Please help and fast How did the climate and geography of Central Asia influence the rise of nomadic pastoralist societies?

The climate and physical features of Central Asia were major influences on the growth of nomadic pastoralism in the region. Central Asia's climate is mostly either semiarid or dry, and the region's features include deserts, grasslands, and mountains. Nomadic pastoralism tends to develop in places that have harsh weather and limited water, which discourages agriculture. Because of such conditions, herders would move their herds and flocks in search of food and water. This often occurred seasonally – for example, they allowed their herds to graze in the mountains during the summer but moved to the grasslands or desert shrublands during winter.
