Rising seawater levels threaten livelihoods and homes in Indonesia's Java

The fishing community's battle against inundation, blamed on both man-made environmental destruction and the impact of climate change, reflects the risks posed to millions of people by a sinking coastline on Indonesia's most populous island of Java.

Dwindling catches for fishermen

Indonesian fisherman Miskan says the once-abundant catches he used to enjoy have been dwindling in recent years on this stretch of the Java Sea.

His meagre income is being further strained by having to borrow cash to shore up his home against lapping waves coming further inland on this vulnerable coastline.

"If you have a house on land and then work at sea, it's hard. But now I work at sea and I live at sea," said Miskan, 44, who uses one name, speaking outside his small home, where a caged songbird hangs from the rafters.

Major flooding underway

The flooding in Tambaklorok in Central Java province is now so bad that Miskan uses a window to enter his home since his door is half blocked by dirt piled up to keep out the sea. "It's hard to save money when you're a fisherman," he said. Miskan had to borrow from neighbours to pay roughly 7.2 million rupiah ($500) to hire workers to truck in earth.

Global uproar over climate change

Thousands of people in Asia and Europe joined rallies demanding more action on climate change on Friday, aiming to force political leaders to come up with urgent solutions at a United Nations conference that starts on Monday.

Indonesia peculiarly vulnerable to climate change

Indonesia, an archipelago of thousands of islands, has about 81,000 km of coastline, making it particularly vulnerable to climate change along with neighbours like the Philippines.

Decimation of mangroves add to woes

Indonesia is also home to more than a fifth of the world's mangrove forests, which naturally help keep out high tidal waters. But for years, coastal communities have chopped down mangrove forests to clear the way for fish and shrimp farms, and for rice paddies.

The government has scrambled to work with environmental groups to replant mangroves, build dykes and relocate threatened villages.

Plan in action

Feri Prihantoro of the Bina Karta Lestari Foundation, a non-government organisation (NGO) focused on sustainable development, said the area's coastline was particularly vulnerable to flooding and high tides due to land subsidence because of the extraction of underground water and higher sea levels.

Further along the Java coast, Jakarta is also prone to flooding with two-fifths of the city lying below sea level.

With this partly in mind, President Joko Widodo announced in August a $33 billion plan to move the capital to Borneo island.
