Sustainability analysis of apple orchards: Integrating environmental and economic perspectives

Abstract

The agricultural sector faces numerous challenges today, including the protection of biodiversity and the mitigation of environmental impact. Addressing these challenges require ensuring the stability of farmers' income, thus facilitating effective land management. The present study aims to evaluate the environmental and economic sustainability of apple orchards under two distinct systems (integrated versus organic) and a scab-resistant variety. The Life Cycle Assessment method (LCA) was employed to evaluate environmental impact, while financial and economic aspects were analysed using metrics such as Net Present Value (NPV), Equivalent Annual Value (EAV), Benefit-Cost Ratio (B/C) and Discounted Payback Period (DPP). Results analysis reveals that both inorganic fertilisation and pesticides usage have the greatest impacts in both integrated cultivation and scab-resistant orchards. In organic orchards, diesel usage emerges as a primary factor due to the substitution of chemical interventions with mechanical methods. For the same reason, labour constitutes 45 % of the organic production costs. Despite the lower environmental impact, organic treatments still contribute 22 % of the total production cost. Regarding the investment evaluation, the scab-resistant variety offers marginally lower costs than conventional varieties due to the reduction of required treatments; however, organic farming shows superior economic performance despite higher production costs, mainly attributed to higher market prices. This highlights the influence of market dynamics on business decisions in the apple sector, where farmers often have no direct control.
