A strategy to measure the overall impact of the NGP overtime was developed by ERDB scientists and first tested in a 350-hectare NGP planting site in Siniloan, Laguna in 2013. Its application has been expanded to 79 planting sites where baseline data on biological, physical, spatial, and socio-economic components were examined prior to NGP tree planting activities. Baseline data will be compared with the data to be gathered in 2016 and beyond using appropriate scientific analysis to determine the NGP impact.
The main purpose of biological baselining/benchmarking is to assess the composition of the NGP site prior to the introduction of tree planting activities in terms of its biological status using indices of diversity evenness, dominance, and community coefficient.
PHYSICAL COMPONENT (SOIL AND WATER RESOURCES)
This component focuses on using the physical features in assessing the stability, nutrient cycling, and hydrological function status of the landscape where NGP activities will be implemented
This component aims to assess the existing socio-economic condition of the target NGP beneficiaries prior to the implementation of the program. Baseline information on the social conditions, economic characteristics, and awareness on NGP shall be gathered through face-to-face interviews with an aide of an interview schedule.
This component describes the procedures for making GIS-based maps and other spatial information necessary to support the baselining activity for the NGP site. Its main objective is to produce maps and generate spatial information necessary to support the baseline characterization of biological, physical, and socio-economic conditions of an NGP site.
