Slope stabilization and landslide protection are important parameters for community protection and infrastructure from natural damage. But irrespective of good features, they also cause environmental difficulties.
That environmental effect comes with the displacement of wildlife, loss of biodiversity, water quality problems, soil erosion and change of natural drainage design, carbon footprint, and air pollution from water.
Conventionally, stabilization methods come with non-sustainable operations. But now the world is becoming aware of the importance of eco-friendly solutions, and change towards environmentally conscious approaches is becoming famous. Check them out here:
Vegetative Cover
The simple, effective method for slope stabilization is the application of vegetative cover. Planting native vegetation on slopes helps for the connection of soil. The roots of plants work as a natural reinforcement system, a simple system that has soil in place and minimizes the chance of erosion.
With that, it is a low-cost option based on techniques and area. The feature for saving more is to go for famous, eco-friendly companies. Such as the famous Ground Stabilization Central Coast company is Ground Stabilization Services. They are based in Australia but also work at the international level.
With the stabilizing slopes, vegetative cover also enhances biodiversity, provides water retention, and minimizes surface runoff. First native plants are properly adapted for local climate, soil conditions, and ecosystem. They are not only resilient and low maintenance but also make habitats that support a larger range of flora and fauna.
Plant root systems provide the development of a healthy soil ecosystem. The roots release organic compounds in the soil, nourishing microorganisms.
That microbial activity increases soil fertility and makes dynamic conditions that are compatible with different soil-dwelling organisms, taking part in overall biodiversity.
The extensive root system of plants works as a natural barrier from water runoff. When it rains, roots help to bind soil components with each other, preventing them from being washed away. That binding effect increases soil water retention features, helping to absorb and hold more water.
As a result, water is slowly released into the ground, promoting a steady supply for local aquifers and avoiding a fast runoff.
Research has shown that vegetation with fallen leaves and plant debris has a natural mulching effect. The layers of organic materials on the soil surface work as a sponge, reducing water movement and also evaporation. As a result, increasing soil features for retaining moisture with time has advantages for both plants and the surrounding ecosystem.
The reduction in erosion translates to a reduction in surface runoff. Through stabilizing soil, vegetative cover reduces the effect of rainfall on a slope and avoids the creation of channels and gullies that cause increased runoff.
Coconut Coir Matting
Coconut coir matting is a simple but best solution for slope protection that uses natural fibers from coconut husks. Such as vegetative cover, these mates are biodegradable and provide good erosion control by stabilizing the soil surface.
Connection of coconut coir matting is a simple process. The mats can be applied directly on the slope and saved with stakes or biodegradable netting. With time, coconut fibers break and provide organic matter for soil and promote plant growth.
Gabion Walls with Native Stones
As compared to concrete or other non-biodegradable materials, gabion walls use wire baskets with native stones. These walls can avoid erosion, help water drainage, and enhance vegetation growth between the stones.
The use of native stones also provides materials that are easily available and do not need to be transported for longer distances. That reduces the environmental effects of construction.
Jute Netting
Jute netting is a type of erosion control blanket that offers instant protection for slopes to avoid soil erosion resulting from rain or wind. With that, they are made from jute, so they are more eco-friendly options than synthetic materials.
The other reason why hute netting is sustainable is since it decomposes with time. Like coconut coir, it left behind organic matter that was added soil. The open weave design of netting provides vegetation that further provides slope stability.
Terracing with Recycled Materials
Terracing is a time-tested technique that shifts steep slopes in a series of level platforms. These terraced steps minimize slop angle and force of water runoff and minimize erosion and landslides.
They also create additional planting areas, contributing to green spaces. With conventionally made bricks or concrete, an eco-friendly twist is added for terracing. That can be done with recyclable materials such as repurposed wooden pallets, discarded tires filled with soil, or recycled plastic blocks.
Final Thoughts
Now the time is to recognize that slope protection must not be at the expense of the environment we need to protect. Balancing the need for slope stabilization and landslide prevention with environmental conservation is possible through sustainable approaches, processes, and accurate planning and implementation.
