Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110682 - 110682

Published: July 18, 2023

Urban zones across the world have experienced a massive expansion in recent decades, affecting food production, carbon storage, and biodiversity, further threatening realization of UN's Sustainable Development Goals (SDGs), particularly SDG 2 (zero hunger), 13 (climate action), 15 (life on land). These enormous impacts are even more worrying coastal areas where urbanization has been continuously accelerated. However, we poor understanding about magnitude reduction natural habitat crucial ecosystem services over time caused by urban areas. Here chose zone eastern China using high-resolution dataset land-use/land-cover (LULC) to investigate influences growth from 1990 2018. The results showed that: (1) China's region resulted an estimated 2061.14 km2 habitat, 154.13 Tg C 1.67 cropland net primary 148.02 × 103 quality; (2) production loss 1.34 106 tons crop which is comparable meeting basic demands 3.35 million hungry people for year; (3) overall degradation reached 1838.28 km2, with grade 1 area accounting largest portion (801.18 km2), representing 43.58% total degradation; (4) contributor storage (63.83%) was large-scale conversion areas, while quality were primarily due occupation forests (42.62%).

Assessment of water-related ecosystem services based on multi-scenario land use changes: focusing on the Poyang Lake Basin of southern China

Ecological Indicators, Journal Year: 2024, Volume and Issue: 158, P. 111549 - 111549

Published: Jan. 1, 2024

A scientific understanding of the trends water-related ecosystem services (WESs) under different scenarios is crucial to improving WESs and maintaining ecological security. However, there a lack high-resolution land use simulation assessment SSP-RCP scenarios, impacts land-use change (LUC) on are not clear. This study focused Poyang Lake Basin (PYLB), utilizing PLUS model InVEST explore dynamic changes historically in future, reveal specific LUC from 2000 2020. The results demonstrated that: (1) forest increased both SSP1-2.6 SSP2-4.5 but first then decreased SSP5-8.5 scenarios; Cropland significantly construction showed an expansion trend three scenarios. (2) From 2020, only water purification capacity decreased, while rest increased. Under scenario, overall benefits PYLB were highest. (3) Between deforestation brought about greatest increase yield (+9.06 × 108 m3). most conservation loss (−18.19 Additionally, cropland reduction largest soil retention (+3.94 105 t +4.79 t) enhanced purification, opposite was true for deforestation. conclusions can provide important basis protection high-quality development PYLB.

Scale effects on the supply–demand mismatches of ecosystem services in Hubei Province, China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 153, P. 110461 - 110461

Published: June 10, 2023

Understanding the patterns, relationships, and driving forces between ecosystem services (ESs) supply–demand at multiple spatial scales can facilitate sustainable hierarchical management. However, scale effects of ESs mismatches were typically ignored, resulting in inadequate targeted promotion policies. This study identified key (grain production, water yield, carbon sequestration, soil conservation) using ecological ratio bivariate Moran's I three grid county from 2000 to 2020 Hubei Province, China. Then regression models applied explore these mismatches. The major results revealed that (1) Province counties located away urban areas self-sufficient supply–demand, but numbers declined over twenty years. characteristics some patches may be obscured coarser scales. (2) directions socioecological drivers robust, their intensities changed significantly four normalized difference vegetation index was primary positive driver fine scale, while population, economy, proportion construction land became dominant Factors influencing more diverse compared coarse scale. (3) Efficient strategies scale-dependent place-based. Different management units should clarify responsibilities strengthen linkages upper lower levels achieve development. At provincial level, strengthening interregional cooperation allocating surplus grain resources southwest regions contributes balancing regional ESs. adopting region-specific based on delineating zones is crucial. finer levels, incorporating micro-scale mismatch locations natural background information provide valuable guidance for localized protection restoration projects. findings underscore strengths conducting assessments scales, enabling different government enhance effective prevent misinformation.

Characteristics of urban expansion in megacities and its impact on water-related ecosystem services: A comparative study of Chengdu and Wuhan, China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 158, P. 111322 - 111322

Published: Nov. 28, 2023

The megacity expansion that continues to occur in developing countries is an unavoidable trend at this stage, yet there exists a dearth of knowledge regarding the comprehensive impacts urban on water-related ecosystem services (WESs) within these areas. Taking Chengdu and Wuhan, two megacities upper middle Yangtze River Economic Belt China as study area, first compare magnitude, rate, spatial divergence, mode expansion; then evaluate its impact three typical types WESs, i.e., water yield (WY), purification (WP), habitat quality (HQ) using econometric models bivariate Moran's I. research findings show Chengdu's suburbs tend experience edge-based along rivers, while Wuhan's city center also spreads outward from river junctions Han rivers. Urban negatively all effect greater than Wuhan. WY Wuhan severely impacted by expansion, WP well. HQ suffers largest negative impact. reveals spillover with extensive externalities WESs centers both cities positive southwestern Chengdu. Based results, we suggest should focus protecting limiting cross-regional suburbs. Attention be paid water-ecological protection suburb City managers consider ecological zoning geared toward conservation address adverse expansion.
