There is a deep connection between environmental and economic issues. It can be seen that the development of economic activities has not meant the consideration of socio-environmental aspects in this process, and this inefficiency interferes directly in the resilience of the environment. As an example, road projects, which are considered vectors of socioeconomic development, are also potential sources of negative externalities for society when social costs and private costs are not considered, or when socio-environmental costs and benefits are omitted in the planning of transportation infrastructure projects. Consequently, the failure to internalize the real and related costs related to impacts generated by transportation infrastructure developments, which are either unavoidable or for which no mitigation measures have been found, incurs a loss of natural capital and environmental services, and shares the costs of these losses with society as a whole. This book covers economic concepts, their application to the environment, and their interface with transportation infrastructure developments.
