The Possible Advantages and Difficulties of Mangrove Restoration in Indonesia for Sustainable Development of Climate Change

While mangrove restoration projects in the past have shown success rates of up to 85% globally, they have usually only covered smaller areas, ranging from 10 to 400 hectares. The expenses of these projects have varied from $1,500 to $9,000 per acre. Planning is crucial since Indonesia aims to restore 200,000 hectares of mangroves, which is a significant area.

This enormous project is expected to cost between $290 million and $1.74 billion. The government has allocated around $100 million per year in the 2021 budget for mangrove rehabilitation through the BRGM (Badan Restorasi Gambut dan Mangrove); nevertheless, this amount is far less than the expected total cost. Nonetheless, scalable mangrove restoration success in Indonesia might be possible with more foreign funding.

In Indonesia, efforts to restore mangroves have focused on a large number of unproductive aquaculture ponds. However, as shown by the low survival rates of planted seedlings, these attempts frequently encounter difficulties. This emphasizes the necessity of creative methods for mangrove rehabilitation and potent evaluation techniques.
