Agustín Codazzi Geographic Institute (IGAC)

His professional life began at the Agustín Codazzi Geographic Institute.[2] During the period from 1957 to 1959 he worked as a calculator of the country's geodetic structures. In 1959 he was appointed engineer of the Photogrammetry Division, where he was in charge of the cartography section and learned to make plans from aerial photographs.[1]​.

In 1961, he was appointed Director of the General Charter, a section of the IGAC that manages the general plans of the country. There the first maps were made at a scale of 1/25,000 and 1/6,000, along with the first maps of La Guajira.[2]​ In 1967, he was appointed National Director of Cadastre (1967-1969), and was in charge of the direction that carried out the cadastre of more than two million properties in Cundinamarca, Valle del Cauca and Santander.[2]​.

The relationship with the IGAC ended after his appointment as Director of the Institute (1969-1973). During this period, the filmmaker Gabriela Samper was hired as public relations director, who guided the Institute's vision towards a relationship with environmental thinking. There begins the meeting of different people, including the ecologist Enrique Pérez Arbeláez, professionals in architecture, biology, civil and forestry engineering, in order to introduce environmental thinking in the country. Additionally, among his contributions are the elaboration of the analytical history of the Agustín Codazzi Geographic Institute (IGAC) and the methodology for an economic geography, the analysis of scientific development in relation to national problems and the atlas of science in Colombia.[2]​.

Relationship with Enrique Pérez Arbeláez and the Botanical Garden of Bogotá

Since entering IGAC, he began to get to know and progressively get closer to the figure of Enrique Pérez Arbeláez, founder of the Botanical Garden of Bogotá and who influenced the vision of complex environmental thinking that would be developed later.

Enrique Pérez Arbeláez served as head of the Department of Geoeconomic Research where he promoted the study of Colombia's natural resources based on Holdridge's system of life zones, which was the first ecological map of the country.[15] This dialogue between agrology and ecology caught the attention of Julio Carrizosa, who was interested in the studies published by Enrique Pérez Arbeláez and the interdisciplinary study of ecology that matured during his stay and training in the United States.

Once appointed general director of IGAC in 1969, the relationship with Enrique Pérez was strengthened through initiatives such as the change of Bogotá's trees, the creation of the magazine Colombia Geografía")[7][8]​ and participation in the Colombian Society of Ecology").[16]​.

Their joint work to transform the trees in the city of Bogotá involved replacing the planting of pines, eucalyptus and acacias with species such as cedars, walnuts and sabanero rubber), whose seeds were beginning to be propagated by Enrique Pérez in the botanical garden. They in turn sought to influence the gardening clubs[17] that had already been established in different cities, through the first fairs of native trees and propaganda regarding the benefits of planting these native species.

National Institute of Renewable Natural Resources and the Environment (INDERENA)

In 1973, he held the position of general manager of INDERENA,[18]​ institute created by Carlos Lleras Restrepo to define policies on the country's natural resources. His appointment was granted by President Misael Pastrana, at a time when Carrizosa had already begun to address the ecological issue, forming a group of biologists, architects, and politicians, with whom he analyzed the situation in the country. Pastrana considered that Carrizosa could solve the problems of INDERENA, generated especially by the confrontations between developmentists and conservationists who did not reach a consensus on issues associated with the hunting and export of animal species.

He remained for five years, until the government of Julio César Turbay began in 1978. During these years he formed a multidisciplinary group with which he organized the first environmental meeting in Colombia on ecology and urban planning, from which the idea of ​​creating the National Code of Renewable Natural Resources and Environmental Protection arose,[19] approved in 1974.

Since the approval of this code and during the presidential term of López Michelsen, interest in environmental issues increased, reaching different disciplines and promoting the creation of 17 National Natural Parks "Parques Nacionales Naturales (Colombia)"), the association of artisanal fishermen and the delivery of a Pacific forest reserve to the so-called "corteros", young farmers of that region, in order for them to reforest it in exchange for the use of the wood they They sold to construction companies.

Institute of Environmental Studies (IDEA)

In 1993 he entered the National University competition to aspire to the position of Director of the Institute of Environmental Studies. This, in the context of the deterioration of the health of Professor Augusto Ángel Maya, former director of IDEA, who had to return to Manizales, abandoning his position. Due to his proven track record in promoting environmental thinking throughout his professional career, he held the position of director of IDEA during the period from 1993 to 1998.

