First, water shortage and serious drought resulting from climate changes have greatly reduced annual world grain production. Second, lots of arable land has been lost due to the rapid development of industry and urbanization. To make the situation worse, in many countries, negative government policie...

Based on Equation (9), the average sediment magnitude measured in the reservoir is 62 cm, thus 36% higher than the mean raster average (40 cm). Hence, the interpolation can lead to an underestimation of the sediment stock of up to 36%. Another important factor, which can affect the sedi...
The mean value of the standardized data is 0 and the standard deviation is 1. It can give different features the same scale, which is conducive to the reliability of the results. Suppose there are m evaluating objects and n indicators. The indicators value matrix can then be formed as: ...
