En el presente artículo se invita a discutir el marco conceptual y metodológico de un indicador de bienestar multidimensional, que incluye una dimensión de uso del tiempo junto con dimensiones de condiciones de vida usualmente incorporadas en este tipo de análisis. Las carencias identificadas mediante los componentes de este indicador se entienden como un obstáculo para el desarrollo de las capacidades humanas. El objetivo último es mirar más allá de las métricas monetarias e identificar los indicadores que mejor explican cómo la población, en lugar de las economías, se está desarrollando. En este análisis se emplea la metodología de identificación y agregación de Alkire y Foster (2007 y 2013) y se muestran los resultados para cuatro países de la región (Colombia, Ecuador, México y Uruguay) utilizando encuestas sobre el uso del tiempo y distinguiendo, además, por tipo de hogar.

La Clasificación de Actividades de Uso del Tiempo para América Latina y el Caribe (CAUTAL) es el resultado de una larga trayectoria de trabajo del Grupo de Trabajo sobre Estadísticas de Género de la Conferencia de Estadística de las Américas (CEA) que responde a la necesidad de los países de América Latina y el Caribe de contar con un instrumento con enfoque de género y adecuado al contexto regional, que permita la armonización y estandarización de las encuestas de uso del tiempo, así como la producción de estadísticas en esta temática. Las actividades cotidianas y los tiempos que las personas les dedican, se enmarcan en un contexto definido por factores de género, sociales, económicos, culturales y del marco jurídico e institucional. La CAUTAL ofrece la posibilidad de disponer de una visión integral y ordenada de las actividades que las personas realizan y del tiempo que les dedican. Así, permite visibilizar las diferentes asignaciones de tiempo de mujeres y de hombres, aportando insumos y evidencias para las políticas públicas de igualdad en los ámbitos social y económico.

The misuse of land by man and is causing serious problems to the environment, resulting in ecological imbalance and depletion of natural resources, especially when it comes to areas of permanent preservation, that ecosystems are essential for balance and water conservation importance . Conflicts of land use is a major cause of silting of rivers and water bodies, causing significant losses in soil and decaying natural water resources both in quantity and in quality. Within this scenario, the planning becomes essential for the control of environmental impacts to the environment factor. This study aimed to evaluate land use conflicts in permanent preservation areas of the stream Água Fria watershed, Bofete (SP) using Geographic Information System and satellite image of LANDSAT - 5 of 2010, scale 1:50000. The results show that 51.16% of the permanent preservation areas of the watershed are conflicting, especially for pasture (88.94%) and reforestation with eucalyptus (11.06%). The GIS IDRISI Selva and Cartalinx along with GIS techniques demonstrated speed and efficiency in identifying, measuring and editing maps of land use, preservation and ongoing conflicts in areas of permanent preservation.

The study aimed to obtain the land use of the watershed Stream São Caetano - Botucatu (SP), through the satellite image. The cartographic databases were: planialtimetric letter in digital format (IBGE) used in georeferencing, and satellite image. Geographic Information Systems (GIS) -IDRISI Selva was use to perform the image georeferencing and to do the final thematic map. In the software CAD - CartaLinx, it was performed the delimitation of the area under study (boundary, drainage network and areas of use and coverage). The land use of the watershed showed that pasture was the class which occupied most of the area, with 34.51% (1117,94 ha), the remainder of the area was urban (692,19ha), forests (809,79ha), cultures (599,96ha) and a very small part of reforestation (19,53ha). The use of remote sensing and geoprocessing were very satisfactory in the present work. Technologies must be increasingly used in agricultural and environmental studies, because technological tools, such as Geographic Information System (GIS), present speed, efficiency, reliable results, helping in increasing sustainability

The study aimed to obtain the land use of the watershed Ribeirão Santo Antonio - São Manuel (SP), through the thematic map of the satellite image. The cartographic databases were planialtimetric letter in digital format used in georeferencing and the satellite image. Geographic Information Systems (GIS) -IDRISI Andes 15.0 was use to perform the image georeferencing and to do the thematic map obtained from the visual interpretation the satellite image. The map of land use showed that the culture of sugar cane occupies most of the area (81.00%), when analyzing the satellite image. This result show us the predominance of agricultural occupation in the region. The thematic map obtained by the classification screen, using GIS, allowed the mapping of land use, generating data that will assist in future planning area recovery. The results of the study showed the efficiency, speed and reliability of the tools used, these being very useful for future projects.
