More people today have access to a cell phone than to a clean toilet. At the current rate of progress the world will miss the global sanitation target for 2015 by over half a billion people. And while the drinking water global target was met last year, nearly a billion people still lack access to an improved drinking water source. Most of these statistics are well known by water and sanitation experts, and the wider development community. Perhaps, less known is the economic cost of the water and sanitation crisis.
The first Joint Sector Review and launch of the national Sector Investment Plan (SIP) for the Liberian water, sanitation and hygiene (WASH) sector will take place on February 5-7. With improved sector coordination and a new, systematic plan to achieve national objectives, Liberia is well-positioned to successfully tackle its WASH challenges – if sufficient funding is found.
Water supply and sanitation services are important for a whole host of reasons – time saving, dignity, convenience, economic growth, – including of course, public health. Yet it remains difficult to evaluate the extent to which those services actually do change health outcomes. Public health is affected by many variables, which interact in complex ways.
While on its path to becoming the largest city in the Americas, Sao Paulo used its natural capital - water - to generate electricity, fuel industry, and satiate its ever-growing population. Natural infrastructure was traded for the concrete form and the city’s great rivers paid a high price for industrialization.
The result? Tremendous growth (averaging 5% per annum) that stimulated rapid and unplanned migration to the city and environmental pollution. Urban sprawl generated little to no infrastructure for managing water, sanitation and wastewater, or solid waste. Clearing the land for houses caused erosion and compacted soils, and the resulting increase in runoff has made an already wet city even more prone to floods.
The city of Windhoek is probably best known for the fact that it is the world pioneer of drinking water reclamation from purified sewage effluent.
Windhoek lies in the heart of Namibia, the most arid Country in Sub Saharan Africa. All existing water resources are optimally utilized in a number of different ways. Integrated Urban Water Management (IUWM) lies at the heart of these approaches, both in using water that is fit for purpose and in diversifying water sources.

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.
