Advisories
As rainfall gradually increases and vegetation becomes denser, farmers are encouraged to prepare upland fields for rice, vegetables, and other crops to reduce flood risks and improve yields. Proper field layout and drainage channels should be established to prevent waterlogging. Farmers are also advised to plant drought- or water-tolerant crop varieties, regularly monitor crops for stress and disease, and irrigate when necessary. Livestock owners should move animals to safer upland areas, maintain proper housing and hygiene, provide clean drinking water, and monitor animals regularly for signs of illness.
