Análisis de la integración de factores ambientales, sociales y de gobierno corporativo en la administración y toma de decisiones de los bancos del sistema financiero en Colombia
(Universidad Eafit, 2020) Doria Fernández, Andrés David; Vergara Garavito, Judith Cecilia
This paper presents an approach to the advances in environmental, social and corporate governance (ESG) of the banks that make up the Colombian financial system, exposing the theory that relates their corporate performance to good ESG practices. In addition to this identification, the policies that each one applies in terms of ESG were mapped using the following public sources of information: management reports, reports and disclosures, sustainability reports and the Código País implementation report of Superintendencia Financiera de Colombia, among others. Lastly, banks were classified in ranges from highest to lowest compliance or adherence to ESG policies, and an analysis was made of the most profound factors that affect the adoption of ESG policies in the Colombian financial sector.

Purpose - This chapter aims to provide an overview of the Paris Climate Agreement, and to explore the meaning of this universal agreement for business. Design/methodology/approach - This introductory chapter relies on secondary sources, and brings together evidence- based, conceptual and theoretical contributions from a diverse set of geographical locations, and disciplinary backgrounds. Findings - It was found that although there is skepticism about achieving the ambitious set targets in the Paris Climate Agreement, the explicit political will from governments and business alike could be the engine for achieving the goals. Originality/value - This chapter questions if the COP21 is the beginning of the end to the era of oil.
La comunicación en la gobernanza para el cambio climático - el caso del carbón en Amagá
(Universidad EAFIT, 2023) Valencia Bedoya, Andrea del Mar; Cadena Gaitán, Carlos
After the harmful effects of climate change, decarbonization through energy transition is projected as a great goal for the year 2050, and along this path, climate governance triggers collective actions and interactions which determine how power is exercised to care for the planet. This article, based on a qualitative-interpretive study, investigates the existence of communication conditions for a climate governance in Amagá, a coal mining municipality in the department of Antioquia.
Desafíos jurídicos en la lucha contra el cambio climático : perspectivas internacionales y nacionales para la participación efectiva del Estado y el sector privado
(Universidad EAFIT, 2024) Bran Rua , Ana Sofía; Vallejo Piedrahíta, Catalina
Climate change is one of the main challenges we face as a society. For mitigating its effects, businesses play an equally fundamental role as countries; however, national and international regulation on this issue is insufficient in relation to the needs. Currently, the legal framework on this matter lacks the necessary specificity to ensure the accountability of the private sector in combating the effects of climate change. This situation allows many companies to evade their environmental responsibilities, compromising global efforts. This document aims to identify legal deficiencies and propose possible solutions to strengthen the legal framework regarding the role of the private sector in mitigating the effects of climate change.
Determinantes de la adopción de tecnologías de agricultura climáticamente inteligente en Colombia
(Universidad Eafit, 2020) Chinkousky Giraldo, María Antonia; Urrego Morales, María Camila; Muñoz Mora, Juan Carlos
The following work is the product of a research that aims to delimit the determinants in the adoption of Silvopastoral Systems (SSPI) in the Colombian Caribbean region and provide guidance on the public policies that should be followed in Colombia in order to achieve an increase in the implementation of climate-smart technologies. This work seeks to contribute to the efforts to mitigate climate change and at the same time to find tools to address the food challenges associated with population growth trends. The result of the research allowed to identify the socioeconomic and physical factors that encourage the adoption of SSPI in this region, through a Probit type regression.
Development of structural debris flow fragility curves (debris flow buildings resistance) using momentum flux rate as a hazard parameter
(Elsevier B.V., 2018-05-18) Prieto, Jorge Alonso; Journeay, Murray; Acevedo A.B.; Arbelaez, Juan; Ulmi, Malaika; Prieto, Jorge Alonso; Journeay, Murray; Acevedo A.B.; Arbelaez, Juan; Ulmi, Malaika; Universidad EAFIT. Departamento de Ingeniería de Producción; Materiales de Ingeniería
Societal risks associated with debris flow hazards are significant and likely to escalate due to global population growth trends and the compounding effects of climate change. Quantitative risk assessment methods (QRA) provide a means of anticipating the likely impacts and consequences of settlement in areas susceptible to landslide activity and are increasingly being used to inform land use decisions that seek to increase disaster resilience through mitigation and/or adaptation. Current QRA methods for debris flow hazards are based primarily on empirical vulnerability functions that relate hazard intensity (depth, velocity, etc.) to expected levels of loss for a given asset of concern, i.e. most of current methods are dedicated to loss-intensity relations. Though grounded in observed cause-effect relationships, empirical vulnerability functions are not designed to predict the capacity of a building to withstand the physical impacts of a debris flow event, or the related uncertainties associated with modelling building performance as a function of variable debris flow parameters. This paper describes a methodology for developing functions that relate hazard intensity to probability of structural damage, i.e., fragility functions, rather than vulnerability functions, based on the combined hydrodynamic forces of a debris flow event (hazard level) and the inherent structural resistance of building typologies that are common in rural mountainous settings (building performance). Hazard level includes a hydrodynamic force variable (FDF), which accounts for the combined effects of debris flow depth and velocity, i.e. momentum flux (hv2), material density (?) and related flow characteristics including drag (Cd) and impact coefficient (Kd). Building performance is measured in terms of yield strength (Ay), ultimate lateral capacity (AU) and weight to breadth ratios (W/B) defined for a portfolio building types that are common in mountain settlements. Collectively, these model parameters are combined using probabilistic methods to produce building-specific fragility functions that describe the probability of reaching or exceeding successive thresholds of structural damage over a range of hazard intensity values, expressed in terms of momentum flux. Validation of the proposed fragility model is based on a comparison between model outputs and observed cause-effect relationships for recent debris flow events in South Korea and in Colombia. Debris flow impact momentum fluxes, capable of resulting in complete damage to unreinforced masonry buildings (URM) in those regions are estimated to be on the order of 24 m3/s2, consistent with field-based observations. Results of our study offer additional capabilities for assessing risks associated with urban growth and development in areas exposed to debris flow hazards. © 2018 Elsevier B.V.

