Between September 28th and October 1th, 2015, Jhon Tello from Terra-i team, participated in the fieldwork in the department of Puno, Peru, organized by the Directorate General of Land Management DGOT - MINAM.

Fieldwork team

The field activities were directed by Germán Marchand, Witman Garcia and Angelica Sauñe, specialists from the Directorate General of Land Management DGOT - MINAM in coordination with the Regional Government of Puno - Regional Management of Natural Resources and Environmental Management - Project Planning territorial, specialists Yaneth De la Cruz Mamani y Yessica Quenta Gutiérrez, Perú. This work had as objective to perform activities of geographical reconnaissance and verification of results of changing land cover in the province of Sandia, districts of Alto Inambari and Phara, in the Puno department, as well as areas of Puno, Juliaca and Huancané. The specific objectives, focused on the verification of results of technological tools, which are based on visual and digital interpretation of satellite images. These are used to analyze changes in land cover as its main contribution to the system of early detection and environmental monitoring of areas degraded by illegal and informal mining.

On the basis of a set of sampling points distributed over the work area and supported by the Protocolo de levantamiento de información de campo para reconocimiento y verificación cartografía sobre cambios en la cobertura de la tierra, developed by the DGOT - MINAM. The team visited points for recognition of illegal and informal mining activity related to changes of Terra-i, ClasLite and points of change based on visual interpretation. In each visited point a form field information was recorded with coordinates, height, photographs in the four cardinal points, class of use and coverage, among others. Additionally some points of interest associated with anthropogenic interventions were recorded during the journey.


The fieldwork was realized by land route. The points, which could be observed from the road, were primarily engaged in changes due to informal mining. The presence of dredgers and specialized machinery dedicated to mining was quite evident along the river Huari Huari, between the province of Sandia, Alto Inambari district and San Juan del Oro area. In points located between San Juan del Oro and the District of San Pedro de Putina Punco, crops such as coffee, cassava, citrus and coca were mainly found. In two points located in the district of Taraco province of Huancané alfalfa crops, forage oats and land in preparation for crops were identified.
These works are carried out under the policy framework endorsed by the Ministry of Environment of Peru and are part of the operational plans of the General Directorate of Land Management - DGOT.
The Terra-i team is grateful to the members of the General Directorate of Land Management - DGOT for the invitation to be part of this fieldwork. This experience is important to improve our knowledge in field validation and calibration of our system input.
