Zamboanga Peninsula is one of the regions piloted by the  National Nutrition Council in scaling up the Local Nutrition Early Warning System (LNEWS-FNS). To date the region has a total of four municipalities where  the LNEWS-FNS is in placed and data generated being utilized by the LGUUs for planning purposes. At one area per year since 2014, the municipalities with functional LNEWS-FNS are   Polanco, ZDN, Diplahan, ZSP, Kumalarang, ZDS and Jose Dalman, ZDN.  

The LNEWS-FNS is a surveillance system that aims to build capacities of the local officials and workers in collecting , analyzing , reporting and utilizing food security and nutrition data for evidence - based decision making and program planning. Implementation of the system  has generated various practical experiences  among LGUs. To mention a few these are the following: 1) high level of acceptance by the LGU to the program, 2) Active involvement and cooperation of the data collectors and the sentinel barangays, and 3) result of the survey was used in planning.

With the LNEWS-FNS in the four municipalities functioning at various degree of implementation, a joint  Program Implementation Review (PIR ) was facilitated by the  National Nutrition Council Regional Office 09 on November 14-15, 2017  at Hotel Guillermo in Pagadian City.  Attended by the municipal Core Groups and Sentinel Barangay Data Collectors, the PIR which aimed to assess the implementation  of the system was an opportunity to draw information and lessons that can be used to further refine the program. The review focused specifically on how the data  collection, analysis, reporting and utilization were carried out. The municipalities of Polanco and Diplahan being the eldest among the four municipalities  in the LNEWS-FNS contributed much of their experiences during the presentation of the results of the  1^st quarter to the 3^rd quarter survey and accomplishments in data analysis and usage.  The review facilitated the sharing of insights on facilitating and success factors, difficult and challenging  issues  encountered the implementers and lessons and recommendations were drawn from them to enhance and make the system more functional in the region.
