Sustainability, Vol. 12, Pages 947: Spatial Planning Policy for Sustainability: Analysis Connecting Land Use and GHG Emission in Rural Areas (Sustainability)

Anthropogenic greenhouse gas (GHG) emissions are the highest they have ever been and the climate change they have triggered is having consequences on both human and natural systems. The aim of the paper is to demonstrate that an integrated reading of urban and rural land uses in relation to GHG emissions is feasible and useful at the regional level in order to reach emissions reduction. The Po Valley in Italy is an emblematic case study because its features are unique in Europe for high population density, urban sprawl, intensive agriculture, livestock management and consequently high emission levels. The methodology examines the total GHG emissions in relation to urban and rural areas. Between 2000 and 2010, the trend of CO2-equivalent emissions for the macro-regions of Italy shows a national decrease in contrast to the area of our case study which has seen a steady increase and growth trend over time. The paper analyzes some possible reasons linked to this anomaly, and it presents an estimation of the CO2-equivalent emissions related to the use of agricultural land. The main output of the paper is a new overview for research that aims to propose integrated solutions and policies at the local level with a wider vision focused on GHG emission knowledge, supported by Strategic Environmental Assessment.
