The kanji 需 is a 形声文字 (keisei moji), a phonetic-semantic compound character. The character combines two elements: 雨 (ame, "rain") on top, which acts as the phonetic component, suggesting the sound and also potentially referencing something coming down or being provided. The bottom component is 而, which gives it its meaning. Thus, it initially represented the need for rain for crops, which developed into a broader sense of requirement or demand.