Estudio de viabilidad de una empresa de energía solar en Colombia
(Universidad EAFIT, 2022) Romero Escobar, Luis Felipe; Escalante Gómez, Juan Esteban
The main goal of the present work was to develop a feasibility study for a solar energy company in Colombia using Onudi methodology, in order to assess its relevance at the investment level. The type of research chosen for developing this work, due to its scope and how the information was treated, is descriptive and mixed, respectively, since it contains quantitative research of an economic and financial nature, and qualitative research to describe and interpret the demand and supply of the market business, customer segmentation and the profiles of the distinct positions that the company needs The main finding of this research is that the profitability of the project has been significantly affected by the current economic situation at national and international level due to the pandemic caused by COVID-19. This is because most of the equipment for a solar energy project must be imported, and the devaluation of the Colombian peso against the dollar has carried to the costs of raw materials and maritime transport had considerably increased during the last two years. Finally, the result of this work provided enough reliable information for the partners to decide to continue with the next stage of the project, the execution, and invest the resources that the company requires.

Implicaciones del cambio climático en las operaciones de los puertos en Colombia
(Universidad EAFIT, 2024) Palacio Machado, María Camila; Pineda Toro, Oscar Maricio; Giraldo Hernández, Gina María
This research work seeks to identify the effect that climate change has had on the operations of port areas in Colombia. For this purpose, an initial review of the concept of climate, its causes and the implications generated is proposed, not only in the economic and operational context but also in the social aspect. Subsequently, a characterization of the environment is made to recognize the vulnerability of the variables, how they interact with each other in the ecosystem and to identify what procedures exist to manage the threats that exist in the logistics processes. In this case, the conceptualization with respect to seaports becomes an important aspect to determine the benefits generated in the social, economic and environmental spheres. Finally, the impacts on the operations system are analyzed and a reference framework is described with various strategies implemented to help mitigate the impacts of climate change when these are negative or unfavorable.
Lecciones aprendidas en la gestión del riesgo de desastres; inundaciones en el año 2018, barrios la asunción y Guadalajara, Copacabana, Antioquia, Colombia
(Universidad EAFIT, 2024) Roquemen Tangarife, Tomás; Acevedo Jaramillo, Ana Beatriz; Henao Arango, María Cecilia
This work documents the lessons learned in disaster risk management for one of the most recurrent phenomena within the Aburrá Valley: floods. This phenomenon is exacerbated by climate change, the rapid impermeabilization of watersheds, and the improper occupation of territory. It is expected that these flood events will have greater magnitude and frequency in the future. The analysis is conducted using the Post-Event Review Capability (PERC) methodology, developed by the Zurich insurance group as part of the Flood Resilience Program, applied to a case study that occurred in 2018 in the Municipality of Copacabana, Colombia. This work is developed to manage knowledge for future flood events.
Maldivian Disaster Risk Management And Climate Change Action In Tourism Sector: Lessons For The Sustainable Development Agenda
(Emerald Group Publishing Ltd., 2017-01-01) Herrera-Cano, Carolina; Herrera-Cano, Alejandro
Purpose - The purpose of this chapter is to address the issue of climate change and its effects on developing insular countries like the Maldives in order to identify adaptive mechanisms and new opportunities in the international context towards achieving sustainable development, taking into account its environmental and social incidences. Design/methodology/approach - Firstly, the chapter introduces some generalities of the Republic of the Maldives and its current challenges. Next, there is a description of the economy of the islands: here the importance of its major source of income, the tourism industry, is highlighted. Then, vulnerabilities and adaptive mechanisms are explored for the particular case of tourism. Findings - Maldivian current efforts in disaster risk management (DRM) mitigation, preparedness, response, and reconstruction stages, and the work between government, private organizations, and civil society, implemented since the 2004 tsunami; and as a response to climate change, are examples of how to apply collaborative approaches proposed by Sustainable Development Objectives, COP21 agreement, and Sendai Framework. Research limitations/implications - It is difficult to measure the consequences of sustainable development actions by the Maldivian government, especially in the international environment. Practical implications - The study of the Maldivian DRM strategy in the context of climate change and the lessons from the Maldives' tourism sector development under climate action serves as a model for other international business organizations which aim to reach sustainable development standards in the Post-2015 Development Agenda. Originality/value - This chapter evaluated important opportunities for sustainable development agenda that can be learned from DRM measures in Maldives.
