Drought declaration is crucial since it signifies the beginning of states's response to drought. India's current drought management policy is specified in the Manual for Drought Management 2016. While the manual provides comprehensive guidelines to states and regional Drought Monitoring Centres (DMC's) for monitoring and declaration of droughts, assessing the current drought detection framework and its suitability in different regions has been lacking. Using gridded products of precipitation, soil moisture, and remote sensing indicators, we examine the differences between detected and declared droughts for all the districts in India during the 2000–2017 period. Comparison of detected and declared droughts show a higher probability of detection (POD) in central India. In contrast, lower POD was found in regions of high drought susceptibility like Rajasthan, Andhra Pradesh and Karnataka. Large differences between the detected and declared droughts were identified in the irrigated regions of Punjab and Gangetic Plain. The use of Solar-induced chlorophyll Fluorescence (SIF) instead of Normalized Difference Vegetation Index (NDVI) as a remote sensing indicator improved drought detection (based on POD and false alarm ratio, FAR) in central and western parts of India. The framework specified in the drought manual detects most of the major droughts that affected a large part of the country. However, regional droughts in Rajasthan, Gujarat, and Karnataka are frequently missed. Finally, we highlight the limitations in the existing drought monitoring framework and opportunities for its enhancement.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"14 ","pages":"Article 100104"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42660591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In India, more than 75% of the annual flows occur in rivers during four monsoon months and this is also the period when flooding takes place. The major causes of water insecurity in India are: (a) highly skewed water availability, variability and increasing demands, (b) poor water quality and issues arising due to these, (c) weak water governance, and (d) emerging challenges due to climate and land-use cover changes. This paper focuses on the first cause of floods. I have argued here that flood flows should be viewed and harvested as a resource to be conserved and utilized to overcome water shortages rather than to be passed to oceans as quickly as possible. Conservation and diversion of flood flows can help in overcoming water shortages, variability and disaster management. Both infrastructure and governance will have to be expanded to achieve this objective. To that end, the paper presents suggestions to conserve, divert, and utilize flood flows.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"14 ","pages":"Article 100105"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48841079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim was to (1) provide regional data for flood risk managers and water resources planners, (2) develop a nationally consistent approach to identify the robustness of considered measures for a variety of conditions which (3) is applicable in both river basin management planning and flood risk management planning. According to the feedback from practitioners in regional flood management groups as well as planners, the framework helped to raise new thoughts and to open new perspectives in the planning process and may hence influence the practice of planning of flood risk reduction measures. Also, it was found useful to have access to regional, tailored data on hydrological impacts in the planning process and during communication with stakeholders. The described methodology has been used in the preparation of the 2nd version of flood risk management plans and for the 3rd version of river basin management plans.
