"Development of a global economic-land use model (GTEM-AEZ) for analysis of climate change impact and agricultural productivity" by Tran, Trang, Duy Nong, George Verikios and Raymundo Marcos Martinez Abstract With a vital role of agricultural sectors and associated land use in addressing climate change and food security, science-based research to raise awareness of the public and to inform policymakers become crucial. We extended our modelling GTEM (Global Trade Environmental Model) by incorporating the land use mechanism in GTAP-AEZ into GTEM, becoming the GTEM-AEZ model to evaluate the impact of economic and environmental issues. We also develop a data routine program to transform GTAP land use data to the data used for the GTEM-AEZ model. For such development, we identified several bugs and incomprehensive features in the database. We aim to document how to develop the land use mechanism in GTEM-AEZ model and how to develop program to transform GTAP land use to GTEM land use data, fix bugs. In the GTEM-AEZ model, 18 AEZs (Agro-Ecological Zones) land are substituted via CES (Constant Elasticity of Substitution) function in the production structure, and we constructed a three-level nested CET (Constant Elasticity of Transformation) functional form to allow land transformation in the land supply. For the database, all 141 regions and 65 sectors in GTEM data are aggregated into 22 regions and 43 industrial sectors, with disaggregated all land using sectors and food sectors. The baseline scenarios are built on the projection of GDP, population, and labour supply along with energy efficiency in agricultural sectors, transportation sectors and agricultural productivity forecasted by 2050. For the policy scenario, we aim to analyse the impact of climate change, along with agricultural productivity development. |
