A quantitative land evaluation of agricultural productivity potential and the corresponding population supporting capacity involved a compilation of an appropriate climatic resource inventory. This paper aimed to present a climatic inventory of the Philippines to describe prevailing moisture and temperature regions. The concepts of the length of growing period was used to define the moisture regions. Historical records were used to determine the length of growing and its variabilities. Temperature regimes were based on near daily temperature during growing periods and or theoretical temperature-altitude relationships, when these observed data are not available. Modifications could be done to have a more realistic climatic inventory. Water balance could be done on a shorter period, such as a decadal basis so that the occurrence of short duration water shortages will not be obscured. Soil type could be used also to determine the water holding capacity.
