📄 Abstract
In the recent period the most important challenge faced by researchers is to have a better knowledge about climate change at a regional level. The change in climate at local or regional level is unequal and it has a localized intensity. Therefore it is identified at a local scale. Temperature and Precipitation are the two important variables of climate, which are more responsible for climate change in local level and required to give more concerned about it. Here we take one climatic variables i.e. Rainfall for our study in the 7 Coastal districts of Odisha. The state of Odisha is located in the east coast of Indian peninsula. Most of the agricultural region of odisha is located in the coastal belt of Odisha. Agriculture plays a vital role in the economy of Odisha, which is highly influenced by rainfall. Any change in pattern of rainfall cause by climate change can adversely affect the production of crop. Therefore in the current study, an attempt has been made to observe spatio-temporal rainfall change and its trend over a period of 119 years (i.e. 1901-2019). For this study we used the non-parametric trend analysis techniques, namely Mann kendall test and Sens slope estimator for observing the trend direction and magnitude of the change over the 7 coastal districts of odisha i.e. Balasore,Bhadrak,Ganjam,Jagatsinghpur, Kendrapada, Khorda and Puri. The observed variation in rainfall revealed that, the monsoon season has maximum contribution to annual rainfall and it does not have any strong trend over the coastal areas of Odisha in study period of time. The outcomes of the study gives information on rainfall trends and impact of climate change in coastal districts of Odisha which will be helpful for a water resources manager in the planning and management of water resources for sustainable development and particularly for the benefits of agriculture of coastal odisha.
