Although currently Bogota has incipient measures and studies of UHI, it has been noticeable for the population that the temperature in the inner city has incresed. 10-15 years ago was common see fog and dew in the inner city; however, currently this foggy conditions just exist in the sourrounding of Bogota, known as Sabana de Bogotá. This is shown in the next image: ![Foggy condition outside Bogotá][1] Source: Twitter Rafael Colon-Freezing In the Sabana In contrast, the inner city present other type of conditions. The presence of fog is getting less present and smoke is more appreciable. ![Smoke in Bogota][2] Source: Www.google.com Photography taken by the Andes University. Looking for some studies on UHI in Bogota, It is mentioned that there are not clear diferentiation between which causes of city warming are due to the effects of climate change and effects by urbanization. However, I could find (in: "Estudio del Crecimiento Urbano con respecto al Efecto Isla de Calor para establecer Lineamientos de Gestión Energético Ambiental en Bogotá -2013 - Eleventh LACCEI Latin American and Caribbean Conference for Engineering and Technology (LACCEI’2013) Innovation in Engineering, Technology and Education for Competitiveness and Prosperity” August 14 - 16, 2013 Cancun, Mexico". ) that the surface temperature of Bogotá has changed through time. In the following images, it is presented the variation in the surface temperature of Bogotá determined with landsat images. ![Surface temperature Bogota][3] (surface temperature in Bogotá in the years 2005 and 2012) [1]: https://edxuploads.s3.amazonaws.com/14583341376697376.jpg [2]: https://edxuploads.s3.amazonaws.com/14583349148363718.jpg [3]: https://edxuploads.s3.amazonaws.com/14583356171890895.jpg **2. Measures Proposed** In my opinion, in my city we need first of all change the mindset that development is just building new concrete structures, and instead we need to promote the preservation and expansion of the wetlands, green zones. Furthermore, it is necessary that we study exhaustively the Sabana in order to take advantage of his ecological benefits in damping the climate change . Additionally, It is necessary that the city plants more trees in the places highly transited. Other alternatives are the green roofs and facades in order to reduce the amount of reflexion. Moreover, It is mandatory that strong regulations are implemented for industries so as that the polution levels are reduced. **3. Is UHI effect concerning policy making in your area?** Currently, the majority of policies that are being implemented in the city correspond at those to mitigate the climate change impacts and its causes; however, in the specific aspect of UHI is really little what has been done. Most of the contributions to reduce UHI come from isolated private, and public projects, but Bogota's society is not really involved (even It is unknown the existence of the concept UHI.
