N2  - Agriculture and international food security are at unprecedented risk from climate  change. In agriculture and the national economy, rice production plays an extremely  important position in Pakistan. Therefore, Pakistan needs an hour to determine the  effect of climate change on rice productivity and to lessen the impacts by using  agricultural adaptation measures in district Sialkot. District Sialkot has the 2nd largest  production of rice in Punjab, Pakistan. The main purpose of this study is to assess the  effect on rice production of the future climate and to evaluate the different adaptations  to agriculture to mitigate climate change effect using the DSSAT model.  The future Climate Scenarios were built in three MCGs CCSM4, MIROC5 and  MPI-ESM-MR and downsized using the Quantile Mapping Bias Correction Technique  in terms of projections from RCP4.5 and RCP 8.5 for the periods 2010-2039,  2040-2069 and 2070-2099. In future time slices, the district's maximum and minimum  temperatures are to rise respectively by 0.8 to 3.7 DC and by 0.9 to 3.9 DC. The annual  rainfall is also projected to decline by 1 to 9.5%. Similarly, The DSSA T model has been  used to predict the effect on yield of potential climates. Results show that the production  for all scenarios and all periods of time, relative to base yield is reduced by 0.97 to 22  percent. This decrease of yield can be offset by opting for various agricultural  adaptation measures.  It was found that the practiced agricultural adaptation measures of proper management  of nutrients, irrigation, use of alternate rice variety and shifting the planting dates have  been helpful in mitigating the impact of climate change. Late transplanting of rice  increases the yield by 7.3 % to 16 % in future. Increasing the fertilizer application rate  enhances the yield from 0.5 % to 28.10 % under future climate. Shifting to alternate  varieties also increases the yield in future up to 27 %. Deficit Irrigation increases the  yield from 3 % to 23 % for the future. Based on these findings change in planting dates  can therefore be beneficial to adapting rice cultivation to climate change scenarios in  District Sialkot of Punjab, Pakistan, through deficit irrigation, adequate Nutrient  management and adoption of alternative rice cultivars.
