Abstract

The Net Primary Productivity (NPP) is the fundamental process in the biosphere functioning and is needed for assessing the carbon balance at regional and global scale. NPP in many forest ecosystems have experiencing many changes due to anthropogenic activities. Many research and studies have been carried out to monitor the pattern and distribution of NPP, and various models have been developed. The main objective of this study is to carry out an analysis of NPP of tropical forest using three different types of satellite data; (i) NOAA AVHRR, (ii) MODIS, and (iii) Landsat TM. The seasonal variation of NPP for forested area in Peninsular Malaysia were analalysed using NOAA and MODIS data while analysis of Landsat data was used to make a detail analysis of NPP for forested area in the state of Pahang. Results indicate that the highest value of NPP is for the month of April (301.65 g/cm2 month-1 followed by October (217.78 g/cm2 month-1, January (189.6 g/cm2 month-1) and July (89.22 g/cm2 month-1). NPP maps showing seasonal pattern of NPP were also produced using Geographical Information System (GIS)
