Climate change, a global phenomenon is affecting the production and productivity of all food crops, including rice.To sustain the future food production ICAR has initiated a massive program National Innovations on Climate Resilient Agriculture(NICRA) under which IIRR is identified as one of the nodal net work centre. A part from the anthropogenic and human involvements, some of the agriculture practices are leading to contribute change in climate. Nevertheless of food security, agriculture practices followed to cultivate rice are attributed to influence climate and therefore, ICAR has decided to pin point the irrelevant practices to mitigate climatic effects and also preparedness to develop resilient cultivars. The moderate estimates of methane and nitrous oxides produced through fertilizer N application) are 3.3 and 0.14 mt from 44 mha rice area under cultivation. Other dimension of climate change includes plant health by shifts in pest and disease organisms. Changes in phenology and life cycles, population, migratory behaviour, alteration in crop-pest synchrony, natural enemy-pest interaction are a few which need to be studied. Brown plant Hopper (BPH), is one such pest in rice known for its seasonal migration and strategy pattern of life. These are expected to lead to temperature raise for which the rice crop is sensitive and also demand for fertilizer nitrogen for sustainable rice production. The thrust areas of research are developing heat tolerant rice genotypes, enhancing nitrogen use efficiency in rice and modelling BPH under climate change are tackled at DRR under this national mission
