SOCIOECONOMIC DYNAMICS, THE USE OF MULTI-MASTER-SPACE SOIL AND ITS ENVIRONMENTAL IMPACT ON THE WATER RESOURCES OF THE MICROCUENCA OF THE RIO BILAMPÍ, MUNICIPALITY OF RÍO BLANCO, DEPARTMENT MATAGALPA, NICARAGUA, I SEMESTER 2013

Abstract

The research was conduted in the municipality of Rio Blanco, Matagalpa at coordinates UTM north 1437714 y 690735 west, to assess the socicioeconomic diynamics census was applied to 70 families distrubuted in the wastershed, all dedicated to extensive agriculture and low levels of technoly that currently influence in the deterioration of soil and water resources.
 On the basis of land mapping produced by INETER (year 2006) were georeferenced productive areas (farm) located in the upper, middle and lower yielding the study área map of current land use in 2013, then in the multitemporal analysis of land use covarage (latifoliado forest and agricultural land) according to the years 1983, 1990, 2001, 2006, we detected and Exchange rate of 450 ha of broadleaf forwst were replaced by agricultural land.

Map of current use and potential use was indentified tha the area has and index of 40 % overused land proper use underutilized 39% and 21%, indicates that the first data is being exploited above potential established (forest).

To assess the environmental impacts on water resources environmental implications analyzed and applied another instrument that involves taking a simple of water in the bottom of the watershed, it was transmitted CIRA-UNAN to be subjeted to analysis organochlorine and orgaphosphorus pesticide type.
