Life cycle management on Swiss fruit farms: Relating environmental and income indicators for apple-growing
چکیده انگلیسی

Integrated fruit production (IFP) has been practiced in Switzerland on a large scale basis since the late 1980s, with the aim of improving sustainable farming. The guidelines of IFP emphasise an ecosystem approach that is based on scientific knowledge about self-regulatory mechanisms at the tree and orchard level. Empirical studies at the farm level are rare. An understanding of the relationship between income and environmental impacts at the farm level is a prerequisite for devising a robust system for orchard portfolio management. An income analysis based on full cost principle and environmental life cycle assessment were applied to 445 annual data sets of apple orchards, recorded on 12 specialised fruit farms over a period of 4 years. The main result was that environmental impacts such as ecotoxicity, eutrophication and non-renewable energy use did not necessarily increase when farms increased their income. A higher input level of pesticides, fertilisers and machinery did not lead to increased yields and receipts. In contrast, the choice of apple cultivars and high investment in pre-harvest labour hours were significantly correlated with high eco-efficiency and high farm income. The results of this study were summarised in a pyramid-shaped management model, providing key issues of successful orchard farming and attributing management rules to master them. The management pyramid indicates that cognitive competences such as distributional, conditional and non-linear thinking are crucial when knowledge from tree and orchard management is integrated at the farm level. A main recommendation is that more attention should be paid to improving management competence in order to contribute to sustainable farming.
