Four Pillars of digital land resource mapping to address information and capacity shortages in developing countries

摘要

Like many developing countries, the Philippines has a shortage of land resource information at sufficiently fine scales for effective land-use planning. The country is also short of capacity to acquire such information with a declining number of soil surveyors and limited capability and resourcing of soil analytical laboratories. Digital land resource mapping (DLRM) provides an opportunity to address these shortages. A project in the Cabulig watershed (220 km(2)) of Northern Mindanao developed operational protocols by combining existing technologies to form a DLRM framework based on four 'pillars'.
