Does climate impact vary across time horizons? A time–frequency analysis of climate-crop yields in India

Climate change is a major concern the world over more so for predominantly agrarian country like India. In this paper we analyze time horizon dynamics of crop and climate variables at regional level in We also co-movements yields with temperature rainfall to observe coherence across heterogenous horizons. employ Bai-Perron structural break Continuous wavelet transform methods on yearly data seven variables. Observed are analyzed from 1956 2010 un-divided state Andhra Pradesh, Breakpoint analysis shows an increase around 1.0° two observed points. Rainfall depicts no systematic fluctuations being largely random. The framework wavelets-based time–frequency employed study captures heterogeneous horizons, allowing one impact both short longer time-horizons. Wavelet based exhibited significant co-movement between climatic Given shifts patterns subsequent horizons level, policy makers scientists should design specific locally viable adaption mitigation policies tackle crops livelihoods.
