Coastal Communities and Culinary Traditions: Mangrove Restoration in Pati

The uniqueness of bandeng presto (steamed milkfish) lies in its cooking technique. Steaming the fish at high pressure creates a delicate texture that locks in flavor and allows the meat to fall effortlessly off the bone. After being cooked in this way, even the soft spines of the fish can be eaten. From beachside pots to the kitchens of restaurants, local cooks have mastered this technique, and milkfish have become a dish that’s synonymous with Pati Regency of Central Java. 

This iconic fish puts food on the table in more ways than one. Many people living in Pati make their living as fishpond farmers, with milkfish being their main source of income. However, these industries are increasingly under threat from flooding. Now, with the help of Trees4Trees, farmers are finding that mangroves have the power to reverse the damage and protect their livelihoods. 

An Essential Resource for Local People 

In a year, fishpond farmers in Pati can harvest milkfish two or three times, depending on the weather. “We can sell one kilogram of milkfish for around 15,000 to 25,000 rupiah (US$ 1 to 1.60),” explains Djamari, one of the fishpond farmers from Dukuhseti village. He only cultivates milkfish, as this is the most reliable, most profitable commodity.  

Parmi, another fishpond farmer from Dukuhseti village, agrees. As he explains, “milkfish is the main component of authentic foods in Pati, so the demand is always high,” he added.

Livelihoods Under Threat: Extreme Weather and High Waves  

Fishponds in Pati are increasingly under threat. Recently, when the tide is high, and the weather is bad, the surge can flood the fishponds and decimate stocks of the precious milkfish.  

“Virtually every year, our fishponds are threatened by waves,” explains Parmi. “Last year, when my pond was destroyed, only a few fish were left. I suffered losses of nearly 100 million rupiah due to the damage,” he revealed.  

Parmi’s story is familiar to many fishpond farmers in the region. Djamari added that he has experienced similar problems, which were disastrous to his business. “I estimate that my losses due to last year’s high tide were in the tens of million rupiah,” he said.  

However, Djamari and Parmi actually fared much better compared to their neighbors in other villages. This is because their ponds were protected by mangroves. “Even though there are not many, these mangroves protected our fishponds,” explained Parmi, pointing to the mangrove trees around him.

The Many Benefits of Mangroves 

Musthofa is the leader of a group of fishpond farmers in Dukuhseti village. He laments that mangrove cover in Pati has been in decline in recent years. “Everything within a hundred meters of the shoreline should be a greenbelt area,” he explains, noting that this protection is largely absent. “Most farmers in our group are aware of the benefits offered by mangroves; we have seen ponds protected with mangroves suffer less damage than areas that are not,” he added.  

“The mangrove trees around our pond were planted in 1995 and stand up to 10 meters tall,” explains Parmi, who also revealed that these trees can offer multiple benefits to farmers. “They not only prevent erosion and waves – the fallen leaves also function as natural fertilizers to fishponds, which accelerates fish growth,” he said.

Restoring Coastal Areas, Supporting Farmers, and Preserving Traditions 

Djamari, Parmi and Musthofa are three of the many local farmers who have been helping Trees4Trees to restore coastal ecosystems and protect livelihoods in Pati. Since 2021, we’ve planted around 138,000 mangrove trees in an area covering 27.8 hectares; in the most recent planting season alone, we planted mangroves in eight coastal villages.  

“We hope the mangroves we have planted will grow tall and strong so they can protect fishponds and prevent coastal erosion in areas around our village,” said Parmi. He added that by planting mangroves, the authentic culinary traditions of Pati – such as bandeng presto – will also be preserved.

Mangroves have enormous benefits for the environment and the economy. From preventing coastal erosion, storing a large amount of carbon and fighting climate change, providing a home and nursery ground for a wide range of animals, to providing multi-benefit for human life.   

Indonesia is home to one of the largest mangrove populations in the world with around 3.2 million hectares of mangrove covers. In this archipelago country, there are five mangrove types (genera) and around 202 species that are commonly found in coastal areas. Each type of mangrove has its own characteristic, and the most important thing is, they have amazing benefits. 

Let’s find out what types of mangroves can be found around Indonesia’s coastal areas and what are their benefits!

