Cities over the past century have become the driving force of the global economy. Accounting for over half the world’s population and generating around 80% of global GDP, cities provide numerous opportunities for development and growth. Cities however bring about risks and challenges to people and the environment. By 2050, demand for water is projected to increase by 55% mainly due to increased demand from urban populations. At the same time
Ending poverty is within our reach. The percentage of people living in extreme poverty has more than halved since 1990, thanks to the sustained efforts of countless individuals, organizations and nations.
Amina and her family had recently moved to their new house on the outskirts of Dakar, Senegal. It was built by the government to relocate families from low-lying and flood-prone neighborhoods in the city. The house was small for her extended family of ten, but it was water that she worried about. I was puzzled. Usually people complain that water connection costs are too high, but she received that connection for free—the meter and tap were right there in her front yard.
Why did she worry?
Niger is one of the world’s poorest countries (44.5% of poverty incidence in 2014). The country faces a number of challenges in meeting the national (PROSEHA, the National Program for sustainable development) and global targets to increase access to sanitation and potable water, particularly in rural areas where the access to water is 44.2% and 7% for sanitation (2015 Ministry of Water and Sanitation data).
Overcoming these challenges while satisfying increasing demands for better or expanded service, the government began investigating options that bring in the know-how of the private sector. This has led to a growing domestic private sector provision of services in Niger.

with an economic value of over US$3 billion per year.
A World Bank study puts , half of which occurs in developing countries. Water utilities suffer from the huge financial costs of treating and pumping water only to see it leak back into the ground, and the lost revenues from water that could have otherwise been sold. If the water losses in developing countries could be halved, the saved water would be enough to supply around 90 million people.
We refer to it as non-revenue water (NRW), or water that is pumped and then lost or unaccounted for.
The need to manage NRW better and protect precious water resources has become increasingly important. , enhance financial performance, make cities more attractive, increase climate resilience and reduce energy consumption.
Sustainable Development Goal (SDG) 6 targets “universal and equitable access to safe and affordable drinking water for all”. However,
However, some cities stand out as exceptions. to almost all of their inhabitants? A study I led recently, Providing Water to Poor People in African Cities Effectively: Lessons from Utility Reforms, analyzed how the water utilities in Kampala, Nyeri, Dakar, Ouagadougou and Durban achieved stand-out performance, and how this made a difference for the poor people in these cities.
For every person in Iceland, there are over 200 olympic swimming pools worth of renewable freshwater. However, nearly 1.6 billion people live in countries where water is scarce – a figure that may double in the coming two decades. Annual renewable freshwater levels in Central Asia are expected to diminish to 1,700 m per person - less than one pool's worth by 2030. The theme of this year's World Water Week is "Water for Sustainable Growth". Read more.
With the adoption of the Sustainable Development Goals on water and sanitation (SDG 6), countries of the world committed themselves to change this situation by achieving universal access to safe water and sanitation while addressing issues of water quality and scarcity to balance the needs of households, agriculture, industry, energy, and the environment over the next 15 years.
Recent estimates by the World Bank’s Water and Sanitation Program (WSP) indicate that the present value of the additional investment in the water and sanitation sector alone needed through 2030 will exceed US$1.7 trillion. Existing funding falls far short of this amount; .
At present, most water sector actors in developing countries rely on government lending and concessional financing from national, bilateral or multilateral development banks (MDBs) to mobilize financing for capital investment. These financial sources alone will not be sufficient to finance investments on the scale that is called for by the SDGs. It is therefore essential to mobilize up-front financing from commercial sources as well.
National governments and donors must use their funds in a catalytic manner, as part of broader financing strategies that mobilize funding from sector efficiency gains, tariffs, domestic taxes, and transfers to crowd in domestic commercial finance. If they are able to do so, countries will be much more likely to access the resources they need to improve and expand the infrastructure needed to deliver and sustain universal coverage of water and sanitation services and achieve SDG 6.

Two years ago, during the 2014 SIWI World Water Week, key international experts discussed the need for a paradigm shift in water consumption: the move from a linear to a circular economy—an economy that is restorative and regenerative by design, and which aims to keep products, components and materials at their highest utility and value at all times.
With global demand for water predicted to exceed viable resources by 40 percent in 2030,and adopt new approaches that allow for this vital resource to be reused as much as possible, and achieve efficient standards for water management.
These previous SIWI World Water Week discussions allowed raising awareness about the adoption of a circular economy as a viable sustainable development strategy; its particular relevance to the water sector, in view of the fundamental and cross-cutting role it has across all sectors; and the combination of regulations and incentives, and strong multi-stakeholder approach, required to allow the market to transform.—moving away from traditional linear water consumption patterns of “take-make-dispose” and heading towards a circular economy approach where wastewater is no longer seen as waste or an environmental hazard, but rather as a valuable resource that contributes to overcome water stress and imbalances between supply and demand —is particularly relevant to the Latin American region, and the 2016 SIWI World Water Week event of this year will take this conversation forward.
