Assessment of impacts of climate change on rice and wheat in the Indo-Gangetic plains

In this paper, the climate change scenarios of A2 and B2 for 2070-2100 time scale (denoted as 2080) several key locations India its impact on rice wheat crops based regional model (PRECIS) were described. The PRECIS projects an increase in temperature over most parts especially IGP (Indo-Gangetic Plains), region that presently experiences relatively low temperatures. Extreme high episodes rainfall intensity days are projected to become more frequent monsoon is also increase. Rabi (mid Nov-March) season likely experience higher which could hence threat really require their growth. Climatic variability both scenarios. All these changes reduce yields Indo-Gangetic plains India. It there will be number years with occurs towards end century. Such yield reductions due mediated through reduction crop duration, grain filling duration. loss scenario compared B2. These quantitative estimates still have uncertainties associated them, largely projections, future technology growth, availability inputs such water irrigation, management genotype. projections nevertheless provide a direction productivity
