The Brazilian semiarid region (BSR) has faced severe drought over the last three decades, which has led to a significant decline in land productivity, posing a considerable threat to food security and the local economy and communities. The United Nations Convention to Combat Desertification (UNCCD) has proposed the use of Earth observation-derived...
One of the core challenges to achieve Land Degradation Neutrality (LDN) is to spatially identify, and strategically prioritise, the areas to implement actions to avoid, reduce and reverse land degradation. To achieve this, a tool for a participatory and data‐driven assessment considering both the biophysical, and socio‐economic dimensions of land d...

Conocer las coberturas de suelo es clave para el manejo, conservación y gestión de
socioecosistemas a distintas escalas. El uso de sensores remotos es una herramienta útil en su identificacion, presentando desafíos en regiones boscosas, para la distinción entre tipos de leñosas. El análisis de imágenes radar y series temporales de índices espectral...
Reliable spatial data of evapotranspiration (ET) in support of water resources management are limited. ET is a major component of the water balance, in many regions, and therefore it is critical that it be accurately quantified. To identify a product that accurately estimates spatially distributed ET for application in data-scarce regions, an inter...

Monitoring progress towards the 2030 Development Agenda requires the combination of traditional and new data sources in innovative workflows to maximize the generation of relevant information. We present the results of a participatory and data-driven land degradation assessment process at a national scale, which includes use of earth observation (E...

ABSTRACT:
In this work, forecasts of monthly mean flows were made using the NMME tool (North American Multi - Model Ensemble). NMME is a seasonal multi-model experimental forecasting system that consists of coupled models of different modeling centers (such as NOAA / NCEP, NOAA / GFDL, IRI, NCAR, NASA and CMC of Canada). This work is being done and...
As part of the Sustainable Development Goals, countries are striving to achieve by 2030 a land degradation neutral world. Land degradation neutrality (LDN) is the state whereby the amount and quality of land resources remains stable or increases within specified temporal and spatial scales. Achieving this will require the uptake of sustainable land...
The Puna region, located in NW Argentina, is a dry highland with many endemic species and significant traditional cultural heritage. The Puna was a pilot region for the Land Degradation Assessment in Drylands project (LADA-FAO) which aimed at assessing desertification status in different land use systems (LUS). The results of these assessments are...
p>Los modelos de pronóstico hidrológico son herramientas matemáticas que se emplean mientras se está produciendo una tormenta con el fin de predecir el caudal que se producirá en una sección de un río con un cierto tiempo de anticipación (horizonte de pronóstico). Como información de entrada suelen utilizar la lluvia y el caudal de la sección de in...

La cuenca del río San Antonio es una de las más importantes en la Provincia de Córdoba, ya que desempeña múltiples funciones: turismo, riego y provisión de agua para potabilizar a algunas ciudades importantes como Carlos Paz. A raíz de los vertiginosos crecimientos poblacionales registrados en esta región serrana, esta cuenca de clima semi-árido ad...
Satellite-based remote sensing of soil water content (SWC) is a promising technology for hydrological applications to overcome large spatiotemporal variabilities of SWC. This study investigated the performance of the Advanced Scatterometer (ASCAT) soil moisture product on METOP satellite (∼12.5 km and downscaled to ∼1 km resolution), against ground...
Quantification of the water cycle components is key to managing water resources. Remote sensing techniques and products have recently been developed for the estimation of water balance variables. The objective of this study was to test the reliability of LandSAF (Land Surface Analyses Satellite Applications Facility) evapotranspiration (ET) and SPO...
Este trabajo presenta una evaluación experimental de una técnica de cuantificación de caudales de aguas superficiales en ríos serranos de la provincia de Córdoba. Los ríos serranos de la provincia de Córdoba se caracterizan por su alta variabilidad temporal definida por la ocurrencia de crecientes repentinas o torrenciales de corta duración y gran...

Los Sistemas de Información Geográfica (SIG) y la disponibilidad de imágenes satelitales proveen una fuente de información que ha permitido el desarrollo de numerosos estudios de la distribución de especies y su relación con variables ambientales. La escala a la que se analiza el fenómeno de interés no es trivial y muchas veces no es claro cuál es...
El proyecto sobre la Evaluación de la Degradación de las Tierras Secas (LADA) busca establecer las bases conceptuales y poner en marcha una metodología de fácil manejo y comprensión para evaluar y realizar mapas de la degradación de la tierra que aceleran los procesos de desertificación. Las evaluaciones del proyecto LADA se realizan en tres escala...
In the face of climate change and for sustainable management of arid areas, it is crucial to understand the link between water availability and vegetation growth. This linkage is often investigated using time series of rainfall data and vegetation indexes from satellite sensors (e.g. NDVI). However, rainfall alone is not sufficient to describe avai...
Effects of livestock exclusion on plant diversity and vegetation structure have been well studied in the Córdoba Mountains. Exclusion has both positive and negative effects for conservation, depending on time-scale and the underlying conservation objective. Short-term ( 20 years) livestock exclusion do not exist, but it is likely that this would be...
RESUMEN: El manejo integrado de cuencas hidrológicas tiene importancia económica y social, especialmente en Argentina, donde el 70% de la superficie corresponde a zonas áridas y semiáridas. En Córdoba, el crecimiento poblacional junto al comienzo de una temporada de sequías, han puesto en emergencia hídrica a la población. Los modelos hidrológicos...
