Amid pomp, traditional dance and splendor, in rural Chisamba, central Province, the President of Zambia, Edgar Chagwa Lungu, cut an elaborate ribbon donned in Zambian colors of red, black, green and orange to lay a foundation stone to mark the construction of the Mwomboshi Dam. The dam construction is funded by the World Bank under the Irrigation Development and Support Project (ISDP) with the amount of $37 million. Not only did I attend this significant ground-breaking ceremony as a representative of the World Bank Group (WBG), but I also took the opportunity to say a Bemba agriculture idiom I have been taught by my colleagues at the office.

New tactics to nudge habit change for open defecation behavior

Jacqueline Devine's picture
Open defecation remains a critical global health challenge, affecting almost 1 billion people around the world and contributing significantly to the estimated 842,000 people who die each year because of poor sanitation, hygiene practices, and unsafe water supplies [1].
 
Most behavior change approaches and frameworks for addressing open defecation have focused on relatively conscious, “reflective”  drivers of behavior, including people’s emotions (such as pride or shame), rational knowledge (e.g., of germ theory), social norms, and explicit action plans (such as commitments to change). Using the framework popularized by renowned social psychologist Daniel Kahneman [2].<, these factors can be described as “System 2” drivers of behavior i.e., relatively conscious and motivational factors. It is now well established, however, that human behavior can also be heavily influenced by “System 1” drivers i.e., relatively automatic, cue-driven factors [3].

Using green infrastructure to control urban floods: a win-win for cities

We have all come across people whose homes have beautiful and always blooming plants and flowers – people with a so-called “green thumb”.

But did you know that cities too can have a “green thumb”? Singapore is certainly one of those cities. 

Also known as the "garden city”, Singapore is set to become a "city in a garden”. The abundance of greenery is a striking feature, with parks, green roofs, street side plants, and trees on every corner.

But greenery is not there just to please the eye and create livable public areas — it also helps mitigate the risk of flooding.


Singapore, like many other densely-populated cities, is at risk of flooding. One way to tackle this is by greening public spaces and encouraging private development to follow the principles of the government’s flagship “ABC” program, which looks to make water “Active, Beautiful and Clean”. Carefully planned and implemented, investments in so-called “green infrastructure” are paying off: they make the city more resilient and more sustainable in the long-term, and also create more spaces for people to meet and interact.

Although Singapore’s dedication to greening public spaces is remarkable, it is not the only city that is getting its hands “dirty” to promote natural ecosystems. The Netherlands has been promoting green approaches in urban planning for many years now, with the innovative redesign of sewer systems, or the creation of multi-functional “water squares” which can hold storm water when rain is heavy while otherwise serving as a social space.

New approaches in water resource economics

Susanne M. Scheierling's picture
In many parts of the world, changing demand and supply patterns are contributing to an increasing physical scarcity and competition for water resources. Historically, new demands have been met by developing additional supplies—with the incremental cost of water remaining relatively constant over time due to the ready availability of water development project sites to meet growing demands. As the water economy moves from an expansionary to a mature phase, incremental costs are sharply rising, and interdependencies among users and uses are greatly increasing. With this move, the issues to be addressed by water economists tend to become more pressing, broader and more complex. While in the expansionary phase structural or engineering approaches to water management tend to be the main focus, in a maturing water economy nonstructural or institutional options for solving water problems receive increasing attention. In particular, resource allocation and valuation issues move to the forefront of economic inquiry.

Solar Irrigation Pumps: A New Way of Agriculture in Bangladesh

On a recent field trip to northern Bangladesh, the smiles of Habibur, a young man working in a rice field under the scotching sun caught my attention. Habibur, 28, looked content amidst the wide green vista of fields.  
I learned that his life had not been easy. His father died when Habibur was around four years old, and the family had no land. His young widowed mother started working as a day laborer to raise her only child. Habibur began working too in his mid-teens. Mother and son struggled, but they managed to save some money.  They first bought a cow, and later Habibur leased land for rice cultivation. This is a common practice in rural Bangladesh, where the yield is divided between the farmer and the owner of the land.

What Vietnam can learn from Singapore about flood risk management

As Vietnamese, we look very fondly to Singapore as a model for development in the region, especially fostered by a close relationship between Vietnamese leaders and the former Minister Mentor Lee Kuan Yew—Singapore's founder and mastermind behind all its modern-day achievements. Singapore represents modernity and civilization, notably with limited natural resources. The city-state has proved an applicable model of development for cities in Vietnam to achieve not only competitiveness but also sustainability and inclusiveness.
 
I just returned to Vietnam after attending the World Bank’s first-ever Urban Week in Singapore, a series of events that brought together city leaders from across Asia and beyond to explore innovative approaches to urban planning and management.
 
A topic that cut across all these areas is flood risk management, which was featured extensively during the launch event of the Global Platform for Sustainable Cities. I had the opportunity to learn more about the role of green mitigation infrastructure in integrated urban flood risk management, with lessons from Japan, Korea, Sri Lanka, Senegal, and the Netherlands. In these countries, green structures such as retarding basins, permeable pavement, and rainwater storage or infiltration trench have complemented conventional structural measures to reduce flood risk in a cost-effective manner.

Singapore: the beautiful city state, famed for its lush gardens, splendid food, culturally diverse communities, and the cocktail Singapore Sling. I was there last week for the World Bank’s 2016 Urban Week. The event brought together leading city officials from all over the world and staff from international organizations. It was an excellent exchange on how to tackle urban planning in a sustainable and integrated way. One lesson that emerged from the gathering is that cities that are resilient to natural disasters are also more economically competitive. Singapore is itself a prime example of a city that has understood the importance of connecting disaster risk management, urban planning, and quality living.

Yemen: so critically short of water in war that children are dying fetching it

Before the ongoing war, Yemen was already among those countries facing the most serious water shortages: experts warned that its groundwater would be depleted by 2017. The war has greatly exacerbated the situation as, along with instability, the absence of government, and spread of armed conflicts, the arbitrary pumping of groundwater has increased while government utilities like water supplies have collapsed.

World Water Day: Transforming lives through better water and jobs

Water covers 70% of Earth’s surface, but if you live in Sana’a, Sao Paolo, California, or the many other areas where drought or chronic water scarcity has affected daily life, you know that abundance can be relative.

This image from the US Geological Survey shows that only a tiny fraction of Earth’s water is the accessible freshwater we need to live, grow food, sustain the environment, and power our cities and jobs.

Growing cities and populations and a changing climate are placing unprecedented pressures on water. According to the World Economic Forum, water crises are among the top risks to global economic growth. For at least 650 million people, even the water they are able to find is unsafe.

But this also offers an opportunity to provide safer water and better manage our water resources for a more resilient future.

This year, #worldwaterday focuses on the connection between water and jobs, and these connections primarily fall under two categories: productivity and sustainability.
