La valoración económica de cambios en servicios del ecosistema: Una aplicación de la metodología CGE

Abstract

<span>The present study integrates Computable General Equilibrium (CGE) modelling with biodiversity services, proposing a possible methodology for assessing climate-change impacts on ecosystems. The assessment focuses on climate change impacts on carbon sequestration services provided by European forest, cropland and grassland ecosystems and on provisioning services, but provided by forest and cropland ecosystems only. To do this via a CGE model it is necessary to identify first the role that these ecosystem services play in marketable transactions; then how climate change can impact these services; and finally how the economic system reacts to those changes by adjusting demand and supply across sectors, domestically and internationally.</span>

Exploring macroeconomic models in the water, energy, food, and ecosystem (WEFE) field: a comprehensive review

“…The CGE literature analyzes the ecosystem dimension by focusing directly on the impact of climate change on ecosystem services (especially in terms of carbon sequestration, as in Bosello et al 2011), or indirectly by considering the impact of climate change on other WEF elements, in particular water and food, through changes in the availability of certain ecosystem elements, such as soil salinity (Osman et al 2019), soil erosion (Sartori et al 2019), and agricultural production (Bosello et al 2011, Kahsay et al 2017, Khan et al 2020, Vatankhah et al 2020.…”

“…Starting from the direct linkages between climate change and ecosystem services, the study of Bosello et al (2011) represents a significant effort to delineate the role of ecosystem services in market transactions. That is achieved by estimating the value of carbon sequestration services provided by forest, cropland, and grassland ecosystems in the EU and by assessing how climate change could potentially affect them, using various indicators such as changes in land productivity, land loss due to sea-level rise and changes in energy consumption.…”

Development of a computable general equilibrium model based on integrated macroeconomic framework for ocean multi-use between offshore wind farms and fishing activities in Scotland

“…Natural capital has been integrated into CGE model only for the agriculture (Allan et al, 2018) and forest (Ochuodho and Alavalapati, 2016) sectors but has not been applied on the marine environment. There are previous CGE models that have extended frameworks with links to ecosystem services (Bosello et al, 2011;Carbone et al, 2013) and have been applied on the marine environment such as harvested fish (Finnoff and Tschirhart, 2008;Jin et al, 2012), though not to natural capital such as fish stock. There is a lack of practical application on the marine economy where both natural capital and ecosystem services are linked with the theoretical CGE framework.…”
