The present study investigated how both climatic and socioeconomic variables affect means and variations in crop yield. We examined factors that affect the yields of two major crops, wheat and maize, cultivated in different seasons in Madhya Pradesh, India. For empirical analysis, we employed the Just and Pope production function, covering the period from 1999 to 2017 based on the latest district-level available data of Madhya Pradesh. An increase in rainfall enhanced the mean yield of both crops in Central India, showing the yield of these crops is highly dependent on rainfall. Average temperature and number of extreme cold days adversely affected the wheat yield in the region. Furthermore, an increase in fertilizer consumption raised mean crop yield, but it was not uniform, because this leads to an increase in variation of crop yields. The findings also confirmed the presence of an inverted ‘U’-shaped relationship between the mean maize yield and rainfall. However, there was a ‘U’ shaped relationship between mean wheat yield and temperature. Surprisingly, irrigation showed a differential impact on mean yield in different seasons. Normally, irrigation is a risk reducing input and diminishes variance in yields. These results provide policy insights to state and local governments for adaptation measures against climate change to protect the mean yield and control variations in yield of these major crops in the central part of India.</p></div>","PeriodicalId":36164,"journal":{"name":"Asia-Pacific Journal of Regional Science","volume":"9 3","pages":"807 - 830"},"PeriodicalIF":1.7,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite sustained global efforts toward achieving Sustainable Development Goal 13 (climate action), most countries in the region are still hampered by resource dependency, a lack of effective policy implementation, and ongoing ecological pressures. This paper looks at how information and communication technology (ICT), human development (HD), military expenditures (ME), and renewable energy (REC) affect the environmental quality (ENQ) based on three indicators, i.e., carbon dioxide emissions (CO<sub>2</sub>e), ecological footprint (EFP) and greenhouse gas emissions (GHGe) in ten MENA countries between 2001 and 2022 within the Environmental Kuznets Curve (EKC) framework. Employing the Pooled Mean Group (PMG) estimation model, the results show that although ME and NREC worsen the environment by increasing CO<sub>2</sub>e, HD, ICT and REC improve ENQ by reducing CO<sub>2</sub>e in the long run. However, HD, ICT, REC, NREC and FDI worsen the environment by increasing EFP, while ICT improves the environment by mitigation. Meanwhile, HD, ME and REC decrease GHGe, while ICT and NREC increase them. Furthermore, all three models support the EKC hypothesis in the MENA Region. Based on the overall findings, MENA nations must establish a conducive policy framework by adopting green growth strategies, promoting clean energy, leveraging ICT for sustainability, integrating eco-friendly practices into military operations, and allocating defense budgets to environmental initiatives, all of which are crucial for advancing climate action in the region.</p></div>","PeriodicalId":36164,"journal":{"name":"Asia-Pacific Journal of Regional Science","volume":"9 3","pages":"773 - 805"},"PeriodicalIF":1.7,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the relationships between income and coffee consumption across different regions to analyze whether coffee behaves as a normal good. Using an unbalanced panel dataset from 53 countries, we incorporated key economic variables including Gross Domestic Product (GDP) per capita, coffee and tea consumption, and the prices of ground coffee and tea. A fixed-effects regression model was employed to assess the impact of income variations on coffee intake. The findings revealed significant regional disparities. For the European and African & Middle Eastern Regions, income showed a positive effect on coffee consumption when grouped with all variables. For the Asia–Pacific (APAC) and American regions, income within the regression showed no statistical significance whatsoever. Therefore, income appears, for half the regions, to be significant in determining coffee consumption, i.e., the more money one has, the more coffee they are able to consume, which reiterates that coffee is a normal good. These results contribute to the existing literature by providing a comparative regional analysis of income-driven coffee consumption. The findings also have practical implications for coffee producers, policymakers, and businesses seeking to understand market demands. Understanding regional coffee trends can support demand forecasting and pricing strategies. However, future studies should also examine consumer behavior and marketing dynamics. </p></div>","PeriodicalId":36164,"journal":{"name":"Asia-Pacific Journal of Regional Science","volume":"9 3","pages":"869 - 902"},"PeriodicalIF":1.7,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These datasets provide insights into community participation, volunteering, perceptions of safety and inclusion, and electoral engagement. We draw two main conclusions from our synthesis. First, although migrants arrive with limited local social capital, they gradually build bonding, bridging, and linking, social capital over time. In addition, reported experiences of discrimination decline with longer residence. However, pooled survey data reveal variation in these patterns across time. Second, social capital investment is shaped by the spatial distribution of ethnic groups.

Load capacity factors were employed as an innovative metric to assess ecological demands relative to biocapacity. Utilizing a non-parametric Method of Moments Quantile Regression (MMQR) approach on panel data spanning 1993–2023, the findings revealed that environmental policy stringency, energy intensity, renewable energy consumption, and foreign direct investment have positive and significant impacts on environmental sustainability across heterogenous quantiles. Conversely, economic growth and non-renewable energy consumption exerted negative and significant influences on environmental sustainability across most quantiles. In conclusion, we recommend prioritizing policies that promote a transition from non-renewable to renewable energy sources through incentives such as tax reductions and subsidies.

Therefore, this study classified land use and land cover, then evaluated urban landscape dynamics through the zone-wise distribution of built-up areas, and computed Shannon’s entropy alongside landscape metrics such as Number of Patches (NP), Largest Patch Index (LPI), Edge Density (ED), Mean Euclidean Nearest Neighbor Distance (ENN_MN), Contagion (CONTAG), and Shannon’s Diversity Index (SHDI). Furthermore, we delineated urban growth typologies using the Landscape Expansion Index (LEI) and compared the results of each technique with the established urban growth theories. Results indicated that the built-up area increased from 40.97 km<sup>2</sup> in 1990 to 183.86 km<sup>2</sup> by 2024, with burgeoning sprawl predominantly occurring in peripheral buffer zones further away from the urban core. This revealed a dual growth trajectory: the urban core demonstrated coalescence through infilling, while peripheral regions experienced urban sprawl, marked by increased dispersion and outlying growth as indicated by a Shannon entropy value exceeding 0.5. Landscape metrics further elucidated these dynamics with increases in ENN_MN and LPI reflecting clustering in core areas, whereas increases in NP, LPI, ED, SHDI, and decreased in CONTAG suggesting dispersion in peripheral areas. Thus, diffusion and coalescence occurred simultaneously.
