Phosphorus release and retention by soils of natural isolated wetlands
Hydrological restoration of historically isolated wetlands may mitigate phosphorus (P) loss. The objectives of this study were to quantify P in soil, and to determine the effect of (1) soil characteristics on P release, and (2) antecedent soil hydrological conditions on P dynamics. Humic/fulvic acid bound P and residual P accounted for majority of P (>78%) in surface soils. Soils with highest ...

Sizing mitigation wetlands in agricultural watersheds
In this study, we investigated use of microcosms to supplement field studies for establishing the size of wetlands required to mitigate nitrate pollution in agricultural watersheds. Wetlands investigated in this study were located in San Joaquin Valley (California, USA) and demonstrated mean nitrate-nitrogen mass removal efficiencies ranging between 10 and 34%. Mean areal nitrate removal ...

Community Vulnerability and Capacity Assessment in the Context of Disaster Risk Reduction
Indonesia is a country of multiple disasters. There are around 13 types of disaster that could occur at any time. More than 200 million of Indonesia’s inhabitants are exposed to the possibility of tsunami, with around 5 million living in tsunami-prone areas. Moreover, being located in the “Ring of Fire”, Indonesia also possesses about 400 volcanoes of which 100 are still active. ...

Guidelines for identifying business risks and opportunities arising from ecosystem change
Ecosystems provide businesses with numerous benefits or “ecosystem services.” Forests supply timber and wood fiber, purify water, regulate climate, and yield genetic resources. River systems provide freshwater, power, and recreation. Coastal wetlands filter waste, mitigate floods, and serve as nurseries for commercial fisheries. However, human activities are rapidly degrading these and other ...

A fuzzy quality index for the environmental assessment of a restored wetland
This paper describes the feasibility study for the restoration of agricultural land with a tendency to become waterlogged into a natural wetland, conceived to mitigate floods and to remove nutrients from the water drained from the cultivated plots. The wetland model, developed in aquatox, includes the nutrient dynamics both in the water and in the sediment, and the vegetation that is expected to ...

Asia Analysis: Battling climate impacts in low-lying Maldives
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 International Year of Small Island Developing States ...

Keep it Fresh or Salty - An introductory guide to financing wetland carbon programs and projects
Wetlands have been the focus of conservation and restoration efforts for over a century. A diverse portfolio of financing sources has been used for supporting such activities including philanthropy, multi- and bilateral aid, in-country governmental funding, tourismrelated and other usage fees, as well as fees and levies associated with wetlands-centric extractive industries (e.g. peat ...

Position Brief on oil and gas development of the Arctic
Background The Arctic Circle encompasses roughly 6% of the earth’s surface. Wetlands make up about 60% of the total Arctic land mass and are the predominant ecosystem, however they are not well defined or understood. Arctic wetlands provide a wide range of ecosystem services such as the maintenance of permafrost, hydrology and water quality. Arctic wetlands have the highest biological ...

Bankers, what are the risks of your peatland investments?
The world’s increasing demand for palm oil and pulp wood for paper production attracts the private sector to invest more and more in these businesses in Indonesia and Malaysia. But are banks, the creditors of these businesses, aware of the risks of their investments in palm oil and pulp wood plantations when these are developed on peatlands? Oil palm and pulp wood cultivation on peatlands ...

Hydroseeding for Transportation Projects
Hydroseeding has connections with most forms of transportation, including revegetation around highways, airports, and mass transit projects. It is even a part of water-related travel, if one considers work done on the grounds at marinas, shipping channels, and ports. Working on the Railroad One recent transportation-related hydroseeding project was for BNSF. That acronym might not be familiar ...
