Transforming Nickel Mines in the Philippines into Sustainable Operations

In a bid to restore damaged landscapes, the Philippines government has launched the Greening Mined-out Areas programme, aiming to complete the rehabilitation of 21 identified mined-out areas by 2033 via bioremediation. This initiative, focusing on the use of soil micro-organisms, could potentially work in any site, irrespective of the heavy metals present.

The Philippines, the world's second-largest producer of nickel, has approximately 700,000 hectares of land covered by mining tenements. Across the country, 9 million hectares of land have high mineral potential, making it a hotspot for mining activities. However, these activities often lead to biodiversity loss, soil degradation, pollution, and destruction of water systems.

To address these issues, researchers are turning to bioremediation, a process that uses micro-organisms to break down contaminants in soil and water. In the Philippines, this method is being used to help rehabilitate mined areas, with the potential to restore soil health and promote natural vegetation growth.

The government's ongoing reforms in mine regulations aim to increase transparency and accountability, including the proposed use of blockchain technology to monitor state expenditures. However, specific updated details on mining laws or regulatory changes were not found in the provided search results.

Despite the challenges posed by intense rainfall and frequent typhoons in tropical countries like the Philippines, which can flood contaminated sites, affecting the microbes' ability to work, researchers remain optimistic about the potential of bioremediation. Soil takes approximately a decade to restore after deforestation, and a forest takes 25 years to get back to normal.

The Thomson Reuters Foundation, focusing on humanitarian news, climate change, resilience, women's rights, trafficking, and property rights, has published a story on this topic. The story is related to topics such as carbon & climate, cities, energy, policy & finance, waste, and water.

It's important to note that the method of using soil micro-organisms for rehabilitation is not limited to solving problems caused by planting trees alone. The approach can potentially address a wide range of environmental issues, offering a promising solution for the restoration of mined-out areas in the Philippines and beyond.

Moreover, Philippine laws require mining companies to restore closed or depleted mining areas. While at least 27 abandoned and inactive mines remain unrehabilitated, the Greening Mined-out Areas programme represents a significant step towards addressing this issue.

As the world grapples with the impacts of climate change and the need for sustainable development, initiatives like the Greening Mined-out Areas programme in the Philippines offer a glimmer of hope for the future of our planet. By harnessing the power of nature and innovation, we can work towards a more sustainable and resilient world.
