Publication dateObjective
The conversion of wetlands to agriculture through drainage and flooding, and the burning of wetland areas for agriculture have important implications for greenhouse gas (GHG) production and changing carbon stocks. However, the estimation of net GHG changes from mitigation practices in agricultural wetlands is complex compared to dryland crops. Agricultural wetlands have more complicated carbon and nitrogen cycles with both above- and below-ground processes and export of carbon via vertical and horizontal movement of water through the wetland.

Objective
The largest and northern most full-scale system for wastewater irrigation of Salix plantations in Sweden.
The local community in Hedemora has long experience in producing biofuel from Salix plantations. The cooperation between Hedemora Energi AB and local farmers has resulted in irrigation of 75 acres of Salix Plantations. The local farmers in the project are guaranteed to sell their biofuel to the local municipal heating plant. As a result the project is contributing to the local production and consumption. -

Poor people living in hazardous and unhealthy environments in urban areas may find their difficulties compounded by the consequences of climate change. These include those who construct their shelters on steep, unstable hillsides, or along the foreshore on former mangrove swamps or tidal flats.

This report outlines lessons learnt regarding the principal effects of climate change on 15 cities in low-income countries, and what makes them vulnerable to these effects. It notes that coastal cities are mostly located in tropical areas with hot and humid climates and low-lying land.

This paper summarises the importance of wetlands in relation to climate change and eaxmines their potential role in the measures for Reducing Emissions from Deforestation and Forest Degradation (REDD) under the Kyoto Protocol. The links between REDD concepts and wetlands are explored for the following reasons:

This article analyses factors that contribute to the livelihood of smallholder farmers living near the Cyabayaga and Rugeramigoziwetlands. Three tools were used: focus group discussion, formal surveys and Monitoring for Quality Improvement (MONQI). Farming systems in wetlands and on hillsides differ. Level of education, resource availability, land ownership and location have important impacts on the location and type of farming systems practised by households. The dependency of households on wetlands varies between sites.

An artificial wetland was built in the spring of 2006 next to the lake Myrsjön in Nacka. The aim is to use nature’s own mechanisms to clean the polluted storm water from an industrial area, before it runs into the lake Myrsjön.

ObjectiveTechnology
Törnebybäcken, a stream which drains most of the Kalmar countryside just west of Kalmar, is one of the municipality's most nutrient-loaded water bodies. Kalmar airport contributes to the supply of mainly nitrogen that is used to keep the runways unfrozen. Through a unique partnership between CAA and Kalmar municipality, a large proportion of mainly nitrogen, but also phosphorus that would otherwise be added to the West Lake (a bay of the Baltic Sea), are deleted in the landscaped wetland park Kalmar Dämme.
