AHP ANALYSIS FOR MICROZONING OF VINEYARDS BY GIS

Abstract

The Analytic Hierarchy Process (AHP) is a widespread mathematical technique for multi-criteria decision-making analyses, deals with the structured hierarchical database models, gathered from interdisciplinary criteria for future perspective analyses in the specific sector. Viticulture microzoning and terrain selection for potential vineyards are becoming important knowledge for vine farming systems. In this study the AHP method is used to gather, structure and resolve the data of variety sorts of vine, evaluate the physical natural resources (climate, soil and relief), socioeconomic and infrastructures conditions to dissolve different environmental problems of vineyards management. GIS (Geographical Information Systems) tools allow making multi-criteria analysis and combined various data of vineyards for digital complex environmental assessment. The site selecting for a new vineyard for wine-grape or wine production is a fundamental and crucial decision as several factors have influenced on it.
