Here, we attempted to identify ideal ecological niche for cumin cultivation in India in the future climate scenario by adopting an integrated approach of climate analogues and soil suitability. This will help policy makers for area expansion to generate more revenue as cumin has huge export potential. Climate analogues tool, a web-based tool developed by the Research Programme on climate change, agriculture and food security (CCAFS) helps to identify, connect and map sites with statistically similar climates across space and time. Efficient cumin production zones in India were identified based on relative spread index and relative yield index which were used as the input/reference site for finding the analogues sites. Rainfall and temperature were the main climatic variables used in the study under SRES A1B emission scenario. The results showed a total of 453 analogues sites (districts) identified by 14 reference sites used in the study. The analogues sites identified by the tool were further corroborated with the soil suitability of the location and refined analogues sites which included soil suitability for cumin cultivation (337 analogues sites out of 453) were identified. Rainfall trend analysis from the rainfall data of past 110 years indicated that analogues sites are showing the rainfall trend suited for cumin cultivation. This is the first report on the use of climate analogues tool to identify analogues sites with soil suitability and rainfall trend analysis of the identified analogues sites. |
