Ítem 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, CatalinaClimate 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.Ítem 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, AlejandroPurpose - 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.Ítem Sulfur-controlled iron isotope fractionation experiments of core formation in planetary bodies(PERGAMON-ELSEVIER SCIENCE LTD, 2015-01-01) Shahar A.; Hillgren V.J.; Horan M.F.; Mesa-Garcia J.; Kaufman L.A.; Mock T.D.; Shahar A.; Hillgren V.J.; Horan M.F.; Mesa-Garcia J.; Kaufman L.A.; Mock T.D.; Universidad EAFIT. Departamento de Ciencias; Geología Ambiental y TectónicaA series of high pressure and temperature experiments were conducted to better constrain the Fe isotope fractionation during core-mantle differentiation in planetesimal and planetary bodies. Synthetic mixtures of oxides and metal having varying amounts of sulfur, approximating terrestrial and Martian compositions, were melted at 1-2GPa and 1650°C. Iron isotopic equilibrium between the resulting metal and glass run products was verified for all experiments using the three-isotope technique. Purified Fe from metal and glass was analyzed by multiple-collector ICP-MS in high resolution mode. Iron alloy and silicate glass show a well-resolved d57Femetal-silicate of +0.12±0.04‰ in a sulfur-free system. Isotope fractionation increases with sulfur content to +0.43±0.03‰ at 18wt.% sulfur in the metal. These results cannot be easily interpreted within the context of known Fe isotope ratios in most natural samples of planetary and asteroidal mantles and therefore suggest more complex processes affected the Fe isotope fractionation therein. However, to reconcile Martian meteorite iron isotopic signatures with geophysical models using this new experimental data requires a smaller amount of sulfur in the Martian core than previous estimates, with an upper limit of ~8wt.%. © 2014 Elsevier Ltd.
