Frequent and recursive floods and droughts have been resulting serious food shortage in North Korea so that the agricultural land consolidation is required to provide secure crop production basis. Water resources development is a key factor for the agricultural land consolidation and agricultural water demand has to be estimated, thus the estimation of the agricultural water demand of paddy fields in North Korea is necessary. However, due to the lack of available data in North Korea, it requires to apply the developed methods in this study to South Korea firstly and examine the suitability of using them in North Korea. First of all, a study area which has the topographical feature to North Korea’s was determined in north part of South Korea and GIS data, meteorological data of Korea Peninsula and MODIS images were synthesized for extracting paddy fields. In addition, the FAO Blaney-Criddle method and 10-day crop coefficients of the northern areas of South Korea were used in order to estimate consumptive use of water in paddy fields. The objective of this study is to assess the appropriateness of the results through comparing to reference data and apply for estimating agricultural water demand in North Korea.(Download PDF) (Export to EndNotes)
