Ngayong umaga, inilahad ni NIA Administrator Engr. Eddie G. Guillen na ang tunay na paglilingkod ay nasusukat sa lawak ng pagbabago sa buhay ng ating pinaglilingkuran โ€“ ang mga magsasaka.

Bawat magsasakang naalalayan, bawat ektaryang napapatubigan, at bawat proyektong naihahatid ay patunay ng ating malasakit sa bayan. Sa diwa ng kanyang mensahe, hinihikayat ang bawat kawani na manatiling masipag, masigasig, at bukas-palad sa serbisyo. Ang bawat araw sa NIA ay pagkakataong gumawa ng pagbabago at mag-iwan ng mabuting bakas para sa magandang bukas.

Before tractors, harvesters, and modern irrigation systems became part of agriculture, farming depended heavily on manual labor, simple tools, and the strength of carabaos in the fields.

For many farming communities in the MARIIS service area, preparing the land meant long hours of plowing with carabaos under the heat of the sun. Planting and harvesting were done entirely by hand, requiring patience, cooperation, and dedication from farmers and their families. Farming during those times was not only a livelihood โ€” it was a way of life deeply rooted in hard work and resilience.

As agricultural technology and irrigation systems developed over the years, farming practices gradually transformed, helping improve productivity, efficiency, and water accessibility for local farmers.

This , we honor the generations of farmers whose perseverance laid the foundation for the progress of agriculture today.

Sa mensahe ni NIA Administrator Engr. Eddie G. Guillen, malinaw ang hangarin na gawing bukal ng pag-asa ang bawat patubig na naihahatid sa bukirin. Ang irigasyon ay serbisyong may direktang epekto sa buhay at pag-unlad ng mga pamilyang umaasa sa agrikultura.

Sa pagpapatuloy ng mga programang nakatuon sa pagpapalakas ng kanayunan, mas nabibigyan ng pagkakataon ang mga magsasaka na umangat at makapagsimula ng mas maayos na kinabukasan. Ito ang diwang patuloy na isinasabuhay ng NIA para sa buong bayan.

Bahagi ng paghahanda ng NIA para sa epekto ng El Niรฑo ang mas pinatibay na suporta sa ating mga magsasaka mula sa paggamit ng datos at koordinasyon hanggang sa pagpapaunlad ng kabuhayan at pagpapatupad ng climate smart agricultural projects.

Tinututukan ng NIA ang mga hakbang na magpapatatag sa ani, kita at kabuhayan ng bawat magsasaka lalo na sa panahon ng tagtuyot.

Tuloy ang daloy, ani at kabuhayan dahil sa ating kahandaan.
