Super typhoon Yagi (typhoon No. 3) with winds of level 16, 17 and its circulation "ravaged" across 26 northern provinces and cities, causing hundreds of deaths and missing people, economic damage exceeding 80,000 billion VND. The most tragic were the landslides that submerged entire villages with dozens of houses, hundreds of people and livestock in mud, such as in Phin Chai 2 village, A Lu commune, Bat Xat district or Lang Nu village, Phuc Khanh commune, Bao Yen district, both in Lao Cai province...
After the storm, the risk of landslides still lurks. Traffic road in A Lu commune, Bat Xat, Lao Cai.
Landslides and landslides have occurred many times over the years, but those were times when the ground lost its footing and slid, or collapsed. This time it was mud, slushy mud. In the Yagi disaster, in many places there was a sudden explosion that shook the mountains and forests, then a giant column of mud shot out from the mountainside, rolling down and engulfing everything.
According to experts, environmental researchers, and geologists, one of the causes is deforestation. Primary forests with their complex, multi-layered, multi-canopy natural structures play an important role in reducing the negative impacts of natural disasters and preventing rainwater from pouring directly onto the ground.
The ancient trees have roots tens of meters deep, intertwined, firmly maintaining the connection between soil and rock, between the surface layer and the deep layer, forming a stable and solid block that retains most of the rainwater, slowly seeping into the ground to form underground water, only a small amount of rainwater flows on the ground, rarely enough to cause flash floods.
In many localities, from the northern mountains to the Central Highlands, most ethnic minorities have forest worship ceremonies, a sacred religious ritual of those who live by the forest and return to the forest when they die; there are very strict customary laws, severely punishing anyone who enters the sacred forest to collect firewood or cut trees. From generation to generation, the elderly still remind the young: We must protect the forest so that the water can flow, so that life can flourish forever. Without the forest, all species will leave. Only those who remember this saying will become human.
However, in the general picture, a painful reality is that after many decades, some of the forests have been exploited without proper planning, some have been illegally cut down by people for farming and making a living; some have been converted to unsuitable crops; and some have been damaged by the abuse of hydropower plants, leading to... the forests gradually disappearing.
After the flash flood, in Trinh Tuong commune, Bat Xat, Lao Cai.
Deforestation, water-saturated soil, loose connections, soft soil and rocks, combined with flash floods that cause loss of footing, mountains will collapse, hills will collapse, hundreds of thousands, millions of cubic meters of soil and rocks from above slide down, sweeping away everything in its path.
According to the Ministry of Agriculture and Rural Development, in 2023, the national forest coverage rate will reach 42.02%, but it will mainly be low-canopy production forests, exploited according to the tree life cycle. Typhoon Yagi alone damaged 170,000 hectares of forest in 13 northern localities.
With the support of the central government and the cooperation of people across the country, localities are urgently overcoming the consequences of storms and floods, quickly stabilizing people's lives. This is considered a key and urgent task, especially for party committees, authorities, and functional forces at the grassroots level. However, in addition to rebuilding people's lives, natural forest restoration must also be prioritized in the short and long term.
Along the roads to Bao Thang, Bao Yen, Van Ban, Bat Xat districts of Lao Cai province, the primeval forests have almost all been lost, and after the floods, many serious landslides have appeared. To have natural forests with many layers and canopies capable of mitigating natural disasters and contributing to preventing an ecological crisis will take decades or even hundreds of years. This is a very difficult task, but it cannot be avoided and must be done with the experiences and lessons learned from the consequences of storms and floods due to deforestation.
More than ever, localities with forests need to have a sustainable development strategy, in which ensuring livelihoods and lives for the people, and orienting local socio-economic development cannot be separated from protecting the environment in general and the forest ecosystem in particular. Forest planting, restoration and exploitation must be fundamentally synchronous, harmoniously solving the economic and environmental values of forests, putting the goal of protecting the environment and combating climate change first with strict regulations and strict enforcement of laws on forest protection.
In addition, the development planning of industries must be recalculated appropriately for the common benefit, between the exploitation of mineral resources and forest resources, water resources; between hydropower development and the goal of forest preservation, protection of agricultural and forestry resources...
