ZAMBOANGA CITY—It was a lesson about not learning a lesson.

Officials, were warned against wasting funds on artificially generating rain, declared cloud seeding a failure in easing the effects of the El Niño phenomenon in the city.


For 12 days until Feb. 28, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) and the Philippine Air Force conducted cloud-seeding operations at a cost of P1.3 million.

But Teotimo Reyes Jr., department manager of water production of Zamboanga City Water District (ZCWD), said the effects of the drought brought by El Niño had not eased.


“We did not see or experience any increase in the water stream, the ground [remains] very dry,” Reyes said.

In January, while the cloud-seeding operations were still being planned, vegetable farmers in the city already urged authorities to abandon the idea, citing past cases and amid an admission from a weather specialist that it might actually do more harm than good.

Annaliza Pabayos, a vegetable farmer in Barangay San Roque here, said that in the past, cloud seeding killed vegetables.

“I prefer to fetch water from the river to my field,” Pabayos said.

Celestiano Ahamad, a farm caretaker in Barangay Dita, agreed with Pabayos. “Cloud seeding dries up the leaves of corn, cassava and sweet potato,” he said.

Instead of spending for cloud-seeding operations, he said, the government should allocate fuel to farmers so they can use their water pumps to draw water from rivers.

Maribel Enriquez, Pagasa chief meteorologist here, said cloud seeding, indeed, increases the salt concentration in rain.


“If (cloud seeding-induced) rainwater falls on farms and through osmosis, the leaves will wither,” Enriquez said.

She said the problem could be avoided if the rain would go directly to water reservoirs or rivers because the unwanted salt could be eliminated by natural filtration.

Leonardo Ray Vasquez, general manager of ZCWD, also agreed that cloud seeding could be harmful to farms.

Vasquez, however, said cloud seeding could help raise the water level in the dam that ZCWD was using.

“Cloud seeding is not a sure hit due to wind movement but we have to fill the dam,” he said.

Enriquez said the weather bureau did its best to generate rain that could restore moisture in farms and bring water to households.

The amount of rain brought by 12 days of cloud seeding, however, was insufficient to bring relief to farmers and residents suffering from the drought.

Engineer Lorenzo Moron, Pagasa project coordination officer, said at least 100 sacks of salt had been used for the 12-day cloud-seeding operation.

Air Force Capt. Von Ryan Timbang, who led and supervised the seeding sorties, said they flew for an average of four two-hour sorties each day.

But Reyes said the situation had not improved.

He said water level at a dam in the Tumaga River, which the ZCWD uses, continued to decline and was now below the normal operating level of 74.2 meters. At least 80 percent of the water that ZCWD supplies comes from the river.

“That’s the water level for the last two days,” Reyes said.

As a result, water for the city’s consumers will be available for only seven hours a day, he said.

The destruction of farmlands is enormous, according to Diosdado Palacat, city agriculturist.

Mayor Ma. Isabelle Salazar said cloud seeding had done little to bring relief to the city.

She said residents should continue praying the “Oratio Imperata,” which the Church recommends for urgent situations.

Moron, however, said that although the cloud-seeding operations had not brought relief to the city, they helped Pagasa “increase and advance scientific understanding” about cloud seeding. “We were able to test the effectiveness of the seeding agent,” he said.

In the Autonomous Region in Muslim Mindanao (ARMM), regional Agriculture Secretary Alexander Alonto said the regional government had been conducting cloud-seeding operations as damage to crops was projected to reach P140 million.

He said that at least 27,000 farmers in the provinces of Lanao del Sur, Maguindanao, Sulu, Tawi-Tawi and Basilan were suffering losses from the dry spell and its other effects, including rodent attacks.

“We can’t really prevent the dry spell and we are asking farmers to brace themselves [for the disaster] and understand what the government can offer,” he said.

Alonto said the regional government had started distributing rodenticides and heat-resistant seeds to farmers.

ARMM Gov. Mujiv Hataman said the drought was also drying up government resources.

A farmer in the region was reported to have committed suicide after failing to borrow money he could use to tide him over until the drought was over.

“Hunger can really affect one’s sanity,” said Pombaen Karon, regional social welfare secretary.

Karon expressed alarm over the increasing number of families in ARMM that were going hungry as a result of the drought.

Hataman said the regional government was distributing relief packs to areas hit by the drought.

Abugantao Saidona, a 65-year-old farmer in Maguindanao, said that while the relief packs were welcome, what he and other farmers in the province really needed was to be able to plant again.

“Right now, I hope for the rain to come,” he said. Reports from Julie Alipala and Dennis Santos, Inquirer Mindanao
