摘要

Crop production is linked with climate parameters and resultant Crop Water Requirements (CWR). In this study the temporal shift in rainfall, temperature, and their impact on CWR was evaluated. Thirty years data (1991 to 2020) of climatic parameters and cropping data of four major crops: wheat, rice, sugarcane, and maize were collected to assess impact of climatic shift on CWR. It was found that maximum and minimum temperatures are trending northeastward, while rainfall ranges are moving northeastward in a spatial sense. Lahore and Gujranwala had above-average temperatures (34–36.72 °C), whereas Okara had 160 mm, Toba Tek Singh 130 mm, Faisalabad 110 mm, and Sahiwal 80 mm of monthly rainfall, among other noteworthy variations. There were three time windows (TW) i.e., TW1: 1991–2000, TW2: 2001–2010, and TW3: 2011–2020, to determine trends in CWR across time. The order of CWR in Okara and Lahore in August was TW3 > TW2 > TW1, whereas in July the inverse was true. As a result of Gujranwala’s deviation, TW1 < TW2 < TW3. While Faisalabad followed regional patterns in all months until August, when it showed equal CWR for TW2 and TW3. Sahiwal followed tendencies similar to Okara and Lahore. In July and August, Toba Tek Singh showed a declining tendency, although the general patterns were similar to other districts. Findings from this research stress the importance of climate-resilient agriculture planning and adaptive water management in the study area for reducing the social and economic toll of extreme weather.
