Urban ecosystems play a crucial role in providing wide range of services to their inhabitants, and functioning is deeply intertwined with the effects climate change. The present review explores dynamic interplay between urban ecosystem change, highlighting reciprocal relationships, impacts, adaptation strategies associated these phenomena. environment, its built infrastructure, green spaces, diverse human activities, offers various that enhance wellbeing resilience dwellers. offer regulatory like temperature control, air quality upkeep, stormwater management, plus provisioning food water. They also provide cultural benefits, promoting recreation community unity. However, change poses significant challenges services. Rising temperatures, altered precipitation patterns, increased frequency extreme weather events can disrupt ecosystems, impacting provision Heatwaves heat island compromise health energy demands, while changes rainfall patterns strain management systems lead flooding. Moreover, biodiversity ecological processes, affecting overall sustainability ecosystems. To address challenges, cities are adopting recognize interdependence Green infrastructure interventions, such as creation parks, roofs, gardens, aim mitigate impacts by enhancing regulation temperature, improving quality, reducing runoff. Additionally, planning design approaches prioritize compact walkable neighborhoods, public transportation reliance on fossil fuels. Furthermore, engaging communities measures for ensuring equitable distribution building social resilience. Therefore, article highlights comprehensive understanding interrelationship implications.

Assessment the impact of urban expansion on cropland net primary productivity in Northeast China

Ecological Indicators, Journal Year: 2024, Volume and Issue: 159, P. 111698 - 111698

Published: Feb. 1, 2024

Urban development inevitably comes with the loss of prime agricultural land, leading to a decline in cropland productivity. The Northeast region is an important grain-producing China, and land great significance ensuring national food security. Here, use cover data MODIS-NPP were used comprehensively understand direct adverse influence urban growth on net primary productivity (NPP) China. results indicated that (1) area increased by total 5230.00 km2 since 2000. phenomenon was particularly notable cities near central transportation trunk line along southern coastal regions. (2) more than half newly added patches originated from cropland. Between 2000 2020, expansion China resulted 0. 85 Tg C NPP. (3) there significant regional variation NPP loss. low altitude slope regions experienced most Meanwhile, large developed caused losses, dispersed had broader impact concentrated expansion. (4) when converting crop yield, it revealed reduction 0.91 million tons grain yield These findings provide valuable insights for protection strategies offering crucial guidance sustainable practices.

Spatiotemporal evolution and relationship between construction land expansion and territorial space conflicts at the county level in Jiangsu Province

Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110662 - 110662

Published: July 18, 2023

In rapidly urbanizing areas, intense human development activities and fierce competition for spatial resources have led to apparent territorial space conflicts. This paper selects Jiangsu Province as the study area explore spatiotemporal evolution characteristics response relationship between expansion of county-level construction land conflicts from 1985 2020 provide a reference regional optimization. The results show that intensity (CEI) at county level showed characteristic greater power in southeast than northwest. mode (SEI) was mainly characterized by spread type, with experiencing marginal expansion, emergence new independent points, then process agglomeration distribution. From 2020, there significant increase an aggregation level. regions high index (SCII) values changes (SCIIC) were located Xuzhou, Nanjing, junction Changzhou, Wuxi, Suzhou, Zhenjiang. There positive correlation CEI SCIIC, units increased south north. SEI strong Nantong, Wuxi. population density GDP also affect SCIIC. strengthens understanding related relationships over long time, which can decision-making basis regulation optimization Province.

Overcoming Barriers to Managing Urban Green Spaces in Metropolitan Areas: Prospects from a Case Study in an Emerging Economy

Sustainability, Journal Year: 2024, Volume and Issue: 16(16), P. 7019 - 7019

Published: Aug. 15, 2024

Urban green spaces (UGS) are vital for the quality of life in cities. However, managing these metropolitan areas is increasingly challenging. There a critical gap regarding specific challenges and strategies employed by municipalities varying sizes emerging economies. Most existing research focuses on developed countries, leaving void understanding how economies manage UGS under different constraints. This study delves into associated with region São Paulo (MRSP), Brazil, comparing experiences to provide empirical evidence that can inform policy making urban planning practices similar contexts. A structured questionnaire was distributed environmental departments across 39 MRSP. The survey included questions population size, priority given UGS, faced adopted overcome barriers. Chi-square tests were used analyze association between municipality size identified strategies. found larger face significant barriers related high density land use conflicts, which less pronounced smaller municipalities. all Policy makers should focus promoting vertical spaces, expanding greening programs, ensuring equitable resource allocation. Public–private partnerships community involvement processes crucial sustainable management. Integrating policies broader development plans essential creating cohesive environments. Further conduct comparative studies multiple regions countries more comprehensive management globally. integrates insights from ecology, landscape architecture, public policy, emphasizing interdisciplinary approach required effective findings offer practical guidance planners architects design landscapes.

The rapid increase in urban population density driven by development has intensified inequity green space distribution. Identifying the causes of changes equity and developing strategies to improve greening are crucial for optimizing resource allocation alleviating social inequalities. However, long-term spatio-temporal evolution visibility remains underexplored. This study utilized “Time Machine” feature capture street view images from 2014, 2017, 2021, analyzing its across residential communities Wuhan. Deep learning techniques statistical methods, including Gini coefficient location quotient (LQ), were employed assess distribution spatial street-level greenery. results showed that overall Wuhan increased 4.18% between 2014 2021. this improvement did not translate into better equity, as consistently ranged 0.4 0.5.

Urban–rural integration (URI) is essential to achieving sustainable development. However, the rural areas surrounding large cities typically have a scale and significant differences in development conditions. It necessary formulate policies by category better promote integrated between urban areas, stimulate vitality, create more opportunities for This study constructs an evaluation system under URI, using Xi’an metropolitan area as case study. A clustering algorithm enhanced random forest (RF)–principal component analysis (PCA)–partitioning around medoids (PAM) method applied evaluate comprehensively. Key findings this include following: (i) URI should be decoupled from administrative divisions, considering complex impacts of multi-town functional spillover; (ii) ecological environment, economic development, public service allocation, construction land supply are key factors influencing URI; (iii) overall index presents “high center, low east west” pattern. The with high Xianyang, while other show insufficient communication neighboring villages; (iv) can categorized into four types integration: ecological, ecological–economic, ecological–social–spatial, ecological–economic–social–spatial, which exhibit outward expansion layers extension along east–west axis spatial structure integration.
