Land consumption in Italy

This paper illustrates a land consumption map for Italy (year 2017) at a scale 1:1,300,000, and the assessment of its changes (2012–2017). We define land consumption as the replacement of a non-artificial land cover to an artificial land cover, both permanent and no-permanent. The maps are a 10 m spatial resolution raster, produced by photointerpretation of very high resolution images and semiautomatic classification of high resolution remote sensing images. An overall accuracy of 97.7% for the map of 2012 and of 99.66% for the map of 2017 was obtained. The results suggest that the method proposed is appropriate to detect land consumption, both for the urban densification and for the sprawling phenomena, from national to local level. Furthermore, because of the high spatial resolution and the classification scheme adopted, it is suitable for an effective monitoring system, compared to other existing classification systems or monitoring programs

Sustainable settlement development - Assessing the effects of state measuresin scenario analysis

The underlying research project was sponsored by the German Federal Ministry of Education and Research (BMBF) in the funding programme “Research for the Reduction of Land Consumption and for Sustainable Land Management” (REFINA). REFINA is implemented by the BMBF in cooperation with the Federal Ministry of Transport, Building and Urban Affairs (BMVBS) and the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU). Since 2006, the projects funded have developed innovative concepts for reducing the rate of land consumption and for encouraging sustainable land management.15th International Sustainable Development Conference

Towards Land Consumption Neutrality and Natural Capital Enhancement at Urban Landscape Scale

Among the UNCCD SDGs 2030, there is the recognition that land consumption can strongly affect the provision of ecosystem services. From the perspective of land degradation neutrality, urban level is the right scale when planning actions against land consumption. The aims of this research are: (1) to assess land consumption at urban landscape scale and its effects on natural capital flow provision; and (2) to identify sustainable strategic planning choices for land consumption mitigation and natural capital enhancement. We propose and test an approach based on multi-temporal landscape spatial analysis (land use/land cover map, land consumption map, and landscape metrics) and ecosystem services’ flow assessment for the identification of areas at risk of loss of natural capital flow. The results have shown that from 2006 to 2019, land consumption has increased with a consequent decrease of natural capital flow. LULC dynamics has been analyzed in terms of landscape risk to lose natural capital flow, highlighting that the management of Galatone urban landscape is still far from land consumption neutrality. Landscape metrics have allowed the analysis of the aggregation among land consumption areas. The mitigation of land consumption should be based on the identification of suitable nature-based solutions towards the balance between past land consumption and future land recovery

Open Space Loss and Land Inequality in United States' Cities, 1990–2000

Urban growth reduces open space in and around cities, impacting biodiversity and ecosystem services. Using land-cover and population data, we examined land consumption and open space loss between 1990 and 2000 for all 274 metropolitan areas in the contiguous United States. Nationally, 1.4 million ha of open space was lost, and the amount lost in a given city was correlated with population growth (r(272) = 0.85, P<0.001). In 2000, cities varied in per capita land consumption by an order of magnitude, from 459 m2/person in New York to 5393 m2/person in Grand Forks, ND. The per capita land consumption (m2/person) of most cities decreased on average over the decade from 1,564 to 1,454 m 2/person, but there was substantial regional variation and some cities even increased. Cities with greater conservation funding or more reform-minded zoning tended to decrease in per capita land consumption more than other cities. The majority of developed area in cities is in low-density neighborhoods housing a small proportion of urban residents, with Gini coefficients that quantify this developed land inequality averaging 0.63. Our results suggest conservation funding and reform-minded zoning decrease per capita open space loss

Geospatial analysis of urban sprawl in Ile-Ife city, Nigeria

This paper assesses the effects of urban expansion of Ile-Ife city and appraises the changes that occurred in the landscape from 1986 to 2009. The study made use of information extracted from Landsat TM 1986, ETM+ 2002 and Ikonos 2009 images. GPS observations of notable points within and around the city were overlaid on the topographic map and on the satellite imageries in order to appraise the changes in the land use and land cover over the period. The land consumption was analyzed using the computed land consumption rate (LCR) and land absorption coefficient (LAC) from 1986 to 2009. The average annual rate of urban expansion of Ile-Ife is 3.5% which translated to a gain of 2256.7 ha in the surrounding rural areas from 1986 to 2002 and about 1434.7 ha between 2002 and 2009. The land is being transformed as shown by the land consumption rate which progressed from 1.1% in 1986 to 1.2% in 2002 and remained stable till 2009. The land absorption coefficient has increased from 0.013 to 0.014, confirming the high demand for land both within the city and in the suburbs.Keywords: Urban Sprawl; Land Consumption Rate; Land Absorption Coefficient, Ile-Ife; Remote Sensin

Urbanization processes along the Mediterranean coast of Alicante province.

The rate of land consumption in the coastal area of Alicante has been over the last decades, one of the highest among all Spanish Mediterranean provinces. This new territorial tendency has involved important changes in the use of land and has led to a new spatial and functional reality. The objective of this paper is to address two specific concerns related to the identification and characterization of these recent artificial surfaces, focusing on the assessment of quantitative details (land consumption surface, density, population, etc.) and qualitative features (morphologies, landscape impact, etc.). The methodological approach is based on graphic and statistical analysis. On the one hand, starting by first identifying artificial areas by comparing satellite imagery (source: the European project Corine Land Cover – 1990, 2000 and 2006). It is possible then, to study in detail the new developments thanks to the aerial photographs (1993, 2002 and 2008). On the other hand, the variety of statistical databases –local, regional and state statistics such as census, registers and other government studies- make possible to quantify and qualify the details of these new urban areas. Thus, the foreseen results are related to the characterization and definition of new urban patterns along the coast of Alicante, taking in account that the identification of the new patterns of urban and territorial occupancy is an important clue in order to establish future planning in both local and regional level.

Eco-Industrial Parks and Sustainable Spatial Planning: A Possible Contradiction?

The definition and the subsequent development of eco-industrial parks (EIPs) have been deeply based on the application of industrial ecology theory, which pays specific attention to metabolic exchanges within industrial processes to address a deep reduction of limited resource consumption and a minimization of waste production in the framework of a sustainable development approach. Despite the EIPs configurations being essentially based on the overall idea of sustainability, the problem of defining their proper location inside the territory and the consequent land use model, to minimize land consumption, have not always been central in the wide range of studies and practices concerning the EIPs. Nevertheless, the specific problem of a drastic reduction of land consumption at the EIP planning stage acquires a crucial role and, therefore, needs to be carefully assessed inside the perspective of sustainable urban development. In this framework, the paper firstly aims at facing the nontrivial relationship between the EIPs' theorizations and implementations and the reduction of land consumption by referencing specific studies and shared tools, where new developments have been favored despite the conversion and redevelopment of existing industrial park
