China’s experience in tackling water scarcity through sustainable agricultural water management

Sing Cho's picture

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.

Water scarcity is a pervasive problem across much of China. By the numbers, per capita water resources stand at only 2,100 cubic meters, which is one-fourth of the global average. Population growth, agricultural demands, and the adverse impacts of climate change further compound the challenge.
 
As China moves to secure water for all and provide a foundation for continued sustainable social, economic, and environmental development, there are many important lessons that have global relevance and application. 

Strengthening policy innovation for water use in agriculture

Lauren Nicole Core's picture

Experts from high-income countries and client countries came together last week during a joint World Bank-OECD workshop to discuss the shared goal of improving policy design and implementation for water use in agriculture. Although efficient use of water is becoming a central aim of agricultural practices, much work is yet to be done to meet steep water demands and curtail pollution from agricultural production.

An institutional view on Menstrual Hygiene Management

Christian Borja-Vega's picture
Recent research points out that adequate water, sanitation and hygiene (WASH) in schools improves school attendance, health and cognitive development of students, nurtures better WASH habits, while addressing gendered dimensions of exclusion. Despite this evidence, operationalizing and streamlining important Menstrual Hygiene Management (MHM) elements into interventions that upgrade overall school infrastructure is often challenging.

The problem is partially rooted in institutions, who having imperceptibly supplanted traditional & cultural rites of passage often fail to recognize the extent of the need for robust, wholistic and sustained alternatives. Girls experiencing menarche not only require WASH infrastructure, but meaning; they not only need materials, space and privacy to change and dispose of menstrual products, but an environment free from aspersions, taboo and social restriction.

A low-priced water reuse process that also delivers renewable energy in rural areas

What do Yucatan (Mexico), Michoacan (Mexico), Karur (India), and Jan Kempdorp (South Africa) have in common? These are all places with successful stories of implementing Anaerobic Digestion (AD) for wastewater treatment. But what is AD? What are the benefits?  

AD systems are installed for many different purposes, such as a waste treatment step, a means to reduce odours, a source of additional revenues, or a way to improve public image. The AD treats water and waste, reducing adverse environmental impacts. Through AD, two main by-products can be obtained: biogas—that can be used as a fuel, and sludge—that can be used as a soil amender for improve crops. These AD “by-products” are important in the context of mitigating the impacts of climate change, where environmental co-benefits come from efficient use of “by-products”. For instance, livestock enteric fermentation, livestock waste management, rice cultivation, and agricultural waste burning are all sources of methane emissions, representing between 7 and 10 percent of global methane emissions. AD not only treats water through an environmentally sustainable approach, but also contributes to produce high rates of methane for recovery and further utilization.

Becoming part of a mainstream movement – blended finance in water and sanitation

Ivaylo Kolev's picture
Persuasion does not always involve an epiphany. Often, attitudes are formed and opinions are shaped by the steady accumulation of evidence and examples. And so, it has been for me when it comes to blended finance.
 
While anecdotes of transformation may be catchier, the gradual absorption of the work of experts and practitioners is frequently how one’s thinking evolves. I left the recent 2018 Global Water Summit not feeling transformed or possessed by the idea that blended finance is THE solution for bridging the humongous financial gap required to meet SDG6, but more convinced than ever it has a key role to play. I was also positively surprised that this financial solution is no longer an exotic stranger to our sector and that a significant number of water supply and sanitation (WSS) practitioners are implementing blended finance schemes.

Blended Finance: a key to achieve universal access to water supply and sanitation by 2030

What does it take to finance sustainable water supply and sanitation? The World Bank Group takes this question very seriously indeed. That’s why during the recent Global Water Summit, the World Bank Group partnered with the organizer, Global Water Intelligence, to present the key concepts of Blended Finance to participants from all over the world.
 
But what is blended finance and why is the World Bank talking about it?

Thirsty Energy: A five-year journey to address water-energy nexus challenges

About 5 years ago we embarked on a global initiative titled “Thirsty Energy” to respond to water-energy nexus challenges around the world. The initiative, a joint effort of the Water and the Energy Global Practices at the World Bank, has finally come to an end. We wanted to reflect on the lessons learnt along the way, as our team has developed a fantastic set of material and methodologies to move the needle forward on this issue. We hope that the global community takes advantage of this to ignite change.

Connecting with the people beyond the computers: my experience in flood risk management in Buenos Aires

After spending several years in front of a computer every day, I began to feel removed from those people who were the real reason for my work, which aims to build a safer, healthier and more prosperous environment. But when people I knew were directly affected by the issues I was working on, my work took on more meaning and urgency.

The 8th World Water Forum was held in Brazil a few days ago. What's ironic is that the more than nine thousand of us attending this Forum were discussing water-related issues in a city of three million grappling with a severe water shortage. After checking in at my hotel, the first thing I found in my room was a notice from the Government informing guests of this crisis and recommending ways to reduce water use. We recently learned of the predicament in Cape Town, South Africa, which was on the verge of running out of this essential liquid—a plight facing many cities around the world.
