Effects of land use, land cover and rainfall regimes on the surface runoff and soil loss on karst slopes in southwest China

Journal Articles & Books
Décembre, 2012
Chine

Surface runoff and soil loss from 2007 to 2010 related to land use and rainfall regimes in karst hill slopes in Guizhou Province, southwest China, were analyzed. Using the hierarchical clustering method, sixty-one rainfall events under the subtropical monsoon climate condition were classified into 5 types of rainfall regimes according to the depth, maximum 30-min intensity, and duration of rainfall.

Modelling landscape complexity for land use management in Rio de Janeiro, Brazil

Journal Articles & Books
Décembre, 2012
Brésil

Prioritizing land units for environmental management and planning is central in any process aiming at the improvement of urban and environmental conditions. In this study, an algebraic method (lattice theory) was applied to data describing the characteristics of ten land units of a landscape of Rio de Janeiro, Brazil. Consequently, landscape complexity was modeled and land units were prioritized for land management.

GIS and the ‘Usual Suspects’-[Mis]understanding Land Use Change in Cambodia

Journal Articles & Books
Décembre, 2014
Cambodge

GIS-RS techniques offer great potential for providing insights into the spatiality and temporality of the messy realties of deforestation. However, rather than positing that the land use maps produced using these novel technologies can cut through politics, it is argued that the map is merely an artifact of the broader process of land use planning which is constitutive of politics. This article critically reflects on a major land use mapping exercise that the two authors were involved with, in central Cambodia.

Determination of time effect on change of recreational tendencies: recreation area of Kafkasör Forest, Artvin

Policy Papers & Briefs
Décembre, 2009
Turquie

Kafkasör Forest Area which is close to the Artvin (Turkey) city center is an important recreational area. 'Kafkasör Festival' is arranged in July every year. However, the area is intensively used during the festivals, and irregular usage and lack of equipment damage the area. Because of the intensity of festival activities, the area can not respond the needs and the determined visitor necessities don't be used in planning. Hence, redefining the visitor demand should be determined.

Crowdsourcing indicators for cultural ecosystem services: A geographically weighted approach for mountain landscapes

Journal Articles & Books
Décembre, 2016

Integrating cultural dimensions into the ecosystem service framework is essential for appraising non-material benefits stemming from different human–environment interactions. This study investigates how the actual provision of cultural services is distributed across the landscape according to spatially varying relationships. The final aim was to analyse how landscape settings are associated to people's preferences and perceptions related to cultural ecosystem services in mountain landscapes.

Probability maps of landslide reactivation derived from tree-ring records: Pra Bellon landslide, southern French Alps

Journal Articles & Books
Décembre, 2012

Probability maps of landslide reactivation are presented for the Pra Bellon landslide located in the southern French Alps based on results obtained with dendrogeomorphic analysis. Spatiotemporal patterns of past landslide activity was derived from tree-ring series of 403 disturbed mountain pine trees growing in the landslide body. In total, 704 growth disturbances were identified in the samples indicating 22 reactivation phases of the landslide body between 1910 and 2011. The mean return period was 4.5years.

Evaluating the relative impact of climate and economic changes on forest and agricultural ecosystem services in mountain regions

Journal Articles & Books
Décembre, 2013
Suisse

Provisioning of ecosystem services (ES) in mountainous regions is predicted to be influenced by i) the direct biophysical impacts of climate change, ii) climate mediated land use change, and iii) socioeconomic driven changes in land use. The relative importance and the spatial distribution of these factors on forest and agricultural derived ES, however, is unclear, making the implementation of ES management schemes difficult.

Assessing humification and organic C compounds by laser-induced fluorescence and FTIR spectroscopies under conventional and no-till management in Brazilian Oxisols

Journal Articles & Books
Décembre, 2013
Brésil

Data on humification is important to assessing the rate and magnitude of soil carbon (C) sequestration. Thus, this study assessed the humification degree (HLIF) of soil organic matter (SOM) and the changes in functional C groups (aromatic-C and aliphatic-C) for contrasting land use and management practices (native vegetation (NV), conventional plow-based tillage (CT) and no-till (NT) systems) in sub-tropical and tropical Brazilian environments. Experiments were conducted at Ponta Grossa (PG) in Paraná State and Lucas do Rio Verde (LRV) in Mato Grosso State of Brazil.

Land use, rangeland degradation and ecological changes in the southern Kalahari, Botswana

Journal Articles & Books
Décembre, 2016
Botswana

Dual‐scale analyses assessing farm‐scale patterns of ecological change and landscape‐scale patterns of change in vegetation cover and animal distribution are presented from ecological transect studies away from waterpoints, regional remotely sensed analysis of vegetation cover and animal numbers across the southern Kalahari, Botswana. Bush encroachment is prevalent in semi‐arid sites where Acacia mellifera Benth. is widespread in communal areas and private ranches, showing that land tenure changes over the last 40 years have not avoided rangeland degradation.

Assessment of geo-hazards in a rapidly changing landscape: the three Gorges Reservoir Region in China

Journal Articles & Books
Décembre, 2015
Chine

Large dam projects attract worldwide scientific attention due to their environmental impacts and socioeconomic consequences. One prominent example is the Three Gorges Dam (TGD) at the Yangtze River in China. Due to considerable resettlements, large-scale expansion of infrastructure and shifts in land use and management, the TGD project has irreversible impacts on the Upper Yangtze River Basin and strongly challenges the environmental conditions of this fast-developing region. Soil erosion and landslides are major geo-hazards.
