Climate changes that affect our planet nowadays, will lead us to approach to what is happening with the mountain glacial of our country, characterized by its fragility. The Cordillera Blanca is one of the most important glacial areas of our country. Most of the monitoring activities have been carried out on the field where many times a lot of obstacles to collect information are found. In this way, Geomatics, by means of Remote Sensing, helps us to conduct with greater ease the monitoring tasks, using satellite images to determine the melting area of the glaciers. For the study, political boundaries of Huaraz and Independencia districts, as well as the use of several satellite images of 1989, 1998 and 2005 have been considered as references, which help us analyse the behaviour of glacial regression in a period of 16 years and forecast such behaviour by 25 years (2014).

The Agro-Ecological Zonation (ZAE) defines areas based on soil, physiography and climatic characteristic combinations (FAO, 1997). To do this, the Geographic Information Systems (GIS) by using the Help Systems for Spatial Decision (SADE) are a tool of fundamental importance in topics related to the agrarian development. This allows us to manage the variables of the physical environment where this activity is made, such as the climate, soil, and water; each one is characterized by the spatial variation of the territory. Climate is mainly influenced by the place topography; soil is considered as a potential resource but also as a hindrance to the cultigens’ growth; water is considered as one of the main shortages for the Tacna Region, and its influence on crops is analyzed according to its availability and quality. All these variables should be spatialized within the study area to integr...

La presente investigación centra sus aportes en el estudio de los niveles de peligro de origen natural como aluviones e inundaciones que amenazan a los elementos esenciales localizados en la ciudad de Huaraz (puentes y recintos como hospitales, colegios, bomberos) y áreas de expansión (puentes, carreteras y el aeropuerto de Anta). Esos elementos son considerados esenciales porque tienen que ver con el normal desarrollo del área urbana. El área de estudio no es ajena a esta situación, ya que históricamente se ha visto afectada por el impacto de eventos geológico-geomorfológicos, tales como aluviones e inundaciones. Es decir, desastres constituidos por cuantiosos daños materiales y la pérdida de vidas humanas, que cambiaron la configuración territorial. La ciudad de Huaraz fue reconstruida en gran parte, sin embargo, en la actualidad viene creciendo en zonas de peligro muy alto...
