Social Media plays a vital role in the context of drought risk management system. This paper focuses on the significance of social media in drought risk management. We analyzed the tweets polarity by using the R Tool and Python and compared the results. We tries to extract the opinion of users on drought in social media and its impact.

About 80 countries comprising 40 percent of world’s population already suffer from serious water shortages [1]. This will lead to various problems related to social, political and environmental costs that indirectly affect the socio economic condition. Nearly 44 million people in India are affected by water quality problems either due to pollution, the prevalence of fluoride, arsenic and iron deposits in groundwater, or due to ingress of sea-water into groundwater aquifers [1]. Millions do not have enough water, particularly during summer months, and women and girls have to walk long distances to fetch water. In the search for water, people are going deeper into the ground, lowering the groundwater table and leaving wells dry. In India, the availability of surface water in the years 1991 and 2001 were 2309m3 and 1902 m3. However, it has been projected that per capita surface water availability is likely to be reduced to 1401 m3 and 1191 m3 by the years 2025 and 2050, respectively. The Per capita water availability in the year 2010 was 1588 m3 against 5200 m3 of the year 1951 in the country. [2] Sever actions are needed to preserve the valuable resources in nature. We need to focus more towards the management of water. Water management is the management of water resources under set policies and regulations. Water, once an abundant natural resource, is now becoming a more valuable commodity due to droughts and overuse[3].Lot many research are going on to optimize the use of water and in minimize the environmental impact of water use on the natural environment. One of the biggest natural water disaster is Uttarakhand disaster 2013. According to the Indian Meteorological Department, rainfall in Uttarakhand during the week of 20th to 26th June 2013 has been in excess by 37 per cent of normal rainfall. During this period, the state received 73.3 centimetres of rain while the normal rainfall is usually 53.6 centimetres. On 1 July 2013, the IMD has warned of heavy rainfall over Uttarakhand (locations not specified) during the next 48 hours. Uttarakhand 2013 damage details [4]  822 Deaths (official estimates)  1,800 Missing persons  2,232 Fully damaged houses  154 Damaged bridges  1,520 Damaged roads In Maharatra‘s Marathwada region the year 2015 came up as a drought affected year. This is much worse than that in the year 1972 and year 2004. There is an alarming rise in number of farmers’ suicides. As many as 2,234 farmers’ have committed suicides in year 2015 and 1981 in 2014, and 1296 in 2013 in Maharashtra (Sunday Times of India, Aurangabad Oct 11, 2015). The highest suicides recorded in Vidarbha that is 11, 08, followed by Marathwada 766, Nashik division 303 and Konkan region has one case of farmer suicide. The major reasons are failure of the monsoon, ineffective implementation of crop insurance and planning of drought mitigation measures that includes short term and long term basis. [5] II. Natural Disaster – Drought Drought occurs over most parts of the world, even in wet and humid regions. This is because drought is defined as a dry spell relative to its local normal condition. On the other hand, arid areas are prone to drought because their rainfall amount critically depends on a few rainfall events [6].
