What is it about?
Climate change, population explosion and desire for economic growth are highly affecting several societies and ecosystems thereby causing several natural hazards. Drought, one of the most pervasive, recurring natural hazard in all climatic zones worldwide had a significant effect on ecological environment and agricultural production. The estimation and prediction of such a natural hazard is a prerequisite in a country like India, as it has diverse climatic conditions, proliferating population, fragile ecosystems and rapidly developing industries and economies that are leading to climate change and drought disasters. Recent studies even highlighted that around 18 meteorological droughts and 16 hydrological droughts have occurred over India in the past four decades. Hence, in the current study we have proposed and tested two approaches for estimating and predicting the drought events based on pre and post-integration of drought indices using machine learning algorithms.

Why is it important?
This research provides insights to the researchers for selecting (i) SPP that has the capability to detect precipitation and drought events accurately (ii) a machine learning algorithm that can be employed in any region for enhancing the drought predictions and (iii) an approach for estimating drought when machine learning algorithms are applied.
