Heavy rains create land slides that leave thousands killed and homeless in the Philippines each year.

But now eco-friendly nets have been created by one local entrepreneur to prevent erosion and to stop storm devestation.

His key ingredient — coconuts.


Justino Arboleda has taken one of the most ubiquitous items in the Philippine islands and put it to use for a good cause.

The common coconut is being used to produce eco-friendly nets to combat landslides that devastate the islands each year as a result of heavy weather.

In 2005 alone, 66-thousand people in several northern provinces were left displaced by storms — their homes destroyed.

Arboleda, an agricultural engineer, developed the product to combat such devastation.

SOUNDBITE: (English)
“We experience a lot of rain, we experience a lot of typhoons, and due to that, we have a lot of erosion and mountain collapsing and slopes failing because of very strong rains so we thought of being able to develop a product using coconut fibers to prevent erosion in the country.”

Since its development the coconet has been used in many real estate developments in the Philippines.

The technology has also been applied in riverbank rehabilitation efforts in Germany, Japan and the US.

It is also being tapped for slope protection along highway construction projects like this one in the province of Zambales.

Engineers familiar with the coconet say it’s the most efficient way to control soil erosion.

SOUNDBITE: (English)
“This is the most efficient…” in the modern construction industry, especially in slope protection. It can prevent soil erosion in the mountains or any construction areas. Beside from being very efficient, it is cheaper than the rest of the materials. And the technology is far better than the rest because we consider this ecological friendly.”
