DEVELOPING A EROSION MAP OF SMALL CANAL IN AN GIANG PROVINCE - PARTICIPATORY METHODOLOGY

Abstract

This study focuses on developing a community-participated erosion map for the small river and canal system in An Giang province. The new approach integrates secondary data from reports, documents, and satellite imagery with inputs from local managers and the communities through workshops, field surveys and data verification processes. The research results have successfully developed a map of erosion locations on the small river in An Giang province with data updated to February 2024. The erosion map has identified identified 279 erosion locations categorized into three levels: Minor, moderate and severe. Severe erosion points were accounted for 31.2% and concentrated in areas such as Cho Moi, Chau Thanh and Tinh Bien district. The results of the study provide detailed information on the current status of erosion in An Giang province, contributing to raising public awareness of erosion risks and response measures. Participatory mapping methods will effectively support risk management, infrastructure planning and other issues.
