relationships between land cover, climate and cave copepod spatial distribution and suitability along the Carpathians

Journal Articles & Books
Décembre, 2014

The distribution of subterranean copepods may reflect the persistence of cave assemblages in relation to the environmental health of the overlying landscape. Areas supporting groundwater fauna were established by modelling the persistence of seven copepod species using a geographical information system (GIS). Environmental drivers were found to influence subterranean copepod distribution in the caves of the Romanian Carpathians.

Migrants, land markets and carbon emissions in Jambi, Indonesia: Land tenure change and the prospect of emission reduction

Policies designed to reduce land-based carbon emissions require a good understanding of the complex connections between state-sanctioned concessions, forest conversion, informal land markets and migrants. Our case study in the peat forests of the Tanjung Jabung Barat (TanJaBar) regency of Jambi, Indonesia aimed to explore relations between four key stakeholder groups: the state, local communities, migrants, and state-sanctioned concessions.

Implications of uncertainty and scale in carbon emission estimates on locally appropriate designs to reduce emissions from deforestation and degradation (REDD+)

Journal Articles & Books
Décembre, 2014
Indonésie

This study combined uncertainty analysis of carbon emissions with local stakeholders' perspectives to develop an effective Reducing Emission from Deforestation and Degradation (REDD+) scheme at the district level. Uncertainty of carbon emission estimates depends on scale while local stakeholders' views on plausible REDD+ schemes influence and limit transaction costs. The uncertainty analysis formed the basis for determining an appropriate scale for monitoring carbon emission estimates as performance measures for REDD+ incentives.

Reform or reversal: the impact of REDD+ readiness on forest governance in Indonesia

Indonesia has turned its alleged role as global leader of land-based carbon emissions into a role as a global trailblazer exploring modalities for Reducing Emissions from Deforestation and Forest Degradation (REDD+). REDD+ readiness is largely about improving forest governance, but this itself is a multilayered concept. This article analyses how the processes and practices of REDD+ readiness are leading to various forest governance reforms in Indonesia.

framework for national assessment of land degradation in the drylands: a case study of somalia

Land degradation is a gradual, negative environmental process that is accelerated by human activities. Its gradual nature allows degradation to proceed unnoticed, thus reducing the likelihood of appropriate and timely control action. Presently, there are few practical frameworks to help countries design national strategies and policies for its control. The study presented here developed a framework for the national assessment of land degradation. This framework is envisaged to support governments in formulating policies on land degradation.

Still a one species genus? Strong genetic diversification in the world’s largest living odonate, the Neotropical damselfly Megaloprepus caerulatus

Journal Articles & Books
Décembre, 2014

Mesoamerican biodiversity is increasingly threatened by anthropogenic destruction of natural land cover. Habitat degradation and climate change are primary threats to specialized forest odonate species that are important model organisms for forest health and defining conservation units. The extreme niche specialization of Megaloprepus caerulatus, the world’s largest extant odonate, makes it well suited as an indicator for changing environmental conditions.

implications of a changing climate on agricultural land classification in England and Wales

Journal Articles & Books
Décembre, 2014

The agricultural land classification (ALC) of England and Wales is a formal method of assessing the quality of agricultural land and guiding future land use. It assesses several soil, site and climate criteria and classifies land according to whichever is the most limiting. A common approach is required for calculating the necessary agroclimatic parameters over time in order to determine the effects of changes in the climate on land grading.

Aeolian processes and landscape change under human disturbances on the Sonid grassland of inner Mongolian Plateau, northern China

Chine

Based on remote sensing monitoring, observations and experiments in wind tunnel and field, aeolian processes and landscape change of the Sonid grassland of Inner Mongolia Plateau in northern China were explored in this paper. Aeolian process was very strong and seriously affected by human disturbances on the Sonid grassland of Inner Mongolia Plateau. Sand transport rate of grassland increased quickly with the increase of desertification severities, especially at the very severe desertification stage of sand sheet emergence.

Mercury proxies and mercury dynamics in a forested watershed of the US Northeast

Journal Articles & Books
Décembre, 2014

Although many studies focus on mercury (Hg) and methylmercury (MeHg) dynamics in streams, challenges remain in identifying the relative importance of land cover and seasonality at regulating Hg and MeHg dynamics at the watershed scale. Developing robust proxies for Hg and/or MeHg determination also remains a challenge. Our study used Hg, MeHg, and dissolved organic carbon (DOC) concentration measurements and various DOC fluorescence indices to characterize Hg and DOC dynamics in a forested watershed of the US Northeast.

Does Forest Expansion Mitigate the Risk of Desertification? Exploring Soil Degradation and Land-Use Changes in a Mediterranean Country

Italie

SUMMARY The present study evaluates the vulnerability to soil degradation of four land-use classes (urban areas, cropland, forests and non-forest natural land) during 1960–2010 using the Environmental Sensitive Area Index (ESAI) to verify if forests mitigate the increase of desertification risk in Italy. Results indicate that forests was the class with the lowest level of vulnerability during the whole investigated period and with the growth rate (1960–2010) in the ESAI always below the one observed on a landscape scale.

Land degradation in dolj county, southern romania: environmental changes, impacts and responses

Europe orientale

Central and Eastern Europe is experiencing significant land degradation, at the same time as social, economic and political transformation, and within the broader context of global climate change. This paper uses satellite data, primary field data and secondary information on Romania's social, political and economic dynamics, in a mixed‐method case study analysis of the drivers of, and responses to, environmental change and land degradation over the period 1984–2007.

Global drivers setting desertification research priorities: insights from a stakeholder consultation forum

Recent rapid changes in global scale drivers of desertification, land degradation and drought (DLDD) have two important consequences for drylands. First, changes in these drivers, for example in food and energy prices, make improving interventions in drylands more urgent because of their potential impacts. Second, these changes introduce new knowledge gaps regarding both the potential impacts on social‐ecological dryland systems and the design of options to take advantage of opportunities.
