楼主您好,这是我的翻译版本,希望对你有所帮助!

翻译： 这样看来,农业的兴起并非由于食物短缺——这一世界人口猛增带来的问题,因为这曾在全球范围内发生过.
分析：当长句不容易被理解时,可以适当调整句子结构,将其转换成容易被识别的熟知句型后在进行翻译：
1. It seems likely that
agriculture didn't emerge in responceto a food shortage.
2. the food sortage was brought on by a worldwide population crisis.
3. the worldwide population crisis once developed.
4. the whole world was occupied by the crisis.

如有不详尽,欢迎追问；
如满意,望采纳~
谢谢!
