Inquiring the impact of rural-urban migration, construction sector, and agriculture irrigated land on environmental degradation: insights from urbanized Asian countries.

Abstract

The present study investigates the influence of rural-urban migration, construction sector share, and agriculture-irrigated land on environmental quality in urbanized Asian nations. For analysis, panel data from seven highly urbanized economies from 1996 to 2020 is utilized. The study employed an augmented mean group (AMG) estimator to find short and long-run results. The empirical discoveries depict that rural-urban migration increases energy demand in urbanized areas and significantly contributes to deteriorating environmental quality. The findings also reveal that the expansion of construction sectors is a significant source of high cement production, which also increases carbon emissions and environmental pollution by increasing the concentration of particulate matter in the atmosphere. The findings also exposed the role of agriculture-irrigated land, contributing to carbon emissions in urbanized Asian economies. The study also investigated the impact of the square term of irrigated agricultural land on environmental deterioration, revealing that adding agricultural land will further intensify environmental degradation by increasing carbon emissions in the atmosphere. A policy framework to reduce environmental damage in Asian economies caused by rural-to-urban migration, the building industry, and irrigated agricultural land was recommended based on the study's findings.
