Summary

n December 2024, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) approved the Nexus Assessment, which examined the interlinkages between biodiversity, water, food, health and climate change.

Nexus approaches are frameworks for analysing interconnections among sectors and systems to enhance synergies and reduce trade-offs. Based on these approaches, the assessment identified 71 response options that can address these interconnected issues and generate multiple benefits.

This session explored the relationship between nexus approaches and socio-ecological production landscapes and seascapes (SEPLS), such as satoyama and satoumi in Japan. The presentation highlighted how SEPLS can embody nexus principles and encompass many response options. Case studies from Ghana and India, supported by the Satoyama Development Mechanism, demonstrated practical applications. In Ghana’s Atewa Forest Reserve, ecosystem conservation and sustainable livelihoods were achieved through women’s cooperatives and agroforestry. In India’s Kalrayan Hills, the regeneration of sacred groves combined traditional knowledge and science to conserve endangered medicinal plants and local culture.

A panel discussion with IPBES authors emphasised that SEPLS-based practices—linking biodiversity, livelihoods and governance—closely align with nexus approaches and provide effective, grounded pathways for transformative sustainability.
