Análisis del valor del suelo antes y después del fenómeno de la Niña 2010-2011 y la Influencia de las actuaciones tomadas por las entidades oficiales para la UPZ 55 Diana Turbay

Abstract

Bogotá with a population that exceeds 7 million inhabitants, in the context of a notable environmental fragility and with a clear trend towards accelerated urbanization, faces the challenge of administering in a sustainable and efficient way the use and occupation of its territory that with Its 20 locations and 111 UPZ´s are considered the administrative and political center of the country. The average annual cost of disasters amounts to billions of pesos for losses that especially affect the poorest segments of the population and prevent and limit the implementation of sustainable patterns of economic and social development, aggravating poverty levels in the capital of Colombia. According to the risk management in the Andean countries, it says that recently created data, Colombia in the last 37 years has accounted for about 23 thousand records of losses of varying magnitude, more than 3 million victims and more than 22 million affected in the population exceeding the indexes of the other countries, which constitutes a real threat to development and puts at risk the investments and other efforts that are carried out to reduce poverty within the framework of the Development objectives. The land is a component that becomes very important in the city, since through the collection of taxes and its valuation year after year benefits both the city and its owner. Due to the above, natural phenomena have a great impact on the loss or gain of value in this essential component for a city. The following case study specifically refers to the phenomenon of the girl experienced by the country in 2010 and 2011, where there was heavy rainfall, which generated flooding and mass removal phenomena, punctually at UPZ 55 Diana Turbay from the city of Bogotá, a sector located in the north-eastern part and it is an area developed mostly by self-construction with a little planning, which in many parts represents a threat zone for removal in a higher category and therefore phenomena like these greatly affect the soil present there. There are several components that are taken into account to determine the value of the soil, for this reason we have decided to perform a multitemporal analysis where the value of the soil can be evidenced before the girl's phenomenon and at present, in order to determine if it had some impact on the valuation to which the lands are subject each year and if the actions of the different State entities mitigated that affectation that it could have.
