The program meant to raise funds for farmers in the west of China proves to be an effective approach to solving the problem of poverty.
划线部分为过去分词短语作定语。

为什么用过去分词 meant，是因为逻辑主语 the program 与它是被动关系，“这个计划是被人们用来做某事的；旨在做某事的”。演变如下：

We mean the program to raise funds...

变被动句：

The program is meant to raise funds...

变成定语从句：

The program which is meant to raise funds for farmers in the west of China proves to be an effective approach to solving the problem of poverty.

变成分词作定语：
The program meant to raise funds for farmers in the west of China proves to be an effective approach to solving the problem of poverty.
