In the agricultural heartland of Maria Aurora, Aurora province, a quiet transformation is taking place. Long known for rice farming, the region is now witnessing an increasing number of farmers switching to sweet potatoes, driven by declining palay prices and rising production costs. At a time when the farm gate price of palay has dropped to ₱12–₱15 per kilo, many producers are finding that they can no longer break even.
According to the Philippine Statistics Authority, the average cost of producing palay in the Philippines is approximately ₱11.76 per kilo, but this does not account for recent increases in inputs like fertilizer, fuel, and labor. With some regions reporting production costs as high as ₱14–₱16 per kilo, farmers selling at the current market rate are facing negative profit margins.
In contrast, sweet potatoes (Ipomoea batatas) present a more resilient and cost-effective alternative. They require less irrigation, thrive in hotter and drier conditions, and have a shorter growing period compared to rice. Moreover, sweet potatoes are less input-intensive, with lower requirements for pesticides and fertilizers, making them a more sustainable choice in both economic and environmental terms.

Farmers in Maria Aurora noted that with changing climate patterns and reduced water availability, the switch to sweet potatoes is also a form of risk management. “It’s not just about cost,” one grower explained. “It’s about survival. We can’t afford to wait for better rice prices that may never come.”
Globally, sweet potato production has gained attention as a climate-resilient crop, especially in regions prone to drought and heat stress. The International Potato Center (CIP) has identified sweet potatoes—particularly orange-fleshed varieties rich in beta-carotene—as a strategic food security crop for developing economies. In 2023, the Philippines produced over 500,000 metric tons of sweet potatoes, mainly for domestic consumption and food processing.
However, transitioning from rice to root crops comes with challenges. Infrastructure, market access, and consumer demand for sweet potatoes need to be developed to support expanded production. Post-harvest handling and storage are also critical, as root crops are more perishable than grain. Local government units and agricultural extension services will play a key role in facilitating this shift by providing technical support, market linkages, and training on diversified farming systems.
The shift from palay to sweet potato farming in Maria Aurora reflects broader pressures facing traditional rice growers in Southeast Asia: volatile prices, high input costs, and climate uncertainty. While not a universal solution, sweet potatoes offer a promising alternative that combines resilience with market potential. With strategic support, this crop could help safeguard farmer livelihoods and contribute to a more diversified and sustainable agricultural system.
