โ€œSa bawat karne na napoproseso, kabuhayan ay unti-unting umaasenso โ€” sama-samang pag-unlad para sa mas matatag na samahan ng mga irrigators.โ€ Muling nagsagawa ang Division I sa NIA MARIIS ng dalawang araw na Livelihood Training on Meat Processing para sa mga miyembro ng ibaโ€™t ibang Council of Irrigators Association (CIA) sa nasasakupan nito. Isinagawa ang naturang pagsasanay sa pakikipagtulungan sa Southern Isabela College of Arts and Trades na nagbibigay ng accredited trainings sa Santiago City.

Layunin ng aktibidad na mabigyan ng dagdag na kaalaman at kasanayan sa mga miyembro ng CIA upang magkaroon sila ng alternatibong mapagkakakitaan. Sa isinagawang training, natutunan ng mga participants ang wastong pagproseso ng ibaโ€™t ibang produktong gawa sa karne tulad ng longganisa, siomai, at embotido gamit ang karne ng baboy, manok, at baka. Naging makabuluhan din ang hands-on activities upang higit nilang mahasa ang kanilang kakayahan sa meat processing.

Sa pamamagitan ng mga ganitong programa, patuloy na ipinapakita ng NIA MARIIS ang suporta nito hindi lamang sa pagpapalakas ng irigasyon kundi maging sa pagpapabuti ng kabuhayan ng mga irrigators at kanilang pamilya. Inaasahan na ang mga natutunang kasanayan mula sa training ay magsisilbing dagdag oportunidad para sa mas matatag at maunlad na pamumuhay ng mga miyembro

The National Irrigation Administration โ€“ Magat River Integrated Irrigation System, Dam and Reservoir Division (NIA-MARIIS DRD) plays a vital role in the operation and maintenance of Magat Dam. The Flood Forecasting and Instrumentation Section (FFIS), through its advanced Command Center, is responsible for the real-time monitoring of hydrological data, telemetry and instrumentation equipment, communications, and the efficient delivery of the Irrigation Diversion Requirement (IDR).

Through a network of telemetered rainfall and water-level gauges, warning stations, and dam instrumentation, these systems are monitored remotely 24/7 and properly maintained to ensure the integrity of Magat Dam, efficient water management, and the safety of downstream communities along the Magat River.

During extreme weather conditions, the FFIS Command Center, in close coordination with the Department of Science and Technology โ€“ Philippine Atmospheric, Geophysical and Astronomical Services Administration (DOST-PAGASA), serves as the central hub for rainfall forecasting, communication dissemination, and dam operations. These functions are essential for faster information sharing, increased awareness, and timely responses among downstream stakeholders.
