Protect and restore mangrove forests

Introduction

Mangrove forests play a vital role in coastal areas, particularly from an ecological perspective, as they are able to store large amounts of carbon through a sequence process and inhibit climate change by absorbing CO2 from the atmosphere. However, in recent years, there has been a change in land cover due to the conversion and degradation of mangrove forests, which causes the release of carbon and imbalances in the soil structure, causing CO2 flux to the atmosphere. This study was conducted at the Gading and Langkat Northeast (KGLTLWR) Karang Wildlife Reserve in North Sumatra, Indonesia, with a focus on six different types of land cover: natural forests, restoration, mixed agriculture, rice fields, oil palm plantations, and ponds.

Background

Mangrove forests are one of the most valuable ecosystems on the planet, providing a range of ecosystem services, including shoreline protection, water filtration, and carbon sequestration. However, mangrove forests are under threat from deforestation, land conversion, and climate change, which can lead to the loss of carbon reserves and increased CO2 flux to the atmosphere. The conversion of mangrove forests to other land uses, such as agriculture and urban development, can result in the release of stored carbon and the degradation of soil quality.

Methodology

The main purpose of this study is to measure the total carbon reserves in mangrove forests that have been converted to other types of land cover and estimate the level of CO2 flux in the area. The methods used include sampling in three transects and six plots for each land cover. To calculate tree biomass, the non-destructive method is applied by recording each stem diameter above 5 cm, while measuring soil carbon, drilling is divided into five depths at each plot. CO2 flux is measured using the CO2 Eosense Eosgp sensor with a static closed space method.

Results

The results showed that the highest carbon reserves were found in natural forests with a value of 308.09 mg ha-1, while the lowest reserve, 3.22 mg ha-1, was in mixed agriculture. In terms of soil carbon, the highest value is recorded in natural forests with 423.59 mgc ha-1, while the lowest value, 50.44 mgc ha-1, found in dry mixed agricultural land. The highest average CO2 flux value, 1362.24 mgco2 m2 H-1, is measured in the mangrove restoration area, while the lowest value, 123.03 mgco2 m2 H-1, occurs in the pond.

Discussion

The findings of this study provide a valuable picture of how much carbon reserves are lost when mangrove forests are converted to other land uses. This data is very useful as a reference for policy makers in providing mangrove forest management in the future, as well as developing mitigation steps to reduce carbon emissions. Given the importance of mangrove forests in storing carbon and its role in climate change mitigation, efforts to protect and restore this ecosystem are crucial.

Conclusion

This study highlights the importance of mangrove forests in storing carbon and mitigating climate change. The results of this study provide valuable information for policy makers and conservation efforts to protect and restore mangrove forests. Further research and policy implementation based on the results of this study can contribute to environmental sustainability and reduce the impact of climate change.

Recommendations

Based on the findings of this study, the following recommendations are made:

Protect and restore mangrove forests: Efforts should be made to protect and restore mangrove forests, particularly in areas where they have been degraded or converted to other land uses.
Develop sustainable land use practices: Sustainable land use practices, such as agroforestry and permaculture, should be developed and implemented to reduce the impact of land conversion on mangrove forests.
Implement climate change mitigation strategies: Climate change mitigation strategies, such as reforestation and afforestation, should be implemented to reduce carbon emissions and mitigate the impacts of climate change.

Future Research Directions

Future research directions include:

Long-term monitoring of mangrove forest carbon reserves: Long-term monitoring of mangrove forest carbon reserves should be conducted to track changes in carbon storage over time.
Assessment of the impacts of climate change on mangrove forests: Assessment of the impacts of climate change on mangrove forests should be conducted to understand the potential effects of climate change on mangrove forest ecosystems.
Development of sustainable land use practices: Development of sustainable land use practices, such as agroforestry and permaculture, should be conducted to reduce the impact of land conversion on mangrove forests.
