ตัวอย่างการใช้รูปกริยาที่ผันตามประธานในบทความด้านการเกษตร
Adaptation to climate change is taking place in the cultivated areas of north-eastern Khon Kaen Province where the total planted area of rice was approximately 404,432 hectares or nearly 64% of total crop areas in 2007. Here, most small farmers face extreme drought in the middle of the dry season and floods in the early part of the wet season. At the same time, rice prices have fluctuated in recent years as a result of global uncertainty and therefore there have been limited opportunities for farmers to increase their incomes.
