evolution of the timber sector in lowland Bolivia: Examining the influence of three disparate policy approaches

Journal Articles & Books
Diciembre, 2010
Bolivia

This paper assesses the influence of forest policies on forestry development, and especially timber production, in Bolivia during three different periods of time. The first period began in the early 1970s when a conservative forest policy was adopted privileging commercial logging companies, and thus fueling land conflicts in particular with indigenous people, allowing a minority to accumulate considerable wealth, and marking the onset of forest degradation.

Stability evaluation of the number of farmers farms and declared agricultural land in Lithuania

Conference Papers & Reports
Diciembre, 2016
Letonia
Lituania

The beginning of the restitutional land reallocation reform in 1991 brought a rapid change in agricultural land utilisation and user groups resulting in the decrease of state land users’ categories and the growth of private agricultural land areas used by farmers and other natural and legal entities. The aim of the article is to analyse the stability of farmers farms and their agricultural areas in Lithuania during the period between 2009 and 2014.

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

Journal Articles & Books
Diciembre, 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

Journal Articles & Books

España

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
Diciembre, 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.

Effect of Urban Expansion on Urban Surface Temperature in Shenyang, China: an Analysis with Landsat Imagery

Journal Articles & Books
Diciembre, 2015
China

Landsat Thematic Mapper (TM)/Enhanced Thematic Mapper Plus (ETM+) images were used to assess the urban expansion dynamics and the corresponding thermal characteristics in Shenyang City, China. Unsupervised classification (ISODATA) and a hierarchy decision tree were applied to eight scenes of the Landsat images to derive the land use/land cover (LULC) around the Shenyang metropolitan region from 1986 to 2007.

Role of state administration in updating land-estate and farm-size conditions

Conference Papers & Reports
Diciembre, 2007

The structure of land estates and farm-sizes are the basis of a competitive agricultural production, hence these questions belong to the evergreen themes both of theory and practice also on international level. In Central and Eastern European Countries (CEECs), the change ofpolitical and economic regime virtually tore into the agriculture in beginning of 1990s, destroying the existing structure of land estates by the privatization, restitutions or restoration of ownership rights resulting in fragmentation of land ownership.

Using a groundwater quality negotiation support system to change land-use management near a drinking-water abstraction in the Netherlands

Journal Articles & Books
Diciembre, 2008
Países Bajos

A negotiation support system (NSS) was developed to solve groundwater conflicts that arose during land-use management. It was set up in cooperation with the stakeholders involved to provide information on the impact of land use, e.g., agriculture, nature (forested areas), recreation, and urban areas, on the quality of both infiltrating and abstracted groundwater. This NSS combined simulation programs that calculate (1) the concentrations of nitrate in shallow groundwater for each land-use area and (2) the transport of nitrate in the groundwater-saturated zone.

Assessing the benefits and costs of dryland forest restoration in central Chile

Journal Articles & Books
Diciembre, 2012
Chile

Investment in natural capital restoration is increasing as a response to the widespread ecological degradation of dryland forests. However, finding efficient mechanisms to promote restoration among private landowners is a significant challenge for policy makers with limited financial resources. Furthermore, few attempts have been made to evaluate the costs and benefits of restoration interventions even though this information is relevant to orient decision making.

Habitat selection in a changing environment: the relationship between habitat alteration and Scops Owl (Aves: Strigidae) territory occupancy

Journal Articles & Books
Diciembre, 2013
Italia

The Scops Owl Otus scops (L., 1758) is a species of European concern, which suffered a noticeable decrease in distribution in the last decades, and changes in agricultural practices have been proposed as a major threat for this owl. We studied the habitat preference of the Scops Owl by assessing the habitat occupancy of 401 territories distributed in a large area in northwest Italy, with a special focus on 98 territories located in a high-density area (Monferrato).
