“…The interactions between regional development processes and ecosystems have become the focus of the human-land relationship worldwide. Previous studies on regional development and ecosystem services have focused on the following three aspects: the impact of land use change and landscape pattern evolution on ESV and the response of ESV to land use degree [3,[13][14][15][16][17][18][19][20][21]; anthropogenic changes to the quantity, patterns, functions, and structures of land use through urbanization that affect ecosystem services or the relationship between urbanization and ecosystems [22][23][24][25][26][27][28][29][30][31]; and the formulation and implementation of spatial land planning, which raises awareness regarding the multiobjective development of urban space for society, economy, and ecology [32][33][34][35][36][37]. It is critical to consider ESV and spatial responses to regional sustainable development and optimize land resource management policies to improve ecosystem services.…”

This study analyzed data from 1995, 2005, and 2015 using mathematical calculations, spatial analysis, and a geographically weighted regression model. The results showed that from 1995 to 2015, the comprehensive regional development degree (RDD) of urban agglomeration in the middle of Jilin Province increased overall, with the average RDD increasing from 0.250 in 1995 to 0.323 in 2015. Especially in Changchun, a sub-provincial city, the RDD increased by nearly one-third, and the gap between this and other cities has been increasing. However, the ecosystem service value (ESV) decreased overall, with the average ESV decreasing from 108.3 in 1995 to 105.4 in 2015, and showed a strong spatial correlation. The maximum quantile in southeast–northwest direction was 1.712, with good homogeneity. The spatial influence coefficient of the RDD on the ESV showed a trend from positive to negative in the northwest–southeast direction. This value decreased continuously while the negative agglomeration area was gradually expanding, corresponding to the stressful effects of the RDD on ESV. The results of this study can provide a reference for urban planning and development as well as encourage reasonable regional spatial planning to ensure the sustainable development of urban agglomerations.

“…Sannigrahi et al [9] discovered that decreases in forestland, wetland, and water areas, along with the expansion of built-up land, has resulted in a considerable decline in global ESs by measuring the global ESV and its response to land-use change from 1995 to 2015. Rahman et al [19] examined the effect of land-use and land-cover changes on the value of urban ESs in Dhaka, Bangladesh. They discovered that the growth of built-up land came at the expense of farmland, forestland, and water areas, and the regional ESV continued to decline.…”

The Grain for Green Project (GGP) has influenced Shaanxi Province’s land-use pattern, resulting in a shift in ecosystem service value (ESV). Exploring the spatial and temporal evolution of the pattern of land use and ESV in Shaanxi Province, before and after the project’s implementation, can give a theoretical foundation for regional land-use planning. For this study, we used the transfer matrix and the value equivalent approaches to investigate the influence of project implementation on the spatial distribution and evolution of patterns of land use and ESV in Shaanxi Province based on four periods of land-use data from 1990 to 2020. The results suggest the following: (1) Farmland, forestland, and grassland were the most common land-types in Shaanxi Province. Farmland, forestland, and grassland in Shaanxi Province were all altered dramatically over the research period due to the GGP. Farmland was turned mostly into forestland and grassland, and forestland and grassland areas progressively grew. (2) The ESVs in Shaanxi Province were USD 3802.82, 3814.90, 3836.20, and 3806.50 billion in 1990, 2000, 2010, and 2020, respectively. The most value was supplied by hydrological management, while water resources provided the lowest value. Forestland and grassland were the most valuable land-types in high-value locations, whereas built-up land was the most valuable land-type in low-value areas. (3) While the GGP has increased the ESV of forestland and grassland, it has harmed the acreage of other land-types, resulting in a decline in the total ESV in Shaanxi Province.

“…A similar adverse effect of increasing imperviousness on bird richness is evident in Dhaka. During the last two decades, a rapid shift in land cover features in this city has been noted by several studies (Sultana et al 2009, Byomkesh et al 2012, Jaman et al 2020, Rahman and Szabó 2021. Because urbanization in Dhaka is messy, like in many other South Asian cities (Ellis and Roberts 2016), unplanned expansion has already resulted in a decline in the proportion of green spaces and water body areas (Appendix 4, Image A4.4; Sultana et al 2009.…”

“…In Dhaka, existing ecological research has mostly focused on land cover change (Sultana et al 2009, Byomkesh et al 2012, Jaman et al 2020, Rahman and Szabó 2021, climatic effects and environmental pollution (Dewan et al 2021, Uddin andJeong 2021), and economic and social aspects (Zinia and McShane 2018). Several such studies have reported that the high intensity of population growth and extent of human settlement https://www.ecologyandsociety.org/vol27/iss1/art19/ have already caused a significant alteration in abiotic conditions, deficiency in natural vegetation cover, and loss in green spaces and wetland areas in this city (Sultana et al 2009, Byomkesh et al 2012, Jaman et al 2020, Dewan et al 2021.…”

Factors driving urban biodiversity remain poorly documented in the rapidly growing tropical cities. We investigated the drivers of bird diversity in Dhaka city, located in Bangladesh, South Asia. Using existing sources, we compiled a bird checklist of the city. Next, we conducted point-count surveys of birds across its urban areas. Using field survey data, we investigated urban land cover and socioeconomic effects on resident bird species richness and abundance by applying linear regression modeling. Additionally, we performed path analyses for an in-depth understanding of direct and indirect relationships between selected urban land covers and socioeconomic variables and bird diversity. Our linear regression model assessment indicated that land cover is significantly shaping resident bird richness, whereas bird abundance is influenced by the combined effect of land cover and socioeconomic factors. Specifically, an increasing proportion of imperviousness was causing low bird richness, whereas bird abundance increased in areas with high habitat heterogeneity and proximity to parks but decreased with rising poverty (one of the major socioeconomic issues in Dhaka). Causal path analysis revealed that socioeconomic status, directly as well as indirectly mediated by urban land cover factors, affects bird diversity. Most importantly, it confirmed the greater significance of the direct negative effect of imperviousness on bird richness and of poverty on bird abundance in urban areas. This, in turn, suggests that bird diversity is favored by heterogeneous habitats and in wealthier neighborhoods. Nevertheless, overall bird diversity in Dhaka city was largely made up of generalist species of low conservation concern; species of the omnivore feeding guild and with ubiquitous habitat preferences were the most abundant. Our results represent the first step toward understanding drivers of biodiversity patterns across urban areas of tropical megacities within South Asia and contribute to a solid basis for urban biodiversity planning in the region.
