Biodiversity Toolkit

This Biodiversity Toolkit provides standardised field protocols to assess key ecosystem processes, including soil fauna activity, decomposition and nutrient cycling, pest pressure, pollination success and seed predation. The toolkit strengthens capacity for participatory biodiversity assessment, enabling practitioners and communities to generate comparable data to inform sustainable land management and Nature-based Solutions.

State of the World’s Seaweeds 2025

 

The State of the World’s Seaweeds 2025 presents a global assessment of seaweed biodiversity, production, trade and sustainability, synthesising ecological and socio-economic evidence to inform conservation and responsible industry growth.

It highlights trends in wild harvesting and aquaculture, pressures on coastal ecosystems, governance gaps, and opportunities to strengthen sustainable management and equitable value chains. The analysis supports improved data systems, policy coherence and investment in climate-resilient seaweed sectors.

Socio-economic Baseline report (Lake Tseny)

This case study presents evidence from the Following the Water project which researches drivers of wetland degradation at Lake Tseny, Madagascar. The study traces water quality and quantity through social, ecological and biophysical elements to build a holistic understanding of wetland systems and co-produce Nature-based Solutions with local communities. Findings identify key pressures on wetlands, inform sustainable resource management and strengthen links between biodiversity, climate resilience and livelihoods.

Global seaweed stock and Marine Protected Area assessments provide potential opportunities to protect wild seaweeds

This Applied Phycology article presents findings from the GlobalSeaweed SUPERSTAR project assessing seaweed aquaculture and wild harvesting in relation to biodiversity protection and Marine Protected Areas. Using global mapping and multi-dataset analysis across 82 countries, the study identifies 261 commercially used species, highlights major gaps in species identification and production reporting, and shows that nearly half of seaweed activities occur within 1 km of MPAs. With relevance to Indonesia and Malaysia, findings inform strategies to protect wild stocks, strengthen coastal ecosystems, build capacity and improve livelihoods.
