Reasons for introducing 3D property in a legal system—Illustrated by the Swedish case

Journal Articles & Books
Décembre, 2013

The use of three-dimensional (3D) property rights has for many years been a tool for providing secure and lasting rights for the use of land and its volume of space in complex situations involving land use in the urban society. The aim of this article is to investigate the reasons for introducing 3D property in a legal system. This is illustrated by using the Swedish system as an example. In general, without the possibility of forming 3D property units with direct ownership, other forms have to be used, such as indirect ownership or granted user rights.

Evaluation of Ecosystem Services related to Bio-Energy Landscape Connectivity (BELC) for land use decision making across different planning scales

Journal Articles & Books
Décembre, 2016

Landscape connectivity is of paramount importance not only in maintaining both functionality and resilience of social-ecological systems, but also in providing Ecosystem Services (ESs). Despite recent efforts, several issues still need to be faced to fully integrate ESs evaluation relating to landscape connectivity into effective plans and environmental assessment procedures. Choosing an appropriate scale of analysis is one of the most problematic topics, since it can profoundly affect the evaluation of single patch contribution to global connectivity.

assessment of the effectiveness of a rotation forest ensemble for land-use and land-cover mapping

Increasing the accuracy of thematic maps produced through the process of image classification has been a hot topic in remote sensing. For this aim, various strategies, classifiers, improvements, and their combinations have been suggested in the literature. Ensembles that combine the prediction of individual classifiers with weights based on the estimated prediction accuracies are strategies aiming to improve the classifier performances.

Environmental assessment tools for multi-scale land resources information systems. A case study of Rwanda

Journal Articles & Books
Décembre, 2006
Rwanda

Sustainable land use planning involves both policy- and farmer-oriented agricultural land use strategies. In this paper, a spatially and temporally explicit multi-scale decision support system that reveals the biophysical indicators affecting land use choices of these different stakeholders, is explained and demonstrated. It comprises three different environmental assessment tools, designed to run with data supplied by traditional soil surveys and organised into a land resources information system.

Monitoring land use and land cover change using remote sensing, markov analysis, population and landscape metrics analysis : a case study from Çanakkale (1987-2010)

Policy Papers & Briefs
Décembre, 2013
Turquie

Population growth in cities along with migration from rural areas dramatically increases the Land Use and Land Cover (LULC) changes. This study was conducted in Çanakkale province consisting of central part and its vicinities where rapid population growth and development have been taken place. This study aimed to determine LULC changes using remotely sensed data and geographical information system (GIS) techniques between 1987 and 2010.

Managing semi-arid woodlands for carbon storage: Grazing and shrub effects on above- and belowground carbon

Journal Articles & Books
Décembre, 2013
Australie

Shrub cover has increased in semi-arid regions worldwide. This change has generally been viewed as land degradation, due to shrub-induced declines in pastoral productivity. As a consequence, widespread management treatments to reduce shrub density have been applied in many pastoral areas. These treatments, however, often do not have long-term positive benefits for forage production.

Motivations and Land-Use Intentions of Nonindustrial Private Forest Landowners: Comparing Inheritors to Noninheritors

Journal Articles & Books
Décembre, 2009

The documented importance of intergenerational human capital transfers in agriculture generally gives us reason to suspect that such transfers may be important in a forestry context and that there may be important implied differences between first-generation woodland owners and multigeneration woodland owners with respect to their motivations and future intentions.

Land use history alters the relationship between native and exotic plants: the rich don't always get richer

Journal Articles & Books
Décembre, 2010

Observational studies of diversity have consistently found positive correlations between native and exotic species, suggesting that the same environmental factors that drive native species richness also drive exotic species richness, i.e., “the rich get richer”. We examined patterns of native and exotic plant species richness in temperate forests that have been undergoing reforestation since the turn of the twentieth century to test the influence of disturbance arising from land-use history on this relationship.

Use of Goats Grazing to Restore Pastures Invaded by Shrubs and Avoid Desertification: A Preliminary Case Study in the Spanish Cantabrian Mountains

Espagne

Spanish mountains have been affected by the expansion of shrubs and forests since the mid‐20th century. This secondary succession in vegetation has some positive effects, but also drawbacks, such as an increase in fire risk, loss of diversity in land use, a reduction in landscape and cultural value, less water available in river channels and reservoirs, constraints on livestock farming, a reduced number of local species and loss of biodiversity.

Savanna fire regimes assessment with MODIS fire data: Their relationship to land cover and plant species distribution in western Burkina Faso (West Africa)

Journal Articles & Books
Décembre, 2010
Burkina Faso

The West African savannas are subject to changes in fire regimes related to land use intensification, which may infer significant biological modifications. We investigated the efficiency of MODIS fire products to account for the variability of fire regimes in relation to changes in land cover and savanna vegetation. The specificity and complementarities of both MODIS active fire (MOD14A2 and MYD14A2) and burnt area (MCD45A1) products were assessed in order to characterize fire regimes and to relate them with land cover.
