The all city reveals stocks and flows in every part of the system. Three of them might be the external and internal migration of population (during several years) mainly because of the arm conflict. The second, related to this one, the construction of new services equipment to shelter the increasing population, one of the being the arising of vertical housing projects that at same time produces, among others, the new flow linked to production of construction and domestic waste, which has to be treated. By 2014, the city of Bogotá has received 350.000 displaced population from the arm conflict (http://lasillavacia.com/queridodiario/bogota-capital-mundial-del-desplazamiento-48162), that has mainly affected the peasant workers that left their territories and traditional occupation and move to the capital, looking for protection. This first flow, has created a particular configuration of the city, that reflects the diversity of the regions of Colombia that make presence now in the city and trying to remain close to their traditions, such as the stands (stocks) with variety of gastronomic samples and the display of musicians that reproduce the sounds of their origins. ![ingrese la descripción de la imagen aquí][1] However, now almost 9.000.000 people live in the city and receiving new flows of migrants has placed big pressure on the land, because the location of housing projects near the center is difficult. Land has become insufficient and the cost has increase highly in the last year (27% according with real property enterprises: http://www.institutodeestudiosurbanos.info/noticias-y-eventos/item/escasez-suelo-aumenta-valor-vivienda). Sum to this factor, the internal divergences in the city and the transformation of the arm conflict to urban violence, deliver in new flows in the city that move previous displaced families to another part of the city. ![ingrese la descripción de la imagen aquí][2] Along with this, the local and national government had impulse a housing program in the all country, that in the case of Bogotá can benefit this families affected by the conflict. However, the housing projects are being raised in different parts of the city. As it has been said before, the pressure on the land makes difficult for the local government to give lots for the housing projects close to the center of the city, since it is the highest cost territory, and has left some lots in the surroundings of the urban periphery. ![ingrese la descripción de la imagen aquí][3] In this case the flow, of course, will be related to the transportation of that population to the center of the city and maybe to the north, which is one important laboring focus. Nevertheless, the third flow-stock example was the creation and disposal of construction and domestic waste that is created when all this projects are done. The construction disposal is one major polluting agent, but given the necessity of having housing solutions, the local government has created a system to recollect and recycle the waste. At the same time, a “Zero-Garbage” program was installed in 2013 to treat the domestic waste to reduce CO2 emissions and the quantity of disposals in the landfill. The program has less than 2 years being executed, and has shaped a new flow with a figure called recycler. This are men and women, most of them families with very low income or street inhabitants that used to recycle opening all cans in the city. Now, the classification of the garbage in every house gives the opportunity to the recycler to go around the city collecting the white bags that has the recyclable elements. To finish, the flows of population that has come to the city of Bogotá placed a particular way of living the city, with the “stocks of diversity” that can be looked and lived in every corner. Diversity as well leads to conflict, and the permanent challenge of the city is to encounter the spaces of harmonious dialogue. In the case of the housing projects, sadly the flows land market are not yet been matched with the population flow, a great percentage of families struggle every day to pay rent and have low possibilities to have their own house. The housing projects, gives many families an opportunity, but leaving the flow of transportation at a high cost, since moving from the projects to the city or working places implicates hours spent in traffic and an investment in public transportation services. The implementation of the waste program should lead to a more efficient city, more sustainable, if the local government places a permanent program to educate citizens to recycle and generate new practices that reduce the generation of garbage. This is challenge considering that the flow of population seems not to end, and new people coming to the city have to learn about the program and apply it in their houses.
