Permaculture is proposed as a tool to design and manage agroecological systems in response to the pressing environmental challenges of soil degradation, climate change and biodiversity loss. However, scientific evidence on the effects of permaculture is still scarce. In this comprehensive study on a wide range of soil and biodiversity indicators, we examined nine farms utilizing permaculture and paired control fields with locally predominant agriculture in Central Europe. We found 27% higher soil carbon stocks on permaculture sites than on control fields, while soil bulk density was 20% lower and earthworm abundance was 201% higher. Moreover, concentrations of various soil macro- and micronutrients were higher on permaculture sites indicating better conditions for crop production. Species richness of vascular plants, earthworms and birds was 457%, 77% and 197% higher on permaculture sites, respectively. Our results suggest permaculture as effective tool for the redesign of farming systems towards environmental sustainability.

Expanding production in the ocean is expected to help address many challenges of the 21st century, from climate change to food insecurity. However, already declining ocean health and the legacy of socio-ecological harms from conventional agricultural practices on land suggest that a non-conventional approach to marine cultivation will be required. We explore marine permaculture as a possible system-design framework for future ocean stewardship that could lead to enhanced production alongside positive ecological and social outcomes. On land, permaculture has taken root as a framework for designing socio-ecological systems that seek to be productive, resilient, and equitable in the long term. Here, we imagine how permaculture’s design principles and ethics might manifest in the ocean and describe how it dovetails with recent scientific advances in ocean technologies and governance. Further developing and implementing marine permaculture could enable the realization of productive seascapes that avoid undermining progress toward sustainable development.
