Published: Sept. 10, 2024

Particulate matter with a diameter of 2.5 microns or less ( PM2.5 ) is significant type air pollution that affects human health due to its ability persist in the atmosphere and penetrate respiratory system. Accurate forecasting particulate crucial for healthcare sector any country. To achieve this, current work, new time series ensemble approach proposed based on various linear (autoregressive, simple exponential smoothing, autoregressive moving average, theta) nonlinear (nonparametric neural network autoregressive) models. Three models are also developed, each employing distinct weighting strategies: equal distribution weight among all single (ESME), assignment training average accuracy errors (ESMT), validation mean measures (ESMV). This technique was applied daily id="m3">PM2.5 concentration data from 1 January 2019, 31 May 2023, Pakistan’s main cities, including Lahore, Karachi, Peshawar, Islamabad, forecast short-term id="m4">PM2.5 concentrations.

How Financial Development Is Driving the Growth and Environmental Dimensions of Sustainable Development in Africa: Heterogeneous Analyses

Sustainability, Journal Year: 2024, Volume and Issue: 16(21), P. 9284 - 9284

Published: Oct. 25, 2024

Globally, we face a policy dilemma between desiring more economic growth and safeguarding the deteriorating ecosystem, which have an apparent trade-off. Consequently, financing often comes with strong concerns for ecological implications, is yet to be empirically resolved. Hence, current study examined environmental effects of financial development from three angles, each robust indicator, comprising index, institution market index. The scope this was in 30 selected African countries 1996 2021. This extends frontier knowledge by estimating moderating roles regulatory quality digitalization coupled other control variables: renewable nonrenewable energy, government expenditure, trade openness, foreign direct investment. empirical evidence relies on estimators such as common correlated (mean group), system-generalized method moment, moment quantile regression. findings reveal that propels but detriment ecosystem. However, when interactive are considered, negative externalities growth-induced reduced. Furthermore, variables energy investment promote without escalating damage. contrast propel at expense system. Policy recommendations balance trade-off two measures put forward based research outcomes.

Deconstruction of green product innovation drivers for regional export-oriented industrial enterprises in China: the product space perspective

Humanities and Social Sciences Communications, Journal Year: 2024, Volume and Issue: 11(1)

Published: Oct. 26, 2024

Achieving green economic growth requires enterprises to develop and promote products that balance environmental protection, intensive resource utilization, sustainable development. However, under the externality assumption, market is often faced with challenge of insufficient supply. Based on 2004–2018 panel data covering regional industrial in 30 provinces China, this study empirically tests composite driving mechanism effect an increase production capacity, organizational factors, policies product innovation (GPI) export-oriented (REIEs). This finds capacity directly drives improvement REIEs' GPI level, technology level degree human capital accumulation are indirect channels between increases innovation, regulations credit have a positive moderating influence increasing GPI. Further threshold regression analysis reveals foreign direct investment, digitization, trade openness inverted U-shaped promoting proportion local government expenditure shows diminishing marginal utility

Quantifying the Effect of Land Use and Land Cover Changes on Spatial-Temporal Dynamics of Water in Hanjiang River Basin

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(22), P. 4136 - 4136

Published: Nov. 6, 2024

As a vital part of the geo-environment and water cycle, ecosystem health human development are dependent on resources. Water supply demand influenced significantly by land use cover change (LUCC) which shapes surface ecosystems altering their structure function. Under future climate scenarios, LUCC may greatly impact regional balance, yet is still not well understood. Therefore, examining spatial relationship between yield services crucial for optimizing resources informing sustainable policies. In this study, we focused Hanjiang River Basin used patch-generating simulation (PLUS) model, coupled with Integrated Valuation Ecosystem Services Tradeoffs (InVEST) to assess under three Shared Socioeconomic Pathway Representative Concentration (SSP-RCP) scenarios. For first time, considered changes in socio-economic indicators using correction factors ARIMA projections. The was explored approach, LUCC’s effects balance also discussed. Results indicate that: (1) patterns similar scenarios from 2030 2050, varying levels decrease cropland significant growth built-up areas, increases 6.77% 19.65% (SSP119), 7.66% 22.65% (SSP245), 15.88% 46.69% (SSP585), respectively, relative 2020; (2) trends produced similar, overall risks all downward trend. continues decline, 3 will 96.275×108t, 81.210×108t, 84.13×108t 2020, respectively; while decreases 2040 rises 2050; (3) Both distributions exhibit correlation, distribution hotspots similar. well-matched, an supply-demand ratio greater than 1.5; (4) can either increase or yield.
