Rapid urbanization threatens the natural capital of Dhaka city, affecting the delivery of ES through changes in land use and land cover. We used vertical growth (VG), nighttime light data (NTL), and population density (PD) as standard urbanization indicators alongside technomass, a three-dimensional indicator, to evaluate the degree of urbanization as a continuous spatial process. We modeled the spatiotemporal relationships between urbanization degrees and ES using the ecosystem service value (ESV) dataset applied in Dhaka, with regional modified value coefficients. Results from the geographically weighted regression (GWR) model showed that technomass emerged as a more appropriate indicator to analyze urbanization for ESV analysis (<em>r &gt;</em> 0.61), followed by NTL (<em>r &gt;</em> 0.56), and PD (<em>r &gt;</em> 0.54) across all zones from 2000 to 2021. We observed a 68.34% decrease in net ESV, equivalent to $245.88 million (in 2021 USD), from 2000 to 2021. This decline was driven by the conversion of water bodies (−70.93%), agricultural land (−60.08%), forest and vegetation (−70.18%) into urban built-up areas and other uses. In contrast, net technomass increased by 243.11% due to the city's vertical growth. The digital building height (DBH) model revealed that the built-up area had expanded by 94.94% over the study period, with an average annual growth rate of 4.52%. Significant correlations (<em>p</em> &lt; 0.05) were observed between ES and urbanization. The rural-urban fringe area exhibited the most significant increase in urbanization (<em>r</em> &gt; 0.90), along with a 440.47% growth in technomass. Our results provide insights into the impact of urbanization on ES, particularly at the regional scale, and have highlighted the importance of integrating VG and technomass for urbanization analysis.

Therefore, it becomes crucial disclosing the methodologies underlying any emissions accounting frameworks, together with any simplifications and assumptions, with the aim to produce reliable support on local measures and data- driven decision-making in the form of a trustworthy emissions inventory. This study aims at identifying divergences and potential gaps in two approaches for GHG emission inventories at local level complementing the results of previous studies.

However, perceived performance failed to meet participant expectations for all 33 outcomes and particularly for conservation and economic outcomes. Expectation-performance gaps were largest for conservation outcomes such as reduced illegal logging, economic outcomes including increased income, financial assistance, and employment, and sociocultural outcomes such as the constancy of children's school attendance. Successfully addressing these gaps will depend largely on external factors, such as government effectiveness in controlling illegal logging and investments in credit and education.

We first quantify the coupling coordination degree of the WEF nexus using the entropy weight TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. And then Ordinary Least Squares Multiple Linear Regression model is employed to explore the impact of the WEF nexus coupling coordination degree on food security. The findings show that an improvement of 1% in the coupling coordination degree of the WEF increases the total grain yield, per capita grain yield, grain yield per unit by 2.69%, 1.12% and 2.77%, respectively. It is also found that improvement of WEF coupling coordination is conducive to enhancing food self-sufficiency rate and stabilizing food price. And the increment in grain yield is achieved by increasing the effective irrigated area and agricultural machinery inputs. Furthermore, the heterogeneity analysis reveals that the effect of the WEF nexus on the total grain yield and per capita yield is more significant in the central region, and the improvement of grain yield per unit is more effective in the west.
