Introduction/Context
Overview:
“A Manual on How to Sustainably Manage Sea Grapes in Western Province, Solomon Islands” was developed by WWF-Pacific Solomon Islands to support coastal communities in sustainably managing sea grape resources while strengthening livelihoods, food security, marine conservation, and climate resilience.
Background:
Sea Grapes are an important food and income source for coastal communities in Western Province, particularly for women harvesters. Communities including Sairagi, Boboe, Pusiju, and Kongulavata rely heavily on sea grape harvesting and sales for household incone, school fees, and food security. However, overharvesting, mangrove cutting, reef degradation, sedimentation, and climate variability have negatively impacted sea grape abundance and ecosystem health.
Problem statement:
Declining sea grape abundance threathened marine ecosystems, food security, women’s livelihoods and long-term resilience. Communities required practical guidance on sustainable harvesting, ecosystem protection, monitoring, climate adaptation, and value-added livelihood development.

Specific location
Western Province, Solomon Islands including Sairagi, Boboe, Kongulavata, and Pusiju communities
Geographical detail
Coastal reef and mangrove ecosystems where sea grapes naturally grow.
Scale
Approximately 406 hectares of marine ecosystem under improved management.

Structure:
To advance sea grape conservation, initiatives first built robust community awareness, introducing local populations to the ecological, nutritional, and livelihood importance of sea grapes, mangroves, and healthy marine ecosystems. This foundation enabled stakeholders to establish community management structures by forming Management Committees, nominating Community Facilitators, and appointing Community Rangers. Working together, they developed community-based management plans with shared visions, clear zoning, and customized harvesting rules.

Central to these plans was the implementation of sustainable harvesting practices; women harvesters adopted precise pruning techniques—harvesting only shoots instead of uprooting whole plants—to allow faster regrowth. To prevent overexploitation, communities introduced harvesting limits and closure systems, enforcing basket limits and temporary closures. Simultaneously, they strengthened ecosystem protection measures by restricting mangrove cutting, pollution, and reef damage. To track progress, Community Rangers conducted regular biological and community monitoring using transects and quadrats to guide management decisions.

On the economic side, communities improved post-harvest handling and market systems, refining cleaning, packaging, and transport to maximize freshness and market value. This commercial optimization promoted women-led livelihoods and savings systems, boosting household income while fostering long-term financial security through savings clubs. Finally, communities developed value-added sea grape products like soaps and lotions, effectively diversifying local livelihoods and reducing harvesting pressure during critical closure periods.
Actions Taken:
Developed community-based sea grape management plans
Established SOmmunity Ranger monitoring systems
Introduced sustainable harvesting and pruning practices
Conducted ecosystem monitoring
Implemented harvest closures and harvesting limits
Developed sea grape soap and lotion products
Supported women-led savings and livelihood initiatives
Materials/inputs:
WWf-Pacific sea grape management manual
Monitoring tools and GPS
Traditional harvesting baskets (telas)
Community workshops and training
Monitoring and ranger systems
Success factors:
Strong community ownership
Integration of traditional knowledge and scientific monitoring
Women-led livelihood systems
Clear management rules
Community Ranger monitoring systems

Critical challenges:
Avoid uprooting entire sea grape plants
Use temporary harvest closures when needed
Combine traditional knowledge with scientific monitoring
Strengthen women’s leadership

The Breakthrough:
Communities combined traditional ecological knowledge with scientific monitoring and adaptive management approaches

Success factors:
Strong women-led participation
Community ownership
Adaptive management using monitoring data
Integration of conservation and livelihoods

Result snapshots:
Sea grape abundance improved, women’s livelihoods strengthened, and communities developed new value-added products.

Transferable tips:
Avoid uprooting entire sea grape plants
Use temporary harvest closures when needed
Combine traditional knowledge with scientific monitoring
Strengthen women’s leadership
