Baseline choice and performance implications for REDD

Journal Articles & Books
december, 2016

Reducing Emissions from Deforestation and forest Degradation (REDD) projects are being designed and implemented across tropical countries, intending to curb the contribution of deforestation to greenhouse gas emissions. An important aspect of REDD implementation is the baseline against which reductions are measured. The baseline estimates the business-as-usual emissions from deforestation and forest degradation. We solve a dynamic model of land conversion from forest to agriculture in the presence of REDD, and assess the performance of four baselines.

Multitemporal Monitoring of Land Degradation Risk Due to Soil Loss in a Fire-Prone Mediterranean Landscape Using Multi-decadal Landsat Imagery

Journal Articles & Books
december, 2016

Natural, as well as human-induced, landscape changes may have profound effects on soil-loss rates in Mediterranean countries. Knowledge of the spatial and temporal distribution of the erosion processes from 1984 to 2013 across the fire-prone island of Thassos was gained on the basis of a joint analysis of imagery received from three generations of Landsat satellites. Soil loss was modeled using the revised universal soil loss equation.

Regional modeling of large wildfires under current and potential future climates in Colorado and Wyoming, USA

Regional analysis of large wildfire potential given climate change scenarios is crucial to understanding areas most at risk in the future, yet wildfire models are not often developed and tested at this spatial scale. We fit three historical climate suitability models for large wildfires (i.e. ≥ 400 ha) in Colorado and Wyoming using topography and decadal climate averages corresponding to wildfire occurrence at the same temporal scale. The historical models classified points of known large wildfire occurrence with high accuracies.

Reconciling Flexibility and Tenure Security for Pastoral Resources: the Geography of Transhumance Networks in Eastern Senegal

Africa

The need to maintain or increase livestock mobility in arid Africa has been widely embraced by ecologists, social scientists, and more recently regional governments. These movements are seen to sustain livestock production under a highly variable and changing climate. At the same time, livestock mobility is threatened by the expansion of agriculture onto rangelands.

Water Resources and Soil Management In Italy

Journal Articles & Books

Italy

Italy has always had a long dramatic history of extreme events such as landslides, flooding, land degradation and drought. Much has been done in terms of prevention and monitoring but still there is much left to do, in particular introducing innovative alert systems based on the integration of real‐time weather forecasting with national alert and protection systems.

European scale analysis of phospholipid fatty acid composition of soils to establish operating ranges

Journal Articles & Books
december, 2016

Recent preoccupations regarding possible negative effects of pollution, inappropriate land management, climate change, desertification, erosion, compaction or over-exploitation on soils has led to initiatives for the survey of soils. One of them, EcoFINDERS, launched a pan-European survey in order to define normal operating ranges for soil biodiversity and quality, through the use of several methodologies.

Prediction of blanket peat erosion across Great Britain under environmental change

Journal Articles & Books
december, 2016

A recently developed fluvial erosion model for blanket peatlands, PESERA-PEAT, was applied at ten sites across Great Britain to predict the response of blanket peat erosion to environmental change. Climate change to 2099 was derived from seven UKCP09 future projections and the UK Met Office’s historical dataset. Land management scenarios were established based on outputs from earlier published investigations. Modelling results suggested that as climate changes, the response of blanket peat erosion will be spatially very variable across Great Britain.

Three‐dimensional structure and cyanobacterial activity within a desert biological soil crust

Journal Articles & Books
december, 2016

Desert biological soil crusts (BSCs) are formed by adhesion of soil particles to polysaccharides excreted by filamentous cyanobacteria, the pioneers and main producers in this habitat. Biological soil crust destruction is a central factor leading to land degradation and desertification. We study the effect of BSC structure on cyanobacterial activity. Micro‐scale structural analysis using X‐ray microtomography revealed a vesiculated layer 1.5–2.5 mm beneath the surface in close proximity to the cyanobacterial location.

Assessing the effects of long-term recreational activities on landscape changes in Abant Natural Park, Turkey

Turkey

Natural, protected areas offer many possibilities for recreation in rural areas such as camping, one of the most popular activities. The system established for protected areas in Turkey aims to provide a foundation for conserving areas for recreation. One such area, Abant Natural Park, is convenient for visits from Turkey’s two most populated metropolitan areas, Istanbul and Ankara. It also attracts tourists from other regions and countries.

Impact of land use intensity on sandy desertification: An evidence from Horqin Sandy Land, China

Journal Articles & Books

China

It has been widely accepted that high land use intensity contributes to sandy desertification in Northern China. However, it is surprising that it is even not easy to find an explicit definition and proper indicator for the term “land use intensity” in the sandy desertification related literatures.

Spatio-temporal distribution pattern of vegetation coverage in Junggar Basin, Xinjiang

Journal Articles & Books
december, 2016

Vegetation coverage is an indicator used for exploring the growth of vegetation, which has attracted attention from ecologists owing to its significant role in ecological conservation and restoration. As an important component of the terrestrial ecosystem, changes in vegetation coverage reflect changes in the environment, especially with respect to arid areas. A change of vegetation coverage will trigger desertification, degradation of the eco-environment, and regional climate change.

Land degradation due to erosion in public perception. Case study: Secaşul Mare river basin settlements (Transylvanian Depression, Romania)

Romania

According to the International Decade for Natural Disaster Reduction (IDNDR 1990–1999), the risk indicates potential losses due to particular natural phenomenon, and these could be reduced by improving of prevention and education. People perceive these losses differently depending on phenomenon occurrence, severity, and impact in time. Starting from this idea, this research presents public perception on land degradation through erosion in a small area from the central part of Romania (south-west of Transylvanian Depression).
