A Theoretical Learning Model Combining Stochastic Cellular Automata and Economic Indicators to Simulate Land Use Change
2015
The study of change in land use has been included in territorial planning to inform spatial planners and policy makers of the possible developments they face in order to optimize future management decisions. In this paper the authors present the core of an original learning model coupling stochastic Cellular Automata and economic indicators to simulate the land use change. This model is an important step in building an “environmental virtual laboratory” to explore, explain and forecast land use change.
Political Challenges, Best Practices and Recommendations for Energy Sustainable Municipalities
2016
Integrated system solutions, together with improved management of municipal infrastructure and environments, are essential to address energy challenges. A number of aspects should be examined and developed, including eco-cycle models demonstrating integrated solutions for energy, waste and water, integrated land use and transportation, ecosystems planning, sustainable building design, and strategies to reduce air pollution. It is imperative to apply the principles of sustainable development and support smart solutions today if we are not to compromise the ability of future generations to meet their needs tomorrow. We should think of urban systems as living organisms and find synergies betwe…
Soil Mapping and Processes Modeling for Sustainable Land Management
2017
Soil maps and models are indispensable tools in sustainable land management. The sustainable land use of our territory is fundamental to providing long-term socio-economic and environmental benefits. The risk of land degradation and corresponding declines in ecosystem services depends on the type of land use. Soil restoration can be extremely expensive, more than the implementation of sustainable land use practices. This is especially important in the context of climate change and the increasing pressure that a growing population places on soil resources, which is a global phenomenon. The objective of this chapter is to show the advantages of using soil mapping and modeling in sustainable l…
Global Upscaling of the MODIS Land Cover with Google Earth Engine and Landsat Data
2021
Image classification has become one of the most common applications in remote sensing yielding to the creation of a variety of operational thematic maps at multiple spatio-temporal scales. The information contained in these maps summarizes key characteristics related with the physical environment and provides fundamental information of the Earth for vegetation monitoring or land use status over time. However, high spatial resolution land cover maps are usually only produced for specific small regions or in an image tile. We present a general methodology to obtain a high spatial resolution land cover maps using Landsat spectral information, the powerful Google Earth Engine platform, and oper…

Impact of woody encroachment on soil organic carbon and nitrogen in abandoned agricultural lands along a rainfall gradient in Italy
2011
Land use changes represent one of the most important components of global environmental change andhave a strong influence on carbon cycling. As a consequence of changes in economy during the last century, areas of marginal agriculture have been abandoned leading to secondary successions. The encroachment of woody plants into grasslands, pastures and croplands is generally thought to increase the carbon stored in these ecosystems even though there are evidences for a decrease in soil carbon stocks after land use change. In this paper, we investigate the effects of woody plant invasion on soil carbon and nitrogen stocks along a precipitation gradient (200–2,500 mm) using original data from pa…
Subversion of land-use plans and the housing bubble in Spain
2011
The exceptional rhythm of the construction of residential dwellings in Spain between 1997 and 2006 and its geographical contrasts are explained by a time of economic expansion, a political and social context favourable to unlimited growth and excessive and untempered municipal land-use plans with passive or complicit regional governments. The lack of effective land-use regional plans and the discrediting of municipal land-use plans are a manifestation of a deliberate subversion of public planning to subordinate the public interest to the developer's demands. This article concludes by presenting a panorama of the disturbing consequences of this urban development model.
Economic theory and space : a reconciliation
1997
Malgré des apports importants au XIXe siècle et dans la première moitié du XXe et en dépit des efforts de l'après guerre, l’économie spatiale est longtemps restée un domaine marginal par rapport au corpus principal de la théorie économique. L’attachement aux hypothèses de concurrence pure et de rendements non croissants explique en grande partie cette séparation. Depuis quelques années, on assiste, dans le cadre de l'Economie géographique, à un mouvement d’intégration dont le moteur principal est la reconnaissance et l’exploitation des rendements croissants comme explication de la formation de l’espace économique. Ce papier présente un panorama de 25 années d’économie spatiale en soulignant…
The impractical supremacy of the local identity on the worthless soils of Mappano
2016
Introduction Soil is under pressure worldwide. In Italy, in the last two decades, land consumption has reached an average rate of 8 m2, demonstrating the failure of urban planning in controlling these phenomena. Despite the renewed recognition of the central role of soil resources, which has triggered numerous initiatives and actions, soil resources are still seen as a second-tier priority. No governance body exists to coordinate initiatives to ensure that soils are appropriately represented in decision-making processes. Global Soil Partnership draws our attention to the need for coordination to avoid fragmentation of efforts and wastage of resources. Both at a global and at a local level, …
Effetti di urbanizzazione e cambiamenti climatici sui deflussi a scala di bacino
2016
Fra le pressioni di natura antropica agenti sui bacini idrografici, particolare rilevanza hanno sia la progressiva perdita di suoli naturali in favore di suoli poco, o per nulla, permeabili (es. strade, edifici, parcheggi, etc.) che la regimazione e regolazione dei deflussi sulla rete di drenaggio naturale mediante interventi idraulici. In particolare, l’ultima relazione sullo stato dell’ambiente europeo a cura dell’Agenzia Europea dell’Ambiente (AEA, 2010) considera l’impermeabilizzazione dei bacini naturali come uno dei maggiori processi di degrado del suolo. L’aumento del grado di urbanizzazione dei bacini naturali, inteso come aumento della frazione impermeabile del suolo derivante dell…
