Comparing the process of converting land use purposes between socio-economic regions in Vietnam from 2007 to 2020

Abstract

Reporting land use changes over time is important for evaluating land resource management. This study applied GIS technology to determine land use fluctuations for the entire mainland territory in Vietnam. In particular, the research focused on two main issues: (1) spatial fluctuations of some main land groups in Vietnam, and(2) the rate of land use change in socio-economic regions in the two periods 2007–2016 and 2016–2020. Research results showed that the Forests land group showed a growth of over 14% and spatial fluctuations took place in all regions, except for two regions with little change in this land group: Red River Delta (RRD) and Mekong River Delta (MRD). Meanwhile, crops decreased by over 16% from 2007–2020 and appeared heavily in the Northern Midlands and Mountains (NMR), North Central and Central Coast regions (NCR), and Central Highlands region (CHR). Urban land group increased by 3% during 2007–2020. The speed of land use conversion also showed different results between economic regions and inthe two research periods. The results showed that the recent research period witnessed a higher rate of land use conversion in the regions compared to the period 2007–2016. In particular, the NMR region showed that the conversion rate was the largest in both stages.
