Gansu has barren land and vast mountains. Why not develop animal husbandry and focus on planting?

Due to the special conditions in Gansu Province, Gansu Province has a continental arid climate, and most of the land in the province is dry and short of water. The development of animal husbandry needs land to grow pasture and a lot of water (for livestock). Now Gansu province does not have this condition. However, most of the land in Gansu Province is mountainous and suitable for planting. There is another important reason: the land desertification in Gansu Province is serious, and the wind and sand erosion is serious. The granaries in Hexi Corridor need to be protected, so planting is still used to curb desertification. Protect local agricultural development.

Thank you. I hope I can help you.
