Permaculture, a sustainable farming method, has the potential to integrate agriculture, environmental protection, and nature conservation. A recent study by the Technical University of Kaiserslautern-Landau (RPTU) and the University of Natural Resources and Life Sciences (BOKU) in Vienna underscores these benefits.

Originating in the 1970s as a response to conventional agriculture, permaculture emphasizes near-natural farming, excluding monocultures, pesticides, and heavy machinery. In Germany, this organic approach has been practiced for decades, incorporating trees and shrubs into fields and integrating livestock without using mineral fertilizers or pesticides.

Given climate change and biodiversity loss, sustainable farming like permaculture is increasingly crucial. This study marks the first analysis of permaculture’s environmental impact. “We wanted to investigate if permaculture truly offers the ecological benefits it promises,” said environmental scientist Julius Reiff from RPTU.

The research examined nine farms in Rhineland-Palatinate, Bavaria, North Rhine-Westphalia, Lower Saxony, and Luxembourg. Indicators such as soil quality and biodiversity were compared between permaculture and conventional farms. Soil samples assessed humus and carbon content, nutrients, and microorganism activity. Biodiversity was measured by the variety of earthworms, birds, and plants.

Findings revealed that permaculture areas had significantly higher soil quality and biodiversity. The carbon and humus levels matched those of grasslands, which have the highest humus content in Germany. These soils also exhibited better water and nutrient retention, aiding resilience to drought and suggesting higher nutrient content in crops. Biodiversity was notably enhanced, with permaculture areas showing three times more bird species, earthworms, and plants than conventional fields.

The study attributes higher biodiversity to the absence of pesticides and the mixed-crop cultivation common in permaculture. This approach often includes agroforestry, integrating trees and shrubs into farmland. “These improvements could represent a real trend reversal in the face of climate change and species extinction,” said ecosystem expert Martin Entling from RPTU.

Economically, permaculture proves viable, with yields comparable to industrial agriculture. For widespread adoption, the study suggests restructuring EU subsidies to favor sustainable farming and altering agricultural education.
