Organic Farming
Organic farming is a production system that sustains the health of soils, ecosystems, and people. It relies on ecological processes, biodiversity, and cycles adapted to local conditions, rather than the use of synthetic inputs. Core principles include avoiding synthetic fertilizers, genetically modified organisms (GMOs), and industrial pesticides, favoring biological pest control and soil conservation techniques.
Principles & Methods
- Soil Health: Prioritizes compost, manure, and crop rotation to maintain organic matter and microbiome diversity.
- Biodiversity: Encourages polycultures and habitat preservation to support natural pest predators.
- Input Restrictions: Prohibits most synthetic agrochemicals; allows only approved natural substances under strict regulations (e.g., OMRI standards).
Challenges & Criticisms
- Yield Gaps: Often produces lower yields per hectare compared to conventional agriculture, raising concerns about food security scalability.
- Policy Implementation Risks: Sudden, top-down mandates for full organic transition without adequate infrastructure or gradual adaptation can lead to severe agricultural crises. A prominent example is the Sri Lanka’s Organic Fertilizer Policy Debacle: Motivations, Implementation, and Impact, where a 2021 nationwide ban on chemical fertilizer imports caused significant economic instability and crop failure.
- Economic Volatility: Transition periods often involve high costs for new inputs and labor-intensive practices before yield stability or premium pricing is achieved.
Case Study: Sri Lanka (2021)
- In April 2021, the government banned all chemical fertilizer imports to promote health and sustainability.
- The abrupt implementation lacked sufficient support systems, leading to plummeting yields in key export crops like tea and rubber.
- This event highlights the critical need for gradual transitions and robust safety nets when shifting from conventional to organic-farming models on a national scale.
