DENR orders bamboo planting along Cagayan River to prevent floods

MANILA, Philippines – Department of Environment and Natural Resources (DENR) Secretary Roy Cimatu has ordered the planting of bamboo trees along the banks of Cagayan to help prevent a repeat of the floods that submerged parts of Cagayan and Isabela provinces during the onslaught of Typhoon Ulysses.
The DENR said Cimatu issued that directive following a meeting with the Build Back Better Task Force created by President Rodrigo Duterte to oversee the rehabilitation of areas devastated by recent typhoons.
Cimatu co-chairs the task force with Public Works and Highways Secretary Mark Villar.
Cimatu told the DENR regional offices in Cagayan Valley, Central Luzon and CALABARZON to ensure the availability of bamboo planting materials and to identify areas along the river channels that are most suitable for bamboo propagation under the government’s Enhanced National Greening Program.
The DENR chief said they picked bamboo as it is ideal for stabilizing riverbanks given its high survival rate.
“The survival rate of bamboo is much higher and it has a faster growth rate compared to other trees,” he said, adding that bamboos also have the potential to be “a sustainable source of livelihood for the people of Cagayan Valley while protecting the integrity of Cagayan River.”
In the same meeting, Department of Trade and Industry Undersecretary Blesila Lantayona said the DENR’s move to plant bamboo trees offers an opportunity to look into the economic importance of bamboo.
Lantayona said the DTI has been producing engineered bamboo, but its facilities cannot operate at full capacity because there is currently a lack of bamboo supply.
“Cimatu’s push to mainstream engineered bamboo as a major alternative to timber will finally enable the full implementation of Executive Order (EO) 879,” she said.
Under EO 879, at least 25 percent of the annual requirement of school desks and chairs of all public elementary and secondary schools nationwide should be made of bamboo.
It also directs the DENR – through its Forest Management Bureau, Mines and Geosciences Bureau and Laguna Lake Development Authority – to use bamboo as the planting material for at least 20 percent of its annual reforestation and rehabilitation areas.
“This should be done especially in provinces and towns which are engaged in or have the potential to engage in bamboo-based industries or where trees are difficult to grow because of poor site quality, susceptibility to erosion or adverse and steep gradients,” the DENR said.
“We will look into the old river and how the river became narrower through the years,” Cimatu said.
“We will restore the original width of the Marikina River,” he added.
At the same time, Cimatu said the DENR will look into the complaint of the Marikina City government over the alleged reclamation project along the river, which has not secured an environmental compliance certificate (ECC) from the environment department.
“Definitely, there should be no reclamation. I will really implement the easement law,” he said.
Cimatu said he has directed the DENR-National Capital Region office to look into the non-issuance of ECC, the reclamation, and the retaining wall built along the riverbanks.
MANILA, Philippines – Environment Secretary Roy Cimatu wants an immediate assessment of the major waterways like rivers across the country to determine which of them needs to undergo dredging.
Environment Undersecretary Jonas Leones said the Department is planning a dredging operation in the Cagayan River which carries water from Nueva Ecija to Appari.
The recent onslaught of Typhoon Ulysses caused the river to overflow its banks and submerge nearby areas like Cagayan and Isabela.
In his last briefing with President Rodrigo Duterte, Cimatu said the government will not shell out any amount for the project but it will gain from it instead.
“It will be really a request of the governor to allow a contractor to clean or to dredge the river and at the same time in exchange of that, he has allowed to sell this sand,” Cimatu said.
“But they have to pay as much as what the mining company is paying for – 4% excise tax as a revenue of the government,” he added.
Meanwhile, the Laguna Lake Development Authority (LLDA) is studying the proposed plan to rehabilitate the lake.
According to the agency, the Laguna Lake is now about 2.5 meters deep as compared to 5 meters that the locals used to observe in the past.
According to LLDA Department Manager III Emeterio Hernandez, they have to remove at least 2 meters of sediments or silt from the lake, especially at the opening section and the western section to make space for water flowing from nearby waterways like Marikina River.
“Ang ibang common term dyan is parang batya na sinasahod niya lahat ng ulan na nanggagaling sa ating mga watershed,” Hernandez said.
[The common term for that is like a basin that catches the rain coming from the watershed.]
“So kung ang batya natin ay medyo mababaw na, so ineexpect natin na kaunting dagdag lang ng tubig mag ooverflow siya,” he added.
[So if the basin becomes shallow, with only a small amount the water will overflow.]
No government funding will be required for the dredging operation, Hernandez said.
Once approved, the project is expected to commence next year and will be completed hopefully within the next 3 to 5 years. MNP (with reports from Rey Pelayo)
