The Lalog 1 Site 1 Solar Pump Irrigation Project (SPIP), implemented by NIA-MARIIS through its Division IV in Barangay Lalog 1, Luna, Isabela, covers 15 hectares and benefits 20 farmer beneficiaries.

Before the project, farmers in the area primarily planted corn. With the additional water from the Lalog 1 Site 1 SPIP, the area can now support rice production during the primary cropping season, followed by double-dry cropping with mungbean after harvest. This allows farmers to maximize their land, increase farm productivity, and create opportunities for additional income.

Patuloy ang ng mga kawani ng NIA-MARIIS sa Division I sa pakikipag-ugnayan sa Municipal Agriculture Office (MAO) ng Echague, Isabela para sa harmonized updating ng Registry System for Basic Sectors in Agriculture (RSBSA).

Kasabay nito, isinasagawa rin ang pamamahagi ng binhi (seed distribution) para sa mga kwalipikadong magsasaka, bilang bahagi ng sama-samang pagsisikap na matiyak na ang tulong at serbisyo ay wasto, maayos, at napupunta sa mga tunay na benepisyaryo.
Sa pamamagitan ng koordinasyon at pagtutulungan ng mga ahensya, mas napapalakas ang paghahatid ng serbisyo tungo sa mas produktibo at mas matatag na sektor ng agrikultura.

Sama-sama para sa magsasaka. Sama-sama para sa mas maunlad na agrikultura!
