Multiple site tower flux and remote sensing comparisons of tropical forest dynamics in Monsoon Asia

Journal Articles & Books
December, 2008

The spatial and temporal dynamics of tropical forest functioning are poorly understood, partly attributed to a weak seasonality and high tree species diversity at the landscape scale. Recent neotropical rainforest studies with local tower flux measurements have revealed strong seasonal carbon fluxes that follow the availability of sunlight in intact forests, while in areas of forest disturbance, carbon fluxes more closely tracked seasonal water availability.

hidden nature of parent material in soils of Italian mountain ecosystems

Italy

Soils with andic features are known to be very important as regards both ecosystem fertility and susceptibility to land degradation. In recent years there has been an increasing number of finds of these soils in non-volcanic mountain ecosystems (NVME) in different parts of the world under different environmental settings. In Italian NVME there has been extensive investigation proving that these soils have a much wider distribution than previously thought. But despite these important findings, very little is known about their genesis or properties.

Land Degradation Analysis on Coastal Area of Ampara District

Journal Articles & Books
October, 2013
Sri Lanka

The island of Sri Lanka is free from serious natural hazards such as volcanic activity and earthquakes resulting from climatic extremes, but there are impacts of many natural disasters, such as landslides, floods and droughts, the intensity and frequency of which are increasing due to human interventions. Some areas of Sri Lanka are also periodically subject to cyclones that occur due to climatic conditions and geographical locations.Land degradation denotes all natural or anthropogenic processes that diminish or impair productivity of land.

Grazing as a post-mining land use: A conceptual model of the risk factors

Australia

Driven principally by government regulation and societal expectations, mining companies around the world are seeking to mitigate the environmental impacts of mining through mined land rehabilitation programs. The ultimate goal of rehabilitation is to establish an acceptable and sustainable post-mining land use. Mining companies worldwide face the challenge of specifying just what a sustainable post-mining land use will be.

Impact of terrain attributes, parent material and soil types on gully erosion

Southern Africa

Gully erosion is a worldwide matter of concern because of the irreversible losses of fertile land, which often have severe environmental, economic and social consequences. While most of the studies on the gullying process have investigated the involved mechanisms (either overland flow incision, seepage or piping erosion), only few have been conducted on the controlling factors of gully wall retreat, an important, if not the dominant, land degradation process and sediment source in river systems.

Reconstruction of Holocene environmental changes in two archaeological sites of Calabria (Southern Italy) using an integrated pedological and anthracological approach

Journal Articles & Books
December, 2013
Italy

This paper focuses on the reconstruction of Holocene climatic and environmental changes in two archaeological sites of southwestern and north-central Calabria (southern Italy). It is based on a comparison of geoarchaeological, pedological and pedoanthracological data from soil profiles in the coastal hilly and inland mountainous surroundings of Palmi and Cecita Lake, respectively. At the Palmi site, the representative soil profile includes settlements and artefacts ranging from late Neolithic to late early Bronze Age and undifferentiated historical epochs.

Lignin signature as a function of land abandonment and erosion in dry luvisols of SE Spain

Journal Articles & Books
December, 2012

This study addressed long-term land degradation and regeneration effects on soil organic carbon (SOC) composition. This was done in a context of secondary succession following land abandonment in the Mediterranean region of SE Spain. The effects of land use change and soil erosion on SOC composition were studied by using lignin as a biomarker. To get insight into the evolution of SOC composition along a land use and topographical gradient, differences in lignin contribution to SOC were determined at different soil depths (0–0.1m, 0.1–0.2m, 0.2–0.3m).

Water Resources and Soil Management In Italy

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.

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

Journal Articles & Books
December, 2014
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.

Shieling Areas: Historical Grazing Pressures and Landscape Responses in Northern Iceland

Journal Articles & Books

Iceland

Historical domestic livestock grazing in sensitive landscapes has commonly been regarded as a major cause of land degradation in Iceland. Shieling areas, where milking livestock were taken to pasture for the summer, represented one element of grazing management and in this paper we consider the extent to which historical shieling-based grazing pressure contributed to land degradation.

Impacts of innovative forestry land use on rural livelihood in a bimodal agricultural system in irrigated drylands

Central Asia

The conversion of marginal croplands to tree plantations, as an option to address climate change, land degradation, and irrigation water scarcity, as well as to improve the welfare of local population requires prior analysis.
