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.

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

Chine

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.

Effect of land use types on stream water quality under seasonal variation and topographic characteristics in the Wei River basin, China

Chine

The effect of topographic characteristics of land uses on stream water quality must be addressed for a better understanding of the complex relationship between land use and stream water quality. In this study, Geographic Information System (GIS) and Pearson correlation analysis were used to determine whether there were relationship between land use types and stream water quality at the sub-basin scale in the Wei River basin, China, during the dry and rainy seasons in 2012.

Assessing the mitigation potential of forestry activities in a changing climate: A case study for Karnataka

Inde

The Clean Development Mechanism (CDM), Article 12 of the Kyoto Protocol allows Afforestation and Reforestation (A/R) projects as mitigation activities to offset the CO2 in the atmosphere whilst simultaneously seeking to ensure sustainable development for the host country. The Kyoto Protocol was ratified by the Government of India in August 2002 and one of India's objectives in acceding to the Protocol was to fulfil the prerequisites for implementation of projects under the CDM in accordance with national sustainable priorities.

Modelling the likely impact of healthy eating guidelines on agriculture in England and Wales

Conference Papers & Reports
Décembre, 2008

Household food consumption data is used to estimate likely changes in diet under healthy eating guidelines, and the consequences this would have on the agricultural sector in England and Wales. The first step entails imposing nutrient restrictions on food consumption following dietary recommendations.

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

Journal Articles & Books

Bolivie

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
Décembre, 2016
Lettonie
Lituanie

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
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.
