Introduction
I teach at the Facultad de Ingenieria Agricola. Current research includes the application of GIS, remote sensing, and spectroscopy for soil and vegetation analysis. I promote the use of free software for data analysis, text preparation and publications. I work with enthusiasm; I adapt to collaborative work and to the use of new technologies.

Forests are key ecosystems for climate change mitigation, playing a pivotal role in C and N land sequestering and storage. However, the sustainable management of forests is challenging for foresters who need continuous and reliable information on the status of soil conditions. However, the monitoring of soils in temperate evergreen forests, via sat...

This climatic variability affects erosion patterns. An important aspect prior to the calculation of erosion is Erosivity. In the present work the objective is to undertake a spatial estimation of Erosivity in Manabí province with the CORINE method. This method calculates Erosivity by integrating two climatic indices: the Modified Fournier Index (MF...

Soil organic carbon (SOC) is an important indicator of soil quality; an elevated percentage of SOC indicates very high-quality soil, physically as well as chemically. As such, the principal objective of the present study was to determine the concentration of SOC at different depths, as well as its accumulation through the entire soil profile. The C...

Most of the basins in the Central Valley region of Cochabamba (Bolivia) show soil erosion, scarce vegetation cover, and periods of intense and short rainfall that occasionally generate violent river floods from runoff that, as a direct consequence, produce disasters that affect the urban and rural infrastructure. The objective of the present wor...

Soil spectroscopy is known as a rapid and cost-effective method for predicting soil properties from spectral data. The objective of this work was to build a statistical model to predict soil carbon content from spectral data by partial least squares regression using a limited number of soil samples. Soil samples were collected from two soil orders...

The province of Manabi is one of the main farming areas of Ecuador, and it has seen an increase in land use in response to the demand for food. Unfortunately, this area growth has brought problems such as inadequate field planting techniques and forest destruction. Alternative techniques or processes to improve productivity in the medium and long t...
