ABSTRACT

GEOTECHNOLOGIES
IN THE AGRICULTURAL INSURANCE OF THE SAFRINHA CORN Remote sensing images, global positioning systems (GPS) and geographic information systems (GIS) are the main geospatial technologies that can be applied to assist crop risk insurance. The objective of this work was to evaluate the use of these technologies in a sample of insured corn crop fields, during the fall-winter season of 2001, in the region of Assis, state of São Paulo. The corn fields were spatially located and the area was precise and quickly evaluated by using satellite image and/or GPS. Remote sensing images acquired during the corn growing season are useful to indicate crop growing conditions, to identify potential crop damage and to assist yield assessment, due to their spatial and temporal features. The GIS enables the spatial analysis and introduces an objective way to inspect crop fields, which is crucial in crop risk insurance activities. Key-words: remote sensing, crop insurance, monitoring, geographic information systems. JEL Classification: C42, G22, Q14. |
