Spatial prediction of landslide hazards in Hoa Binh province (Vietnam): A comparative assessment of the efficacy of evidential belief functions and fuzzy logic models

Journal Articles & Books
Décembre, 2012
Viet Nam

The main objective of this study is to evaluate and compare the results of evidential belief functions and fuzzy logic models for spatial prediction of landslide hazards in the Hoa Binh province of Vietnam, using geographic information systems. First, a landslide inventory map showing the locations of 118 landslides that have occurred during the last ten years was constructed using data from various sources.

Challenges and opportunities in linking carbon sequestration, livelihoods and ecosystem service provision in drylands

Journal Articles & Books
Décembre, 2012
Afrique

Changes in land use and management practices to store and sequester carbon are becoming integral to global efforts that both address climate change and alleviate poverty. Knowledge and evidence gaps nevertheless abound. This paper analyses the most pressing deficiencies in understanding carbon storage in both soils and above ground biomass and the related social and economic challenges associated with carbon sequestration projects.

Airports offer unrealized potential for alternative energy production

Journal Articles & Books
Décembre, 2012

Scaling up for alternative energy such as solar, wind, and biofuel raises a number of environmental issues, notably changes in land use and adverse effects on wildlife. Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limitations to establishing alternative energy production at airports, such as ensuring these facilities do not create wildlife attractants or other hazards.

Protected areas do not fulfil the wintering habitat needs of the trans-Saharan migratory Montagu’s harrier

Afrique

Populations of migratory birds can be affected by events happening at both breeding and wintering grounds. The Sahel is a vast region holding a large number of wintering trans-Saharan migratory European birds, and current land-use changes there may represent a threat for these species. We used satellite tracking data from the migratory Montagu’s harrier to evaluate habitat use of the species during the wintering season, and whether the current network of protected areas is effective to provide their habitat needs during that season.

Ecosystem service evaluation to support land-use policy

Journal Articles & Books
Décembre, 2012

Regular economic activity takes into account ecosystem goods and services that are exchanged for money in the market (e.g. food, fibre, water) but normally ignores more intangible ones left away from market transactions (e.g. soil protection, climate regulation, disturbance control, habitat provision), even in cases when they become irreversibly impaired.

Spatial complexity and ecosystem services in rural landscapes

Journal Articles & Books
Décembre, 2012

Despite general agreement on antagonist relationships between ecosystems capacity to simultaneously sustain the availability of regulating services and agricultural production, it is not clear how these tradeoffs operate in response to complexity loss at the rural landscapes level. Here we present a novel evaluation framework of ecosystem services (ES) and pose different response models to landscape complexity.

Temporal-spatial variability of desertification in an agro-pastoral transitional zone of northern Shaanxi Province, China

Journal Articles & Books
Décembre, 2012
Chine

Desertification has been widely treated as one of the major environmental hazards in the world by scientific communities and the public. Monitoring the dynamics and causes of desertification is essential to provide important instruction for desertification control strategies and rational planning of land use in arid and semi-arid areas.

Impact of the European Water Framework Directive on local-level water management: Case study Oxunda Catchment, Sweden

Journal Articles & Books
Décembre, 2012
Suède

The Water Framework Directive (WFD) of the European Union provides a common framework for water policy that focuses on holistic and integrated water management in river basins. In many member states, implementation of the WFD has shifted the main responsibility for local water issues from the municipal level to the regional or supra-regional levels. In this study, we investigated how the implementation of the WFD has influenced local-level water management including the interpretation of the new environmental quality standards.

How has Oregon's land use planning system affected property values?

Journal Articles & Books
Décembre, 2012

Oregon's landmark land use planning system has been criticized for imposing large negative effects on landowners’ property values, although evidence to support these claims has been lacking. This paper examines longitudinal data for undeveloped parcels since before adoption of the planning system. The sample includes parcels under different land use regulations, and it compares Oregon to Washington.

Using species distribution modeling to improve conservation and land use planning of Yunnan, China

Journal Articles & Books

Chine

Part of the Himalayan biodiversity hotspot, Yunnan province in China is a highly diverse terrestrial region, particularly in the wide range of natural forest types. These forests are under considerable conversion pressure as land use intensifies with expanding human population and economic development. Conservation strategies based on the geographic patterns of botanical species richness, including the identification of meaningful floristic regions and priority areas for conservation, could improve the effectiveness of forest policy and management.

Subsidence map of underground mining influence for urban planning: an example from the Czech Republic

Journal Articles & Books
Décembre, 2012
République tchèque

The objective of this study is to produce a subsidence map linked to underground mining influence in a mining region. Ground subsidence represents the most important characteristic of a subsidence basin. However, ground subsidence itself does not carry information on geohazards by means of the impacts on the built-up area. Based on long-term experience and studies carried out, three basic subsidence intervals of varying influence were proposed.

integrated spatial planning model for climate change adaptation in coastal zones

Taiwan

This research highlights the spatial planning approach for coastal sustainability and adaptation to climate change. The dilemma of spatial planning in a dynamic and complex coastal environment as well as the establishment of a coastal buffer zone as an adaptation measure for climate change are elaborated upon. In particular, this study outlines the limitations of two of the traditional approaches used for spatial planning (optimization and simulation) and the opportunities that present themselves when combining both models for coastal zone planning.
