Silvo-fishery & Carbon
Oleh Nyoman N. Suryadiputra
(Wetlands International Indonesia Programme)
What is silvo-fishery ?Can silvo-fishery practices gain carbon How is the results ? Any lessons can be learned ?How Aquaculture Certification related to mangroves ?
What is sylvo-fishery ??a fish/shrimp pond combined with mangrove trees- a
constructed wetland How many percent of pond area covered by trees ??What is the trees’ density ?? 2000 – 20,000 trees /haWhere the trees should be planted (type of sylvo-fishery pond) ?Why sylvo-fishery ? And what are the benefits ?
prevent soil slides from dykes (water quality control), biodiversity, shade, organic fertilizer, support green belt, climate mitigation & adaptation etc.
• 385 existing certification systems, incl. FT, organic, eco- , etc.• In aquaculture there are 27 (..we have identified so far)• Two of these were selected in our study :
1. Global GAP: non-Multi Stakeholder, third party (assessor), no label, food safety oriented
2. Aquaculture Stewardship Council: Multi Stakeholder, third party (assessor), label, environment and social impact oriented
Mangrove Relevancy to ASC – Global GAP.

Mandatory green belt (Presidential Decree no 32 year 1990). Total 70 ha, existing forest < 2 ha, 70 ha need to be (manually) rehabilitated by planting mangrove
Mandatory riparian (Ministry of Public Works Decree no 63, year 1993 ). Total 270 ha, existing forest cover 105 ha around 165 ha need to be (manually) rehabilitated.
Existing forested area inside farms, around 75 ha
ASC Principles:2.2 Protected Area and Critical Habitat2.4 Ecological Buffer, Barrier, and Corridors.
Global GAP Principles:5.8 Pond Management: vegetative buffer and habitat corridor10.4 High conservation value area: sitting of farm and mangrove reforestation
