1. The American West, characterized by plateaus and mountainous regions, predominantly experiences arid and semi-arid climates, including highland and Mediterranean climates. This terrain and climate are conducive to the extensive grazing of livestock across vast meadows.
2. The sparsely populated nature of the Western United States provides ample pastureland for livestock raising. Moreover, certain areas, due to their climatic conditions, are suitable for crop cultivation, such as cotton and corn.
3. These crops require abundant water during their initial growth stages, which aligns with the dry season experienced in the Western regions. Therefore, irrigated agriculture becomes particularly crucial here.
4. Thanks to the United States' advanced irrigation technologies, the Western regions have gradually developed irrigated agriculture. The sophistication of these technologies allows for sustained agricultural production even in arid conditions.
5. The primary factors contributing to the suitability of the American West for the development of livestock farming and irrigated agriculture are its unique climate conditions, natural environment, land area relative to population, and the availability of advanced agricultural technologies as well as market demand.
