A historical analysis of the drivers of loss and degradation of Indonesia’s mangroves

Background

Indonesia is an important global hotspot for mangroves, with Indonesia containing over 20% of the world’smangroves. Low-lying mangrove areas are important for shrimp farming in Indonesia, both for local and international markets, which has led to mangrove deforestation and complex mangrove land-use governance. To develop more sustainable mangrove management strategies, it is important to assess Indonesia’s history of mangrove management to understand the main drivers of deforestation.

A Water Quality Evaluation of Integrated Mangrove Aquaculture System for Water Treatment in Super-Intensive White Leg Shrimp Pond

Background

White leg shrimp (Litopenaeus vannamei) farming is an integral part of Indonesia’s international market. Economic pressure to expand white leg shrimp aquaculture ponds leads to deforestation and degradation of mangroves. However, integrating shrimp aquaculture with mangroves can be a way to improve pond sustainability and environmental quality, especially in super-intensive aquaculture systems, which are highly controlled, technology-based aquaculture ponds that have high stocking densities to maximize shrimp yields.

Integrated mangrove-shrimp cultivation: Potential for blue carbon sequestration

Background

Mangrove deforestation and degradation have increased due to the growth of shrimp farming in tropical coastal environments. This has serious implications for global climate change mitigation, since mangroves are the most carbon-rich forests in the tropics, and converting mangroves into aquaculture ponds increases blue carbon emissions. Integrated mangrove-shrimp cultivation systems can help to prevent mangrove loss and curb blue carbon emissions through pairing shrimp aquaculture with mangrove restoration.

Effects of different management regimes on mangrove ecosystem services in Java, Indonesia

Background

Indonesia’s mangrove forests have decreased from 4.5 million hectares (ha) to under 3 million ha since the 1980s, largely due to the lack of monetary value attributed to mangrove ecosystem services, leading to conversion into aquaculture. Developing a valuation system for mangroves that includes both economically valuable products (i.e., timber, food) and ecosystem services allows decision makers to better assess the impacts of management decisions on the important ecosystem services and properties provided by mangroves.

Conservation for production? The benefits of mangroves for sustainable shrimp aquaculture

Background

Increasing shrimp demand and declining annual shrimp harvests threaten mangroves in East Kalimantan, Indonesia, due to deforestation from shrimp aquaculture expansion. Silvofishery practices that combine shrimp aquaculture with mangrove conservation are promoted to prevent further mangrove deforestation while still protecting the shrimp farming industry. Mangrove ecosystem services are essential for aquaculture systems to thrive, so it is important to determine successful biophysical elements of silvofishery systems to encourage the development of more sustainable aquaculture practices.

Valuing the Role of Mangroves in Storm Damage Reduction in Coastal Areas of Odisha

Background

Building resilience has become a significant concern for coastal communities due to future sea level rise and more frequent tropical storms caused by climate change. Mangroves can provide coastal resilience by reducing lives lost and property damage from tropical storms. These benefits demonstrate how including these ecosystem services in sustainable land use planning could be an economically viable coastal resilience strategy.

Mangroves protect coastal economic activity from hurricanes

Background

With more frequent and severe weather events anticipated due to climate change, coastal communities are interested in practical coastal defense interventions to protect their public and private assets and prevent disruptions to economic activity from tropical storms. Studies have documented mangrove forests’ ability to reduce wave action, wind velocity, and storm surge, making mangroves a cost-effective form of coastal protection. Yet, the relationship between how large a mangrove belt must be to provide significant protection and how mangroves mitigate tropical storm effects and economic damages is still unknown.

Participatory scenarios and spatial modelling to explore mangrove ecosystem services futures in Lamu, Kenya

Background

Lamu County, Kenya contains Kenya’s most extensive mangrove forests, which provide many vital ecosystem services (ES) for local communities (e.g., nutrition, building material, coastal protection, climate regulation). Land use and land cover change (LULCC), such as coastal development or infrastructure projects, threaten mangroves and their ES. Participatory scenario planning can help communities develop models of future LULCC grounded in both scientific evidence and local experience. Using these models in Lamu could inform future policy to preserve Lamu’s mangroves and balance country-level economic needs with local ES.

Life cycle impacts of forest management and wood utilization on carbon mitigation: knowns and unknowns

Background

Forests currently remove 2-3 GtC yr⁻¹ from the atmosphere, while global wood harvest exceeds 3-4 billion m³ yr⁻¹, creating complex interactions between forest carbon stocks, harvested wood products, and the substitution of wood for more emission-intensive materials. Lifecycle assessment (LCA) is widely used to evaluate these interactions, but differing system boundaries, baselines, and treatment of carbon pools can lead to very different conclusions about mitigation benefits. Clarifying where evidence is robust and where major uncertainties remain is essential for designing coherent forest-climate policy.
