People worry about landslides on Lam River banks

Dozens of hectares of alluvial land were "wiped out"

Farmers in Tan Long hamlet, Long Xa commune, Hung Nguyen district, Nghe An province are heartbroken to see layers of fertile alluvial soil being washed away after each flood season. According to local people, a few years ago, the alluvial area was hundreds of meters wide, enough to grow vegetables, corn, and peanuts. But now, the river has encroached deep into the mainland, in many places it has "swallowed" more than 30 meters. Ms. Tran Thi Thu, Tan Long hamlet, Long Xa commune shared: "Every year we have to retreat a few dozen meters to grow crops. After finishing a crop, we worry about whether the land will still be there next season. Now, my family only dares to grow vegetables on a small area and choose short-term varieties to harvest before the water rises again."

In fact, the entire Lam River alluvial plain stretching through Hung Nguyen and Nam Dan districts has a total area of ​​up to thousands of hectares, which is very favorable for agricultural development, especially high-tech agriculture. However, in the past 5 years, dozens of hectares of land have been eroded, many places have been completely "wiped out". Faced with this situation, local authorities have implemented a number of temporary solutions such as planting wave-blocking trees and planting acacia at landslide sites. However, according to assessments, these biological measures are not strong enough to cope with large flows, especially during the rainy season.

Some sections of the riverbank have been invested in building stone embankments, bringing clear results in preventing erosion. However, many sections that have not been embanked continue to be eroded every day. "The sandy loam layer is weak, just a few big waves or when the tide recedes, the soil will fall into the river again," worried Mr. Nguyen Van Ha, a resident of Long Xa commune.

In addition, according to local residents, another cause of increasingly serious erosion is sand mining on the Lam River. Despite planning and management, the impact of sand mining has changed the flow, contributing to faster riverbank erosion. People in Long Xa earnestly hope: “We don’t need much, we just want a solid embankment to protect the farmland. The alluvial plain is the source of livelihood for hundreds of households, losing land every year means losing effort, money and safety.”

Need a solution soon

In a similar situation, in Trung Phuc Cuong commune (Nam Dan district) - an area bordering Long Xa, the corn and bean fields of the people are now just patches of erosion along the river. "We have reported this situation to the district and province many times, hoping for a solid embankment system, but so far there has been no significant change," said a commune official. However, to implement a solid embankment system, a large investment capital is needed and must be assessed and approved by competent authorities. While waiting for policies from the Central and the province, many localities are still trying to "save themselves" by manual measures such as temporary reinforcement, increased patrols, and warnings to the people.

Mr. Ho Van Chien - Vice Chairman of Long Xa Commune People's Committee said that the commune has an area of ​​about 150 hectares of alluvial land, serving production, which is quite fertile. However, every year due to flooding, in the past time, about 10 hectares of land have been washed away. Although the locality has planted wave-blocking trees at landslide sites, this measure has not brought about clear results. Over the years, a number of stone revetment projects have been implemented at key locations, however, areas that have not been revetmented continue to suffer serious landslides.

The landslide situation on Lam river bank is not only a story of loss of productive land, but also a matter of security and living environment for people. Preventing landslide on Lam river bank is an urgent problem for both local authorities and functional departments of Nghe An province.
