The distribution of arable land drought in the Belt and Road area, January, 2001

Brief introduction

Due to the high frequencies, long duration, wide range of impacts, and a large number of accompanying disasters, droughts have been known to cause great economic losses to the national economies, especially to agricultural production, in many countries. Considering the urgent demand for the spatio-temporal distribution of drought disasters over long periods of time in the Belt and Road region, this knowledge service utilized the Tropical Rainfall Measuring Mission satellite (TRMM) precipitation data to calculate the monthly spatio-temporal distribution of drought in the Belt and Road arable area from 2001 to 2013 based on the Precipitation Abnormity Percentage drought model.

Function

The application of the spatio-temporal distribution of arable land drought in the Belt and Road has been released. Considering the urgent demand for drought disasters over long periods of time in the Belt and Road region, this application shows the monthly spatio-temporal distribution of the drought from 1998 to 2015 with the Precipitation Abnormity Percent-age drought model.MapServer is used to release Web Map Service (WMS) referring the international specification. The Combination of data and MapBox tiles has been used by LeafletJS to generate the map view. When the app page opened, the satellite map image could be visualized as the map service.

Instruction

Selecting GIS data operation in the sidebar navigation, you can see the corresponding options (year and month) and click the drop-down arrow to display the year and month lists, including the years from 2001 to 2013, and the months from January to December. Documents and information are classified by label control. Additional links for related pages are listed in the app page for user to get more readings.
