Accessibility of Park Green Space in Wuhan, China: Implications for Spatial Equity in the Post-COVID-19 Era

International Journal of Environmental Research and Public Health, Год журнала: 2022, Номер 19(9), С. 5440 - 5440

During the COVID-19 pandemic, people have seen precious value of park green space for health. In post-COVID-19 Era, it is essential to understand different needs and expectations communities use space. A myriad previous studies focused on whole city’s demand space, while few examined spatial equity from a supply-demand perspective. This paper aims investigate differences in accessibility among ages at community scale. Specifically, better evaluate account travel choice, we compared effects two-step floating catchment area (2SFCA) method containing distance decay functions (i.e., improved 2SFCA methods) by considering traffic network scale addition, methods with traditional 2SFCA. study investigated 1184 total population 6,468,612 central urban districts Wuhan. The results showed that high accessible were concentrated center along Yangtze River. outperformed 2SFCA, presented smoother gradient information. It was revealed over half communities’ levels did not match their density. Inequality found ages, especially youth (Gini coefficient as 0.83). difference age structures implies need integrate planning into Era.

Agricultural production efficiency estimation and spatiotemporal convergence characteristic analysis in the Yangtze River Economic Belt: A semi‐parametric metafrontier approach

Land Degradation and Development, Год журнала: 2023, Номер 34(15), С. 4635 - 4648

Опубликована: Июль 4, 2023

Abstract The sustainable development goals regard improving agricultural production efficiency (APE) as the main method to solve food security problems. Based on geographical cognition, combined with functional positioning, we used meta semi‐parametric linear programming and spatial convergence models analyze spatiotemporal characteristics of APE in Yangtze River Economic Belt from 2000 2020. results show that (1) under framework metafrontier analysis, increases while maintaining an olive‐shaped stable structure “sharp at both ends wide middle”; (2) efficiencies areas middle reaches has obviously declined compared non‐agricultural areas; (3) non‐spatial factors jointly drive convergence. research can provide references for clarifying evolution law regional agriculture formulating differentiation macro policies.

The Effect of Place-Based Policy on Urban Land Green Use Efficiency: Evidence from the Pilot Free-Trade Zone Establishment in China

Land, Год журнала: 2023, Номер 12(3), С. 701 - 701

Опубликована: Март 17, 2023

The improvement of urban land green use efficiency is significant in promoting sustainable development. As an important place-based policy China, the pilot free-trade zone establishment has exerted a profound impact on economy and society. Meanwhile, issue whether can improve or not missing from prior literature, which concern this study. Specifically, based super-efficiency slacks-based measure model, we first 279 cities China 2011 to 2019 then multi-period difference-in-differences method investigate causal effect efficiency. results show that significantly improved efficiency, especially eastern cities, coastal with high economic development level. Further, there exists spatial spillover This study implications for optimal allocation deployment policies, serving structural upgrading carbon neutrality vision.

Spatial data infrastructure as the means to assemble geographic information necessary for effective agricultural policies in Pakistan

Information Development, Год журнала: 2024, Номер unknown

Опубликована: Апрель 3, 2024

Geospatial information is used to regularly estimate agricultural production for improving food security and economic indicators. Particularly, such estimates are vital agriculture-based economies like Pakistan. However, poorly managed spatial causes inaccurate estimates. Consequently, public policies as agriculture often remain unsustainable secure enough uplift the rural economy. Against this backdrop, main objective of paper identify types datasets, categorize them based on relative importance, propose a framework seamlessly disseminate those datasets policy-makers in To do so, first all, literature reviewed preliminary list data prepared. Then we make use Delphi survey prepare final data. The also categorized into most important, very important datasets. results study revealed that four include; hydrological, land use, census, meteorological category include six datasets; cadaster, crops, soil, pest disease, natural hazards, climate change three remote sensing, research, agroecological zones fall under Through implementing SDI, identified can be made available one place find access inform policies, concludes.

Unveiling the explanatory power of environmental variables in soil organic carbon mapping: A global–local analysis framework

Geoderma, Год журнала: 2024, Номер 449, С. 117011 - 117011

Опубликована: Авг. 26, 2024

Soil organic carbon (SOC) is a critical component that affects soil quality and global cycling. Current SOC mapping approaches are based on the spatial stationarity relationship of formation processes. Nevertheless, pattern consequence different soil-forming factors processes operate at scales. In this work, we hypothesized covariation environmental variables might differ spatially, proposed (whole area) local analysis framework aimed to enhance our comprehension explanatory scale variation. This primarily incorporates Geographically Weighted correlation Multi-scale Regression (MGWR) model. With 216 farmland topsoil samples collected from Qilu Lake watershed in Yunnan Province, China (area 354 km2), explored both relationships between verify feasibility framework. Results showed power variation scale-dependent. Our revealed certain variables, which may explain variations SOC, often overlooked due their insignificant with (p > 0.05). For example, case study, porosity two landscape metrics characterize anthropogenic land use patterns can effectively SOC. They improved model performance MGWR, but not significant. The highlights necessity investigating scale.
