Editor's Note: 
The global water crisis is a crisis of too much, too polluted and too little. At the World Bank, our job is to find and implement solutions to tackle this crisis. In the “Water Solutions” blog series, you’ll read about World Bank-supported projects in different countries which demonstrated solutions to the world’s most pressing water issues, to fulfill our vision for a water-secure world.

Cities are growing at a staggering rate, changing our world beyond recognition. For the first time in history, over half the population -- 55 percent -- lives in urban areas.  By 2050, that number will rise to 68 percent.  This rapid urban growth has given rise to sprawling megacities, many of which are in Asia and Africa.

Perhaps no place epitomizes this trend better than Shanghai. In 1990, the city was still primarily an industrial hub with a population of 13 million. By 2016, the figure had ballooned to 24 million, making Shanghai one of the largest metropolitan areas in the world and the financial and economic hub of China. 

How to test water quality? Low-cost, low-tech options for microbial testing

Water quality is central to the challenge of ensuring safe water for all. Here we present the third entry in a three-part blog series on low-cost, low-tech water quality testing. In previous posts, we discussed options for measuring physical and chemical aspects of water quality. In this final post, we explore low-cost, low-tech options for microbial testing.

Money from waste? Revamp your view on sanitation

Daniel Ddiba's picture

As an undergraduate student in Kampala, my head was full of thoughts about how I was going to make a living after my studies. Back then Rich Dad Poor Dad was still a best-seller, and I thought to myself: I can become a billionaire if I sell a billion of something to a billion people. Needless to say, it would have to be something that anyone can afford, like toothpaste or chewing gum.
 
So, I wondered, what does every human need? It dawned on me: everyone needs water, food, and energy, every day. The next question was how I could make valuable goods from all the three as a civil engineer.

 

The shape of water for development

From July 9-18, more than 2,000 representatives from governments, businesses, civil society organizations and UN agencies gather for the High-level Political Forum on Sustainable Development. 


Water touches nearly every aspect of development. It flows through and connects the 17 Sustainable Development Goals (SDGs) by driving economic growth, supporting healthy ecosystems, cultivating food and energy production, and ensuring access to sanitation. We cannot achieve the SDGs without our collective action on water.

Avoiding pitfalls between policy and pipes

implementation via first-rate research
and analysis.

What motivates poor policy and investment decisions? Why do supposedly good policies not translate into practice? And how can we avoid perpetuating pitfalls between policy and pipes?
 

Our new paper ‘Aligning Institutions and Incentives for Sustainable Water Supply and Sanitation Services’, produced with the support of the Global Water Security and Sanitation Partnership (GWSP), examines precisely these issues. Through research, analysis, and case studies, the report posits that genuine, sustainable progress in water supply and sanitation service delivery is complex, iterative, and multi-faceted. Whether it’s expanding access, improving efficiency, or providing better services – all reforms require their own unique blend of policies, institutions and regulations and all take place in the context of their own unique enabling environment.

What does it take to achieve universal and equitable access to water and sanitation in Guatemala?

Water and sanitation data figures in Guatemala show a challenging reality. Nationally, 91 percent of the population has access to improved drinking water, an increase of 14 percent points since the establishment of the MDGs.
 
Despite the improvement in coverage in relative terms, in absolute terms there are still a significant number of Guatemalan households using water from precarious or unimproved sources such as unprotected wells, rivers, or lakes. In addition, water quality is a concern -- from the monitoring of 20% of the water systems in the country, 54% reported to be at high and imminent risk for human health.

Improved water is not enough

In Kinshasa, the capital and largest city of the Democratic Republic of the Congo (DRC), the vast majority of the population has access to “improved” water. This means sources such as piped networks, covered wells, boreholes, or protected springs, which are constructed to protect water from outside contamination, are widely available. Yet it is increasingly clear that “improved” water is not enough; when the 2017 DRC WASH Poverty Diagnostic tested water quality in over 1,600 households in Kinshasa, water samples from nearly 40% of improved sources were still contaminated with fecal E. Coli Bacteria at point of use.

Secrets to successful irrigation management from Central Asia

As delegates are gathering this week in Tajikistan for the High-Level International Conference on the International Decade for Action “Water for Sustainable Development,” 2018-2028, it is an opportune moment to share some lessons learned in improving gender inclusiveness in water management in Tajikistan.
 
Khatlon Region is one of the most populated areas of Tajikistan and located to the south of the conference venue in the nation’s capital of Dushanbe. About 60 percent of the region’s people are employed by the agricultural sector, which depends almost entirely on irrigation. However, growing numbers of rural women in Khatlon are being left behind to manage farms, while males migrate elsewhere in search of work. With little social and financial support, these women struggle to find productive roles in the irrigation management system that replaced the centralized Soviet model. Improving gender inclusiveness in irrigation management may improve the country’s food security, rural livelihood opportunities, and social stability.   

Can we regulate small and rural water supply and sanitation operators in Latin America?

Malva Baskovich's picture
The recent reforms in the water supply and sanitation (WSS) legal framework in Peru has given the National Superintendence of Water Supply and Sanitation Services of Peru (SUNASS) a new role in the regulation and supervision of service providers in small towns and rural communities, expanding its regulatory action beyond the urban area scope. Therefore, SUNASS needs to develop a regulatory framework and tools to effectively supervise around 28,000 small and rural operators, which provide service to 21% of the Peruvian population.
 
Delegates from SUNASS, with the support of the World Bank, visited different WSS sector entities in Colombia.


To achieve this goal, SUNASS, with the support of the World Bank, visited different WSS sector entities in Colombia which are responsible for the regulation, supervision and issuing policies regarding rural service provision. The objective of this South-South knowledge exchange was to gain valuable information from the Colombian counterparts about the challenges, lessons learned, and useful mechanisms for a successful reform process.
