Agroecological zoning of the municipal district of Lagoa Seca, Paraíba State

This work sought to perfect zoning which concerns the agricultural, ecological and social aspects in the municipality of Lagoa Seca in the State of Paraíba through the study of several scenarios in that area. It consisted of a set of approaches such as photo interpretation, geo-referenced image processing, and satellite positioning associated with Bertrand's Systemic Theory that allowed the identification, delimitation and analysis of areas of anthropic and agricultural usage as well as of those with remaining significant vegetation, which characterize the municipality. Digital geo-referenced files were elaborated for the studied area comprising basic data about the municipal limit, urbanized areas, road systems, drainage system, altimetry, cover of natural vegetation, soil farming usage and zoning of agroecological regions. The study showed that the municipality of Lagoa Seca has four regions with distinct aspects, as agroecological regions which were identified according to the factors prevailing in each area.
