Factores de degradação dos solos no posto administrativo de Namialo distrito de Meconta (1970-2000)

Abstract

Soil degradation is a dynamic process that consists of the loss of nutrients contained in the soil through degrading agents, or excess salinity. and soil acidification, Roose (1998). This phenomenon becomes strong in areas where vegetation is removed for the exercise of agricultural activities. In general, areas of high population concentration are more subject to greater pressure on soil resources. Normally, the destruction of natural vegetation has caused changes in the biological activity in the soil. Soil exposure to meteorological variations can make it vulnerable to erosive phenomena, thus accelerating its degradation. In rural areas such as Namialo, natural resources, namely: soil, water and forests are the basis for the survival of the population. The intensive use of natural resources, particularly soil, has led to its own degradation. Soil degradation in the administrative post of Namialo is a problem that affects the resident population and has concerned local authorities. This situation has conditioned low agricultural productivity, a fact that has negative implications for the socio - economic development of the population. The aim of this work is to study and analyze the factors of soil degradation in the administrative post of Namialo.
