In several regions of Indonesia, particularly in Sumatra, there exists a local wisdom that plays an important role in preserving nature, especially biodiversity. It is known as Lubuk Larangan, a traditional community system that regulates the use of aquatic resources by imposing a temporary ban on fishing and harvesting other aquatic species within a designated area. This prohibition is supported by agreed sanctions for any violations. At the start of the Lubuk Larangan period, the community releases fish fingerlings into the river. When the period ends an event often referred to as the grand harvest villagers collectively catch fish from the area.
Agincourt Resources recognises that the Lubuk Larangan tradition plays a crucial role in maintaining biodiversity and preventing overexploitation that could threaten the survival of certain fish species. Therefore, the Martabe Gold Mine supports the implementation of this local conservation practice.
Since 2022, Agincourt Resources has actively promoted the establishment of Lubuk Larangan areas across several villages surrounding the mining site, releasing tens of thousands of fish fingerlings. To date, seven Lubuk Larangan zones have been developed in the Batang Toru Sub-district, namely Garoga, Batuhoring, Aek Ngadol, Sumuran, Sipenggeng, Batu Hula, and Hapesong Lama. In 2025, Agincourt Resources expanded the initiative to Padang Lancat Village and Pesong Plantation, releasing a variety of fish species such as tilapia, carp, gourami, and the rare jurung fish.
In May 2025, the Lubuk Larangan in Garoga River was opened to the community, resulting in a collective harvest of 250 kilograms of jurung and carp.
Beyond protecting aquatic ecosystems, Lubuk Larangan also serves to raise community awareness about the importance of environmental conservation. Furthermore, its implementation represents one of Agincourt Resources’ tangible community empowerment programmes, carried out in collaboration with residents.
In Garoga Village, for instance, a public fishing area has been established, where proceeds from ticket sales are used to fund social initiatives such as aid for orphans and the elderly, the purchase of a village ambulance, and other community-based programmes. Plans are also underway to develop the area into a water and culinary tourism destination.
Agincourt Resources’ initiative to engage communities in the management of Lubuk Larangan reflects a long-term commitment to safeguarding ecosystem health an essential element in maintaining ecological balance and mitigating climate change. It is hoped that this initiative will continue to deliver sustainable positive impacts for the environment, local communities, and the regional economy.
