The Pejarakan project is located in proximity to the Bali Barat National Park, in Northwest Bali, which is recognized worldwide for it’s array of native biodiversity, both on land and in the sea. The project works towards regenerating, preserving and restoring this unique biodiversity.
Pejarakan is a village of farmers and fishermen heavily relying on the natural environment for their subsistence. However severe environmental degradation over the last decades has led to the loss of native biodiversity and economic instability. The villagers are determined to conserve and restore their marine, coastal and terrestrial ecosystems through community led initiatives aiming at promoting sustainable ecotourism in the area.
CORAL REEF RESTORATION
The coral reefs of Pejarakan were destroyed in the last 60 years due to destructive fishing practices such as dynamite and cyanide fishing leading to important losses of marine biodiversity. PUR Projet teamed up with the community group Pokmasta to restore the lost biodiversity through the construction of an artificial reef. The artificial structures provide a solid substratum for corals to grow on and will attract a wide range of other marine organisms. To support and sustain coral growth the project uses a technology called Biorock. Biorock consists in passing a low voltage current through the structures – the resulting electrolysis of seawater causes minerals that are naturally present in the seawater to precipitate onto the structures forming a solid limestone coating. Corals growing on Biroock structures are said to be more resilient to pollution and climate change.
PLASTIC WASTE MANAGEMENT
Indonesia is the second largest contributor of marine plastic after China; plastic pollution is threatening marine life and ecosystems causing an estimated 13 billion USD in damage every year. The project combines beach cleans with educational events, workshops and trainings, raising awareness for marine pollution as well as coral restoration and preservation. It also includes the implementation of metallic recycling bins and payable recycle collection for shops and businesses.
REFORESTATION & AGROFORESTRY
During the rainy season, heavy rains wash away large quantity of sediments, which are directly discharged into the sea. Sedimentation has a significant negative effect on coral health, hindering restoration effects by inducing additional stress on marine organisms. The project includes the planting of timber and fruit trees around fields, village temples and rivers beds in order to improve soil retention, reduce soil erosion and runoff, enhance water quality within the lagoon with direct positive impact on coral health, and provide an alternative income source for villagers (fruit and other tree by-product to be sold on local markets).
MANGROVE CONSERVATION & RESTORATION
The Pejarakan project aims also at conserving and restoring mangrove forests, very important for coral health, biodiversity and climate change adaptation (protect coastal areas against storms and floods). In partnership with the Forum Konservasi Putri Menjangan, PUR Projet establishes local mangrove nursery for plantation, restores disused salt farms to productive mangrove systems and pushes for legislative protection.
LocationPejarakan, Bali, Indonesia
Marine ecosystems conservation
Local partnerPokmasta, Putri Menjangan, University Dhyana Pura, Biorock Indonesia
Achievements8 artificial structures (+800 corals) ; 2,500 trees ; 25,000 magroves.
Coral reef restoration: Pokmasta, a community group of 63 members. Their aim is to develop eco-tourism activities based on Bali’s natural heritage whilst preserving the marine ecosystem. Additional partners of the artificial reef project are:
– Biorock Indonesia: a NGO focused on the implementation of the Biorock project. They bring technical expertise and external monitoring to the project.
– Yayasan Karang Lestari: a local NGO created after the installation of Bali’s first Biorock artificial reef in Pemuteran.
– The Dhyana Pura University: Some local and exchange students are leading a thesis research on artificial reeds and the effects of Biorock on the corals growth.
Mangrove replantation: Putri Menjangan, a community led initiative to conserve and regenerate the remaining mangrove forest in Pejarakan with a total of 143 members.
An umbrella organisation, run and managed by community leaders will take over the supervision of the different initiatives to increase the sphere of influence of individual groups and drive the shared conservation momentum in the area.
Coral reef restoration: Over 15 different coral species are planted on the artificial reef. The corals are collected in proximity to the project site and transported the short distance by boat. Only broken coral fragments are collected to avoid damage to the natural reef.
Mangrove replantation: 6 different species are grown in local nurseries before being planted in the field.
Agroforestry: farmers plant a minimum of 3 different species on their farms of a total of 8 species including guava, orange, maoni, gemelina and coconut.
Participants are members of the different community groups, their families as well as the wider community of Pejarakan. Trees for the agroforestry element are planted with local corn, peanuts and chilli subsistence farmers living in the area.
