อนิเมชั่นโครงการพระราชดำริ "โครงการหญ้าแฝก อันเนื่องมากจากพระราชดำริ"

Summary

This video highlights the importance of using vetiver grass (Chrysopogon zizanioides) in soil and water conservation efforts. Introduced by King Bhumibol Adulyadej in response to soil erosion and degradation, vetiver grass helps prevent land erosion, improves soil fertility, and enhances water quality. The grass's deep, fibrous roots bind the soil, making it ideal for sloping terrains, and it absorbs harmful chemicals, improving water quality. Beyond conservation, vetiver is also used for animal feed, organic fertilizers, and essential oils. This initiative reflects the King’s dedication to sustainable environmental practices and his enduring legacy in preserving Thailand's land and resources.

Takeaways

• 😀 The use of Vetiver grass (หญ้าแฝก) was proposed by King Bhumibol Adulyadej to prevent soil erosion and improve soil conservation in Thailand.
• 😀 Vetiver grass is effective in protecting soil from erosion due to its deep and fast-growing roots that create a network to hold the soil together.
• 😀 The initiative was based on research from the World Bank, which encouraged using Vetiver grass to address soil degradation and loss of soil fertility.
• 😀 Vetiver grass is known by other names such as fragrant grass and true fragrant grass, with two main species found in Thailand: fragrant Vetiver and dryland Vetiver.
• 😀 Vetiver grass helps absorb harmful chemicals and pollutants in water runoff, thus improving water quality before it reaches rivers.
• 😀 The grass is primarily planted on sloped areas to reduce water runoff and soil loss, while also enhancing the soil's organic content.
• 😀 King Bhumibol's initiative led to widespread efforts, including distributing Vetiver grass to the public for soil and water conservation.
• 😀 The planting method requires closely spaced Vetiver grass clumps, which provide benefits such as controlling water speed, preventing soil erosion, and improving soil conditions.
• 😀 Vetiver grass also serves as a natural resource for animal fodder, organic fertilizers, and essential oils, offering additional economic benefits.
• 😀 The overall goal of the Vetiver grass initiative was to restore the land's fertility and contribute to the well-being of the Thai people, aligning with the King’s vision for sustainable development and prosperity.

Q & A

What is the significance of grass in soil conservation, according to the transcript?

Grass, specifically Vetiver grass, plays a critical role in soil conservation by preventing soil erosion, strengthening the soil, and improving water retention, thus maintaining the fertility of the land.

Who initiated the use of Vetiver grass for soil conservation in Thailand?

King Bhumibol Adulyadej initiated the use of Vetiver grass for soil conservation after recognizing its importance in preventing soil erosion and improving the environment.

What is the local name of Vetiver grass in Thailand?

In Thailand, Vetiver grass is locally known as 'Kra Thong' or 'Scented Grass'.

How many species of Vetiver grass are found in Thailand, and what are they?

Thailand has two species of Vetiver grass: 'Kra Thong Hom' (scented grass) and 'Kra Thong Don' (hill grass).

What were the steps taken to promote Vetiver grass for environmental preservation?

The steps included researching the benefits of Vetiver grass, collaborating with government agencies, conducting trials, and distributing the grass to the public for soil and water conservation.

What is the primary benefit of Vetiver grass' root system?

The root system of Vetiver grass grows deep and spreads extensively, forming a network that holds the soil together, preventing erosion and improving soil strength.

How does Vetiver grass contribute to water quality?

Vetiver grass helps in absorbing chemicals and pollutants from water before it flows into rivers, thus improving water quality.

What is the ideal type of land for planting Vetiver grass?

Vetiver grass thrives on sloped land, where it can act as a barrier to reduce water runoff and soil erosion.

What are the other uses of Vetiver grass aside from soil conservation?

Vetiver grass can be used for animal fodder, making compost, and producing essential oils, which can be extracted from its roots.

What are the long-term goals of implementing Vetiver grass in soil conservation projects in Thailand?

The long-term goal is to restore the fertility of the land, prevent soil erosion, improve water retention, and enhance the overall environmental health, ultimately benefiting the local population and ensuring sustainable land use.
