All climate negotiations have been based on staying below 2°C above pre-industrial temperatures. Yet it looks increasingly unlikely that that will be possible. A new report, Turn Down the Heat: Why a 4°C Warmer World Must be Avoided, suggests that there is a 40 percent chance that we will reach 4°C by 2100 even if we stick to the agreed emission reduction commitments.
What does water look like in a 4°C world?
Put simply: it's complex. Water is a complicated system and one of the major impacts of climate change is the effect on the hydrological (water) cycle. These impacts will coincide with an unprecedented increase in demand for water because of population and economic growth.
They both hold the potential to help meet the needs of the poor and end poverty. New ideas and innovative solutions are critical to address the 2.5 billion people who lack access to proper sanitation. Lack of access to clean water and sanitation kills more than 4,000 children a day and a lack of sanitation results in billions of dollars in economic losses to developing countries. Now that more people have access to a mobile phone than to a toilet or latrine, it’s time to leverage technology to help reach development goals.
“Superstorm” Sandy passed through the northeast United States earlier this week. High winds and heavy rains caused considerable damage, particularly in New Jersey and New York. High winds damaged buildings and knocked down trees and branches. Falling trees and branches caused more damage, including falling on electrical and telephone wires, breaking them and causing widespread power outages. Further, the winds north of the storm’s center pushed already high tides into repeated surges, some as much as 4.5 m (over 13 feet) above normal high tide. Coastal areas, including parts of Manhattan, were submerged; road and subway tunnels filled with water. Heavy rains caused additional flooding along rivers and coastlines.
Thousands of water development practitioners have begun to descend upon Stockholm for World Water Week, the annual knowledge-sharing event hosted by the Stockholm International Water Institute. It was raining earlier today in Sweden’s capital. But some parts of the world have suffered through unprecedented high temperatures and drought. The drought in the US can be seen from space, as described in this Wired magazine article. This drought has led to damages to, and drops in, yields of crops of maize and soybeans, for which the US is the largest exporter in the world. It has also meant higher food prices.
... and the winner is an entry from the California Institute of Technology! Michael Hoffman received the prize for the "Reinvent the Toilet Challenge" from Bill Gates himself on August 14, 2012 in Seattle. The award winning technology model is based on a self-contained, sun-powered system that recycles water and breaks down human waste into storable energy.
It’s been almost 8 months since the World Bank Group convened the first Water Hackathon. The Water Hackathon brought nearly 1000 computer programmers in 10 cities around the world together to compete to build prototype solutions to challenges in water, including sanitation. We had worked to help governments, utilities, civil society groups, World Bank experts, and citizens define their specific water problems. Overall, more than 60 prototype solutions were built in response to the 113 water sector challenges defined. Some
Private sector participation provides a promising solution to sustainable management and financing of water services, but we must bear in mind that a true PPP is all about the last P, partnership. At the Training Day preceding the PPP conference here in Dakar, Jane Jamieson said that PPP is not a date, it’s a marriage – you have to wake up next to it for the next 15-20 years (or 5 years or less for those management or lease/affermage contracts in countries such as Benin, Uganda, and Mozambique). So how do we make sure that it is indeed a true partnership?
Cooperation in International Waters in Africa (CIWA) was launched by the Africa Water Resources Management Unit of the World Bank.
The idea is for CIWA to support and assist riparian governments in Africa to work together to address and unlock the constraints on growth and development posed by international waters. The program is supported by various Development Partners, including the UK’s Department for International Development, Denmark and Norway.
