Landscape Maintenance and Farming in the Alps: From Family Firms Up-Keeping to Inter-Institutional Arrangements

Conference Papers & Reports
Diciembre, 2005

This contribution discusses assets and limits of the local/territorial level as a core level to improve the sustainability of agriculture. The focus is on the issue of rural landscape maintenance through farming. Some possible institutional solutions to overcome the difficulties of family farms are examined. New institutional settings such as the "local group", constituting an interface for the negotiation among different local stakeholders, seem to effectively facilitate the stipulation of local contracts for landscape management.

Land suitability evaluation for development using a matter-element model: A case study in Zengcheng, Guangzhou, China

Journal Articles & Books
Diciembre, 2012
China

Land suitability evaluation can assist in the efficient use of land resources at a regional level. This is an important issue because of the pressures that an increasing population and economic growth have put on limited land resources. Matter-element theory, which was first put forward by the Chinese mathematician Cai Wen, has shown potential for solving incompatibility problems.

Soil erosion risk assessment with CORINE model: case study in the Danjiangkou Reservoir region, China

Journal Articles & Books
Diciembre, 2012
China

Soil erosion is one of the major threats to the conservation of soil and water resources in the Danjiangkou Reservoir region (DRR), China. In order to describe the areas with high soil erosion risk (SER) and to develop adequate erosion prevention measures, SER in the DRR was assessed by integrating the CORINE model with GIS and RS.

Horse riding posing challenges to the Swedish Right of Public Access

Suecia

Increasing numbers of horses are being kept for sports and leisure purposes in peri-urban areas throughout the Western world. This expansion of the equestrian sector represents a multifunctional transition, with new production of rural goods and services and increasing influence on land use. In Sweden, the number of horses has increased from 70,000 to approximately 300,000 over the last 30 years. This increase is putting pressure on the traditional Right of Public Access, an old custom allowing the public to walk, cycle or ride on private or state-owned property.

Ecological classification of land and conservation of biodiversity at the national level: The case of Italy

Journal Articles & Books
Diciembre, 2012
Italia

The aims of this study are to describe the ecological classification of land in Italy and to show how the resulting land units can act as reliable frameworks for coarse scale environmental analyses that can be used to implement national conservation strategies. We first collected, homogenised and drew physical thematic maps, which were then linked to biological and human features. We then performed a gap analysis of land heterogeneity compared with Natural Protected Areas and Natura2000 network on the basis of three categories: Total gaps, Partial gaps, and Protected.

Effects of spatial extent on landscape structure and sediment metal concentration relationships in small estuarine systems of the United States' Mid-Atlantic Coast

Journal Articles & Books
Diciembre, 2008
Estados Unidos de América

Prior studies exploring the quantitative relationship between landscape structure metrics and the ecological condition of receiving waters have used a variety of sampling units (e.g., a watershed, or a buffer around a sampling station) at a variety of spatial scales to generate landscape metrics resulting in little consensus on which scales best describe land-water relationships. Additionally, the majority of these studies have focused on freshwater systems and it is not clear whether results are transferable to estuarine and marine systems.

Potential links between rural tourism and agriculture in the Northern Great Plain Region

Journal Articles & Books
Diciembre, 2009
Hungría

Agriculture has played and still plays a significant role in the life of rural communities and in rural development. But, because agriculture yields low revenues, agricultural workers often need a source of additional income. Agriculture combines excellently with the growing of medicinal herbs, organic farming, handicrafts and tourism. Rural tourism, as originally conceived, is a source of revenue to supplement income from agriculture.

Land cover mapping of the tropical savanna region in Brazil

Brasil

The Brazilian tropical savanna (Cerrado), encompassing more than 204 million hectares in the central part of the country, is the second richest biome in Brazil in terms of biodiversity and presents high land use pressure. The objective of this study was to map the land cover of the Cerrado biome based on the segmentation and visual interpretation of 170 Landsat Enhanced Thematic Mapper Plus satellite scenes acquired in 2002. The following land cover classes were discriminated: grasslands, shrublands, forestlands, croplands, pasturelands, reforestations, urban areas, and mining areas.

conceptual framework to analyse the land-use/land-cover changes and its impact on phytodiversity: a case study of North Andaman Islands, India

Journal Articles & Books
Diciembre, 2010
India

Phytodiversity is affected both by natural and anthropogenic factors and in Island ecosystems these impacts can devastate or reduce diversity, if the native vegetation is lost. In addition to rich species richness and diversity, Island systems are the sites of high endemism and any threat to these ecosystems will consequently lead to loss and extinction of species.

Relationships between Danish organic farming and landscape composition

Journal Articles & Books
Diciembre, 2007
Dinamarca

This article presents an investigation of relationships between organic farming and landscape composition in Denmark. Landscape composition was analysed in terms of density of uncultivated landscape elements (I), number of land uses per hectare (II), diversity of land use (III) and mean field size (IV). Two analytical approaches were used. The first was based on an examination of the national agricultural registers for 1998, 2001 and 2004.
