions. 4. In conclusion, our review showed challenges recognising particular for driver By doing so, intended encourage researchers address some gaps noticed order fully understand how affecting communities. Finally, outlined recent planning strategies future successfully conserve biodiversity.

Improved human greenspace exposure equality during 21st century urbanization

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Oct. 13, 2023

Greenspace plays a crucial role in urban ecosystems and has been recognized as key factor promoting sustainable healthy city development. Recent studies have revealed growing concern about greenspace exposure inequality; however, the extent to which urbanization affects human associated inequalities over time remains unclear. Here, we incorporate Landsat-based 30-meter time-series mapping population-weighted framework quantify changes equality (rather than equity) for 1028 global cities from 2000 2018. Results show substantial increase physical coverage an improvement greenspace, leading reduction inequality past two decades. Nevertheless, observe contrast rate of between Global South North, with faster South, nearly four times that North. These findings provide valuable insights into impact on nature environmental change can help inform future greening efforts.

Detecting global urban expansion over the last three decades using a fully convolutional network

Environmental Research Letters, Journal Year: 2018, Volume and Issue: 14(3), P. 034008 - 034008

Published: Dec. 18, 2018

The effective detection of global urban expansion is the basis understanding sustainability. We propose a fully convolutional network (FCN) and employ it to detect from 1992–2016. found that land area increased 274.7 thousand km2–621.1 km2, which an increase 346.4 km2 growth by 1.3 times. results display relatively high accuracy with average kappa index 0.5, 0.3 higher than those existing datasets. Three major advantages proposed FCN contribute improved accuracy, including integration multi-source remotely sensed data, combination features at multiple scales, ability address lack training samples for historical land. Thus, has great potential effectively expansion.
