Abstract
This study aims to identify and analyze the key factors influencing water productivity in agriculture through the application of the Fuzzy Delphi Method.Through a systematic literature review, 194 factors were extracted and categorized into three domains: climate change (43 factors, 22.1 Percent), policy (77 factors, 39.6 Percent), and technology (74 factors, 38.2 Percent). These factors were incorporated into a semi-structured questionnaire distributed to 18 experts. Applying a consensus threshold of 0.8 in the fuzzy Delphi model, the data were fuzzified, aggregated, and defuzzified. Findings revealed that 32 factors (16.5 Percent) were selected as consensus-based key determinants. Among them, 18 factors were from the policy domain (23.4 Percent), 10 from the technology domain (13.5 Percent), and 4 from the climate change domain (9.3 Percent). The highest defuzzified value corresponded to "hybrid seed production" (0.92), highlighting the significance of biotechnological innovations in enhancing water productivity. Other consensus-driven factors included "promotion of genetic improvement" (0.90), "establishment of national Based on the research findings, two controllable pillars—data-driven infrastructure and technological innovations—are recommended as the most effective factors for enhancing agricultural water productivity.
