“…In the same sense, the use of sensors in cities provide information from the Earth's surface and existing covers: the detection of the urban structure, analysis of urban sprawl, general mapping, mapping of transport networks, mapping of urban trees, etc. (Cardozo and Da Silva 2013). This process generates an image where a portion of the earth's surface is represented by the smallest unit of information (pixel).…”

The integration of rooftop greenhouses (RTGs) in urban buildings is a practice that is becoming increasingly important in the world for their contribution to food security and sustainable development. However, the supply of tools and procedures to facilitate their implementation at the city scale is limited and laborious. This work aims to develop a specific and automated methodology for identifying the feasibility of implementation of rooftop greenhouses in non-residential urban areas, using airborne sensors. The use of Light Detection and Ranging (LIDAR) and Long Wave Infrared (LWIR) data and the Leica ALS50-II and TASI-600 sensors allow for the identification of some building roof parameters (area, slope, materials, and solar radiation) to determine the potential for constructing a RTG. This development represents an improvement in time and accuracy with respect to previous methodology, where all the relevant information must be acquired manually. The methodology has been applied and validated in a case study corresponding to a non-residential urban area in the industrial municipality of Rubí, Barcelona (Spain). Based on this practical application, an area of 36,312m out of a total area of 1,243,540m of roofs with ideal characteristics for the construction of RTGs was identified. This area can produce approximately 600tons of tomatoes per year, which represents the average yearly consumption for about 50% of Rubí total population. The use of this methodology also facilitates the decision making process in urban agriculture, allowing a quick identification of optimal surfaces for the future implementation of urban agriculture in housing. It also opens new avenues for the use of airborne technology in environmental topics in cities.

“…The characterization of land use and land cover is an essential aspect in the analysis of the quality of environments, as it enables you to assess the state of the land and analyze the subsequent impacts on it (Posada and Salvatierra 2016;Avilés-Ramírez et al 2017;Sepúlveda-Varas et al 2019). Remote sensing provides images with information for a large number of applications such as land use mapping, urban planning, environmental monitoring and crop management (Cardozo and Da Silva 2013). Satellite images are digitally generated through an electromagnetic interaction that occurs between the satellite and objects on the Earth's surface (Chuvieco 2015).…”

“…The Landsat 8 satellite has a sun-synchronous, near-polar orbit system with an altitude of 705 km, which ensures full coverage of the Earth's surface and the same solar illumination conditions for all of the areas observed (USGS 2021). The objects present in a satellite image are characterized through various picto-morphological criteria (Cardozo and Da Silva 2013). Remote sensing and Geographic Information Systems (GIS) are used in environmental studies as a tool for monitoring animals, detecting changes in vegetation cover, and creating land use maps, amongst other such studies.…”

The study of biomarkers in free-living birds can help indicate the degree of contamination in distinct environments. In addition, these environments can be characterized through the information provided by satellite images. The objectives of the present study were to analyze the types and quantity of cytogenetic biomarkers in Passer domesticus (sparrow) from three different environments; wild, rural and urban; and to analyze them in the context of land use and anthropogenic actions. Five thousand erythrocytes per bird were analyzed for the following nuclear alterations (NA): micronuclei (MN), nuclear buds, notched nuclei, binucleated cells, nucleoplasmic bridges, nuclear tails, peripheral nuclei and enucleated cells. In the study, wild birds exhibited five types of NA, seven types were found in rural birds; and all types were encountered in urban birds. The only NA that exceeded a frequency of 2 NA/ 1000 erythrocytes were peripheral nuclei in birds from the rural and urban sites, the latter environment characterized by 87% urban soil and air pollution. The highest frequencies of MN, peripheral nuclei and enucleated erythrocytes were recorded in sparrows from the rural site (p≤0.05).This area had been sprayed with chlorpyrifos 48%, the most widely used organophosphate in the region. Sparrows from the wild site, made up of 100% native forest, had higher frequencies of notched nuclei (p≤0.05). A precedent is set for the use of environmental remote sensing in a complementary manner with cytogenetic biomarker studies in birds for a joint analysis in environmental assessment.
