Agroecology
A farming approach that applies the principles of ecology to food production, aiming for sustainable, resilient systems that respect soil, biodiversity and the climate.
Agroecology is at once a science, a set of practices and a movement. It treats farming as an ecosystem to be optimised as a whole, rather than maximising a single yield through chemical inputs. It aims for long-term sustainability.
Caring for the soil, the forgotten foundation: a little-known central principle, as agroecology puts soil health at the heart of everything. A living soil (rich in micro-organisms, worms and organic matter) is the foundation of nutritious food and resilient farming.
A direct link with nutrition: depleted soils (intensive farming, monocultures, excessive ploughing) produce food that may be lower in minerals. Studies suggest a fall in the mineral density of some fruit and vegetables over recent decades, partly linked to soil depletion (and to the selection of high-yield varieties). Agroecology, by regenerating soils, aims to reverse this trend.
Agroecological practices:
- Crop rotation and diversity (versus monoculture), giving richer soils and fewer pests
- Soil cover (no bare soil), protecting against erosion and supporting microbial life
- Reduced ploughing, preserving soil structure and life
- Companion cropping (e.g. the “three sisters” of maize, beans and squash) and agroforestry (trees plus crops)
- Biological pest control (natural predators versus pesticides)
- Compost and organic matter (versus synthetic fertilisers)
- Preserving biodiversity (hedgerows, pollinators)
The difference from organic: agroecology and organic farming overlap but are not identical. Organic is a regulated set of standards (a label, a ban on synthetic inputs). Agroecology is a broader systems approach (which can go beyond organic, or be applied partly in conventional farming). You can be organic without being fully agroecological (intensive organic monoculture), and vice versa.
Issues and debates:
- Yields: sometimes lower in the short term, but more resilient and sustainable in the long term (less dependent on inputs, better able to cope with climate shocks)
- Feeding the planet: debate over the ability to feed 8 billion or more people, while supporters point to reduced waste and systemic efficiency
- Transition: requires support for farmers
In practice (for the consumer): supporting agroecology means choosing products from these practices (often via short supply chains, committed farms, some labels), reducing waste, and eating a more plant-based and varied diet. It is a pillar of a sustainable diet.
