Abstract: (206 Views)
The agricultural ecosystem provides various functions and services for humans. So, investigating their role and importance in the agricultural land programming and management is one of the goals research. In this research used Common International Classification of Ecosystem Services (CICES) for the identification of the Agricultural Ecosystem Functions and Services (AEFS). Also, Multi-Criteria Decision-Making (MCDM) models used for weighting and prioritizing of the AEFS like Step wise Weight Assessment Ratio Analysis (SWARA) for calculating of their weight, and Simple Additive Weighting (SAW), Additive Ratio Assessment (ARAS), and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) used for prioritization them. The research data extracted with field survey, random sampling and completing the Delphi questionnaire of the 40 agricultural specialist experts in the north of Iran. Also, the R2 coefficient was used to compare the AEFS prioritization models. The SWARA technique findings showed that provisioning, regulation, and cultural functions with weights of 0.0298, 0.0286 and 0.0250 have the highest weight, respectively. Also, the results indicated that the SAW model with the R2=0.90 was chosen as the prioritization appropriate model. Provisioning, regulation, and cultural functions with marginal weights of 0.6319, 0.5448, and 0.5092 were ranked the first to third priority respectively. Also, food supply, employment, genetic material supply, and educational and research services were important positive services of the agricultural ecosystem compared to other services. it is suggested that more appropriate programming and more research be done by relevant organizations for the sustainable management of agricultural ecosystems in northern Iran.
