Assessing Crop Yield Sustainability under the Climatic and Bioclimatic Change in the Area of Palestine


We analyzed plant production such as olive, grape and fig in several Palestinian Occupied Territories, and studied the correlation analyses between productions and climatic, bioclimatic features in the territory. This work examines the following climate factors: average temperature, precipitation, soil water reserve and water deficit; and bioclimatic parameters such as compensated thermicity index, ombrothermic index and continentally index. The data used were from nine meteorological stations of the Palestinian Meteorological Department. The study was based on the correlation analyses between olive, grape and fig production in nine plots: Hebron, Ramallah, Nablus, Jenin, Jericho, Bethlehem, Jerusalem and Tulkarem over fourteen years. The analysis of variance revealed a significant influence of the variables temperature and compensated thermicity index on the production of olive and fig, and a low influence on grape production. When we applied canonical correspondence analysis (CCA), the Nablus, Jenin, Jericho and Gaza plots were most affected by the climate factors as temperature, and bioclimate factors as compensated thermicity index, whereas, the Hebron, Bethlehem, Jerusalem, Tulkarem and Ramallah plots showed the influence of ombrothermic index, continentally index, precipitation, water deficit and soil water reserve.
