Corrections in bold.
Words in red: omit (leave out).

This terrible consequence is due to the* bad weather. When it will rain/it rains is determined by the nature. Abudant rainfall is central to crops to grow on nicely. In contrast, if there is no regular precipitation, farmers' life will be take a bad knock. The farmers were deprived of all their rights by harsh policy. And this is the worst thing, which can even destroy their lives completely.

*the: if you mean some known period of bad weather, for example the bad weather that destroyed this year's crops, then use 'the'. If you mean bad weather in general, don't use anything.

You write well, but you need to work on a few things before you can write much better.
