Determining the Environmental Effects of Bean and Lentil Production by Life Cycle Assessment Method) Case Study: Yasuj City(

Abstract

Abstract Background and Objective: The study was conducted to evaluate the environmental effects of the production process of two types of the most important legumes (beans and lentils) in Yasuj. Materials and Methods: The location of bean and lentil farms in Mokhtar village was 5 km from Yasuj city, which was studied in the 2016-2017 crop year. Necessary information was obtained through questionnaires, interviews with farmers, referring to the Agricultural Jihad in Yasuj and statistics of the Agricultural Jihad Organization. The life cycle assessment method was used to assess the environmental impact according to ISO 14040 standard. The study groups included global warming, acidification, land eutrophication, depletion of fossil resources, depletion of phosphate resources and depletion of water resources Results: The results showed that the value of the final index of all the affected groups (except for fossil fuel depletion) in the bean production process was higher than the value of lentil production indices and the final index of the effect of depletion of phosphate resources had the highest value among the affected groups. .The )ECO-X (Environmental Index for Bean 0.634 and for lentil 0.061 was calculated .also The Resource Drain Index (RDI) was also obtained for bean 1.14 and for lentils 0.661. Conclusion: fuel consumption and chemical inputs had significant effects on environmental pollution, which can be achieved by using low-tillage and non-tillage methods while saving energy and playing an important role in soil organic matter and improving its fertility.
