Climate Change Impacts On Soil Resources And Crop Productivity A Case Study Of District Jacobabad Sindh Pakistan

Climate change has multifarious impacts on soil water and yield production. Considering this important aspect a research study was carried in order to find out climate change impacts on soil resources and crop productivity in Jacobabad with aim to develop innovative soil and crop management practices as to minimize on-farm climate change impacts in the area. In our study we tried to assess climate change impacts on soil salinity level organic matter decomposition rate soil moisture relationship outbreak of plant diseases and insects pest in the area. Our study revealed a close relationship between climate change and soil health and cop productivity of the area. Currently 60 soils of the study area are moderately saline having 7.8 pH and about 20 soils are sodic saline soils having ph 8.5 respectively. Organic matter content is less than 0.002 across study area. Moreover plant diseases such as wheat rust bacterial blast powdery mildew and insect pests like aphid are occurring widespread. All these factors have left serious implications on the crop production. According to our findings that 40 to 45 cereal crop production such as of rice and wheat has declined. Currently there is dire need to adopt innovative on farm practices to mitigate climate change impacts on soil resources of the area.