In this interdisciplinary space, in which Augusto Ángel Maya had incorporated the discussion of the concept of environment, the proposal was born to create a master's course called Master's Degree in Environment and Development, as an alternative to promote the vision of environmental thinking of Augusto Ángel Maya and Professor Ernesto Guhl Nannetti") in society.[20]​.

Once his time as director of the IDEA ended, from 1998 to 2000 he was employed as an associate professor at the same institute and as a full professor until 2004, the year in which he retired.

His time at the National University of Colombia as a student, his subsequent arrival as director at IDEA and his involvement as a teacher, allowed him to spend more than half of his life on campus, making it his second home. During his time as director of IDEA and through the creation of the university ecology committee, they planted native species such as walnut trees and cedars in gardens on the UNAL campus.

Complex environmentalism

Julio Carrizosa Umaña's environmental vision is based on a deep and holistic understanding of environmental problems, considering them as complex and multifaceted entities that require systemic solutions.[22]​ He emphasizes the importance of recognizing the interconnections and relationships between the components of an environmental system. This view also highlights a multi-causal understanding of problems, recognizing the interaction of multiple factors and processes. Likewise, it highlights the diachronic perspective, understanding environmental problems over time and their historical evolution.[23]​.

This approach involves participatory and democratic environmental management, involving local communities and other relevant actors in decision-making. The key aspects of complex environmentalism are:.

In September 2012, the Higher University Council of the National University of Colombia awarded the title of honorary doctor to Jorge Velosa, Emilio Yunis, Julio Carrizosa and Dicken Castro, each for their contributions to culture, genetics, engineering and architecture, respectively. This distinction is a recognition of the significant contributions that these professionals have made in their respective fields and their positive impact on society.[24]​.

According to Resolution 128 of the Higher University Council, the distinction is awarded to Professor Julio Carrizosa for "excellence in his teaching and research work, his performance as a public servant in high positions in the national order, the development and implementation of public policies, among these the National Code of Natural Resources, a pioneering public policy worldwide, and the direction of the Institute of Environmental Studies IDEA of the National University of Colombia."[25]​.

Professor Carrizosa has been distinguished with various recognitions and designations in his career. He was a full member of the Colombian Society of Engineers and of the Board of Directors of the Colombian Society of Economists between 1971 and 1973. He has also been a full member of the Geographical Society of Colombia and vice president of the Colombian Society of Ecology in 1978. In addition, he received the title of honorary member of the Cartographic Society of Colombia, the Association of Fisheries Researchers, and the Colombian Association of Geographic Engineers. During his career, he held the position of president of the Environment Committee of the Pan American Institute of Geography and History between 1973 and 1976, and was a corresponding member of the Ecuadorian Institute of Natural Resources. He was also elected Honorary Member of the Colombian Academy of Exact, Physical and Natural Sciences on July 7, 2014.[15]​.

The Lepanthes carrizosana") is a species of orchid discovered in 2022 in the Farallones of Cali, in southwestern Colombia, with a small, distinctive flower, named in homage to the life and work of Professor Julio Carrizosa Umaña.[26]​.

Lepanthes carrizosana is a species of orchid belonging to the genus Lepanthes, found in the subtribe Pleurothallidinae of the family Orchidaceae, medium in size, with small flowers found in a congested cluster on the leaves. The leaves are thin, leathery, ovate, long acuminate, with an emarginate apex and an abaxial apex in the center. Its petals, which are its most striking feature, have an oblong-ovate upper lobe, much longer than the small triangular lower lobe.[26]​.

The Faculty of Engineering of the National University of Colombia, https://ingenieria.bogota.unal.edu.co/es/, created the Julio Carrizosa Umaña Pinsus Chair in 2020 to disseminate his work and ensure that students from all academic programs of the National University of Colombia and even other universities in Latin America could study the complexity of sustainability guided by the life and work of Master Carrizosa. The Chair is a space to promote in future professionals training in complex and critical thinking aimed at facing the social, environmental and productive future of our planet, without making distinctions in professional exercises or areas of knowledge. It is created as a response to the climate crisis and is positioned as a Latin American Chair of Environmental Thinking and Climate Crisis, with the support of Klimaforum Latinamerican Network (KLN) https://www.laredkln.org/.
