Estudo dos impactos ambientais causados pela implantação de uma obra rodoviária - DF-003, Brasília/DF

Abstract

The study on the environmental impacts of the expansion of Highway DF-003 (Ligação Torto Colorado - LTC) in the Federal District examines the environmental challenges and urban mobility policies associated with road construction projects. The research aims to identify and present the main environmental impacts resulting from the implementation of road projects; to examine urban mobility within the Brazilian context, considering public policies guiding the sector; to analyze the specific environmental consequences of the DF-003 expansion project, in the section known as Ligação Torto Colorado (LTC); and to discuss effective mitigation strategies for the resulting environmental impacts, aiming to minimize the negative effects on the local ecosystem and to promote sustainable development practices. However, road projects can lead to significant consequences, including biodiversity loss, disruption of the hydrological cycle, and habitat fragmentation. The study emphasizes the importance of balancing development and environmental conservation to mitigate these impacts. The methodology is based on documentary analysis and case studies, focusing on the effectiveness of mitigation measures such as water monitoring and wildlife protection, as established by Brazilian environmental legislation. These measures propose actions to minimize impacts on physical, biotic, and socioeconomic environments, encouraging sustainable development practices. Among the proposed measures are the preservation of natural areas, installation of wildlife passages, and monitoring of water and soil quality to reduce erosion and contamination. The study evaluates these actions to assess their effectiveness in protecting local ecosystems. Key identified impacts include biodiversity loss and habitat fragmentation, which threaten native species and hinder connectivity between natural areas. Fragmentation disrupts the movement of animals and plants, impacting the region’s ecological balance. Interference with the hydrological cycle is another significant impact, as the project alters natural drainage patterns and may affect water resources. Thus, water monitoring is crucial to detect changes in water quality and to prevent issues such as flooding and erosion, common in large infrastructure projects. The study also evaluates socioeconomic impacts. Although the highway expansion may benefit the local population by improving access and the circulation of goods, it can also bring adverse effects, such as community displacement, increased noise, and air pollution. Therefore, it is essential that mitigation measures address not only the natural environment but also the quality of life of affected communities. The research concludes that the effective implementation of mitigation practices is fundamental to reducing the environmental damage caused by road projects. Preserving remaining natural areas, installing wildlife passages, and continuously monitoring the environment help to minimize ecosystem impacts and to protect biodiversity. Furthermore, adherence to environmental legislation and oversight of mitigation actions foster sustainable development, allowing economic growth without compromising the environment. Balancing development and environmental conservation ensures that society benefits from essential infrastructure while preserving natural resources for future generations.
