Assessment of Climate change impacts on wheat and Barley production quality and quantity in Palestine
Author(s): Imadeddin Albaba
Abstract: The wheat and Barley cultivation in the West Bank-Palestine show a distinct Mediterranean climate with most of the rainfall occurring in the winter months. The main detrimental factor limiting plant production in this region is rainfall. Due to clearing of native vegetation, dryland salinity is a major problem in Hebron and east Jenin districts. Since the 1970s years the West bank has experienced a significant decrease in winter rainfall. Across Fifteen sites, growing season rainfall (September to May) decreased by an average of 11% and the sum of rainfall in September and October decreased by 45%. Despite the large decline in rainfall, yields based on the actual weather data did not fall. These results were due to the rainfall changes mainly occurring in September and October, a period when rainfall often is less than crop demand. The findings will have significant implications for estimates of future climate change impacts in the West Bank with changes in rainfall causing proportional impacts on production, where proportionality is often presumed.
