Niğde İli Tarımsal Su Ayak İzi Dinamiklerinin Yenilikçi Trend Analizi Kullanılarak Değerlendirilmesi

Abstract

İklim değişikliği ve artan gıda talebi, yarı kurak tarım havzalarındaki sınırlı su kaynakları üzerinde ciddi bir baskı oluşturmaktadır. Bu çalışma, Niğde İlindeki bitkisel üretimin sürdürülebilirliğini değerlendirmek amacıyla Su Ayak İzi (WF) yaklaşımı ile Yenilikçi Trend Analizi (ITA) yöntemini entegre etmiştir (2005-2024). Sonuçlar, verimlilik ve ölçek arasında kritik bir hidrolojik paradoks ortaya koymuştur. Artan atmosferik su talebine (S=79.82) rağmen, modern sulama teknolojileri ve yüksek verimli çeşitlerin kullanımı sayesinde birim WF istatistiksel olarak anlamlı bir azalma eğilimi (S=-348.23) göstermiştir. Ancak, bu teknik verimlilik havza ölçeğinde mutlak su tasarrufuna dönüşmemiştir. Aksine, Bölgesel WF hacmi belirgin bir artış trendi (S=3.43) sergilemiştir. Bu hidrolojik genişleme, nüfus artışı ve yükselen ekonomik talep tarafından tetiklenen belirgin bir geri tepme etkisine işaret etmektedir. Analizler, verimlilik kazanımlarından elde edilen su tasarrufunun yeraltı suyunu korumak yerine ürün desenini değiştirmek için kullanıldığını göstermektedir. Çalışma döneminde buğdayın payı %55’ten %38’e gerilerken, Patates (%18) ve Kuru Fasulye (%7.2) gibi katma değeri yüksek ancak yoğun Mavi Su tüketen ürünlerin ekim alanları hızla genişlemiştir. Sonuçlar, teknolojik modernizasyonun tek başına yetersiz olduğunu; yeraltı suyu üzerindeki baskıyı hafifletmek için politikaların nicel tahsis kotaları ve stratejik planlama ile desteklenmesi gerektiğini vurgulamaktadır.

Assessment of Agricultural Water Footprint Dynamics of Niğde Province Using Innovative Trend Analysis

Abstract

Climate change and increasing food demand exert unprecedented pressure on limited water resources in semi-arid agricultural basins. This study integrated Water Footprint (WF) and Innovative Trend Analysis (ITA) to evaluate the sustainability of crop production in Niğde Province (2005-2024). Results revealed a critical hydrological paradox between efficiency and scale. Despite increasing atmospheric water demand (S=79.82), the unit WF showed a significant decreasing trend (S=-348.23), driven by modern irrigation technologies and high-yielding varieties. However, this technical efficiency did not translate into absolute water savings on the regional scale. On the contrary, the Regional WF volume exhibited a distinct increasing trend (S=3.43). This hydrological expansion points to a distinct rebound effect driven by population growth and rising economic demand. Analyses indicate that water savings from efficiency gains were utilized to alter the crop pattern rather than to conserve groundwater. During the study period, the share of wheat declined from 55% to 38%, while high-value but Blue Water-intensive crops such as Potato (18%) and Dry Bean (7.2%) expanded rapidly. Results highlight that technological modernization alone is insufficient; policies must be supported by quantitative allocation caps and strategic planning to alleviate pressure on groundwater.