Rhizophora Mangrove

In Indonesia, Rhizophora is also known as bakau and it has three species; Rhizopora apiculata, Rhizophora mucronata, and Rhizophora stylosa.  Rhizophora has taproots that plunge into the forest floor. This type of root is growing above the surface of the soil. These roots stick out from the tree trunks and extended outwards.  

Rhizopora mucronata’s leaf, bark, and propagule waste can produce a natural brown dye to color fabrics and is one of the natural dyes for batik (Indonesian traditional fabrics). The young leaf is also beneficial as a mouth antiseptic. Ecologically, Rhizophora is effective to protect coastal areas from erosion. It is commonly planted along the shore and the edge of the fishponds to protect it from big waves.  

Avicennia Mangroves 

Avicennia is popular in Indonesia with its local name, api-api. Avicennia has pencil-shaped roots. They are embedded in the forest floor, protruding from the surface of the water, and scattered in very large numbers around the tree trunk. These roots serve as breath roots.

It has five species; Avicennia alba, Avicennia eucalyptifolia, Avicennia lanata, Avicennia marina, and Avicennia officinalis. Even though, Avicennia marina is the most species found in Indonesia.  

Almost all parts of Avicennia are beneficial, from its roots, barks, tree trunks, stems, leaves, and flowers to its seeds. The fruits contain a high level of protein and various vitamins, like B and C, and can be processed into various foods which can increase the coastal community’s income by selling them. The leaves are used as fodder as well as a traditional medicine to treat skin burns and other skin diseases due to their anti-bacterial content. The strong tree trunks are often utilized as boat frames.  

Besides its ability to prevent coastal erosion and store carbon, based on research, Avicennia has a special ability to reduce metal toxic materials in mangrove forests through a dilution process.

Bruguiera Mangrove 

Bruguiera has the most species compared to other mangrove types. It has six mangrove species; Bruguiera cylindryca, Bruguiera exaristata, Bruguiera gymnorrhiza, Bruguiera haenessii,  Bruguiera parviflora, and Bruguiera sexangula. Generally, it has pointed-shaped leaves with strong stems and thick roots which look like bent knees as its characteristic.

Like other mangrove, Bruguiera has numerous benefits. Besides preventing coastal erosion and storing carbon, most parts of Bruguiera trees are beneficial. Bruguiera gymnorrhiza young leaves can be processed into food. The barks are often used as a traditional medicine to treat diarrhea, fever, and skin burns, and are believed to prevent malaria. Bruguiera sexangular has a high economic value. Its fruit can be processed into herbal drinks too. 

Ceriops Mangrove

Ceriops mangrove is also known as tengar tree in Indonesia. It has pencil-shaped roots, elongated fruits, and bubbling stems as its characteristics. The appearance of Ceriops is like Rhizophora but smaller. It is usually found in dry parts of Rhizophora mangrove forests. The tree bark produces tannin which is beneficial as a natural dye to produce a yellow color. Ceriops has two species that exist in Indonesia; Ceriops decandra and Ceriops tagal

Sonneratia Mangroves

Sonneratia has a pencil-shaped root system, and its appearance looks like Avicennia, but they have a different shape of flower, fruit, and leaf. There are three species of Sonneratia in Indonesia; Sonneratia alba, Sonneratia caseolaris, and Sonneratia ovata. Sonneratia caseolaris’s fruit contains a high level of Vitamin C. It also contains Vitamin B1, B2, and antioxydant. Sonneratia tree trunks are often used as a raw material for firewood and charcoal.

Mangroves accommodate incredible benefits and impacts for nature and human beings. Unfortunately, mangroves have experienced loss and degradation worldwide. As part of the contribution to restore mangrove covers, Trees4Trees started planting 36.000 mangroves in 2021 on the coast of Dukuhseti Village in Pati regency, Central Java. It aimed to prevent coastal erosion and protect fishponds owned by local farmers.  

This planting season, Trees4Trees expands the mangrove planting to five villages in Pati regency and in Cilacap regency, Central Java. The main aim of planting mangroves is to prevent coastal erosion and restore the original mangrove forests. By broadening the mangrove planting area, it is expected to contribute to the mangrove ecosystem restoration in Indonesia.
