Subsidence of Peat Soils – Flooding Risk in South-East Asia

by Wetlands International  (Jun. 16, 2014)

There is an increase in awareness of the carbon emissions resulting from peatland drainage and peat fires. There is in general however a lack of recognition link between carbon loss and peatland subsidence, i.e. lowering of the soil surface. In the tropics the process of subsidence after drainage is very fast due to high temperatures. Flood risks ...

Asia Analysis: Battling climate impacts in low-lying Maldives

by SciDev.Net  (Jun. 3, 2014)

Going carbon neutral and protecting marine environment are key to fighting climate change in the tiny island nation, says Nalaka Gunawardene. ‘Raise your voice, not the sea level’ is the theme for this year’s World Environment Day, which falls on 5 June. The theme resonates with the United Nations designating 2014 as the ...

Geographic information system-coupling sediment delivery distributed modeling based on observed data

by IWA Publishing  (Aug. 7, 2014)

Spatially distributed sediment delivery (SEDD) models are of great interest in estimating the expected effect of changes on soil erosion and sediment yield. However, they can only be applied if the model can be calibrated using observed data. This paper presents a geographic information system (GIS)-based method to calculate the sediment ...

Benefits of minimum tillage case study

by Syngenta  (Jun. 23, 2014)

In Hungary, the MARGINS project is being conducted near Lake Balaton - the largest lake in Central Europe. The lake is renowned for its beauty and wildlife. Its surrounding hilly landscape is covered with rich brown forest soil. This landscape is, however, prone to soil erosion -in particular, rills develop when soil is weakened by excessive ...

Secutex sandcontainers save Bridge Cãteasca case study

by NAUE GmbH & Co.KG  (Aug. 8, 2014)

As a result of the extreme rainfalls that occurred in Romania during the year 2005, many rivers had a significantly increase in water flow. One immediate consequence was that almost all the important rivers caused heavy floods with severe damage to civil structures and infrastructure. Another consequence with long term effects was that the ...

Have Your Steak and Eat It, Too

by Ensia  (Jul. 30, 2014)

In our recent feature, “Has Meat Met Its Match?,” writer Rowan Jacobsen explores ways people can (now and possibly in the future) reduce the environmental and food security impacts of their diets, including entomophagy (bug-eating), synthetic meat and vegetarian substitutes. If none of those fits your needs, there are plenty of other ...

How mangroves help in reducing flooding and coastal erosion

by Wetlands International  (Nov. 13, 2013)

Inhabitants of low lying delta areas are particularly exposed to flooding and erosion caused by storms and hurricanes. These pressures increase with climate change and sea level rise. Coastal wetlands, such as mangroves, can play a key role in damage mitigation during disasters, as well as in stabilising coastlines. They also contribute to ...

A sustainable solution for massive coastal erosion in Central Java - Towards Regional Scale Application of Hybrid Engineering

by Wetlands International  (Feb. 1, 2014)

Deltaic populations in western Indonesia are increasingly threatened by rapid shoreline degradation and erosion. In just a few decades, some coastal areas have retreated by more than two kilometres1. Housing, roads and valuable land is literally swept into the sea. This loss of land continues unabated, sometimes by tens of metres per year. The ...

Telejaen river, Romania case study

by NAUE GmbH & Co.KG  (Aug. 8, 2014)

The area around the North of Bucharest is heavily industrialised with oil extraction and preparation facilities. Therefore the railway network is well developed in the region, since the oil needs to be transported from here across the country. Teleajen is a small tributary of the Prahova river, that flows east of Ploiesti and crosses the railway ...

A sheet erodibility parameter for water erosion modeling in regions with low intensity rain

by IWA Publishing  (Nov. 20, 2013)

Soil erodibility reflects the soil effect on the detachment process by rainfall and runoff; an evaluation of this parameter for single storm events was carried out using natural runoff plot data collected for two rainfall seasons in northern Iraq. The region is characterized by a semiarid Mediterranean-type climate with normal rainfall intensity ...
