The Climate Technology Centre welcomed Amis de l'Afrique Francophone from Benin (AMAF-Benin) as its 400th Network member. This global network is comprised of technology experts from civil society, finance, the private sector and research institutions around the world.
UN Environment has launched a web app and infographic to support people living and working on coasts in making decisions on how to adapt to a changing climate.
Rising populations and climate change are increasing sea level, storm intensity and rainfall. The Coastal Hazard Wheel can be used to consider how different coastal societies should respond.
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.
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.
Since 2003 the waste water from the town of Trosa (about 4500 citizens) has been treated in artificial wetlands, after the basic treatment in the sewage plant. Thanks to the wetlands the Trosa river and the town bay have been spared from eutrophicating substances (plant nutrients) as well as contagious substances (pathogenes). Besides the value of purifying the water, the wetlands are a popular recreation area. The wetlands are used for education and many study visits are made here.
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.
