Influence of Management Practices on Economic and Environmental Performance of Crops. A Case Study in Spanish Horticulture

This article assesses the effect of management practices on the environmental and economic performance of tigernut production. Tigernut is a horticultural crop grown in a very limited and homogeneous area. Results show that the environmental variability among farms was greater than variability in costs. A selection of practices can reduce impacts per kilogram tigernut by factors 252.5 (abiotic depletion), 33 (aquatic ecotoxicity), or 6 (global warming) and costs by factors of between 2 and 3. The analysis shows a positive relationship between economic and environmental performance. Results highlight how proper management leads to both relatively low environmental impacts and costs.
