Manual for Drought Management: Drought Declaration Explorer

Instructions:

1. Select three impact indicator categories from the four available. Note: The app will display a warning if the wrong number of categories is selected.

2. Select impact indicators from your chosen categories. These will be used in the drought declaration calculation, along with Rainfall, which is a mandatory indicator.

3. Select district (Drought Declaration Tab) or declaration-period (Drought Declaration Maps Tab).

4. Press the Update Declaration button to display drought declaration outputs. Use the Drought Declaration tab to view the outputs as district time-series, or the Drought Declaration Maps tab to see declaration period maps.

This app has been developed collaboratively between UK Centre for Ecology & Hydrology , National Institute of Hydrology Roorkee and IIT Gandhinagar as part of the SUNRISE project (NERC Grant Reference: NE/R000131/1).


Welcome to the Manual for Drought Management: Drought Declaration Explorer.

The app visualises reconstructed drought declarations in the Maharashtra State, as set out by the Manual for Drought Management (2016) and Amendment in the Manual for Drought Management (2018) . You can find out more about the data, processes and assumptions made in the calculations of these declarations in the methodology document, and by visiting the Further Information tab.

Please use the tabs at the top of the page to navigate through the app, and use the instructions on the left hand side of the page to help you explore reconstructed Maharashtra drought declarations.

Our thanks extend to the India Meteorological Department (IMD) for providing us with rainfall data, which has been vital in the calculation of drought declarations.

For enquiries about data or the development of the app, please contact project lead Dr Simon Parry .


Please Note: This app is for demonstration purposes only and must not be used for any decision making applications.

Please Note: Rainfall is a mandatory indicator and has been included by default in the drought declaration process.

2. Select Impact Indicators from your chosen categories:

Please Note: Agriculture category contains no choice, so Crop Area is used by default if selected.

4. Press button to load new drought declaration outputs.

Manual for Drought Management (2016)

The app declares reconstructed drought events following the methods in Manual for Drought Management (2016) , which can be viewed online by clicking here . The manual has been followed as closely as possible for the calculation of all indicators, and the combinations that lead to drought declarations. Where the manual is unclear, or not possible to follow due to data limitations, best practice has been followed with guidance from Dr Rajendra P Pandey.

Maharashtra State has been used as a case study region, and declarations between 2006 and 2015 have been made on a district level. This spatial domain has been chosen as it allows local hydrological and climatological conditions to be represented whilst ensuring data is available across the whole state.
