Philippines' green enforcers check the mangroves

FOR IMMEDIATE RELEASE

Restoring mangrove swamps is a valuable way of protecting coasts against storm damage. But it needs more than good intentions, as experience in the Philippines shows.

CATANDUANES, 7 June – Congresswoman Susan Yap, chair of the Philippines’ House of Representatives Reforestation Committee, is visiting Catanduanes, “the land of the howling winds”.  The island is the most easterly in a country of over 7,000 islands, the landfall for storms sweeping in from the Pacific, and therefore highly vulnerable.

“The Philippines is one of the most disaster-prone countries in the world”, says Yap. “We have several typhoons every year, but in the last five years we’ve seen an increase of about 30%. We are having 25 to 28 typhoons a year. Even their strength is much more, with winds of over 300 km per hour.”

Widespread deforestation has not helped. Over the 20th century national forest cover fell from 70% to 20%. It is currently declining at 2% annually. Without it topsoil is lost and flash floods increase in intensity.

The government’s response is its biggest environmental project, the National Greening Program. But there are concerns over its effectiveness, and Yap intends to find out more. “As a legislator it is my duty to make sure that government projects are implemented well”, she says.

Our TVE crew followed the committee from the House of Representatives to the mangroves of Catanduanes, crucial to protection against the typhoons. Mangroves are important not only to fisheries but to coasts and can reduce the impact of wave height by half over 100 m.

Think first

But at one of the Greening Program’s sites newly planted propogules (long single stems which the mangrove drops in order to reproduce) have been infested by barnacles. Considerable manpower has been used to clean the stems repeatedly but, as the committee points out, it would have been better spent planting in areas free from barnacles to begin with.

“Visiting the people in these places I have learnt that there is lack of funding for these projects and their implementation remains a challenge, so getting on the ground keeps our government people on their toes and makes them realise that hey, we are serious about this work”, Yap says.

Taking us round the mangrove sites, Captain Ivanhoe Arcilla, a former fighter pilot turned local disaster risk reduction and prevention officer, sums up his frustration: “Out of the 1bn pesos [US$23m] allocated for mangrove reforestation after typhoon Yolanda (Haiyan), some should have been allocated for research about mangroves.”

The centrepiece of the committee’s visit to Catanduanes was the public consultation meeting, a novelty in a country where people are unused to being consulted. It was an eye-opener, helping local congressman and fellow committee member Cesar Sarmiento draft legislation for later in the year.

Public voice

“The public consultation was the first in Catanduanes and some citizens shared their experiences”, he told us. “This is the information that’s needed by the committee, to fine tune and come up with legislation that can be effectively implemented.”

“This is the best thing, I mean this public hearing about mangroves and reforestation and all that, it’s the best thing that’s happened here in Catanduanes”, said Capt. Arcilla.

Legislators from 100 countries are meeting in Mexico for Globe International’s second World Summit of Legislators. Their immediate aim is to encourage countries to enact legislation to cut greenhouse gas emissions in the run-up to the comprehensive climate agreement which UN talks in Paris late in 2015 are intended to produce.

Yap says Catanduanes’ “bottom up” approach and the sharing of information chime with her membership of Globe: “I believe that Globe can assist a country like the Philippines in communicating within the international community to set up the framework for local legislators. Together we can find solutions and partnerships for having a low carbon green economy in the Philippines.”

And above all, when agreements are in place, oversight can ensure their effective operation: “Globe believes that legislators are accountable for the policies we’ve passed. Oversight and holding our executive and governments accountable for the work we’re doing is crucial.” – Climate News Network

Florida's mangroves head northwards

FOR IMMEDIATE RELEASE
Mangroves are colonising new areas in northern Florida, moving up the coast because the frequency of very frosty days is falling.

LONDON, 31 December – The mangroves of Florida are on the move. Mangrove forests in the north of the state have doubled in area in the last 28 years, thanks not to global warming as such, but because the number of sharply frosty days has dropped.

The discovery is in itself not a surprise – mangrove growth is limited by temperature – but once again it confirms a pattern of climate change and species migration in response to man-made global warming.

Kyle Cavanaugh and colleagues report in the Proceedings of the National Academy of Sciences that they examined 28 years of satellite imagery over one particular stretch of an important ecosystem on the coast of northern Florida between 1984 and 2011. All the increase occurred north of Palm Beach County, and growth in the area between Cape Canaveral National Seashore and St Augustine doubled.

“Before this work there had been some scattered anecdotal accounts and observations of mangroves appearing in areas where people had not seen them, but they were very local”, said Dr Cavanaugh, a researcher at the Smithsonian Institution in the US.

Simple pattern

“One unique aspect of this work is that we were able to use this incredible time series of large-scale satellite imagery to show that the expansion is a regional phenomenon. It’s a very large-scale change.”

The other important aspect of the research was that it eliminated some of the other possible causes behind the expansion of mangroves into the salt marshes a little to the north.

The pattern of change over the 28-year period, in which the area colonised by mangroves grew by another 1,240 hectares, was not a consequence of a shift in average temperatures, or of the change in management patterns, or an altered pattern of precipitation, or changes in the tidal regimes, or even altered rates of nutrient flow and sedimentation.

What emerged from the painstaking match of seasonal weather and mangrove advance was quite simple. With a decline in the number of days in the year in which a sharp frost occurred, and in which the temperatures fell to minus 4°C or below, the mangrove reach began to extend.

Salt marsh loses

It was not the overall warmth, but the change in the frequency of severe events that mattered most. And this change in frequency was surprisingly slight: just 1.4 fewer frosty days a year at Daytona Beach seemed to be enough to account for the expansion.

In the region overall, the scientists write, minimum temperatures have been rising faster than either the daily mean temperature, or the daily maximum. The implication is that stands of the mangrove genus Avicennia will go on colonising new habitat.

Mangroves are important ecosystems for both wildlife and for coastal citizens, and worldwide, mangrove forests have been under threat. But even a welcome change may not be entirely for the good.

“The expansion isn’t happening in a vacuum”, said Dr Cavanaugh. “The mangroves are expanding into and invading salt marsh, which also provides an important habitat for a variety of species.” – Climate News Network
