Evaluation Of Land-use Practices In The Upper Pastaza River Basin Related To Flow Regime And Sediment Load Characteristics
Abstract
This Master’s Degree project (MDP) provides an evaluation of the current situation and land use practices in the upper Pastaza river basin, and relates these practices to the erosion and sediment production in the area, which constitutes a problem that influences the Agoyan hydro power plant performance. In this work, suggestions for land use best practices and basin management are provided as an aim to contribute to the erosion minimization and productivity (agricultural and electric) enhancement in the upper Pastaza river basin, seeking also the improvement in the quality of life of local inhabitants. The analysis of the agricultural practices in the upper Pastaza river Bain showed that they influence on soil erosion and sediment production. Monocultivation, deforestation, paramo clearing – together with population growth and urbanization – are main factors promoting soil erosion, sediment production and land infertility in the basin. A research of best agricultural practices to minimize erosion and enhance land productivity was done for this work. Some recommended best practices mentioned in this project are crop rotation, contour cultivation, crops residues, terraces, grass water ways use, among other techniques presented that have given good results for combating erosion problems.
