PhilRice Develops Climate Risk Maps to Help Farmers Prepare for El Niño

 

The Philippine Rice Research Institute (PhilRice) is strengthening climate preparedness in the agricultural sector through a new risk assessment platform designed to help rice farmers make informed planting decisions during El Niño.

The initiative uses Vulnerability Risk Assessment maps to identify communities facing potential drought conditions and recommend appropriate agricultural interventions based on their level of exposure. Rather than relying on generalized weather forecasts, the system provides localized assessments that can help farmers determine whether to proceed with rice cultivation, modify planting schedules, diversify crops or pursue alternative sources of income.

PhilRice Data Analytics Center head Jesusa Beltran explained that the assessment framework examines three critical factors: drought exposure, crop sensitivity and adaptive capacity.

These indicators provide a broader picture of agricultural vulnerability by incorporating climatic water balance, crop water stress, growth stages, available irrigation, farming practices and the resources accessible to individual farmers.

The resulting maps use four color classifications to guide decisions by farmers and local government units (LGUs).

Green areas: Continue planting with efficient water management

Communities classified as having low vulnerability are encouraged to maintain their planting activities while adopting practices that conserve available water.

Recommended measures include alternate wetting and drying, a rice irrigation technique that allows fields to undergo controlled periods without standing water, alongside regular monitoring of weather advisories.

Yellow areas: Strengthen preparation and reduce exposure

Farmers in moderately vulnerable locations can still proceed with rice cultivation, but additional precautions are necessary.

PhilRice recommends coordinating with LGUs to review planting schedules, obtaining crop insurance, selecting drought-tolerant and early-maturing rice varieties, and identifying alternative water sources before water shortages become more severe.

Orange areas: Consider alternative crops

Locations facing high drought vulnerability may need to temporarily reduce rice cultivation and transition to crops requiring less water.

Suggested alternatives include corn, mung bean, watermelon and pechay. These options could help farmers sustain agricultural production while limiting their exposure to water-related losses.

Red areas: Prioritize livelihood protection

Communities facing severe drought conditions and significant water shortages may be advised to postpone rice planting altogether.

Instead, farmers can explore other income-generating opportunities, including livestock production and alternative livelihood activities, until conditions become more favorable for rice cultivation.

Beltran emphasized that the maps are intended to translate climate risk information into practical decisions at both the farm and community levels. For LGUs, the assessment can also support agricultural planning, resource allocation and the timely delivery of assistance to vulnerable farming communities.

PhilRice agronomist Ailon Oliver Capistrano added that farmers who continue rice production may consider hybrid rice varieties and other yield-enhancing technologies to help offset possible production losses.

The institute also identified several water-efficient approaches that can strengthen farm resilience, including direct seeding, solar-powered irrigation, rainwater harvesting and integrated farming systems.

By matching agricultural strategies to local drought conditions, PhilRice aims to help farming communities avoid unnecessary production losses while making better use of limited water resources. The approach recognizes that preparing for El Niño requires more than anticipating dry weather. It demands timely decisions about what to plant, when to plant and how to protect farmers' livelihoods.
