Aplicação de técnica de sistema de informação geográfica - SIG para identificação de áreas potenciais para o cultivo de arroz em Moçambique

Abstract

The Mozambican Government's main concern is to seek sustainable solutions to meet the food needs of the population, using mostly domestic production and little dependence on imports. To respond to this concern, scientific research and subsequent dissemination of better production technologies and other extremely important information become fundamental and indispensable. This research work aims to apply the Geographic Information System technique to identify potentially suitable areas for rice cultivation in Mozambique. In order to achieve this objective, some rules of agricultural aptitude were taken into account, having as factors that influence the development of rice; the temperature, precipitation, elevation, texture and water holding capacity of the soil; the method of GIS logical operations called boolean was applied, which made it possible to perform intersections between two or more planes of spatial information. This crossing resulted in areas that gather favorable conditions for the production and development of rice established for all factors, having been noted that most of the same areas occurred close to riverside areas, coastal areas associated with flood plains, encompassing all regions of the country where they were A total of 10,008,365.16ha were obtained, of which 49% are located in the central zone, 33% in the south zone and 18% in the north zone (TRADUÇÃO NOSSA)
