In Brazil, coffee production has great economic and social importance. Despite this fact, there is still a shortage of information regarding its spatial distribution, crop management and environment. The aim of this study was to carry out spectral monitoring of coffee lands and to characterize their environments using geotechnologies. Coffee fields with contiguous areas over 0.01 km2 within a 488.5 km2 region in the south of Minas Gerais state were selected for the study. Spectral data from the sensors OLI/Landsat 8 and the Shuttle Radar Topography Mission from 2014 to 2015 were obtained, as well as information on production areas, surface temperature, vegetation indexes, altitude and slope, were gathered and analyzed. The results indicate that there is great variation in the NDVI and NDWI values, with means ranging from 0.21 to 0.91 (NDVI) and 0.108 to 0.543 (NDWI). The altitude ranged from 803 to 1150 m, and the surface temperature from 20.9°C to 27.6°C. The altitude and the surface temperature distribution patterns were correlated with the vegetation indexes. The slope classes were very homogeneous, predominantly with declivities between 8 to 20%, characterized as wavy relief. This study made possible the characterization and monitoring of coffee lands and its results may be instrumental in decision-making processes related to coffee management. |

Los indicadores de sustentabilidad son herramientas de fácil utilización por los agricultores y técnicos involucrados en el desarrollo rural. Así, ese trabajo tuvo por objetivo utilizar los indicadores de sustentabilidad cómo forma de discutir técnicas de manejo más sostenibles para la producción de hortalizas entre campesinos en Distrito Federal, Brasil. Por lo tanto, fueron utilizadas como herramientas los indicadores de sustentabilidad y las prácticas de uso de abonos verdes como estrategia para la diversificación. El uso de los indicadores en las unidades posibilitó identificar diferentes niveles de conservación y usos de recursos en los sistemas productivos. Fue posible introducir nuevas técnicas, como el uso de los abonos verdes y conceptos, como el de transición agroecológica y estrategias de conservación y diversificación que llevan al rediseño de la propiedad. Los agricultores reconocen la necesidad de cambio del sistema productivo actual para un modo más sostenible.
Abstract: The sustainability indicators are good tools for easy use by farmers and technicians involved in rural development. Thus, this study aimed to use these indicators as a way to discuss more sustainable techniques for vegetable production among farmers in Distrito Federal, Brazil. Therefore, were used the indicators of sustainability and practices of green manuring as a strategy for diversification. The use of indicators in these units enabled to identify different levels of conservation and resources use in that production systems. It was possible to introduce new techniques such as the use of green manure and concepts, such as agro-ecological transition and conservation strategies and diversification that leads to the redesign of these properties. Farmers recognize the need to change the current production system to a more sustainable way.
