In this paper, a multifractal downscaling technique is applied to adequately transformed and lag corrected normalized difference vegetation index (NDVI) in order to obtain daily estimates of rainfall in an area of the Peruvian Andean high plateau. This downscaling procedure is temporal in nature ...

Multifractal downscaling of rainfall using Normalized Difference Vegetation Index (NDVI) in the Andes Plateau.
La maca (Lepidium meyenii) es una raíz andina a la cual se le atribuyen propiedades energéticas y estimulantes. En los últimos años el interés de mercados asiáticos dio lugar al “boom de la maca”, incrementando los precios y provocando la rápida conversión de pastizales altoandinos en tierras de ...

Downscaling techniques aim at resolving the scale discrepancy between climate change scenarios and the resolution demanded for impact assessments. Requirements for downscaled climate, to be useful for end users, include reliable representation of precipitation intensities, temporal and spatial va...

Application of non-linear techniques for daily weather data reconstruction and downscaling coarse climate data for local predictions
Agricultural UAV-based remote sensing tools to facilitate decision-making for increasing productivity in developing countries were developed and tested. Specifically, a high-quality multispectral sensor and sophisticated-yet-user-friendly data processing techniques (software) under an open-access...

Development of low-cost remote sensing tools and methods for supporting smallholder agriculture.
Remotely sensed data are often used as proxies for indirect precipitation measures over data-scarce and complex-terrain areas such as the Peruvian Andes. Although this information might be appropriate for some research requirements, the extent at which local sites could be related to such informa...

Retos para la produccion sostenible de papas en un clima cambiante: Una perspectiva de investigacion.
Potato production systems face constant changes in climate conditions and the projections for the future indicate that changes in temperature and precipitation are expected in certain regions of the world. The impact will depend on what we do today to avoid negative consequences. Climate projecti...
