LAND DEGRADATION AND SOIL CONSERVATION WITHIN THE SIMILA CATCHMENT –TUTOVA ROLLING HILLS
Journal Title: Present Environment and Sustainable Development - Year 2012, Vol 6, Issue 2
Abstract
The Simila catchment is located in the Tutova Rolling Hills, Southern Moldavian Plateau, and covers 252.83 km2. The sandy - clayey Miocene-Pliocene layers have been modeled by the local geomorphological factors as a series of parallel prolonged hills which typify the entire area. The improper human activity, mainly deforestation, up and down hill farming and inadequate road network resulted in significant land degradation through the development of sheet erosion, gullying and less through landslides. The overall estimation shows that sheet erosion produces 12.02 t ha-1yr-1 (276500 t yr-1), that represents 56 % of the total erosion within the Simila basin. On the other hand, the value of gully erosion rate is estimated at 7.4 t ha-1yr-1(186075.5 t yr-1). Therefore, total erosion is averaging 19.38 t ha-1yr-1(462,836.9 t yr-1) and proves the advanced state of degradation that characterizes especially the agricultural lands in the research area. A map of the appropriate conservation practices for the suitable usage of the cropland within the Bogdăniţa catchment was drafted. The major changes are as follows: the arable reduces to 575 ha, only under strip-cropping system; the quality of the pastures must be improved; the forestland extends from only 232 ha (18% of the entire area) to 507 ha (40%). All unproductive land must disappear.
