So pastoralism is a more extensive lifeway than farming is.

因此，畜牧业是一种比农业更广泛的生活方式。

Pastoralism is a lifestyle in which economic activity is based primarily on livestock.

游牧是一种生活方式，其经济活动以饲养牲畜为主。

As the archaeologist Roger Cribb puts it, "The greater the degree of pastoralism, the stronger the tendency toward nomadism."

正如考古学家罗杰·克里布所说的：“畜牧化程度越深，游牧化生活的趋势就越大。”

In particular, pastoralism favors a mobile lifestyle, and this mobility helps to explain the impact of pastoralist societies on this part of the world.

特别是，游牧主义倾向于一种流动的生活方式，这种流动性有助于解释游牧社会对世界这部分产生的影响。

This is particularly true of the horse pastoralism that emerged in the Inner Eurasian steppes, for this was the most mobile of all major forms of pastoralism.

在欧亚大陆内部大草原上出现的马的游牧主义尤其如此，因为它是所有主要游牧形式中最具流动性的。

The emergence and spread of pastoralism had a profound impact on the history of Inner Eurasia, and also, indirectly, on the parts of Asia and Europe just outside this area.

畜牧业的出现和传播对欧亚大陆内部的历史产生了深远的影响，同时，也间接地影响了欧亚大陆以外的亚洲和欧洲部分地区。

Perhaps even earlier, there had emerged on the steppes of Inner Eurasia the distinctive types of pastoralism that were to dominate the region's history for several millennia.

也许更早的时候，在欧亚大陆内部的大草原上就出现了独特的游牧文化，这种文化主导了该地区几千年的历史。

It is the use of horses for transportation and warfare that explains why Inner Eurasian pastoralism proved the most mobile and the most militaristic of all major forms of pastoralism.

正是马在交通运输和战争中的使用，解释了为什么欧亚大陆内部的游牧主义是所有主要游牧形式中最具流动性和最具军国主义色彩的。

The herd size is what makes pastoralism a bit economical, but once the herd size shrinks it becomes really uneconomical.

让游牧很经济的是畜群规模，但是一旦畜群规模缩小，游牧就会变得相当不划算。

The most vulnerable people are world's poorest, 70 per cent of whom depend on subsistence farming, fishing or pastoralism for income and food.

最脆弱的人是世界上最贫穷的人，其中70％依靠自给农业、渔业或畜牧业获得收入和粮食。
