Caracterização socioeconómica e físico-hídrica de áreas irrigadas no baixo piancó, Pombal-PB.

Abstract

Although Brazil occupies a privileged position in relation hydra availability, this badly is distributed, being the devoid half-barren region of this resource, observing itself in the use of the irrigation, one of the forms to keep the production in the region, however, must be taken in consideration the sustainable use of the water, for being this an limited good. Ahead of this. it was objectified, with this work, to characterize the áreas irrigated situated in Piancó River, stretch Pombal, how much to the systems of irrigation, agriculturas production and ground, for in such a way, was carried through a survey in the áreas understood between ' coordinates 6' 57' 37.53'' to 6' 48' 14.49'' S e 37' 55' 17,15'' a 37o 49' 10,31'' w, arising the social characteristics of the irrigates farmers, the characteristics of the production systems, both with questionnaire use, beyond the survey of some characteristics physicist-hydra, as porosity and speed of inülltration basic of the ground. Being able itself to verify low index of study of the farmersl a used degree of technology in the irrigation is average, however the agriculturists little are enabledl the main method of used irrigation is the conventional, with bigger participation of the system of irrigation for aspersion with use of the hydraulically cannon and the speed of infiltration of ground can be classified as average. Sending regards to promote qualiülcation of the agriculturists in irrigation, acquiring knowledge them on the preservation of the environment and the efficient use of the water, being interesting that new projects of irrigation contemplate the method of located irrigation, allowing bigger efficiency in the application beyond lesser ambient impact, for promoting minor risk of erosion to the ground.
